《古代寓言·长生不老的仙方》（中英对照）

客有教燕王为不死之道者，王使人学之，所使学者未及学，而客死，王大怒诛之。王不知客之欺已，而诛学者之晚也，夫信不然之物，而诛无罪之臣，不察之患也，且人所急无如其身，不能自使其无死，安能使王长生哉！

——《韩非子》

A Recipe for Immortality

A stranger informed the Prince of Yan that he could make him immortal, and the prince bade one of his subjects learn this art; but before the man could do so the stranger died. Then the prince, in great anger, executed his subject.

He failed to see that the stranger was cheating him, but taken in by his lies had an innocent citizen killed. This shows what a fool he was! For a man values nothing more than his own life, yet his fellow could not even keep himself alive, so what could he do for the prince?
