Knowledge, communication, action - these are the concepts central to all of Habermas's thought. As a philosopher, he is concerned with the rational connection of these concepts. As a sociologist, he is prepared to analyze with care the distortion of human interaction caused by existing social and political institutions.

Herbert Marcuse's Negations is both a radical critique of capitalist modernity and a model of materialist dialectical thinking. In a series of essays, originally written in the period stretching from the 1930s to 1960s, Marcuse takes up the presupposed categories that have, and continue to, ground thought and action in our administered society: liberalism, industrialism, individualism, hedonism, aggression. This book is both a testament to a great thinker and a still vital strand of thought in the comprehension and critique of the modern organized world. It is essential reading for younger scholars and a radical reminder for those steeped in the tradition of a critical theory of society. With a brilliance of conception combined with an insistence on the material conditions of thought and action, this book speaks both to the particular contents engaged and to the fundamental grounds of any critique of organized modernity.

Universities must transmit technically exploitable knowledge. That is, they must meet an industrial society's need for qualified new generations and at the same time be concerned with the expanded reproduction of education itself. In addition, universities must not only transmit technically exploitable knowledge, but also produce it. This includes both information flowing from research into the channels of industrial utilization, armament, and social welfare, and advisory knowledge that enters into strategies of administration, government, and other decision-making powers, such as private enterprises. Thus, through instruction and research the university is immediately connected with functions of the economic process.

"For those concerned with the relationships between thought and action, KNOWLEDGE AND HUMAN INTERESTS will quickly be recognized as a brilliant book -- and a bold outline for a new social theory." (Times Literary Supplement)
