Pierre Macherey’sHegel or Spinoza?suggests that Hegel was driven to his now legendary misinterpretations of Spinoza because he could not accept Spinozism without compromising his own philosophy. Macherey shows us a Spinoza that pre-emptively resists and challenges Hegel’s understanding of Spirit as Subject realising itself through self-negation and contradiction. This review draws out the central arguments in the book, and those arguments most salient for contemporary theories of capitalism and revolution, and points towards possible implications for Marxist theory.
