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"".
Yirmiyahu Yovel
Yovel's first book, based on his PhD dissertation, was "Kant and the Renewal of Metaphysics" (1974, in Hebrew.) While Kant had been often held to have destroyed metaphysics, Yovel's book argues that Kant's actual program was to renew it, by replacing the old dogmatic metaphysics with a new critical one. Metaphysical questions are deeply significant even when they exceed the range of legitimate answers. To either repress the questions or to pretend answering them is equally irrational. Reason in Kant has a metaphysical interest and a critical interest that are equally indispensable, yet contradict each other in the absence of a critique. The critical turn resolves this antinomy in two stages. First, it establishes a system of synthetic a-priori categories and principles that functions as a valid metaphysics of the immanent (empirical) domain; and, secondly, in the Dialectic, it re-orients the metaphysical drive from its search of empty, illusory objects back into the empirical world, and makes us realize our fundamental finitude, as well as the endlessly open horizons within this world which we can explore.
