ABSTRACT
General system theory is intended to elaborate properties, principles and laws that are characteristic of “systems” in general, irrespective of their particular kind, the nature of their component elements, and the relations or “forces” between them. General system theory can be developed in various mathematical languages, in vernacular language, or can be computerized. In some way parallel to this is the stratification observed in the mental system which can be roughly circumscribed as the domains of: instincts, drives, emotions, the primeval “depth personality”; conscious perception and voluntary action; and the symbolic activities characteristic of man. The principle of differentiation is ubiquitous in biology, for example, the evolution and development of the nervous system, behavior, psychology and culture. The behavior of any organism in innumerable activities under natural circumstances goes far beyond reduction of tensions or gratification of needs. All such behavior is performed for its own sake, deriving gratification from the performance itself.
