A Metaphilosophical Analysis of the Core Idea of Deflationism

In this paper, I give a metaphilosophical analysis of the core idea of deflationism by discussing some basic conceptual and methodological issues involved in the debate between deflationism and substantivism. In so doing, I argue for three positive points. First, the crux of the dispute between deflationism and substantivism is whether or not truth is substantive in its metaphysical nature and in its explanatory role in philosophical enterprises, rather than whether or not a minimal approach regarding conceptual resources is taken to explain truth; a minimal approach itself is philosophically innocent. Second, there is no intrinsic connection between the core idea of deflationism and the Tarski‐style equivalence thesis, which is often identified as implying or supporting the former. Third, there are some unbridged fundamental gaps between the core idea of deflationism and various redundancy theses; these redundancy theses cannot be identified as the former, nor can they be used to justify the former on their own.
