What is "neo-kantianism"

Neo-Kantianism \Ne`o-Kant"i*an*ism\, n. The philosophy of modern thinkers who follow Kant in his general theory of knowledge, esp. of a group of German philosophers including F. A. Lange, H. Cohen, Paul Natorp, and others.

Neo-Kantianism refers broadly to a revived type of philosophy along the lines of that laid down by Immanuel Kant in the 18th century, or more specifically 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. It has some more specific reference in later German philosophy.
