Marxist Theory of Class for a Skeptical World is a critique of some of the influential radical theories of class, and presents an alternative approach to it. This book critically discusses Analytical Marxist and Post-structuralist Marxist theories of class, and offers an alternative approach that is rooted in the ideas of Marx and Engels as well as Lenin and Trotsky. It presents a materialist-dialectical foundation for class theory, and conceptualizes class at the trans-historical level and at the level of capitalism. It shows that capitalism is an objectively-existing articulation of exchange, property and value relations, between capital and labour, at multiple geographical scales, and that the state is an arm of class relation. It draws out implications of class relations for consciousness and political power of the proletariat.
