 The revision theory of truth starts with the idea that we may take the T-schema at face value. Indeed, Gupta and Belnap (1993) take up a suggestion from Tarski (1944), that the instances of the T-schema can be seen as partial definitions of truth; presumably with all the instances together, for the right language or family of languages constituting a complete definition. At the same time, the revision theory holds fast to classical logic. Thus, we already know, we have the Liar paradox for any language with enough expressive resources to produce Liar sentences.
