In Marx ́s Laboratory. Critical Interpretations of the Grundrisse provides a critical analysis of the Grundrisse as a crucial stage in the development of Marx ́s critique of political economy. Stressing both the achievements and limitations of this much-debated text, and drawing upon recent philological advances, this volume attempts to re-read Marx ́s 1857-58 manuscripts against the background of Capital, as a ́laboratory ́ in which Marx first began to clarify central elements of his mature problematic. With chapters by an international range of authors from different traditions of interpretation, including the International Symposium on Marxian Theory, this volume provides an in-depth analysis of key themes and concepts in the Grundrisse , such as method, dialectics and abstraction; abstract labour, value, money and capital; technology, the ́general intellect ́ and revolutionary subjectivity, surplus-value, competition, crisis; and society, gender, ecology and pre-capitalist forms. Contributors include: Chris Arthur, Luca Basso, Riccardo Bellofiore, George Caffentzis, Martha Campbell, Juan I©łigo Carrera, Howard Engelskirchen, Roberto Fineschi, Michael Heinrich, Fred Moseley, Patrick Murray, Geert Reuten, Tony Smith, Guido Starosta, Massimiliano Tomba, Jan Toporowski, Peter D. Thomas, Joel Wainwright, and Amy Wendling.
