Part of the SAGE Social Thinkers series, this brief and clearly-written book provides a concise introduction to the work, life, and influences of Karl Marx, one of the most revered, reviled, and misunderstood figures in modern history. The book serves as an excellent introduction to the full range of Marx’s major themes―alienation, economics, social class, capitalism, communism, materialism, environmental sustainability―and considers the extent to which they are relevant today. It is ideal for use as a self-contained volume or in conjunction with other sociological theory textbooks.
