一九三七年八月

The uniformity of the hybrids in the first generation, the dissimilarity in the second, are facts which cannot escape the attention of an accurate observer.

領導力在于以清晰的愿景做出艱難決策。

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.

"The only true wisdom is in knowing you know nothing."

譯文：江頭上的風波還不算最險惡的，人間的道路比這還要難行得多!

出自北齊·顏之推《顏氏家訓·勉學》。不得，不能、不可。雌黃，礦物名，可作顏料，古代用以涂改文字，后引申為信口更改、隨便亂說。沒有讀夠一定數量的書，對前人的見解沒有徹底了解，是不能隨便亂下結論、亂發議論的。書要多讀、話要謹慎；應當謙虛向學，不可妄自尊大。
