“I openly confess, the suggestion of David Hume was the very thing, which many years ago first awakened me from my dogmatic slumber, and gave my investigations in the field of speculative philosophy quite a new direction.”
– Immanuel Kant, in the Introduction to his “Prolegomena to Any Future Metaphysics” (1783)
Immanuel Kant may have been the most influential philosopher since antiquity. He was active in virtually every area of philosophy, with writings on many of its subfields. These included epistemology, metaphysics, aesthetics, and ethics. He was probably the most influential of all of the German philosophers, and helped to establish a tradition of writing philosophical works in the German language.
