Immanuel Kant
Immanuel Kant (; ; 22 April 1724 – 12 February 1804) was a German philosopher who is a central figure in modern philosophy. In his doctrine of transcendental idealism, he argued that space, time and causation are mere sensibilities; "things-in-themselves" exist, but their nature is unknowable. In his view, the mind shapes and structures experience, with all human experience sharing certain structural features. He drew a parallel to the Copernican revolution in his proposition that worldly objects can be intuited "a priori" ("beforehand"), and that intuition is therefore independent from objective reality. Kant believed that reason is the source of morality, and that aesthetics arise from a faculty of disinterested judgment. Kant's views continue to have a major influence on contemporary philosophy, especially the fields of epistemology, ethics, political theory, and post-modern aesthetics.
History of philosophy in Poland
Another Polish proponent of Kantism was Józef Kalasanty Szaniawski (1764–1843), who had been a student of Kant's at Königsberg. But, having accepted the fundamental points of the critical theory of knowledge, he still hesitated between Kant's metaphysical agnosticism and the new metaphysics of Idealism. Thus this one man introduced to Poland both the antimetaphysical Kant and the post-Kantian metaphysics.
