Functionalism
FUNCTIONALISM is the analytical tendency within the social sciences—most notably, sociology and social anthropology—that exhibits a particular interest in the functions of social or cultural phenomena. In its most traditional form, functionalism has claimed that all items and activities in a system should be explained in reference to their objective consequences for the system as a whole. Thus the pivotal meaning of function is the objective consequence of an activity or phenomenon for the system of which it is a part. A secondary—but nonetheless significant—meaning of function in social science is similar to the use of the term in mathematics. When it is stated that x is a function of y, it is meant that x varies in direct proportion to variation in y. In social science this perspective on the concept of function has to do with interrelatedness. The dominant and the secondary meanings are linked as follows. The notion of function as consequence for the state of the system suggests that all phenomena in the system are considered, at least initially, as being relevant to the system's persistence. It is then but a small move to the postulate that all phenomena in a system are interrelated and that a change in one aspect will have implications for all others and for the system as a whole.
