"You are now bearing the punishment for the shortcomings of your world. Here, as in your world, there are benighted people who cannot tolerate thinking about things they are not accustomed to.

“As God has made the soul immortal, he has made the universe infinite, if it is true that eternity is nothing other than unlimited duration and infinity is space without limits. Suppose the universe were not infinite: God himself would be finite, because he could not be where there is nothing, and he could not increase the size of the universe without adding to his own size and come to be where he had not been before.”
