Old-school political science theory, heavily influenced by the social movements and political organizations of the 1960s and 1970s, the time in which this was being written. The principal kind of organization being studied is a formal, voluntary association, and the analysis generally assumes a pluralistic system analogous to the United States. The central argument is that organizations and their leaders offer different kinds of incentives to their members in order to overcome the collective action / free rider problem and to maintain and enhance the organization, which I think is a useful and appropriate point to consider when assessing an organization and its purposes. The author identifies the principle types of incentives as material, solidary (specific or collective), and the “purposive” category, which is further subdivided into goal-oriented, ideological, or redemptive groups. There’s discussion throughout of how these incentives shape organizational structure, leadership, and so forth.
There are some interesting insights and asides, but I wasn’t fully convinced of the generalizability of the theory’s application. I think the question of organizational formation was not fully developed — the argument that these are often formed in response to perceived threats is interesting, but otherwise there’s a bit of hand-waving about cycles or waves that didn’t seem especially strongly-grounded. One chapter suggests that varying economic resources, social status, and psychological time horizons produce the degree to which individuals value particular incentives offered by organizations, although this is described in rather unfortunate “high status” / “low status” language. I didn’t find the explanation for why organizations such as materially-oriented machine political parties get supplanted by more ideological / purposive organizations very clear or compelling. There is a fair amount of discussion of labor union politics, which I’m not very well-read in. The use of violence or coercion as an organizational strategy is touched on, but not really addressed at length; the chapters on competition (with peer organizations pursuing similar objectives) and oppositional protest and bargaining are interesting, though I imagine there is also a lot of game theory out there along these lines that I haven’t read.
Interesting on the whole but maybe not readily applicable in current form.
