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).
An Attempt at a Critique of All Revelation
An Attempt at a Critique of All Revelation (; 1792) was the first published work by Johann Gottlieb Fichte. It was briefly mistaken by the public to be a fourth Critique by Immanuel Kant, and thereby gained Fichte much philosophical fame.
