“In the part of this universe that we know there is great injustice, and often the good suffer, and often the wicked prosper, and one hardly knows which of those is the more annoying; but if you are going to have justice in the universe as a whole you have to suppose a future life to redress the balance of life here on earth. So they say that there must be a God, and there must be heaven and hell in order that in the long run there may be justice.”
