The distinguished sociologist Peter Blau has opened up a variety of fields with brilliant contributions, ranging from research on social networks of small groups and quantitative studies of formal organizations to more synoptic investigations of populations and the large scale structures which hold them together. In this capstone to a prolific career, he has brought together these concerns to form a wide ranging theory of population structures and their influence on social life—from opportunities in job choice and social mobility, to organizational participation, and intergroup relations. Blau begins by outlining the influences of population structures on intergroup relations and then examining the implications these influences have on occupational opportunities. He looks at the many groups within which an individual is likely to socialize—family, ethnic group, socioeconomic class—and the distance away from these groups an individual is likely to move. Blau demonstrates how such factors affect social mobility, which, in turn, influences membership and structures several types of organizations. Blau then moves on to interpersonal relationships and analyzes the social exchanges in them that reveal the ultimate effects of ethnic, socioeconomic, and other aspects of population structures. He defines two types of power: influence in direct interpersonal exchange, and large-scale domination (economic or political) of groups without personal contact.

Should a court order medical treatment for a severely disabled newborn in the face of the parents' refusal to authorize it? How does the law apply to a neighborhood that objects to a group home for developmentally disabled people? Does equality mean treating everyone the same, even if such treatment affects some people adversely? Does a state requirement of employee maternity leave serve or violate the commitment to gender equality? Martha Minow takes a hard look at the way our legal system functions in dealing with people on the basis of race, gender, age, ethnicity, religion, and disability. Minow confronts a variety of dilemmas of difference resulting from contradictory legal strategies―strategies that attempt to correct inequalities by sometimes recognizing and sometimes ignoring differences. Exploring the historical sources of ideas about difference, she offers challenging alternative ways of conceiving of traits that legal and social institutions have come to regard as "different." She argues, in effect, for a constructed jurisprudence based on the ability to recognize and work with perceptible forms of difference. Minow is passionately interested in the people―"different" people―whose lives are regularly (mis)shaped and (mis)directed by the legal system's ways of handling them. Drawing on literary and feminist theories and the insights of anthropology and social history, she identifies the unstated assumptions that tend to regenerate discrimination through the very reforms that are supposed to eliminate it. Education for handicapped children, conflicts between job and family responsibilities, bilingual education, Native American land claims―these are among the concrete problems she discusses from a fresh angle of vision. Minow firmly rejects the prevailing conception of the self that she believes underlies legal doctrine―a self seen as either separate and autonomous, or else disabled and incompetent in some way. In contrast, she regards the self as being realized through connection, capable of shaping an identity only in relationship to other people. She shifts the focus for problem solving from the "different" person to the relationships that construct that difference, and she proposes an analysis that can turn "difference" from a basis of stigma and a rationale for unequal treatment into a point of human connection. "The meanings of many differences can change when people locate and revise their relationships to difference," she asserts. "The student in a wheelchair becomes less different when the building designed without him in mind is altered to permit his access." Her book evaluates contemporary legal theories and reformulates legal rights for women, children, persons with disabilities, and others historically identified as different. Here is a powerful voice for change, speaking to issues that permeate our daily lives and form a central part of the work of law. By illuminating the many ways in which people differ from one another, this book shows how lawyers, political theorist, teachers, parents, students―every one of us―can make all the difference,
