A perfectly matched layer (PML) absorbing material composed of a uniaxial anisotropic material is presented for the truncation of finite-difference time-domain (FDTD) lattices. It is shown that the uniaxial PML material formulation is mathematically equivalent to the perfectly matched layer method published by Berenger (see J. Computat. Phys., Oct. 1994). However, unlike Berenger's technique, the uniaxial PML absorbing medium presented in this paper is based on a Maxwellian formulation. Numerical examples demonstrate that the FDTD implementation of the uniaxial PML medium (...) is stable, equal in effectiveness as compared to Berenger's PML medium, while being more computationally efficient.

Theories of practical reason must meet a psychological requirement: they must explain how normative practical reasons can be motivationally efficacious. It would be pointless to claim that we are subject to normative demands of reason, if we were in fact unable to meet those demands. Concerning this requirement to account for the possibility of rational motivation, internalist approaches are distinguished from externalist ones. I defend internalism, whilst rejecting both ways in which the belief‐desire model can be instantiated. Both the Humean (...) and the Kantian instantiation of that model fail to account for the internal connection between normative and motivating reasons required by internalism. The two classes of reasons rather come to be seen as mutually exclusive. Opposing the belief‐desire model, I argue that rational motivation can only be established by reference to emotion. Emotions are affective perceptions. They have motivational force so that they can contribute to the explanation of action. At the same time they can rationalise actions because they have an intentional content which resembles the content of sensory perception in being representational. Because of this, the emotions can noninferentially justify judgements, which in turn can justify actions. I conclude by outlining the Aristotelian account of practical reason and ethics that emerges from integrating the emotions into practical reasoning. Doing the right thing is much more a matter of seeing things right than of drawing the right inferences. Seeing things right, in its turn, is not only to justify an action: it necessarily implies to be motivated to act accordingly. (shrink)

A while ago I pulled the short straw, and became chair of my department. One nice part of the job is to praise people I work with, which I can do sincerely because they are very praiseworthy. I also have to read a lot of praise by others; the familiar things—project evaluations, letters of recommendation, promotion dossiers, and so on and so forth. As a result, I have learnt to attend to praise a little more closely.

It is often claimed that emotions are linked to formal objects. But what are formal objects? What roles do they play? According to some philosophers, formal objects are axiological properties which individuate emotions, make them intelligible and give their correctness conditions. In this paper, I evaluate these claims in order to answer the above questions. I first give reasons to doubt the thesis that formal objects individuate emotions. Second, I distinguish different ways in which emotions are intelligible and argue that (...) philosophers are wrong in claiming that emotions only make sense when they are based on prior sources of axiological information. Third, I investigate how issues of intelligibility connect with the correctness conditions of emotions. I defend a theory according to which emotions do not respond to axiological information, but to non-axiological reasons. According to this theory, we can allocate fundamental roles to the formal objects of emotions while dispensing with the problematic features of other theories. (shrink)

I argue that a right action has moral worth if and only if it is done for the right reasons - that is, for its right-making features. The reasons the agent acts on have to be identical to the reasons for which the action is right. I argue that Kantians are wrong in thinking that a right action has moral worth iff it is done because the agent thinks it is right, giving examples of morally worthy actions that are done (...) by agents who think they are wrong (Huckleberry Finn) and right actions done "because they are right" that have no moral worth. I also discuss degrees of moral worth as well as blameworthiness. (shrink)

I discuss two ways in which emotions explain actions: in the first, the explanation is expressive; in the second, the action is not only explained but also rationalized by the emotion's intentional content. The belief-desire model cannot satisfactorily account for either of these cases. My main purpose is to show that the emotions constitute an irreducible category in the explanation of action, to be understood by analogy with perception. Emotions are affective perceptions. Their affect gives them motivational force, and they (...) can rationalize actions because, like perception, they have a representational intentional content. Because of this, an emotion can non-inferentially justify a belief which in its turn justifies or rationalizes an action; so emotions may constitute a source of moral knowledge. (shrink)

I discuss a large number of emotions that are relevant to performance at epistemic tasks. My central concern is the possibility that it is not the emotions that are most relevant to success of these tasks but associated virtues. I present cases in which it does seem to be the emotions rather than the virtues that are doing the work. I end of the paper by mentioning the connections between desirable and undesirable epistemic emotions.

This text addresses a problem that is not sufficiently dealt with in most of the recent literature on emotion and feeling. The problem is a general underestimation of the extent to which affective intentionality is essentially bodily. Affective intentionality is the sui generis type of world-directedness that most affective states – most clearly the emotions – display. Many theorists of emotion overlook the extent to which intentional feelings are essentially bodily feelings. The important but quite often overlooked fact is that (...) the bodily feelings in question are not the regularly treated, non-intentional bodily sensations (known from Jamesian accounts of emotion), but rather crucial carriers of world-directed intentionality. Consequently, most theories of human emotions and feelings recently advocated are deficient in terms of phenomenological adequacy. This text tries to make up for this deficit and develops a catalogue of five central features of intentional bodily feelings. In addition, Jesse Prinz’s embodied appraisal theory is criticized as an exemplary case of the misconstrual of the bodily nature of affective experience in naturalistic philosophy of mind. (shrink)

Granted that desire is always present in the genesis of human action, is it something on the presence of which the agent always reflects? I may act on a belief without coming to recognize that I have the belief. Can I act on a desire without recognizing that I have the desire? In particular, can the desire have a motivational presence in my decision making, figuring in the background, as it were, without appearing in the content of my deliberation, in (...) the foreground? We argue, perhaps unsurprisingly, that yes, desire can figure in the background without figuring in the foreground: we call this the strict background view of desire. But we then show, and this is where the surprise comes, that the strict background view of desire has significant implications for contemporary moral philosophy. (shrink)

The challenge of explaining the emotions has engaged the attention of the best minds in philosophy and science throughout history. Part of the fascination has been that the emotions resist classification. As adequate account therefore requires receptivity to knowledge from a variety of sources. The philosopher must inform himself of the relevant empirical investigation to arrive at a definition, and the scientist cannot afford to be naive about the assumptions built into his conceptual apparatus. The contributors to this volume have (...) approached the problem of characterizing and classifying emotions from the perspectives of neurophysiology, psychology, and social psychology as well as that of philosophical psychology. They discuss the difficulties that arise in classifying the emotions, assessing their appropriateness and rationality, and determining their function in motivating moral action. (shrink)

Ira Brevis furor, said the Latins: anger is a brief bout of madness. There is a long tradition that views all emotions as threats to rationality. The crime passionnel belongs to that tradition: in law it is a kind of “brief-insanity defence.” We still say that “passion blinds us;” and in common parlance to be philosophical about life's trials is to be decently unemotional about them. Indeed many philosophers have espoused this view, demanding that Reason conquer Passion. Others — from (...) Hume to the Emotivists — have appeared to reverse this hierarchy.” But those philosophers who refuse to join in the general denigration of emotion as irrational usually share the presupposition that the role of rationality is limited to the calculation of means. In so far as emotions are concerned with the determination of ends, they remain, on this view, beyond the pale of rationality. Modern decision theorists have worked out schemes to assess the rationality of desires, as well as actions, against the background of beliefs and other desires.1 But these schemes leave no room at all for emotions, except, by implication, as disrupters of the rational process.

Abstract The content of an emotion, unlike the content of a perception, is directly dependent on the motivational set of the subject experiencing the emotion. Given the instability of this motivational set, it might be thought that there is no sense in which emotions can be said to pick up information about the environment in the same way that perception does. Whereas it is admitted that perception tracks for us what is the case in the environment, no such tracking relation, (...) it is argued, holds between one's emotions and what they are about. It is to this worry – that the construal of the emotions as perceptions inevitably raises – that this paper tries to respond. In this paper, I suggest that when it is realized that one dimension of perception itself is directly dependent on the perceiver's perspective on her environment, then emotion, which is also essentially perspectival in this sense, bears the comparison with perception very well. After having clarified the nature and the role that perspective plays in perception, I argue that, in the case of emotions, the same perspectival role can be played by agents’ long-standing evaluative tendencies and character traits. The resulting conception of emotion as perception is then tested against possible objections. (shrink)

I argue that emotions are belief/desire sets characterized by strong desire.

Perceptual theories of emotion purport to avoid the problems of traditional cognitivism and noncognitivism by modelling emotion on perception, which shares the most conspicuous dimensions of emotion, intentionality and phenomenality. In this paper, I shall reconstrue and discuss four key arguments that perceptual theorists have presented in order to show that emotion is a kind of perception, or that there are close analogies between emotion and perception. These arguments are, from stronger to weaker claims: the perceptual system argument; the argument (...) from noninferential structure; the argument from epistemic role; and the argument from phenomenology. I argue that, while the arguments in favour of assimilating emotion to perception fail, the analogies between emotion and perception are not as close as perceptual theorists suggest even if some emotions resemble perception more than others, thanks to the two-levelled structure of emotional processing.

DO WE CHOOSE OUR EMOTIONS? Can we be held responsible for our anger? for feeling jealousy? for falling in love or succumbing to resentment or hatred? The suggestion sounds odd because emotions are typically considered occurrences that happen to us: emotions are taken to be the hallmark of the irrational and the disruptive. Controlling one’s emotion is supposed to be like the caging and taming of a wild beast, the suppression and sublimation of a Freudian "it.".

There is a view of the emotions (I might tendentiously call it ‘cognitivism’) that has at present a certain currency. This view is of the emotions as playing an essential role in our gaining evaluative knowledge of the world. When we are angry at an insult, or afraid of the burglar, our emotions involve evaluative perceptions and thoughts, which are directed towards the way something is in the world that impinges on our well-being, or on the well-being of those that (...) matter to us. Without emotions, we would be worse off, prudentially and morally: we would not see things as they are, and accordingly we would not act as we should. Emotions are, according to this view a Good Thing. No wonder we have evolved as creatures capable of emotion.[1]. (shrink)

After discussing de Sousa's view of emotion in akrasia, I suggest that emotions be viewed as nonconceptual perceptions of value (see Tappolet 2000). It follows that they can render intelligible actions which are contrary to one's better judgment. An emotion can make one's action intelligible even when that action is opposed by one's all-things-considered judgment. Moreover, an akratic action prompted by an emotion may be more rational than following one's better judgement, for it may be the judgement and not the (...) perception which is in error. By contrast, "cool" akrasia is genuinely puzzling; it is not clear whether it exists. (shrink)

I argue that emotional feelings are not just bodily feelings, but also feelings directed towards things in the world beyond the bounds of the body, and that these feelings (feelings towards) are bound up with the way we take in the world in emotional experience.

This article was conceived as a sequel to “The Humean Theory of Motivation.” The paper addresses various challenges to the standard account of the explanation of intentional action in terms of desire and means-end belief, challenges that didn’t occur to me when I wrote “The Humean Theory of Motivation.” I begin by suggesting that the attraction of the standard account lies in the way in which it allows us to unify a vast array of otherwise diverse types of action explanation. (...) I go on to consider a range of other challenges to the standard account of the explanation of action: Rosalind Hursthouse’s challenge based on the possibility of what she calls “arational” actions (Hursthouse 1991); Michael Stocker’s challenge based on the idea that some explanations of action are nonteleological (Stocker 1981); Mark Platts’s challenge based on the idea that our evaluative beliefs can sometimes explain our actions all by themselves (Platts 1981); a voluntarist challenge based on the possibility of explaining actions by the exercise of self-control; and a challenge from Jonathan Dancy based on the idea that reasons can themselves sometimes explain actions all by themselves (Dancy 1994).

Consider a typical fear episode. You are strolling down a lonely mountain lane when suddenly a huge wolf leaps towards you. A number of different interconnected elements are involved in the fear you experience. First, there is the visual and auditory perception of the wild animal and its movements. In addition, it is likely that given what you see, you may implicitly and inarticulately appraise the situation as acutely threatening. Then, there are a number of physiological changes, involving a variety (...) of systems controlled by the autonomic nervous system. Your heart races, your breathing becomes strained and your start trembling. These changes are accompanied by an expression of fear on your face: your mouth opens and your eyes widen while you stare at the wolf. There is also a kind of experience that you undergo. You are likely to feel a sort of pang, something that might consist in the perception of the physiological changes you are going through. Moreover, a number of thoughts are likely to cross your mind. You might think that the wild beast is about to tear you into pieces and that you’ll never escape from this. In addition to this, your attention focuses on the wolf and its movement, as well as, possibly, ways of escaping or defending yourself. Last, but not least, your fear is likely to come with a motivation, such as an urge to run away or to strike back. Whatever the details of the story, it is clear that a typical emotion episode involves a number of different components. Roughly, these components are a) a sensory perception or more generally an informational component, b) a kind of appraisal, d) physiological changes, c) conscious feelings, d) cognitive and attentional processes, and e) an actiontendency or more generally a motivational component. One central question in the theory of emotion is which, if any, of these components, constitute the emotion.. (shrink)

Stocker intends this book to redress the common failures of contemporary moral philosophers to see the importance of emotions for their field. His aim is not merely to point out deficiencies in current thinking about emotions and their place in ethics, however. It is also to show how emotions are important for ethics. The book is divided into ten chapters, four of which are written in collaboration with Elizabeth Hegeman, an anthropologist and psychoanalyst. The first seven present criticisms of current (...) thinking and argue for some general theses about the way emotions are related to values. The last three examine specific emotions, notably, compassion, pity, pride, shame, and anger. They serve to substantiate the general theses about the way emotions are related to values that the first seven chapters promote. In this review I will concentrate on the material in these first seven chapters. Though some of it is jointly authored, I will for convenience' sake mostly refer just to Stocker as the author.

The motivational problem is the problem of understanding how we can have rational control over what we do. In the face of phenomena like weakness of the will, it is commonly thought that evaluation and reason can always remain intact even as we sever their connection with motivation; consequently, solving the motivational problem is thought to be a matter of figuring out how to bridge this inevitable gap between evaluation and motivation. I argue that this is fundamentally mistaken and results (...) in a conception of practical reason that is motivationally impotent. Instead, I argue, a proper understanding of evaluation and practical reason must include not only evaluative judgments but emotions as well. By analyzing the role of emotions in evaluation and the rational interconnections among emotions, desires, and evaluative judgments, I articulate a new conception of evaluation and motivation according to which there is a conceptual connection between them, albeit one that allows for the possibility of weakness of the will.

This paper constitutes a defence of an affective account of emotion. I begin by outlining the case for thinking that emotions are just feelings. I also suggest that emotional feelings are not reducible to other kinds of feelings, but rather form a distinct class of feeling state. I then consider a number of common objections that have been raised against affective accounts of emotion, including: (1) the objection that emotion cannot always consist only of feeling because some emotions - for (...) example, indignation and regret - necessarily have a cognitive component (say, the perception of a lost opportunity in the case of regret); (2) the objection that emotion cannot consist only of feeling because in order to explain how emotions have intentional objects we will have to recognise that emotion consists of cognition; and (3) the objection that emotion cannot consist only of feeling because emotion, but not feeling, can be variously assessed or evaluated. However, I demonstrate how an affective account of emotion might be successfully defended against all of the objections that are cited. (shrink)

This book has an ambitious aim—to make convincing the rejection of the hard and fast cognitive–conative divide currently so prevalent in philosophy of mind and moral psychology. Only such a rejection, Helm believes, can solve—or dissolve—the two major problems of practical reason. The ‘motivational problem’ is ‘a puzzle about the connection between our choosing something as the outcome of deliberation and our being motivated to pursue it’ (p. 1); the ‘deliberative problem’ concerns ‘how deliberation about value is possible’ (p. 11) (...) given that ‘our concept of value is pulled in seemingly opposed directions of objectivity and subjectivity’ (p. 200). Helm ‘suggests’ in chapter one, and argues with respect to particular attempts to solve these problems in later chapters, that acceptance of the cognitive-conative divide makes them quite intractable.

Peter Goldie’s The Emotions is a fascinating account distinguished by its originality and breadth. Throughout, the account is well grounded in sound common sense, as Goldie lets his careful and sensitive interpretation of the phenomena drive his theory rather than the other way around.
