Who developed Kantian philosophy?
Immanuel Kant
Immanuel Kant (/kænt/;[15] German:[ʔɪˈmaːnu̯eːl ˈkant, -nu̯ɛl -];[16][17] 22 April 1724– 12 February 1804) was a German philosopher who is a central figure in modern philosophy.[18] 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.[19][20] 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.[21] 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.
Ernst Cassirer
Donald Phillip Verene, who published some of Cassirer's papers kept at Yale University, gave this overview of his ideas:
“Cassirer as a thinker became an embodiment of Kantian principles, but also of much more, of an overall movement of spirit stretching from the Renaissance to the Enlightenment, and on to Herder’s conception of history, Goethe’s poetry, Wilhelm von Humboldt’s study of the Kavi language, Schelling’s "Philosophie Der Mythologie," Hegel’s "Phenomenology of Spirit," and Vischer’s conception of the aesthetic symbol, among many others. Cassirer’s own position is born through a mastery of the whole development of this world of the humanistic understanding, which included the rise of the scientific world view — a mastery evident both in his historical works and in his systematic philosophy.”
