This important collective work encompasses nearly a century of psychological theory situated at the various intersections of Marxism with psychology and psychoanalysis. The compiled classic and current texts, all of them preceded by unpublished introductions, display the theoretical depth and political radicalism of a critical Marxist tradition in which not only the dominant psychology is questioned, but alternative psychological models are proposed. Crucial moments and influential authors in the historical development of the conception of subjectivity in Marxism are highlighted, but this history is also reactivated for the present. Psychology and psychoanalysis cannot but be revolutionized under the effect of the vigorous Marxist challenge of our bourgeois world, of the capitalist system and its ideological and disciplinary devices.
