莎士比亚《哈姆雷特》第一幕里波洛涅斯叮咛他即将出行的儿子的那段“绝妙好词”——
    
     还有几句教训，希望你铭刻在记忆之中：不要想到什么就说什么，凡事必须三思而行。对人要和气，但不要过分狎昵。相知有素的朋友，应该用钢圈箍在你的灵魂上，可是不要对每一个泛泛的新知滥施你的交情。留心避免和人家争吵；可是万一争端已起，就应该让对方知道你不是可以轻侮的。倾听每一个人的意见，可是只对极少数人发表你的意见；接受每一个人的批评，可是保留你的判断。尽你的财力购制贵重的衣服，可是不要炫新立异，必须富丽而不浮艳，因为服装往往可以表现人格；法国的名流要人，就是在这一点上显得最高尚，与众不同。不要向人告贷，也不要借钱给别人；因为债款放了出去，往往不但丢了本钱，而且还失去了朋友；向人告贷的结果，容易养成因循懒惰的习惯。尤其要紧的，你必须对你自己忠实；正像有了白昼才有黑夜一样，对自己忠实，才不会对别人欺诈。

Yet here, Laertes! aboard, aboard, for shame!
The wind sits in the shoulder of your sail,
And you are stay'd for. There; my blessing with thee!
And these few precepts in thy memory
See thou character. Give thy thoughts no tongue,
Nor any unproportioned thought his act.
Be thou familiar, but by no means vulgar.
Those friends thou hast, and their adoption tried,
Grapple them to thy soul with hoops of steel;
But do not dull thy palm with entertainment
Of each new-hatch'd, unfledged comrade. Beware
Of entrance to a quarrel, but being in,
Bear't that the opposed may beware of thee.
Give every man thy ear, but few thy voice;
Take each man's censure, but reserve thy judgment.
Costly thy habit as thy purse can buy,
But not express'd in fancy; rich, not gaudy;
For the apparel oft proclaims the man,
And they in France of the best rank and station
Are of a most select and generous chief in that.
Neither a borrower nor a lender be;
For loan oft loses both itself and friend,
And borrowing dulls the edge of husbandry.
This above all: to thine ownself be true,
And it must follow, as the night the day,
Thou canst not then be false to any man.
Farewell: my blessing season this in thee!
