INTRODUCTION
Paul Henri Thiery, Baron d'Holbach (1723-1789), was the center of the radical wing of the philosophes. He was friend, host, and patron to a wide circle that included Diderot, D'Alembert, Helvetius, and Hume. Holbach wrote, translated, edited, and issued a stream of books and pamphlets, often under other names, that has made him the despair of bibliographers but has connected his name, by innuendo, gossip, and association, with most of what was written in defense of atheistic materialism in late eighteenth-century France.
Holbach is best known for The System of Nature (1770) and deservedly, since it is a clear and reasonably systematic exposition of his main ideas. His initial position determines all the rest of his argument. "There is not, there can be nothing out of that Nature which includes all beings." Conceiving of nature as strictly limited to matter and motion, both of which have always existed, he flatly denies that there is any such thing as spirit or a supernatural. Mythology began, Holbach claims, when men were still in a state of nature and at the point when wise, strong, and for the most part benign men were arising as leaders and lawgivers. These leaders "formed discourses by which they spoke to the imaginations of their willing auditors," using the medium of poetry, because it "seem{ed} best adapted to strike the mind." Through poetry, then, and by means of "its images, its fictions, its numbers, its rhyme, its harmony... the entire of nature, as well as all its parts, was personified, by its beautiful allegories." Thus mythology is given an essentially political origin. These early poets are literally legislators of mankind. "The first institutors of nations, and their immediate successors in authority, only spoke to the people by fables, allegories, enigmas, of which they reserved to themselves the right of giving an explanation." Holbach is rather condescending about the process, but since mythology is a representation of nature itself, he is far more tolerant of mythology than he is of the next step. "Natural philosophers and poets were transformed by leisure into metaphysicians and theologians," and at this point a fatal error was introduced: the theologians made a distinction between the power of nature and nature itself, separated the two, made the power of nature prior to nature, and called it God. Thus man was left with an abstract and chimerical being on one side and a despoiled inert nature, destitute of power, on the other. In Holbach's critique the point at which theology split off from mythology marks the moment of nature's alienation from itself and paves the way for man's alienation from nature.
Holbach is thus significant for Romantic interest in myth in two ways. First, he provides a clear statement of what can be loosely called the antimythic position, that rationalist condescension and derogation of all myth and all religion that was never far from the surface during the Romantic era. Holbach was and is a reminder that the Romantic affirmation of myth was never easy, uncritical, or unopposed. Any new endorsement of myth had to be made in the teeth of Holbach and the other skeptics. The very vigor of the Holbachian critique of myth impelled the Romantics to think more deeply and defend more carefully any new claim for myth. Secondly, although Holbach's argument generally drove against myth and religion both, he did make an important, indeed a saving distinction between mythology and theology. Mythology is the more or less harmless personification of the power in and of nature; theology concerns itself with what for Holbach was the nonexistent power beyond or behind nature. By exploiting this distinction it would become possible for a Shelley, for example, to take a strong antitheological—even an anti-Christian—position without having to abandon myth.
Holbach was one of William Godwin's major sources for his ideas about political justice, and Shelley, who discussed Holbach with Godwin, quotes extensively from The System of Nature in Queen Mab. Furthermore, Volney's Ruins, another important book for Shelley, is directly descended from The System of Nature. On the other side, Holbach was a standing challenge to such writers as Coleridge and Goethe and was reprinted and retranslated extensively in America, where his work was well known to the rationalist circle around Jefferson and Barlow.
Issued in 1770 as though by Jean Baptiste de Mirabaud (a former perpetual secretary to the Académie française who had died ten years before), La Système de la nature was translated and reprinted frequently. The Samuel Wilkinson translation we have chosen to reprint was the most often reprinted or pirated version in English. A useful starting point for Holbach's work is Jerome Vercruysse, Bibliographie descriptive des écrits du baron d'Holbach (Paris, 1971). The difficult subject of the essentially clandestine evolution of biblical criticism as an anti-Christian and antimyth critique in the early part of the eighteenth century, before the well-documented era of the biblical critic Eichhorn in Germany, is illuminated in Ira Wade, The Clandestine Organization and Diffusion of Philosophic Ideas in France from 1700-1750 (Princeton Univ. Press, 1938).

PREFACE
The source of man's unhappiness is his ignorance of Nature. The pertinacity with which he clings to blind opinions imbibed in his infancy, which interweave themselves with his existence, the consequent prejudice that warps his mind, that prevents its expansion, that renders him the slave of fiction, appears to doom him to continual error. He resembles a child destitute of experience, full of ideal notions: a dangerous leaven mixes itself with all his knowledge: it is of necessity obscure, it is vacillating and false:—He takes the tone of his ideas on the authority of others, who are themselves in error, or else have an interest in deceiving him. To remove this Cimmerian darkness, these barriers to the improvement of his condition; to disentangle him from the clouds of error that envelope him; to guide him out of this Cretan labyrinth, requires the clue of Ariadne, with all the love she could bestow on Theseus. It exacts more than common exertion; it needs a most determined, a most undaunted courage—it is never effected but by a persevering resolution to act, to think for himself; to examine with rigour and impartiality the opinions he has adopted. He will find that the most noxious weeds have sprung up beside beautiful flowers; entwined themselves around their stems, overshadowed them with an exuberance of foliage, choaked the ground, enfeebled their growth, diminished their petals; dimmed the brilliancy of their colours; that deceived by their apparent freshness of their verdure, by the rapidity of their exfoliation, he has given them cultivation, watered them, nurtured them, when he ought to have plucked out their very roots.
Man seeks to range out of his sphere: notwithstanding the reiterated checks his ambitious folly experiences, he still attempts the impossible; strives to carry his researches beyond the visible world; and hunts out misery in imaginary regions. He would be a metaphysician before he has become a practical philosopher. He quits the contemplation of realities to meditate on chimeras. He neglects experience to feed on conjecture, to indulge in hypothesis. He dares not cultivate his reason, because from his earliest days he has been taught to consider it criminal. He pretends to know his date in the indistinct abodes of another life, before he has considered of the means by which he is to render himself happy in the world he inhabits: in short, man disdains the study of Nature, except it be partially: he pursues phantoms that resemble an ignis-fatuus, which at once dazzle, bewilders, and affright: like the benighted traveller led astray by these deceptive exhalations of a swampy soil, he frequently quits the plain, the simple road of truth, by pursuing of which, he can alone ever reasonably hope to reach the goal of happiness.
The most important of our duties, then, is to seek means by which we may destroy delusions that can never do more than mislead us. The remedies for these evils must be sought for in Nature herself; it is only in the abundance of her resources, that we can rationally expect to find antidotes to the mischiefs brought upon us by an ill directed, by an overpowering enthusiasm. It is time these remedies were sought; it is time to look the evil boldly in the face, to examine its foundations, to scrutinize its superstructure: reason, with its faithful guide experience, must attack in their entrenchments those prejudices, to which the human race has but too long been the victim. For this purpose reason must be restored to its proper rank,—it must be rescued from the evil company with which it is associated. It has been too long degraded—too long neglected—cowardice has rendered it subservient to delirium, the slave to falsehood. It must no longer be held down by the massive claims of ignorant prejudice.
Truth is invariable—it is requisite to man—it can never harm him—his very necessities, sooner or later, make him sensible of this; oblige him to acknowledge it. Let us then discover it to mortals—let us exhibit its charms—let us shed it effulgence over the darkened road; it is the only mode by which man can become disgusted with that disgraceful superstition which leads him into error, and which but too often usurps his homage by treacherously covering itself with the mask of truth—its lustre can wound none but those enemies to the human race whose power is bottomed solely on the ignorance, on the darkness in which they have in almost every claimed contrived to involve the mind of man.
Truth speaks not to those perverse beings:—her voice can only be heard by generous souls accustomed to reflection, whose sensibilities make them lament the numberless calamities showered on the earth by political and religious tyranny—whose enlightened minds contemplate with horror the immensity, the ponderosity of that series of misfortunes which error has in all ages overwhelmed mankind.
To error must be attributed those insupportable chains which tyrants, which priests have forged for most nations. To error must be equally attributed that abject slavery into which the people of almost every country have fallen. Nature designed they should pursue their happiness by the most perfect freedom.—To error must be attributed those religious terrors which, in almost every climate, have either petrified man with fear, or caused him to destroy himself for coarse or fanciful beings. To error must be attributed those inveterate hatreds, those barbarous persecutions, those numerous massacres, those dreadful tragedies, of which, under pretext of serving the interests of heaven, the earth has been but too frequently made the theatre. It is error consecrated by religious enthusiasm, which produces that ignorance, that uncertainty in which man ever finds himself with regard to his most evident duties, his clearest rights, the most demonstrable truths. In short, man is almost everywhere a poor degraded captive, devoid of greatness of soul, of reason, or of virtue, whom his inhuman gaolers have never permitted to see the light of day.
Let us then endeavour to disperse those clouds of ignorance, those mists of darkness, which impede man on his journey, which obscure his progress, which prevent his marching through life with a firm, with a steady grip. Let us try to inspire him with courage—with respect for his reason—with an inextinguishable love for truth—with a remembrance of Gallileo—to the end that he may learn to know himself—to know his legitimate rights—that he may learn to consult his experience, and no longer be the dupe of an imagination led astray by authority—that he may renounce the prejudices of his childhood—that he may learn to found his morals on his nature, on his wants, on the real advantage of society—that he may dare to love himself—that he may learn to pursue his true happiness by promoting that of others—in short, that he may no longer occupy himself with reveries either useless or dangerous—that he may become a virtuous, a rational being, in which case he cannot fail to become happy.
If he must have his chimeras, let him at least learn to permit others to form theirs after their own fashion; since nothing can be more immaterial than the manner of men's thinking on subjects not accessible to reason, provided those thoughts be not suffered to embody themselves into actions injurious to others: above all, let him be fully persuaded that it is of the utmost importance to the inhabitants of this world to be JUST, KIND, and PEACEABLE.
Far from injuring the cause of virtue, an impartial examination of the principles of this work will shew that its object is to restore truth to its proper temple, to build up an altar whose foundations shall be consolidated by morality, reason, and justice: from this sacred pane, virtue guarded by truth, clothed with experience, shall shed forth her radiance on delighted mortals; whose homage flowing consecutively shall open to the world a new aera, by rendering general the belief that happiness, the true end of man's existence, can never be attained but BY PROMOTING THAT OF HIS FELLOW CREATURE.
In short, man should learn to know, that happiness is simply an emanative quality formed by reflection; that each individual ought to be the sun of his own system, continually shedding around him his genial rays; that these, re-acting, will keep his own existence constantly supplied with the requisite heat to enable him to put forth kindly fruit.

LAWS OF NATURE—OF MAN—THE FACULTIES OF THE SOUL—DOCTRINE OF IMMORTALITY—ON HAPPINESS.
CHAP. I.
Nature and her Laws.
Man has always deceived himself when he abandoned experience to follow imaginary systems.—He is the work of nature.—He exists in Nature.—He is submitted to the laws of Nature.—He cannot deliver himself from them:—cannot step beyond them even in thought. It is in vain his mind would spring forward beyond the visible world: direful and imperious necessity ever compels his return—being formed by Nature, he is circumscribed by her laws; there exists nothing beyond the great whole of which he forms a part, of which he experiences the influence. The beings his fancy pictures as above nature, or distinguished from her, are always chimeras formed after that which he has already seen, but of which it is utterly impossible he should ever form any finished idea, either as to the place they occupy, or their manner of acting—for him there is not, there can be nothing out of that Nature which includes all beings.
Therefore, instead of seeking out of the world he inhabits for beings who can procure him a happiness denied to him by Nature, let him study this Nature, learn her laws, contemplate her energies, observe the immutable rules by which she acts.—Let him apply these discoveries to his own felicity, and submit in silence to her precepts, which nothing can alter.—Let him cheerfully consent to be ignorant of causes hid from him under the most impenetrable veil.—Let him yield to the decrees of a universal power, which can never be brought within his comprehension, nor ever emancipate him from those laws imposed on him by his essence.
The distinction which has been so often made between the physical and the moral being, is evidently an abuse of terms. Man is a being purely physical: the moral man is nothing more than this physical being considered under a certain point of view; that is to say, with relation to some of his modes of action, arising out of his individual organization. But is not this organization itself the work of Nature? The motion or impulse to action, of which he is susceptible, is that not physical? His visible actions, as well as the invisible motion interiorly excited by his will or his thoughts, are equally the natural effects, the necessary consequences, of his peculiar construction, and the impulse he receives from those beings by whom he is always surrounded. All that the human mind has successively invented, with a view to change or perfect his being, to render himself happy, was never more than the necessary consequence of man's peculiar essence, and that of the beings who act upon him. The object of all his institutions, all his reflections, all his knowledge, is only to procure that happiness toward which he is continually impelled by the peculiarity of his nature. All that he does, all that he thinks, all that he is, all that he will be, is nothing more than what Universal Nature has made him. His ideas, his actions, his will, are the necessary effects of those properties infused into him by Nature, and of those circumstances in which she has placed him. In short, art is nothing but Nature acting with the tools she has furnished.
Nature sends man naked and destitute into this world which is to be his abode: he quickly learns to cover his nakedness—to shelter himself from the inclemencies of the weather, first with artlessly constructed huts, and the skins of the beasts of the forest; by degrees he mends their appearance, renders them more convenient: he establishes manufactories to supply his immediate wants; he digs clay, gold, and other fossils from the bowels of the earth; converts them into bricks for his house, into vessels for his use, gradually improves their shape, and augments their beauty. To a being exalted above our terrestrial globe, man would not appear less subjected to the laws of Nature when naked in the forest painfully seeking his sustenance, than when living in civilized society surrounded with ease, or enriched with greater experience, plunged in luxury, where he every day invents a thousand new wants and discovers a thousand new modes of supplying them. All the steps taken by man to regulate his existence, ought only to be considered as a long succession of causes and effects, which are nothing more than the development of the first impulse given him by nature.
The same animal, by virtue of his organization, passes successively from the most simple to the most complicated wants; it is nevertheless the consequence of his nature. The butterfly whose beauty we admire, whose colours are so rich, whose appearance is so brilliant, commences as an inanimate unattractive egg; from this, heat produces a worm, this becomes a chrysalis, then changes into that beautiful insect adorned with the most vivid tints: arrived at this stage he reproduces, he generates; at last despoiled of his ornaments, he is obliged to disappear, having fulfilled the task imposed on him by Nature, having performed the circle of transformation marked out for beings of his order.
The same course, the same change takes place in the vegetable world. It is by a series of combinations originally interwoven with the energies of the aloe, that this plant is insensibly regulated, gradually expanded, and at the end of a number of years produces those flowers which announce its dissolution.
It is equally so with man, who in all his motion, all the changes he undergoes, never acts but according to the laws peculiar to his organization, and to the matter of which he is composed.
The physical man, is he who acts by the causes our faculties make us understand.
The moral man, is he who acts by physical causes, with which our prejudices preclude us from becoming perfectly acquainted.
The wild man is a child destitute of experience, incapable of proceeding in his happiness, because he has not learnt how to oppose resistance to the impulses he receives from those beings by whom he is surrounded.
The civilized man, is he whom experience and sociality have enabled to draw from nature the means of his own happiness, because he has learned to oppose resistance to those impulses he receives from exterior beings, when experience has taught him they would be destructive to his welfare.
The enlightened man is man in his maturity, in his perfection; who is capable of advancing his own felicity, because he has learned to examine, to think for himself, and not to take that for truth upon the authority of others, which experience has taught him a critical disquisition will frequently prove erroneous.
The happy man is he who knows how to enjoy the benefits bestowed upon him by nature: in other words, he who thinks for himself; who is thankful for the good he possesses; who does not envy the welfare of others, nor sigh after imaginary benefits always beyond his grasp.
The unhappy man is he who is incapacitated to enjoy the benefits of nature; that is, he who suffers others to think for him; who neglects the absolute good he possesses, in a fruitless search after ideal benefits; who vainly sighs after that which ever eludes his pursuit.
It necessarily results, that man in his enquiry ought always to contemplate experience, and natural philosophy: These are what he should consult in his religion,—in his morals,—in his legislation,—in his political government,—in the arts,—in the sciences,—in his pleasures,—above all, in his misfortunes. Experience teaches that Nature acts by simple, regular, and invariable laws. It is by his senses, man is bound to this universal Nature; it is by his perception he must penetrate her secrets; it is from his senses he must draw experience of her laws. Therefore, whenever he neglects to acquire experience or quits its path, he stumbles into an abyss; his imagination leads him astray.
All the errors of man are physical: he never deceives himself but when he neglects to return back to nature, to consult her laws, to call practical knowledge to his aid. It is for want of practical knowledge he forms such imperfect ideas of matter, of its properties, of its combinations, of its power, of its mode of action, and of the energies which spring from its essence. Wanting this experience, the whole universe, to him, is but one vast scene of error. The most ordinary results appear to him the most astonishing phenomena; he wonders at every thing, understands nothing, and yields the guidance of his actions to those interested in betraying his interests. He is ignorant of Nature, and he has mistaken her laws; he has not contemplated the necessary routine which she has marked out for every thing she holds. Mistaken the laws of Nature, did I say? He has mistaken himself: the consequence is, that all his systems, all his conjectures, all his reasonings, from which he has banished experience, are nothing more than a tissue of errors, a long chain of inconsistencies.
Error is always prejudicial to man: it is by deceiving himself, the human race is plunged into misery. He neglected Nature; he did not comprehend her laws; he formed gods of the most preposterous and ridiculous kinds: these became the sole objects of his hope, and the creatures of his fear: he was unhappy, he trembled under these visionary deities; under the supposed influence of visionary beings created by himself; under the terror inspired by blocks of stone; by logs of wood; by flying fish; or the frowns of men, mortal as himself, whom his disturbed fancy had elevated above that Nature of which alone he is capable of forming any idea. His very posterity laughs at his folly, because experience has convinced them of the absurdity of his groundless fears—of his misplaced worship. Thus has passed away the ancient mythology, with all the trifling and nonsensical attributes attached to it by ignorance.
Not understanding that Nature, equal in her distributions, entirely destitute of malice, follows only necessary and immutable laws, when she either produces beings or destroys them, when she causes those to suffer, whose construction creates sensibility; when she scatters among them good and evil; when she subjects them to incessant change—he did not perceive it was in the breast of Nature herself, that it was in her exuberance he ought to seek to satisfy his deficiencies; for remedies against his pains; for the means of rendering himself happy: he expected to derive these benefits from fantastic beings, whom he supposed to be above Nature; whom he mistakingly imagined to be the authors of his pleasures, and the cause of his misfortunes. From hence it appears that to his ignorance of Nature, man owes the creation of those illusive powers; under which he has so long trembled with fear; that superstitious worship, which has been the source of all his misery, and the evils entailed upon posterity.
For want of clearly comprehending his own peculiar nature, his proper course, his wants, and his rights, man has fallen in society, from FREEDOM into SLAVERY. He had forgotten the purpose of his existence, or else he believed himself obliged to suppress the natural desires of his heart, to sacrifice his welfare to the caprice of chiefs, either elected by himself, or submitted to without examination. He was ignorant of the true policy of association—of the object of government; he disdained to listen to the voice of Nature, which loudly proclaimed the price of all submission to be protection and happiness: the end of all government is the benefit of the governed, not the exclusive advantage of the governors. He gave himself up without enquiry to men like himself, whom his prejudices induced him to contemplate as beings of a superior order, as Gods upon earth, they profited by his ignorance, took advantage of his prejudices, corrupted him, rendered him vicious, enslaved him, and made him miserable. Thus man, intended by Nature for the full enjoyment of liberty, to patiently search out her laws, to investigate her secrets, to cling to his experience; has, from a neglect of her salutary admonitions, from an inexcusable ignorance of his own peculiar essence, fallen into servility: has been wickedly governed.
Having mistaken himself, he has remained ignorant of the indispensable affinity that subsists between him, and the beings of his own species: having mistaken his duty to himself, it consequently follows, he has mistaken his duty to others. He made a calculation in error of what his happiness required; he did not perceive, what he owed to himself, the excesses he ought to avoid, the desires he ought to resist, the impulses he ought to follow, in order to consolidate his felicity, to promote his comfort, and to further his advantage. In short, he was ignorant of his true interests; hence his irregularities, his excesses, his shameful extravagance, with that long train of vices, to which he has abandoned himself, at the expense of his preservation, at the hazard of his permanent prosperity.
It is, therefore, ignorance of himself that has hindered man from enlightening his morals. The corrupt authorities to which he had submitted, felt an interest in obstructing the practice of his duties, even when he knew them. Time, with the influence of ignorance, aided by his corruption, gave them a strength not to be resisted by his enfeebled voice. His duties continued unperformed, and he fell into contempt both with himself and with others.
The ignorance of Man has endured so long, he has taken such slow, such irresolute steps to ameliorate his condition, only because he has neglected to study Nature, to scrutinize her laws, to search out her expedients, to discover her properties, that his sluggishness finds its account, in permitting himself to be guided by example, rather than to follow experience, which demands activity; to be led by routine, rather than by his reason, which enjoins reflection; to take that for truth upon the authority of others, which would require a diligent and patient investigation. From hence may be traced the hatred man betrays for every thing that deviates from those rules to which he has been accustomed; hence his stupid, his scrupulous respect for antiquity, for the most silly, the most absurd and ridiculous institutions of his fathers: hence those fears that seize him, when the most beneficial changes are proposed to him, or the most likely attempts are made to better his condition. He dreads to examine, because he has been taught to hold it irreverent of something immediately connected with his welfare; his credulity suffers him to believe the interested advice, and spurns at those who wish to show him the danger of the road he is travelling.
This is the reason why nations linger on in the most shameful lethargy, suffering under abuses handed down from century to century, trembling at the very idea of that which alone can repair their calamities.
It is for want of energy, for want of consulting experience, that medicine, natural philosophy, agriculture, painting, in fact, all the useful sciences, have so long remained under the fetters of authority, have progressed so little: those who profess these sciences, prefer treading the beaten paths, however imperfect, rather than strike out new ones,—they prefer the phrensy of their imagination, their voluntary conjectures, to that laboured experience which alone can extract her secrets from Nature.
Man, in short, whether from sloth or from terror, having abnegated the evidence of his senses, has been guided in all his actions, in all his enterprizes, by imagination, by enthusiasm, by habit, by preconceived opinions, but above all, by the influence of authority, which knew well how to deceive him, to turn his ignorance to esteem, his sloth to advantage. Thus imaginary, unsubstantial systems, have supplied the place of experience—of mature reflection—of reason. Man, petrified with his fears, intoxicated with the marvellous, stupified with sloth, surrendered his experience: guided by his credulity, he was unable to fall back upon it; he became consequently inexperienced; from thence he gave birth to the most ridiculous opinions, or else adopted all those vague chimeras, all those idle notions offered to him by men whose interest it was to continue him in that lamentable state of ignorance.
Thus the human race has continued so long in a state of infancy, because man has been inattentive to Nature; has neglected her ways, because he has disdained experience—because he has thrown by his reason—because he has been enraptured with the marvellous and the supernatural,—because he has unnecessarily TREMBLED. These are the reasons there is so much trouble in conducting him from this state of childhood to that of manhood. He has had nothing but the most trifling hypotheses, of which he has never dared to examine either the principles or the proofs, because he has been accustomed to hold them sacred, to consider them as the most perfect truths, and which he is not permitted to doubt, even for an instant. His ignorance made him credulous; his curiosity made him swallow the wonderful: time confirmed him in his opinions, and he passed his conjectures from race to race for realities; a tyrannical power maintained him in his notions, because by those alone could society be enslaved. It was in vain that some faint glimmerings of Nature occasionally attempted the recall of his reason—that slight corruscations of experience sometimes threw his darkness into light, the interest of the few was founded on his enthusiasm; their pre-eminence depended on his love of the marvellous; their very existence rested on the firmness of his ignorance; they consequently suffered no opportunity to escape, of smothering even the transient flame of intelligence. The many were thus first deceived into credulity, then forced into submission. At length the whole science of man became a confused mass of darkness, falsehood, and contradictions, with here and there a feeble ray of truth, furnished by that Nature, of which he can never entirely divest himself; because, without his perception, his necessities are continually bringing him back to her resources.
Let us then, if possible, raise ourselves above these clouds of prepossession! Let us quit the heavy atmosphere in which we are enucleated; let us in a more unsullied medium—in a more elastic current, contemplate the opinions of men, and observe their various systems. Let us learn to distrust a disordered conception; let us take that faithful monitor, experience, for our guide; let us consult Nature, examine her laws, dive into her stores; let us draw from herself, our ideas of the beings she contains; let us recover our senses, which interested error has taught us to suspect; let us consult that reason, which, for the vilest purposes has been so infamously calumniated, so cruelly dishonoured; let us examine with attention the visible world; let us try, if it will not enable us to form a supportable judgment of the invisible territory of the intellectual world: perhaps it may be found there has been no sufficient reason for distinguishing them—that it is not without motives, well worthy our enquiry, that two empires have been separated, which are equally the inheritance of nature.
The universe, that vast assemblage of every thing that exists, presents only matter and motion: the whole offers to our contemplation, nothing but an immense, an uninterrupted succession of causes and effects; some of these causes are known to us, because they either strike immediately on our senses, or have been brought under their cognizance, by the examination of long experience; others are unknown to us, because they act upon us by effects, frequently very remote from their primary cause. An immense variety of matter, combined under an infinity of forms, incessantly communicates, unceasingly receives a diversity of impulses. The different qualities of this matter, its innumerable combinations, its various methods of action, which are the necessary consequence of these associations, constitute for man what he calls the ESSENCE of beings: it is from these varied essences that spring the orders, the classes, or the systems, which these beings respectively possess, of which the sum total makes up that which is known by the term nature.
Nature, therefore, in its most significant meaning, is the great whole that results from the collection of matter, under its various combinations, with that contrariety of motion, which the universe presents to our view. Nature, in a less extended sense, or considered in each individual, is the whole that results from its essence; that is to say, the peculiar qualities, the combination, the impulse, and the various modes of action, by which it is discriminated from other beings. It is thus that MAN is, as a whole, or in his nature, the result of a certain combination of matter, endowed with peculiar properties, competent to give, capable of receiving, certain impulses, the arrangement of which is called organization; of which the essence is, to feel, to think, to act, to move, after a manner distinguished from other beings, with which he can be compared. Man, therefore, ranks in an order, in a system, in a class by himself, which differs from that of other animals, in whom we do not perceive those properties of which he is possessed. The different systems of beings, or if they will, their particular natures, depend on the general system of the great whole, or that Universal Nature, of which they form a part; to which every thing that exists is necessarily submitted and attached.
Having described the proper definition that should be applied to the word NATURE, I must advise the reader, once for all, that whenever in the course of this work the expression occurs, that "Nature produces such or such an effect," there is no intention of personifying that nature which is purely an abstract being; it merely indicates that the effect spoken of necessarily springs from the peculiar properties of those beings which compose the mighty macrocosm. When, therefore, it is said, Nature demands that man should pursue his own happiness, it is to prevent circumlocution—to avoid tautology; it is to be understood, that it is the property of a being that feels, that thinks, that acts, to labour to its own happiness; in short, that is called natural, which is conformable to the essence of things, or to the laws, which Nature prescribes to the beings she contains, in the different orders they occupy, under the various circumstances through which they are obliged to pass. Thus health is natural to man in a certain state; disease is natural to him under other circumstances; dissolution, or if they will, death, is a natural state for a body, deprived of some of those things, necessary to maintain the existence of the animal, &c. By ESSENCE is to be understood, that which constitutes a being, such as it is; the whole of the properties or qualities by which it acts as it does. Thus, when it is said, it is the essence of a stone to fall, it is the same as saying that its descent is the necessary effect of its gravity—of its density—of the cohesion of its parts—of the elements of which it is composed. In short, the essence of a being is its particular, its individual nature.
CHAP. II.
Of Motion, and its Origin.
Motion is an effect by which a body either changes, or has a tendency to change, its position: that is to say, by which it successively corresponds with different parts of space, or changes its relative distance to other bodies. It is motion alone that establishes the relation between our senses and exterior or interior beings: it is only by motion that these beings are impressed upon us—that we know their existence—that we judge of their properties—that we distinguish the one from the other—that we distribute them into classes.
The beings, the substances, or the various bodies of which Nature is the assemblage, are themselves effects of certain combinations or causes which become causes in their turn. A CAUSE is a being which puts another in motion, or which produces some change in it. The EFFECT is the change produced in one body, by the motion or presence of another.
Each being, by its essence, by its peculiar nature, has the faculty of producing, is capable of receiving, has the power of communicating, a variety of motion. Thus some beings are proper to strike our organs; these organs are competent to receiving the impression, are adequate to undergoing changes by their presence. Those which cannot act on any of our organs, either immediately and by themselves, or immediately by the intervention of other bodies, exist not for us; since they can neither move us, nor consequently furnish us with ideas: they can neither be known to us, nor of course be judged of by us. To know an object, is to have felt it; to feel it, it is requisite to have been moved by it. To see, is to have been moved, by something acting on the visual organs; to hear, is to have been struck, by something on our auditory nerves. In short, in whatever mode a body may act upon us, whatever impulse we may receive from it, we can have no other knowledge of it than by the change it produces in us.
Nature, as we have already said, is the assemblage of all the beings, consequently of all the motion of which we have a knowledge, as well as of many others of which we know nothing, because they have not yet become accessible to our senses. From the continual action and re-action of these beings, result a series of causes and effects; or a chain of motion guided by the constant and invariable laws peculiar to each being; which are necessary or inherent to its particular nature—which make it always act or move after a determinate manner. The different principles of this motion are unknown to us, because we are in many instances, if not in all, ignorant of what constitutes the essence of beings. The elements of bodies escape our senses; we know them only in the mass: we are neither acquainted with their intimate combination, nor the proportion of these combinations; from whence must necessarily result their mode of action, their impulse, or their different effects.
Our senses bring us generally acquainted with two sorts of motion in the beings that surround us: the one is the motion of the mass, by which an entire body is transferred from one place to another. Of the motion of this genus we are perfectly sensible.—Thus, we see a stone fall, a ball roll, an arm move, or change its position. The other is an internal or concealed motion, which always depends on the peculiar energies of a body: that is to say, on its essence, or the combination, the action, and re-action of the minute—of the insensible particles of matter, of which that body is composed. This motion we do not see; we know it only by the alteration or change, which after some time we discover in these bodies or mixtures. Of this genus is that concealed motion which fermentation produces in the particles that compose flour, which, however scattered, however separated, unite, and form that mass which we call BREAD. Such also is the imperceptible motion by which we see a plant or animal enlarge, strengthen, undergo changes, and acquire new qualities, without our eyes being competent to follow its progression, or to perceive the causes which have produced these effects. Such also is the internal motion that takes place in man, which is called his INTELLECTUAL FACULTIES, his THOUGHTS, his PASSIONS, his will. Of these we have no other mode of judging, than by their action; that is, by those sensible effects which either accompany or follow them. Thus, when we see a man run away, we judge him to be interiorly actuated by the passion of fear.
Motion, whether visible or concealed, is styled ACQUIRED, when it is impressed on one body by another; either by a cause to which we are a stranger, or by an exterior agent which our senses enable us to discover. Thus we call that acquired motion, which the wind gives to the sails of a ship. That motion which is excited in a body, that contains within itself the causes of those changes we see it undergo, is called SPONTANEOUS. Then it is said, this body acts or moves by its own peculiar energies. Of this kind is the motion of the man who walks, who talks, who thinks. Nevertheless, if we examine the matter a little closer, we shall be convinced, that, strictly speaking, there is no such thing as spontaneous motion in any of the various bodies of Nature; seeing they are perpetually acting one upon the other; that all their changes are to be attributed to the causes, either visible or concealed, by which they are moved. The will of man is secretly moved or determined by some exterior cause that produces a change in him: we believe he moves of himself, because we neither see the cause that determined him, the mode in which it acted, nor the organ that it put in motion.
That is called SIMPLE MOTION, which is excited in a body by a single cause. COMPOUND MOTION, that which is produced by two or more different causes; whether these causes are equal or unequal, conspiring differently, acting together or in succession, known or unknown.
Let the motion of beings be of whatsoever nature it may, it is always the necessary consequence of their essence, or of the properties which compose them, and of those causes of which they experience the action. Each being can only move and act after a particular manner; that is to say, conformably to those laws which result from its peculiar essence, its particular combination, its individual nature: in short, from its specific energies, and those of the bodies from which it receives an impulse. It is this that constitutes the invariable laws of motion: I say invariable, because they can never change, without producing confusion in the essence of things. It is thus that a heavy body must necessarily fall, if it meets with no obstacle sufficient to arrest its descent; that a sensible body must naturally seek pleasure, and avoid pain; that fire must necessarily burn, and diffuse light.
Each being, then, has laws of motion, that are adapted to itself, and constantly acts or moves according to these laws; at least when no superior cause interrupts its action. Thus, fire ceases to burn combustible matter, as soon as sufficient water is thrown into it, to arrest its progress. Thus, a sensible being ceases to seek pleasure, as soon as he fears that pain will be the result.
The communication of motion, or the medium of action, from one body to another, also follows certain and necessary laws; one being can only communicate motion to another, by the affinity, by the resemblance, by the conformity, by the analogy, or by the point of contact, which it has with that other being. Fire can only propagate when it finds matter analogous to itself: it extinguishes when it encounters bodies which it cannot embrace; that is to say, that do not bear towards it a certain degree of relation or affinity.
Every thing in the universe is in motion: the essence of matter is to act: if we consider its parts, attentively, we shall discover there is not a particle that enjoys absolute repose. Those which appear to us to be without motion, are, in fact, only in relative or apparent rest; they experience such an imperceptible motion, and expose it so little on their surfaces, that we cannot perceive the changes they undergo. All that appears to us to be at rest, does not, however, remain one instant in the same state. All beings are continually breeding, increasing, decreasing, or dispersing, with more or less dullness or rapidity. The insect called EPHEMERON, is produced and perishes in the same day; of consequence, it experiences the greatest changes of its being very rapidly, in our eyes. Those combinations which form the most solid bodies, which appear to enjoy the most perfect repose, are nevertheless decomposed, and dissolved in the course of time. The hardest stones, by degrees, give way to the contact of air. A mass of iron, which time, and the action of the atmosphere, has gnawed into rust, must have been in motion, from the moment of its formation, in the bowels of the earth, until the instant we behold it in this state of dissolution.
Natural philosophers, for the most part, seem not to have sufficiently reflected on what they call the nisus; that is to say, the incessant efforts one body is making on another, but which, notwithstanding appear, to our superficial observation, to enjoy the most perfect repose. A stone of five hundred weight seems to rest quiet on the earth, nevertheless, it never ceases for an instant, to press with force upon the earth, which resists or repulses it in its turn. Will the assertion be ventured, that the stone and earth do not act? Do they wish to be undeceived? They have nothing to do but interpose their hand betwixt the earth and the stone; it will then be discovered, that notwithstanding its seeming repose, the stone has power adequate to bruise it; because the hand has not energies sufficient, within itself, to resist effectually both the stone and earth.—Action cannot exist in bodies without re-action. A body that experiences an impulse, an attraction, or a pressure of any kind, if it resists, clearly demonstrates by such resistance that it re-acts; from whence it follows, there is a concealed force, called by these philosophers vis inertia, that displays itself against another force; and this clearly demonstrates, that this inert force is capable of both acting and re-acting. In short, it will be found, on close investigation, that those powers which are called dead, and those which are termed live or moving, are powers of the same kind; which only display themselves after a different manner. Permit us to go a greater distance yet. May we not say, that in those bodies, or masses, of which their whole become evident from appearances to us to be at rest, there is notwithstanding, a continual action, and counter-action, constant efforts, uninterrupted or communicated force, and continued opposition? In short, a nisus, by which the constituting portions of these bodies press one upon another, mutually resisting each other, acting and re-acting incessantly? that this reciprocity of action, this simultaneous re-action, keeps them united, causes their particles to form a mass, a body, and a combination, which, viewed in its whole, has the appearance of complete rest, notwithstanding no one of its particles really ceases to be in motion for a single instant? These collective masses appear to be at rest, simply by the equality of the motion—by the responsory impulse of the powers acting in them.
Thus it appears that bodies enjoying perfect repose, really receive, whether upon their surface, or in their interior, a continual communicated force, from those bodies by which they are either surrounded or penetrated, dilated or contracted, rarified or condensed: in fact, from those which compose them; whereby their particles are incessantly acting and re-acting, or in continual motion, the effects of which are displayed by extraordinary changes. Thus heat rarifies and dilates metals, which is evidence deducible that a bar of iron, from the change of the atmosphere alone, must be in continual motion; that there is not a single particle in it that can be said to enjoy rest even for a single moment. In those hard bodies, indeed, the particles of which are in actual contact, and which are closely united, how is it possible to conceive, that air, cold, or heat, can act upon one of these particles, even exteriorly, without the motion being communicated to those which are most intimate and minute in their union? Without motion, how should we be able to comprehend the manner in which our sense of smelling is affected, by emanations escaping from the most solid bodies, of which all the particles appear to be at perfect rest? How could we, even by the assistance of a telescope, see the most distant stars, if there was not a progressive motion of light from these stars to the retina of our eye?
Observation and reflection ought to convince us, that every thing in Nature is in continual motion—that there is not a single part, however small, that enjoys repose—that Nature acts in all—that she would cease to be Nature if she did not act. Practical knowledge teaches us, that without unceasing motion, nothing could be preserved—nothing could be produced—nothing could act in this Nature. Thus the idea of Nature necessarily includes that of motion. But it will be asked, and not a little triumphantly, from whence did she derive her motion? Our reply is, we know not, neither do they—that we never shall, that they never will. It is a secret hidden from us, concealed from them, by the most impenetrable veil. We also reply, that it is fair to infer, unless they can logically prove to the contrary, that it is in herself, since she is the great whole, out of which nothing can exist. We say this motion is a manner of existence, that flows, necessarily, out of the nature of matter; that matter moves by its own peculiar energies; that its motion is to be attributed to the force which is inherent in itself; that the variety of motion, and the phenomena which result, proceed from the diversity of the properties—of the qualities—of the combinations, which are originally found in the primitive matter, of which Nature is the assemblage.
Natural philosophers, for the most part, have regarded as inanimate, or as deprived of the faculty of motion, those bodies which are only moved by the intervention of some agent or exterior cause; they have considered themselves justified in concluding, that the matter which forms these bodies is perfectly inert in its nature. They have not forsaken this error, although they must have observed, that whenever a body is left to itself, or disengaged from those obstructions which oppose themselves to its descent, it has a tendency to fall or to approach the centre of the earth, by a motion uniformly accelerated; they have rather chosen to suppose a visionary exterior cause, of which they themselves had but an imperfect idea, than admit that these bodies held their motion from their own peculiar nature.
These philosophers, also, notwithstanding they saw above them an infinite number of globes that moved with great rapidity round a common centre, still adhered to their favourite opinions; and never ceased to suppose some whimsical causes for these movements, until the immortal NEWTON clearly demonstrated that it was the effect of the gravitation of these celestial bodies towards each other. Experimental philosophers, however, and amongst them the great Newton himself, have held the cause of gravitation as inexplicable. Notwithstanding the great weight of this authority, it appears manifest that it may be deduced from the motion of matter, by which bodies are diversely determined. Gravitation is nothing more than a mode of moving—a tendency towards a centre: to speak strictly, all motion is relative gravitation; since that which falls relatively to us, rises, with relation to other bodies. From this it follows, that every motion in our microcosm is the effect of gravitation; seeing that there is not in the universe either top or bottom, nor any absolute centre. It should appear, that the weight of bodies depends on their configuration, as well external as internal, which gives them that form of action which is called gravitation. Thus, for instance, a piece of lead, spherically formed, falls quickly and direct: reduce this ball into very thin plates, it will be sustained in the air for a much longer time: apply to it the action of fire, this lead will rise in the atmosphere: here, then, the same metal, variously modified, has very different modes of action.
A very simple observation would have sufficed to make the philosophers, antecedent to Newton, feel the inadequateness of the causes they admitted to operate with such powerful effect. They had a sufficiency to convince themselves, in the collision of two bodies, which they could contemplate, and in the known laws of that motion, which these always communicate by reason of their greater or less compactness; from whence they ought to have inferred, that the density of subtle or ethereal matter, being considerably less than that of the planets, it could only communicate to them a very feeble motion, quite insufficient to produce that velocity of action, of which they could not possibly avoid being the witnesses.
If Nature had been viewed uninfluenced by prejudice, they must have been long since convinced that matter acts by its own peculiar activity; that it needs no exterior communicative force to set it in motion. They might have perceived that whenever mixed bodies were placed in a situation to act on each other, motion was instantly excited; and that these mixtures acted with a force capable of producing the most surprising results.
If particles of iron, sulphur, and water be mixed together, these bodies thus capacitated to act on each other, are heated by degrees, and ultimately produce a violent combustion. If flour be wetted with water, and the mixture closed up, it will be found, after some lapse of time, (by the aid of a microscope) to have produced organized beings that enjoy life, of which the water and the flour were believed incapable: it is thus that inanimate matter can pass into life, or animate matter, which is in itself only an assemblage of motion.
Reasoning from analogy, which the philosophers of the present day do not hold incompatible, the production of a man, independent of the ordinary means, would not be more astonishing than that of an insect with flour and water. Fermentation and putrid substances, evidently produce living animals. We have here the principle; with proper materials, principles can always be brought into action. That generation which is styled uncertain is only so for those who do not reflect, or who do not permit themselves, attentively, to observe the operations of Nature.
The generative of motion, and its developement, as well as the energy of matter, may be seen everywhere; more particularly in those unitions in which fire, air, and water, find themselves combined. These elements, or rather these mixed bodies, are the most volatile, the most fugitive of beings; nevertheless in the hands of Nature, they are the essential agents employed to produce the most striking phenomena. To these we must ascribe the effects of thunder, the eruption of volcanoes, earthquakes, &c. Science offers to our consideration an agent of astonishing force, in gunpowder, the instant it comes in contact with fire. In short, the most terrible effects result from the combination of matter, which is generally believed to be dead and inert.
These facts prove, beyond a doubt, that motion is produced, is augmented, is accelerated in matter, without the help of any exterior agent: therefore it is reasonable to conclude that motion is the necessary consequence of immutable laws, resulting from the essence, from the properties existing in the different elements, and the various combinations of these elements. Are we not justified, then, in concluding, from these precedents, that there may be an infinity of other combinations, with which we are unacquainted, competent to produce a great variety of motion in matter, without being under the necessity of having recourse, for the explanation, to agents who are more difficult to comprehend than even the effects which are attributed to them?
Had man but paid proper attention to what passed under his review, he would not have sought out of Nature, a power distinguished from herself, to set her in action, and without which he believes she cannot move. If, indeed, by Nature is meant a heap of dead matter, destitute of peculiar qualities purely passive, we must unquestionably seek out of this Nature the principle of her motion. But if by Nature be understood, what it really is, a whole, of which the numerous parts are endowed with various properties, which oblige them to act according to these properties; which are in a perpetual ternateness of action and reaction; which press, which gravitate towards a common center, whilst others depart from and fly off towards the periphery, or circumference; which attract and repel; which by continual approximation and constant collision, produce and decompose all the bodies we behold; then, I say, there is no necessity to have recourse to supernatural powers, to account for the formation of things, and those extraordinary appearances which are the result of motion.
Those who admit a cause exterior to matter, are obliged to believe that this cause produced all the motion by which matter is agitated in giving it existence. This belief rests on another, namely, that matter could begin to exist; an hypothesis that, until this moment, has never been satisfactorily demonstrated. To produce from nothing, or the CREATION, is a term that cannot give us the least idea of the formation of the universe; it presents no sense, upon which the mind can rely. In fact, the human mind is not adequate to conceive a moment of non-existence, or when all shall have passed away; even admitting this to be a truth, it is no truth for us, because by the very nature of our organization, we cannot admit positions as facts, of which no evidence can be adduced that has relation to our senses; we may, indeed, consent to believe it, because others say it; but will any rational being be satisfied with such an admission? Can any moral good spring from such blind assurance? Is it consistent with sound doctrine, with philosophy, or with reason? Do we, in fact, pay any respect to the intellectual powers of another, when we say to him, "I will believe this, because in all the attempts you have ventured, for the purpose of proving what you say, you have entirely failed; and have been at last obliged to acknowledge you know nothing about the matter?" What moral reliance ought we to have on such people? Hypothesis may succeed hypothesis; system may destroy system: a new set of ideas may overturn the ideas of a former day. Other Gallileos may be condemned to death—other Newtons may arise—we may reason—argue—dispute—quarrel—punish and destroy: nay, we may even exterminate those who differ from us in opinion; but when we have done all this, we shall be obliged to fall back upon our original darkness—to confess, that that which has no relation with our senses, that which cannot manifest itself to us by some of the ordinary modes by which other things are manifested, has no existence for us—is not comprehensible by us—can never entirely remove our doubt—can never seize on our stedfast belief; seeing it is that of which we cannot form even a notion; in short, that it is that, which as long as we remain what we are, must be hidden from us by a veil, which no power, no faculty, no energy we possess, is able to remove. All who are not enslaved by prejudice agree to the truth of the position, that nothing can be made of nothing. Many theologians have acknowledged Nature to be an active whole. Almost all the ancient philosophers were agreed to regard the world as eternal. OCELLUS LUCANUS, speaking of the universe, says, "it has always been, and it always will be." VATABLE and GROTIUS assure us, that to render the Hebrew phrase in the first chapter of GENESIS correctly, we must say, "when God made heaven and earth, matter was without form." If this be true, and every Hebraist can judge for himself, then the word which has been rendered created, means only to fashion, form, arrange. We know that the Greek words create and form, have always indicated the same thing. According to ST. JEROME, creare has the same meaning as condere, to found, to build. The Bible does not anywhere say in a clear manner, that the world was made of nothing. TERTULLIAN and the father PETAU both admit, that "this is a truth established more by reason than by authority." ST. JUSTIN seems to have contemplated matter as eternal, since he commends PLATO for having said, that "God, in the creation of the world, only gave impulse to matter, and fashioned it." BURNET and PYTHAGORAS were entirely of this opinion, and even our Church Service may be adduced in support; for although it admits by implication a beginning, it expressly denies an end: "As it was in the beginning, is now, and ever shall be, world without end." It is easy to perceive that that which cannot cease to exist, must have always been.
Motion becomes still more obscure, when creation, or the formation of matter, is attributed to a SPIRITUAL being; that is to say, to a being which has no analogy, no point of contact, with it—to a being which has neither extent or parts, and cannot, therefore, be susceptible of motion, as we understand the term; this being only the change of one body, relatively to another body, in which the body moved presents successively different parts to different points of space. Moreover, as all the world are nearly agreed that matter can never be totally annihilated, or cease to exist; by what reasoning, I would ask, do they comprehend—how understand—that that which cannot cease to be, could ever have had a beginning?
If, therefore, it be asked, whence came matter? it is very reasonable to say it has always existed. If it be inquired, whence proceeds the motion that agitates matter? the same reasoning furnishes the answer; namely, that as motion is coeval with matter, it must have existed from all eternity, seeing that motion is the necessary consequence of its existence—of its essence—of its primitive properties, such as its extent, its gravity, its impenetrability, its figure, &c. By virtue of these essential constituent properties, inherent in all matter, and without which it is impossible to form an idea of it, the various matter of which the universe is composed must from all eternity have pressed against, each other—have gravitated towards a center—have clashed—have come in contact—have been attracted—have been repelled—have been combined—have been separated: in short, must have acted and moved according to the essence and energy peculiar to each genus, and to each of its combinations.
Existence supposes properties in the thing that exists: whenever it has properties, its mode of action must necessarily flow from those properties which constitute, its mode of being. Thus, when a body is ponderous, it must fall; when it falls, it must come in collision with the bodies it meets in its descent; when it is dense, when it is solid, it must, by reason of this density, communicate motion to the bodies with which it clashes; when it has analogy, when it has affinity with these bodies, it must be attracted, must be united with them; when it has no point of analogy with them, it must be repulsed.
From which it may be fairly inferred, that in supposing, as we are under the necessity of doing, the existence of matter, we must suppose it to have some kind of properties; from which its motion, or modes of action, must necessarily flow. To form the universe, DESCARTES asked but matter and motion: a diversity of matter sufficed for him; variety of motion was the consequence of its existence, of its essence, of its properties: its different modes of action would be the necessary consequence of its different modes of being. Matter without properties would be a mere nothing; therefore, as soon as matter exists, it must act; as soon as it is various, it must act variously; if it cannot commence to exist, it must have existed from all eternity; if it has always existed, it can never cease to be: if it can never cease to be, it can never cease to act by its own energy. Motion is a manner of being, which matter derives from its peculiar existence.
The existence, then, of matter is a fact: the existence of motion is another fact. Our visual organs point out to us matter with different essences, forming a variety of combinations, endowed with various properties that discriminate them. Indeed, it is a palpable error to believe that matter is a homogeneous body, of which the parts differ from each other only by their various modifications. Among the individuals of the same species that come under our notice, no two resemble exactly; and it is therefore evident that the difference of situation alone will, necessarily, carry a diversity more or less sensible, not only in the modifications, but also in the essence, in the properties, in the entire system of beings. This truth was well understood by the profound and subtle LEIBNITZ.
If this principle be properly digested, and experience seems always to produce evidence of its truth, we must be convinced that the matter or primitive elements which enter into the composition of bodies, are not of the same nature, and consequently, can neither have the same properties, nor the same modifications; and if so, they cannot have the same mode of moving and acting. Their activity or motion, already different, can be diversified to infinity, augmented or diminished, accelerated or retarded, according to the combinations, the proportions, the pressure, the density, the volume of the matter, that enters their composition. The endless variety to be produced, will need no further illustration than the commonest book of arithmetic furnishes us, where it will be found, that to ring all the changes that can be produced on twelve bells only, would occupy a space of more than ninety-one years. The element of fire is visibly more active and more inconstant than that of earth. This is more solid and ponderous than fire, air, or water. According to the quantity of these elements, which enter the composition of bodies, these must act diversely, and their motion must in some measure partake the motion peculiar to each of their constituent parts. Elementary fire appears to be in Nature the principle of activity; it may be compared to a fruitful leaven, that puts the mass into fermentation and gives it life. Earth appears to be the principle of solidity in bodies, from its impenetrability, and by the firm coherence of its parts. Water is a medium, to facilitate the combination of bodies, into which it enters itself, as a constituent part. Air is a fluid whose business it seems to be, to furnish the other elements with the space requisite to expand, to exercise their motion, and which is, moreover, found proper to combine with them. These elements, which our senses never discover in a pure state—which are continually and reciprocally set in motion by each other—which are always acting and re-acting, combining and separating, attracting and repelling—are sufficient to explain to us the formation of all the beings we behold. Their motion is uninterruptedly and reciprocally produced from each other; they are alternately causes and effects. Thus, they form a vast circle of generation and destruction—of combination and decomposition, which, it is quite reasonable to suppose, could never have had a beginning, and which, consequently can never have an end. In short, Nature is but an immense chain of causes and effects, which unceasingly flow from each other. The motion of particular beings depends on the general motion, which is itself maintained by individual motion. This is strengthened or weakened, accelerated or retarded, simplified or complicated, procreated or destroyed, by a variety of combinations and circumstances, which every moment change the directions, the tendency, the modes of existing, and of acting, of the different beings that receive its impulse.
If it were true, as has been asserted by some philosophers, that every thing has a tendency to form one unique or single mass, and in that unique mass the instant should arrive when all was in nisus, all would eternally remain in this state; to all eternity there would be no more than one Being and one effort: this would be eternal and universal death.
If we desire to go beyond this, to find the principle of action in matter, to trace the origin of things, it is for ever to fall back upon difficulties; it is absolutely to abridge the evidence of our senses; by which only we can understand, by which alone we can judge of the causes acting upon them, or the impulse by which they are set in action.
Let us, therefore, content ourselves with saying WHAT is supported by our experience, and by all the evidence we are capable of understanding; against the truth of which not a shadow of proof, such as our reason can admit, has ever been adduced—which has been maintained by philosophers in every age—which theologians themselves have not denied, but which many of them have upheld; namely, that matter always existed; that it moves by virtue of its essence; that all the phenomena of Nature is ascribable to the diversified motion of the variety of matter she contains; and which, like the phoenix, is continually regenerating out of its own ashes.
CHAP. III.
Of Matter.—Of its various Combinations.—Of its diversified Motion, or of the Course of Nature.
We know nothing of the elements of bodies, but we know some of their properties or qualities; and we distinguish their various matter by the effect or change produced on our senses; that is to say, by the variety of motion their presence excites in us. In consequence, we discover in them, extent, mobility, divisibility, solidity, gravity, and inert force. From these general and primitive properties flow a number of others, such as density, figure, colour, ponderosity, &c. Thus, relatively to us, matter is all that affects our senses in any manner whatever; the various properties we attribute to matter, by which we discriminate its diversity, are founded on the different impressions we receive on the changes they produce in us.
A satisfactory definition of matter has not yet been given. Man, deceived and led astray by his prejudices, formed but vague, superficial, and imperfect notions concerning it. He looked upon it as an unique being, gross and passive, incapable of either moving by itself, of forming combinations, or of producing any thing by its own energies. Instead of this unintelligible jargon, he ought to have contemplated it as a genus of beings, of which the individuals, although they might possess some common properties, such as extent, divisibility, figure, &c. should not, however, be all ranked in the same class, nor comprised under the same general denomination.
An example will serve more fully to explain what we have asserted, throw its correctness into light, and facilitate the application. The properties common to all matter, are extent, divisibility, impenetrability, figure, mobility, or the property of being moved in mass. FIRE, beside these general properties, common to all matter, enjoys also the peculiar property of being put into activity by a motion that produces on our organs of feeling the sensation of heat; and by another, that communicates to our visual organs the sensation of light. Iron, in common with matter in general, has extent and figure; is divisible, and moveable in mass: if fire be combined with it in a certain proportion, the iron acquires two new properties; namely, those of exciting in us similar sensations of heat and light, which were excited by the element of fire, but which the iron had not, before its combination with the igneous matter. These distinguishing properties are inseparable from matter, and the phenomena that result, may, in the strictest sense of the word, be said to result necessarily.
If we contemplate a little the paths of Nature—if, for a time, we trace the beings in this Nature, under the different states through which, by reason of their properties, they are compelled to pass; we shall discover, that it is to motion, and motion only, that is to be ascribed all the changes, all the combinations, all the forms, in short, all the various modifications of matter. That it is by motion every thing that exists is produced, experiences change, expands, and is destroyed. It is motion that alters the aspect of beings; that adds to, or takes away from their properties; which obliges each of them, by a consequence of its nature, after having occupied a certain rank or order, to quit it, to occupy another, and to contribute to the generation, maintenance, and decomposition of other beings, totally different in their bulk, rank, and essence.
In what experimental philosophers have styled the THREE ORDERS OF NATURE, that is to say, the mineral, the vegetable, and animal worlds, they have established, by the aid of motion, a transmigration, an exchange, a continual circulation in the particles of matter. Nature has occasion in one place, for those particles which, for a time, she has placed in another. These particles, after having, by particular combinations, constituted beings endued with peculiar essences, with specific properties, with determinate modes of action, dissolve and separate with more or less facility; and combining in a new manner, they form new beings. The attentive observer sees this law execute itself, in a manner more or less prominent, through all the beings by which he is surrounded. He sees nature full of erratic germe, some of which expand themselves, whilst others wait until motion has placed them in their proper situation, in suitable wombs or matrices, in the necessary circumstances, to unfold, to increase, to render them more perceptible by the addition of other substances of matter analogous to their primitive being. In all this we see nothing but the effect of motion, necessarily guided, modified, accelerated or slackened, strengthened or weakened, by reason of the various properties that beings successively acquire and lose; which, every moment, infallibly produces alterations in bodies more or less marked. Indeed, these bodies cannot be, strictly speaking, the same in any two successive moments of their existence; they must, every instant, either acquire or lose: in short, they are obliged to undergo continual variations in their essences, in their properties, in their energies, in their masses, in their qualities, in their mode of existence.
Animals, after they have been expanded in, and brought out of, the wombs that are suitable to the elements of their machine, enlarge, strengthen, acquire new properties, new energies, new faculties; either by deriving nourishment from plants analogous to their being, or by devouring other animals whose substance is suitable to their preservation; that is to say, to repair the continual deperdition or loss of some portion of their own substance, that is disengaging itself every instant. These same animals are nourished, preserved, strengthened, and enlarged, by the aid of air, water, earth, and fire. Deprived of air, or of the fluid that surrounds them, that presses on them, that penetrates them, that gives them their elasticity, they presently cease to live. Water, combined with this air, enters into their whole mechanism of which it facilitates the motion. Earth serves them for a basis, by giving solidity to their texture: it is conveyed by air and water, which carry it to those parts of the body with which it can combine. Fire itself, disguised and enveloped under an infinity of forms, continually received into the animal, procures him heat, continues him in life, renders him capable of exercising his functions. The aliments, charged with these various principles, entering into the stomach, re-establish the nervous system, and restore, by their activity, and the elements which compose them, the machine which begins to languish, to be depressed, by the loss it has sustained. Forthwith the animal experiences a change in his whole system; he has more energy, more activity; he feels more courage; displays more gaiety; he acts, he moves, he thinks, after a different manner; all his faculties are exercised with more ease. This igneous matter, so congenial to generation—so restorative in its effect—so necessary to life, was the JUPITER of the ancients: from all that has preceded, it is clear, that what are called the elements, or primitive parts of matter, variously combined, are, by the agency of motion, continually united to, and assimilated with, the substance of animals—that they visibly modify their being—have an evident influence over their actions, that is to say, upon the motion they undergo, whether visible or concealed.
The same elements, which under certain circumstances serve to nourish, to strengthen, to maintain the animal, become, under others, the principles of his weakness, the instruments of his dissolution—of his death: they work his destruction, whenever they are not in that just proportion which renders them proper to maintain his existence: thus, when water becomes too abundant in the body of the animal, it enervates him, it relaxes the fibres, and impedes the necessary action of the other elements: thus, fire admitted in excess, excites in him disorderly motion destructive of his machine: thus, air, charged with principles not analogous to his mechanism, brings upon him dangerous diseases and contagion. In fine, the aliments modified after certain modes, in the room of nourishing, destroy the animal, and conduce to his ruin: the animal is preserved no longer than these substances are analogous to his system. They ruin him when they want that just equilibrium that renders them suitable to maintain his existence.
Plants that serve to nourish and restore animals are themselves nourished by earth; they expand on its bosom, enlarge and strengthen at its expense, continually receiving into their texture, by their roots and their pores, water, air, and igneous matter: water visibly reanimates them whenever their vegetation or genus of life languishes; it conveys to them those analogous principles by which they are enabled to reach perfection: air is requisite to their expansion, and furnishes them with water, earth, and the igneous matter with which it is charged. By these means they receive more or less of the inflammable matter; the different proportions of these principles, their numerous combinations, from whence result an infinity of properties, a variety of forms, constitute the various families and classes into which botanists have distributed plants: it is thus we see the cedar and the hyssop develop their growth; the one rises to the clouds, the other creep humbly on the earth. Thus, by degrees, from an acorn springs the majestic oak, accumulating, with time, its numerous branches, and overshadowing us with its foliage. Thus, a grain of corn, after having drawn its own nourishment from the juices of the earth, serves, in its turn, for the nourishment of man, into whose system it conveys the elements or principles by which it has been itself expanded, combined, and modified in such a manner, as to render this vegetable proper to assimilate and unite with the human frame; that is to say, with the fluids and solids of which it is composed.
The same elements, the same principles, are found in the formation of minerals, as well as in their decomposition, whether natural or artificial. We find that earth, diversely modified, wrought, and combined, serves to increase their bulk, and give them more or less density and gravity. Air and water contribute to make their particles cohere; the igneous matter, or inflammable principle, tinges them with colour, and sometimes plainly indicates its presence, by the brilliant scintillation which motion elicits from them. These stones and metals, these bodies, so compact and solid, are disunited, are destroyed, by the agency of air, water, and fire; which the most ordinary analysis is sufficient to prove, as well as a multitude of experience, to which our eyes are the daily evidence.
Animals, plants, and minerals, after a lapse of time, give back to Nature; that is to say, to the general mass of things, to the universal magazine, the elements, or principles, which they have borrowed: The earth retakes that portion of the body of which it formed the basis and the solidity; the air charges itself with these parts, that are, analogous to it, and with those particles which are light and subtle; water carries off that which is suitable to liquescency; fire, bursting its chains, disengages itself, and rushes into new combinations with other bodies.
The elementary particles of the animal, being thus dissolved, disunited, and dispersed; assume new activity, and form new combinations: thus, they serve to nourish, to preserve, or destroy new beings; among others, plants, which arrived at their maturity, nourish and preserve new animals; these in their turn yielding to the same fate as the first.
Such is the constant, the invariable course, of Nature; such is the eternal circle of mutation, which all that exists is obliged to describe. It is thus motion generates, preserves for a time, and successively, destroys, one part of the universe by the other; whilst the sum of existence remains eternally the same. Nature, by its combinations, produces suns, which place themselves in the centre of so many systems: she forms planets, which, by their peculiar essence, gravitate and describe their revolutions round these suns: by degrees the motion is changed altogether, and becomes eccentric: perhaps the day may arrive when these wondrous masses will disperse, of which man, in the short space of his existence, can only have a faint and transient glimpse.
It is clear, then, that the continual motion inherent in matter, changes and destroys all beings; every instant depriving them of some of their properties, to substitute others: it is motion, which, in thus changing their actual essence, changes also their order, their direction, their tendency, and the laws which regulate their mode of acting and being: from the stone formed in the bowels of the earth, by the intimate combination and close coherence of similar and analogous particles, to the sun, that vast reservoir of igneous particles, which sheds torrents of light over the firmament; from the benumbed oyster, to the thoughtful and active man; we see an uninterrupted progression, a perpetual chain of motion and combination; from which is produced, beings that only differ from each other by the variety of their elementary matter—by the numerous combinations of these elements, from whence springs modes of action and existence, diversified to infinity. In generation, in nutrition, in preservation, we see nothing more than matter, variously combined, of which each has its peculiar motion, regulated by fixed and determinate laws, which oblige them to submit to necessary changes. We shall find, in the formation, in the growth, in the instantaneous life, of animals, vegetables, and minerals, nothing but matter; which combining, accumulating, aggregating, and expanding by degrees, forms beings, who are either feeling, living, vegetating, or else destitute of these faculties; which, having existed some time under one particular form, are obliged to contribute by their ruin to the production of other forms.
Thus, to speak strictly, nothing in Nature is either born, or dies, according to the common acceptation of those terms. This truth was felt by many of the ancient philosophers. PLATO says, that according to tradition, "the living were born of the dead, the same as the dead did come of the living; and that this is the constant routine of Nature." He adds from himself, "who knows, if to live, be not to die; and if to die, be not to live?" This was the doctrine of PYTHAGORAS, a man of great talent and no less note. EMPEDOCLES asserts, "there is neither birth nor death, for any mortal; but only a combination, and a separation of that which was combined, and that this is what amongst men they call birth, and death." Again he remarks, "those are infants, or short-sighted persons, with very contracted understandings, who imagine any thing is born, which did not exist before, or that any thing can die or perish totally."
CHAP. IV.
Laws of Motion, common to every Being of Nature.—Attraction and Repulsion.—Inert Force.—Necessity.
Man is never surprised at those effects, of which he thinks he knows the cause; he believes he does know the cause, as soon as he sees them act in an uniform and determinate manner, or when the motion excited is simple: the descent of a stone, that falls by its own peculiar weight, is an object of contemplation to the philosopher only; to whom the mode by which the most immediate causes act, and the most simple motion, are no less impenetrable mysteries than the most complex motion, and the manner by which the most complicated causes give impulse. The uninformed are seldom tempted either to examine the effects which are familiar to them, or to recur to first principles. They think they see nothing in the descent of a stone, which ought to elicit their surprise, or become the object of their research: it requires a NEWTON to feel that the descent of heavy bodies is a phenomenon, worthy his whole, his most serious attention; it requires the sagacity of a profound experimental philosopher, to discover the laws by which heavy bodies fall, by which they communicate to others their peculiar motion. In short, the mind that is most practised in philosophical observation, has frequently the chagrin to find, that the most simple and most common effects escape all his researches, and remain inexplicable to him.
When any extraordinary, any unusual, effect is produced, to which our eyes have not been accustomed; or when we are ignorant of the energies of the cause, the action of which so forcibly strikes our senses, we are tempted to meditate upon it, and take it into our consideration. The European, accustomed to the use of GUNPOWDER, passes it by, without thinking much of its extraordinary energies; the workman, who labours to manufacture it, finds nothing marvellous in its properties, because he daily handles the matter that forms its composition. The American, to whom this powder was a stranger, who had never beheld its operation, looked upon it as a divine power, and its energies as supernatural. The uninformed, who are ignorant of the true cause of THUNDER, contemplate it as the instrument of divine vengeance. The experimental philosopher considers it as the effect of the electric matter, which, nevertheless, is itself a cause which he is very far from perfectly understanding.—It required the keen, the penetrating mind of a FRANKLIN, to throw light on the nature of this subtle fluid—to develop the means by which its effects might be rendered harmless—to turn to useful purposes, a phenomenon that made the ignorant tremble—that filled their minds with terror, their hearts with dismay, as indicating the anger of the gods: impressed with this idea, they prostrated themselves, they sacrificed to JUPITER, to deprecate his wrath.
Be this as it may, whenever we see a cause act, we look upon its effect as natural: when this cause becomes familiar to the sight, when we are accustomed to it, we think we understand it, and its effects surprise us no longer. Whenever any unusual effect is perceived, without our discovering the cause, the mind sets to work, becomes uneasy; this uneasiness increases in proportion to its extent: as soon as it is believed to threaten our preservation, we become completely agitated; we seek after the cause with an earnestness proportioned to our alarm; our perplexity augments in a ratio equivalent to the persuasion we are under: how essentially requisite it is, we should become acquainted with the cause that has affected us in so lively a manner. As it frequently happens that our senses can teach us nothing respecting this cause which so deeply interests us—which we seek with so much ardour, we have recourse to our imagination; this, disturbed with alarm, enervated by fear, becomes a suspicious, a fallacious guide: we create chimeras, fictitious causes, to whom we give the credit, to whom we ascribe the honour of those phenomena by which we have been so much alarmed. It is to this disposition of the human mind that must be attributed, as will be seen in the sequel, the religious errors of man, who, despairing of the capacity to trace the natural causes of those perplexing phenomena to which he was the witness, and sometimes the victim, created in his brain (heated with terror) imaginary causes, which have become to him a source of the most extravagant folly.
In Nature, however, there can be only natural causes and effects; all motion excited in this Nature, follows constant and necessary laws: the natural operations, to the knowledge of which we are competent, of which we are in a capacity to judge, are of themselves sufficient to enable us to discover those which elude our sight; we can at least judge of them by analogy. If we study Nature with attention, the modes of action which she displays to our senses will teach us not to be disconcerted by those which she refuses to discover. Those causes which are the most remote from their effects, unquestionably act by intermediate causes; by the aid of these, we can frequently trace out the first. If in the chain of these causes we sometimes meet with obstacles that oppose themselves to our research, we ought to endeavour by patience and diligence to overcome them; when it so happens we cannot surmount the difficulties that occur, we still are never justified in concluding the chain to be broken, or that the cause which acts is SUPER-NATURAL. Let us, then, be content with an honest avowal, that Nature contains resources of which we are ignorant; but never let us substitute phantoms, fictions, or imaginary causes, senseless terms, for those causes which escape our research; because, by such means we only confirm ourselves in ignorance, impede our enquiries, and obstinately remain in error.
In spite of our ignorance with respect to the meanderings of Nature, (for of the essence of being, of their properties, their elements, their combinations, their proportions, we yet know the simple and general laws, according to which bodies move;) we see clearly, that some of these laws, common to all beings, never contradict themselves; although, on some occasions, they appear to vary, we are frequently competent to discover that the cause becoming complex, from combination with other causes, either impedes or prevents its mode of action being such as in its primitive state we had a right to expect. We know that active, igneous matter, applied to gunpowder, must necessarily cause it to explode: whenever this effect does not follow the combination of the igneous matter with the gunpowder—whenever our senses do not give us evidence of the fact, we are justified in concluding, either that the powder is damp, or that it is united with some other substance that counteracts its explosion. We know that all the actions of man have a tendency to render him happy: whenever, therefore, we see him labouring to injure or destroy himself, it is just to infer that he is moved by some cause opposed to his natural tendency; that he is deceived by some prejudice; that, for want of experience, he is blind to consequences: that he does not see whither his actions will lead him.
If the motion excited in beings was always simple; if their actions did not blend and combine with each other, it would be easy to know, and we should be assured, in the first instance, of the effect a cause would produce. I know that a stone, when descending, ought to describe a perpendicular: I also know, that if it encounters any other body which changes its course, it is obliged to take an oblique direction, but if its fall be interrupted by several contrary powers, which act upon it alternately, I am no longer competent to determine what line it will describe. It may be a parabola, an ellipsis, spiral, circular, &c. this will depend on the impulse, it receives, and the powers by which it is impelled.
The most complex motion, however, is never more than the result of simple motion combined: therefore as soon as we know the general laws of beings and their action, we have only to decompose, to analyse them, in order to discover those of which they are combined; experience teaches us the effects we are to expect. Thus it is clear, the simplest motion causes that necessary junction of different matter, of which all bodies are composed: that matter, varied in its essence, in its properties, in its combinations, has each its several modes of action or motion, peculiar to itself; the whole motion of a body is consequently the sum total of each particular motion that is combined.
Amongst the matter we behold, some is constantly disposed to unite, whilst other is incapable of union; that which is suitable to unite, forms combinations, more or less intimate, possessing more or less durability: that is to say, with more or less capacity to preserve their union, to resist dissolution. Those bodies which are called SOLIDS, receive into their composition a great number of homogeneous, similar, and analogous particles, disposed to unite themselves with energies conspiring or tending to the same point. The primitive beings, or elements of bodies, have need of supports, of props; that is to say, of the presence of each other, for the purpose of preserving themselves; of acquiring consistence or solidity: a truth, which applies with equal uniformity to what is called physical, as to what is termed moral.
It is upon this disposition in matter and bodies, with relation to each other, that is founded those modes of action which natural philosophers designate by the terms attraction, repulsion, sympathy, antipathy, affinities, relations; that moralists describe under the names of love, hatred, friendship, aversion. Man, like all the beings in nature, experiences the impulse of attraction and repulsion; the motion excited in him differing from that of other beings, only, because it is more concealed, and frequently so hidden, that neither the causes which excite it, nor their mode of action are known. This system of attraction and repulsion is very ancient, although it required a NEWTON to develop it. That love, to which the ancients attributed the unfolding, or disentanglement of chaos, appears to have been nothing more than a personification of the principle of attraction. All their allegories and fables upon chaos, evidently indicate nothing more than the accord or union that exists between analogous and homogeneous substances; from whence resulted the existence of the universe: whilst discord or repulsion, which they called SOIS, was the cause of dissolution, confusion, and disorder; there can scarcely remain a doubt, but this was the origin of the doctrines of the TWO PRINCIPLES. According to DIOGENES LAERTIUS, the philosopher, EMPEDOCLES, asserted, that "there is a kind of affection by which the elements unite themselves; and a sort of discord, by which they separate or remove themselves."
However it may be, it is sufficient for us to know that by an invariable law, certain bodies are disposed to unite with more or less facility; whilst others cannot combine or unite themselves: water combines itself readily with salt, but will not blend with oil. Some combinations are very strong, cohering with great force, as metals; others are extremely feeble, their cohesion slight and easily decomposed, as in fugitive colours. Some bodies, incapable of uniting by themselves, become susceptible of union by the agency of other bodies, which serve for common bonds or MEDIUMS. Thus, oil and water, naturally heterogeneous, combine and make soap, by the intervention of alkaline salt. From matter diversely combined, in proportions varied almost to infinity, result all physical and moral bodies; the properties and qualities of which are essentially different, with modes of action more or less complex: which are either understood with facility, or difficult of comprehension, according to the elements or matter that has entered into their composition, and the various modifications this matter has undergone.
It is thus, from the reciprocity of their attraction, the primitive imperceptible particles of matter, which constitute bodies, become perceptible, form compound substances, aggregate masses; by the union of similar and analogous matter, whose essences fit them to cohere. The same bodies are dissolved, their union broken, whenever they undergo the action of matter inimical to their junction. Thus by degrees are formed, plants, metals, animals, men; each grows, expands, and increases in its own system or order; sustaining itself in its respective existence, by the continual attraction of analogous matter; to which it becomes united, and by which it is preserved and strengthened. Thus, certain aliments become fit for the sustenance of man, whilst others destroy his existence: some are pleasant to him, strengthen his habit; others are repugnant to him, weaken his system: in short, never to separate physical from moral laws, it is thus that men, mutually attracted to each other by their reciprocal wants, form those unions which we designate by the terms, MARRIAGE, FAMILIES, SOCIETIES, FRIENDSHIPS, CONNEXIONS: it is thus that virtue strengthens and consolidates them; that vice relaxes or totally dissolves them.
Of whatever nature may be the combination of beings, their motion has always one direction or tendency: without direction we could not have any idea of motion: this direction is regulated by the properties of each being; as soon as they have any given properties, they necessarily act in obedience to them: that is to say, they follow the law invariably determined by these same properties; which, of themselves, constitute the being such as he is found, and settle his mode of action, which is always the consequence of his manner of existence. But what is the general direction, or common tendency, we see in all beings? What is the visible and known end of all their motion? It is to conserve their actual existence—to preserve themselves—to strengthen their several bodies—to attract that which is favorable to them—to repel that which is injurious them—to avoid that which can harm them—to resist impulsions contrary to their manner of existence, and to their natural tendency.
To exist, is to experience the motion peculiar to a determinate essence: to conserve this existence, is to give and receive that motion from which results its maintenance:—it is to attract matter suitable to corroborate its being—to avoid that by which it may be either endangered or enfeebled. Thus, all beings of which we have any knowledge, have a tendency to conserve themselves, each after its peculiar manner: the stone, by the firm adhesion of its particles, opposes resistance to its destruction. Organized beings conserve themselves by more complicated means, but which are, nevertheless, calculated to maintain their existence against that by which it may be injured. Man, both in his physical and in his moral capacity, is a living, feeling, thinking, active being; who, every instant of his duration, strives equally to avoid that which may be injurious, and to procure that which is pleasing to him, or that which is suitable to his mode of existence; all his actions tending solely to conserve himself. ST. AUGUSTINE admits this tendency in all whether organized or not.
Conservation, then, is the common point to which all the energies, all the powers, all the faculties of beings, seem continually directed. Natural philosophers call this direction or tendency, SELF-GRAVITATION: NEWTON calls it INERT FORCE: moralists denominate it in man, SELF-LOVE which is nothing more than the tendency he has to preserve himself—a desire of happiness—a love of his own welfare—a wish for pleasure—a promptitude in seizing on every thing that appears favourable to his conservation—a marked aversion to all that either disturbs his happiness, or menaces his existence—primitive sentiments, that are common to all beings of the human species; which all their faculties are continually striving to satisfy; which all their passions, their wills, their actions, have eternally for their object and their end. This self-gravitation, then, is clearly a necessary disposition in man, and in all other beings; which, by a variety means, contribute to the preservation of the existence they have received, as long as nothing deranges the order of their machine, or its primitive tendency.
Cause always produces effect; there can be no effect without cause. Impulse is always followed by some motion, more or less sensible; by some change, more or less remarkable in the body which receives it. But motion, and its various modes of displaying itself, is, as has been already shewn, determined by the nature, the essence, the properties, the combinations of the beings acting. It must, then, be concluded that motion, or the modes by which beings act, arises from some cause; that as this cause is not able to move or act, but in conformity with the manner of its being or its essential properties, it must equally be concluded, that all the phenomena we perceive are necessary; that every being in Nature, under the circumstances in which it is placed, and with the given properties it possesses, cannot act otherwise than it does.
Necessity is the constant and infallible relation of causes with their effects. Fire consumes, of necessity, combustible matter plated within its circuit of action: man, by fatality, desires either that which really is, or appears to be serviceable to his welfare. Nature, in all the extraordinary appearances she exhibits, necessarily acts after her own peculiar essence: all the beings she contains, necessarily act each after its own a individual nature: it is by motion that the whole has relation with its parts; and these parts with the whole: it is thus that in the general system every thing is connected: it is itself but an immense chain of causes and effects, which flow without ceasing, one from the other. If we reflect, we shall be obliged to acknowledge that every thing we see is necessary; that it cannot be otherwise than it is; that all the beings we behold, as well as those which escape our sight, act by invariable laws. According to these laws, heavy bodies fall—light bodies ascend—analogous substances attract each other—beings tend to preserve themselves—man cherishes himself; loves that which he thinks advantageous—detests that which he has an idea may prove unfavourable to him.—In fine, we are obliged to admit, there can be no perfectly independent energy—no separated cause—no detached action, in a nature where all the beings are in a reciprocity of action—who, without interruption, mutually impel and resist each other—who is herself nothing more than an eternal circle of motion, given and received according to necessary laws; which under the same given incidents, invariably produce the same effect.
Two examples will serve to throw the principle here laid down, into light—one shall be taken from physics, the other from morals.
In a whirlwind of dust, raised by elemental force, confused as it appears to our eyes, in the most frightful tempest excited by contrary winds, when the waves roll high as mountains, there is not a single particle of dust, or drop of water, that has been placed by CHANCE, that has not a cause for occupying the place where it is found; that does not, in the most rigorous sense of the word, act after the manner in which it ought to act; that is, according to its own peculiar essence, and that of the beings from whom it receives this communicated force. A geometrician exactly knew the different energies acting in each case, with the properties of the particles moved, could demonstrate that after the causes given, each particle acted precisely as it ought to act, and that it could not have acted otherwise than it did.
In those terrible convulsions that sometimes agitate political societies, shake their foundations, and frequently produce the overthrow of an empire; there is not a single action, a single word, a single thought, a single will, a single passion in the agents, whether they act as destroyers, or as victims, that is not the necessary result of the causes operating; that does not act, as, of necessity, it must act, from the peculiar essence of the beings who give the impulse, and that of the agents who receive it, according to the situation these agents fill in the moral whirlwind. This could be evidently proved by an understanding capacitated to rate all the action and re-action, of the minds and bodies of those who contributed to the revolution.
In fact, if all be connected in Nature, if all motion be produced, the one from the other, notwithstanding their secret communications frequently elude our sight; we ought to feel convinced of this truth, that there is no cause, however minute, however remote, that does not sometimes produce the greatest and most immediate effects on man. It may, perhaps, be in the parched plains of Lybia, that are amassed the first elements of a storm or tempest, which, borne by the winds, approach our climate, render our atmosphere dense, and thus operating on the temperament, may influence the passions of a man, whose circumstances shall have capacitated him to influence many others, who shall decide after his will the fate of many nations.
Man, in fact, finds himself in Nature, and makes a part of it: he acts according to laws, which are appropriate to him; he receives in a manner more or less distinct, the action and impulse of the beings who surround him; who themselves act after laws that are peculiar to their essence. Thus he is variously modified; but his actions are always the result of his own energy, and that of the beings who act upon him, and by whom he is modified. This is what gives such variety to his determinations—what generally produces such contradiction in his thoughts, his opinions, his will, his actions; in short, in that motion, whether concealed or visible, by which he is agitated. We shall have occasion, in the sequel, to place this truth, at present so much contested, in a clearer light: it will be sufficient for our purpose at present to prove, generally, that every thing in Nature is necessary—that nothing to be found in it can act otherwise than it does.
Motion, alternately communicated and received, establishes the connection or relation between the different orders of beings: when they are in the sphere of reciprocal action, attraction approximates them; repulsion dissolves and separates them; the one strengthens and preserves them; the other enfeebles and destroys them. Once combined, they have a tendency to conserve themselves in that mode of existence, by virtue of their inert force; in this they cannot succeed, because they are exposed to the continual influence of all other beings, who perpetually and successively act upon them; their change of form, their dissolution, is requisite to the preservation of Nature herself: this is the sole end we are able to assign her—to which we see her tend without intermission—which she follows without interruption, by the destruction and reproduction of all subordinate beings, who are obliged to submit to her laws—to concur, by their mode of action, to the maintenance of her active existence, so essentially requisite to the GREAT WHOLE.
It is thus each being is an individual, who, in the great family, performs his necessary portion of the general labour—who executes the unavoidable task assigned to him. All bodies act according to laws, inherent in their peculiar essence, without the capability to swerve, even for a single instant, from those according to which Nature herself acts. This is the central power, to which all other powers, essences, and energies, are submitted: she regulates the motions of beings, by the necessity of her own peculiar essence: she makes them concur by various modes to the general plan: this appears to be nothing more than the life, action, and maintenance of the whole, by the continual change of its parts. This object she obtains, in removing them, one by the other; by that which establishes, and by that which destroys, the relation subsisting between them; by that which gives them, and that which deprives them of, their forms, combinations, proportions, and qualities, according to which they act for a time, after a given mode; these are afterwards taken from them, to make them act after a different manner. It is thus that Nature makes them expand and change, grow and decline, augment and diminish, approximate and remove, forms and destroys them, according as she finds it requisite to maintain the whole; towards the conservation which this Nature is herself essentially necessitated to have a tendency.
This irresistible power, this universal necessity, this general energy, then, is only a consequence of the nature of things; by virtue of which every thing acts, without intermission, after constant and immutable laws: these laws not varying more for the whole than for the beings of which it is composed. Nature is an active living whole, to which all its parts necessarily concur; of which, without their own knowledge, they maintain the activity, the life, and the existence. Nature acts and exists necessarily: all that she contains, necessarily conspires to perpetuate her active existence. This is the decided opinion of PLATO, when he says, "matter and necessity are the same thing; this necessity is the mother of the world." In point of fact, we cannot go beyond this aphorism, MATTER ACTS, BECAUSE IT EXISTS; AND EXISTS, TO ACT. If it be enquired how, or for why, matter exists? We answer, we know not: but reasoning by analogy, of what we do not know by that which we do, we should be of opinion it exists necessarily, or because it contains within itself a sufficient reason for its existence. In supposing it to be created or produced by a being distinguished from it, or less known than itself, (which it may be, for any thing we know to the contrary,) we must still admit, that this being is necessary, and includes a sufficient reason for his own existence. We have not then removed any of the difficulty, we have not thrown a clearer light upon the subject, we have not advanced a single step; we have simply laid aside a being, of which we know some few of the properties, but of which we are still extremely ignorant, to have recourse to a power, of which it is utterly impossible we can, as long as we are men, form any distinct idea; of which, notwithstanding it may be a truth, we cannot, by any means we possess, demonstrate the existence. As, therefore, these must be at best but speculative points of belief, which each individual, by reason of its obscurity, may contemplate with different optics, under various aspects, they surely ought to be left free for each to judge after his own fashion: the Hindoo can have no just cause of enmity against the Christian for his faith: this has no moral right to question the Mussulman upon his; the numerous sects of each of the various persuasions spread over the face of the earth, ought to make it a creed to look with an eye of complacency on the deviation of the others; and rest upon that great moral axiom, which is strictly conformable to Nature, which contains the whole of man's happiness—"Do not unto another, that which do you not wish another should do unto you;" for it is evident, according to their own doctrines, out of all the variety of systems, one only can be right.
We shall see in the sequel, how much man's imagination labours to form an idea, of the energies of that Nature he has personified, and distinguished from herself: in short, we shall examine some of the ridiculous and pernicious inventions, which, for want of understanding Nature, have been imagined to impede her course, to suspend her eternal laws, to place obstacles to the necessity of things.
CHAP. V.
Order and Confusion.—Intelligence.—Chance.
The observation of the necessary, regular, and periodical motion in the universe, generated in the mind of man the idea of ORDER; this term, in its original signification, represents nothing more than a mode of considering, a facility of perceiving, together and separately, the different relations of a whole; in which is discovered, by its manner of existing and acting, a certain affinity or conformity with his own. Man, in extending this idea to the universe, carried with him those methods of considering things which are peculiar to himself: he has consequently supposed there really existed in Nature affinities and relations, which he classed under the name of ORDER; and others which appeared to him not to conform to those, which he has ranked under the term of CONFUSION.
It is easy to comprehend, that this idea of order and confusion can have no absolute existence in Nature, where every thing is necessary; where the whole follows constant and invariable laws, which oblige each being, in every moment of its duration, to submit to other laws, which flow from its own peculiar mode of existence. Therefore it is in his imagination, only, man finds a model of that which he terms order or confusion; which, like all his abstract, metaphysical ideas, supposes nothing beyond his reach. Order, however, is never more than the faculty of conforming himself with the beings by whom he is environed, or with the whole of which he forms a part.
Nevertheless, if the idea of order be applied to Nature, it will be found to be nothing but a series of action or motion, which he judges to conspire to one common end. Thus, in a body that moves, order is the chain of action, the series of motion, proper to constitute it what it is, and to maintain it in its actual state. Order, relatively to the whole of Nature, is the concatenation of causes and effects, necessary to her active existence—to maintaining her constantly together; but, as it has been proved in the chapter preceding, every individual being is obliged to concur to this end, in the different ranks they occupy; from whence it is a necessary deduction, that what is called the ORDER OF NATURE, can never be more than a certain manner of considering the necessity of things, to which all, of which man has any knowledge, is submitted. That which is styled CONFUSION, is only a relative term, used to designate that series of necessary action, that chain of requisite motion, by which an individual being is necessarily changed or disturbed in its mode of existence—by which it is instantaneously obliged to alter its manner of action; but no one of these actions, no part of this motion is capable, even for a single instant, of contradicting or deranging the general order of Nature; from which all beings derive their existence, their properties, the motion appropriate to each.
What is termed confusion in a being, is nothing more than its passage into a new class, a new mode of existence; which necessarily carries with it a new series of action, a new chain of motion, different from that of which this being found itself susceptible in the preceding rank it occupied. That which is called order, in Nature, is a mode of existence, or a disposition of its particles, strictly necessary. In every other assemblage of causes and effects, of worlds, as well as in that which we inhabit, some sort of arrangement, some kind of order would necessarily be established. Suppose the most incongruous, the most heterogeneous substances were put into activity, and assembled by a concatenation of extraordinary circumstances; they would form amongst themselves, a complete order, a perfect arrangement. This is the true notion of a property, which may be defined, an aptitude to constitute a being, such as it is actually found, such as it is with respect to the whole of which it makes a part.
Order, then, is nothing but necessity, considered relatively to the series of actions, or the connected chain of causes and effects, that it produces in the universe. What is the motion in our planetary system; but a series of phenomena, operated upon according to necessary laws, that regulate the bodies of which it is composed? In conformity to these laws, the sun occupies the centre; the planets gravitate towards it, and revolve round it, in regulated periods: the satellites of these planets gravitate towards those which are in the centre of their sphere of action, and describe round them their periodical route. One of these planets, the earth which man inhabits, turns on its own axis; and by the various aspects which its revolution obliges it to present to the sun, experiences those regular variations which are called SEASONS. By a sequence of the sun's action upon different parts of this globe, all its productions undergo vicissitudes: plants, animals, men, are in a sort of morbid drowsiness during Winter: in Spring, these beings re-animate, to come as it were out of a long lethargy. In short, the mode in which the earth receives the sun's beams, has an influence on all its productions; these rays, when darted obliquely, do not act in the same manner as when they fall perpendicularly; their periodical absence, caused by the revolution of this sphere on itself, produces night and day. However, in all this, man never witnesses more than necessary effects, flowing from the nature of things, which, whilst that remains the same, can never be opposed with propriety. These effects are owing to gravitation, attraction, centrifugal power, &c.
On the other hand, this order, which man admires as a supernatural effect, is sometimes disturbed, or changed into what he calls confusion: this confusion is, however, always a necessary consequence of the laws of Nature; in which it is requisite to the support of the whole that some of her parts should be deranged and thrown out of the ordinary course. It is thus, COMETS present themselves so unexpectedly to man's wondering eyes; their eccentric motion disturbs the tranquillity of his planetary system; they excite the terror of the misinstructed to whom every thing unusual is marvellous. The natural philosopher, himself, conjectures that in former ages, these comets have overthrown the surface of this mundane ball, and caused great revolutions on the earth. Independent of this extraordinary confusion, he is exposed to others more familiar to him: sometimes, the seasons appear to have usurped each other's place; to have quitted their regular order: sometimes the opposing elements seem to dispute among themselves the dominion of the world; the sea bursts its limits; the solid earth is shaken and rent asunder; mountains are in a state of conflagration; pestilential diseases destroy both men and animals; sterility desolates a country: then affrighted man utters piercing cries, offers up his prayers to recall order; tremblingly raises his hands towards the Being he supposes to be the author of all these calamities; nevertheless, the whole of this afflicting confusion are necessary effects, produced by natural causes; which act according to fixed laws, determined by their own peculiar essence, and the universal essence of Nature: in which every thing must necessarily be changed, moved, and dissolved; where that which is called ORDER, must sometimes be disturbed and altered into a new mode of existence; which to his deluded mind, to his imagination, led astray by ignorance and want of reflection, appears CONFUSION.
There cannot possibly exist what is generally termed a confusion of Nature: man finds order in every thing that is conformable to his own mode of being; confusion in every thing by which it is opposed: nevertheless, in Nature, all is in order; because none of her parts are ever able to emancipate themselves from those invariable rules which flow from their respective essences: there is not, there cannot be confusion in a whole, to the maintenance of which what is called confusion is absolutely requisite; of which the general course can never be discomposed, although individuals may be, and necessarily are; where all the effects produced are the consequence of natural causes, that under the circumstances in which they are placed, act only as they infallibly are obliged to act.
It therefore follows, there can be neither monsters nor prodigies; wonders nor miracles in Nature: those which are designated MONSTERS, are certain combinations, with which the eyes of man are not familiarized; but which, therefore, are not less the necessary effects of natural causes. Those which he terms PRODIGIES, WONDERS, or SUPERNATURAL effects, are phenomena of Nature, with whose mode of action he is unacquainted; of which his ignorance does not permit him to ascertain the principles; whose causes he cannot trace; but which his impatience, his heated imagination, aided by a desire to explain, makes him foolishly attribute to imaginary causes; which, like the idea of order, have no existence but in himself; and which, that he may conceal his own ignorance, that he may obtain more respect with the uninformed, he places beyond Nature, out of which his experience is every instant demonstrably proving that none of these things can have existence.
As for those effects which are called MIRACLES, that is to say, contrary to the unalterable laws of Nature, it must be felt such things are impossible; because, nothing can, for an instant, suspend the necessary course of beings, without the whole of Nature was arrested; without she was disturbed in her tendency. There have neither been wonders nor miracles in Nature; except for those, who have not sufficiently studied the laws, who consequently do not feel, that those laws can never be contradicted, even in the most minute parts, without the whole being destroyed, or at least without changing her essence, her mode of action; that it is the height of folly to recur to supernatural causes to explain the phenomena man beholds, before he becomes fully acquainted with natural causes—with the powers and capabilities which Nature herself contains.
Order and Confusion, then, are only relative terms, by which man designates the state in which particular beings find themselves. He says, a being is in order, when all the motion it undergoes conspires to favor its tendency to its own preservation; when it is conducive to the maintenance of its actual existence: that it is in confusion when the causes which move it disturb the harmony of its existence, or have a tendency to destroy the equilibrium necessary to the conservation of its actual state. Nevertheless, confusion, as we have shown, is nothing but the passage of a being into a new order; the more rapid the progress, the greater the confusion for the being that is submitted to it: that which conducts man to what is called death, is, for him, the greatest of all possible confusion. Yet this death is nothing more than a passage into a new mode of existence: it is the eternal, the invariable, the unconquerable law of Nature, to which the individuals of his order, each in his turn, is obliged to submit.
The human body is said to be in order, when its various component parts act in that mode, from which results the conservation of the whole; from which emanates that which is the tendency of his actual existence; in other words, when all the impulse he receives, all the motion he communicates, tends to preserve his health, to render him happy, by promoting the happiness of his fellow men. He is said to be in health when the fluids and solids of his body concur to render him robust, to keep his mind in vigour; when each lends mutual aid towards this end. He is said to be in confusion, or in ill health, whenever this tendency is disturbed; when any of the essential parts of his body cease to concur to his preservation, or to fulfil its peculiar functions. This it is that happens in a state of sickness, in which, however, the motion excited in the human machine is as necessary, is regulated by laws as certain, as natural, as invariable, as that which concurs to produce health. Sickness merely produces in him a new order of motion, a new series of action, a new chain of things. Man dies: to him, this appears the greatest confusion he can experience; his body is no longer what it was—its parts no longer concur to the same end—his blood has lost its circulation—he is deprived of feeling—his ideas have vanished—he thinks no more—his desires have fled—death is the epoch, the cessation of his human existence.—His frame becomes an inanimate mass, by the subtraction of those principles by which it was animated; that is, which made it act after a determinate manner: its tendency has received a new direction; its action is changed; the motion excited in its ruins conspires to a new end. To that motion, the harmony of which he calls order, which produced life, sentiment, thought, passions, health, succeeds a series of motion of another species; that, nevertheless, follows laws as necessary as the first; all the parts of the dead man conspire to produce what is called dissolution, fermentation, putrefaction: these new modes of being, of acting, are just as natural to man, reduced to this state, as sensibility, thought, the periodical motion of the blood, &c. were to the living man: his essence having changed, his mode of action can no longer be the same. To that regulated motion, to that necessary action, which conspired to the production of life, succeeds that determinate motion, that series of action which concurs to produce the dissolution of the dead carcass; the dispersion of its parts; the formation of new combinations, from which result new beings; and which, as we have before seen, is the immutable order of active Nature.
How then can it be too often repeated, that relatively to the great whole, all the motion of beings, all their modes of action, can never be but in order, that is to say, are always conformable to Nature; that in all the stages through which beings are obliged to pass, they invariably act after a mode necessarily subordinate to the universal whole? To say more, each individual being always acts in order; all its actions, the whole system of its motion, are the necessary consequence of its peculiar mode of existence; whether that be momentary or durable. Order, in political society, is the effect of a necessary series of ideas, of wills, of actions, in those who compose it; whose movements are regulated in a manner, either calculated to maintain its indivisibility, or to hasten its dissolution. Man constituted, or modified, in the manner we term virtuous, acts necessarily in that mode, from whence results the welfare of his associates: the man we stile wicked, acts necessarily in that mode, from whence springs the misery of his fellows: his Nature, being essentially different, he must necessarily act after a different mode: his individual order is at variance, but his relative order is complete: it is equally the essence of the one, to promote happiness, as it is of the other to induce misery.
Thus, order and confusion in individual beings, is nothing more than the manner of man's considering the natural and necessary effects, which they produce relatively to himself. He fears the wicked man; he says that he will carry confusion into society, because he disturbs its tendency and places obstacles to its happiness. He avoids a falling stone, because it will derange in him the order necessary to his conservation. Nevertheless, order and confusion, are always, as we have shewn, consequences, equally necessary to either the transient or durable state of beings. It is in order that fire burns, because it is of its essence to burn; on the other hand, it is in order, that an intelligent being should remove himself from whatever can disturb his mode of existence. A being, whose organization renders him sensible, must in virtue of his essence, fly from every thing that can injure his organs, or that can place his existence in danger.
Man calls those beings intelligent, who are organized after his own manner; in whom he sees faculties proper for their preservation; suitable to maintain their existence in the order that is convenient to them; that can enable them to take the necessary measures towards this end, with a consciousness of the motion they undergo. From hence, it will be perceived, that the faculty called intelligence, consists in a possessing capacity to act comformably to a known end, in the being to which it is attributed. He looks upon these beings as deprived of intelligence, in which he finds no conformity with himself; in whom he discovers neither the same construction, nor the same faculties: of which he knows neither the essence, the end to which they tend, the energies by which they act, nor the order that is necessary to them. The whole cannot have a distinct name, or end, because there is nothing out of itself, to which it can have a tendency. If it be in himself, that he arranges the idea of order, it is also in himself, that he draws up that of intelligence. He refuses to ascribe it to those beings, who do not act after his own manner: he accords it to all those whom he supposes to act like himself: the latter he calls intelligent agents: the former blind causes; that is to say, intelligent agents who act by chance: thus chance is an empty word without sense, but which is always opposed to that of intelligence, without attaching any determinate, or any certain idea.
Man, in fact, attributes to chance all those effects, of which the connection they have with their causes is not seen. Thus he uses the word chance, to cover his ignorance of those natural causes, which produce visible effects, by means which he cannot form an idea of; or that act by a mode of which he does not perceive the order; or whose system is not followed by actions conformable to his own. As soon as he sees, or believes he sees, the order of action, or the manner of motion, he attributes this order to an intelligence; which is nothing more than a quality borrowed from himself—from his own peculiar mode of action—from the manner in which he is himself affected.
Thus an intelligent being is one who thinks, who wills, and who acts, to compass an end. If so, he must have organs, an aim conformable to those of man: therefore, to say Nature is governed by an intelligence, is to affirm that she is governed by a being, furnished with organs; seeing that without this organic construction, he can neither have sensations, perceptions, ideas, thought, will, plan, nor action which he understands.
Man always makes himself the center of the universe: it is to himself that he relates all he beholds. As soon as he believes he discovers a mode of action that has a conformity with his own, or some phenomenon that interests his feelings, he attributes it to a cause that resembles himself—that acts after his manner—that has faculties similar to those he possesses—whose interests are like his own—whose projects are in unison with and have the same tendency as those he himself indulges: in short, it is from himself, or the properties which actuate him, that he forms the model of this cause. It is thus that man beholds, out of his own species, nothing but beings who act differently from himself; yet believes that he remarks in Nature an order similar to his own ideas—views conformable to those which he himself possesses. He imagines that Nature is governed by a cause whose intelligence is conformable to his own, to whom he ascribes the honor of the order which he believes he witnesses—of those views that fall in with those that are peculiar to himself—of an aim which quadrates with that which is the great end of all his own actions. It is true that man, feeling his incapability of producing the vast, the multiplied effects of which he witnesses the operation, when contemplating the universe, was under the necessity of making a distinction between himself and the cause which he supposed to be the author of such stupendous effects; he believed he removed every difficulty, by amplifying in this cause all those faculties of which he was himself in possession; adding others of which his own self-love made him desirous, or which he thought would render his being more perfect: thus, he gave JUPITER wings, with the faculty of assuming any form he might deem convenient: it was thus, by degrees, he arrived at forming an idea of that intelligent cause, which he has placed above Nature, to preside over action—to give her that motion of which he has chosen to believe she was in herself incapable. He obstinately persists in regarding this Nature as a heap of dead, inert matter, without form, which has not within itself the power of producing any of those great effects, those regular phenomena, from which emanates what he styles the order of the Universe. ANAXAGORAS is said to have been the first who supposed the universe created and governed by an intelligence: ARISTOTLE reproaches him with having made an automaton of this intelligence; or in other words, with ascribing to it the production of things, only when he was at a loss to account for their appearance. From whence it may be deduced, that it is for want of being acquainted with the powers of Nature, or the properties of matter, that man has multiplied beings without necessity—that he has supposed the universe under the government of an intelligent cause, which he is, and perhaps always will be, himself the model: in fine, this cause has been personified under such a variety of shapes, sexes, and names, that a list of the deities he has at various times supposed to guide this Nature, or to whom he has submitted her, makes a large volume that occupies some years of his youthful education to understand. He only rendered this cause more inconceivable, when he extended in it his own faculties too much. He either annihilates, or renders it altogether impossible, when he would attach to it incompatible qualities, which he is obliged to do, to enable him to account for the contradictory and disorderly effects he beholds in the world. In fact, he sees confusion in the world; yet, notwithstanding his confusion contradicts the plan, the power, the wisdom, the bounty of this intelligence, and the miraculous order which he ascribes to it; he says, the extreme beautiful arrangement of the whole, obliges him to suppose it to be the work of a sovereign intelligence: unable, however, to reconcile this seeming confusion with the benevolence he attaches to this cause, he had recourse to another effort of his imagination; he made a new cause, to whom he ascribed all the evil, all the misery, resulting from this confusion: still, his own person served for the model; to which he added those deformities which he had learned to hold in disrespect: in multiplying these counter or destroying causes, he peopled Pandemonium.
It will no doubt be argued, that as Nature contains and produces intelligent beings, either she must be herself intelligent, or else she must be governed by an intelligent cause. We reply, intelligence is a faculty peculiar to organized beings, that it is to say, to beings constituted and combined after a determinate manner; from whence results certain modes of action, which are designated under various names; according to the different effects which these beings produce: wine has not the properties called wit and courage; nevertheless, it is sometimes seen that it communicates those qualities to men, who are supposed to be in themselves entirely devoid of them. It cannot be said Nature is intelligent after the manner of any of the beings she contains; but she can produce intelligent beings by assembling matter suitable to their particular organization, from whose peculiar modes of action will result the faculty called intelligence; who shall be capable of producing certain effects which are the necessary consequence of this property. I therefore repeat, that to have intelligence, designs and views, it is requisite to have ideas; to the production of ideas, organs or senses are necessary: this is what is neither said of Nature nor of the causes he has supposed to preside over her actions. In short experience warrants the assertion, it does more, it proves beyond a doubt, that matter, which is regarded as inert and dead, assumes sensible action, intelligence, and life, when it is combined and organized after particular modes.
From what has been said, it must rationally be concluded that order is never more than the necessary or uniform connection of causes with their effects; or that series of action which flows from the peculiar properties of beings, so long as they remain in a given state; that confusion is nothing more than the change of this state; that in the universe, all is necessarily in order, because every thing acts and moves according to the various properties of the different beings it contains; that in Nature there cannot be either confusion or real evil, since every thing follows the laws of its natural existence; that there is neither chance nor any thing fortuitous in this Nature, where no effect is produced without a sufficient, without a substantial cause; where all causes act necessarily according to fixed and certain laws, which are themselves dependant on the essential properties of these causes or beings, as well as on the combination, which constitutes either their transitory or permanent state; that intelligence is a mode of acting, a method of existence natural to some particular beings; that if this intelligence should be attributed to Nature, it would then be nothing more than the faculty of conserving herself in active existence by necessary means. In refusing to Nature the intelligence he himself enjoys—in rejecting the intelligent cause which is supposed to be the contriver of this Nature, or the principle of that order he discovers in her course, nothing is given to chance, nothing to a blind cause, nothing to a power which is indistinguishable; but every thing he beholds is attributed to real, to known causes; or to those which by analogy are easy of comprehension. All that exists is acknowledged to be a consequence of the inherent properties of eternal matter, which by contact, by blending, by combination, by change of form, produces order and confusion; with all those varieties which assail his sight, it is himself who is blind, when he imagines blind causes:—man only manifested his ignorance of the powers of motion, of the laws of Nature, when he attributed, any of its effects to chance. He did not shew a more enlightened feeling when he ascribed them to an intelligence, the idea of which he borrowed from himself, but which is never in conformity with the effects which he attributes to its intervention—he only imagined words to supply the place of things—he made JUPITER, SATURN, JUNO, and a thousand others, operate that which he found himself inadequate to perform; he distinguished them from Nature, gave them an amplification of his own properties, and believed he understood them by thus obscuring ideas, which he never dared either define or analyze.
CHAP. VI.
Moral and Physical Distinctions of Man.—His Origin.
Let us now apply the general laws we have scrutinized, to those beings of Nature who interest us the most. Let us see in what man differs from the other beings by which he is surrounded. Let us examine if he has not certain points in conformity with them, that oblige him, notwithstanding the different properties they respectively possess, to act in certain respects according to the universal laws to which every thing is submitted. Finally, let us enquire if the ideas he has formed of himself in meditating on his own peculiar mode of existence, be chimerical, or founded in reason.
Man occupies a place amidst that crowd, that multitude of beings, of which Nature is the assemblage. His essence, that is to say, the peculiar manner of existence, by which he is distinguished from other beings, renders him susceptible of various modes of action, of a variety of motion, some of which are simple and visible, others concealed and complicated. His life itself is nothing more than a long series, a succession of necessary and connected motion; which operates perpetual changes in his machine; which has for its principle either causes contained within himself, such as blood, nerves, fibres, flesh, bones; in short, the matter, as well solid as fluid, of which his body is composed—or those exterior causes, which, by acting upon him, modify him diversely; such as the air with which he is encompassed, the aliments by which he is nourished, and all those objects from which he receives any impulse whatever, by the impression they make on his senses.
Man, like all other beings in Nature, tends to his own destruction—he experiences inert force—he gravitates upon himself—he is attracted by objects that are contrary or repugnant to his existence—he seeks after some—he flies, or endeavours to remove himself from others. It is this variety of action, this diversity of modification of which the human being is susceptible, that has been designated under such different names, by such varied nomenclature. It will be necessary, presently, to examine these closely and go more into detail.
However marvellous, however hidden, however secret, however complicated may be the modes of action, which the human frame undergoes, whether interiorly or exteriorly; whatever may be, or appear to be the impulse he either receives or communicates, examined closely, it will be found that all his motion, all his operations, all his changes, all his various states, all his revolutions, are constantly regulated by the same laws, which Nature has prescribed to all the beings she brings forth—which she developes—which she enriches with faculties—of which she increases the bulk—which she conserves for a season—which she ends by decomposing, by destroying: obliging them to change their form.
Man, in his origin, is an imperceptible point, a speck, of which the parts are without form; of which the mobility, the life, escapes his senses; in short, in which he does not perceive any sign of those qualities, called SENTIMENT, FEELING, THOUGHT, INTELLIGENCE, FORCE, REASON, &c. Placed in the womb suitable to his expansion, this point unfolds, extends, increases, by the continual addition of matter he attracts, that is analogous to his being, which consequently assimilates itself with him. Having quitted this womb, so appropriate to conserve his existence, to unfold his qualities, to strengthen his habits; so competent to give, for a season, consistence to the weak rudiments of his frame; he travels through the stage of infancy; he becomes adult: his body has then acquired a considerable extension of bulk, his motion is marked, his action is visible, he is sensible in all his parts; he is a living, an active mass; that is to say, a combination that feels and thinks; that fulfils the functions peculiar to beings of his species. But how has he become sensible? Because he has been by degrees nourished, enlarged, repaired by the continual attraction that takes place within himself, of that kind of matter which is pronounced inert, insensible, inanimate; which is, nevertheless, continually combining itself with his machine; of which it forms an active whole, that is living, that feels, judges, reasons, wills, deliberates, chooses, elects; that has the capability of labouring, more or less efficaciously, to his own individual preservation; that is to say, to the maintenance of the harmony of his existence.
All the motion and changes that man experiences in the course of his life, whether it be from exterior objects or from those substances contained within himself, are either favorable or prejudicial to his existence; either maintain its order, or throw it into confusion; are either in conformity with, or repugnant to, the essential tendency of his peculiar mode of being. He is compelled by Nature to approve of some, to disapprove of others; some of necessity render him happy, others contribute to his misery; some become the objects of his most ardent desire, others of his determined aversion: some elicit his confidence, others make him tremble with fear.
In all the phenomena man presents, from the moment he quits the womb of his mother, to that wherein he becomes the inhabitant of the silent tomb, he perceives nothing but a succession of necessary causes and effects, which are strictly conformable to those laws that are common to all the beings in Nature. All his modes of action—all his sensations—all his ideas—all his passions—every act of his will—every impulse which he either gives or receives, are the necessary consequences of his own peculiar properties, and those which he finds in the various beings by whom he is moved. Every thing he does—every thing that passes within himself—his concealed motion—his visible action, are the effects of inert force—of self-gravitation—the attractive or repulsive powers contained in his machine—of the tendency he has, in common with other beings, to his own individual preservation; in short, of that energy which is the common property of every being he beholds. Nature, in man, does nothing more than shew, in a decided manner, what belongs to the peculiar nature by which he is distinguished from the beings of a different system or order.
The source of those errors into which man has fallen, when he has contemplated himself, has its rise, as will presently be shown, in the opinion he has entertained, that he moved by himself—that he always acts by his own natural energy—that in his actions, in the will that gave him impulse, he was independent of the general laws of Nature; and of those objects which, frequently, without his knowledge, always in spite of him, in obedience to these laws, are continually acting upon him. If he had examined himself attentively, he must have acknowledged, that none of the motion he underwent was spontaneous—he must have discovered, that even his birth depended on causes, wholly out of the reach of his own powers—that, it was without his own consent he entered into the system in which he occupies a place—that, from the moment in which he is born, until that in which he dies, he is continually impelled by causes, which, in spite of himself, influence his frame, modify his existence, dispose of his conduct. Would not the slightest reflection have sufficed to prove to him, that the fluids, the solids, of which his body is composed, as well as that concealed mechanism, which he believes to be independent of exterior causes, are, in fact, perpetually under the influence of these causes; that without them he finds himself in a total incapacity to act? Would he not have seen, that his temperament, his constitution, did in no wise depend on himself—that his passions are the necessary consequence of this temperament—that his will is influenced, his actions determined by these passions; consequently by opinions, which he has not given to himself, of which he is not the master? His blood, more or less heated or abundant; his nerves more or less braced, his fibres more or less relaxed, give him dispositions either transitory or durable—are not these, at every moment decisive of his ideas; of his thoughts: of his desires: of his fears: of his motion, whether visible or concealed? The state in which he finds himself, does it not necessarily depend on the air which surrounds him diversely modified; on the various properties of the aliments which nourish him; on the secret combinations that form themselves in his machine, which either preserve its order, or throw it into confusion? In short, had man fairly studied himself, every thing must have convinced him, that in every moment of his duration, he was nothing more than a passive instrument in the hands of necessity.
Thus it must appear, that where all is connected, where all the causes are linked one to the other, where the whole forms but one immense chain, there cannot be any independent, any isolated energy; any detached power. It follows then, that Nature, always in action, marks out to man each point of the line he is bound to describe; establishes the route, by which he must travel. It is Nature that elaborates, that combines the elements of which he must be composed;—It is Nature that gives him his being, his tendency, his peculiar mode of action. It is Nature that develops him, expands him, strengthens him, increases his bulk—preserves him for a season, during which he is obliged to fulfil the task imposed on him. It is Nature, that in his journey through life, strews on the road those objects, those events; those adventures, that modify him in a variety of ways, that give him impulses which are sometimes agreeable and beneficial, at others prejudicial and disagreeable. It is Nature, that in giving him feeling, in supplying him with sentiment, has endowed him with capacity to choose, the means to elect those objects, to take those methods that are most conducive, most suitable, most natural, to his conservation. It is Nature, who when he has run his race, when he has finished his career, when he has described the circle marked out for him, conducts him in his turn to his destruction; dissolves the union of his elementary particles, and obliges him to undergo the constant, the universal law; from the operation of which nothing is exempted. It is thus, motion places man in the matrix of his mother; brings him forth out of her womb; sustains him for a season; at length destroys him; obliges him to return into the bosom of Nature; who speedily reproduces him, scattered under an infinity of forms; in which each of his particles run over again, in the same manner, the different stages, as necessary as the whole had before run over those of his preceding existence.
The beings of the human species, as well as all other beings, are susceptible of two sorts of motion: the one, that of the mass, by which an entire body, or some of its parts, are visibly transferred from one place to another; the other, internal and concealed, of some of which man is sensible, while some takes place without his knowledge, and is not even to be guessed at, but by the effect it outwardly produces. In a machine so extremely complex as man, formed by the combination of such a multiplicity of matter, so diversified in its properties, so different in its proportions, so varied in its modes of action, the motion necessarily becomes of the most complicated kind; its dullness, as well as its rapidity, frequently escapes the observation of those themselves, in whom it takes place.
Let us not, then, be surprised, if, when man would account to himself for his existence, for his manner of acting, finding so many obstacles to encounter, he invented such strange hypotheses to explain the concealed spring of his machine—if then this motion appeared to him, to be different from that of other bodies, he conceived an idea, that he moved and acted in a manner altogether distinct from the other beings in Nature. He clearly perceived that his body, as well as different parts of it, did act; but, frequently, he was unable to discover what brought them into action: from whence he received the impulse: he then conjectured he contained within himself a moving principle distinguished from his machine, which secretly gave an impulse to the springs which set this machine in motion; that moved him by its own natural energy; that consequently he acted according to laws totally distinct from those which regulated the motion of other beings: he was conscious of certain internal motion, which he could not help feeling; but how could he conceive, that this invisible motion was so frequently competent to produce such striking effects? How could he comprehend, that a fugitive idea, an imperceptible act of thought, was so frequently capacitated to bring his whole being into trouble and confusion? He fell into the belief, that he perceived within himself a substance distinguished from that self, endowed with a secret force; in which he supposed existed qualities distinctly differing from those, of either the visible causes that acted on his organs, or those organs themselves. He did not sufficiently understand, that the primitive cause which makes a stone fall, or his arm move, are perhaps as difficult of comprehension, as arduous to be explained, as those internal impulses, of which his thought or his will are the effects. Thus, for want of meditating Nature—of considering her under her true point of view—of remarking the conformity—of noticing the simultaneity, the unity of the motion of this fancied motive-power with that of his body—of his material organs—he conjectured he was not only a distinct being, but that he was set apart, with different energies, from all the other beings in Nature; that he was of a more simple essence having nothing in common with any thing by which he was surrounded; nothing that connected him with all that he beheld.
It is from thence has successively sprung his notions of SPIRITUALITY, IMMATERIALITY, IMMORTALITY; in short, all those vague unmeaning words he has invented by degrees, in order to subtilize and designate the attributes of the unknown power, which he believes he contains within himself; which he conjectures to be the concealed principle of all his visible actions when man once imbibes an idea that he cannot comprehend, he meditates upon it until he has given it a complete personification: Thus he saw, or fancied he saw, the igneous matter pervade every thing; he conjectured that it was the only principle of life and activity; he proceeded to embody it; he gave it his own form; called it JUPITER, and ended by worshipping this image of his own creation, as the power from whom he derived every good he experienced, every evil he sustained. To crown the bold conjectures he ventured to make on this internal motive-power, he supposed, that different from all other beings, even from the body that served to envelope it, it was not bound to undergo dissolution; that such was its perfect simplicity, that it could not be decomposed, nor even change its form; in short, that it was by its essence exempted from those revolutions to which he saw the body subjected, as well as all the compound beings with which Nature is filled.
Thus man, in his own ideas, became double; he looked upon himself as a whole, composed by the inconceivable assemblage of two different, two distinct natures, which have no point of analogy between themselves: he distinguished two substances in himself; one evidently submitted to the influence of gross beings, composed of coarse inert matter: this he called BODY;—the other, which he supposed to be simple, of a purer essence, was contemplated as acting from itself: giving motion to the body, with which it found itself so miraculously united: this he called SOUL, or SPIRIT; the functions of the one, he denominated physical, corporeal, material; the functions of the other he styled spiritual, intellectual. Man, considered relatively to the first, was termed the PHYSICAL MAN; viewed with relation to the last, he was designated the MORAL MAN. These distinctions, although adopted by the greater number of the philosophers of the present day, are, nevertheless, only founded on gratuitous suppositions. Man has always believed he remedied his ignorance of things, by inventing words to which he could never attach any true sense or meaning. He imagined he understood matter, its properties, its faculties, its resources, its different combinations, because he had a superficial glimpse of some of its qualities: he has, however, in reality, done nothing more than obscure the faint ideas he has been capacitated to form of this matter, by associating it with a substance much less intelligible than itself. It is thus, speculative man, in forming words, in multiplying beings, has only plunged himself into greater difficulties than those he endeavoured to avoid; and thereby placed obstacles to the progress of his knowledge: whenever he has been deficient of facts, he has had recourse to conjecture, which he quickly changed into fancied realities. Thus, his imagination, no longer guided by experience, hurried on by his new ideas, was lost, without hope of return, in the labyrinth of an ideal, of an intellectual world, to which he had himself given birth; it was next to impossible to withdraw him from this delusion, to place him in the right road, of which nothing but experience can furnish him the clue. Nature points out to man, that in himself, as well as in all those objects which act upon him, there is never more than matter endowed with various properties, diversely modified, that acts by reason of these properties: that man is an organized whole, composed of a variety of matter; that like all the other productions of Nature, he follows general and known laws, as well as those laws or modes of action which are peculiar to himself and unknown.
Thus, when it shall be inquired, what is man?
We say, he is a material being, organized after a peculiar manner; conformed to a certain mode of thinking—of feeling; capable of modification in certain modes peculiar to himself—to his organization—to that particular combination of matter which is found assembled in him.
If, again, it be asked, what origin we give to beings of the human species?
We reply, that, like all other beings, man is a production of Nature, who resembles them in some respects, and finds himself submitted to the same laws; who differs from them in other respects, and follows particular laws, determined by the diversity of his conformation.
If, then, it be demanded, whence came man?
We answer, our experience on this head does not capacitate us to resolve the question: but that it cannot interest us, as it suffices for us to know that man exists; that he is so constituted, as to be competent to the effects we witness.
But it will be urged, has man always existed? Has the human species existed from all eternity; or is it only an instantaneous production of Nature? Have there been always men like ourselves? Will there always be such? Have there been, in all times, males and females? Was there a first man, from whom all others are descended? Was the animal anterior to the egg, or did the egg precede the animal? Is this species without beginning? Will it also be without end? The species itself, is it indestructible, or does it pass away like its individuals? Has man always been what he now is; or has he, before he arrived at the state in which we see him, been obliged to pass under an infinity of successive developements? Can man at last flatter himself with having arrived at a fixed being, or must the human species again change? If man is the production of Nature, it will perhaps be asked, Is this Nature competent to the production of new beings, to make the old species disappear? Adopting this supposition, it may be inquired, why Nature does not produce under our own eyes new beings—new species?
It would appear on reviewing these questions, to be perfectly indifferent, as to the stability of the argument we have used, which side was taken; that, for want of experience, hypothesis must settle a curiosity that always endeavours to spring forward beyond the boundaries prescribed to our mind. This granted, the contemplator of Nature will say, that he sees no contradiction, in supposing the human species, such as it is at the present day, was either produced in the course of time, or from all eternity: he will not perceive any advantage that can arise from supposing that it has arrived by different stages, or successive developements, to that state in which it is actually found. Matter is eternal, it is necessary, but its forms are evanescent and contingent. It may be asked of man, is he any thing more than matter combined, of which the former varies every instant?
Notwithstanding, some reflections seem to favor the supposition, to render more probable the hypothesis, that man is a production formed in the course of time; who is peculiar to the globe he inhabits, who is the result of the peculiar laws by which it is directed; who, consequently, can only date his formation as coeval with that of his planet. Existence is essential to the universe, or the total assemblage of matter essentially varied that presents itself to our contemplation; the combinations, the forms, however, are not essential. This granted, although the matter of which the earth is composed has always existed, this earth may not always have had its present form—its actual properties; perhaps it may be a mass detached in the course of time from some other celestial body;—perhaps it is the result of the spots, or those encrustations which astronomers discover in the sun's disk, which have had the faculty to diffuse themselves over our planetary system;—perhaps the sphere we inhabit may be an extinguished or a displaced comet, which heretofore occupied some other place in the regions of space;—which, consequently, was then competent to produce beings very different from those we now behold spread over its surface; seeing that its then position, its nature, must have rendered its productions different from those which at this day it offers to our view.
Whatever may be the supposition adopted, plants, animals, men, can only be regarded as productions inherent in and natural to our globe, in the position and in the circumstances in which it is actually found: these productions it would be reasonable to infer would be changed, if this globe by any revolution should happen to shift its situation. What appears to strengthen this hypothesis, is, that on our ball itself, all the productions vary, by reason of its different climates: men, animals, vegetables, minerals, are not the same on every part of it: they vary sometimes in a very sensible manner, at very inconsiderable distances. The elephant is indigenous to, or native of the torrid zone: the rein deer is peculiar to the frozen climates of the North; Indostan is the womb that matures the diamond; we do not find it produced in our own country: the pine-apple grows in the common atmosphere of America; in our climate it is never produced in the open ground, never until art has furnished a sun analogous to that which it requires—the European in his own climate finds not this delicious fruit. Man in different climates varies in his colour, in his size, in his conformation, in his powers, in his industry, in his courage, and in the faculties of his mind. But, what is it that constitutes climate? It is the different position of parts of the same globe, relatively to the sun; positions that suffice to make a sensible variety in its productions.
There is, then, sufficient foundation to conjecture that if by any accident our globe should become displaced, all its productions would of necessity be changed; seeing that causes being no longer the same, or no longer acting after the same manner, the effects would necessarily no longer be what they now are, all productions, that they may be able to conserve themselves, or maintain their actual existence, have occasion to co-order themselves with the whole from which they have emanated. Without this they would no longer be in a capacity to subsist: it is this faculty of co-ordering themselves,—this relative adaption, which is called the ORDER OF THE UNIVERSE: the want of it is called CONFUSION. Those productions which are treated as MONSTROUS, are such as are unable to co-order themselves with the general or particular laws of the beings who surround them, or with the whole in which they find themselves placed: they have had the faculty in their formation to accommodate themselves to these laws; but these very laws are opposed to their perfection: for this reason they are unable to subsist. It is thus that by a certain analogy of conformation, which exists between animals of different species, mules are easily produced; but these mules, unable to co-order themselves with the beings that surround them, are not able to reach perfection, consequently cannot propagate their species. Man can live only in air, fish only in water: put the man into the water, the fish into the air, not being able to co-order themselves with the fluids which surround them, these animals will quickly be destroyed. Transport by imagination, a man from our planet into SATURN, his lungs will presently be rent by an atmosphere too rarified for his mode of being, his members will be frozen with the intensity of the cold; he will perish for want of finding elements analogous to his actual existence: transport another into MERCURY, the excess of heat, beyond what his mode of existence can bear, will quickly destroy him.
Thus, every thing seems to authorise the conjecture, that the human species is a production peculiar to our sphere, in the position in which it is found: that when this position may happen to change, the human species will, of consequence, either be changed or will be obliged to disappear; seeing that there would not then be that with which man could co-order himself with the whole, or connect himself with that which can enable him to subsist. It is this aptitude in man to co-order himself with the whole, that not only furnishes him with the idea of order, but also makes him exclaim "whatever is, is right;" whilst every thing is only that which it can be, as long as the whole is necessarily what it is; whilst it is positively neither good nor bad, as we understand those terms: it is only requisite to displace a man, to make him accuse the universe of confusion.
These reflections would appear to contradict the ideas of those, who are willing to conjecture that the other planets, like our own, are inhabited by beings resembling ourselves. But if the LAPLANDER differs in so marked a manner from the HOTTENTOT, what difference ought we not rationally to suppose between an inhabitant of our planet and one of SATURN or of VENUS?
However it may be, if we are obliged to recur by imagination to the origin of things, to the infancy of the human species, we may say that it is probable that man was a necessary consequence of the disentangling of our globe; or one of the results of the qualities, of the properties, of the energies, of which it is susceptible in its present position—that he was born male and female—that his existence is co-ordinate with that of the globe, under its present position—that as long as this co-ordination shall subsist, the human specie will conserve himself, will propagate himself, according to the impulse, after the primitive laws, which he has originally received—that if this co-ordination should happen to cease; if the earth, displaced, should cease to receive the same impulse, the same influence, on the part of those causes which actually act upon it, or which give it energy; that then the human species would change, to make place for new beings, suitable to co-order themselves with the state that should succeed to that which we now see subsist.
In thus supposing the changes in the position of our globe, the primitive man did, perhaps, differ more from the actual man, than the quadruped differs from the insect. Thus man, the same as every thing else that exists on our planet, as well as in all the others, may be regarded as in a state of continual vicissitude: thus the last term of the existence of man is to us as unknown and as indistinct as the first: there is, therefore, no contradiction in the belief that the species vary incessantly—that to us it is as impossible to know what he will become, as to know what he has been.
With respect to those who may ask why Nature does not produce new beings? we may enquire of them in turn, upon what foundation they suppose this fact? What it is that authorizes them to believe this sterility in Nature? Know they if, in the various combinations which she is every instant forming, Nature be not occupied in producing new beings, without the cognizance of these observers? Who has informed them that this Nature is not actually assembling, in her immense elaboratory, the elements suitable to bring to light, generations entirely new, that will have nothing in common with those of the species at present existing? What absurdity then, or what want of just inference would there be, to imagine that the man, the horse, the fish, the bird, will be no more? Are these animals so indispensably requisite to Nature, that without them she cannot continue her eternal course? Does not all change around us? Do we not ourselves change? Is it not evident that the whole universe has not been, in its anterior eternal duration, rigorously the same that it now is? that it is impossible, in its posterior eternal duration, it can be rigidly in the same state that it now is for a single instant? How, then, pretend to divine that, to which the infinite succession of destruction, of reproduction, of combination, of dissolution, of metamorphosis, of change, of transposition, may be able eventually to conduct it by their consequence? Suns encrust themselves, and are extinguished; planets perish and disperse themselves in the vast plains of air; other suns are kindled, and illumine their systems; new planets form themselves, either to make revolutions round these suns, or to describe new routes; and man, an infinitely small portion of the globe, which is itself but an imperceptible point in the immensity of space, vainly believes it is for himself this universe is made; foolishly imagines he ought to be the confident of Nature; confidently flatters himself he is eternal: and calls himself KING OF THE UNIVERSE!!!
O man! wilt thou never conceive, that thou art but an ephemeron? All changes in the great macrocosm: nothing remains the same an instant, in the planet thou inhabitest: Nature contains no one constant form, yet thou pretendest thy species can never disappear; that thou shalt be exempted from the universal law, that wills all shall experience change! Alas! In thy actual being, art not thou submitted to continual alterations? Thou, who in thy folly, arrogantly assumest to thyself the title of KING OF NATURE! Thou, who measurest the earth and the heavens! Thou, who in thy vanity imaginest, that the whole was made, because thou art intelligent! There requires but a very slight accident, a single atom to be displaced, to make thee perish; to degrade thee; to ravish from thee this intelligence of which thou appearest so proud.
If all the preceding conjectures be refused by those opposed to us; if it be pretended that Nature acts by a certain quantum of immutable and general laws; if it be believed that men, quadrupeds, fish, insects, plants, are from all eternity, and will remain eternally, what they now are: if I say it be contended, that from all eternity the stars have shone, in the immense regions of space, have illuminated the firmament; if it be insisted, we must no more demand why man is such as he appears, then ask why Nature is such as we behold her, or why the world exists? We are no longer opposed to such arguments. Whatever may be the system adopted, it will perhaps reply equally well to the difficulties with which our opponents endeavour to embarrass the way: examined closely, it will be perceived they make nothing against those truths, which we have gathered from experience. It is not given to man to know every thing—it is not given him to know his origin—it is not given him to penetrate into the essence of things, nor to recur to first principles—but it is given him, to have reason, to have honesty, to ingenuously allow he is ignorant of that which he cannot know, and not to substitute unintelligible words, absurd suppositions, for his uncertainty. Thus, we say to those, who to solve difficulties far above their reach, pretend that the human species descended from a first man and a first woman, created diversely according to different creeds;—that we have some ideas of Nature, but that we have none of creation;—that the human mind is incapable of comprehending the period when all was nothing;—that to use words we cannot understand, is only in other terms to acknowledge our ignorance of the powers of Nature;—that we are unable to fathom the means by which she has been capacitated to produce the phenomena we behold.
Let us then conclude, that man has no just, no solid reason to believe himself a privileged being in Nature; because he is subject to the same vicissitudes, as all her other productions. His pretended prerogatives have their foundation in error, arising from mistaken opinions concerning his existence. Let him but elevate himself by his thoughts above the globe he inhabits, he will look upon his own species with the same eyes he does all other beings in Nature: He will then clearly perceive that in the same manner that each tree produces its fruit, by reason of its energies, in consequence of its species: so each man acts by reason of his particular energy; that he produces fruit, actions, works, equally necessary: he will feel that the illusion which he anticipates in favour of himself, arises from his being, at one and the same time, a spectator and a part of the universe. He will acknowledge, that the idea of excellence which he attaches to his being, has no other foundation than his own peculiar interest; than the predilection he has in favour of himself—that the doctrine he has broached with such seeming confidence, bottoms itself on a very suspicious foundation, namely IGNORANCE and SELF-LOVE.
CHAP. VII.
The Soul and the Spiritual System.
Man, after having gratuitously supposed himself composed of two distinct independent substances, that have no common properties, relatively with each other; has pretended, as we have seen, that that which actuated him interiorly, that motion which is invisible, that impulse which is placed within himself, is essentially different from those which act exteriorly. The first he designated, as we have already said, by the name of a SPIRIT or a SOUL. If however it be asked, what is a spirit? The moderns will reply, that the whole fruit of their metaphysical researches is limited to learning that this motive-power, which they state to be the spring of man's action, is a substance of an unknown nature; so simple, so indivisible, so deprived of extent, so invisible, so impossible to be discovered by the senses, that its parts cannot be separated, even by abstraction or thought. The question then arises, how can we conceive such a substance, which is only the negation of every thing of which we have a knowledge? How form to ourselves an idea of a substance, void of extent, yet acting on our senses; that is to say, on those organs which are material, which have extent? How can a being without extent be moveable; how put matter in action? How can a substance devoid of parts, correspond successively with different parts of space? But a very cogent question presents itself on this occasion: if this distinct substance that is said to form one of the component parts of man, be really what it is reported, and if it be not, it is not what it is described; if it be unknown, if it be not pervious to the senses; if it be invisible, by what means did the metaphysicians themselves become acquainted with it? How did they form ideas of a substance, that taking their own account of it, is not, under any of its circumstances, either directly or by analogy, cognizable to the mind of man? If they could positively achieve this, there would no longer be any mystery in Nature: it would be as easy to conceive the time when all was nothing, when all shall have passed away, to account for the production of every thing we behold, as to dig in a garden or read a lecture.—Doubt would vanish from the human species; there could no longer be any difference of opinion, since all must necessarily be of one mind on a subject so accessible to every enquirer.
But it will be replied, the materialist himself admits, the natural philosophers of all ages have admitted, elements and atoms, beings simple and indivisible, of which bodies are composed:—granted; they have no more: they have also admitted that many of these atoms, many of these elements, if not all, are unknown to them: nevertheless, these simple beings, these atoms of the materialist, are not the same thing with the spirit, or the soul of the metaphysician. When the natural philosopher talks of atoms—when he describes them as simple beings, he indicates nothing more than that they are homogeneous, pure, without mixture: but then he allows that they have extent, consequently parts, are separable by thought, although no other natural agent with which he is acquainted is capable of dividing them: that the simple beings of this genus are susceptible of motion—can impart action—receive impulse—are material—are placed in Nature—are indestructible;—that consequently, if he cannot know them from themselves, he can form some idea of them by analogy: thus he has done that intelligibly, which the metaphysician would do unintelligibly: the latter, with a view to render man immortal, finding difficulties to his wish, from seeing that the body decayed—that it has submitted to the great, the universal law—has, to solve the difficulty, to remove the impediment, given him a soul, distinct from the body, which he says is exempted from the action of the general law: to account for this, he has called it a spiritual being, whose properties are the negation of all known properties, consequently inconceivable: had he, however, had recourse to the atoms of the former—had he made this substance the last possible term of the division of matter—it would at least have been intelligible; it would also have been immortal, since, according to the reasonings of all men, whether metaphysicians, theologians, or natural philosophers, an atom is an indestructible element, that must exist to all eternity.
All men are agreed in this position, that motion is the successive change of the relations of one body with other bodies, or with the different parts of space. If that which is called spirit be susceptible of communicating or receiving motion—if it acts—if it gives play to the organs of body—to produce these effects, it necessarily follows that this being changes successively its relation, its tendency, its correspondence, the position of its parts, either relatively to the different points of space, or to the different organs of the body which it puts in action: but to change its relation with space, with the organs to which it gives impulse, it follows of necessity that this spirit most have extent, solidity, consequently distinct parts: whenever a substance possesses these qualities, it is what we call MATTER, it can no longer be regarded as a simple pure being, in the sense attached to it by the moderns, or by theologians.
Thus it will be seen, that those who, to conquer insurmountable difficulties, have supposed in man an immaterial substance, distinguished from his body, have not thoroughly understood themselves; indeed they have done nothing more than imagined a negative quality, of which they cannot have any correct idea: matter alone is capable of acting on our senses; without this action nothing would be capable of making itself known to us. They have not seen that a being without extent is neither in a capacity to move itself, nor has the capability of communicating motion to the body; since such a being, having no parts, has not the faculty of changing its relation, or its distance, relatively to other bodies, nor of exciting motion in the human body, which is itself material. That which is called our soul moves itself with us; now motion is a property of matter—this soul gives impulse to the arm; the arm, moved by it, makes an impression, a blow, that follows the general law of motion: in this case, the force remaining the same, if the mass was two-fold, the blow should be double. This soul again evinces its materiality in the invincible obstacles it encounters on the part of the body. If the arm be moved by its impulse when nothing opposes it, yet this arm can no longer move, when it is charged with a weight beyond its strength. Here then is a mass of matter that annihilates the impulse given by a spiritual cause, which spiritual cause having no analogy with matter, ought not to find more difficulty in moving the whole world, than in moving a single atom, nor an atom, than the universe. From this, it is fair to conclude, such a substance is a chimera—a being of the imagination. That it required a being differently endowed, differently constituted, to set matter in motion—to create all the phenomena we behold: nevertheless, it is a being the metaphysicians have made the contriver, the Author of Nature. As man, in all his speculations, takes himself for the model, he no sooner imagined a spirit within himself, than giving it extent, he made it universal; then ascribed to it all those causes with which his ignorance prevents him from becoming acquainted, thus he identified himself with the Author of Nature—then availed himself of the supposition to explain the connection of the soul with the body: his self-complacency prevented his perceiving that he was only enlarging the circle of his errors, by pretending to understand that which it is more than possible he will never be permitted to know; his self-love prevented him from feeling, that whenever he punished another for not thinking as he did, that he committed the greatest injustice, unless he was satisfactorily able to prove that other wrong, and himself right: that if he himself was obliged to have recourse to hypothesis—to gratuitous suppositions, whereon to found his doctrine, that from the very fallibility of his nature, these might be erroneous: thus GALLILEO was persecuted, because the metaphysicians, the theologians of his day, chose to make others believe what it was evident they did not themselves understand.
As soon as I feel an impulse, or experience motion, I am under the necessity to acknowledge extent, solidity, density, impenetrability in the substance I see move, or from which I receive impulse: thus, when action is attributed to any cause whatever, I am obliged to consider it MATERIAL. I may be ignorant of its individual nature, of its mode of action, or of its generic properties; but I cannot deceive myself in general properties, which are common to all matter: this ignorance will only be increased, when I shall take that for granted of a being, of which from that moment I am precluded by what I admit from forming any idea, which moreover deprives it completely either of the faculty of moving itself, giving an impulse, or acting. Thus, according to the received idea of the term, a spiritual substance that moves itself, that gives motion to matter, and that acts, implies a contradiction, that necessarily infers a total impossibility.
The partizans of spirituality believe they answer the difficulties they have accumulated, by asserting that "the soul is entire—is whole under each point of its extent." If an absurd answer will solve difficulties, they certainly have done it. But let us examine this reply:—it will be found that this indivisible part which is called soul, however insensible or however minute, must yet remain something: then an infinity of unextended substances, or the same substance having no dimensions, repeated an infinity of times, would constitute a substance that has extent: this cannot be what they mean, because according to this principle, the human soul would then be as infinite as the Author of Nature; seeing that they have stated this to be a being without extent, who is an infinity of times whole in each part of the universe. But when there shall appear as much solidity in the answer as there is a want of it, it must be acknowledged that in whatever manner the spirit or the soul finds itself in its extent, when the body moves forward the soul does not remain behind; if so, it has a quality in common with the body, peculiar to matter; since it is conveyed from place to place jointly with the body. Thus, when even the soul should be admitted to be immaterial, what conclusion must be drawn? Entirely submitted to the motion of the body, without this body it would remain dead and inert. This soul would only be part of a two-fold machine, necessarily impelled forward by a concatenation, or connection with the whole. It would resemble a bird, which a child conducts at its pleasure, by the string with which it is bound.
Thus, it is for want of consulting experience, by not attending to reason, that man has darkened his ideas upon the concealed principle of his motion. If, disentangled from prejudice—if, destitute of gratuitous suppositions—if, throwing aside error, he would contemplate his soul, or the moving principle that acts within him, he would be convinced that it forms a part of its body, that it cannot be distinguished from it, but by abstraction; that it is only the body itself, considered relatively with some of its functions, or with those faculties of which its nature, or its peculiar organization, renders it susceptible:—he will perceive that this soul is obliged to undergo the same changes as the body; that it is born with it; that it expands itself with it; that like the body, it passes through a state of infancy, a period of weakness, a season of inexperience; that it enlarges itself, that it strengthens itself, in the same progression; that like the body, it arrives at an adult age or reaches maturity; that it is then, and not till then, it obtains the faculty of fulfilling certain functions; that it is in this stage, and in no other, that it enjoys reason; that it displays more or less wit, judgment, and manly activity; that like the body, it is subject to those vicissitudes which exterior causes obliges it to undergo by their influence; that, conjointly with the body, it suffers, enjoys, partakes of its pleasures, shares its pains, is sound when the body is healthy, and diseased when the body is oppressed with sickness; that like the body, it is continually modified by the different degrees of density in the atmosphere; by the variety of the seasons, and by the various properties of the aliments received into the stomach: in short, he would be obliged to acknowledge that at some periods it manifests visible signs of torpor, stupefaction, decrepitude, and death.
In despite of this analogy, or rather this continual identity, of the soul with the body, man has been desirous of distinguishing their essence; he has therefore made the soul an inconceivable being: but in order that he might form to himself some idea of it, he was, notwithstanding, obliged to have recourse to material beings, and to their manner of acting. The word spirit, therefore, presents to the mind no other ideas than those of breathing, of respiration, of wind. Thus, when it is said the soul is a spirit, it really means nothing more than that its mode of action is like that of breathing: which though invisible in itself, or acting without being seen, nevertheless produces very visible effects. But breath, it is acknowledged, is a material cause; it is allowed to be air modified; it is not, therefore, a simple or pure substance, such as the moderns designate under the name of SPIRIT.
It is rather singular that in the Hebrew, the Greek, and the Latin, the synonymy, or corresponding term for spirit should signify breath. The metaphysicians themselves can best say why they have adopted such a word, to designate the substance they have distinguished from matter: some of them, fearful they should not have distinct beings enough, have gone farther, and compounded man of three substances, BODY, SOUL, and INTELLECT.
Although the word spirit is so very ancient among men, the sense attached to it by the moderns is quite new: the idea of spirituality, as admitted at this day, is a recent production of the imagination. Neither PYTHAGORAS nor PLATO, however heated their brain, however decided their taste for the marvellous, appear to have understood by spirit an immaterial substance, or one without extent, devoid of parts; such as that of which the moderns have formed the human soul, the concealed author of motion. The ancients, by the word spirit, were desirous to define matter of an extreme subtilty, of a purer quality than that which acted grossly on our senses. In consequence, some have regarded the soul as an ethereal substance; others as igneous matter; others again have compared it to light. DEMOCRITUS made it consist in motion, consequently gave it a manner of existence. ARISTOXENES, who was himself a musician, made it harmony. ARISTOTLE regarded the soul as the moving faculty, upon which depended the motion of living bodies.
The earliest doctors of Christianity had no other idea of the soul, than that it was material. TERTULLIAN, ARNOBIUS, CLEMENT of ALEXANDRIA, ORIGEN, SAINT JUSTIN, IRENAEUS, have all of them discoursed upon it; but have never spoken of it other than as a corporeal substance—as matter. It was reserved for their successors at a great distance of time, to make the human soul and the soul of the world pure spirits; that is to say, immaterial substances, of which it is impossible they could form any accurate idea: by degrees this incomprehensible doctrine of spirituality, conformable without doubt to the views of those who make it a principle to annihilate reason, prevailed over the others: But it might be fairly asked, if the pretended proofs of this doctrine owe themselves to a man, who on a much more comprehensible point has been proved in error; if, on that which time has shewn was accessible to man's reason, the great champion in support of this dogma was deceived; are we not bound to examine, with the most rigorous investigation, the reasonings, the evidence, of one who was the decided, the proven child of enthusiasm and error? Yet DESCARTES, to whose sublime errors the world is indebted for the Newtonian system, although before him the soul had been considered spiritual, was the first who established that, "that which thinks ought to be distinguished from matter;" from whence he concludes rather hastily, that the soul, or that which thinks in man, is a spirit; or a simple indivisible substance. Perhaps it would have been more logical, more consistent with reason, to have said, since man, who is matter, who has no idea but of matter, enjoys the faculty of thought, matter can think; that is, it is susceptible of that particular modification called thought.
However this may be, this doctrine was believed divine, supernatural, because it was inconceivable to man. Those who dared believe even that which was believed before; namely, that the soul was material, were held as rash inconsiderate madmen, or else treated as enemies to the welfare and happiness of the human race. When man had once renounced experience; when he had abjured his reason; when he had joined the banner of this enthusiastic novelty; he did nothing more, day after day, than subtilize the delirium, the ravings of his imagination: he pleased himself by continually sinking deeper into the most unfathomable depths of error: he felicitated himself on his discoveries; on his pretended knowledge; in an exact ratio as his understanding became enveloped in the mists of darkness, environed with the clouds of ignorance. Thus, in consequence of man's reasoning upon false principles; of having relinquished the evidence of his senses; the moving principle within him, the concealed author of motion, has been made a mere chimera, a mere being of the imagination, because he has divested it of all known properties; because he has attached to it nothing but properties which, from the very nature of his existence, he is incapacitated to comprehend.
The doctrine of spirituality, such as it now exists, offers nothing but vague ideas; or rather is the absense of all ideas. What does it present to the mind, but a substance which possesses nothing of which our senses enable us to have a knowledge? Can it be truth that a man is able to figure to himself a being not material, having neither extent nor parts, which, nevertheless, acts upon matter without having any point of contact, any kind of analogy with it; and which itself receives the impulse of matter by means of material organs, which announce to it the presence of other beings? Is it possible to conceive the union of the soul with the body; to comprehend how this material body can bind, enclose, constrain, determine a fugitive being which escapes all our senses? Is it honest, is it plain dealing, to solve these difficulties, by saying there is a mystery in them; that they are the effects of a power, more inconceivable than the human soul; than its mode of acting, however concealed from our view? When to resolve these problems, man is obliged to have recourse to miracles or to make the Divinity interfere, does he not avow his own ignorance? When, notwithstanding the ignorance he is thus obliged to avow by availing himself of the divine agency, he tells us, this immaterial substance, this soul, shall experience the action of the element of fire, which he allows to be material; when he confidently says this soul shall be burnt; shall suffer in purgatory; have we not a right to believe, that either he has a design to deceive us, or else that he does not himself understand that which he is so anxious we should take upon his word?
Let us not then be surprised at those subtile hypotheses, as ingenious as they are unsatisfactory, to which theological prejudice has obliged the most profound modern speculators to recur; when they have undertaken to reconcile the spirituality of the soul, with the physical action of material beings, on this incorporeal substance; its re-action upon these beings; its union with the body. When the human mind permits itself to be guided by authority without proof, to be led forward by enthusiasm; when it renounces the evidence of its senses; what can it do more than sink into error? Let those who doubt this, read the metaphysical romances of LEIBNITZ, DESCARTES, MALEBRANCHE, CUDWORTH, and many others: let them coolly examine the ingenious, but fanciful systems entitled the pre-established harmony of occasional causes; physical pre-motion, &c.
If man wishes to form to himself clear, perspicuous ideas of his soul, let him throw himself back on his experience—let him renounce his prejudices—let him avoid theological conjecture—let him tear the bandages which he has been taught to think necessary, but with which he has been blind-folded, only to confound his reason. If it be wished to draw man to virtue, let the natural philosopher, let the anatomist, let the physician, unite their experience; let them compare their observations, in order to show what ought to be thought of a substance, so disguised, so hidden by absurdities, as not easily to be known. Their discoveries may perhaps teach moralists the true motive-power that ought to influence the actions of man—legislators, the true motives that should actuate him, that should excite him to labour to the welfare of society—sovereigns, the means of rendering their subjects truly happy; of giving solidity to the power of the nations committed to their charge. Physical souls have physical wants, and demand physical happiness. These are real, are preferable objects, to that variety of fanciful chimeras, each in its turn giving place to the other, with which the mind of man has been fed during so many ages. Let us, then, labour to perfect the morality of man; let us make it agreeable to him; let us excite in him an ardent thirst for its purity: we shall presently see his morals become better, himself become happier; his soul become calm and serene; his will determined to virtue, by the natural, by the palpable motives held out to him. By the diligence, by the care which legislators shall bestow on natural philosophy, they will form citizens of sound understandings; robust and well constituted; who, finding themselves happy, will be themselves accessary to that useful impulse so necessary for their soul. When the body is suffering, when nations are unhappy, the soul cannot be in a proper state. Mens sana in corpore sano, a sound mind in a sound body, will be always able to make a good citizen.
The more man reflects, the more he will be convinced that the soul, very far from being distinguished from the body, is only the body itself, considered relatively to some of its functions, or to some of the modes of existing or acting, of which it is susceptible whilst it enjoys life. Thus, the soul is man, considered relatively to the faculty he has of feeling, of thinking, of acting in a mode resulting from his peculiar nature; that is to say, from his properties, from his particular organization: from the modifications, whether durable or transitory, which the beings who act upon him cause his machine to undergo.
Those who have distinguished the soul from the body, appear only to have distinguished their brain from themselves. Indeed, the brain is the common center, where all the nerves, distributed through every part of the body, meet and blend themselves: it is by the aid of this interior organ that all those operations are performed which are attributed to the soul: it is the impulse, or the motion, communicated to the nerve, which modifies the brain: in consequence, it re-acts, or gives play to the bodily organs; or rather it acts upon itself, and becomes capable of producing within itself a great variety of motion, which has been designated intellectual faculties.
From this it may be seen that some philosophers have been desirous to make a spiritual substance of the brain. It is evidently nothing but ignorance that has given birth to and accredited this system, which embraces so little, either of the natural or the rational. It is from not having studied himself, that man has supposed he was compounded with an agent, essentially different from his body: in examining this body, he will find that it is quite useless to recur to hypothesis for the explanation of the various phenomena it presents to his contemplation; that hypothesis can do nothing more than lead him out of the right road to the information after which he seeks. What obscures this question, arises from this, that man cannot see himself: indeed, for this purpose, that would be requisite which is impossible; namely, that he could he at one and the same moment both within and without himself: he may be compared to an Eolian harp, that issues sounds of itself, and should demand what it is that causes it to give them forth? It does not perceive that the sensitive quality of its chords causes the air to brace them; that being so braced, it is rendered sonorous by every gust of wind with which it happens to come in contact.
When a theologian, obstinately bent on admitting into man two substances essentially different, is asked why he multiplies beings without necessity? he will reply, because "thought cannot be a property of matter." If, then, it be enquired of him, cannot God give to matter the faculty of thought? he will answer, "no! seeing that God cannot do impossible things!" According to his principles, it is as impossible that spirit or thought can produce matter, as it is impossible that matter can produce spirit or thought: it might, therefore, be concluded against him, that the world was not made by a spirit, any more than a spirit was made by the world. But in this case, does not the theologian, according to his own assertion, acknowledge himself to be the true atheist? Does he not, in fact, circumscribe the attributes of the Deity, and deny his power, to suit his own purpose? Yet these men demand implicit belief in doctrines, which they are obliged to maintain by the most contradictory assertions.
The more experience we collect, the more we shall be convinced that the word spirit, in its present received usage, conveys no one sense that is tangible, either to ourselves or to those that invented it; consequently cannot be of the least use, either in physics or morals. What modern metaphysicians believe and understand by the word, is nothing more than an occult power, imagined to explain occult qualities and actions, but which, in fact, explains nothing. Savage nations admit of spirits, to account to themselves for those effects, which to them appear marvellous, as long as their ignorance knows not the cause to which they ought to be attributed. In attributing to spirits the phenomena of Nature, as well as those of the human body, do we, in fact, do any thing more than reason like savages? Man has filled Nature with spirits, because he has almost always been ignorant of the true causes of those effects by which he was astonished. Not being acquainted with the powers of Nature, he has supposed her to be animated by a great spirit: not understanding the energy of the human frame, he has in like manner conjectured it to be animated by a minor spirit: from this it would appear, that whenever he wished to indicate the unknown cause of a phenomena, he knew not how to explain in a natural manner, he had recourse to the word spirit. In short, spirit was a term by which he solved all his doubts, and cleared up his ignorance to himself. It was according to these principles that when the AMERICANS first beheld the terrible effects of gunpowder, they ascribed the cause to wrathful spirits, to their enraged divinities: it was by adopting these principles, that our ancestors believed in a plurality of gods, in ghosts, in genii, &c. Pursuing the same track, we ought to attribute to spirits gravitation, electricity, magnetism, &c. &c. It is somewhat singular, that priests have in all ages so strenuously upheld those systems which time has exploded; that they have appeared to be either the most crafty or the most ignorant of men. Where are now the priests of Apollo, of Juno, of the Sun, and a thousand others? Yet these are the men, who in all times have persecuted those who have been the first to give natural explanations of the phenomena of Nature, as witness ANAXAGORAS, ARISTOTLE, GALLILEO, DESCARTES, &c. &c.
CHAP. VIII.
The Intellectual Faculties derived from the Faculty of Feeling.
To convince ourselves that the faculties called intellectual, are only certain modes of existence, or determinate manners of acting, which result from the peculiar organization of the body, we have only to analyze them; we shall then see that all the operations which are attributed to the soul, are nothing more than certain modifications of the body; of which a substance that is without extent, that has no parts, that is immaterial, is not susceptible.
The first faculty we behold in the living man, and that from which all his others flow, is feeling: however inexplicable this faculty may appear, on a first view, if it be examined closely, it will be found to be a consequence of the essence, or a result of the properties of organized beings; the same as gravity, magnetism, elasticity, electricity, &c. result from the essence or nature of some others. We shall also find these last phenomena are not less inexplicable than that of feeling. Nevertheless, if we wish to define to ourselves a clear and precise idea of it, we shall find that feeling is a particular manner of being moved—a mode of receiving an impulse peculiar to certain organs of animated bodies, which is occasioned by the presence of a material object that acts upon these organs, and transmit the impulse or shock to the brain.
Man only feels by the aid of nerves dispersed through his body; which is itself, to speak correctly, nothing more than a great nerve; or may be said to resemble a large tree, of which the branches experience the action of the root, communicated through the trunk. In man the nerves unite and lose themselves in the brain; that intestine is the true seat of feeling: like the spider in the centre of his web, it is quickly warned of all the changes that happen to the body, even at the extremities to which it sends its filaments and branches. Experience enables us to ascertain, that man ceases to feel in those parts of his body of which the communication with the brain is intercepted; he feels very little, or not at all, whenever this organ is itself deranged or affected in too lively a manner. A proof of this is afforded in the transactions of the Royal Academy of Sciences at Paris: they inform us of a man who had his scull taken off, in the room of which his brain was recovered with skin; in proportion as a pressure was made by the hand on his brain, the man fell into a kind of insensibility, which deprived him of all feeling. BARTOLIN says, the brain of a man is twice as big as that of an ox. This observation had been already made by ARISTOTLE. In the dead body of an idiot dissected by WILLIS, the brain was found smaller than ordinary: he says the greatest difference he found between the parts of the body of this idiot, and those of wiser men, was, that the plexus of the intercostal nerves, which is the mediator between the brain and the heart, was extremely small, accompanied by a less number of nerves than usual. According to WILLIS, the ape is, of all animals, that which has the largest brain, relatively to his size: he is also, after man, that which has the most intelligence: this is further confirmed, by the name he bears in the soil, to which he is indigenous, which is ourang outang, or the man beast. There is, therefore, every reason to believe that it is entirely in the brain, that consists the difference, that is found not only between man and beasts, but also between the man of wit, and the fool: between the thinking man, and he who is ignorant; between the man of sound understanding, and the madman: a multitude of experience, serves to prove, that those persons who are most accustomed to use their intellectual faculties, have their brain more extended than others: the same has been remarked of watermen, that they have arms much longer than other men.
However this may be, the sensibility of the brain, and all its parts, is a fact: if it be asked, whence comes this property? We shall reply, it is the result of an arrangement, of a combination, peculiar to the animal: it is thus that milk, bread, wine, change themselves in the substance of man, who is a sensible being: this insensible matter becomes sensible, in combining itself with a sensible whole. Some philosophers think that sensibility is a universal quality of matter: in this case, it would be useless to seek from whence this property is derived, as we know it by its effects. If this hypothesis be admitted, in like manner as two kinds of motion are distinguished in Nature, the one called live force, the other dead, or inert force, two sorts of sensibility will be distinguished, the one active or alive, the other inert or dead. Then to animalize a substance, is only to destroy the obstacles that prevent its being active or sensible. In fact, sensibility is either a quality which communicates itself like motion, and which is acquired by combination; or this sensibility is a property inherent in all matter: in both, or either case, an unextended being, without parts, such as the human soul is said to be, can neither be the cause of it nor submitted to its operation; but we may fairly conclude, that all the parts of Nature enjoy the capability to arrive at animation; the obstacle is only in the state, not in the quality. Life is the perfection of Nature: she has no parts which do not tend to it—which do not attain it by the same means. Life in an insect, a dog, a man, has no other difference, than that this act is more perfect, relatively to ourselves in proportion to the structure of the organs: if, therefore, it be asked, what is requisite to animate a body? we reply, it needs no foreign aid; it is sufficient that the power of Nature be joined to its organization.
The conformation, the arrangement, the texture, the delicacy of the organs, as well exterior as interior, which compose men and animals, render their parts extremely mobile, or make their machine susceptible of being moved with great facility. In a body, which is only a heap of fibres, a mass of nerves, contiguous one to the other, united in a common center, always ready to act; in a whole, composed of fluids and solids, of which the parts are in equilibrium, the smallest touching each other, are active in their motion, communicating reciprocally, alternately and in succession, the impression, oscillations, and shocks they receive; in such a composition, it is not surprising that the slightest impulse propagates itself with celerity; that the shocks excited in its remotest parts, make themselves quickly felt in the brain, whose delicate texture renders it susceptible of being itself very easily modified. Air, fire, water, agents the most inconstant, possessing the most rapid motion, circulate continually in the fibres, incessantly penetrate the nerves: without doubt these contribute to that incredible celerity with which the brain is acquainted with what passes at the extremities of the body.
Notwithstanding the great mobility with which man's organization renders him susceptible, although exterior as well as interior causes are continually acting upon him, he does not always feel in a distinct, in a decided manner, the impulse given to his senses: indeed, he does not feel it, until it has produced some change, or given some shock to his brain. Thus, although completely environed by air, he does not feel its action, until it is so modified, as to strike with a sufficient degree of force on his organs; to penetrate his skin, through which his brain is warned of its presence. Thus, during a profound and tranquil sleep, undisturbed by any dream, man ceases to feel. In short, notwithstanding the continued motion that agitates his frame, man does not appear to feel, when this motion acts in a convenient order; he does not perceive a state of health, but he discovers a state of grief or sickness; because, in the first, his brain does not receive too lively an impulse, whilst in the others, his nerves are contracted, shocked, and agitated, with violent, with disorderly motion: these communicating with his brain, give notice that some cause acts strongly upon them—impels them in a manner that bears no analogy with their natural habit: this constitutes, in him, that peculiar mode of existing which he calls grief.
On the other hand, it sometimes happens that exterior objects produce very considerable changes on his body, without his perceiving them at the moment. Often, in the heat of battle, the soldier perceives not that he is dangerously wounded, because, at the time, the rapidity, the multiplicity of impetuous motion that assails his brain, does not permit him to distinguish the particular change a part of his body has undergone by the wound. In short, when a great number of causes are simultaneously acting on him with too much vivacity, he sinks under their accumulated pressure,—he swoons—he loses his senses—he is deprived of feeling.
In general, feeling only obtains, when the brain can distinguish distinctly, the impressions made on the organs with which it has communication; it is the distinct shock, the decided modification man undergoes, that constitutes conscience. Doctor Clarke, says to this effect: "Conscience is the act of reflecting, by means of which I know that I think, and that my thoughts, or my actions belong to me, and not to another." From this it will appear, that feeling is a mode of being, a marked change, produced on our brain, occasioned by the impulse communicated to our organs, whether by interior or exterior agents, by which it is modified either in a durable or transient manner: it is not always requisite that man's organs should be moved by an exterior object, to enable him to feel that he should be conscious of the changes effected in him: he can feel them within himself by means of an interior impulse; his brain is then modified, or rather he renews within himself the anterior modifications. We are not to be astonished that the brain should be necessarily warned of the shocks, of the impediments, of the changes that may happen to so complicated a machine as the human body, in which, notwithstanding all the parts are contiguous to the brain, and concentrate themselves in this brain, and are by their essence in a continual state of action and re-action.
When a man experiences the pains of the gout, he is conscious of them; in other words, he feels interiorly, that it has produced very marked, very distinct changes in him, without his perceiving, that he has received an impulse from any exterior cause; nevertheless, if he will recur to the true source of these changes, he will find that they have been wholly produced by exterior agents: they have been the consequence, either of his temperament; of the organization received from his parents; of the aliments with which his frame has been nourished; besides a thousand trivial, inappreciable causes, which congregating themselves by degrees produce in him the gouty humour; the effect of which is to make him feel in an acute and very lively manner. The pain of the gout engenders in his brain an idea, so modifies it that it acquires the faculty of representing to itself, of reiterating as it were, this pain when even he shall be no longer tormented with the gout: his brain, by a series of motion interiorly excited, is again placed in a state analogous to that in which it was when he really experienced this pain: but if he had never felt it, he would never have been in a capacity to form to himself any just idea of its excruciating torments.
The visible organs of man's body, by the intervention of which his brain is modified, take the name of senses. The various modifications which his brain receives by the aid of these senses, assumes a variety of names. Sensation, perception, and idea, are terms that designate nothing more than the changes produced in this interior organ, in consequence of impressions made on the exterior organs by bodies acting on them: these changes considered by themselves, are called sensations; they adopt the term perception when the brain is warned of their presence; ideas is that state of them in which the brain is able to ascribe them to the objects by which they have been produced.
Every sensation, then, is nothing more than the shock given to the organs, every perception is this shock propagated to the brain; every idea is the image of the object to which the sensation and the perception is to be ascribed. From whence it will be seen, that if the senses be not moved, there can neither be sensations, perceptions, nor ideas: this will be proved to those, who can yet permit themselves to doubt so demonstrable and striking a truth.
It is the extreme mobility of which man is capable, owing to his peculiar organization, that distinguishes him from other beings that are called insensible or inanimate; the different degrees of this mobility, of which the individuals of his species are susceptible, discriminate them from each other; make that incredible variety, that infinity of difference which is to be found, as well in their corporeal faculties, as in those which are mental or intellectual. From this mobility, more or less remarkable in each human being, results wit, sensibility, imagination, taste, &c.: for the present, however, let us follow the operation of the senses; let us examine in what manner they are acted upon, and are modified by exterior objects:—we will afterwards scrutinize the re-action of the interior organ or brain.
The eyes are very delicate, very movable organs, by means of which the sensation of light or colour is experienced: these give to the brain a distinct perception, in consequence of which, man forms an idea, generated by the action of luminous or coloured bodies: as soon as the eyelids are opened, the retina is affected in a peculiar manner; the fluid, the fibres, the nerves, of which they are composed, are excited by shocks which they communicate to the brain; to which they delineate the images of the bodies from which they have received the impulse; by this means, an idea is acquired of the colour, the size, the form, the distance of these bodies: it is thus that may be explained the mechanism of sight.
The mobility and the elasticity of which the skin is rendered susceptible, by the fibres and nerves which form its texture, accounts for the rapidity with which this envelope to the human body is affected when applied to any other body; by their agency, the brain has notice of its presence, of its extent, of its roughness, of its smoothness, of its surface, of its pressure of its ponderosity, &c. Qualities from which the brain derives distinct perceptions, which breed in it a diversity of ideas; it is this that constitutes the touch or feeling.
The delicacy of the membrane by which the interior of the nostrils is covered, renders them easily susceptible of irritation, even by the invisible and impalpable corpuscles that emanate from odorous bodies: by these means sensations are excited, the brain has perceptions, and generates ideas: it is this that forms the sense of smelling.
The mouth, filled with nervous, sensible, movable, irritable glands, saturated with juices suitable to the dissolution of saline substances, is affected in a very lively manner by the aliments which pass through it for the nourishment of the body; these glands transmit to the brain the impressions received: perceptions are of consequence; ideas follow: it is from this mechanism that results taste.
The ear, whose conformation fits it to receive the various impulses of air, diversely modified, communicates to the brain the shocks or sensations; these breed the perception of sound, and generate the idea of sonorous bodies: it is this that constitutes hearing.
Such are the only means by which man receives sensations, perceptions, and ideas. These successive modifications of his brain are effects produced by objects that give impulse to his senses; they become themselves causes, producing in his soul new modifications, which are denominated thought, reflection, memory, imagination, judgment, will, action; the basis, however, of all these is sensation.
To form a precise notion of thought, it will be requisite to examine, step by step, what passes in man during the presence of any object whatever. Suppose for a moment this object to be a peach: this fruit makes, at the first view, two different impressions on his eyes; that is to say, it produces two modifications, which are transmitted to the brain, which on this occasion experiences two new perceptions, or has two new ideas or modes of existence, designated by the terms colour and rotundity; in consequence, he has an idea of a body possessing roundness and colour: if he places his hand on this fruit, the organ of feeling having been set in action, his hand experiences three new impressions, which are called softness, coolness, weight, from whence result three new perceptions in the brain, he has consequently three new ideas: if he approximates this peach to his nose, the organ of smelling receives an impulse, which, communicated to the brain, a new perception arises, by which he acquires a new idea, called odour: if he carries this fruit to his mouth, the organ of taste becomes affected in a very lively manner: this impulse communicated to the brain, is followed by a perception that generates in him the idea of flavour. In re-uniting all these impressions, or these various modifications of his organs, which it have been consequently transmitted to his brain; that is to say, in combining the different sensations, perceptions, and ideas, that result from the impulse he has received, he has an idea of a whole, which he designates by the name of a peach, with which he can then occupy his thoughts.
From this it is sufficiently proved that thought has a commencement, a duration, an end; or rather a generation, a succession, a dissolution, like all the other modifications of matter; like them, thought is excited, is determined, is increased, is divided, is compounded, is simplified, &c. If, therefore, the soul, or the principle that thinks, be indivisible; how does it happen, that this soul has the faculty of memory, or of forgetfulness; is capacitated to think successively, to divide, to abstract, to combine, to extend its ideas, to retain them, or to lose them? How can it cease to think? If forms appear divisible in matter, it is only in considering them by abstraction, after the method, of geometricians; but this divisibility of form exists not in Nature, in which there is neither a point, an atom, nor form perfectly regular; it must therefore be concluded, that the forms of matter are not less indivisible than thought.
What has been said is sufficient to show the generation of sensations, of perceptions, of ideas, with their association, or connection in the brain: it will be seen that these various modifications are nothing more than the consequence of successive impulses, which the exterior organs transmit to the interior organ, which enjoys the faculty of thought, that is to say, to feel in itself the different modifications it has received, or to perceive the various ideas which it has generated; to combine them, to separate them, to extend them, to abridge them, to compare them, to renew them, &c. From whence it will be seen, that thought is nothing more than the perception of certain modifications, which the brain either gives to itself, or has received from exterior objects.
