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.

In recent years, two-dimensional (2D) semantics has been used to develop a broadly descriptivist approach to meaning that seeks to accommodate externalists’ counterexamples to traditional descriptivism. The 2D possible worlds framework can be used to capture a speaker’s implicit dispositions to identify the reference of her words on the basis of empirical information about her actual environment. Proponents of 2D semantics argue that this aspect of linguistic understanding plays the core theoretical role of meanings: 2D semantics allows us to specify (...) a reference-fixing criterion implicit mastery of which constitutes semantic competence a particular meaning.

This paper develops and defends the view that substantively normative uses of words like “good”, “right” and “ought” are irresolvably indeterminate: any single case of application is like a borderline case for a vague or indeterminate term, in that the meaning-fixing facts, together with the non-linguistic facts, fail to determine a truth-value for the target sentence in context. Normative claims, like vague or indeterminate borderline claims, are not meaningless, though. By making them, the speaker communicates information about the precisifications that (...) s/he accepts. The analogy with vague/indeterminate language, I argue, lays out a new and interesting foundation for a subjectivist approach to normativity. (shrink)

Kripke and Putnam have convinced most philosophers that we cannot do metaphysics of nature by analysing the senses of natural kind terms -- simply because natural kind terms do not have senses. Neo-descriptivists, especially Frank Jackson and David Chalmers, believe that this view is mistaken. Merging classical descriptivism with a Kaplan-inspired two-dimensional framework, neo-descriptivists devise a semantics for natural kind terms that assigns natural kind terms so-called 'primary intensions'. Since primary intensions are senses by other names, Jackson and Chalmers conclude (...) that we can and should do metaphysics of nature by analysing the natural kind concepts competent speakers possess. I argue that neo-descriptivism does not provide a suitable basis for doing this kind of metaphysics. I first of all give a detailed account of the neo-descriptivist semantics and deflate the intuitive support neo-descriptivists try to draw from their case of the XYZ-world. I then present three arguments -- the Argument from Ignorance, the Argument from Conceptual Analysis, and the Argument from Laziness. Taken together, these arguments undermine the neo-descriptivist analysis of natural kind terms. I conclude that natural kind terms do not have senses, that we cannot do metaphysics of nature by analysing the senses of our kind terms, and that the Kripke-Putnam account still provides the best semantics for natural kind terms we have.

Moral discourse allows for speakers to disagree in many ways: about right and wrong acts, about moral theory, about the rational and conative significance of moral failings. Yet speakers’ eccentricities do not prevent them from engaging in moral conversation or from having (genuine, not equivocal) moral disagreement. Thus differences between speakers are compatible with possession of moral concepts. This paper examines various kinds of moral disagreements and argues that they provide evidence against conceptual-role and informational atomist approaches to understanding our (...) moral concepts. Conceptual role approaches fail because they cannot account for shared concepts among speakers with different commitments to the practical and conative ramifications of moral judgments. Informational atomist views fail because speakers need not be locked on to the same moral properties to share moral concepts. (shrink)

Contemporary discussions of race and racism devote considerable effort to giving conceptual analyses of these notions. Much of the work is concerned to investigate a priori what we mean by the terms ‘ race ’ and ‘racism’ ; more recent work has started to employ empirical methods to determine the content of our “folk concepts,” or “folk theory” of race and racism. In contrast to both of these projects, I have argued elsewhere that in considering what we mean by these (...) terms we should treat them on the model of kind terms whose reference is fixed by ordinary uses, but whose content is discovered empirically using social theory; I have also argued that it is not only important to determine what we actually mean by these terms, but what we should mean, i.e., what type, if any, we should be tracking. My own discussion of these issues, however, has been confused and confusing. In giving an account of race or gender, is the goal to provide a conceptual analysis? Or to investigate the kinds we are referring to? To draw attention to different kinds? To stipulate new meanings? Jennifer Saul has raised a series of powerful objections to my accounts of gender and race, suggesting that they are neither semantically nor politically useful, regardless of whether we treat them as revisionary proposals, or as elucidations of our concepts. Joshua Glasgow has also offered a critique of my externalist approach to race as an effort to capture “our concept”. I agree with much of what they say, but I also believe that there is something I was trying to capture that. (shrink)

I first argue that there are many true claims of the form: Φ-ing would be morally required, if anything is. I then explain why the following conditional-type is true: If φ-ing would be morally required, if anything is, then anything is actually morally required. These results allow us to construct valid proofs for the existence of some substantive moral facts—proofs that some particular acts really are morally required. Most importantly, none of my argumentation presupposes any substantive moral claim; I use (...) only plausible claims that most moral skeptics and error theorists can and do accept. The final section diagnoses why my arguments work. Here, I offer an explanation for the supervenience of the moral on the non-moral that may help those worried that the strategy is a sophisticated trick. I conclude by considering two objections. In replying to these objections, I explain why the strategy may allow us to demonstrate more than “obvious” moral truths, and why it may also address a stronger version of error theory, according to which, moral truths are not possible.

Two-dimensional (2D) semantics is a formal framework that is used to characterize the meaning of certain linguistic expressions and the entailment relations among sentences containing them. 2D semantics has also been applied to thought contents. In contrast with standard possible worlds semantics, 2D semantics assigns extensions and truth-values to expressions relative to two possible world parameters, rather than just one. So a 2D semantic framework provides finer-grained semantic values than those available within standard possible world semantics, while using the same (...) basic model-theoretic resources. The 2D framework itself is just a formal tool. To develop a semantic theory for someone’s language, a proponent of 2D semantics must do three things: (i) explain what exactly the two possible world parameters represent, (ii) explain the rules for assigning 2D semantic values to a person’s words and sentences, and (iii) explain how 2D semantic values help in understanding the meanings of the person’s words and sentences.
