• A dogma of contemporary ethical theory maintains that the nature of normative support for affective attitudes is the very same as the nature of normative support for actions. The prevailing view is that normative reasons provide the support across the board. I argue that the nature of normative support for affective attitudes is importantly different from the nature of normative support for actions. Actions are indeed supported by reasons. Reasons are gradable and contributory. The support relat…Read more
  • Libertarian philosopher Michael Huemer has argued recently that there is a prima facie right to immigrate, and, moreover, that concerns people have about the effects of immigration are not strong enough to neutralize or override this prima facie right. In this paper, I focus on one particular concern that Huemer deems insufficiently strong to neutralize or override the prima facie right to immigrate, namely, the concern that unrestricted immigration poses a threat to one’s culture. I argue that …Read more
  • Doing Moral Philosophy Without ‘Normativity’
    Journal of the American Philosophical Association 1-19. forthcoming.
    This essay challenges widespread talk about morality's ‘normativity’. My principal target is not any specific claim or thesis in the burgeoning literature on ‘normativity’, however. Rather, I aim to discourage the use of the word among moral philosophers altogether and to reject a claim to intradisciplinary authority that is both reflected in and reinforced by the role the word has come to play in the discipline. My hope is to persuade other philosophers who, like me, persist in being interested…Read more
  • The metaphysical equivalence between 3D and 4D theories of species
    Revista Portuguesa de Filosofia 71 (4): 781-806. 2015.
    Resumo Neste artigo, vamos considerar o recente debate na metafísica da evolução, no que diz respeito tanto à persistência como à “mudança” em espécies biológicas, segundo a tese que considera a espécie como o agregado de indivíduos. Centrar-nos-emos na proposta de Thomas Reydon, que argumenta que em biologia, o termo “espécie” refere-se a duas entidades biológicas, por si denominadas evolverons e phylons, que desempenham vários papéis epistemológicos em pelo menos duas disciplinas diferentes, n…Read more
  • Are women adult human females?
    Philosophical Studies 177 (12): 3783-3803. 2020.
    Are women (simply) adult human females? Dictionaries suggest that they are. However, philosophers who have explicitly considered the question invariably answer no. This paper argues that they are wrong. The orthodox view is that the category *woman* is a social category, like the categories *widow* and *police officer*, although exactly what this social category consists in is a matter of considerable disagreement. In any event, orthodoxy has it that *woman* is definitely not a biological catego…Read more
  • In this paper we propose an Ontology of Commercial Exchange (OCE) based on Basic Formal Ontology. OCE is designed for re-use in the Industrial Ontologies Foundry (IOF) and in other ontologies addressing different aspects of human social behavior involving purchasing, selling, marketing, and so forth. We first evaluate some of the design patterns used in the Financial Industry Business Ontology (FIBO) and Product Types Ontology (PTO). We then propose terms and definitions that we believe will imp…Read more
  • A conditional theory of trying
    Philosophical Studies 173 (1): 271-287. 2016.
    What I shall do in this paper is to propose an analysis of ‘Agent P tries to A’ in terms of a subjunctive conditional, that avoids some of the problems that beset most alternative accounts of trying, which I call ‘referential views’. They are so-named because on these alternative accounts, ‘P tries to A’ entails that there is a trying to A by P, and therefore the expression ‘P’s trying to A’ can occur in the subject of a sentence and be used to refer to a particular, namely an act or event of tr…Read more
  • We begin at the beginning, with an outline of Aristotle’s views on ontology and with a discussion of the influence of these views on Linnaeus. We move from there to consider the data standardization initiatives launched in the 19th century, and then turn to investigate how the idea of computational ontologies developed in the AI and knowledge representation communities in the closing decades of the 20th century. We show how aspects of this idea, particularly those relating to the use of the term…Read more
  • Pains and places
    Philosophy 78 (303): 5-24. 2003.
    I argue that itches, tickles, aches and pains—sensations of all sorts—are generally in the places where we say they are. So, for example, if I say that I have an itch in the big toe on my left foot, then, by and large, that is the very place where the itch is. James denied this in the 1890s; Russell and Broad denied it in the 1920s; Wittgenstein and Ryle denied it in the 1940s; Lewis and Armstrong denied it in the 1960s; and since then various kinds of materialists have denied it. But if itches …Read more
  • Nominalism and Material Plenitude
    Res Philosophica 98 (1): 89-112. 2021.
    The idea of “material plenitude” has been gaining traction in recent discussions of the metaphysics of material objects. My main goal here is to show that this idea may have important dialectical implications for the metaphysics of properties – more specifically, that it provides nominalists with new resources in their attempt to reject an ontology of universals. I will recapitulate one of the main arguments against nominalism – due to David Armstrong – and show how plenitude helps the nominalis…Read more
  • This paper critically assesses existing accounts of the nature of difficulty, finds them wanting, and proposes a new account. The concept of difficulty is routinely invoked in debates regarding degrees of moral responsibility, and the value of achievement. Until recently, however, there has not been any sustained attempt to provide an account of the nature of difficulty itself. This has changed with Gwen Bradford’s Achievement, which argues that difficulty is a matter of how much intense effort …Read more
  • Effort and Achievement
    Utilitas 29 (1): 27-51. 2017.
    Achievements have recently begun to attract increased attention from value theorists. One recurring idea in this budding literature is that one important factor determining the magnitude or value of an achievement is the amount of effort the achiever invested. The aim of this paper is to present the most plausible version of this idea. This advances the current state of debate where authors are invoking substantially different notions of effort and are thus talking past each other. While the con…Read more
  • Amongst the entities making up social reality, are there necessary relations whose necessity is not a mere reflection of the logical connections between corresponding concepts? We distinguish three main groups of answers to this question, associated with Hume and Adolf Reinach at opposite extremes, and with Searle who occupies a position somewhere in the middle. We first set forth Reinach’s views on what he calls ‘material necessities’ in the realm of social entities. We then attempt to show tha…Read more
  • Achievement
    Oxford University Press. 2015.
    Gwen Bradford presents the first systematic account of what achievements are, and why they are worth the effort. She argues that more things count as achievements than we might have thought, and offers a new perfectionist theory of value in which difficulty, perhaps surprisingly, plays a central part in characterizing achievements.
  • Is There a Problem with the Causal Criterion of Event Identity?
    Rafael De Clercq, Wai-Yin Lam, and Jiji Zhang
    American Philosophical Quarterly 51 (2): 109-119. 2014.
    In this paper, we take another look at the reasons for which the causal criterion of event identity has been abandoned. We argue that the reasons are not strong. First of all, there is a criterion in the neighborhood of the causal criterion—the counterfactual criterion—that is not vulnerable to any of the putative counterexamples brought up in the literature. Secondly, neither the causal criterion nor the counterfactual criterion suffers from any form of vicious circularity. Nonetheless, we do n…Read more
  • Women in Philosophy: Problems with the Discrimination Hypothesis
    Neven Sesardić and Rafael de Clercq
    Academic Questions 27 (4): 461-473. 2014.
    A number of philosophers attribute the underrepresentation of women in philosophy largely to bias against women or some kind of wrongful discrimination. They cite six sources of evidence to support their contention: (1) gender disparities that increase along the path from undergraduate student to full time faculty member; (2) anecdotal accounts of discrimination in philosophy; (3) research on gender bias in the evaluation of manuscripts, grants, and curricula vitae in other academic disciplines;…Read more
