If consciousness is not epiphenomenal (and it seems you don't think it is, since you think that you need to be conscious to discuss consciousness), then either it is physical or there is an as-yet-undiscovered connection between quarks and the Realm of the Mind. Any theory which requires significant, unspecified changes to fundamental physics should receive a significant penalty.
You are getting it backwards. The physics follows the evidence, the evidence does not follow the physics, no penalty therefore for disagreeing with fundamental physics.
I don't think the connection need be between the actual quarks and the realm of the mind. The connection is probably between the unified object that is the body and it's mind, that is because all the neurons are identical and we are only aware of some of the brain's content. Free will, if it exists likely works because there is a physical law that requires that the physical reality conform to it's mental representation. This law works in reverse also, that is why you can move your arm freely but not engage in matrix-spoon bending.
Your arm moving is possible, that means that the reality will conform to the mind. You move your imaginary arm and since it corresponds to a possible state that the universe could logically assume your actual arm moves. You try and move the spoon however and the universe 'says no' because there is no logical way that such an outcome can occur and the principle hence works backwards, your mind is forced to conform to matter rather than the reverse.
Mind must conform to matter and the universe has two ways of accomplishing this. First it tries Mind-Over-Matter and then it tries Matter-Over-Mind.
1. Occam's razor does not apply to definitions and categories. "It is strictly simpler for blue to not actually exist, only objects that tend to reflect light of particular wavelengths..." Reductio ad absurdum.
2. When you say "you, unaware of it, are arguing against your own existence," you are presupposing that if KittyTac were correct about consciousness being physical, they wouldn't exist. This is combining your beliefs and KittyTac's, and then claiming that the combination is an accurate reflection of KittyTac's beliefs.
1. No, blue exists because it's existence is empirically verified by observation. Occam's Razor applies to theoretical (non-observable) explanations, not to observable things; or to put it another way, it applies to entities whose existence is indirectly proven by necessity. Consciousness (of other people) is not empirically observable, which puts it in the theoretical explanation camp and so it falls under Occam's Razor.
If I see two monkeys turning the wheel but only one monkey is needed, Occam's Razor does not establish that one of the monkeys does not exist. If I see blue, then blue exists as an entity; it is only wrong to invent something like blue when one colour would do as an explanation.
2. It is quite acceptable to assume somebody else's position in order to reveal it's internal contradictions. The irony here is that KittyTac is only disproving his own existence from MY perspective. From his perspective he is actually disproving MY existence, in both cases Occam's Razor swiftly eliminates everyone but the observer, whose consciousness stands on empiricism.
Occam's razor is, in fact, an excellent argument for physicalism, since clearly what most would call "consciousness" does exist and personality changes from brain damage etc. point toward it coming from the brain.
The possibilities are essentially that consciousness either comes from the brain or does not come from the brain and merely appears to come from the brain in every way all the way down to being profoundly affected by changes in the layout or chemical balance of the brain.
We can see why the former makes fewer assumptions.
The only existence whose existence is empirical is your own. All other consciousness are non-empirical objects, which means we don't need more of them that are necessary. If the material object that is the brain can explain everything the body does without the need of a physical consciousness 'thing' inside the brain, therefore Occam's Razor eliminates not just non-physical consciousness but conscious itself if we make consciousness physical.
Or rather it eliminates all consciousnesses *other* than the observer. Occam's Razor does not work against empirically observable things.
I definitely exist.
You can clearly see why I have a grudge on GC.
You exist because you are wrong.
