A new annotated translation of Gabriel Tarde's "Deux éléments de la sociologie", in which Tarde critiques Emile Durkheim's sociology, offering a polemical demolition of Durkheim's rejection of biology. As editor Matei Candea puts it in the preface to the second edition, this new translation "neatly illustrates... the question of how, precisely, Tarde's metaphysics and his human-focused sociology fit together. A question which is not merely of antiquarian or historical interest, but which echoes both in the contemporary rediscovery of this work, and in the social sciences and humanities more broadly at the present juncture."
