 There is no generally agreed upon solution to the semantic paradoxes. One typical way out attempted by the supporters of truth value gaps, for instance, consists in denying that the notion of gap, or defective sentence, or sentence whose truth value is indeterminate, can be fully expressed in the language for which they are proposing their theory of truth. The strengthened paradoxes then seem to force the consistent theorist to admit that the proposed theory was formulated in a language different from, and expressively more powerful than, the one whose semantics it was supposed to express. This entails a limitation of the Tarskian T-schema characterising truth, i.e., of the equivalence
