alt Hacker NewsRight. Because your eyes ... imbue the magical pixie dust ... no wait, is it your visual cortex that does it? Hmm ...
Less facetiously, I'm unclear where you believe this magic "qualia" thing to be happening and what you believe the (meta?)physical mechanism to be.
Quite a lot has been published about neural correlates of consciousness, so I'll go with whatever the evidence suggests.
There are literally hundreds of attempted explanations of phenomenal consciousness, none of which is generally accepted. For what it's worth, I think it's fundamental, i.e. not an emergent property of matter. At the very minimum, I think to be conscious of anything (other than nothing) requires the ability to sense the physical environment.
What's your position?
