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).
Wissenschaft
Before Immanuel Kant published his "Critique of Judgment" in 1790, the ""schöne Wissenshaft"" (roughly, "fine sciences") were highly regarded. The ""schöne Wissenshaft"" included poetry, rhetoric, and other subjects that were meant to promote an understanding of truth, beauty, and goodness. Kant argued persuasively that aesthetic judgments were not an area of systematic knowledge, and therefore were outside the realm of Wissenschaft.
