    Revisiting the Tropic of Value: Reply to Rabinowicz and Rønnow‐Rasmussen
    Philosophy and Phenomenological Research 67 (2): 412-422. 2003.
    In this paper, I defend the view that the values of concrete objects and persons are reducible to the final values of tropes. This reductive account has recently been discussed and rejected by Rabinowicz and R0nnow‐Rasmussen (2003). I begin by explaining why the reduction is appealing in the first place. In my rejoinder to Rabinowicz and R0nnow‐Rasmussen I defend trope‐value reductionism against three challenges. 1 focus mainly on their central objection, that holds that the reduction is untenab…Read more

    This article is a response to critical articles by Daan Evers, Bart Streumer, and Teemu Toppinen on my book Moral Error Theory: History, Critique, Defence. I will be concerned with four main topics. I shall first try to illuminate the claim that moral facts are queer, and its role in the argument for moral error theory. In section 2, I discuss the relative merits of moral error theory and moral contextualism. In section 3, I explain why I still find the queerness argument concerning supervenienc…Read more

    Error Theory in Metaethics
    In Tristram Colin McPherson & David Plunkett (eds.), The Routledge Handbook of Metaethics, Routledge. pp. 58-71. 2017.
    Error theories have been proposed and defended in several different areas of philosophy. In addition to ethics, there are error theories about numbers, color, free will, and personal identity. Moral error theories differ in scope. Theories at one end of the spectrum take normative judgments in general—of which moral judgments are a subclass—to be uniformly false, whereas theories at the other end of the spectrum take only a subclass of moral judgments—example those concerning duty and obligation…Read more

    Moral Error: History, Critique, Defence
    Oxford University Press UK. 2017.
    Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

    Brentano and the Buck-Passers
    with Sven Danielsson
    Mind 116 (463). 2007.
    According to T. M. Scanlon's 'buck-passing' analysis of value, x is good means that x has properties that provide reasons to take up positive attitudes vis-à-vis x. Some authors have claimed that this idea can be traced back to Franz Brentano, who said in 1889 that the judgement that x is good is the judgement that a positive attitude to x is correct ('richtig'). The most discussed problem in the recent literature on buckpassing is known as the 'wrong kind of reason' problem (the WKR problem): i…Read more

    Projectivism and Error in Hume’s Ethics
    Hume Studies 37 (1): 19-42. 2011.
    This essay argues that while Hume believes both that morality is grounded in our ordinary moral practices, sentiments, and beliefs, and that moral properties are real, he also holds that ordinary moral thinking involves systematically erroneous beliefs about moral properties. These claims, on their face, seem difficult to square with one another but this paper argues that on Hume’s view, they are reconcilable. The reconciliation is effected by making a distinction between Hume’s descriptive meta…Read more

    Cognitivism is the view that the primary function of moral judgements is to express beliefs that purport to say how things are; expressivism is the contrasting view that their primary function is to express some desire-like state of mind. I shall consider what I call the freshman objection to expressivism. It is pretty uncontroversial that this objection rests on simple misunderstandings. There are nevertheless interesting metaethical lessons to learn from the fact that the freshman objection is…Read more

    Expressivism and moral certitude
    Philosophical Quarterly 59 (235): 202-215. 2009.
    Michael Smith has recently argued that non-cognitivists are unable to accommodate crucial structural features of moral belief, and in particular that non-cognitivists have trouble accounting for subjects' certitude with respect to their moral beliefs. James Lenman and Michael Ridge have independently constructed 'ecumenical' versions of non-cognitivism, intended to block this objection. We argue that these responses do not work. If ecumenical non-cognitivism, a hybrid view which incorporates bot…Read more

    Rationalism vs. Sentimentalism: Reviewing Price's Review
    Philosophical Papers 43 (3): 429-445. 2014.
    This paper revisits Richard Price’s Review of the Principal Questions in Morals. Price was a defender of rationalism about ethics and he anticipated many views and arguments that became influential as the metaethical and ethical debates evolved over the later centuries. The paper explores and assesses Price’s arguments in favour of rationalism and against sentimentalism, with a view to how they bear on the modern metaethical debate.

    Intrinsicalism and conditionalism about final value
    Ethical Theory and Moral Practice 7 (1): 31-52. 2004.
    The paper distinguishes between two rival views about the nature of final value (i.e. the value something has for its own sake) — intrinsicalism and conditionalism. The former view (which is the one adopted by G.E. Moore and several later writers) holds that the final value of any F supervenes solely on features intrinsic to F, while the latter view allows that the final value of F may supervene on features non-intrinsic to F. Conditionalism thus allows the final value of F to vary according to …Read more

    Buck-passing and the wrong kind of reasons
    Philosophical Quarterly 54 (215). 2004.
    According to T.M. Scanlon's buck-passing account of value, to be valuable is not to possess intrinsic value as a simple and unanalysable property, but rather to have other properties that provide reasons to take up an attitude in favour of their owner or against it. The 'wrong kind of reasons' objection to this view is that we may have reasons to respond for or against something without this having any bearing on its value. The challenge is to explain why such reasons are of the wrong kind. This…Read more

    The Personal and the Fitting
    Journal of Moral Philosophy 11 (3): 341-352. 2014.
    This paper is a critical notice of a recent significant contribution to the debate about fitting attitudes and value, namely Toni Rønnow-Rasmussen’s Personal Value. In this book, Rønnow-Rasmussen seeks to analyse the notion of personal value—an instance of the notion of good for a person—in terms of fitting attitudes. The paper has three main themes: Rønnow-Rasmussen’s discussion of general problems for fitting attitude analyses; his formulation of the fitting attitude analysis of personal value…Read more

    Non-Cognitivism and Fundamental Moral Certitude: Reply to Eriksson and Francén Olinder
    Australasian Journal of Philosophy 95 (4): 794-799. 2017.
    Accommodating degrees of moral certitude is a serious problem for non-cognitivism about ethics. In particular, non-cognitivism has trouble accommodating fundamental moral certitude. John Eriksson and Ragnar Francén Olinder [2016] have recently proposed a solution. In fact, Eriksson and Francén Olinder offer two different proposals—one ‘classification’ account and one ‘projectivist’ account. We argue that the classification account faces the same problem as previous accounts do, while the project…Read more

    Fitting Attitude Analyses of Value and the Partiality Challenge
    Ethical Theory and Moral Practice 12 (4): 365-378. 2009.
    According to ‘Fitting Attitude’ (FA) analyses of value, for an object to be valuable is for that object to have properties—other than its being valuable—that make it a fitting object of certain responses. In short, if an object is positively valuable it is fitting to favour it; if an object is negatively valuable it is fitting to disfavour it. There are several variants of FA analyses. Some hold that for an object to be valuable is for it to be such that it ought to be favoured; others hold that…Read more

    Are desires de dicto fetishistic?
    Inquiry: An Interdisciplinary Journal of Philosophy 45 (1). 2002.
    In The Moral Problem Michael Smith presents what he claims is a decisive argument against moral externalism. Smith's claims that (i) moral externalists are committed to explain the connection between moral beliefs and moral motivation in terms of de dicto desires, and (ii) de dicto desires to perform moral acts amounts to moral fetishism. The argument is spelled out and the difference between desires de dicto and desires de re explained. The tenability of the fetishist argument (as it has been n…Read more

    Against the Being For Account of Normative Certitude
    Journal of Ethics and Social Philosophy 6 (2): 1-8. 2012.
    Just as we can be more or less certain about empirical matters, we can be more or less certain about normative matters. Recently, it has been argued that this is a challenge for noncognitivism about normativity. Michael Smith presented the challenge in a 2002 paper and James Lenman and Michael Ridge responded independently. Andrew Sepielli has now joined the rescue operation. His basic idea is that noncognitivists should employ the notion of being for to account for normative certitude. We shall…Read more
