One of the major figures of the European Enlightenment, Immanuel Kant eradicated the last traces of the medieval worldview from modern thinking, advocated the autonomy of human reason over divine intervention and paved the way for much of the philosophy of the nineteenth and twentieth centuries. The writings reprinted here address the impact of this important philosopher. Two of the texts by Cassirer and Paton specifically address the monumental text Critique of Pure Reason in which the foundations of Kant's theory of knowledge are laid.
