The tribute given to Saul Alinsky on his death in 1972 indicates the attention paid in our age to the problems of community organizing. Most citizen groups formed in response to such threats as urban renewal, danger to the environment, or mandatory busing face problems of factionalism, inefficiency, lack of money, and even conflicting loyalties of their members, unless they have the direction of someone like Alinsky, who earned his reputation as a professional organizer. The alternative is to found a group imbued with an ideology which can be characterized as radical (“as a kind of mental and moral discipline”) and an organization which consequently reflects this discipline. The existence of such political organizations, “specially designated and organized bands of men [who] might play a creative part in the political world,” of individuals motivated to join forces “with any man who might help them without regard to the older bonds of family and neighborhood” have a historical origin: they were the contribution of the religious wars in sixteenth-century Europe. The Calvinists were the ancestors of the Bolsheviks.
