The contributions that the Frankfurt School offers to Psychology are varied. Specifically, its most eloquent problem was that of being able to discern the characteristics that make indivi-duals authoritarian and violent people. The concern of the Frankfurt writers centers on their own historical situations: the advent of totalitarian governments in Europe causes members to migrate to various countries. Max Horkheimer migrates to the United States where he begins to work on a second stage of his thinking, substantially aimed at reviewing (...) categories used during the 1930s as well as investigating the problem of social violence. His essay writing often hinders theoretical apprehension as a unit, but a search for his transversal concepts allows us to unders-tand his critical conception of society.I propose to outline the fundamental categories of analysis on what I call his Political Social Psychology in order to arrive at a general vision of what Psychology should be for him and what its role should be within Critical Theory.
