Book excerpt: In a careful exposition of French Marxism, William Lewis places Althusser and his thought alongside the pre- and post-war French communist intellectual climate: the result is an excellent and unique work. Part theoretical treatise on some of Althusser's more complicated and less explored ideas, part intellectual history, Louis Althusser and the Traditions of French Marxism is, in total, an important text for philosophy, French and francophone studies, political thought, cultural studies, marxist thought, and several other disciplines interested in the intellectual life and times of the twientieth century.
