《淮南子·主术训》
而那些天质愚笨者，是不能授予重要权力的。鱼得到水才能游得快乐；如果池塘决口水干涸，脱离了水的鱼就可能被蝼蛄蚂蚁所吞食。
鱼得水而游焉则乐，唐决水涸，则为蝼蚁所食。
And those who are naturally foolish should not be given important responsibilities. Fish can only swim happily when they have water; if the pond dries up and the fish are left stranded, they may be eaten by ants and crickets.
