This paper argues against both conceptual and linguistic analysis as sources of a priori knowledge. Whether such knowledge is possible turns on the nature of concepts. The paper's chief contention is that none of the main views about what concepts are can underwrite the possibility of such knowledge.

Recent work by Joshua Knobe indicates that people’s intuition about whether an action was intentional depends on whether the outcome is good or bad. This paper argues that part of the explanation for this effect is that there are stable individual differences in how ‘intentional’ is interpreted. That is, in Knobe’s cases, different people interpret the term in different ways. This interpretive diversity of ‘intentional’ opens up a new avenue to help explain Knobe’s results. Furthermore, the paper argues that the (...) use of intuitions in philosophy is complicated by fact that there are robust individual differences in intuitions about matters of philosophical concern.

It has been standard philosophical practice in analytic philosophy to employ intuitions generated in response to thought-experiments as evidence in the evaluation of philosophical claims. In part as a response to this practice, an exciting new movement—experimental philosophy—has recently emerged. This movement is unified behind both a common methodology and a common aim: the application of methods of experimental psychology to the study of the nature of intuitions. In this paper, we will introduce two different views concerning the relationship that (...) holds between experimental philosophy and the future of standard philosophical practice (what we call, the proper foundation view and the restrictionist view), discuss some of the more interesting and important results obtained by proponents of both views, and examine the pressure these results put on analytic philosophers to reform standard philosophical practice. We will also defend experimental philosophy from some recent objections, suggest future directions for work in experimental philosophy, and suggest what future lines of epistemological response might be available to those wishing to defend analytic epistemology from the challenges posed by experimental philosophy.

This paper concerns the applications of two-dimensional modal semantics to the explanation of the contents of speech and thought. Different interpretations and applications of the apparatus are contrasted. First, it is argued that David Kaplan's two-dimensional semantics for indexical expressions is different from the use that I made of a formally similar framework to represent the role of contingent information in the determination of what is said. But the two applications are complementary rather than conflicting. Second, my interpretation of the (...) apparatus is contrasted with that of David Chalmers, Frank Jackson, and David Lewis. It is argued that this difference reflects a contrast between internalist and externalist approaches to the problem of intentionality. (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.

I am a friend of supervaluationism. A statement lacks a definite truth value if, and only if, it comes out true on some admissible ways of precisifying the semantics of the relevant vocabulary and false on others. In this paper, I focus on the special case of identity statements. I take it that such statements, too, may occasionally suffer a truth-value gap, including philosophically significant instances. Yet there is a potentially devastating objection that can be raised against the supervaluationist treatment (...) of such cases—in fact two objections. Luckily, both can be resisted. But seeing how requires that we take a closer look at the ontological presuppositions of supervaluationism, allowing for more leeway than is usually supposed. (shrink)

Do we have free will? Understanding free will as the ability to act freely, and free actions as exercises of this ability, I maintain that the default answer to this question is “yes.” I maintain that free actions are a natural kind, by relying on the influential idea that kinds are homeostatic property clusters. The resulting position builds on the view that agents are a natural kind and yields an attractive alternative to recent revisionist accounts of free action. My view (...) also overcomes difficulties confronted by previous views according to which free actions might be a natural kind. On my view, free actions exist and we often act freely, as long as we possess various features that are related in the right sorts of ways to each other and to the world. In turn, we acquire and retain the concept as long as most of us possess enough of those features. (shrink)

This paper raises an objection to two important arguments for reductive ethical naturalism. Reductive ethical naturalism is the view that ethical properties reduce to the properties countenanced by the natural and social sciences. The main arguments for reductionism in the literature hold that ethical properties reduce to natural properties by supervening on them, either because supervenience is alleged to guarantee identity via mutual entailment, or because non-reductive supervenience relations render the supervenient properties superfluous. After carefully characterizing naturalism and reductionism, we (...) will present, explain, and raise objections against each of the main reductionist arguments: that supervenience does not support the claim that ethical properties and their subvenient natural properties are mutually entailing; that reductive views undermine the claim that ethical properties yield resemblance; and that supervenience does not entail that non-descriptive ethical properties are superfluous in the most fundamental sense.

Philosophers often hold that the aim of conceptual analysis is to discover the representational content of a given concept such as freewill, belief, or law. In From Metaphysics to Ethics and other recent work, Frank Jackson has developed a theory of conceptual analysis that is one of the most advanced systematizations of this widespread idea. I argue that this influential way of characterizing conceptual analysis is too narrow. I argue that it is possible that an expressivist account could turn out (...) to be correct as a genuine conceptual analysis of a genuine concept. I claim that since an expressivist analysis does not aim to discover the representational content of a given concept—and, indeed, might itself be based on the idea that the concept in question is not even representational in nature—the possibility of expressivist conceptual analysis shows that Jackson’s theory of conceptual analysis is incomplete as it currently stands. I conclude that Jackson needs to either shift his basic understanding of the nature of conceptual analysis or commit to a particular normative reinterpretation of his project. (shrink)

Antiques are undoubtedly objects worthy of aesthetic appreciation, but do they have a distinctive aesthetic value in virtue of being antiques? In this article we give an account of what it is to be an antique that gives the thesis that they do have a distinctive aesthetic value a chance of being true and suggests what that distinctive value consists in. After introducing our topic in Section I, in Section II we develop and defend the Adjectival Thesis: the thesis that (...) the concept of being an antique is an adjectival concept. This provides us with the means to formulate our definition, which we do in Section III. In Section IV we further explicate and defend our definition. In Section V we conclude by briefly saying where we think our definition could be improved, by making a few comments about the aesthetics of antiques and by stating an interesting consequence of our definition: that it is not analytic that antiques are old.

In “How Facts Make Law” and other recent work, Mark Greenberg argues that legal positivists cannot develop a viable constitutive account of law that meets what he calls the “the rational-relation requirement.” He argues that this gives us reason to reject positivism in favor of antipositivism. In this paper, I argue that Greenberg is wrong: positivists can in fact develop a viable constitutive account of law that meets the rational-relation requirement. I make this argument in two stages. First, I offer (...) an account of the rational-relation requirement. Second, I put forward a viable positivist account of law that I argue meets this requirement. The account that I propose is a version of Scott Shapiro’s Planning Theory of Law. The version of Shapiro’s account that I propose combines (1) the account of concepts and conceptual analysis put forward by David Chalmers and Frank Jackson with (2) the account of the concept LEGAL INSTITUTION (and its conceptual connections to the concept LEGAL NORM) that we get from a certain reading of Shapiro’s Planning Theory. In addition to providing a compelling response to Greenberg’s argument in “How Facts Make Law,” I argue that the explanation for why my response to Greenberg works underscores one of the central problems facing legal antipositivism: namely, its lack of a convincing account of the nature of legal institutions.
