And where you say: Any way, I don't defend comp, I just show that comp makes physics derivable in arithmetic, and that if you do it in some way, (using the logic of self-reference) you can extract a general theory of qualia, with its quanta part that you can compare with nature, and so test comp. And up to now, it fits well with the facts.
What the hell are you talking about? I don't mean to be John Clark rude, but honestly, I can't see at all how qualia can possibly emerge from your theory, Cheers, and still looking for "the answer", Dan On Saturday, October 12, 2013 1:33:10 AM UTC-4, freqflyer07281972 wrote: > > Sorry to resurrect such an old thread, but I think I'd like to respond > here: > > On Saturday, November 10, 2012 4:32:16 PM UTC-5, Bruno Marchal wrote: >> >> >> On 10 Nov 2012, at 10:11, freqflyer07281972 wrote: >> >> > Hey all on the list, >> > >> > Bruno, I must say, thinking of the UDA.
