This article contains three simple questions which I want to see answered. To organize the discussion, I'm creating a thread for each question, so people with an answer can state it or link to it. If you link, please provide a brief summary of your answer here as well.
First question: Where is color?
I see a red apple. The redness, I grant you, is not a property of the thing that grew on the tree, the object outside my skull. It's the sensation or perception of the apple which is red. However, I do insist that something is red. But if reality is nothing but particles in space, and empty space is not red, and the particles are not red, then what is? What is the red thing; where is the redness?
Reposting my question from upthread:
I'm not quite sure I understand the problem with blueness as you see it.
Suppose nouroscience was advanced enough that it could manipulate your perception of colors in any arbitrary way just by manipulating your neurons. For example they could make you perceive blue as you previously perceived red and the other way round, induce synaesthesia and make you perceive the smell of roses, the taste of salt, the note C or other things as blue. They could change your perception of color completely, leaving your new perception of colors only as similar to your old one as that one was to your perception of smells, flavor or sounds. If all of this was true, would that be enough for you to accept that blueness is sufficiently explicable by the behaviour of neurons alone? Or would you argue that while neurons are enough to induce the sensation of blueness this sensation itself is still something beyond the mere behaviour of neurons?
