Turning the tables : inference and truth
Résumé
Deflationism about truth is the thesis that truth is a "thin" or "nonsubstantial" property the meaning of which is entirely given by the tarskian T-equivalences (or T-rules) . " True ", it is said is useful for expressing some generalisations but it is devoid of any "real" explanatory power. A problem with this view is that it has proved difficult to render this " non-substantiality " claim precise. The aim of this paper is to show that the deflationist could take it to mean that truth is a kind of logical property and that this answer is in harmony with the deflationist's methodological commitments and some classical insights on logicality coming from philosophical proof-theory.
