Anyone can create a whole family of blue angels, green elephants, transcendental gremlins or anything else in the rich and plastic fields of the mind, Bill. The content is not the substantial issue. The substantial issue is that these things are brought into existence and may be vanished therefrom by the owner, under the right conditions. No-one is saying you should create a science to measure blue angels or pink demons--they are just variable mock-ups from individual to individual. This is no reason to say that the existence of said owner and his relationship to those creations, and to the brain, should not be examined, especially since there is such an interesting per centage of anecdotal reports of the owner being able to let go of the brain and still perceive. THAT's the real issue.
Of course, a real hard-core jerk might argue that if it cannot be demonstrated in all human beings, then it can't be true for any of them, completely ignoring the entire spectrum of awarenesses and capabilities that is manifested across the species.
Anyway, I don't mean to be scrapping with you, pard.
