Throughout this little book, I have been suggesting that, far from being helpless in the matter of thinking morally, we have considerable powers for doing that very difficult thing. If this is so, it seems to be somewhat wasteful to entertain confused taboos and inhibitions that stop us doing it. To name a parallel, it is worthwhile remembering the fate of the Margrave of Brandenburg. He seems not to have bothered to look at his post, and therefore he never opened a particular parcel of music that had been sent to him as a present by some tiresome choirmaster. It was found unopened at this death.
