People are taught in school that a sufficient response to the question "how do we hear things?" is to talk about sound waves, the shape of the outer ear, the tympanic membrane, malleus, incus, stapes, cochlea, etc. At some point you arrive at: "and then the brain processes the signal in the auditory cortex and stuff." We have become accustomed to this sort of answer, but it really doesn't even begin to answer the real (and interesting) question: why does all that processing result in the felt experience of hearing, rather than the nervous system just bubbling up and causing a behavior with no feelings? Why does it "feel" that way and not some other way? Is there a different kind of hearing that "feels" fundamentally different from our experience?
My point is that, we are closer to explaining some functional aspects of the brain, but when it comes to explaining the nature and character of our qualitative experience, we are at the same place as the ancient Eastern philosophers - we've really gotten nowhere.
