Book excerpt: A Selection of Writings on Dialectical Materialism by Marx, Engels, Lenin, Trotsky, Plekhanov, and Luxemburg, and Alan Woods. Edited by John Peterson with an Introduction by Alan Woods. On the bicentennial of his birth, Karl Marx’s ideas are more relevant than ever. While he is perhaps best known for his writings on economics and history, anyone who wishes to have a fully rounded understanding of his method must strive to master dialectical materialism, which itself resulted from an assiduous study and critique of Hegel. Dialectical materialism is the logic of motion, development, and change. By embracing contradiction instead of trying to write it out of reality, dialectics allows Marxists to approach processes as they really are, not as we would like them to be. In this way we can understand and explain the essential class interests at stake in our fight against capitalist exploitation and oppression. At every decisive turning point in history, scientific socialists must go back to basics. Marxist theory represents the synthesized experience, historical memory, and guide to action of the working class. The Revolutionary Philosophy of Marxism aims to arm the new generation of revolutionary socialists with these essential ideas.
