ABSTRACT
The clarion call just noted is for scientific emphasis upon the wholes rather than the parts. This emphasis in Gestalt Theory was made manifest as a concern for fields and field theory, and, most broadly the commonality of principles governing order in living and behavioral things. The action is that of local contact, between one charge and the field of another charge or one pole and the field of another pole. W. Kohler argued for neural brain fields in accounts of perception. K. Koffka claimed that human acts were to be understood in terms of a behavioral field. The Gestalt perspective on the scientific challenges posed by perception was guided by what Kohler would aptly come to call the Invariance Postulate of Evolution—the primacy and continuity of the laws of dynamics. The postulate is that all biological facts and events are understandable in terms of the laws and principles responsible for the facts and events in the inanimate world.
