That's the whole point of what I'm getting at, that that's a heck of a bullet to bite (viz., rejecting the law of the excluded middle).
I'm pretty sure that is not the physicist's position. The cat is either a live or dead, the question is not is there a superposition of the quantum particle involevd - There IS. Period. The question is, at what point does that superposition resolve itself? What is the observer and at what point does it observe.
