Before the Second World War I believed in the perfectibility of socialman; that a correct structure of society would produce goodwill; and that therefore you could remove all social ills by a reorganisation of society. … after the war I did not because I was unable to. I had discovered what one man could do to another. ... I am thinking of the vileness beyond all words that went on, year after year, in the totalitarian states. It is bad enough to say that so many Jews were exterminated in this way and that, so many people liquidated — lovely, elegant word — but there were things done during that period from which I still have to avert my mind less I should be physically sick. They were not done by the headhunters of New Guinea or by some primitive tribe in the Amazon. They were done, skillfully, coldly, by educated men, doctors, lawyers, by men with a tradition of civilization behind them, to beings of their own kind.
