Research Activity

My main research is in ethics and metaethics. I also have longstanding interests in philosophical debates around naturalism, expressivism, evolutionary accounts of morality, Humeanism about motivation, and generally all things Hume. More widely, I am also interested in the philosophy of language, and in particular in theories of vagueness. Lately I've been thinking a lot about moral vagueness.

My current research project is an investigation of ‘moral vagueness’, by which I mean the vagueness of moral predicates. The phenomenon has not received much attention thus far. But many lessons - both for moral philosophers and for philosophers of language - can be drawn from the careful study of moral vagueness.

One line of enquiry within this project concerns the metaethical implications of moral vagueness. I have argued in a recent paper that moral vagueness poses a dilemma for non-naturalist versions of metaethical realism. I am currently working on two more papers exploring related matters: in one I investigate the prospects of a quasi-realist account of moral vagueness in terms of ambivalence; in the other I explore the specific ways in which naturalists can account for vagueness, focusing on the proposed analogy between moral predicates and natural kind terms.

A second line of research concerns the links between vagueness and incommensurability. One of the views I seek to defend is that comparative predicates (e.g., ‘better than’, or ‘kinder than’) exhibit a sui generis form of vagueness I call ‘comparative vagueness’, which has fascinating implications for the way in which we make comparative judgments. I have recently completed a paper in which I argue that comparative vagueness bears on Parfit’s so called ‘repugnant conclusion’, and on the failures of transitivity discussed by philosophers such as Rachels and Temkin. I am also currently drafting a longer paper in which I shed light on the question whether evaluative predicates like ‘good’ are reducible to their comparative forms.
