Abstract
A fresh, constructive inquiry into the metaphysics of knowledge and the principles of order by which the various disciplines are related and integrated. As the basis of this inquiry, the author provides a defense of metaphysical realism and intentional logic, in opposition to the reductive tendencies which he finds exemplified in naturalism, idealism, nominalism, and the "postulational" ontologies of such thinkers as Whitehead. The aim of the work is a natural classification of knowledge, based on kinds of evidence and subject matter, and on an understanding of the manner in which each discipline presupposes the others.--J.
