Immanuel Kant
Immanuel Kant (22 April 1724 – 12 February 1804) was a German philosopher born in Königsberg, East Prussia. Kant studied philosophy at the University of Königsberg, and later became a professor of philosophy. He called his system "transcendental idealism". Kant's writing about epistemology, metaphysics, ethics, and aesthetics have made him one of the most influential figures in the history of philosophy.
