Neo-Kantianism
In late modern Continental philosophy, Neo-Kantianism () was a revival of the 18th-century philosophy of Immanuel Kant. More specifically, it was influenced by Arthur Schopenhauer's critique of the Kantian philosophy in his work "The World as Will and Representation" (1818), as well as by other post-Kantian philosophers such as Jakob Friedrich Fries and Johann Friedrich Herbart.
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.
