Marcel Mauss's writings on techniques and technology are at the forefront of an important anthropological and sociological research tradition, and they also highlight the theoretical and ideological challenges surrounding this field of study. A selection of Mauss's texts -- including his major statements on methodology, on body techniques, on practical reason, on nation and civilisation, on progress, and so forth -- are here translated and presented together for the first time, with a discussion of their context, impact and implications. This book will interest scholars and students dealing with the French sociological tradition, and also more generally those concerned with technology and material culture studies in archaeological, anthropological or contemporary settings.
