Oxford's Very Short Introductions series offers concise and original introductions to a wide range of subjects -- from Islam to Sociology, Literary Theory to History, and Archaeology to the Bible. Not simply a textbook of definitions, each volume provides trenchant and provocative -- yet always balanced and complete -- discussions of the central issues in a given discipline or field. Every Very Short Introduction gives a readable evolution of the subject in question, demonstrating how the subject developed and how it influenced society. Eventually, the series will encompass every major academic discipline, offering all readers an accessible and abundant reference library. Whatever area of study one deems important or appealing, whatever topic fascinates the general reader, the Very Short Introductions series has a handy and affordable guide that will likely prove indispensable. Peter Singer identifies the central vision that unifies Marx's thought, enabling us to grasp Marx's views as a whole. He sees him as a philosopher primarily concerned with human freedom, rather than as an economist or a social scientist. In plain English, he explains alienation, historical materialism, the economic theory of Capital, and Marx's ideas of communism, and concludes with an assessment of Marx's legacy.
