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 Rønnow-Rasmussen (2003). I begin by explaining why the reduction is appealing in the first place. In my rejoinder to Rabinowicz and Rønnow-Rasmussen I defend trope-value reductionism against three challenges. I focus mainly on their central objection, that holds that the reduction is untenable since different evaluative attitudes have, ontologically speaking, different objects. I grant that this may well be so, but argue that the objection is based on an unwarranted, loose reading of the notion 'value for its own sake'. On the more reasonable strict reading, it is plausible to maintain that tropes are the sole ontological category that can properly be ascribed final value

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 metaethics, that is, his account of vulgar moral thought and discourse, and his revisionary metaethics, that is, his account of how vulgar moral thought and discourse could be reformed so as to no longer involve error. This essay concludes that Hume is a projectivist and an error theorist in descriptive metaethics, while he is a projectivist and a subjectivist in revisionary metaethics.

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 both non-cognitivist and cognitivist elements, fails to meet Smith's challenge, it is unlikely that 'purer' and more familiar versions of non-cognitivism will succeed.

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 prevalent among undergraduates and non-philosophers. It leaves for expressivists two awkward explanatory tasks. Number one is that of explaining why natural selection – which, by expressivism's own lights, favoured moral thought and talk because of their socially useful regulative and coordinating functions – did not favour a stance that would make moral thought and talk more effective in fulfilling these functions. Number two is that of explaining how moral thought and talk survive in cultural evolution, despite the prevalence of the freshman objection and related worries. I conclude that expressivism as a theory of actual moral discourse rather than a revisionist theory is either false or committed to an implausible error theory, according to which ordinary speakers are systematically mistaken about what they are up to when they make moral judgements.
