Book excerpt: This book investigates the relation between Durkheim’s sociology, Critical Theory, and the philosophy of social sciences. The book is organized in four sections: confronting Durkheim and other critical traditions; inquiring his social and critical ontology; interrogating the relation between social practices and justice; and discussing his relevance in contemporary politics and political theory. An international group of philosophers, sociologists, and critical theorists contribute to show Durkheim’s reflection as an important complement—or an alternative—to the Hegelian-Marxist and post-structuralist conceptions of social critique. In this way, the book intends to inaugurate a new reflection on social critique at the intersection between philosophy and sociological theory.
