Experience never misleads; what you are missed by is only your judgement, and this misleads you by anticipating results from experience of a kind that is not produced by your experements. (Leonardo Da Vinci, Italian painter)
经验永远不会对你做错误的引导；把你引导错的只是你自己的判断，而你的判断之所以对你发生误导的作用，乃是由于它根据那种并非借着实验而产生的经验来预料的结果。(意大利画家 达芬奇)
