译文：有一种忠心被人视为愚行，就是“愚忠”，也有一种孝行被人视为愚行，那是“愚孝”，由此可知，“忠”，“孝”两个字，太过聪明的人是做不来的。同样地，仁和义的行为中，也有虚伪的“假仁”和“假义”，由此可以知道，在一般人所说的仁义之士中，不见得没有奸险狡诈的人。

"Facts are not truth, though they are part of it."

In mathematics, the art of proposing a question must be held of higher value than solving it.

真理不会在愤怒中被说出。如果有朝一日真理被说出，那一定是在爱中。
