Austen Clark presents a ground-breaking philosophical theory of sentience, drawing on and illuminating an abundance of scientific work on this subject. Sensation is one of the fundamental elements of consciousness, but has generally been assigned a lowly place in the mental hierarchy; Clark's rich, lucid, and original study restores it to its due prominence. A Theory of Sentience will be compelling reading for all who work on the interaction of mind and world.

Many philosophers doubt that one can provide any successful explanation of those qualities characterizing how things look, feel, or seem to a perceiving subject. To do so one would need to be able to explain qualitative facts in non-qualitative terms, and attempts to construct such an explanation seem doomed to failure. In this book Austen Clark presents an analysis of sensory qualities that refutes such skepticism and offers the possibility of a solution to the problem of qualia. Drawing on work in psychophysics, psychometrics, and sensory neurophysiology, he 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.

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 do so one would need to be able to explain qualitative facts in non-qualitative terms, and attempts to construct such an explanation seem doomed to failure. Austen Clark presents an analysis of sensory qualities that refutes such scepticism and offers the possibility of a solution to the problem of qualia. Drawing on work in psychophysics, psychometrics, and sensory neurophysiology, he analyses the character and defends the integrity of psychophysical explanations of qualitative facts, arguing that the structure of such explanations is sound and potentially successful. Clark gives a compact picture of that unified scheme that emerges from this project and sketches its potential reduction to neurophysiology. He does not claim to have a full explanation or a complete reduction of qualitative facts; rather, he shows that a solution to the problem of sensory qualities is possible, and outlines the structures within which it may yet be found.

Leading philosophers and scientists consider what conclusions about color can be drawn when the latest analytic tools are applied to the most sophisticated color science. Philosophers and scientists have long speculated about the nature of color. Atomists such as Democritus thought color to be "conventional," not real; Galileo and other key figures of the Scientific Revolution thought that it was an erroneous projection of our own sensations onto external objects. More recently, philosophers have enriched the debate about color by aligning the most advanced color science with the most sophisticated methods of analytical philosophy. In this volume, leading scientists and philosophers examine new problems with new analytic tools, considering such topics as the psychophysical measurement of color and its implications, the nature of color experience in both normal color-perceivers and the color blind, and questions that arise from what we now know about the neural processing of color information, color consciousness, and color language. Taken together, these papers point toward a complete restructuring of current orthodoxy concerning color experience and how it relates to objective reality. Kuehni, Jameson, Mausfeld, and Niederee discuss how the traditional framework of a three-dimensional color space and basic color terms is far too simple to capture the complexities of color experience. Clark and MacLeod discuss the difficulties of a materialist account of color experience. Churchland, Cohen, Matthen, and Westphal offer competing accounts of color ontology. Finally, Broackes and Byrne and Hilbert discuss the phenomenology of color blindness. Contributors Justin Broackes, Alex Byrne, Paul M. Churchland, Austen Clark, Jonathan Cohen, David R.
