Abstract
In the heyday of functionalist sociology and anthropology it was common to speak of the 'functional requisites' or basic functions of societies, one of which was what Parsons called pattern maintenance, a term which referred primarily to the reproduction of social practices through the socialization of children. Marxists speak of the base of social formations, and include in this the reproduction of capitalist work relations. A common thread in the two concepts is the thought that there are necessary conditions for the continuation of a given social form which are not 'external' but are integral to the social form itself. Academics and scientists arc in the business of mastering a tradition and passing it on, so one may ask an analogous question about the reproduction of academic or scientific perspectives: what is required for the continuation or reproduction of an academic or scientific perspective, and how does this 'requisite' exert a selective effect between perspectives in given environments?
