Pennock and Chapman say that the theorist's job is to speculate and to interpret the facts as he sees them. It is also the theorist's job to suggest hypotheses for testing: to point to lines of inquiry that should be pursued. One cannot read the essays in this volume, without having his eyes opened—or opened wider—both to the paucity of information about the political features of voluntary associations and to the wide variety of aspects from which the subject needs to be approached. The kinds of questions that need to be examined can be grouped in categories. The first focuses on the individual: What kinds of memberships does he have? Even more, what is the effect upon him of membership in each kind of association? The second examines internal composition and workings of organizations. The third focuses on the state as a whole and the effect of organized groups upon it, the political processes of the associational structure of the society, and modes of behavior of these associations. Organized groups play an intermediate role in the polity. At the same time, the state, and those charged at any particular time with the performance of its functions, must look primarily to new associations within it to secure compliance with its law and for guidance in shaping those laws.
