On the occasion of the publication of the translation of Pierre Raymond’s text on Althusser’s materialism, we attempt an introduction to his theoretical trajectory. We begin with his conception of the conflict between materialism and idealism in Le passage au matérialisme in 1973 and his thinking on the question of the history of sciences in L’histoire & les sciences (1975), before turning our attention to his elaboration on the question of a history of mathematics and in particular of the emergence of probabilistic reasoning. Then we examine his confrontation with the question of the relation between materialism and dialectics in Matérialisme dialectique et logique. After that, we proceed to his conception of the need to break with any form of teleology and finalism as the starting point for a new conception of causality (La résistible fatalité de l’histoire of 1982), before looking at Dissiper la terreur et les ténèbres of 1992 and his attempt to rethink the question of practical reason. It is in light of the above presentation that we insist on the importance of Raymond’s text on Althusser.
