Various prominent theories of pain assume that it is pain’s biological function to inform organisms about damage to their bodies. I argue that this is a mistake. First, there is no biological evidence to support the notion that pain was originally selected for its informative capacities, nor that it currently contributes to the fitness of organisms in this specific capacity. Second, neurological evidence indicates that modulating mechanisms in the nociceptive system systematically prevent pain from serving a primarily informative role. These (...) considerations threaten to undermine standard perceptual and representational accounts of pain. (shrink)

I argue that experiences can have microphenomenal structures, where the macrophenomenal properties we introspect are realized by non-introspectible microphenomenal properties. After explaining what it means to ascribe a microstructure to experience, I defend the thesis against its principal philosophical challenge, discuss how the thesis interacts with other philosophical issues about experience, and consider our prospects for investigating the microphenomenal realm.

While seeking novel food sources to feed the increasing population of the globe, several alternatives have been discussed, including algae, fungi or in vitro meat. The increasingly propagated usage of farmed insects for human nutrition raises issues regarding food safety, consumer information and animal protection. In line with law, insects like any other animals must not be reared or manipulated in a way that inflicts unnecessary pain, distress or harm on them. Currently, there is a great need for research in (...) the area of insect welfare, especially regarding species-specific needs, health, farming systems and humane methods of killing. Recent results from neurophysiological, neuroanatomical and behavioral sciences prompt caution when denying consciousness and therefore the likelihood of presence of pain and suffering or something closely related to it to insects. From an animal protection point of view, these issues should be satisfyingly solved before propagating and establishing intensive husbandry systems for insects as a new type of mini-livestock factory farming.

The paper argues that pain is not a good counter-example to the privation theory of evil. Objectors to the privation thesis see pain as too real to be accounted for in privative terms. However, the properties for which pain is intuitively thought of as real, i.e. its localised nature, intensity, and quality are features of the senso-somatic aspect of pain. This is a problem for the objectors because, as findings of modern science clearly demonstrate, the senso-somatic aspect of pain is (...) neurologically and clinically separate from the emotional-psychological aspect of suffering. The intuition that what seems so real in pain is also the source of pain’s negative value thus falls apart. As far as the affective aspect of pain, i.e. ”painfulness’ is concerned, it cannot refute the privation thesis either. For even if this is indeed the source of pain’s badness, the affective aspect is best accounted for in privative terms of loss and negation. The same holds for the effect of pain on the aching person. (shrink)

A movement dedicated to applying neuroscience to traditional philosophical problems and using philosophical methods to illuminate issues in neuroscience began about twenty-five years ago. Results in neuroscience have affected how we see traditional areas of philosophical concern such as perception, belief-formation, and consciousness. There is an interesting interaction between some of the distinctive features of neuroscience and important general issues in the philosophy of science. And recent neuroscience has thrown up a few conceptual issues that philosophers are perhaps best trained (...) to deal with. After sketching the history of the movement, we explore the relationships between neuroscience and philosophy and introduce some of the specific issues that have arisen. (shrink)

In “What is it like to be boring and myopic?” Kathleen Akins offers an interesting, empirically driven, argument for thinking that there is nothing that it is like to be a bat. She suggests that bats are “boring” in the sense that they are governed by behavioral scripts and simple, non-representational, control loops, and are best characterized as biological automatons. Her approach has been well received by philosophers sympathetic to empirically informed philosophy of mind. But, despite its influence, her work (...) has not met with any critical appraisal. -/- It is argued that a reconsideration of the empirical results shows that bats are not boring automatons, driven by short input-output loops, instincts, and reflexes. Grounds are provided for thinking that bats satisfy a range of philosophically and scientifically interesting elaborations of the general idea that consciousness is best understood in terms of representational functions. A more complete examination of bat sensory capabilities suggests there is something that it is like after all. -/- The discussion of bats is also used to develop an objection to strongly neurophilosophical approaches to animal consciousness.

What is the relationship between pain and the body? I claim that pain is best explained as a type of personal experience and the bodily response during pain is best explained in terms of a type of mechanical neurophysiologic operation. I apply the radical philosophy of identity theory from philosophy of mind to the relationship between the personal experience of pain and specific neurophysiologic mechanism and argue that the relationship between them is best explained as one of type identity. Specifically, (...) pain is a specific type of personal experience identical to a specific type of allostatic stress response comprised of interdependent nervous, endocrine and immune mechanical operations.

Aquaculture is the fastest growing animal-production sector in the world. This leads to the question how we should guarantee fish welfare. Implementing welfare standards presupposes that we know how to weigh, define, and measure welfare. While at first glance these seem empirical questions, they cannot be answered without ethical reflection. Normative assumptions are made when weighing, defining, and measuring welfare. Moreover, the focus on welfare presupposes that welfare is a morally important concept. This in turn presupposes that we can define (...) the capacities of fish, which is an empirical undertaking that informs and is informed by ethical theories about the moral status of animals. In this article we want to illustrate the need for a constant interaction between empirical scientific research and ethics, in which both fields of research make their own contribution. This is not a novel claim. However, the case of fish sheds new light on this claim, because regarding fish there is still much empirical uncertainty and there is a plurality of moral views on all levels. Therefore, we do not only want to show the necessity of this interaction, but also the added value of a cooperation between ethicists and empirical scientists, such as biologists, physiologists, and ethologists. We demonstrate this by considering the different steps in the process of reflection about and implementation of fish welfare. (shrink)

Pain asymbolics feel pain, but act as if they are indifferent to it. Nikola Grahek argues that such patients present a clear counterexample to motivationalism about pain. I argue that Grahek has mischaracterized pain asymbolia. Properly understood, asymbolics have lost a general capacity to care about their bodily integrity. Asymbolics’ indifference to pain thus does not show something about the intrinsic nature of pain ; it shows something about the relationship between pains and subjects, and how that relationship might break (...) down. I explore the consequences of such a view for both motivationalism and the categorization of pain asymbolia as a syndrome, arguing for a close link between asymbolia and various forms of depersonalization.

Pain is the most prominent member of a class of sensations known as bodily sensations, which includes itches, tickles, tingles, orgasms, and so on. Bodily sensations are typically attributed to bodily locations and appear to have features such as volume, intensity, duration, and so on, that are ordinarily attributed to physical objects or quantities. Yet these sensations are often thought to be logically private, subjective, self-intimating, and the source of incorrigible knowledge for those who have them. Hence there appear to (...) be reasons both for thinking that pains (along with other similar bodily sensations) are physical objects or conditions that we perceive in body parts, and for thinking that they are not. This apparent paradox is one of the main reasons why philosophers are especially interested in pain. One increasingly popular but still controversial way to deal with this apparent paradox is to defend a perceptual or representational view of pain, according to which feeling pain is in principle no different from undergoing other standard perceptual processes like seeing, hearing, touching, etc. But there are many who think that pains are not amenable to such a treatment. Although it was the treatment of pain as a sensory-discriminative experience that had dominated the philosophical discussions throughout most of the twentieth century, attention to pains’ affective-motivational dimension has gained prominence in recent years.

Which nonhuman animals experience conscious pain?1 This question is central to the debate about animal welfare, as well as being of basic interest to scientists and philosophers of mind. Nociception—the capacity to sense noxious stimuli—is one of the most primitive sensory capacities. Neurons functionally specialized for nociception have been described in invertebrates such as the leech Hirudo medicinalis and the marine snail Aplysia californica (Walters 1996). Is all nociception accompanied by conscious pain, even in relatively primitive animals such as Aplysia, (...) or is it the case, as some philosophers continue to maintain, that conscious experiences are the exclu- sive province of human beings? What philosophical and scientific resources are presently available for assessing claims lying between these extremes? (shrink)

Over the past three decades, philosophy of science has grown increasingly “local.” Concerns have switched from general features of scientific practice to concepts, issues, and puzzles specific to particular disciplines. Philosophy of neuroscience is a natural result. This emerging area was also spurred by remarkable recent growth in the neurosciences. Cognitive and computational neuroscience continues to encroach upon issues traditionally addressed within the humanities, including the nature of consciousness, action, knowledge, and normativity. Empirical discoveries about brain structure and function suggest (...) ways that “naturalistic” programs might develop in detail, beyond the abstract philosophical considerations in their favor. -/- The literature distinguishes “philosophy of neuroscience” and “neurophilosophy.” The former concerns foundational issues within the neurosciences. The latter concerns application of neuroscientific concepts to traditional philosophical questions. Exploring various concepts of representation employed in neuroscientific theories is an example of the former. Examining implications of neurological syndromes for the concept of a unified self is an example of the latter. In this entry, we will assume this distinction and discuss examples of both. (shrink)

Many traditional attempts to show that nonhuman animals are deserving of moral consideration have taken the form of an argument by analogy. However, arguments of this kind have had notable weaknesses and, in particular, have not been able to convince two kinds of skeptics. One of the most important weaknesses of these arguments is that they fail to provide theoretical justifications for why particular physiological similarities should be considered relevant. This paper examines recent empirical research on pain and, in particular, (...) explores the implications of the dissociation between the sensory and the affective pain pathways. It is argued that these results show that the belief that nonhuman animals experience pain in a morally relevant way is reasonable, though not certain. It is further argued that the proposal to explore the relationship between consciousness and various forms of learning challenges the aforementioned skeptics to provide more physiological details for their claims that nonhuman mammals are probably not conscious.

The object of the present work is to rectify the neglect that pleasure and displeasure have been suffering from in the philosophy of mind, and to give an account of pleasure and displeasure which reveals a striking degree of unity and theoretical tractabiliy underlying the diverse phenomena: a representationalist account.

This paper discusses recent neuroscientific research that indicates a solution for what we label the ''causal problem'' of pain qualia, the problem of how the brain generates pain qualia. In particular, the data suggest that pain qualia naturally supervene on activity in a specific brain region: the anterior cingulate cortex (ACC). The first section of this paper discusses several philosophical concerns regarding the nature of pain qualia. The second section overviews the current state of knowledge regarding the neuroanatomy and physiology (...) of pain processing. The third section highlights the recent research by Rainville et al. [(1997) Pain affect encoded in human anterior cingulate but not somatosensory cortex, Science, 277, 968-971], which suggests that pain affect is encoded in the ACC. The final section of the paper spells out exactly how these data affect the causal problem of pain qualia. (shrink)

In Why pains are not mental objects Guy Douglasrightly argues that pains are modes rather than objects ofperceptions or sensations. In this paper I try to go a stepfurther and argue that there are circumstances when pains canbecome objects even while they remain modes of experience.By analysing cases of extreme pain as presented by Scarry,Sartre, Wiesel, Grahek and Wall, I attempt to show thatintense physical pain may evolve into a force that, likeimagination, can make our most intense state of experiencebecome (...) a mental object. I shall finally argue that, thoughextreme pains cannot serve as paradigm cases, they do showthe general importance of taking pain states to be objects. (shrink)

Pains are subject to obvious, well-documented, and striking top-down influences. This is in stark contrast to visual perception, where the debate over cognitive penetrability tends to revolve around fairly subtle experimental effects. Several authors have recently taken up the question of whether top-down effects on pain count as cognitive penetrability, and what that might show us about traditional debates. I review some of the known mechanisms for top-down modulation of pain, and suggest that it reveals an issue with a relatively (...) neglected part of the cognitive penetrability literature. Much of the debate inherits Pylyshyn’s stark contrast between transducers and cognition proper. His distinction grew out of his running fight with Gibson, and is far too strong to be defensible. I suggest that we might therefore view top-down influences on pain as a species of transducer calibration. This provides a novel but principled way to distinguish between several varieties of top-down effect according to their architectural features. (shrink)

Discussions concerning the modularity of the pain system have been focused on questions regarding the cognitive penetrability of pain mechanisms. It has been claimed that phenomena such as placebo analgesia demonstrate that the pain system is cognitively penetrated; therefore, it is not encapsulated from central cognition. However, important arguments have been formulated which aim to show that cognitive penetrability does not in fact entail a lack of modularity of the pain system. This paper offers an alternative way to reject the (...) modularity of the pain system, which is independent from, but consistent with, the presence of cognitive penetration. It is proposed that, given the current knowledge regarding the functioning and the structure of the pain system, there are good reasons to accept that certain central cognitive mechanisms are part of the pain system. It is argued that such a ‘cognitive constitution’ of the pain system entails that the pain system is not modular. (shrink)

Unresponsive wakefulness syndrome is a disorder of consciousness wherein a patient is awake, but completely non-responsive at the bedside. However, research has shown that a minority of these patients remain aware, and can demonstrate their awareness via functional neuroimaging; these patients are referred to as having ‘cognitive motor dissociation’. Unfortunately, we have little insight into the subjective experiences of these patients, making it difficult to determine how best to promote their well-being. In this paper, I argue that the capacity to (...) experience pain or pleasure is a key component of well-being for these patients. While patients with unresponsive wakefulness syndrome are believed to be incapable of experiencing pain or pleasure, I argue that there is evidence to support the notion that CMD patients likely can experience pain and pleasure. I analyze current neuroscientific research into the mechanisms of pain experience in patients with disorders of consciousness, and provide an explanation for why CMD patients likely can experience physical pain. I then do the same for physical pleasure. I conclude that providing these patients with pleasurable experiences, and avoiding subjecting them to pain, are viable means of promoting their well-being.

The Mind-Brain Identity Theory lived a short life as a respectable philosophical position in the late 1950s, until Hilary Putnam developed his famous argument on the multiple realizability of mental states. The argument was, and still is, taken as the definitive demonstration of the falsity of Identity Theory and the foundation on which contemporary functionalist computational cognitive science was to be grounded. In this paper, in the wake of some contemporary philosophers, we reopen the case for Identity Theory and offer (...) a solution to the problem of multiple realizabilty. The solution is based on the necessity, at the time of establishing identity relations, of appealing to the notions of “homology” and “analogy” developed in the nineteenth century by Richard Owen. We also suggest that these notions are useful in order to correct certain shortcomings of some recent attempts at rebutting the Multiple Realizability argument. (shrink)

Adverbialism, broadly construed, is the thesis that pains (and other sensations) are modes of awareness, and objectualism, broadly construed, is the thesis that pains are objects of awareness. Why are we inclined to say that pains are modes of awareness and yet also inclined to say that they are objects of awareness? Each inclination leads to an account of pain that seems to be incompatible with the other. If adverbialism is correct, it would seem that objectualism is mistaken (and vice (...) versa). And yet each inclination is sufficiently well grounded that neither seems reasonably rejectable. It will not do to present each theory with greater and greater sophistication on the assumption that if it is correct the other must be mistaken. What we must do is give an account of pain that shows how it is possible to retain the central insights of both adverbialism and objectualism. I propose to do that in this paper, mounting a case for the claim that the most plausible view of pain is one that combines adverbialism and objectualism. (shrink)

Arguments over whether emotions and moods are feelings have demonstrated confusion over the concept of a feeling and, in particular, what it is that feelings can—and cannot—do. I argue that the causal and explanatory roles we assign emotions and moods in our theories are inconsistent with their being feelings. Sidestepping debates over the natures of emotions and moods I frame my arguments primarily in terms of what it is emotions, moods and feelings do. I provide an analysis that clarifies the (...) role feelings can play in our psychology that is consistent with current psychological and neurological data. (shrink)

This paper investigates the status of the purported explanatory gap between pain phenomena and natural science, when the “gap” is thought to exist due to the special properties of experience designated by “ qualia ” or “the pain quale” in the case of pain experiences. The paper questions the existence of such a property in the case of pain by: looking at the history of the conception of pain; raising questions from empirical research and theory in the psychology of pain; (...) considering evidence from the neurophysiological systems of pain; investigating the possible biological role or roles of pain; and considering methodological questions of the comparable status of the results of the sciences of pain in contrast to certain intuitions underpinning “the explanatory gap” in the case of pain. Skepticism concerning the crucial underlying intuitions seems justified by these considerations. (shrink)

According to a long-standing belief, introspection provides privileged access to the mind, while objective methods, which we denote as “extrospection”, suffer from basic epistemic deficits. Here we will argue that neither an introspective privilege exists nor does extrospection suffer from such deficits.We will focus on two entailments of an introspective privilege: first, such a privilege would require that introspective evidence prevails in cases of conflict with extrospective information. However, we will show that this is not the case: extrospective claims can (...) prevail in cases of conflict. These conflicts are resolved by an inference to the explanation that best accounts for the available evidence. This explanation may speak in favor of extrospection.Second, given an introspective privilege, the development of extrospective measurement techniques should be restricted by the accuracy of introspective reports. We will argue that this problem is part of a more general issue that comes up with the establishment of measurement in the natural sciences. We will identify three strategies that have proven successful in dealing with the problem in the natural sciences. It will turn out that all these strategies are available for extrospective measurement as well. Consequently, the insufficiencies of introspective reports do not impose a limit on the accuracy of extrospective measurement methods.We conclude that neither an introspective privilege nor basic extrospective deficits exist. This does not mean that extrospection will ever replace introspection. Rather, both approaches provide independent and indispensable forms of epistemic access to the mind. (shrink)

Philosophers have recently argued that since there are people who are blind, but don't know it, and people who echolocate, but don't know it, conscious introspection is highly unreliable. I contend that a second look at Anton's syndrome, human echolocation, and ‘facial vision’ suggests otherwise. These examples do not support skepticism about the reliability of introspection.

When looking for an account that explains how pain changes consciousness, one finds that most studies in the phenomenology of pain focus either on the outcome of the change, or on how it affects the self, as a conscious object, and the self’s experiences in the world of objects. This paper focuses on the mechanism of consciousness, exploring the nature of the change that pain creates in consciousness and how exactly that change occurs. The paper provides a systematic, phenomenological inquiry (...) in three phases: one identifies three essential attributes of consciousness, another identifies three essential attributes of pain, and a third analyses the outcome of the integration between both sets of attributes. The paper demonstrates how the change wrought by pain on the self, as a conscious object, allows the self to breach its boundaries as an object, and experience being a non-object, even if only in part and temporarily.
