Brad DeLong has a post worrying about color perception, and in the comments thread, D-Squared correctly points out that you can’t boil problems in the phenomenology of perception down to physics or biology.
This gives me a chance to link to Dave Chalmers, friend, philosopher, blog-reader and all-round qualia expert. Dave’s book, The Conscious Mind, will tell you about consciousness and qualia of all kinds (absent, fading, dancing, inverted, others). On the specific topic of color, Alex Byrne and David Hilbert’s anthologies on the Philosophy of Color and the Science of Color might be a good place to start.
Maybe I should make a new “Philosophy” category for this blog. It would probably annoy real philosophers no end.
