In 1980, at the end of the most intensely political period of his work and life, Louis Althusser penned Philosophy for Non-philosophers. Available English for the first time, it constitutes a rigorous and engaged attempt to address a wide reading public unfamiliar with Althusser's project. As such, the work is a concentration of the most fundamental theses of Althusser's own ideas, and presents a synthesis of his sprawling and disparate philosophical and political writings.Philosophy for Non-philosophers is a continuation and conglomeration of Althusser's thought, that provides a vivid encapsulation of Althusser's seminal influence on the leading thinkers of today.
