ABSTRACT
Modern naturalistic theories of man proceed from a more mature conception of matter than is found in the mechanistic theories—a conception enriched by all the sciences, and not formulated entirely in terms of physics. 1 Such a naturalistic approach relies on the method and criteria of science in its account of the mental as of all else in nature. Its essential core is the stress upon man as dynamic, participating in events and reacting with and to his environment. Mind is understood in terms of activities or events and their qualities.
