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. (shrink)

In many learning or inference tasks human behavior approximates that of a Bayesian ideal observer, suggesting that, at some level, cognition can be described as Bayesian inference. However, a number of findings have highlighted an intriguing mismatch between human behavior and standard assumptions about optimality: People often appear to make decisions based on just one or a few samples from the appropriate posterior probability distribution, rather than using the full distribution. Although sampling-based approximations are a common way to implement Bayesian (...) inference, the very limited numbers of samples often used by humans seem insufficient to approximate the required probability distributions very accurately. Here, we consider this discrepancy in the broader framework of statistical decision theory, and ask: If people are making decisions based on samples—but as samples are costly—how many samples should people use to optimize their total expected or worst-case reward over a large number of decisions? We find that under reasonable assumptions about the time costs of sampling, making many quick but locally suboptimal decisions based on very few samples may be the globally optimal strategy over long periods. These results help to reconcile a large body of work showing sampling-based or probability matching behavior with the hypothesis that human cognition can be understood in Bayesian terms, and they suggest promising future directions for studies of resource-constrained cognition.

Joshua Gert presents an original account of color properties, and of our perception of them. He employs a general philosophical strategy - neo-pragmatism - which challenges an assumption made by virtually all other theories of color: he argues that colors are primitive properties of objects, irreducible to physical or dispositional properties.

If Bayesian Fundamentalism existed, Jones & Love's (J&L's) arguments would provide a necessary corrective. But it does not. Bayesian cognitive science is deeply concerned with characterizing algorithms and representations, and, ultimately, implementations in neural circuits; it pays close attention to environmental structure and the constraints of behavioral data, when available; and it rigorously compares multiple models, both within and across papers. J&L's recommendation of Bayesian Enlightenment corresponds to past, present, and, we hope, future practice in Bayesian cognitive science.

Joshua Gert offers an original account of normative facts and properties, those which have implications for how we ought to behave. He argues that our ability to think and talk about normative notions such as reasons and benefits is dependent on how we respond to the world around us, including how we respond to the actions of other people.

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. (shrink)

ABSTRACT Adverbialism is the view that to have a conscious perceptual experience is to be consciously experiencing in a certain way, and that this way is not to be understood in relational or representational terms. We might compare what it is for a conscious being to be experiencing in a certain way with what it is for a string to be vibrating in a certain way. This paper makes a new case for adverbialism by appealing to the fact that we (...) can pick out ways of experiencing by treating them as information-bearing signals. In both presenting and defending the view, it will be crucial that information is not the same as representational content, but can still concern objects and the properties of those objects. The resulting information-theoretic adverbialism can answer or deflect the most influential objections to adverbialism. (shrink)

Whether or not one endorses realism about colour, it is very tempting to regard realism about determinable colours such as green and yellow as standing or falling together with realism about determinate colours such as unique green or green31. Indeed some of the most prominent representatives of both sides of the colour realism debate explicitly endorse the idea that these two kinds of realism are so linked. Against such theorists, the present paper argues that one can be a realist about (...) the determinable colours of objects, and thus hold that most of the colour ascriptions made by competent speakers are literally true, while denying that there are any positive facts of the matter as to the determinate colours of objects. The result is a realistic colour realism that can certify most of our everyday colour ascriptions as literally correct, while acknowledging the data regarding individual variation. (shrink)

This paper calls into question the idea that moral disgust is usefully regarded as a form of genuine disgust. This hypothesis is questionable even if, as some have argued, the spread of moral norms through a community makes use of signaling mechanisms that are central to core disgust. The signaling system is just one part of disgust, and may well be completely separable from it. Moreover, there is plausibly a significant difference between the cognitive scientist’s concept of an emotion and (...) the everyday notion of that emotion. Finally, even if, as this paper contests, some form of disgust were directly elicited by the moral wrongness of certain kinds of behavior, research on the socio-moral elicitors of the disgust mechanism would still be unlikely to shed much direct light on the nature or content of morality.

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. (shrink)

In a number of recent publications, Douglas Portmore has defended consequentialism, largely on the basis of a maximizing view of practical rationality. I have criticized such maximizing views, arguing that we need to distinguish two independent dimensions of normative strength: justifying strength and requiring strength. I have also argued that this distinction helps to explain why we typically have so many rational options. Engaging with these arguments, Portmore has (a) developed his own novel maximization-friendly method of explaining the ubiquity of (...) rational options, and (b) criticized one argument in favour of a substantive justifying/requiring distinction in the domain of practical rationality. The present article defends the justifying/requiring distinction, and criticizes Portmore's maximization-friendly strategy for explaining the ubiquity of rational options. (shrink)

In The Sources of Normativity, Christine Korsgaard presents and defends a neo-Kantian theory of normativity. Her initial account of reasons seems to make them dependent upon the practical identity of the agent, and upon the value the agent must place on her own humanity. This seems to make all reasons agent-relative. But Korsgaard claims that arguments similar to Wittgenstein’s private-language argument can show that reasons are in fact essentially agent-neutral. This paper explains both of Korsgaard’s Wittgensteinian arguments, and shows why (...) neither of them work. The paper also provides a brief sketch of a different Wittgensteinian account of reasons that distinguishes the normative role of justification from that of requirement. On this account, the real agent-neutrality of reasons applies to their justificatory role, but not to their requiring role. (shrink)

One of us -- Alfred Mele (1996; 2003, ch. 5) -- has argued that possible instances of listlessness falsify the combination of cognitivism and various kinds of internalism about positive first-person moral ought-beliefs. If an argument recently advanced by James Lenman (1999) is successful, listlessnessis impossible and Mele's argument from listlessness therefore fails.However, we will argue that Lenman's argument is unpersuasive.

This article uses a particular view of the basic emotions in order to develop and defend an account of paradigmatic emotion-linked evaluative properties. The view is that felt emotions are constituted by an awareness that one is about to behave in a certain way. This view provides support for a fitting-attitude account of certain evaluative properties. But the relevant sense of fittingness is not to be understood in terms of reasons. The account therefore sidesteps the well-known Wrong Kind of Reasons (...) problem. Throughout the article, a contrast is made with the rational sentimentalism of Justin D’Arms and Daniel Jacobson.

In The Sources of Normativity, Christine Korsgaard tried to argue against what she called the ‘privacy’ of reasons, appealing to Wittgenstein's argument against the possibility of a private language. In recent work she continues to endorse Wittgenstein's perspective on the normativity of meaning, although she now emphasizes that her own argument was only meant to be analogous to the private language argument. The purpose of the present paper is to show that the Wittgensteinian perspective is not only not useful in (...) support of Korsgaard's general project, but that it is positively inimical to it, in two ways. First, Wittgenstein opposes views on which principled or rule-following behavior requires that one be guided by anything like a mental representation of a rule or principle. But for Korsgaard, human action essentially requires this. Second, Wittgenstein systematically attempts to de-emphasize the importance of the first-personal perspective, and to emphasize the social functions even of concepts that might seem deployed primarily from that perspective: for example, concepts of sensations and intentions. This is the reverse of Korsgaard's emphasis. The paper also argues, however, that the private language argument does have some implications for a theory of rationality and reasons. (shrink)

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. (shrink)

Although it goes against a widespread significant misunderstanding of his view, Michael Smith is one of the very few moral philosophers who explicitly wants to allow for the commonsense claim that, while morally required action is always favored by some reason, selfish and immoral action can also be rationally permissible. One point of this paper is to make it clear that this is indeed Smith's view. It is a further point to show that his way of accommodating this claim is (...) inconsistent with his wellknown "practicality requirement" on moral judgments: the thesis that any rational person will always have at least some motivation to do what she judges to be right. The general conclusion is that no view that, like Smith's, associates the normative strength of a reason with the motivational strength of an ideal desire will allow for the wide range of rational permissibility that Smith wants to capture.

Derek Parfit, Joseph Raz, and T. M. S canlon, among others, all hold that reasons for action are provided by facts about those actions. They also hold that the fact that an action would promote or achieve the object of an agent's desire is not one of the relevant facts, and does not provide a reason. Rather, the facts that provide reasons are typically facts about valuable states of affairs that the action is likely to bring about, or valuable properties (...) that the action itself will instantiate. For this reason it is appropriate to call Parfit, Raz, and Scanlon "value-based" theorists about reasons for action. In contrast to value-based theorists, there is a strong current of contemporary theorizing, starting with Bernard Williams, that can be called "desire-based." Desire-based theorists argue that practical reasons should be understood in terms of the desires of the agents who are said to have those reasons. (shrink)

Learning to understand a single causal system can be an achievement, but humans must learn about multiple causal systems over the course of a lifetime. We present a hierarchical Bayesian framework that helps to explain how learning about several causal systems can accelerate learning about systems that are subsequently encountered. Given experience with a set of objects, our framework learns a causal model for each object and a causal schema that captures commonalities among these causal models. The schema organizes the (...) objects into categories and specifies the causal powers and characteristic features of these categories and the characteristic causal interactions between categories. A schema of this kind allows causal models for subsequent objects to be rapidly learned, and we explore this accelerated learning in four experiments. Our results confirm that humans learn rapidly about the causal powers of novel objects, and we show that our framework accounts better for our data than alternative models of causal learning.

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. (shrink)

Julia Markovits has recently argued for what she calls the ‘Coincident Reasons Thesis’: the thesis that one’s action is morally worthy if and only if one’s motivating reasons for acting mirror, in content and strength, the reasons that explain why the action ought, morally, to be performed. This thesis assumes that the structure of motivating reasons is sufficiently similar to the structure of normative reasons that the required coincidence in content and strength is a genuine possibility. But because motivating reasons (...) have only one dimension of strength, while normative reasons have both justifying and requiring strength, one’s motivating reasons can no more coincide with the normative reasons of relevance to one’s action than a line can coincide with a square, or a square with a cube. It is possible to amend the Coincident Reasons Thesis so that it concerns only one dimension of normative strength: for example, requiring strength. But such an amended thesis yields implausible verdicts. In particular it requires us either to deny the existence of supererogatory action, or—still less plausibly—to hold that such action has less moral worth than does doing the morally required minimum.

A defender of any view of moral language must explain how people with different moral views can be be talking to each other, rather than past each other. For expressivists this problem drastically constrains the search for the specific attitude expressed by, say, ‘immoral’. But cognitivists face a similar difficulty; they need to find a specific meaning for ‘immoral’ that underwrites genuine disagreement while accommodating the fact that different speakers have very different criteria for the use of that term. This (...) paper explains how neo-pragmatism deals with this issue while avoiding problems that arise with existing expressivist and cognitivist solutions. (shrink)
