Abstract

'Realism' is multiply ambiguous. The central concern of Part 1 of this paper is to distinguish several of its many senses -- four in which it refers to theses about the status of scientific theories, and five in which it refers to theses about the nature of truth or truth-bearers. Because 'Realism' has these several, largely independent, senses, the conventional wisdom that Tarski's theory of truth supports realism, and that the Meaning-Variance thesis undermines it, needs re-evaluation. The concern of the rest of the paper is to sort out in which senses the conventional wisdom, with respect to Tarski's theory and the Meaning-Variance thesis , is correct
