A discipline, like an individual, may in some measure be known by the dilemmas it keeps, or more properly by the manner in which it keeps them.

A central conceptual controversy, probably inescapable for political scientists because of their disciplinary heritage, is that involved in perceiving uniformities in behavior, describing recurring patterns, identifying the determinants and yet reconciling this effort and its underlying premises about the roots of behavior with the liberal, democratic faith in man's individual capacity to determine his own ends, to think rationally and to reach individual and creative decisions. On this faith rests the political structure of rights, the machinery of the democratic electorate, the party system and the values of the constitutional democratic state whose political process we are concerned to describe and analyze. Cultural anthropologists, social psychologists of many disciplinary schools, hard-boiled “realists” in political science, have recently drawn back from determinist or whole-heartedly relativist positions. Some are concerned that political science, in a fresh enthusiasm for empirical research, may become so engrossed with uniformities and determinants that it will obscure or abandon the normative commitments of a democratic polity.
