In A Philosophy for Communism: Rethinking Althusser Panagiotis Sotiris attempts a reading of the work of the French philosopher centered upon his deeply political conception of philosophy. Althusser’s endeavour is presented as a quest for a new practice of philosophy that would enable a new practice of politics for communism, in opposition to idealism and teleology. The central point is that in his trajectory from the crucial interventions of the 1960s to the texts on aleatory materialism, Althusser remained a communist in philosophy. This is based upon a reading of the tensions and dynamics running through Althusser’s work and his dialogue with other thinkers. Particular attention is paid to crucial texts by Althusser that remained unpublished until relatively recently.
