Scharp on replacing truth

摘要

Kevin Scharp's 'Replacing Truth' is an ambitious and far reaching account of the semantic paradoxes. In this critical discussion we examine one the books central claims: to have provided a theory of truth that avoids the revenge paradoxes. In the first part we assess this claim, and in the second part we investigate some features of Scharp's preferred theory of truth, ADT, and compare it with existing theories such as the Kripke-Feferman theory. In the appendix a simple model of Scharp's theory is presented, and some potential consistent ways to strengthen the theory are suggested.
