The recently-released sixth volume of the Herbert Marcuse Collected Papers series, Marxism, Revolution and Utopia, includes selections of Marcuse’s correspondence with Raya Dunayevskaya, as well as his introduction to her Marxism and Freedom. In this latter document, Marcuse introduces some of the ideas he would develop at greater length in the influential One-Dimensional Man. These texts may also be found in The Dunayevskaya-Marcuse-Fromm Correspondence, 1954-1978, previously reviewed on this blog.
