Immanuel Kant
Kant developed his moral philosophy in three works: "Groundwork of the Metaphysic of Morals" (1785), "Critique of Practical Reason" (1788), and "Metaphysics of Morals" (1797).
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.
