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.
Felix Adler (professor)
Adler developed an original philosophy with a foundation in those of Immanuel Kant and G.W.F. Hegel that developed and transformed these roots. He considered philosophy not just a guide of life but key to improving society and the human condition appropriate to a respect for essential human dignity. Rejecting Kant's metaphysics he embraced his stress on the intrinsic worth and dignity of the person. Combining a supreme moral principle similar to Kant's with his own detailed ideas of self-realization, he emphasized free development of the individual in relation to societal concerns and fellowship. He preceded John Dewey in a concern for the "problems of men" instead of philosophical technicalities. While his ideas shared some aspects of pragmatism he was better described as "an ethical idealist with great practical reforming zeal" he promoted an idealist version of moral perfectionism. He was however realistic and not sentimental acknowledging that man has done evil knowingly and deliberately.
