 In the instances of schema (T) (sometimes called “Convention (T)”), the ‘\(X\)’ gets filled in with a name of the sentence that goes in for the ‘\(p\)’, making (T) a version of (ES). Tarski considered (T) to provide a criterion of adequacy for any theory of truth, thereby allowing that there could be more to say about truth than what the instances of the schema cover. Given that, together with the fact that he took the instances of (T) to be contingent, his theory does not qualify as deflationary.
