Marcuse - An Essay on Liberation (Beacon, 1969)

In this concise and startling book, the author of One-Dimensional Man argues that the time for utopian speculation has come. Marcuse argues that the traditional conceptions of human freedom have been rendered obsolete by the development of advanced industrial society. Social theory can no longer content itself with repeating the formula, "from each according to his ability, to each according to his needs," but must now investigate the nature of human needs themselves.
