Abstract

This paper, an extract from my Marxism and Materialism: Studies in Marxist Theory of Knowledge, discusses the epistemological status of philosophical realism. I take realism to be a necessary part of what Marx meant by 'materialism'. I argue that there are no valid, non-question-begging, decuctive arguments for the truth of realism; nor does empirical science inductively 'confirm' realism, in any technical sense of 'confirmation'. I argue that the relationship between realism and science is one of methodological continuity, in a sense difficult to specify exactly, since the denial of the essential independence from the mind of the material world ends in theology, at least in the tradition of absolute idealism. I then examine Lenin's Materialism and Empirio-Criticism, in which I claim to find the same argument about methodological continuity, and show how this claim might be applied to the tradition of subjective idealism, with its use of counterfactuals and logically possible experiences in the 'reduction' of the physical world to experience.
