Human beings took our animal need for palatable food … and turned it into chocolate souffles with salted caramel cream. We took our ability to co-operate as a social species … and turned it into craft circles and bowling leagues and the Metropolitan Museum of Art. We took our capacity to make and use tools … and turned it into the Apollo moon landing. We took our uniquely precise ability to communicate through language … and turned it into King Lear.

None of these things are necessary for survival and reproduction. That is exactly what makes them so splendid. When we take our basic evolutionary wiring and transform it into something far beyond any prosaic matters of survival and reproduction … that’s when humanity is at its best. That’s when we show ourselves to be capable of creating meaning and joy, for ourselves and for one another. That’s when we’re most uniquely human.

And the same is true for sex. Human beings have a deep, hard-wired urge to replicate our DNA, instilled in us by millions of years of evolution. And we’ve turned it into an intense and delightful form of communication, intimacy, creativity, community, personal expression, transcendence, joy, pleasure, and love. Regardless of whether any DNA gets replicated in the process.

Why should we see this as sinful? What makes this any different from chocolate souffles and King Lear?
