Why is pain the opposite of pleasure? Several theories of pleasure and pain have substantial difficulty explaining this basic feature. Theories according to which pleasure and pain are individual sensations or features of sensations have particular difficulty, since it is difficult to understand how pairs of sensations could be opposites. Some philosophers argue that the pain is the opposite of pleasure because pain and pleasure are fundamentally a matter of desire and aversion, and desire and aversion are clear opposites. I argue that the structure of desire and aversion does not correspond to that of pleasure and pain. I propose that pleasure and pain are opposites because pleasure is good and pain is bad, and good and bad are clear opposites. I show that this view explains the structure of opposition of pleasure and pain, and I answer several objections.

Review of Murat Aydede's edited collection, *Pain: New Essays on Its Nature and the Methodology of Its Study".

The aim of this paper is to show that the empirical and conceptual constraints arising from the scientific research on pain phenomena should be taken into account in philosophical discussions concerning the nature and function of pain; otherwise, there is a good chance that philosophers will advocate too simplistic, confused or even outrightly mistaken theories or conceptions of pain. In order to prove this point, one of the most influential philosophical theories of pain—the so-called perceptual view of pain—is put to scrutiny in the light of the psychological, clinical and neurophysiological data coming from the field of pain research. More specifically, these data are presented in such a way as to show that the sensory quality or sensory aspect of pain is, contrary to the objectivistic claims of the perceptual view of pain, a necessary component of our total pain experience.

What follows raises objections to some arguments that claimthat a principle of applicability of ordinary pain talkconstrains developments in the pain sciences. A more apt pictureof lay use of pain language shows its non-theoretic character.Since instrumentalism and eliminativism are philosophical viewsabout the status of theories of pain, neither is a threatto clinical use of standard pain lingo. Perfected pain theoryis likely to enhance and improve pain language in clinicalsettings, should such theory find its way into popular ideasand talk of pain.

This paper develops an instrumentalistic argumentagainst an eliminativist approach to using the folkconcept of pain in clinical medicine and draws someimplications for biomedical theories of pain. Thepaper argues that the folk concept of pain plays afundamental role in several aspects of clinicalmedicine, including the diagnosis and treatment ofdiseases and symptoms, relieving human suffering, andthe doctor-patient relationship. Since clinicians mustbe able to apply biomedical theories of pain inmedical practice, these theories should not stray toofar from pain's clinical realities. Biomedicaltheories of pain should at least incorporate an analogof the folk concept of pain, even if this concept isrevised in light of scientific advances.

The ordinary conception of pain has two major threads that are in tension with each other. It is this tension that generates various puzzles in our philosophical understanding of pain. According to one thread, pain is something that we locate in body parts using sentences such as..

This paper examines pain states (and other intransitive bodily sensations) from the perspective of the problems they pose for pure informational/representational approaches to naturalizing qualia. I start with a comprehensive critical and quasi-historical discussion of so-called Perceptual Theories of Pain (e.g., Armstrong, Pitcher), as these were the natural predecessors of the more modern direct realist views. I describe the theoretical backdrop (indirect realism, sense-data theories) against which the perceptual theories were developed. The conclusion drawn is that pure representationalism about pain in the tradition of direct realist perceptual theories (e.g., Dretske, Tye) leaves out something crucial about the phenomenology of pain experiences, namely, their affective character. I touch upon the role that introspection plays in such representationalist views, and indicate how it contributes to the source of their trouble vis-à-vis bodily sensations. The paper ends by briefly commenting on the relation between the affective/evaluative component of pain and the hedonic valence of emotions.
