The article deals with American Personalist Thomist, W. N. Clarke, and his theory of the foundation of metaphysics in interpersonal dialogue. Classical Thomist metaphysics is based on the philosophy of nature. Clarke does not reject this approach, but he prefers his theory as better and more useful.
