BELLAH, ROBERT NEELLY

born Feb. 23, 1927, Altus, Okla., U.S. American sociologist who addressed the problem of change in modern world religious practice and who offered innovative procedures for reconciling traditional religious societies with social change. Educated at Harvard University, where he received his B.A. (1950) and Ph.D. (1955), Bellah taught at the Institute for Islamic Studies at McGill University (1955-57) and the Center for Middle Eastern Studies at Harvard (1957-58). After a Fulbright scholarship to study in Japan (1960-61), Bellah returned to Harvard (1961-66). In 1967 he became Elliott professor of sociology and comparative studies at the University of California at Berkeley. His influential work Beyond Belief: Essays on Religion in a Post-Traditional World (1970) applies economic theory to culture. Varieties of Civil Religion (1980) expresses Bellah's belief that the "civil" religion inherent in educational and legal systems should be encouraged because of its openness and tolerance.
