Abstract

As is well known, Putnam changed his philosophical position on a number of occasions throughout his career. In this paper, I reconsider the position of internal realism which Putnam defended from the mid-1970’s until around 1990. The paper opens with a discussion of the position that Putnam called “metaphysical realism”, since his internal realism emerged out of a critique of that position. The paper then briefly presents the internal realist view as one which involves an epistemic conception of truth, as well as an anti-realist metaphysical outlook on which objects depend on conceptual scheme. The paper then provides a survey of the key objections to internal realism which emerged in the ensuing debate with defenders of realism. The paper concludes with a brief consideration of the relevance of Putnam’s later adoption of a direct realist theory of perception with respect to the issue of realism.
