The Critique of Pure Reason by Immanuel Kant, first published in 1781, second edition 1787, is one of the most influential works in the history of philosophy. Also referred to as Kant's "first critique," it was followed in 1788 by the Critique of Practical Reason and in 1790 by the Critique of Judgment. In the preface to the first edition Kant explains what he means by a critique of pure reason: "I do not mean by this a critique of books and systems, but of the faculty of reason in general, in respect of all knowledge after which it may strive independently of all experience."
