Pressure Group Theory: Its Methodological Range

Abstract

An outstanding advance in one field of human endeavor will often inspire workers in others to try to transfer its conceptions or techniques into their own less successful fields, for obvious reasons. And so political theorists who have long been discontented with the state of politics when compared with that of certain other sciences have, in consequence, sought to advance their field by adopting the ideas or techniques of their scientific contemporaries. The impressive application of physics will probably increase both political tension and the political scientists' interest in methodology.The last hundred years of political science have seen attempts at the introduction of various exotica, Darwinism, Economism, Freudianism, even Statisticism; but what I shall here discuss is the centuries-old attempt to appropriate the success of dynamics or mechanics to politics, an attempt which found its first great exponent in Hobbes but which has been carried on in this century by men like Bentley and Catlin. The success of dynamics, such men seem to have thought, is evidently the result of its method, which they took to be the reduction of phenomena to the primary qualities of matter and motion. We who are interested in politics, accordingly, will do well to copy the method of the successful scientists and reduce all political phenomena to similar primary entities. Just as Newtonian physicists speak of material bodies or particles, and the forces they exert upon each other, so we must confine ourselves to the description of the motions of atomic political bodies and the forces they exert upon each other. Thus we need only speak with Hobbes of men and their desires, or with Catlin of political men and their wills, or with Bentley of groups and their pressures, in order to succeed. We know that, in the early chapters of Leviathan, Hobbes announced this as his programme; but it is doubtful whether, as he moved from methodology to political theory, he did as he said he would do and whether he had not worked out his political theory before he “deduced” it from his primary entities of matter and motion. In what follows I shall try to show a similar history in the work of A. F. Bentley and D. B. Truman. I shall try to show that Bentley announced a methodological programme and that Truman's “development” of it has been quite external and could, in fact, have been undertaken without any reference to Bentley at all. I shall try to show, that is, that Bentley's contribution to political science has been of a psychological rather than a logical kind, and that the references made to him by contemporary pressure group theorists are similar to those which a Russian physicist might make to dialectical materialism.
