The Unity of Logical Consequence
Lavinia Picollo will be giving a talk entitled “The Unity of Logical Consequence” at the Virtual International Consortium of Truth Research on October 12, 2020 at 10:00 am EDT.
Abstract: The two traditional approaches to formal validity, i.e. the semantic, in terms of semantic clauses and truth preservation, and the syntactic, in terms of rules of inference and the availability of proofs, are often conceived of as rivals. I show, to the contrary, that, modulo a deflationary account of truth and satisfaction, semantic clauses and inference rules turn out to be conceptually equivalent (in a sense to be explained). As a result, the two approaches to logical consequence conceptually converge too. I conclude as well that, unlike what is normally believed, deflationism is not incompatible with truth-conditional semantics (for logical terms) and semantic approaches to logical consequence.

Lavinia Picollo is a Lecturer in Philosophy at UCL. She received her PhD from the University of Buenos Aires in 2015. After that she spent a year as a postdoctoral fellow at the Center for Advanced Studies and two years as an Assistant Professor at the Munich Center for Mathematical Philosophy (MCMP), both at LMU Munich. Her research is in philosophical logic, formal metaphysics, and the philosophy of logic and mathematics. She has a special interest in reference and content, deflationary conceptions of truth and satisfaction, propositions, properties, and classes, second-order logic, absolute generality, neologicism, logical pluralism, logicality, logical constants, and logical consequence. She’s also interested in ontology, epistemology, philosophy of language, and metaphysics.
