I know a desire isn't an evaluation, one evaluates the options according to, inter alia, one's desires. What do you mean by the "experience of a thought"? You seem to be talking about a Cartesian theatre.

I've demonstrated this, just a few posts ago. If I told you that I'm going to toss two coins fifty times and for each pair of tosses both coins will show the same face, and then I demonstrate it, you would not think that this was coincidence, would you?
