I shall discuss some of the issues concerning a notorious doctrine of Frege that sentences are names of truth-values. I am interested in a problem raised by Kripke that the doctrine obscures the distinction between judgeable and unjudgeable contents. I shall present what I take to be Frege’s account of judgeable content. A proper expression of a judgeable content, for Frege, is susceptible to an analysis into a predicate and an argument-word, where a predicate is understood as a concept-word used to attribute a certain property to the referent of the argument-word. In the light of this analysis, I shall argue that the doctrine does not obscure the distinction. The problem will also be discussed within the formal context of Grundgesetze. A new light will be shed on his rather peculiar conception of the symbol ‘|-’.
The Saul Kripke Center is pleased to announce that Dongwoo Kim (PhD student, Philosophy, CUNY Graduate Center) will deliver the third Saul Kripke Center Young Scholars Series talk on Thursday, March 7, 2019, from 4:30 to 6:30 in room 6495 of the CUNY Graduate Center.
Two proof-systems P and P* are said to be complementary when one proves exactly the non-theorems of the other. Complementary systems come as a particular kind of refutation calculi whose patterns of inference always work by inferring unprovable conclusions form unprovable premises. In the first part of my talk, I will focus on LK*, the sequent system complementing Gentzen’s system LK for classical logic. I will show, then, how to enrich LK* with two admissible (unary) cut rules, which allow for a simple and efficient cut-elimination algorithm. In particular, two facts will be highlighted: 1) for any given provable sequent, complementary cut-elimination always returns one of its simplest proofs, and 2) provable LK* sequents turn out to be “deductively polarized” by the empty sequent. In the second part, I will observe how an alternative complementary sequent system can be obtained by slightly modifying the Gentzen-Schütte system G3. I will finally show how this move could pave the way for a novel approach to multi-valuedness and proof-theoretic semantics for classical logic.
Russell proved over a century ago that a naive conception of structured propositions is inconsistent. Hodes (2015), Dorr (2016), and Goodman (2017) have recently reformulated Russell’s argument in the language of higher-order logic, and concluded from it that distinctions in reality cannot always reflect all the syntactic structure of the language in which we draw those distinctions. But they also float the idea that such distinctions might nevertheless have sentence-like structure, so long as this structure fails to neatly correspond to the syntactic structure of the sentences we use to draw those distinction. Perhaps, that is, the popular metaphor of facts being like sentences written in God’s “book of the world” is tenable after all. In this talk I’ll give a way of making this metaphor precise, and prove a new limitative result showing that, given natural assumptions, it too is inconsistent.

What does a philosopher look like? Inevitably, our mental pictures are shaped by the dominant imagery of the white male marble busts of Greco-Roman antiquity—Plato, Aristotle, Cicero, Seneca—and their modern European heirs—Hobbes, Descartes, Locke, Rousseau, Kant, Hegel, Mill. Even today Western philosophy is largely male and overwhelmingly white—about 97 percent in the U.S., close to 100 percent in Europe. Diversifying the field requires expanding our corporeal imaginary of its practitioners. This conference, timed to honor Professor Anita Allen-Castellitto (Penn), the first black female President in the 100-year-plus history of the American Philosophical Association, aims to showcase the work of a traditionally under-represented population, challenging these preconceptions. Allen and fifteen other black women will speak on their research across a wide variety of philosophical topics.

Two ways of giving an epistemic justification of basic logical principles will be introduced, intuition-based accounts and concept or meaning constitution-based accounts. We will briefly consider different versions of these views and argue that they face parallel dilemmas. While ‘robust’ accounts are subject to what I call the ‘adoption problem,’ ‘weak’ accounts fail to ground our basic inferential dispositions. Either way, intuitions and meaning-constituting rules turn out to be irrelevant. A more general moral for the epistemology of logic and its priorities will be drawn from the discussion.

Abstract: I provide a truth-maker semantics for the conditional and consider the application to imperative and deontic conditionals.

In my talk I argue for the thesis CT: contradiction is the norm of truth, and ask about its relevance for contemporary philosophical logic. I first present three positions in the history of philosophy that have advocated some versions of CT, namely Plato’s idea of the “dialectical gymnastics” in the Parmenides (Plato, Parmenides 136 B-E), Aristotle’s notion of dialectics in the Topics (Aristotle, Topics I, 2-3) and Metaphysics (Aristotle, Met III 1, 995 a 24-29), and Hegel’s contradictio est regula veri (Hegel Werke 2, 533), then derive from them some answers to the questions:
What is meant by “contradiction” in CT?
What is meant by “truth” in CT?
What is meant by “norm” in CT?
I will show that to examine the meaning of CT in historical perspective is useful to understand the seeds of genuine glut theories.

In this talk I will do three things. First: I will present the central results from Barrio, Pailos and Szmuc’s recent paper “A hierarchy of classical and paraconsistent logics” (forthcoming in the JPL) along with some generalizations derived by observing certain symmetries; second, I will discuss the relation between the strict tolerant logics and classical logic, K3 and LP; third, I will try to convey the exact state of uncertainty about the philosophical significance of the foregoing I find myself in on the day.
