    Haybron on Mood Propensity and Happiness
    Journal of Happiness Studies 10. 2009.
    Daniel Haybron has made an original contribution to philosophical discussions of happiness. He has put forward a theory that identifies happiness with moods and the propensity to experience moods. Haybron’s contribution deserves a critical examination. The first section of my paper is interpretive. I show how Haybron uses the concepts of ‘central affective states’ and ‘mood propensity’ to define happiness. The second and third sections of the paper are critical. They focus on the inclusion of mo…Read more

    Animals Deserve Moral Consideration
    Journal of Agricultural and Environmental Ethics 33 (2): 177-185. 2020.
    Timothy Hsiao asks a good question: Why believe animals deserve moral consideration? His answer is that we should not. He considers various other answers and finds them wanting. In this paper I consider an answer Hsiao has not yet discussed: We should accept a conservative view about how to form beliefs. And such a view will instruct us to believe that animals deserve moral consideration. I think conservatives like Hsiao do best to answer his question in a way that upholds the moral status of an…Read more

    What Are the Odds that Everyone is Depraved?
    American Philosophical Quarterly 57 (3): 299-308. 2020.
    Why does God allow evil? One hypothesis is that God desires the existence and activity of free creatures but He was unable to create a world with such creatures and such activity without also allowing evil. If Molinism is true, what probability should be assigned to this hypothesis? Some philosophers claim that a low probability should be assigned because there are an infinite number of possible people and because we have no reason to suppose that such creatures will choose one way rather than a…Read more

    Aquinas and Gregory the Great on the Puzzle of Petitionary Prayer
    Ergo: An Open Access Journal of Philosophy 5. 2018.
    I defend a solution to the puzzle of petitionary prayer based on some ideas of Aquinas, Gregory the Great, and contemporary desert theorists. I then address a series of objections. Along the way broader issues about the nature of desert, what is required for an action to have a point, and what is required for a puzzle to have a solution are discussed.

    Good News for the Logical Autonomy of Ethics
    Argumentation 23 (2): 277-283. 2009.
    Toomas Karmo claims that his taxonomy of ethical sentences has the result that there does not exist a sound argument with all non-ethical premises and an ethical conclusion. In a recent paper, Mark T. Nelson argues against this claim. Nelson presents a sound argument that he takes to be such that (i) Karmo’s taxonomy classifies that argument’s single premise as non-ethical and (ii) Karmo’s taxonomy classifies that argument’s conclusion as ethical. I attempt to show that Nelson is mistaken about …Read more

    Murdering an Accident Victim: A New Objection to the Bare-Difference Argument
    Australasian Journal of Philosophy 96 (4): 767-778. 2018.
    Many philosophers, psychologists, and medical practitioners believe that killing is no worse than letting die on the basis of James Rachels's Bare-Difference Argument. I show that his argument is unsound. In particular, a premise of the argument is that his examples are as similar as is consistent with one being a case of killing and the other being a case of letting die. However, the subject who lets die has both the ability to kill and the ability to let die while the subject who kills lacks t…Read more

    ‘Is’–‘Ought’ Derivations and Ethical Taxonomies
    Philosophia 36 (4): 545-566. 2008.
    Hume seems to claim that there does not exist a valid argument that has all non-ethical sentences as premises and an ethical sentence as its conclusion. Starting with Prior, a number of counterexamples to this claim have been proposed. Unfortunately, all of these proposals are controversial. Even the most plausible have a premise that seems like it might be an ethical sentence or a conclusion that seems like it might be non-ethical. Since it is difficult to tell whether any of these counterexamp…Read more

    An Adamsian Theory of Intrinsic Value
    Ethical Theory and Moral Practice 14 (3): 273-289. 2011.
    In this paper I develop a theological account of intrinsic value drawn from some passages in Robert Merrihew Adams’ book Finite and Infinite Goods. First I explain why Adams’ work on this topic is interesting, situate his theory within the broader literature on intrinsic value, and draw attention to some of its revisionist features. Next I state the theory, raise some problems for it, and refine it in light of those problems. Then I illustrate how the refined theory works by showing that it has …Read more

    Richard Joyce's new objections to the divine command theory
    Journal of Religious Ethics 38 (1): 189-196. 2010.
    In a 2002 paper for this journal, Richard Joyce presents three new arguments against the Divine Command Theory. In this comment, I attempt to show that each of these arguments is either unpersuasive or uninteresting. Two of Joyce’s arguments are unpersuasive because they rely on an implausible principle or an implausible claim about what counts as a platitude governing use of the term “wrong.” Joyce’s other argument is uninteresting because it is persuasive only if Joyce’s formulation of the Eut…Read more

    From Isolation to Skepticism
    Erkenntnis 81 (3): 649-668. 2016.
    If moral properties lacked causal powers, would moral skepticism be true? I argue that it would. Along the way I respond to various arguments that it would not.

    Giving up omnipotence
    Canadian Journal of Philosophy 44 (1): 97-117. 2014.
    For any essential property God has, there is an ability He does not have. He is unable to bring about any state of affairs in which He does not have that property. Such inabilities seem to preclude omnipotence. After making trouble for the standard responses to this problem, I offer my own solution: God is not omnipotent. This may seem like a significant loss for the theist. But I show that it is not. The theist may abandon the doctrine that God is omnipotent without scaling back the extent of H…Read more
