Immanuel Kant
Kant published other important works on ethics, religion, law, aesthetics, astronomy, and history. These include the "Universal Natural History" (1755), the "Critique of Practical Reason" (1788), the "Metaphysics of Morals" (1797), and the "Critique of Judgment" (1790), which looks at aesthetics and teleology.
Johann Gottlieb Fichte
From Zurich, Fichte returned to Leipzig in May 1790. In the spring of 1791, he obtained a tutorship at Warsaw in the house of a Polish nobleman. The situation, however, quickly proved disagreeable and he was released. He then got a chance to see Kant at Königsberg. After a disappointing interview on July 4 of the same year, he shut himself in his lodgings and threw all his energies into the composition of an essay which would compel Kant's attention and interest. This essay, completed in five weeks, was the "Versuch einer Critik aller Offenbarung" ("Attempt at a Critique of All Revelation", 1792). In this book, according to Henrich, Fichte investigated the connections between divine revelation and Kant's critical philosophy. The first edition of the book was published without Kant's or Fichte's knowledge, moreover without Fichte's name or signed preface. It was thus mistakenly thought to be a new work by Kant himself.
