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