Where do we draw the line between the physiology of color perception and the philosophy of the language of color perception? I think of those contemporary philosophers who have devoted themselves to research on the "mind." Hasn't this concept between replaced by a far more satisfying vocabulary of neurophysiology outside of philosophy, and the philosophy of language inside of philosophy? This is not a mere boundary dispute. Rather, the implication is that once the line is drawn one category or discourse is rendered otiose. I want to spend a little more time on this. What is the state of the art in cogntiive psychology on color perception? I'll see if I can find this out.
