    Moral Testimony Goes Only So Far
    In David Shoemaker (ed.), Oxford Studies in Agency and Responsibility Volume 6, Oxford University Press. pp. 165-185. 2019.
    This paper argues for answers to two questions, and then identifies a tension between the two answers. First, regarding the implications of moral ignorance for moral responsibility: “Do false moral views exculpate?” Does believing that one is acting morally permissibly render one blameless? It does not. Second, in moral epistemology: “Can moral testimony provide moral knowledge?” It can (even granting some worries about moral deference). The tension: If moral testimony can provide moral knowledg…Read more

    The Ever Conscious View and the Contingency of Moral Status
    In Steve Clarke, Hazem Zohny & Julian Savulescu (eds.), Rethinking Moral Status, Oxford University Press. pp. 90-107. 2021.
    It is common to think that if something has moral status, then, necessarily, it has moral status. This chapter argues for a view of moral status, the Ever Conscious View, which holds that a living being has moral status throughout its life just in case it is ever conscious, at any point in its life. Moral status is contingent: some beings that have moral status might have lacked moral status, and some beings that lack moral status might have had moral status. The author explains and addresses th…Read more

    Morality Within the Realm of the Morally Permissible
    In Mark Timmons (ed.), Oxford Studies in Normative Ethics: Volume 5, Oxford University Press Uk. pp. 221-244. 2015.
    This chapter claims standard conceptions of moral theory tend to be too narrow because they fail to recognize a full range of morally significant distinctions within the category of the morally permissible—distinctions that do not merely follow from a theory’s account of the morally required. The more particular claim of the chapter is that moral theory should recognize the category of morally permissible moral mistakes, characterized as an action which, although it is morally permissible (and t…Read more

    The Irrelevance of Moral Uncertainty
    In Russ Shafer-Landau (ed.), Oxford Studies in Metaethics: Volume 10, Oxford University Press Uk. pp. 53-79. 2015.
    Suppose you believe you’re morally required to φ but that it’s not a big deal; and yet you think it _might_ be deeply morally wrong to φ. You are in a state of moral uncertainty, holding high credence in one moral view of your situation, while having a small credence in a radically opposing moral view. A natural thought is that in such a case you should not φ, because φ ing would be too morally risky. The author argues that this natural thought is misguided. If φ ing is in fact morally required,…Read more

    Abortion and the Non-Identity Problem
    In Jeff McMahan, Timothy Campbell, Ketan Ramakrishnan & Jimmy Goodrich (eds.), Ethics and Existence: The Legacy of Derek Parfit, Oxford University Press. 2022.
    How is the ethics of abortion related to the non-identity problem? Some cases of deciding whether to abort turn out to raise the non-identity problem: for the same reasons that it is morally required to wait to conceive in some temporary condition non-identity cases, it is also morally required to abort some pregnancies. This implies that the following surprising claim is true: sometimes it is morally required to kill a being for its own sake, although continuing to live would be better for …Read more

    Ethics is Hard! What Follows?
    In Dana Kay Nelkin & Derk Pereboom (eds.), Oxford Handbook of Moral Responsibility, Oxford University Press. 2022.
    When someone acts morally wrongly because they are caught in the grip of a false moral view, although they have thought a reasonable amount about morality, are they thereby blameless for so acting? Recently, a number of philosophers have embraced the view that moral ignorance does exculpate in such cases. This paper outlines an attractive line of thought according to which moral ignorance exculpates. This line of thought is mistaken: being caught in the grip of a false moral view is not excu…Read more

    "I'll be glad I did it" reasoning and the significance of future desires
    In John Hawthorne (ed.), Ethics, Wiley Periodicals. pp. 177-199. 2004.
    We use “I’ll be glad I did it” reasoning all the time. For example, last night I was trying to decide whether to work on this paper or go out to a movie. I realized that if I worked on the paper, then today I would be glad I did it. Whereas, if I went out to the movie, today I would regret it. This enabled me to see that I should work on the paper rather than going out to a movie. This looks like excellent reasoning: Paper argument: 1. If I work on my paper, I’ll be glad I did it. 2. Therefore, …Read more

    There is No Moral Ought and No Prudential Ought
    In Ruth Chang & Kurt Sylvan (eds.), The Routledge Handbook of Practical Reason, Routledge. pp. 438-456. 2020.
    It may seem that there are a number of different _oughts_. There is a moral _ought_, there is a prudential _ought_, etc. Furthermore, it may seem that each _ought_ is such that one ought to do the best thing one could do, where the sense of best at issue varies with the kind of _ought_ it is. Thus, it seems that morally, a person ought to do the morally best thing she could do; and prudentially, a person ought to do the prudentially best thing she could do. This suggests that the moral _ough…Read more

    The Moral Significance of Animal Pain and Animal Death
    In Beauchamp Tom & R. G. Frey (eds.), The Oxford Handbook of Animal Ethics, Oxford University Press. pp. 726-737. 2011.
    This article addresses the question: “What follows from the claim that we have a certain kind of strong reason against animal cruelty?” It deals with the ethics of killing animals. It finds the following common assumption highly puzzling and problematic: despite our obligations not to commit animal cruelty, there is no comparably strong reason against painlessly killing animals in the prime of life. It argues that anyone who accepts this view is committed to the moral position that either we hav…Read more

    Eating Meat as a Morally Permissible Mistake
    In Andrew Chignell, Terence Cuneo & Matthew C. Halteman (eds.), Philosophy Comes to Dinner: Arguments on the Ethics of Eating, Routledge. pp. 215-231. 2016.
    Many people who are vegetarians for moral reasons nevertheless accommodate the buying and eating of meat in many ways. They go to certain restaurants in deference to their friends’ meat eating preferences; they split restaurant checks, subsidizing the purchase of meat; and they allow money they share with their spouses to be spent on meat. This behavior is puzzling. If someone is a moral vegetarian—that is, a vegetarian for moral reasons—then it seems that the person must believe that buying …Read more

    Transformative Experiences and Reliance on Moral Testimony
    Res Philosophica 92 (2): 323-339. 2015.
    Some experiences are transformative in that it is impossible to imagine experiencing them until one experiences them. It has been argued that pregnancy and parenthood are like that, and that therefore one cannot make a rational decision whether to become a mother. I argue that pregnancy and parenthood are not like that; but that if even if they are, a woman can still make a rational decision by relying on testimony about the value of these experiences. I then discuss an objection that such testi…Read more

    Fischer and Lamenting Nonexistence
    Social Theory and Practice 37 (1): 129-142. 2011.
    Why do we wish to die later but do not wish to have been created earlier? There is no puzzle here. It is false that if we had been created earlier we would have lived longer lives. Why don’t we wish to have been created earlier but with our actual times of death? That wish simply is not mandated by the more general wish to have lived a longer life. Furthermore, one might prefer one’s actual life to the better, but considerably different, life one would have lived at an earlier time

    Harming as causing harm
    In David Wasserman & Melinda Roberts (eds.), Harming Future Persons: Ethics, Genetics and the Nonidentity Problem, Springer. pp. 137--154. 2009.
    This paper argues that non-identity actions are wrong because they _cause_ harm to people. While non-identity actions also typically benefit people, failure to act would similarly benefit someone, so considerations of benefit are ineligible to justify the harm. However, in some non-identity cases, failure to act would not benefit anyone: cases where one is choosing whether to procreate at all. These are the _hard_ non-identity cases. Not all "different-number" cases are hard. In some cases…Read more

    It seems that if abortion is permissible, then stem cell research must be as well: it involves the death of a less significant thing (an embryo rather than a fetus) for a greater good (lives saved rather than nine months of physical imposition avoided). However, I argue in this essay that this natural thought is mistaken. In particular, on the assumption that embryos and fetuses have the full moral status of persons, abortion is permissible but one form of stem cell research is notFthe practice o…Read more

    The potentiality problem
    Philosophical Studies 114 (1-2). 2003.
    Many people face a problem about potentiality: their moral beliefs appear to dictate inconsistent views about the significance of the potentiality to become a healthy adult. Briefly, the problem arises as follows. Consider the following two claims. First, both human babies and cats have moral status, but harms to babies matter more, morally, than similar harms to cats. Second, early human embryos lack moral status. It appears that the first claim can only be true if human babies have more moral sta…Read more

    Part One addresses the question whether the fact that some persons love something, worship it, or deeply care about it, can endow moral status on that thing. I argue that the answer is “no.” While some cases lend great plausibility to the view that love or worship can endow moral status, there are other cases in which love or worship clearly fails to endow moral status. Furthermore, there is no principled way to distinguish these two types of cases, so we must conclude that love or worship never…Read more

    Morally Permissible Moral Mistakes
    Ethics 126 (2): 366-393. 2016.
    Does it ever happen that there are things we shouldn’t do and the reasons we shouldn’t do them are moral reasons, yet doing them is not morally wrong? Surprisingly, yes. I argue for a category that has not been recognized by moral theorists: morally permissible moral mistakes. Sometimes a supererogatory action is the thing a person should do; in failing to act, one makes a morally permissible moral mistake. Recognizing the category of morally permissible moral mistakes solves a puzzle about supe…Read more
  • Moral Status
    Dissertation, Massachusetts Institute of Technology. 2003.
    Chapters One through Three present the following view: I explain moral status as follows: something has moral status just in case we have, reasons not to cause harms to it simply in virtue of the badness of the harms for it. Moral status is not a matter of degree. A living thing has moral status just in case it is ever conscious. If something has moral status, then the strength of a moral reason not to harm it is proportional to the severity of the harm. ;In this view, all humans and animals tha…Read more
