While social theory and legal theory were once closely intertwined, contemporary American sociology pays scant attention to recent developments in legal theory. But the problems that legal theory currently wrestles with are very similar to those with which sociology is now centrally concerned. This essay reviews major schools of thought in contemporary legal theory to introduce sociologists to some potentially useful literatures on the meaning of rationality; on critical theory; on the importance of gender, race, and class in understanding social institutions; on the interpretive turn; on the relationship between structure and agency; and on the revival of pragmatism.
