The prevailing view among social scientists is that the psyche and the social reside in such disparate domains that their proper study demands markedly incompatible analytical and theoretical approaches. Over the last decade, scholars have begun to challenge this view. In this innovative work, George Cavalletto moves this challenge forward by connecting it to theoretical and analytical practices of the early 20th century. His analysis of key texts by Sigmund Freud, Max Weber, Theodor Adorno and Norbert Elias shows that they crossed the psycho-social divide in ways that can help contemporary scholars to re-establish an analytical and theoretical understanding of the inherent interconnection of these two domains. This book will particularly interest scholars and students in sociology and social psychology, especially those in the fields of social theory, the sociology of emotion, self and society, and historical sociology.
