The centenary of Marx's death provides the occasion for reconsidering his life and works and the continuing influence of his thought. David McLellan and his colleagues, in essays on history, economics, politics, sociology, philosophy and culture, find him not only still relevant (though not infallible) but also a challenge to further exploration and creative thinking. They are also agreed in seeing nothing creative in the theories and practices of the authoritarian-bureaucratic states where Marxism is the officially proclaimed doctrine. This point has been the familiar theme of the American political philosopher Sidney Hook over the past half century. Marxism and Beyond is a collection of his writings, all but a few previously published and many of them worth re-reading.
