Peter Kreeft asks what sex is in Heaven, and says that first we must know what it is on earth.
But don’t we know? Haven’t we been thinking about almost nothing else for years and years? What else dominates our fantasies, waking and sleeping, twenty-four nose-to-the-grindstone hours a day? What else fills our TV shows, novels, plays, gossip columns, self-help books, and psychologies but sex?No, we do not think too much about sex; we think hardly at all about sex. Dreaming, fantasizing, feeling, experimenting – yes. But honest, look-it-in-the-face thinking? – hardly ever. There is no subject in the world about which there is more heat and less light.
He then gives four principles on which he bases a conclusion. It’s a good read.
