Edited by Douglas Kellner and Clayton Pierce, Philosophy, Psychoanalysis and Emancipation is the fifth volume of Herbert Marcuse’s collected papers. Containing some of Marcuse’s most important work, this book presents for the first time his unique syntheses of philosophy, psychoanalysis, and critical social theory, directed toward human emancipation and social transformation. Within philosophy, Marcuse engaged with disparate and often conflicting philosophical perspectives - ranging from Heidegger and phenomenology, to Hegel, Marx, and Freud - to create unique philosophical insights, often overlooked in favor of his theoretical and political interventions with the New Left, the subject of previous volumes. This collection assembles significant, and in some cases unknown texts from the Herbert Marcuse archives in Frankfurt, including: critiques of positivism and idealism, Dewey’s pragmatism, and the tradition of German philosophy philosophical essays from the 1930s and 1940s that attempt to reconstruct philosophy on a materialist base Marcuse’s unique attempts to bring together Freud and philosophy philosophical reflections on death, human aggression, war, and peace Marcuse’s later critical philosophical perspectives on science, technology, society, religion, and ecology. A comprehensive introduction by Douglas Kellner, Tyson Lewis and Clayton Pierce places Marcuse’s work in the context of his engagement with the main currents of twentieth century politics and philosophy. An Afterword by Andrew Feenberg provides a personal memory of Marcuse as scholar, teacher and activist, and summarizes the lasting relevance of his radical thought.
