Abstract

Psyche uses the resources of psychology and philosophy for their mutual benefit.  Jung provides the best vehicle for this purpose because he is a radical experientialist, not an empiricist.  The combination of his insights and those of Sartre and Whitehead implies that the human is a syncretic unity of mutually irreducible aspects.  While the human often acts through emphasis upon only some of his capacities, he sometimes acts as a unitary being as when he insists and thus brings values to the world.  It is through such unitary actions that we can know totality itself in its syncretic unity.  [Abstract from The Philosopher's Index]
