Immanuel Kant
Kant published a second edition of the "Critique of Pure Reason" ("Kritik der reinen Vernunft") in 1787, heavily revising the first parts of the book. Most of his subsequent work focused on other areas of philosophy. He continued to develop his moral philosophy, notably in 1788's "Critique of Practical Reason" (known as the second "Critique") and 1797's "Metaphysics of Morals". The 1790 "Critique of Judgment" (the third "Critique") applied the Kantian system to aesthetics and teleology. It was in this critique where Kant wrote one of his most popular statements, ""it is absurd to hope that another Newton will arise in the future who will make comprehensible to us the production of a blade of grass according to natural laws"".
Hermann Kant
In his first novel, "The Aula" (1965), Kant described his own experiences at the "Workers and Peasants Faculty." In the book, the closure of the faculty is an occasion for a graduation, for which the main character is to deliver a speech, which determines the fate of their fellow students and thus a part of their own lives in the early days of East Germany. "Kant's most famous and best novel" made him famous overnight in both the East and the West, while the book also being considered controversial in both German states. In East Germany most viewed the book as a "partisan commitment" of Kantian protagonists devoted to the "socialist movement", Marcel Reich-Ranicki remarked that Kant was too timid to write about the real conditions that existed in East Germany.
