《孔子家语·困誓》
我听说，如果对牲畜有剖腹取胎的残忍行为，那么麒麟就不会来到这个国家的郊外；如果有竭泽而渔的行为，蛟龙就不会在这个国家的水中居住；捅破了鸟巢打破了鸟卵，凤凰就不会在这个国家的上空飞翔。为什么呢？
丘闻之，刳胎杀夭，则麒麟不至其郊；竭泽而渔，则蛟龙不处其渊；覆巢破卵，则凤凰不翔其邑。
I heard that if there are cruel acts of cutting open animals and taking their fetuses, then the qilin will not come to the outskirts of this country; if there are acts of exhausting the lake in order to catch fish, then the Chinese dragon will not reside in the waters of this country; if nests are pierced and eggs are broken, then the phoenix will not fly over the skies of this country. Why is that?
