This article explains and defends the existence of value constancy, understood on the model of color constancy. Color constancy involves a phenomenal distinction between the transient color appearances of objects and the unchanging colors that those objects appear to have. The existence of value constancy allows advocates of response-dependent accounts of value to reject the question “What is the uniquely appropriate attitude to have toward this evaluative property?” as containing a false uniqueness assumption. Rejecting this assumption allows response-dependent accounts of value to deflect or answer a host of popular objections

Terry Horgan and Mark Timmons have recently presented a series of papers in which they argue against what has come to be called the ‘new wave’ moral realism and moral semantics of David Brink, Richard Boyd, Peter Railton, and a number of other philosophers. The central idea behind Horgan and Timmons’s criticism of these ‘new wave’ theories has been extended by Sean Holland to include the sort of realism that drops out of response-dependent accounts that make use of an analogy between moral properties and secondary qualities. This paper argues that Holland’s extension depends crucially on the fact that his target is a direct response-dependent account of moral value. His argument does not work against such accounts of more basic normative notions such as ‘harm’ or ‘benefit’. And these more basic notions may then serve as the basic normative building blocks for an indirectly response-dependent moral theory.

René Jagnow [2012] argues that David Rosenthal's theory of consciousness cannot account for certain experiences that involve colours so fine-grained that we do not and cannot have concepts of them. Jagnow claims that an appeal to comparative concepts such as being slightly darker than cannot help Rosenthal, since, in order to apply such concepts, we would already need to be conscious of two distinct fine-grained colours. The present paper contests this claim. It appeals to the Cornsweet illusion and some other visual phenomena, in order to argue that our visual systems can and do represent brutely comparative matters

Perceptual-role theories of mental qualities hold that we can discover the nature of a being’s mental qualities by investigating that being’s capacity to make perceptual discriminations. Many advocates of perceptual-role theories hold that the best explanation of these capacities is that mental quality spaces are homomorphic to the spaces of the physical properties that they help to discriminate. This paper disputes this thesis on largely empirical grounds, and offers an alternative. The alternative explains interesting patterns in our perception of color differences and similarities across edges, emphasizing the importance of visual discontinuities. Further, it provides a simple explanation of the intransitivity of indiscriminability. The homomorphism thesis can explain this intransitivity only with the addition of an independently unsupported empirical hypothesis. Also, in contrast to the homomorphism thesis, the alternative view is perfectly consistent with empirical data that suggest that the visual system uses the dynamic allocation of a limited range of responses in order to discriminate a wider range of physical stimuli and that we are much better at detecting changes in relative luminance than changes in absolute luminance. Moreover, it does all this while using a more efficient strategy for encoding sensory information.

This book presents an account of normative practical reasons and the way in which they contribute to the rationality of action. Rather than simply 'counting in favour of' actions, normative reasons play two logically distinct roles: requiring action and justifying action. The distinction between these two roles explains why some reasons do not seem relevant to the rational status of an action unless the agent cares about them, while other reasons retain all their force regardless of the agent's attitude. It also explains why the class of rationally permissible action is wide enough to contain not only all morally required action, but also much selfish and immoral action. The book will appeal to a range of readers interested in practical reason in particular, and moral theory more generally.

This paper offers a neo-pragmatist account of the representational character of the emotions, for those emotions that have such a character. Put most generally, neo-pragmatism is the view that language should not be conceived primarily in terms of a robust relation of reference to or representation of antecedently given objects and properties. Rather, we should view it as a social practice that lets us do various quite different sorts of things. One of those things might be called ‘assessing representational accuracy’, but this need not be thought of in terms of a metaphysically heavyweight relation. In applying neo-pragmatist techniques to the domain of the emotions, the result will be an alternative to currently popular accounts that individuate emotions partly in terms of what they represent. This alternative continues to allow us to use representational language in connection with some emotions. And it also helps to explain the awkwardness of representational talk in connection with other emotions: an awkwardness that was always a liability of monolithic representationalist views.

In “ A Light Theory of Color”, Walter Sinnott-Armstrong and David Sparrow argue that color is neither a primary quality of objects, nor a disposition that objects have, nor a property of our visual fields. Rather, according to the view they present, color is a property of light. The present paper aims to show, first, that the light theory is vulnerable to many of the very same objections that Sinnott-Armstrong and Sparrow raise against rival views. Second, the paper argues that the strategies that Sinnott-Armstrong and Sparrow use to avoid certain objections are also available to proponents of rival accounts. This might only seem to show that the light theory is in the same shaky boat as other theories: suffering from the same problems but having the same tools for solving them. The paper concludes with a suggestion as to why this is not the case, but why the existence of the light theory is nevertheless likely to bring increased clarity to the debate about color realism.

Alan Goldman’s Reasons from Within is one of the most thorough recent defenses of what might be called ‘orthodox internalism’ about practical reasons. Goldman’s main target is an opposing view that includes a commitment to the following two theses: (O) that there are such things as objective values, and (E) that these values give rise to external reasons. One version of this view, which we can call ‘orthodox externalism’, also includes a commitment to the thesis (I) that rational people will be motivated by any reason they have of which they are aware. Goldman himself embraces (I), and deploys it frequently in his criticisms of orthodox externalism. But there is logical space for an externalist view that includes a commitment to (O) and (E), but that denies (I). The resulting “hyperexternalist” view holds that some reasons need not motivate us, even if we are rational. In this paper I argue that Goldman’s criticisms of orthodox externalism leave hyperexternalism untouched, and that his specific criticisms of my own version of hyperexternalism do not work. In light of Goldman’s criticisms of orthodox externalism and my own criticisms of Goldman’s view, hyperexternalism emerges as the favored option

Jason Stanley has criticized a contextualist solution to the sorites paradox that treats vagueness as a kind of indexicality. His objection rests on a feature of indexicals that seems plausible: that their reference remains fixed in verb phrase ellipsis. But the force of Stanley’s criticism depends on the undefended assumption that vague terms, if they are a special sort of indexical, must function in the same way that more paradigmatic indexicals do. This paper argues that there can be more than one sort of indexicality, that one term might easily have both sorts, and that therefore, and despite Stanley’s worries, vagueness might easily be assimilated to one form.

This article attempts to do two things. The first is to make it plausible that any adequate dispositional view of color will have to associate colors with complex functions from a wide range of normal circumstances to a wide range of (simultaneously) incompatible color appearances, so that there will be no uniquely veridical appearance of any given color. The second is to show that once this move is made, dispositionalism is in a position to provide interesting answers to some of the most challenging objections that have been pressed against it. It explains why colors do not seem to come on when the lights come on, and why the right thing to say seems to be that the light causes the objects to reveal their colors. It explains why the content of visual experience need not be problematically circular. It eliminates the problem of intrapersonal variation in color appearance. And it even provides resources for dealing with the problem of interpersonal variation. It is true that in moving to the more complex view, the dispositionalist becomes subject to a new objection, which has been called the problem of unity. The paper offers a solution to this problem as well.

Ruth Chang has argued for the existence of a fourth positive value relation, distinct from betterness, worseness and equality, which she calls “parity.” In an earlier article I seemed to criticize Chang's suggestion by offering an interval model for the values of items that I claimed could accommodate all the phenomena characteristic of parity. Wlodek Rabinowicz, offering his own model of value relations, endorsed one central feature of my proposal: the need to distinguish permissible preferences from required ones. But he, along with Chang, correctly pointed out that my own model suffered from serious formal problems. The present article offers an improved interval model, but the main point is not the model itself. Rather, it is the derivation of the model from a response-dependent account of practical rationality. This derivation helps explain why we have a concept for which Rabinowicz's model is appropriate, and therefore supplements Chang's existence arguments. My conclusion is that we can take Chang's view, Rabinowicz's and mine as providing a reinforcing set of views

Response-dispositional accounts of value defend a biconditional in which the possession of an evaluative property is said to covary with the disposition to cause a certain response. In contrast, a fitting-attitude account of the same property would claim that it is such as to merit or make fitting that same response. This paper argues that even for secondary qualities, response-dispositional accounts are inadequate; we need to import a normative notion such as appropriateness even into accounts of such descriptive properties as redness. A preliminary conclusion is that the normativity that appears in fitting-attitude accounts of evaluative properties need not have anything to do with the evaluative nature of those properties. It may appear there because evaluative properties—or at least thosefor which fitting-attitude accounts are plausible—really are so much like secondary qualities that it might well be appropriate to think of them as a subclass of secondary qualities. In the second half of the paper I discuss the views of three of the philosophers who have been most influential in discussions of response-featuring accounts of evaluative notions and who explicitly distinguish response-dispositional accounts of value from fittingattitude accounts: John McDowell, Simon Blackburn, and Crispin Wright. I highlight some of the theoretical temptations that can be associated with the assumption that the response-dispositional/fitting-attitude distinction parallels the secondary quality/evaluative property distinction.

In The Red and the Real, Jonathan Cohen defends a relationalist view of color: the view that colors are constituted by relations between objects, perceivers, and circumstances. Cohen’s defense of relationalism is often ingenious, but it also commits him to some extremely counterintuitive—one might say “crazy”—claims. The present paper argues that the phenomena that are captured by Cohen’s ingenious defense of his interesting view can be captured equally well by a more “boring” view. Such a view distinguishes between colors and the ways that those colors appear to various viewers, takes colors to be relatively vague, and claims that other species with color vision simply see other colors. Since the boring view stays closer to common sense on many points, it is to be preferred.

This paper offers one formal reason why it may often be inappropriate to hold, of two conflicting desires, that the first must be weaker than, stronger than, or of the same strength as the second. The explanation of this fact does not rely on vagueness or epistemological problems in determining the strengths of desires. Nor does it make use of the problematic notion of incommensurability. Rather, the suggestion is that the motivational capacities of many desires might best be characterized by two values, neither of which should be interpreted as strength.
