Many philosophers doubt that one can provide any successful explanation of sensory qualities - of how things look, feel, or seem to a perceiving subject. To provide such an explanation, one would need to explain qualitative facts in non-qualitative terms. Attempts to construct such explanations have seemed, in principle, doomed. Austen Clark examines the strategy used in psychophysics, psychometrics, and sensory neurophysiology to explain qualitative facts. He argues that this strategy could succeed: its structure is sound, and it can answer (...) the various philosophical objections lodged against it. On this basis Professor Clark presents an analysis of senosry qualities that offers the possibility of explaining at least some qualia, and he sketches how this scheme might eventually reduce to neurophysiology. If he is correct, we are not doomed to an eternity of mere acquaintance with our qualia. (shrink)

According to the increasingly popular perceptual/representational accounts of pain (and other bodily sensations such as itches, tickles, orgasms, etc.), feeling pain in a body region is perceiving a non-mental property or some objective condition of that region, typically equated with some sort of (actual or potential) tissue damage. In what follows I argue that given a natural understanding of what sensory perception requires and how it is integrated with (dedicated) conceptual systems, these accounts are mistaken. I will also examine the (...) relationship between perceptual views and two (weak and strong) forms of representationalism about experience. I will argue that pains pose very serious problems for strong representationalism as well. (shrink)

The unpleasantness of pain motivates action. Hence many philosophers have doubted that it can be accounted for purely in terms of pain’s possession of indicative representational content. Instead, they have explained it in terms of subjects’ inclinations to stop their pains, or in terms of pain’s imperative content. I claim that such “noncognitivist” accounts fail to accommodate unpleasant pain’s reason-giving force. What is needed, I argue, is a view on which pains are unpleasant, motivate, and provide reasons in virtue of (...) possessing content that is indeed indicative, but also, crucially, evaluative.

Pain, crucially, is unpleasant and motivational. It can be awful; and it drives us to action, e.g. to take our weight off a sprained ankle. But what is the relationship between pain and those two features? And in virtue of what does pain have them? Addressing these questions, Colin Klein and Richard J. Hall have recently developed the idea that pains are, at least partly, experiential commands—to stop placing your weight on your ankle, for example. In this paper, I reject (...) their accounts. Against Klein, I use dissociation cases to argue that possession of ‘imperative content’ cannot wholly constitute pain. Against them both, I further claim that possession of such content cannot even constitute pain’s unpleasant, motivational aspect. For, even if it were possible to specify the relevant imperative content—which is far from clear—the idea of a command cannot bear the explanatory weight Klein and Hall place on it. (shrink)

_Naming and Necessity_ has had a great and increasing influence. It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of naming, and of identity. This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here reissued in a newly corrected form with a new preface by the author. If there is such a thing as essential reading in metaphysics, or in philosophy of language, this is (...) it. (shrink)

The senses, or sensory modalities, constitute the different ways we have of perceiving the world, such as seeing, hearing , touching, tasting, and smelling. But what makes the senses different? How many senses are there? How many could there be? Wha t interaction takes place between the senses? This introduction is a guide to thinking about these questions.

A transcript of three lectures, given at Princeton University in 1970, which deals with (inter alia) debates concerning proper names in the philosophy of language.

Drawing on work in psychophysics, psychometrics, and sensory neurophysiology, Clark analyzes the character and defends the integrity of psychophysical explanations of qualitative facts, arguing that the structure of such explanations is sound and potentially successful.

When you suffer a pain are you suffering a sensation? An emotion? An aversion? Pain typically has all three components, and others too. There is indeed a distinct sensory system devoted to pain, with its own nociceptors and pathways. As a species of somesthesis, pain has a distinctive sensory organization and its own special sensory qualities. I think it is fair to call it a distinct sensory modality, devoted to nociceptive somesthetic discrimination. But the typical pain kicks off other processes (...) too. For one it can grab your attention in a distinctive way, alerting you to its presence and sometimes obliging you to focus attention on the damaged member. Intense pain can eliminate your ability to think about anything else. Pain typically has direct and immediate motivational consequences: one wants it to stop, has an incentive to do whatever one can to reduce it, and is gratified by its termination. As these desires and motives collide with neural reality, emotional components of mental anguish, anxiety, and dread arise. The suffering involved in suffering from pain has multiple strands: it is not just the painfulness of the sensation, or the frustration of the desire that it end, but also the anguish over the possibility that it will never end, and the impossibility, if the pain is sufficiently intense, of focusing one’s attention on anything else.
