(1724 - 1804)
Immanuel Kant was a German philosopher who stressed the essential difference between "das Ding an sich" (the thing in itself) and "das Ding fĆ¼r mich" (the thing for me). His critical philosophy examined the limits of human knowledge and reason. His Critique of Pure Reason revolutionized Western philosophy. He proposed that our experience of reality is shaped by the structures of our own minds.
