Theorists have often returned to the work of Marx, to interpret and better understand the global developments and current political and economic crisis. This book combines an attempt to develop a specific reading of Marx with a set of interventions on crucial topics at stake in contemporary critical debates. The book is divided into two parts, with the first offers a reading of Marx on the "production of subjectivity," as a crucial test for a critical assessment of some of the most important Marxian concepts and of their potentiality for grasping the present from the point of view of its radical transformation.
