Louis Pojman on Ethics and the Afterlife"A Critique of Moral Relativism", in Ethical Theory (Wadsworth, 1998), 49.
Imagine that you have been miraculously transported to the dark kingdom of hell, and there you get a glimpse of the sufferings of the damned. What is their punishment? Well, they have eternal back itches, which ebb and flow constantly. But they cannot scratch their backs, for their arms are paralyzed in a frontal position, so they writhe with itchiness throughout eternity. But just as you are beginning to feel the itch in you own back, you are suddenly transported to heaven. What do you see in the kingdom of the blessed? Well, you see people with eternal back itches, who cannot scratch their own backs. But they are all smiling instead of writhing. Why? Because everyone has his or her arms stretched out to scratch someone else’s back, and, so arranged in one big circle, a hell is turned into a heaven of ecstasy. In our story people in heaven, but not in hell, cooperate for the amelioration of suffering and the production of pleasure. These are very primitive goods, not sufficient for a full-blown morality, but they give us a hint as to the objectivity of morality. Moral goodness has something to do with the ameliorating of suffering, the resolution of conflict and the promotion of human flourishing.
