Abstract

Some 2300 years ago, Hellenic Philosophy had already produced some rather sophisticated theories of human psychological functioning as well as most of the broad theoretical controversies which characterize the contemporary psychological stage. Democritus, for example, had put forth a theory of thinking and action which emphasized the physiological components of the person and looked to immediate environmental antecedents as explanations for what we did. Plato, by contrast, insisted upon the formal rule-governed characteristics of human thinking as basic to intellect and denied the possibility that these could be acquired piecemeal through experience with environmental events. Nor would he accept the relevance of physiological descriptions for answering psychological questions. The following centuries have witnessed both the intensification of these controversies and their proliferation into new scientific and societal spheres, as intellectual fashions have favored now one and then another theoretic orientation. A resolution to many such controversies was proposed by Aristotle in the course of formulating his developmental and teleological doctrine of Man, and the logic of this mode of resolution still has great relevance today for the evaluation of psychological theories. In Aristotle's account, a new approach to the concept of causality evolved, an approach that paid special attention to how the term "causes" should be applied to biological events. Moreover, this approach to causality was highly successful in integrating biological phenomena with an understanding of the nature of causes for psychological phenomena. The explication of this account demonstrated that "why" explanations and "how" explanations of action could and should be used concurrently and also demonstrated that many psychological controversies were based on pseudo-issues. This approach, and particularly its relevance to developmental psychology, will be outlined here. 2012 APA, all rights reserved)
