    Plural harm: plural problems
    Philosophical Studies 180 (2): 553-565. 2023.
    The counterfactual comparative account of harm faces problems in cases that involve overdetermination and preemption. An influential strategy for dealing with these problems, drawing on a suggestion made by Derek Parfit, is to appeal to _plural harm_—several events _together_ harming someone. We argue that the most well-known version of this strategy, due to Neil Feit, as well as Magnus Jedenheim Edling’s more recent version, is fatally flawed. We also present some general reasons for doubting t…Read more

    Vagueness, Incomparability, and the Collapsing Principle
    Ethical Theory and Moral Practice 16 (3): 449-463. 2013.
    John Broome has argued that incomparability and vagueness cannot coexist in a given betterness order. His argument essentially hinges on an assumption he calls the ‘collapsing principle’. In an earlier article I criticized this principle, but Broome has recently expressed doubts about the cogency of my criticism. Moreover, Cristian Constantinescu has defended Broome’s view from my objection. In this paper, I present further arguments against the collapsing principle, and try to show that Constan…Read more

    Parity demystified
    Theoria 76 (2): 119-128. 2010.
    Ruth Chang has defended a concept of "parity", implying that two items may be evaluatively comparable even though neither item is better than or equally good as the other. This article takes no stand on whether there actually are cases of parity. Its aim is only to make the hitherto somewhat obscure notion of parity more precise, by defining it in terms of the standard value relations. Given certain plausible assumptions, the suggested definiens is shown to state a necessary and sufficient condi…Read more

    The Oughts and Cans of Objective Consequentialism
    Utilitas 11 (1): 91-96. 1999.
    Frances Howard -Snyder has argued that objective consequentialism violates the principle that ‘ought’ implies ‘can’. In most situations, she claims, we cannot produce the best consequences available, although objective consequentialism says that we ought to do so. Here I try to show that Howard -Snyder's argument is unsound. The claim that we typically cannot produce the best consequences available is doubtful. And even if there is a sense of ‘producing the best consequences’ in which we cannot …Read more

    Broome's argument against value incomparability
    Utilitas 16 (2): 220-224. 2004.
    John Broome has argued that alleged cases of value incomparability are really examples of vagueness in the betterness relation. The main premiss of his argument is ‘the collapsing principle’. I argue that this principle is dubious, and that Broome's argument is therefore unconvincing. Correspondence:c1 [email protected].

    Counterexamples to Principle Beta: A Response to Crisp and Warfield
    Philosophy and Phenomenological Research 66 (3): 730-737. 2003.
    The well‐known “Consequence Argument” for the incompatibility of freedom and determinism relies on a certain rule of inference; “Principle Beta”. Thomas Crisp and Ted Warfield have recently argued that all hitherto suggested counterexamples to Beta can be easily circumvented by proponents of the Consequence Argument. I present a new counterexample which, I argue, is free from the flaws Crisp and Warfield detect in earlier examples.

    In Section 1, I rehearse some arguments for the claim that morality should be ``action-guiding'', and try to state the conditions under which a moral theory is in fact action-guiding. I conclude that only agents who are cognitively and conatively ``ideal'' are in general able to use a moral theory as a guide to action. In Sections 2 and 3, I discuss whether moral ``actualism'' implies that morality cannot be action-guiding even for ideal agents. If actualism is true, an ideal agent will know abo…Read more

    Aggregating Harms - Should We Kill to Avoid Headaches?
    Theoria 66 (3): 246-255. 2000.
    It is plausible to claim that it is morally worse to kill an innocent person than to give any number of people a mild one‐hour headache. Alaistar Norcross has argued that consequentialists, at least, should reject this claim. According to him, any harm that can befall a person can be morally outweighed by a sufficient number of very small harms. He gives a general argument for this view, and tries to show, by means of an argument from analogy, that it is less counter‐intuitive than it appears. I…Read more

    Mere Addition and Two Trilemmas of Population Ethics
    Economics and Philosophy 14 (2): 283. 1998.
    A principal aim of the branch of ethics called ‘population theory’ or ‘population ethics’ is to find a plausible welfarist axiology, capable of comparing total outcomes with respect to value. This has proved an exceedingly difficult task. In this paper I shall state and discuss two ‘trilemmas’, or choices between three unappealing alternatives, which the population ethicist must face. The first trilemma is not new. It originates with Derek Parfit's well-known ‘Mere Addition Paradox’, and was fir…Read more

    Consequentialism, Distribution and Desert
    Utilitas 9 (3): 307. 1997.
    This paper criticizes the consequentialist theory recently put forward by Fred Feldman. I argue that this theory violates two crucial requirements. Another theory, proposed by Peter Vallentyne, is similarly flawed. Feldman's basic ideas could, however, be developed into a more plausible theory. I suggest one possible way of doing this

    Well-Being Counterfactualist Accounts of Harm and Benefit
    Australasian Journal of Philosophy 99 (1): 164-174. 2021.
    ABSTRACT Suppose that, for every possible event and person who would exist whether or not the event were to occur, there is a well-being level that the person would occupy if the event were to occur, and a well-being level that the person would occupy if the event were not to occur. Do facts about such connections between events and well-being levels always suffice to determine whether an event would harm or benefit a person? Many seemingly attractive accounts of harm and benefit entail an affir…Read more

    Higher Values and Non-Archimedean Additivity
    Theoria 73 (1): 3-27. 2007.
    Many philosophers have claimed that extensive or additive measurement is incompatible with the existence of "higher values", any amount of which is better than any amount of some other value. In this paper, it is shown that higher values can be incorporated in a non-standard model of extensive measurement, with values represented by sets of ordered pairs of real numbers, rather than by single reals. The suggested model is mathematically fairly simple, and it applies to structures including negat…Read more

    Organic unities, non-trade-off, and the additivity of intrinsic value
    The Journal of Ethics 5 (4): 335-360. 2001.
    Whether or not intrinsic value is additively measurable is often thought to depend on the truth or falsity of G. E. Moore's principle of organic unities. I argue that the truth of this principle is, contrary to received opinion, compatible with additive measurement. However, there are other very plausible evaluative claims that are more difficult to combine with the additivity of intrinsic value. A plausible theory of the good should allow that there are certain kinds of states of affairs whose …Read more

    The presumption of nothingness
    Ratio 14 (3). 2001.
    Several distinguished philosophers have argued that since the state of affairs where nothing exists is the simplest and least arbitrary of all cosmological possibilities, we have reason to be surprised that there is in fact a non-empty universe. We review this traditional argument, and defend it against two recent criticisms put forward by Peter van Inwagen and Derek Parfit. Finally, we argue that the traditional argument nevertheless needs reformulation, and that the cogency of the reformulated…Read more

    Causal Accounts of Harming
    Pacific Philosophical Quarterly 103 (2): 420-445. 2021.
    A popular view of harming is the causal account (CA), on which harming is causing harm. CA has several attractive features. In particular, it appears well equipped to deal with the most important problems for its main competitor, the counterfactual comparative account (CCA). However, we argue that, despite its advantages, CA is ultimately an unacceptable theory of harming. Indeed, while CA avoids several counterexamples to CCA, it is vulnerable to close variants of some of the problems that bese…Read more

    More Problems for the Counterfactual Comparative Account of Harm and Benefit
    Ethical Theory and Moral Practice 22 (4): 795-807. 2018.
    The counterfactual comparative account of harm and benefit has several virtues, but it also faces serious problems. I argue that CCA is incompatible with the prudential and moral relevance of harm and benefit. Some possible ways to revise or restrict CCA, in order to avoid this conclusion, are discussed and found wanting. Finally, I try to show that appealing to the context-sensitivity of counterfactuals, or to the alleged contrastive nature of harm and benefit, does not provide a solution.

    Well-Being without Being? A Reply to Feit
    Utilitas 30 (2): 198-208. 2018.
    In a recent Utilitas article, Neil Feit argues that every person occupies a well-being level of zero at all times and possible worlds at which she fails to exist. Views like his face the problem of the subject': how can someone have a well-being level in a scenario where she lacks intrinsic properties? Feit argues that this problem can be solved by noting, among other things, that a proposition about a person can be true at a possible world in which neither she nor the proposition exists. In thi…Read more

    The small-improvement argument rescued
    Philosophical Quarterly 61 (242): 171-174. 2011.
    Gustafsson and Espinoza have recently argued that the ‘small-improvement argument’, against completeness as a rationality requirement for preference orderings, is defective. They claim that the two main premises of the argument conflict, and hence should not both be accepted. I show that this conflict can be avoided by modifying one of the premises

    Is Our Existence in Need of Further Explanation?
    Inquiry: An Interdisciplinary Journal of Philosophy 41 (3): 255-275. 1998.
    Several philosophers have argued that our cosmos is either purposely created by some rational being, or else just one among a vast number of actually existing cosmoi. According to John Leslie and Peter van Inwagen, the existence of a cosmos containing rational beings is analogous to drawing the winning straw among millions of straws. The best explanation in the latter case, they maintain, is that the drawing was either rigged by someone, or else many such lotteries have taken place. Arnold Zubof…Read more
