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"".
Jean Genet
By 1949, Genet had completed five novels, three plays, and numerous poems, many controversial for their explicit and often deliberately provocative portrayal of homosexuality and criminality. Sartre wrote a long analysis of Genet's existential development (from vagrant to writer), entitled "Saint Genet" (1952), which was anonymously published as the first volume of Genet's complete works. Genet was strongly affected by Sartre's analysis and did not write for the next five years.
