This brilliant and original book sets out to dismantle the idea that movements, crises and other phenomena produced in society must be explained by exclusively social causes, without recourse to psychological explanations. The author argues that we should reassess the significance of psychological causes in human affairs. Whilst psychological causes are undoubtedly distinct from social causes, all social phenomena are events or facts brought about by human beings: it is their passions which stimulate their great political, religious and cultural creations. He discusses the work of Durkehim, Mauss, Weber and Simmel, and argues that only a productive interplay between psychology and sociology will do justice to the interdisciplinary character of their thought. Winner of the European Amalfi Prize for Sociology, The Invention of Sociology will be welcomed by students and researchers in sociology, social psychology, and the social sciences generally.
