Personality as a function of human design
(RESUME)

The distinctive charakteristics of human personality is a consciousness capable of reflection and able to create variants of itself by design. The author reviews the developing situation in personality theory as he now sees it, and outlines "design-functionalism in personality" in its development. It is an approach to the psychology of personality through a consideration of the implications for consciousness of the basic features of the design of man. The most distinctive features of human personality are: our inherent duality; the pervasiveness and generative power of conflict; our capasity to choose and to grow from our choices; and our power to create and to evolve by our own design through reflection upon the changes we bring about.
