    Parsimony and the Argument from Queerness
    Res Philosophica 91 (4): 609-627. 2014.
    In his recent book Error Theory: History, Critique, Defence, Jonas Olson attempts to revive the argument from queerness originally made famous by J.L. Mackie. In this paper, we do three things. First, we eliminate four untenable formulations of the argument. Second, we argue that the most plausible formulation is one that depends crucially upon considerations of parsimony. Finally, we evaluate this formulation of the argument. We conclude that it is unproblematic for proponents of moral non-natu…Read more

    On Believing the Error Theory
    with Alexander Hyun
    Journal of Philosophy 111 (11): 631-640. 2014.
    In his recent article entitled ‘Can We Believe the Error Theory?’ Bart Streumer argues that it is impossible (for anyone, anywhere) to believe the error theory. This might sound like a problem for the error theory, but Streumer argues that it is not. He argues that the un-believability of the error theory offers a way for error theorists to respond to several objections commonly made against the view. In this paper, we respond to Streumer’s arguments. In particular, in sections 2-4, we offer sev…Read more

    The Self-Undermining Arguments from Disagreement
    Oxford Studies in Metaethics 14 23-46. forthcoming.
    Arguments from disagreement against non-skeptical moral realism begin by noticing (or supposing) widespread, fundamental moral disagreement among a certain group of people (e.g., the folk, moral philosophers, idealized agents). Then, some skeptical or anti-realist-friendly conclusion is drawn. I argue that arguments from disagreement share a structure that makes them vulnerable to a single, powerful objection: they self-undermine. For each formulation of the argument from disagreement, at least …Read more

    Against Scanlon's Theory of the Strength of Practical Reasons
    Journal of Ethics and Social Philosophy (3): 1-6. 2015.
    We often say that one reason is stronger, or weightier, than another. These are metaphors. What does normative strength or weight really consist in? Scanlon (2014) offers a novel answer to this question. His answer appeals to counterfactuals of various kinds. I argue that appealing to counterfactuals leads to deep problems for his view.

    We provide a novel defense of the possibility of level-splitting beliefs and uses this defense to show that the steadfast response to peer disagreement is not, as it is often claimed to be, unnecessarily dogmatic. To provide this defense, a neglected form of moral disagreement is analysed. Within the context of this particular kind of moral disagreement, a similarly neglected form of level-splitting belief is identified and then defended from critics of the rationality of level-splitting beliefs…Read more
