In On Human Action and Practical Wisdom, Yang Guorong offers a description of his concrete metaphysics. This system seeks to overcome traditional metaphysical problems by providing a concrete basis - which serves as both the starting point and the final determining factor - for metaphysics. Yang gives a discussion of wisdom and practical action that begins in our everyday activities and social relationships, is extended to form universal principles, and finally refers back to actual situations for determining appropriateness.

Based on his unification of ontology, epistemology and axiology, Yang thus attempts to overcome the one-sided understanding of action in modern Western philosophy, targeting in particular the excessively linguistic, logical, and abstract focus found in the American analytic tradition.
