For, if I am not deceived, we are all at this moment helping to decide whether humanity shall retain all that has hitherto made humanity worth preserving, or whether we must slide down into the subhumanity imagined by Mr Aldous Huxley and George Orwell and partially realised in Hitler’s Germany. For the extermination of the Jews really would have been ‘useful’ if the racial theories had been correct; there is no foretelling what may come to seem, or even to be, ‘useful’, and ‘necessity’ was always ‘the tyrant’s plea.’10
