Critical theory draws on Marxism, psychoanalysis, postmodern and poststructuralist theorists.

This book, written for clinicians and social scientists, explores these overarching themes, focusing on the reception of Freud in America, the authoritarian personality and American politics, Lacan “return to Freud,� Jordan Peterson and the Crisis of the Liberal Arts, and the anti-psychiatry movement.
