《孟子·告子下》6B.3：怨不是小人，亲亲之怨未尝非仁

英文参考译文

Gong Sun Chou asked about an opinion of the scholar Gao, saying, 'Gao observed, "The Xiao Pan is the ode of a little man."' Mencius asked, 'Why did he say so?' 'Because of the murmuring which it expresses,' was the reply. Mencius answered, 'How stupid was that old Gao in dealing with the ode! There is a man here, and a native of Yue bends his bow to shoot him. I will advise him not to do so, but speaking calmly and smilingly; for no other reason but that he is not related to me. But if my own brother be bending his bow to shoot the man, then I will advise him not to do so, weeping and crying the while; for no other reason than that he is related to me. The dissatisfaction expressed in the Xiao Pan is the working of relative affection, and that affection shows benevolence. Stupid indeed was old Gao's criticism on the ode.' Chou then said, 'How is it that there is no dissatisfaction expressed in the Kai Feng?' Mencius replied, 'The parent's fault referred to in the Kai Feng is small; that referred to in the Xiao Pan is great. Where the parent's fault was great, not to have murmured on account of it would have increased the want of natural affection. Where the parent's fault was small, to have murmured on account of it would have been to act like water which frets and foams about a stone that interrupts its course. To increase the want of natural affection would have been unfilial, and to fret and foam in such a manner would also have been unfilial. Confucius said, "Shun was indeed perfectly filial! And yet, when he was fifty, he was full of longing desire about his parents."'
