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.

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 recent years, academic philosophers have increasingly pursued what is now called “public philosophy.” Almost everyone agrees that this development is positive. But what is public philosophy? What should it be? And why does it matter? Looking back to models both ancient and modern, this talk will be an exercise in public philosophy that explores the nature and value of public philosophy.
A reception will follow the lecture.

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.

Structural causal models lend themselves to an analysis of counterfactuals – a structural semantics of counterfactuals. The basic idea is that a causal model allows for the clear and precise evaluation of any counterfactual encoded by it. Many argue that a structural semantics is superior to a more traditional similarity semantics, in part due to the latter’s independence from any notion of similarity(Galles & Pearl, 1998; Gallow, 2016; Hiddleston, 2005; Hitchcock, 2018; Pearl, 2000; Starr, 2019). I argue, though, that this is too quick. A similarity semantics employs the notion of similarity to answer what Priest (2018) calls the importation problem– the question of what information is to be held fixed in a counterfactual evaluation. I argue that where similarity semantics relies on an unarticulated notion of similarity, a structural semantics relies on an unarticulated notion of aptness. The superiority of structural semantics depends on its ability to deliver on a principled guide to determining which model(s) is apt. In this talk I go some way towards providing this guide.

“What is Democracy? is the latest movie from Astra Taylor, the world’s foremost philosophy documentarian. It chronicles conversations with middle schoolers, workers, activists, and political philosophers about what democracy is, its promises and pitfalls, and how to strengthen it. On Wednesday, April 17th at 7:00 PM, Taylor is coming to Brooklyn to present a free screening of the film. Afterwards, she will be joined by the political philosopher Nancy Fraser for a discussion of themes from the movie. If you know who either of these people are, you will understand how ridiculously excited I am for this.
As usual, we meet at the Dweck Center at the Grand Army Plaza branch of the Brooklyn Public Library. Here’s the Facebook event. Please note that this event begins at 7:00 PM. Tell and bring everybody.”

K. Fine: A Truthmaker Semantics for Conditional Imperatives
I provide a truth-maker semantics for conditional imperatives and indicate how it might be extended to other conditional constructions.
F. Moltmann: Underspecification of Attitudes and Truthmaker Semantics
It has been argued that the satisfaction conditions of a desire can be underspecified by the complement clause. This provides support for the view according to which the complement clause gives a partial content of the reported desire, where partial content is formulated in terms of truthmaker theory. In this talk, I will discuss the extent of such underspecification and whether it truly supports a truthmaker-based approach to the content of attitudes.
Optional preparatory reading here.
F. Faroldi: Truthmaker Semantics for Justification Logics – Open Problems
Justification logics are a family of logic where "implicit" modal operators are substituted by explicit terms to get formulas of the form t : A, where t could be evidence, a reason, etc. why A is known, believed, obligatory, etc., thus resulting in an “objectual” approach to modalities. In this talk we explore how to give a truthmaker semantics for justification logics, we provide some philosophical reasons to do so, and note some technical open problems.
Cian Dorr: Truthmaking in the Object Language
I consider a simple language with Boolean connectives, sentential variables and quantifiers binding them, and a connective for propositional identity (‘for it to be the case that … is for it to be the case that …’). Using familiar techniques, the possible-worlds model theory for such a language can be ‘internalised’ to derive a theory stated in the language itself, based on the definition of ‘world-proposition’ as ‘maximal consistent proposition’, and this theory can be shown to follow from the theory that propositions form a complete atomic Boolean algebra. In this paper, I will consider to what extent something similar can be done for Fine’s truthmaker semantics. This will involve looking for a way of picking out a class of special propositions to serve as surrogates for the states, and a binary relation among propositions to serve as a surrogate for the verification relation, and using these definitions to rewrite the metalinguistic definition of a model as theory in the object-language. I will make a start at considering to what extent the axioms of this theory can be derived from an independently natural weakening of the theory that propositions form a complete atomic Boolean algebra.
