German idealism
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 Schopenhauer's criticism 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.
Mou Zongsan
Mou's philosophy develops as a critique and transformation of Kant's critical philosophy. Mou believes in the compatibility of Chinese thought and Kantian philosophy because both are backed by the Way, where the Way is essentially truth and different philosophies manifest different aspects it. Mou's analysis of Kant centers on Kant's "Critique of Pure Reason". One of Mou's major criticisms of Kant involves Kant's regard for free will as theoretical. Herein lies one of Mou's fundamental beliefs, that morality and the moral life are, contrary to what Kant posits, really real. This presumption stems from Mou's belief in the metaphysical necessity of the capability of improving one's moral praxis, and thus Mou develops a moral metaphysics within the tenet of subjectivism. While Kant believes that intellectual intuition is only possible for God, Mou ascribes human beings equal capability of this intuition, which Mou finds superior to Heidegger’s fundamental ontology. Mou rejects Heidegger because according to Kant, true metaphysics is transcendent. Mou further departs from Kant’s philosophy, eventually transforming it into what is commonly referred to as New Confucianism or Mind Confucianism.
