把这一句，留给此刻的你

The historian must have some conception of how men who are not historians behave. Otherwise he will move in a world of the dead. He can only gain that conception through personal experience, and he can only use his personal experiences when he is a genius.

历史学家必须对非历史学家的人的行为有所了解。否则，他将进入一个死的世界。他只能通过个人经验来获得这种观念，只有当他是天才的时候，他才能运用他的个人经验。

— E. M. Forster E·M·福斯特
