Today, the science of man's subjective experience is in its infancy. But if it gains momentum, its consequences may be even more far-reaching than those which emerged from the Copernican, Darwinian, and Freudian revolutions. The following propositions have accumulated an impressive amount of substantiating evidence: 1) The potentialities of the individual are far greater than we ordinarily imagine them to be and far greater than current models of man would lead us to think possible; 2) A far greater portion of significant human experience than we ordinarily feel or assume to be so is comprised of unconscious processes; 3) Included in these processes are self-expectations and images of ourselves, others, and the future, which tend to be self-fulfilling. The new science will take these features into account. By doing so, it may ennoble the image of the individual's possibilities, of the educational and socializing processes, and of the future. Since the image man has of the future is crucial in determining what he does with it, such a science will be more useful than the older, mechanistic one in helping man survive. (JK)
