The story is told that when leibnitz propounded the maxim of variety , the cavaliers and ladies of the court , as they walked round the garden , made efforts to discover two leaves indistinguishable from each other , in order to confute the law stated by the philosopher .
Read not to contradict , and confute ; nor to believe and take for granted ; nor to find talk and discourse ; but to weight and consider .
读书不可存心诘难读者,也不可尽信书上所言,亦不可只为寻章摘句,而应推敲细思。
Francis bacon : read not to contradict and confute , not to believe and take for granted , nor to find talk and discourse , let to weigh and consider .
