- Austen Clark, How to Respond to Philosophers on Raw Feels.I address this talk to anyone who believes in the possibility of an informative empirical science about sensory qualities. Potentially this is a large audience. By "sensory quality" I mean those qualities manifest in various sensory experiences: color, taste, smell, touch, pain, and so on. We should include sensory modalities humans do not share, such as electro-reception in fish, echolocation in bats, or the skylight compass in birds. Those pursuing empirical science about this large domain might pursue it in the halls of experimental psychology, psycho-physics, psychometrics, psycho-physiology, sensory physiology, neuroscience, neuro-biology, comparative psychology, neuro-anatomy, and so on and on. These days even molecular genetics has kicked in with some notable recent contributions to the sequencing of genes for photopigments and for olfactory receptors. But to all those investigators in all those halls I bring bad news. Your discipline is _a priori_ impossible. Philosophers whom you do not know have uncovered _a priori_ proofs that empirical investigation which proceeds along the lines currently underway, or which will proceed along lines that are currently _imaginable_, does not, will not, and cannot explain the sensory qualities of experience. Or at least so they say. You might as well give up now.

In this paper I set out to solve the problem of how the world as we experience it, full of colours and other sensory qualities, and our inner experiences, can be reconciled with physics. I discuss and reject the views of J. J. C. Smart and Rom Harré. I argue that physics is concerned only to describe a selected aspect of all that there is – the causal aspect which determines how events evolve. Colours and other sensory qualities, lacking causal efficacy, are ignored by physics and cannot be predicted by physical theory. Even though physics is silent about sensory qualities, they nevertheless exist objectively in the world – in one sense of “objective” at least.

How could neural processes be associated with phenomenal consciousness? We present a way to answer this question by taking the counterintuitive stance that the sensory feel of an experience is not a thing that happens to us, but a thing we do: a skill we exercise. By additionally noting that sensory systems possess two important, objectively measurable properties, corporality and alerting capacity, we are able to explain why sensory experience possesses a sensory feel, but thinking and other mental processes do not. We are additionally able to explain why different sensory feels differ in the way they do.

I defend the possibility of a functional account of the intrinsic qualities of sensory experience against the claim that functional characterization can only describe such qualities to the level of isomorphism of relational structures on those qualities. A form sensory holism might be true concerning the phenomenal, and this holism would account for some antifunctionalist intuition evoked by inverted spectrum and absent qualia arguments. Sensory holism is compatible with the correctness of functionalism about the phenomenal.
Descartes is often thought to bifurcate sensory experience into two distinct cognitive components: the sensing of secondary qualities and the more or less intellectual perceiving of primary qualities. A closer examination of his analysis of sensory perception in the Sixth Replies and his treatment of sensory processing in the Dioptrics and Treatise on Man teIls a different story. I argue that Descartes offers a unified cognitive account of sensory experience according to which the senses and intellect operate together to produce a fundamentally imagistic representation of the world in both its primary and secondary quality aspects. At stake here is not only our understanding of the cognitive structure of sensory experience but the relation of sense and intellect more generally in the Cartesian mind. The deep bifurcation in the Cartesian mind is not between the sensory perception of primary and secondary qualities but between sensory perception and purely intellectual perception.
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.
In theorizing about perception, philosophers have often multiplied qualities. To perceptible qualities of external objects, like colors and shapes (‘sensible’ qualities), have been added qualities of experiences (‘sensory’ qualities) or of sense-data (‘sensational’ qualities). Start with sensory qualities. The phrase ‘sensory quality’ is not much in use these days, having lost out to ‘phenomenal character,’ ‘phenomenal property,’ ‘qualitative character,’ or ‘quale.’ But whatever sensory qualities are called, pinning them down is no easy matter.
