Of course I can write
main() {
printf("Nothing is real.\n");
}
But is this convincing? I could also say "nothing is real", yet I continue to
eat, breathe, sleep, go to work, budget my money, not drive recklessly, not
jump off a cliff, and do all the other things that would make no difference to
my survival if I were dreaming. So would you believe that I don't believe in
reality just because I say so?
So my question is what aspect of behavior could be used as a test for belief
in reality? The test ought to be applicable to humans, animals, robots, and
computer programs. I believe the most general test is response to
reinforcement learning. Suppose that you could not experience pain or
pleasure or any emotion, so that you would impassively accept any kind of
disease, disability, torture, or death, as unconcerned as if you were reading
a work of fiction. Would you believe in reality then?
