《旧唐书·列传·卷十九》
因此智慧的人乐于建立自己的功绩，勇敢的人喜好实行自己的志向，贪婪的人求取趋向自己的利益，愚蠢的人不计较自己的生死。 
故智者乐立其功，勇者好行其志，贪者邀趋其利，愚者不计其死。 
Therefore, wise people are happy to establish their own merits, brave people like to carry out their own ambitions, greedy people seek their own interests, and stupid people do not care about their own life or death.
