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"".
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.
