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"".
Goethean science
Immanuel Kant in Prussia undertook a major rescue operation to preserve the validity of knowledge derived via reason (science), as well as of knowledge going beyond the rational mind, that is of human liberty and of life beyond simply an expression of 'the chance whirlings of unproductive particles' (Coleridge). Kant's writings had an immediate and major impact on Western philosophy and triggered a philosophical movement known as German idealism (Fichte, Hegel, Schelling), which sought to overcome and transcend the chasm Kant had formalized between the sense-based and the super-sensible worlds, in his attempt to 'save the appearances' (Owen Barfield), that is, to preserve the validity of scientific or rational knowledge as well as that of faith.
