Wei Dai, you should read cautiously SMULLYAN'S "An Epistemological Nightmare". You will understand at once that, with comp, there is no hope to use any "scientific theory" to build a "decision theory". With comp, the best decision theory you will ever find is YOU ! Whatever YOU are. Nothing less, nothing more. BTW I like Stanislaw Lem a lot too. I want also say that Mind's I is my favorite work by both Hofstadter and Dennett. Although when it has been published I got depressed thinking my thesis has been worked out by others. It takes me time to realise it was not the case. Holliday exercice : there is a proposition P such that Hofstadter believes P in his remark on quantum mechanics, and believes NOT P in his "conversation" with Einstein's brain, (both in Mind's I), which is P ? Bruno.
