"Neo-Pragmatist Truth and Supervaluationism"
Deflationists about truth hold that the function of the truth predicate is to enable us to make certain assertions we could not otherwise make. Pragmatists claim that the utility of negation lies in its role in registering incompatibility. The pragmatist insight about negation has been successfully incorporated into bilateral theories of content, which take the meaning of negation to be inferentially explained in terms of the speech act of rejection. One can implement the deflationist insight in the pragmatist's theory of content by taking the meaning of the truth predicate to be explained by its inferential relation to assertion. There are two upshots. First, a new diagnosis of the Liar, Revenges and attendant paradoxes: the paradoxes require that truth rules preserve evidence, but they only preserve commitment. Second, one straightforwardly obtains axiomatisations of several supervaluational hierarchies, answering the question of how such theories are to be naturally axiomatised. This is joint work with Luca Incurvati (Amsterdam).

"Distinguishing between merely verbal disputes and metalinguistic negotiations"
Merely verbal disputes are, roughly, disputes about language that are not worthwhile. Metalinguistic negotiations, on the other hand, are roughly disputes about language which are worthwhile. Recent work suggests that some merely verbal disputes may not be problematic in this way (see, for example, Balcerak Jackson (2014), Belleri (2020) and Mankowitz (2021)). In this paper, I propose that this recent work misses one crucial point: interlocutors have to cooperate in the right kinds of ways in order for a dispute to be worthwhile. Using the question-under-discussion framework developed in Roberts (2012), I provide a form of cooperation which I show can distinguish between merely verbal disputes and metalinguistic negotiations.
If this paper is correct that sometimes what makes disputes about language worthwhile is that the interlocutors are willing to cooperate in the right kinds of ways, then there is a critical upshot: interlocutors can control whether their dispute is worth their time. That is, if interlocutors decide to treat what each other is saying as true for the purposes of the conversation, or if they manage to come to some compromise about some things they are both willing to accept as true, then they can go from having a worthless dispute to having a worthwhile one.

Talk Title: Grammar, Incrementality and fMRI Timecourse
Abstract: What is the physical basis of human language comprehension? What sort of computation makes a stream of words come together, one after another, to yield a communicative or literary experience? This question sets up a scientific challenge for the brain and cognitive sciences. With functional neuroimaging, it is possible to extract a timecourse of brain activity from particular regions and ask how well alternative (psycho)linguistic theories account for the measured signal. This can be done over prolonged periods of time, for instance during the spoken recitation of a literary text. On the basis of such timecourses, this talk argues that our conceptualization of grammar should go beyond simple word-sequences and naive phrase structure. It presents an incremental parsing strategy that is more consistent with neuroimaging data than the simple ones presented in books like Hale (2014). The overall methodology can serve as a positive example of how brain data, syntactic theory and parsing algorithms may productively co-constrain one another.
Bio: John Hale, the Arch Professor of World Languages and Cultures at the University of Georgia, is a professor in the Department of Linguistics at UGA. A computational linguist, he has made significant contributions to the theory of sentence processing over the past two decades and is the author of a valued textbook in the field (Automaton Theories of Human Sentence Comprehension, 2014). Strongly committed to cultivating the vital and also changing character of intellectual pursuit in current times, Professor Hale collaborates with DeepMind and has been active in promoting interaction between industry and academia as a way of getting to the bottom of questions about the nature of mind.

Relativized Exhaustivity: Mention-Some and Uniqueness
Wh-questions with the modal verb can admit both mention-some (MS) and mention-all (MA) answers. This paper argues that we should treat MS as a grammatical phenomenon, primarily determined by the grammar of the wh-interrogative. I assume that MS and MA answers can be modeled using the same definition of answerhood (Fox 2013) and attribute the MS/MA ambiguity to structural variations within the question nucleus. The variations are: (i) the scope ambiguity of the higher-order wh-trace, and (ii) the absence/presence of an anti-exhaustification operator. However, treating MS answers as complete answers in this way contradicts the widely adopted analysis of uniqueness effects in questions of Dayal 1996, according to which the uniqueness effects of singular which-phrases arise from an exhaustivity presupposition, namely that a question must have a unique exhaustive true answer. To solve this dilemma, I propose that question interpretations presuppose ‘Relativized Exhaustivity’: roughly, the exhaustivity in questions is evaluated relative to the accessible worlds as opposed to the anchor/utterance world. Relativized Exhaustivity preserves the merits of Dayal’s exhaustivity presupposition while permitting MS; moreover, it explains the local-uniqueness effects in modalized singular wh-questions.Contact Information: logic@uconn.edu More - 3/25Logic Colloquium: Andreas Kapsner (Munich)

"Norm Conflicts and Epistemic Modals"
Abstract:
Statements containing epistemic modals (e.g. “by autumn 2022 most European countries may have the Covid-19 pandemic under control”) are common expressions of epistemic uncertainty. In this paper, previous published findings (Knobe & Yalcin, 2014; Khoo & Phillips, 2018) on the opposition between Contextualism and Relativism for epistemic modals are re-examined. It is found that these findings contain a substantial degree of individual variation. To investigate whether participants differ in their interpretation of epistemic modals, an experiment with multiple phases and sessions is used to classify participants according to the three semantic theories of Relativism, Contextualism, and Objectivism. Through this study, some of the first empirical evidence for the kind of truth value shifts postulated by semantic Relativism is presented. It is furthermore found that participants’ disagreement judgments match their truth evaluations and that participants are capable of distinguishing between truth and justification. In a second experimental session, it is investigated whether participants thus classified follow the norm of retraction which Relativism uses to account for argumentation with epistemic modals. Here the results are less favorable for Relativism. In a second experiment, these results are replicated and the normative beliefs of participants concerning the norm of retraction are investigated following work on measuring norms by Bicchieri (2017). Again, it is found that on average participants show no strong preferences concerning the norm of retraction for epistemic modals, yet participants who had committed to Objectivism and had training in logics applied the norm of retraction to might-statements. These results present a substantial challenge to the account of argumentation with epistemic modals presented in MacFarlane (2014), as discussed.

"How Not to See Pierre: Making Sense of Absences"
There is good reason to suppose that there are absences. For example, it would appear that they can be seen. But the supposition that there are absences faces both metaphysical and epistemological problems. This talk will deploy the tools of formal mereology to show how these problems can be solved.

"Revisiting Chaitin’s Incompleteness Theorem"
In the mid-1970s, Gregory Chaitin proved a novel incompleteness theorem, formulated in terms of Kolmogorov complexity, a measure of complexity that features prominently in algorithmic information theory. Chaitin further claimed that his theorem provides insight into both the source and scope of the incompleteness phenomenon, a claim that has been subject to much criticism. In this talk, I consider a new strategy for vindicating Chaitin’s claims, one informed by recent work of Bienvenu, Romashchenko, Shen, Taveneaux, and Vermeeren that extends and refines Chaitin’s incompleteness theorem. As I argue, this strategy, though more promising than previous attempts, fails to vindicate Chaitin’s claims. Lastly, I will suggest an alternative interpretation of Chaitin’s theorem, according to which the theorem indicates a trade-off that comes from working with a sufficiently strong definition of randomness—namely, that we lose the ability to certify randomness.
