Johann Gottlieb Fichte was a German philosopher who became a founding figure of the philosophical movement known as German idealism, which developed from the theoretical and ethical writings of Immanuel Kant. Recently, philosophers and scholars have begun to appreciate Fichte as an important philosopher in his own right due to his original insights into the nature of self-consciousness or self-awareness. Fichte was also the originator of thesis–antithesis–synthesis, an idea that is often erroneously attributed to Hegel. Like Descartes and Kant before him, Fichte was motivated by the problem of subjectivity and consciousness. Fichte also wrote works of political philosophy; he has a reputation as one of the fathers of German nationalism.
Johann Gustav Bernhard Droysen was a German historian. His history of Alexander the Great was the first work representing a new school of German historical thought that idealized power held by so-called "great" men.
Johann Eduard Hari is a British-Swiss writer and journalist who wrote for The Independent and The Huffington Post. In 2011, Hari was suspended from The Independent and later resigned, after admitting to plagiarism and fabrications dating back to 2001 and making malicious edits to the Wikipedia pages of journalists who had criticised his conduct. He has since written books on the topics of depression, the war on drugs, and the effect of technology on attention spans, which have attracted criticism for poorly evidenced claims, misrepresented sources, and bad citational practices.
