Lewis A. Coser

Lewis Coser (Berlin, 27 November 1913 – Cambridge, Massachusetts, 8 July 2003) was a German-American sociologist, serving as the 66th president of the American Sociological Association in 1975.

Born in Berlin as Ludwig Cohen, Coser first taught at the University of Chicago and the University of California. He then founded the sociology department at Brandeis University and taught there for 15 years before joining the sociology department of the State University of New York at Stony Brook.

Coser was the first sociologist to try to bring together structural functionalism and conflict theory; his work was focused on finding the functions of social conflict. Coser argued - with Georg Simmel - that conflict might serve to solidify a loosely structured group. In a society that seems to be disintegrating, conflict with another society, inter-group conflict, may restore the integrative core. For example, the cohesiveness of Israeli Jews might be attributed to the long-standing conflict with the Arabs. Conflict with one group may also serve to produce cohesion by leading to a series of alliances with other groups.

Conflicts within a society, intra-group conflict, can bring some ordinarily isolated individuals into an active role. The protest over the Vietnam War motivated many young people to take vigorous roles in American political life for the first time.

Conflicts also serve a communication function. Prior to conflict, groups may be unsure of their adversary’s position, but as a result of conflict, positions and boundaries between groups often become clarified, leaving individuals better able to decide on a proper course of action in relation to their adversary.
