"Take the Catholic idea — and I speak as a convinced atheist — the Catholic idea of original sin, fascinating idea, beautiful idea, starts from the notion that the human animal is crooked. We are slightly wrong and imperfectable. The only perfectable creature out there is divine. That is the source of perfection. The human animal is a mixture of the divine and the not divine. And so, in other words, perfectability is not in our nature and we shouldn’t aim for it.
Now this could seem a bit dark and pessimistic, but imagine trying to have a relationship with someone who thinks that perfectability is within their grasp, someone young, good-looking…very optimistic, who thinks I’m going to get together with another similarly perfect being and we can have a fantastic, terrific time. I mean, watch out for the divorce lawyers and the alarm bells. That’s not going to work. Whereas if two people come together and go, look, I’m a little nuts and you’re probably a little nuts too ‘cause, you know, you’re human, but we’re going to try and make a go of it, you know, against the deep backdrop of human fallibility — I’d give that relationship much more of a vote, because it’s going to be based on reality.”
