Wolff provides a masterful summary of Marxist thought in this short and to the point book. The Marxist take on religion, politics and economics are all well handled, and the book ends with Wolff expressing succinctly his own view of Marxist thought. The book begins with biographical facts about Marx, his early thought, his relationship with Engels, the First International, his view of religion, his criticism of capitalism, and his proposals for a communist society that might replace it.
The book itself is a short and accessible paperback written in an easy style. Fuller puts Marx in context well without getting too involved or detailed. This book is a brilliant introduction. Recommended highly.
