Self and identity have been important yet volatile notions in psychology since its formative years as a scientific discipline. Recently, psychologists and other social scientists have begun to develop and refine the conceptual and empirical tools for studying the complex nature of self. This volume presents a critical analysis of fundamental issues in the scientific study of self and identity. These chapters go much farther than merely taking stock of recent scientific progress. World-class social scientists from psychology, sociology and anthropology present new and contrasting perspectives on these fundamental issues. Topics include the personal versus social nature of self and identity, multiplicity of selves versus unity of identity, and the societal, cultural, and historical formation and expression of selves. These creative contributions provide new insights into the major issues involved in understanding self and identity. As the first volume in the Rutgers Series on Self and Social Identity, the book sets the stage for a productive second century of scientific analysis and heightened understanding of self and identity. Scholars and advanced students in the social sciences will find this highly informative and provocative reading. Dr. Richard D. Ashmore is a professor and Dr. Lee Jussim is an associate professor in the Department of Psychology at Rutgers University, New Brunswick, New Jersey.
