It is widely held, even among nonnaturalists, that the moral supervenes on the natural. This is to say that for any two metaphysically possible worlds w and w′, and for any entities x in w and y in w′, any isomorphism between x and y that preserves the natural properties preserves the moral properties. In this paper, I put forward a conceivability argument against moral supervenience, assuming non-naturalism. First, I argue that though utilitarianism may be true, and the trolley driver is permitted to kill the one to save the five, there is a conceivable scenario that is just like our world in all natural respects, yet at which deontology is true, and the trolly driver is not permitted to kill the one to save the five. I then argue that in the special case of morality, it is possible to infer from the conceivability of such a scenario to its possibility. It follows that supervenience is false.

This chapter discusses the application of formal methods from social choice theory to the metasemantic question of whether radical interpretation is possible. Radical interpretation involves deducing semantic truths from non-semantic truths by appeal to certain a priori principles or criteria, such as the principle of charity. A familiar view is that the intended interpretation is the one that best meets a combination of constraints. It is suggested that this situation can be modelled as follows: each constraint determines a binary relation on the set X of interpretations that is transitive and complete. The radical interpreter’s task is to determine an overall ordering as a function from the profile of individual orderings. The application of Arrow’s theorem in this context is discussed.

In Making it Explicit, Brandom aims to articulate an account of conceptual content that accommodates its normati vity-a requirement on theories of content that Brandom traces to Wittgenstein’s rule following considerations. It is widely held that the normativity requirement cannot be met, or at least not with ease, because theories of content face an intractable dilemma. Brandom proposes to evade the dilemma by adopting a middle road---one that uses normative vocabulary, but treats norms as implicit in practices. I argue that this proposal fails to evade the dilemma, as Brandom himself understands it. Despite his use of normative vocabulary, Brandom’s theory fares no better than the reductionist theories he criticises. I consider some responses that Brandom might make to my charges, and finally conclude that his proposal founders on his own criteria.

It is frequently said that belief aims at truth, in an explicitly normative sense—that is, that one ought to believe the proposition that p if, and only if, p is true. This truth norm is frequently invoked to explain why we should seek evidential justification in our beliefs, or why we should try to be rational in our belief formation—it is because we ought to believe the truth that we ought to follow the evidence in belief revision. In this paper, I argue that this view is untenable. The truth norm clashes with plausible evidential norms in a wide range of cases, such as when we have excellent but misleading evidence for a falsehood or no evidence for a truth. I will consider various ways to resolve this conflict and argue that none of them work. However, I will ultimately attempt to vindicate the love of truth, by arguing that knowledge is the proper epistemic goal. The upshot is that we should not aim merely to believe the truth; we should aim to know it.Keywords: Belief; Knowledge; Normativity; Rationality; Truth

It is highly intuitive that the future is open and the past is closed—whereas it is unsettled whether there will be a fourth world war, it is settled that there was a first. Recently, it has become increasingly popular to claim that the intuitive openness of the future implies that contingent statements about the future, such as ‘there will be a sea battle tomorrow,’ are non-bivalent (neither true nor false). In this paper, we argue that the non-bivalence of future contingents is at odds with our pre-theoretic intuitions about the openness of the future. These are revealed by our pragmatic judgments concerning the correctness and incorrectness of assertions of future contingents. We argue that the pragmatic data together with a plausible account of assertion shows that in many cases we take future contingents to be true (or to be false), though we take the future to be open in relevant respects. It follows that appeals to intuition to support the non-bivalence of future contingents is untenable. Intuition favours bivalence.

The Rules of Thought, by Jonathan Jenkins Ichikawa and Benjamin Jarvis, is a dense and ambitious book whose principal aim is to defend the view that philosophical inquiry is a priori inquiry into essential natures. The book covers a broad range of philosophical issues spanning the philosophy of mind and language, the epistemology of metaphysical modality and the philosophy of philosophy. It will be of considerable interest to many, since there is something in it for just about everyone. That said, the authors do not do as much as one might like to make their views accessible to the uninitiated or convincing to the unconverted.

Many people claim that semantic content is normative, and that therefore naturalistic theories of content face a potentially insuperable difficulty. The normativity of content allegedly undermines naturalism by introducing a gap between semantic 'ought's and the explanatory resources of naturalism. I argue here that this problem is not ultimately pressing for naturalists. The normativity thesis, I maintain, is ambiguous; it could mean either that the content of a term prescribes a pattern of use, or that it merely determines which pattern of use can be described as 'correct'. For the antinaturalist argument to go forward, content must be prescriptive. I argue, however, that it is not. Moreover, the thesis that content supplies standards for correct use is insufficient to supply a similar, a priori objection to naturalism.
