A clear and accessible account of Marx's method and an assessment of its scientific validity and relevance to contemporary social science. David Walker provides a clear analytical account of Marx's method and considers the claims of Marxism to be a science by measuring Marx's method against different models of science. The key methodological themes of Marx's work and their development are shown with particular attention paid to the elements of dialectics and materialism. Four models of science are positivism; critical rationalism; scientific conventionalism and scientific realism. The author concludes that Marx's method is a good example of scientific realism.
