Acad. Mircea Dumitru va conferenția la CUNY cu tema „Truth with and without satisfaction” în 27 noiembrie 2023
The Logic and Metaphysics Workshop will meet on November 27th from 4:15-6:15 (NY time) in-person at the Graduate Center (Room 4419) for a talk by Mircea Dumitru (Bucharest).
Title: Truth with and without satisfaction
Abstract: The talk addresses a quite natural situation in mathematics. When one needs to define a concept and it is not possible to do a direct recursion on the concept itself, what one does is the next best thing which is to perform recursion on a related concept of which the original given concept can be shown to be a special case. Tarski, in his celebrated paper on “The Concept of Truth in Formalized Languages”, cannot give a definition of truth performing direct recursion on the concept of truth itself. Consequently, he settles on a definition in terms of satisfaction. Following Kit Fine and Timothy McCarthy, “Truth without Satisfaction”, I raise the issue of whether such an indirect procedure of giving a definition of truth is necessary or maybe an alternative definition of truth can be given without going through the related concept of satisfaction. My talk will investigate both certain technical and philosophical aspects of the two sets of formal constraints to defining truth with and without satisfaction.
