Marx's Social Ontology argues that Marx was engaged in a single enterprise throughout his works, specially the construction of a systematic and philosophical theory of society. Organized around five basic themes of Marx social ontology society, labor, causality, freedom and justice the book examines the value theory underlying Marx's critique of modern society. In addition to elucidating one of Marx's most difficult and important works, and providing a completely new perspective for examining the whole body of literature by and about Marx, the book also raises issues of enduring and current interest, including the relationship between technology and society, the forms and prospects for socialism in the future, and the role that philosophy can play in understanding and resolving social issues.
