  • Doctors without ‘Disorders’
    Aristotelian Society Supplementary Volume 94 (1): 163-184. 2020.
    On one influential view, the problems that should attract medical attention involve a disorder, because the goals of medical practice are to prevent and treat disorders. Based on this view, if there are no mental disorders then the status of psychiatry as a medical field is challenged. In this paper, I observe that it is often difficult to establish whether the problems that attract medical attention involve a disorder, and argue that none of the notions of disorder proposed so far offers a succ…Read more
  • Taking Responsibility for Responsibility
    Public Health Ethics 12 (2): 103-113. 2019.
    Governments, physicians, media and academics have all called for individuals to bear responsibility for their own health. In this article, I argue that requiring those with adverse health outcomes to bear responsibility for these outcomes is a bad basis for policy. The available evidence strongly suggests that the capacities for responsible choice, and the circumstances in which these capacities are exercised, are distributed alongside the kinds of goods we usually talk about in discussing distr…Read more
  • Modal logic without contraction in a metatheory without contraction
    Patrick Girard and Zach Weber
    Review of Symbolic Logic 12 (4): 685-701. 2019.
    Standard reasoning about Kripke semantics for modal logic is almost always based on a background framework of classical logic. Can proofs for familiar definability theorems be carried out using a nonclassical substructural logic as the metatheory? This article presents a semantics for positive substructural modal logic and studies the connection between frame conditions and formulas, via definability theorems. The novelty is that all the proofs are carried out with a noncontractive logic in the …Read more
  • Against dispositionalism: belief in cognitive science
    Philosophical Studies 175 (9): 2353-2372. 2018.
    Dispositionalism about belief has had a recent resurgence. In this paper we critically evaluate a popular dispositionalist program pursued by Eric Schwitzgebel. Then we present an alternative: a psychofunctional, representational theory of belief. This theory of belief has two main pillars: that beliefs are relations to structured mental representations, and that the relations are determined by the generalizations under which beliefs are acquired, stored, and changed. We end by describing some o…Read more
  • Academic Freedom (edited book)
    Oxford University Press. 2018.
    Recent years have seen growing concerns about threats to academic freedom in light of the changing norms of and demands on the university. This volume brings together contributions from leading philosophers about the latest issues - ranging from safe spaces to social media controversies - and traditional challenges for academic freedom.
  • Shedding Light on Keeping People in the Dark
    Topics in Cognitive Science 12 (2): 535-554. 2018.
    We want to keep hackers in the dark about our passwords and our credit card numbers. We want to keep potential eavesdroppers in the dark about our private communications with friends and business associates. This need for secrecy raises important questions in epistemology (how do we do it?) and in ethics (should we do it?). In order to answer these questions, it would be useful to have a good understanding of the concept of keeping someone in the dark. Several philosophers (e.g., Bok, 1983; Cars…Read more
  • What is Disinformation?
    Library Trends 63 (3): 401-426. 2015.
    Prototypical instances of disinformation include deceptive advertising (in business and in politics), government propaganda, doctored photographs, forged documents, fake maps, internet frauds, fake websites, and manipulated Wikipedia entries. Disinformation can cause significant harm if people are misled by it. In order to address this critical threat to information quality, we first need to understand exactly what disinformation is. This paper surveys the various analyses of this concept that h…Read more
