My task is almost completed. My mind is stored with an immense treasure, which I have gathered, bee-like, in your world, and with which I must now return to the great and fair hive whence I came. The other side of my task also is drawing to a close. I have almost finished this my second message to my own remote ancestors, the First Men.

Very soon I shall be free to leave your world of sorrow and vain hope, of horror and of promise unfulfilled. Presently I shall return to an age long after the destruction of your planet, and not long before the more tragic destruction of my own more delectable world. Only with difficulty and danger can the explorer, after close work in the past, revert once more to his own world. With difficulty and reluctance also, I shall now begin to put off your mental pattern from my mind, as one may put off a mask. As the grown man who has been long with children, living in their games, grieving with them in their childish sorrows, is tom with regret when at last he must leave them, and half-persuades himself that their nature and their ways are better than his own, so I now with reluctance leave your world, with its childish, its so easily to be avoided yet utterly inescapable, its farcical and yet most tragic, disaster. But even as, when at last the grown man is once more at grips with the world of men, his childishness falls from him, so, when I earnestly revert in imagination to my own world, my assumed primitiveness falls from me.

It is time to recall myself to myself. I have been dwelling in your little world, not as one of you, but in order that I might bring to the racial mind of the Last Men matter for delighting cognizance; in order, also, that your world may find its crown of glory, not indeed in the way that was hoped, but in being exquisitely savoured, life by life, event by event, in the racial mind of the Last Men.

I recall myself to myself. The great world to which I am native has long ago outgrown the myths, the toys, the bogies of your infant world. There, one lives without the fear of death and pain, though there one dies and suffers. There, one knows no lust to triumph over other men, no fear of being enslaved. There one loves without craving to possess, worships without thought of salvation, contemplates without pride of spirit. There one is free as none in your world is free, yet obedient as none of you is obedient.

I recall myself to myself. The most lovely community of which I am a member, the most excellently fulfilled Spirit of Man, within which my mind is organic, must very soon be destroyed. The madness of the Sun is already hideously at work upon my world. There lies before my contemporaries an age of incalculable horror and disintegration. From that horror we must not escape by means of the racial suicide which alone could save us; for our two supreme acts of piety are not yet accomplished. We have not yet succeeded in impregnating the remote regions of this galaxy with the seed of a new mankind. We have not yet completed our devoted survey of the past. Therefore we may not yet put an end to ourselves. We must be loyal to the past and to the future.

I recall myself to myself. Presently I shall wake in my Arctic and subterranean garden. Once more I shall see with precision and with full colour through my own eyes, not through the obscuring organs of the First Men. I shall recognize the familiar forms of Neptunian leaves and flowers, swaying in the subterranean breeze. I shall feel the large easefulness of my own body. I shall yawn and stretch and rise. I shall swim luxuriously in my pool. I shall enter my apartment and ring for food. Then, before I see any of my colleagues, I shall begin to review my exploration; I shall record it, and critically edit it. For now at last I shall have recovered full Neptunian mentality. I shall see with new insight not only your world but my own self as I was during my long immersion in your world. Probably I shall smile at my recent earth-infected thoughts and feelings. I shall smile when I remember this book, this strange hybrid sprung from the intercourse of a purely Terrestrial mind and a Neptunian mind, earth-infected. I shall know that, even when I most strained the understanding of my poor collaborator, I was not really giving him the full wisdom of the Last Men, but something far less profound, something that was already earth-dimmed, already three-parts Terrestrial even at its source in my own mind.

With a great thankfulness I shall recognize my own complete reversion to lucidity. With a new awe and zest I shall lay myself open once more to the inflooding richness and subtlety of my well-loved world.

After many weeks of labour I shall have completed my report, and then I shall leave my apartment and meet many of my colleagues, to exchange findings with them.

But, since in the Catacombs telepathic intercourse may not occur, we shall soon travel south to live together for a while in a great crystal pylon where we may pursue our collaboration telepathically. And when we have made of our combined findings a single, living, apprehension of your species, we shall broadcast our great treasure telepathically over the whole world; so that all the million million minds of our fellows may be enriched by it, so that when the time comes for the next awakening of the single mind of the race, that great spirit also, which is not other than each of us fully awakened, may avail itself of our findings, for its meditation and ecstasy.

When all this is done I shall call up telepathically the ever dear companion of my holidays, with whom, before my last exploration, I played and slept, where the broken mountain lies spread out into the sea. There once more we shall meet and play, watching the populations of the rock pools, and the risings and settings of the Mad Star. There once more we shall wander over the turfy hillocks and swim, seal-like, in the bay, and make for ourselves nests in the long grass, where we may lie together in the night. There perhaps I shall tell her how, in another world, seemingly in another universe, I myself, striving in the numb, the half-human flesh of Paul, lay with the half-human Katherine. There we shall contemplate the strange beauties of the past and of the dread future. There we shall savour lingeringly the present.

When our holiday is over I shall return with her to her place of work, where they prepare for the spreading of the seed. And when she has shown me how the task is progressing, I shall go wandering about the world for a very long time, absorbing its intricate beauty, watching its many and diverse operations, having intercourse with the great population of my intimate friends, playing my part in the life of my marriage group, visiting the Land of the Young, voyaging in ether-ships among the planets, wandering alone in the wild places of the home planet, idling or meditating in my garden or working among my fruit trees, or watching the most distant universes from some great observatory, or studying with the help of astronomers the slow but fatal progress of the sun’s disease.

It may be that before it is time for me to go once more into the past, there will occur again a supreme awakening of the racial mind. It may be that after the unique day of the awakening I shall for a long time move about the world entranced like my fellows, rapt in the ineffable experiences of the single Spirit of Man, contemplating perhaps at last the supernal entities which it is man’s chief glory to strive to worship. Sooner or later, however, I shall return once more to my work in the past, either to the First Men or to some other primitive species. I shall bring back with me more treasure of living history, and deliver it into the world of the Last Men. And again I shall play, and again I shall participate in the rich life of my world, and again I shall return to the past. And so on for I know not how many times.

But each time, when I leave the present for the past, there will have been a change in my world, a slight deterioration, sometimes perhaps imperceptible. The climate will have grown hotter and more unwholesome. The inescapable rays of the mad sun will have done more harm to eyes and brains. Society will perhaps no longer be perfect, rational conduct no longer invariable, telepathy perhaps already difficult; and very probably the racial mentality will have already become impossible. But also the exploration of the past will be advancing toward completion, though with increasing difficulty; and the dissemination of the seed of life will be at last begun.

The Last Men can look forward without dismay to the inevitable deterioration of all that they cherish most, to the death of their fair community, and to the extinction of the human spirit. We have only one desire, namely that our two tasks may be accomplished; and that happily they may be accomplished before our deterioration is so far advanced as to make us incapable of choosing to put an end to ourselves when at last we are free to do so. For the thought is somewhat repugnant to us that we should slowly sink into barbarism, into the sub-human, into blind and whimpering agony, that the last of Man should be a whine.

This may well happen, but even by such a prospect we are not seriously dismayed. If it does occur, it will doubtless seem intolerable to our degraded spirits. But today, we are fully possessed of ourselves. Even as individuals, even apart from the exaltation of racial mentality, we can accept with resignation, nay with a surprising fervour of appreciation, even the moral downfall of our world. For we have gone far. We have drunk deeply of beauty. And to the spirit that has drunk deeply of the grave beauty of the cosmos, even the ultimate horror is acceptable.
