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"".
Christian Garve
Of interest is his engagement with Immanuel Kant, which was initiated by a review of Kant's "Critique of Pure Reason" in the "Göttinger Gelehrten Anzeigen" ("Göttingen Learned Advertiser") which had been shortened by the Göttingen philosopher Johann Georg Heinrich Feder. Kant felt himself to have been misunderstood, and complained bitterly about the review in the Appendix to his Prolegomena to Any Future Metaphysics that Will Henceforth Come Forward as a Science. When the original, longer review was published by Garve in the "Allgemeine Deutsche Bibliothek" ("General German Library"), it still attracted Kant's censure. Kant consequently wrote his own "Anti-Garve". This program in time expanded into Kant's "Groundwork of the Metaphysics of Morals". The intellectual engagement between Kant and Garve extended up to Garve's death of cancer in 1798.
