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).
Benedict Stattler
Shortly after Adam Weishaupt had founded the secret society of the Illuminati, Stattler attacked them in an anonymous work (Das Geheimniß der Bosheit des Stifters des Illuminatismus in Baiern). Kant's "Critique of Pure Reason" appeared in its first edition in 1781; in 1788 Stattler launched his "Anti-Kant", and parried the attack which his book provoked in the literary world of Germany.
