Truth and Speed-Up

Fischer, Martin (2014): Truth and Speed-Up. In: Review of Symbolic Logic, Vol. 7, No. 2: pp. 319-340

Abstract

In this paper, we investigate the phenomenon of speed-up in the context of theories of truth. We focus on axiomatic theories of truth extending Peano arithmetic. We are particularly interested on whether conservative extensions of PA have speed-up and on how this relates to a deflationist account. We show that disquotational theories have no significant speed-up, in contrast to some compositional theories, and we briefly assess the philosophical implications of these results.
