No man, for any considerable period, can wear one face to himself and another to the multitude, without finally getting bewildered as to which may be the true.

世界是一本书，不旅行的人只读了一页。

这是最幸运的年代，也是最倒霉的年代，这是智慧的年代，也是愚昧的年代；这个时期信仰与怀疑共存，这个时期光明与黑暗共存；这是希望之春，也是失望之冬；人们面前琳琅满目，但又一无所有；我们正直达天堂，我们正直通地狱。

A method of solution is perfect if we can foresee from the start, and even prove, that following that method we shall attain our aim.

世界是一个谜题；碎片散落一地，没有人有盒子上的图片。
