New Book: Saul Kripke on Modal Logic

A new book celebrating Saul Kripke’s singular contributions to modal logic, Saul Kripke on Modal Logic, has just been published by Springer. It was edited by Yale Weiss and Romina Birman.

Saul Kripke on Modal Logic (Cover)

The volume features two previously unpublished pieces by Saul Kripke, a brief intellectual biography recounting the story of how Kripke became involved in modal logic, and a number of contributions dealing with the cutting edge of modal logic.

The Myth of the Ungiven

The Saul Kripke Center is pleased to announce that Kit Fine (Silver Professor and University Professor of Philosophy and Mathematics at NYU) will deliver the 6th Saul Kripke Lecture on October 31st, 2024, from 4:00 to 6:30 pm. The talk is free and open to all, and will be held in-person only at the CUNY Graduate Center (Room C198).

Title: The Myth of the Ungiven

Abstract: The notion of a borderline case has been thought to be central to our understanding of vagueness. I shall argue that there is no intelligible notion that can play this role and that an alternative framework for understanding vagueness needs to be found.

Modal definability and Kripke’s theory of truth

The Saul Kripke Center is pleased to announce that James Walsh (Assistant Professor, Philosophy, NYU) will deliver a talk on Friday, May 10th, 2024, from 4:15 to 6:15 pm at the CUNY Graduate Center (Room 9207). The talk is free and open to all.

Title: Modal definability and Kripke’s theory of truth

Abstract: In Outline of a Theory of Truth, Kripke introduces some of the central concepts of the logical study of truth and paradox. He informally defines some of these–such as groundedness and paradoxicality–using modal locutions. We introduce a modal language for regimenting Kripke’s informal definitions and characterize the modally definable sets. Though groundedness and paradoxicality are expressible in the modal language, we prove that intrinsicality–which Kripke emphasizes but does not define modally–is not.
