General systems theory is the scientific exploration of "wholes" and "wholeness" which, not so long ago, were considered metaphysical notions transce… - Ervin László

The systems view of nature and man is clearly non- anthropocentric, but it is not non-humanistic for all that. It allows us to understand that man is one species of system in a complex and embracing hierarchy of nature, and at the same time it tells us that all systems have value and intrinsic worth. They are goal-oriented, self-maintaining, and self-creating expressions of nature's penchant for order and adjustment. The status of man is not lessened by admitting the amoeba as his kin, nor by recognizing that sociocultural systems are his supersystems. Seeing himself as a connecting link in a complex natural hierarchy cancels man's anthropocentrism, but seeing the hierarchy itself as an expression of self-ordering and self-creating nature bolsters his self-esteem and encourages his humanism.

In the penultimate decade of the twentieth century science is sufficiently advanced to resolve the puzzles that stymied scientists in the last century and demonstrate, without metaphysical speculation, the consistency of evolution in all realms of experience. It is now possible to advance a general evolution theory based on unitary and mutually consistent concepts derived from the empirical sciences.

The notion of "system" has gained central importance in contemporary science, society and life. In many fields of endeavor, the necessity of a "systems approach" or "systems thinking" is emphasized, new professions called "systems engineering," "systems analysis" and the like have come into being, and there can be little doubt that this this concept marks a genuine, necessary, and consequential development in science and world-view.
