"System theory is basically concerned with problems of relationships, of structure, and of interdependence rather than with the constant attributes of objects. In general approach it resembles field theory except that its dynamics deal with temporal as well as spatial patterns. Older formulations of system constructs dealt with the closed systems of the physical sciences, in which relatively self-contained structures could be treated successfully as if they were independent of external forces. But living systems, whether biological organisms or social organizations, are acutely dependent on their external environment and so must be conceived of as open systems"

“Racial prejudice is thus a generalized set of stereotypes of a high degree of consistency which includes emotional responses to race names, a belief in typical characteristics associated with race names, and an evaluation of such traits.”

“Value-expressive attitudes not only give clarity to the self-image but also mold the self-image closer to the heart’s desire.”

The specific ways in which he does this may vary from situation to situation, but they contribute to a supportive personal relationship between himself and his work group members”

“The homeostatic principle does not apply literally to the functioning of all complex living systems, in that in counteracting entropy they move toward growth and expansion.”
