    Some Good and Bad News for Ethical Intuitionism
    Philosophical Quarterly 58 (232). 2008.
    The core doctrine of ethical intuitionism is that some of our ethical knowledge is non-inferential. Against this, Sturgeon has recently objected that if ethical intuitionists accept a certain plausible rationale for the autonomy of ethics, then their foundationalism commits them to an implausible epistemology outside ethics. I show that irrespective of whether ethical intuitionists take non-inferential ethical knowledge to be a priori or a posteriori, their commitment to the autonomy of ethics a…Read more

    Doubts about Moral Perception
    In Anna Bergqvist & Robert Cowan (eds.), Evaluative Perception, Oxford University Press. pp. 109-28. 2018.
    This paper defends doubts about the existence of genuine moral perception, understood as the claim that at least some moral properties figure in the contents of perceptual experience. Standard examples of moral perception are better explained as transitions in thought whose degree of psychological immediacy varies with how readily non-moral perceptual inputs, jointly with the subject's background moral beliefs, training, and habituation, trigger the kinds of phenomenological responses that moral…Read more

    In addition to thin concepts like the good, the bad and the ugly, our evaluative thought and talk appeals to thick concepts like the lewd and the rude, the selfish and the cruel, the courageous and the kind -- concepts that somehow combine evaluation and non-evaluative description. Thick concepts are almost universally assumed to be inherently evaluative in content, and many philosophers claimed them to have deep and distinctive significance in ethics and metaethics. In this first book-length tr…Read more

    Normative Appeals to the Natural
    Philosophy and Phenomenological Research 79 (2). 2009.
    Surprisingly, many ethical realists and anti-realists, naturalists and not, all accept some version of the following normative appeal to the natural (NAN): evaluative and normative facts hold solely in virtue of natural facts, where their naturalness is part of what fits them for the job. This paper argues not that NAN is false but that NAN has no adequate non-parochial justification (a justification that relies only on premises which can be accepted by more or less everyone who accepts NAN) to …Read more
  • Ruling Reasons: A Defense of Moral Generalism
    Dissertation, Cornell University. 2002.
    Moral particularism denies that moral reasons present in particular cases depend on any suitable provision of moral principles. If they did, there should be invariable reasons. But reasons are holistic: whether a consideration is a reason may vary with the context. This work responds to particularism with a moderate form of generalism, according to which it is compatible with reasons holism that moral reasons are fundamentally determined by moral principles. The holism of reasons is explained by…Read more

    Thick Ethical Concepts
    Stanford Encyclopedia of Philosophy. 2016.
    [First published 09/2016; substantive revision 02/2021.] Evaluative terms and concepts are often divided into “thin” and “thick”. We don’t evaluate actions and persons merely as good or bad, or right or wrong, but also as kind, courageous, tactful, selfish, boorish, and cruel. The latter evaluative concepts are "descriptively thick": their application somehow involves both evaluation and a substantial amount of non-evaluative description. This article surveys various attempts to answer four fund…Read more

    Thick Concepts and Variability
    Philosophers' Imprint 11 1-17. 2011.
    Some philosophers hold that so-called "thick" terms and concepts in ethics (such as 'cruel,' 'selfish,' 'courageous,' and 'generous') are contextually variable with respect to the valence (positive or negative) of the evaluations that they may be used to convey. Some of these philosophers use this variability claim to argue that thick terms and concepts are not inherently evaluative in meaning; rather their use conveys evaluations as a broadly pragmatic matter. I argue that one sort of putative …Read more

    Ethical theories and moral guidance
    Utilitas 18 (3): 291-309. 2006.
    Let the Guidance Constraint be the following norm for evaluating ethical theories: Other things being at least roughly equal, ethical theories are better to the extent that they provide adequate moral guidance. I offer an account of why ethical theories are subject to the Guidance Constraint, if indeed they are. We can explain central facts about adequate moral guidance, and their relevance to ethical theory, by appealing to certain forms of autonomy and fairness. This explanation is better than…Read more

    The Supervenience Challenge to Non-Naturalism
    In Tristram Colin McPherson & David Plunkett (eds.), The Routledge Handbook of Metaethics, Routledge. pp. 170-84. 2017.
    This paper is a survey of the supervenience challenge to non-naturalist moral realism. I formulate a version of the challenge, consider the most promising non-naturalist replies to it, and suggest that no fully effective reply has yet been given.

    Objectionable thick concepts in denials
    Philosophical Perspectives 23 (1): 439-469. 2009.
    So-called "thick" moral concepts are distinctive in that they somehow "hold together" evaluation and description. But how? This paper argues against the standard view that the evaluations which thick concepts may be used to convey belong to sense or semantic content. That view cannot explain linguistic data concerning how thick concepts behave in a distinctive type of disagreements and denials which arise when one speaker regards another's thick concept as "objectionable" in a certain sense. The…Read more

    Shapelessness in Context
    Noûs 48 (3): 573-593. 2012.
    Many philosophers believe that the extensions of evaluative terms and concepts aren’t unified under non-evaluative similarity relations and that this “shapelessness thesis” (ST) has significant metaethical implications regarding non-cognitivism, ethical naturalism, moral particularism, thick concepts and more. ST is typically offered as an explanation of why evaluative classifications appear to “outrun” classifications specifiable in independently intelligible non-evaluative terms. This paper ar…Read more
