Johann Gottlieb Fichte

Johann Gottlieb Fichte was born on 19 May 1762 in Rammenau, Saxony, into a poor family of ribbon-weavers. His exceptional talent attracted the attention of a local nobleman, who enabled him to study at the Pforta school and later at the universities of Jena and Leipzig. Initially influenced by Spinoza and then deeply by Kant’s philosophy, he first gained fame with the anonymous publication of Attempt at a Critique of All Revelation (1792), which many readers attributed to Kant himself.

In 1794 Fichte was appointed professor at the University of Jena, where he developed his philosophical system, the Wissenschaftslehre. He took the absolute “I” as the foundational principle: the I posits itself and, by positing the “not-I,” constitutes the world. This approach discarded the Kantian dualism of the thing-in-itself and stressed the free, moral activity of the subject. Major works of this period include the Foundation of the Entire Wissenschaftslehre, the System of Ethics, and the Foundation of Natural Right.

After accusations of atheism forced him to leave Jena, Fichte settled in Berlin and, during the Napoleonic occupation, delivered the Addresses to the German Nation (1807–1808), which played a significant role in shaping German national consciousness. In his final years he held a professorship at the University of Berlin and died on 27 January 1814 of illness. Fichte’s philosophy, with its emphasis on freedom, moral action, and the autonomy of the subject, remains a pivotal moment in the history of German Idealism.
