Title: Truth, subderivations, and the Liar Sentence
Abstract: In this talk, I outline a new way of treating the Liar sentence and related semantic paradoxes. This treatment revolves around a study of the use of the truth predicate. I claim that in addition to its disquotational use, the truth predicate is also used to navigate movement between the various subderivations in a proof, and that once we modify classical logic to reflect this the Liar paradox can be defused. The talk will be mostly non-technical and so should be accessible to a wide audience; the main technical results will be motivated and discussed but not proved.
