Every historian loves the past or should do. If not, he has mistaken his vocation; but it is a short step from loving the past to regretting that it has ever changed. Conservatism is our greatest trade-risk; and we run psychoanalysts close in the belief that the only "normal" people are those who cause no trouble either to themselves or anybody else.
Conformity may give you a quiet life; it may even bring you to a University Chair. But all change in history, all advance, comes from the nonconformists. If there had been no trouble-makers, no Dissenters, we should still be living in caves.
If there had been a strong democratic sentiment in Germany, Hitler would never have come to power . [Germans] deserved what they got when they went round crying for a hero.
In my opinion we learn nothing from history except the infinite variety of men's behaviour. We study it, as we listen to music or read poetry, for pleasure, not for instruction.
