Psychoanalysis and the Human Sciences translates Althusser's remarkable seminars into English for the first time, making available to a wider audience the origins and potential future of radical political theory. Althusser takes the important step in these lectures of distinguishing psychoanalysis from psychology and especially psychiatry, which long resisted Freud's analytical concepts of the unconscious and overdetermination. By freeing psychoanalysis from this bind, Althusser can then apply these analytical concepts to the social and the political, integrated with Marxist theory. The result is an enlivened methodology for comprehending social organization and change that had a profound influence on the Frankfurt School and scholars who continue to work at the forefront of radical thought today: Judith Butler, Etienne Balibar, and Alain Badiou.
