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.

Our reluctance to demystify grief is a sign of the distinctive obligation and discomfort that people feel towards those who have died. These feelings, however, are instructive about the nature of grief. As a vehicle of a living person’s relation to the dead, grief is mysterious—and we are rightly reluctant to take that mystery away. But grief is not to be avoided by philosophy on that account. I defend a less Romantic view of grief, in which a grieving person’s experience (...) of “normal” grief: 1) is felt to require an objectively recognized loss; 2) is felt to be dedicated to that lost object; 3) seems to most people to be something that she ought to feel; and 4) probably ought not to be medicalized, nor consequently medicated. This view of grief affords an understanding and appreciation of this rather special and important emotion without reducing its mystery. (shrink)

In this paper, we develop a fresh understanding of the sense in which emotions are evaluations. We argue that we should not follow mainstream accounts in locating the emotion–value connection at the level of content and that we should instead locate it at the level of attitudes or modes. We begin by explaining the contrast between content and attitude, a contrast in the light of which we review the leading contemporary accounts of the emotions. We next offer reasons to think (...) that these accounts face substantial problems since they locate the link emotions bear to values at the level of content. This provides the incentive to pursue an alternative approach according to which emotions qualify as evaluations because they are specific types of attitudes, an approach we substantiate by appealing to felt bodily stances. We conclude by considering two reasons why this approach may be resisted; they respectively pertain to the alleged impossibility of drawing the attitude–content contrast in the case of the emotions and to the suspicion that so doing raises qualia-related worries.

In "Upheavals of Thought", Martha Nussbaum offers a theory of the emotions. She argues that emotions are best conceived as thoughts, and she argues that emotion-thoughts can make valuable contributions to the moral life. She develops extensive accounts of compassion and erotic love as thoughts that are of great moral import. This paper seeks to elucidate what it means, for Nussbaum, to say that emotions are forms of thought. It raises critical questions about her conception of the structure of emotion, (...) and about her conception of compassion, in particular. Finally, the paper seeks to show how analyzing the structure, as well as the moral value, of the emotions ultimately requires entering the realm of religious ethics. (shrink)

In “The Child’s Relations with Others,” Merleau-Ponty argues that certain early experiences are jointly owned in that they are numerically single experiences that are nevertheless given to more than one subject (e.g., the infant and caregiver). Call this the “joint ownership thesis” (JT). Drawing upon both Merleau-Ponty’s phenomenological analysis, as well as studies of exogenous attention and mutual affect regulation in developmental psychology, I motivate the plausibility of JT. I argue that the phenomenological structure of some early infant–caregiver dyadic exchanges (...) is best described as involving joint subjects. From birth, some experiences are constitutively social in that certain phenomenal states, such as the positive emotions that arise within these early exchanges, are jointly owned. Along the way, I consider a possible objection. I conclude by considering the explanatory significance of adopting JT. (shrink)

Existing scientific concepts of group or shared or collective emotion fail to appreciate several elements of collectivity in such emotions. Moreover, the idea of shared emotions is threatened by the individualism of emotions that comes in three forms: ontological, epistemological, and physical. The problem is whether or not we can provide a plausible account of ?straightforwardly shared? emotions without compromising our intuitions about the individualism of emotions. I discuss two philosophical accounts of shared emotions that explain the collectivity of emotions (...) in terms of their intentional structure: Margaret Gilbert's plural subject account, and Hans Bernhard Schmid's phenomenological account. I argue that Gilbert's view fails because it relegates affective experience into a contingent role in emotions and because a joint commitment to feel amounts to the creation of a feeling rule rather than to an emotion. The problems with Schmid's view are twofold: first, a phenomenological fusion of feelings is not necessary for shared emotions and second, Schmid is not sensitive enough to different forms of shared concerns. I then outline my own typology that distinguishes between weakly, moderately, and strongly shared emotions on the basis of the participants? shared concerns of different degree of collectivity, on the one hand, and the synchronization of their emotional responses, on the other hand. All kind of shared emotions in my typology are consistent with the individualism of emotions, while the question about ?straightforward sharing? is argued to be of secondary importance. (shrink)

Grief is not a kind of feeling, or a kind of judgement, or a kind of perception, or any kind of mental state or event the identity of which can be adequately captured at a moment in time. Instead, grief is a kind of process; more specifically, it is a complex pattern of activity and passivity, inner and outer, which unfolds over time, and the unfolding pattern over time is explanatorily prior to what is the case at any particular time. (...) The pattern of a particular grieving is best understood and explained through a narrative account, and not merely through a causal account, for narrative accounts in such cases have powerful explanatory, revelatory, and expressive powers which causal accounts lack. Although I will not argue for it here, I believe that this view of grief can be generalised to other kinds of emotion. If this is so, then many philosophical accounts of emotion are at fault in identifying emotion with a kind of mental state or event. (shrink)

Two years after the death of his small son, Ralph Waldo Emerson famously wrote of the experience, "I cannot get it nearer to me" (CW 3:29). Most readers have been troubled by this remark, reading it as a sign that Emerson's relationship to grief and even to his son was disturbingly oblique, and the predominant response has been that it demonstrates he was detached, cold, and disconnected in the service of his transcendental philosophy.1 Such a response is grounded in the (...) tacit assumption that philosophy seems to be, or to call for, some intellectually grounded transcendence of the personal, whether the personal is whimsical or fatal. Emerson himself worried at times that he was too cold, too intellectual, even as .. (shrink)

Philosophical cognitivists have argued for more than four decades that emotions are special types of judgments. Anti-cognitivists have provided a series of counterexamples aiming to show that identifying emotions with judgments overintellectualizes the emotions. I provide a novel counterexample that makes the overintellectualization charge especially vivid. I discuss neurophysiological evidence to the effect that the fear system can be activated by stimuli the subject is unaware of seeing. To emphasize the analogy with blind sight , I call this phenomenon blind (...) fright . Cognitivists may reply that blindfright is nothing but an unconscious judgment subcortically elicited. This reply is in line with the strategy commonly employed by cognitivists against their critics. I call it the Elastic Strategy, because it consists of ‘stretching’ the notion of judgment in order to accommodate counterexamples. This strategy, I argue, turns cognitivism into a theory that is at worst unfalsifiable and at best trivially true. The final portion of my article aims to rescue cognitivism from the damage done by the Elastic Strategy. I distinguish three varieties of cognitivism, one concerned with what emotions essentially are (Constitutive Cognitivism), one concerned with what causes emotions (Etiological Cognitivism) and one concerned with what emotions represent (Representational Cognitivism). I conclude that what cognitivism has to offer to emotion theory are primarily insights concerning the causes and representational content of emotions. The constitutive identification of emotions with judgments, on the other hand, does more harm than good. (shrink)

Donald Gustafson has argued that grief centres on a combination of belief and desire:The belief that the subject has suffered an irreparable loss.The desire that this should not be the case.And yet, as Gustafson points out, if the belief is true, the desire cannot be satisfied. Gustafson takes this to show that grief inevitably implies an irrational conflict between belief and desire.I offer a partial defence of grief against Gustafson's charge of irrationality. My defence rests on two elements. First, I (...) offer an alternative model of emotion, which presents emotions as complex episodes, initiated by emotional appraisals. Secondly, I appeal to John Bowlby's account of grief to argue that grief involves two forms of sadness (anguish and desolation) which Gustafson's analysis runs together. I concede that anguish does characteristically involve an element of irrationality. But the irrationality of anguish does not arise from an apparently gratuitous clash between belief and desire, but from a conflict between emotion and belief—a form of irrationality that is both familiar and easily explained. Moreover, desolation need not involve any irrationality. (shrink)

My concern in this paper is with the intentionality of emotions. Desires and cognitions are the traditional paradigm cases of intentional attitudes, and one very direct approach to the question of the intentionality of emotions is to treat it as sui generis—as on a par with the intentionality of desires and cognitions but in no way reducible to it. A more common approach seeks to reduce the intentionality of emotions to the intentionality of familiar intentional attitudes like desires and cognitions. (...) In this paper, I argue for the sui generis approach. (shrink)

Emotions, I will argue, involve two kinds of feeling: bodily feeling and feeling towards. Both are intentional, in the sense of being directed towards an object. Bodily feelings are directed towards the condition of one's body, although they can reveal truths about the world beyond the bounds of one's body – that, for example, there is something dangerous nearby. Feelings towards are directed towards the object of the emotion – a thing or a person, a state of affairs, an action (...) or an event; such emotional feelings involve a special way of thinking of the object of the emotion, and I draw an analogy with Frank Jackson's well-known knowledge argument to show this. Finally, I try to show that, even if materialism is true, the phenomenology of emotional feelings, as described from a personal perspective, cannot be captured using only the theoretical concepts available for the impersonal stance of the sciences.

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)

There has been much recent philosophical discussion concerning the relationship between emotion and feeling. However, everyday talk of 'feeling' is not restricted to emotional feeling and the current emphasis on emotions has led to a neglect of other kinds of feeling. These include feelings of homeliness, belonging, separation, unfamiliarity, power, control, being part of something, being at one with nature and 'being there'. Such feelings are perhaps not 'emotional'. However, I suggest here that they do form a distinctive group; all (...) of them are ways of 'finding ourselves in the world'. Indeed, our sense that there is a world and that we are 'in it' is, I suggest, constituted by feeling. I offer an analysis of what such 'existential feelings' consist of, showing how they can be both 'bodily feelings' and, at the same time, part of the structure of intentionality. (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.

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.
