2. _Discipleship of Kant_ (1790–1794). Fichte returned from Zurich to Leipsic, and in the capacity of tutor in philosophy he assisted a young man in the reading of Kant’s _Critique_. He was at once converted heart and soul to the Kantian doctrine. In 1791 he called on Kant at Königsberg and submitted to Kant his _Critique of Revelation_. The next year he published this work, and by some fortunate accident his name as author was omitted from the title-page. The work was attributed to Kant, and was widely read as a masterpiece by Kant. Kant had to correct the mistake, which, however, made the real author, Fichte, famous. So he returned to Zurich in 1793 to marry Fräulein Rahn, who was herself now in comfortable circumstances. 3. _His Life at Jena_ (1794–1799). The year 1794 was another milestone in the biography of Fichte. In this year he was called to Jena, then the principal university of Germany, to succeed Rheinhold. In this year he published his philosophy in his best known work, the _Wissenschaftslehre_. He remained at Jena only five years. At first his popularity exceeded that of the popular Rheinhold, but he soon filled his life with controversies. He quarreled with the students and the clergy, and in 1799 the so-called “Atheistic Controversy” arose, in which charges were brought against his teaching as atheism. Brooking no criticism either of his teaching or of his official position, he defied the authorities of the university and was dismissed. 4. _His Life at Berlin_ (1799–1814). In 1799 Fichte went to Berlin to live. At first he had no academic affiliations, but he found a large and sympathetic public, to whom he lectured. He was warmly received by the circle of Romanticists,――the Schlegels, Tieck, and Schleiermacher. His philosophical system got little development; but the influence of Spinoza appeared in his teaching. He lectured upon the ethical and religious aspects of his philosophy, and upon political and social subjects. In 1808 he delivered his famous _Addresses to the German People_. In 1810 the University of Berlin was founded and he was called to the chair of philosophy, but he was connected with the university only two years. For in 1812 came the call to arms, and Fichte was with difficulty dissuaded from enlisting. He remained in Berlin and preached to the soldiers in camp. His wife volunteered as hospital nurse and contracted a fever, from which she recovered. Fichte, however, who nursed her through her sickness, died of the disease in 1814.
