The political and ideological turmoil of the late 1960's stimulated among Anglo-American philosophers a new interest in applying moral philosophy to the problems of contemporary society, and a search for critical perspectives on Marx and Marxist thought. These essays, originally published in Philosophy & Public Affairs, contribute to both these areas in the form of new Marxist scholarship and in illuminating the way in which Marxist criticism and social theory bear on contemporary analytic moral philosophy and current moral problems. Originally published in 1980. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
