I really tried to address that issue before you raised it, like when I said "I should be careful to add that our changing perception hasn't changed the universe itself, but it has potentially altered the known world as we perceive it." If our perception of the phenomenal world were to change, that by itself wouldn't change the noumenal world. A change in the noumenal world doesn't matter, though, because we wouldn't be able to detect it anyway. The only thing we have perception of, and access to, is the world of our perceptions, that is, the phenomenal world.

If you're calling a change in perception "willful delusion," then you have to call all perception "willful delusion." I actually don't have a problem with that if you do (certainly the Buddhists would agree with you), but I think that such an argument works in my favor, not yours.

I'm really not trying to dissuade you from writing essays like your diatribe against pseudoscience, just arguing that in this particular case there's more than meets the scientific eye. If you left your complaint with palmistry and magic crystals I wouldn't have anything to add. The "power" of positive thinking, though, does have some potentially valid philosophical basis, and that's all I'm pointing out.
