Immanuel Kant’s Critique of Pure Reason (1781) is one of the most important works in the history of philosophy, an investigation into the powers and limits of human reason. Kant argues that the mind actively structures experience through forms of intuition and categories of understanding, and that metaphysics must be reconceived in light of this “Copernican revolution” in thought.
