"Oh, I know a dozen or so well, a few thousands somewhat less."
"Would it be possible to know a hundred thousand people, a half million?"
"A mentalist might know that many to recognize; I don't know the limit. But darkened man has a limit set on everything."
"Could a somehow emancipated man know more?"
"The only emancipated man is the corporally dead man. And the dead man, if he attains the beatific vision, knows all other persons who have ever been since time began."
"All the billions?"
"All."
"With the same brain?"
"No. But with the same mind."
"Then wouldn't even a believer have to admit that the mind which we have now is only a token mind? Would not any connection it would have with a completely comprehensive mind be very tenuous? Would we really be the same person if so changed? It is like saying a bucket would hold the ocean if it were fulfilled, which only means filled full. How could it be the same mind?"
