Abstract: To solve the tension between scientism and humanism in the 20th century, FENG Qi regards exploring the relationship between knowledge and wisdom as his task. Integrating Marxist philosophy, traditional Chinese philosophy and Western philosophy, FENGs epistemology in a broad sense interprets wisdom from a new perspective. FENG attempts to transcend the boundary between ignorance and knowledge. His theory of the transformation of knowledge into wisdom involves epistemology, ontology and metaphysics. By integrating ontology and ethics into his epistemology in a broad sense, FENG provides a unique solution to the binary relations between noumenon and phenomena and forms an innovative postMarxist theory of knowledge.
