"'It would be possible to be much more than that. It would be possible to be every creature on every system of planets throughout the universe. My point is that for every so-called different creature, for every different person, you need a separate set of pigeon holes. But the consciousness could be the same. There could even be completely different universes. Go back to my decaying nucleus. Hook up a bomb which explodes according to whether you have decay of a nucleus or not. Make the bomb so big that it becomes a doomsday machine. Let it be capable - if exploded - of wiping out all life on the Earth. Let the whole thing go for a critical few seconds, you remember we were considering whether a nucleus would decay in a particular ten seconds? Do we all survive or don't we? 'My guess is that inevitably we appear to survive, because there is a division, the world divides into two, into two completely disparate stacks of pigeon holes. In one, a nucleus undergoes decay, explodes the bomb, and wipes us out. But the pigeon holes in that case never contain anything further about life on the Earth. So although those pigeon holes might be activated, there could never be any awareness that an explosion had taken place. In the other block, the Earth would be safe, our lives would continue - to put it in the usual phrase. Whenever the spotlight of consciousness hit those pigeon holes we should be aware of the Earth and we should decide the bomb had not exploded.'"
