A pivotal piece of philosophical literature, "The Critique of Pure Reason" is quite likely Immanuel Kant's greatest work. Kant was a professor of philosophy in the German city of Konisberg during the late 1700s. It was during that time that he penned several works based on his philosophical beliefs of which the greatest is often considered to be this work. Considered by many as one of the most important works of philosophy ever written, "The Critique of Pure Reason" puts forth Kant belief that true knowledge comes from a combination of pure reason and experience. Presented here in this volume is the classic translation of J. M. D. Meiklejohn.
