The political theory implicit in social casework theory can be defined, for purposes of this discussion, as the theory of the relationship between man and society on which professional social casework is consciously predicated, or that theory of the relationship which is logically implied by social casework practice. This theory is not often consciously articulated and we must look for it, therefore, in those presuppositions underlying casework theory which are frequently accepted uncritically, if not wholly unconsciously. This practice obviously cannot be carried on without basic (although perhaps not entirely conscious) presuppositions about what man is like and consequently about what society can or ought to do for him.The presuppositions underlying social casework theory, although important in any context, have acquired a new significance to the extent that social casework has increasingly become a government function. During the past twenty years literally millions of people in the United States have been brought into a new relationship with officials of their local, state, and national governments—namely, the relationship of client and social caseworker.
