Based on a conception that a musical composition is constituted by normative properties, it is argued that every such composition has one ideal performance—a performance that fulfils all the aesthetic-normative properties that the composition determines. A performance is conceived of (and evaluated) as inherently and essentially ‘intentionalistic’—being, by its very nature, a performance of a certain composition. This conception allows for various different performances, none of which is preferable over the others. The properties concerned are conceived of broadly as comprising not only the tones themselves and various ‘theoretical’ features such as thematic relations, harmonic progressions, rhythmical structures, but also descriptive, emotive, and ‘rhetorical’ properties, which are ‘objective’ properties of the composition. It is further claimed that these are indicated in the score when properly understood in the light, inter alia, of pertinent conventions, which are the business of theoreticians and musicologists to determine. The main significance of the result lies both in highlighting some important implications of the intentionalistic character of a performance, and in the style of conceptual connection it indicates between a musical composition, its aesthetic-normative properties, and features of performance or ways of fulfilling them.

Ethical descriptivism is the view that all ethical properties are descriptive properties. Frank Jackson has proposed an argument for this view which begins with the premise that the ethical supervenes on the descriptive, any worlds that differ ethically must differ also descriptively. This paper observes that Jackson's argument has a curious structure, taking a linguistic detour between metaphysical starting and ending points, and raises some worries stemming from this. It then proposes an improved version of the argument, which avoids these worries, and responds to some potential objections to this version of the argument.

Non-reductive moral realism is the view that there are moral properties which cannot be reduced to natural properties. If moral properties exist, it is plausible that they strongly supervene on non-moral properties- more specifically, on mental, social, and biological properties. There may also be good reasons for thinking that moral properties are irreducible. However, strong supervenience and irreducibility seem incompatible. Strong supervenience entails that there is an enormous number of modal truths (specifically, truths about exactly which non-moral properties necessitate which moral properties); and all these modal truths must be explained. If these modal truths can all be explained, then it must be a fundamental truth about the essence of each moral property that the moral property is necessarily equivalent to some property that can be specified purely in mental, social and biological terms; and this fundamental truth appears to be a reduction of the moral property in question. The best way to resist this argument is by resorting to the claim that mental and social properties are not, strictly speaking, natural properties, but are instead properties that can only be analysed in partly normative terms. Acceptance of that claim is the price of non-reductive moral realism.

In this essay, I defend a view I call “Robust Realism” about normativity. According to this view, there are irreducibly, perfectly objective, normative truths, that when successful in our normative inquiries we discover rather than create or construct. My argument in support of Robust Realism is modeled after arguments from explanatory indispensability common in the philosophy of science and the philosophy of mathematics. I argue that irreducibly normative truths, though not explanatorily indispensable, are nevertheless deliberatively indispensable, and that this kind of indispensability is just as respectable as the more familiar explanatory kind. Deliberative indispensability, I argue, justifies belief in normative facts, just like the explanatory indispensability of, say, theoretical entities like electrons justifies belief in electrons. In the introduction I characterize the view I will be arguing for and sketch the main argument of this essay. In chapter 1 I draw the analogy between explanatory and deliberative indispensability, and argue that there is no non-question-begging reason to take the former but not the latter seriously. Here I also present the master-argument of the thesis, and clarify the argumentative work that needs to be done by each of the following chapters. In chapter 2 I address the worries of the antirealist who is willing to reject arguments from explanatory indispensability as well. In other words, in this chapter I try to justify the move from indispensability (of whatever kind) to belief. In chapter 3 I develop an account of deliberation that supports the premises about deliberation needed for my master-argument to go through. In chapter 4 I reject some alternative views, showing that none of them can allow for sincere deliberation. In this chapter, in other words, I support the indispensability premise: I argue that it really is impossible to deliberate sincerely without believing in irreducibly normative truths..

For some time now, Jaegwon Kim has argued that irreducible mental properties face the threat of causal inefficacy. The primary weapon he deploys to sustain this charge is the supervenience/exclusion argument. This argument, in a nutshell, states that any mental property that irreducibly supervenes on a physical property is excluded from causal efficacy because the underlying physical property takes care of all of the causal work itself. Originally intended for mental properties alone, it did not take long for his critics to suggest the argument generalizes across all of the special science properties as well. Kim responds in two different ways to the generalization problem. The first response, which I call the higher-level solution, is ably dismissed by numerous critics. The second response, which I call the identity solution, has not faced comparable scrutiny. In this paper I argue that the identity solution faces numerous problems of its own.

According to the error theory, normative judgements are beliefs that ascribe normative properties to objects, even though such properties do not exist. In this paper, I argue that we cannot fully believe the error theory, and that this means that there is no reason for us to fully believe this theory. It may be thought that this is a problem for the error theory, but I argue that it is not. Instead, I argue, our inability to fully believe the error theory undermines many objections that have been made to this theory.

Pan-Dispositionalism – the view that all properties (and relations) are irreducibly dispositional – currently appears to have no takers amongst major analytic metaphysicians. There are those, such as Mumford, who are open to the idea but remain uncommitted. And there are those, such as Ellis and Molnar, who accept that some properties are irreducibly dispositional but argue that not all are. In this paper, I defend Pan-Dispositionalism against this ‘Moderate’ Dispositionalism.

Jonathan Dancy thinks that there are irreducibly normative properties. Frank Jackson has given a well-known argument against this view, and I have elsewhere defended this argument against many objections, including one made by Dancy. But Dancy remains unconvinced. In this chapter, I hope to convince him.

Some philosophers think that normative properties are identical to descriptive properties. In this paper, I argue that this entails that it is possible to say which descriptive properties normative properties are identical to. I argue that Frank Jackson’s argument to show that this is possible fails, and that the objections to this argument show that it is impossible to say which descriptive properties normative properties are identical to. I conclude that normative properties are not identical to descriptive properties. I then show that if we combine this conclusion with the conclusion of a different argument that Jackson has given to show that there are no irreducibly normative properties, it follows that there are no normative properties at all.

It has been argued that nonreductive physicalism leads to epiphenominalism about mental properties: the view that mental events cannot cause behavioral effects by virtue of their mental properties. Recently, attempts have been made to develop accounts of causal relevance for irreducible properties to show that mental properties need not be epiphenomenal. In this paper, I primarily discuss the account of Frank Jackson and Philip Pettit. I show how it can be developed to meet several obvious objections and to capture our intuitive conception of degrees of causal relevance. However, I argue that the account requires large-scale miraculous coincidence for there to be causally relevant mental properties. I also argue that the same problem arises for two apparently very different accounts of causal relevance. I suggest that this result does not show that these accounts, on appropriate readings, are false. Therefore, I tentatively conclude that we have reason to believe that irreducible mental properties are causally irrelevant. Moreover, given that there is at leastprima facie evidence that mental properties can be causally relevant, my conclusion casts doubt on nonreductive physicalist theories of mental properties.
