釋義：看到已經(jīng)發(fā)生的事情要謹慎對待將要發(fā)生的事情，厭惡某種行為軌跡的人必須避開它。害怕危險的人才能平安，害怕滅亡的人才能生存。這是對謹慎行事、防患未然的智慧的強調(diào)。

I'm mentioning all this -- I'm mentioning all this because I think this is not merely a personal problem; you may think I'm wrong in this, but I think we live in an age when our lives are regularly punctuated by career crises, by moments when what we thought we knew -- about our lives, about our careers -- comes into contact with a threatening sort of reality.

在探索現(xiàn)實的基本性質(zhì)的追求中，我們必須準備好質(zhì)疑我們認為我們所知道的一切。

All is number.
