On this day, 263 years ago, May 19, 1762 (April 26, 1762 in the lunar calendar), the German philosopher Johann Fichte was born. Johann Fichte (1762-1814) German philosopher. On May 19, 1762, Fichte was born in Rameno, Saxony, Prussia. In 1780, he entered the Divinity School of the University of Jena and began his studies. In 1784, due to financial reasons, he completed his studies before receiving his degree, and then worked as a tutor in Zurich. In 1790, he met Johana, the niece of the famous German poet Klopstock, and was deeply attracted by her. The two later married. In the same year, he began to study Kant's works, which had a profound impact on his later philosophical thinking. In 1791, he went to Konigsberg to visit Kant. In order to let Kant understand him, he wrote a long religious article based on Kant's philosophy,"A Trial Comment on All Revelation", which studied the connection between Kant's critical philosophy and the field of theology. After reading it, Kant praised it greatly. He not only sponsored the publication of the article, but also recommended Fichte to teach at a university. For unknown reasons, this article was published anonymously, making people think it was Kant's own long-awaited critical work on religion. Kant later clarified the facts and publicly praised the work, an event that made Fichte famous in the philosophical world. In 1794, Fichte became a professor at the University of Jena, presiding over Kant's philosophical lectures and improving his philosophical system. Since then, he successively published "The Foundation of All Knowledge Science","The Foundation of Natural Law","The Moral System under the Principles of Knowledge Science", etc. In 1798, when he was the editor-in-chief of the Philosophical Journal, he received a submission of religious skepticism. Although Fichte did not agree with the author's views, he published the article because he insisted on freedom of publication. The article was later used by ulterior motives to attack Fichte as an atheist and force him to leave Jena and move to Berlin. In 1806, the Franco-Prussian War broke out, and Fichte took on the task of promoting patriotism. In 1807, he returned to Berlin occupied by the French army and delivered the famous "Speech to the German Nation" and advocated the establishment of the University of Berlin. In 1810, the University of Berlin was established, and Fichte served as the first president. When the Battle for the Defense of Berlin broke out in 1813, the city was crowded with wounded people, and the plague was prevalent. Fichte was infected with typhus and died in January 1814.
