    There is a tension inherent in the ways in which promises feature in our ethical thought. On the one hand, that one is obligated to keep one's promises appears to be one of the most straightforward, unquestionable moral truths around. On the other hand, promissory obligation, as an obligation voluntarily incurred through a performative speech act, has appeared to many as mysterious, and thus in need of a specific explanation. This book sets out from this tension to substantially advance debates …Read more

    One classic objection to Objectivism about ought is that it recommends unconscionably risky actions in so-called Three-Option-Cases, the most famous of which is Jackson's case featuring a doctor called Jill. Some philosophers deny this orthodoxy and claim that Objectivism can yet account for our intuitions in such cases. In this paper, I critically evaluate such attempts and draw some more general lessons about Objectivism's ability to deal with risk and recklessness. I argue that an adequate fo…Read more

    Perspectivism and Rights
    Journal of Ethics and Social Philosophy 30 (3): 437-473. 2025.
    Perspectivism is the view that what an agent ought to do always needs to be determined relative to this agent’s epistemic position. Despite its many virtues, this theory appears crucially flawed in its inability to properly account for the existence of universal claim rights. This article draws out this incompatibility through a set of plausible and widely accepted conceptual claims. It then discusses options available to the perspectivist in reaction to this problem. A wholesale denial of unive…Read more

    Must We Worry About Epistemic Shirkers?
    Inquiry: An Interdisciplinary Journal of Philosophy 68 (10): 4099-4124. 2024.
    It is commonly assumed that blameworthiness is epistemically constrained. If one lacks sufficient epistemic access to the fact that some action harms another, then one cannot be blamed for harming. Acceptance of an epistemic condition for blameworthiness can give rise to a worry, however: could agents ever successfully evade blameworthiness by deliberately stunting their epistemic position? I discuss a particularly worrisome version of such epistemic shirking, in which agents pre-emptively seek …Read more

    Being Fully Excused for Wrongdoing
    Pacific Philosophical Quarterly 104 324-347. 2022.
    On the classical understanding, an agent is fully excused for an action if and only if performing this action was a case of faultless wrongdoing. A major motivation for this view is the apparent existence of paradigmatic types of excusing considerations, affecting fault but not wrongness. I show that three such considerations, ignorance, duress and compulsion, can be shown to have direct bearing on the permissibility of actions. The appeal to distinctly identifiable excusing considerations thus …Read more

    Value-based accounts of normative powers and the wishful thinking objection
    Philosophical Studies 179 (11): 3211-3231. 2022.
    Normative powers like promising allow agents to effect changes to their reasons, permissions and rights by the means of communicative actions whose function is to effect just those changes. An attractive view of the normativity of such powers combines a non-reductive account of their bindingness with a value-based grounding story of why we have them. This value-based view of normative powers however invites a charge of wishful thinking: Is it not bad reasoning to think that we have a given power…Read more

    Trust-Based Theories of Promising
    Philosophical Quarterly 70 (280): 443-463. 2020.
    This paper discusses the prospects of a comprehensive philosophical account of promising that relies centrally on the notion of trust. I lay out the core idea behind the Trust View, showing how it convincingly explains the normative contours and the unique value of our promissory practice. I then sketch three distinct options of how the Trust View can explain the normativity of promises. First, an effect based-view, second, a view drawing on a wider norm demanding respect to those whom one has i…Read more

    Error Theory, Unbelievability and the Normative Objection
    Journal of Ethics and Social Philosophy 17 (2): 219-227. 2020.
    One of the most formidable challenges to the Error Theory is the Normative Objection, according to which the Error Theory ought to be rejected because of its deeply implausible first-order normative implications. Recently, Bart Streumer has offered a novel and powerful defence of the Error Theory against this objection. Streumer argues that the Error Theory’s plausibility deficit when viewed against the background of our normative beliefs does not show the theory’s falsity. Rather, it can be exp…Read more
