Title: Partial identity and mereotopology Abstract: How should we think about the ways in which identity and parthood interact? One important line of thought comes from the joint influence of the two Davids: Armstrong and Lewis. The underlying idea is that mereological overlap is a kind of identity 鈥� namely, partial identity. The aim of…

Title: Relevance in the Logic of Imagination Abstract: Reality-oriented mental simulation is a kind of imagination. The working assumption is that, when trying to determine whether a match would light if struck, one initially imagines striking the match and, together with relevant beliefs imported into the imaginative scenario, mentally simulates what would happen. But what…

Title: Composition as Identity defeats an Ethical Objection to Four-Dimensionalism Abstract: Johnston, Olson, and Taylor have argued against four-dimensionalism on the grounds that it commits us to the existence of personites, which are proper temporal parts of four-dimensional persons. They argue that the existence of personites makes many of our moral beliefs and practices untenable,…

Title:聽Worlds: Possible and Impossible Abstract: In this talk, I鈥檒l reflect on the role of worlds鈥攂oth possible worlds and impossible worlds鈥攂oth in the聽semantics of various kinds of languages and logics, and in broader issues in metaphysics. I will argue that, given very modest assumptions concerning the role of worlds in semantics, that any defender of possible…

Title: Properties and Their Parts Abstract: I will present some very early ideas on a hyperintensional theory of properties that I am attempting to work out. I will begin my presentation by considering an unlikely area of inquiry: the mereology of material objects. I will offer a framework for thinking about two distinct types of…

Title:聽Impossible Worlds in Dynamic Epistemic Logic Abstract:聽Epistemic Logic, as a spinoff of normal modal logics, suffers from the problem of logical omniscience: its agents are perfect reasoners with unlimited deductive power. We argue that, even from a normative point of view, this modelling is inadequate for it sets requirements that cannot be actually attained according…

Title: On Beall and Camrud’s defence of the combinatorial argument for FDE Abstract:聽In their 2020 paper “FDE all the way up”, Beall and Camrud aim to defend a particular combinatorial argument for the paraconsistent and paracomplete logic FDE against a natural objection. The argument, roughly, states that, since logic must consider all possibilities, it is…

Title: Logical Akrasia Abstract:聽The aim of this paper is two-fold. First, it introduces the concept logical akrasia (by analogy to epistemic akrasia). Second, it discusses how logical akrasia relates to the standards of epistemic rationality, and in particular, how logical akrasia might pose a challenge to the tenability of the controversial 铿亁ed point thesis.

Title: Intensional Subject-Matter in Subsystems of Analytic Implication Abstract: Although one tends to think of truth or falsity as the predominant semantic feature with which logic is concerned, a number of logics exist that give the feature of topic or subject-matter equal weight. Just as we expect compositional truth conditions to extend to the entirety…

Title: The Access Problem for Act-type Theories of Propositions Abstract: Recent work on propositions has seen the rise of act-type theories, according to which propositions are types of cognitive acts that derive their representational and truth-conditional properties from the token cognitive acts of agents. Act-type theories have been gaining traction as part of a rejection…

Title: Explanatory (or Grounding) Proofs: Philosophical Framework, Core Ideas, Results Abstract: When it comes to the question of聽what聽proofs serve for, since the antiquity聽two possible answers have been identified: on the one hand, a proof can serve to show that something is true,聽on the other hand, a proof can also serve to explain why something is…
