A vision of a future social order [must] be based on a concept of human nature. If, in fact, man is an indefinitely malleable, completely plastic being, with no innate structures of mind and no intrinsic needs of a cultural or social character, then he is a fit subject for the ‘shaping of behavior’ by the State authority, the corporate manager, the technocrat, or the central committee. Those with some confidence in the human species will hope that this is not so and will try to determine the intrinsic human characteristics that provide the framework for intellectual development, the growth of moral consciousness, cultural achievement, and participation in a free community … We must break away, sharply and radically, from much of modern social and behavioral science if we are to move towards a deeper understanding of these matters.
