Jin Xin I · 孟子 7A.31
Passage 31
公孫丑曰:「伊尹曰:『予不狎于不順。』放太甲于桐,民大悅;太甲賢,又反之,民大悅。賢者之為人臣也,其君不賢,則固可放與?」孟子曰:「有伊尹之志,則可;無伊尹之志,則篡也。」
Gong Sun Chou said, 'Yi Yin said, "I cannot be near and see him so disobedient to reason," and therewith he banished Tai Jia to Tong. The people were much pleased. When Tai Jia became virtuous, he brought him back, and the people were again much pleased. When worthies are ministers, may they indeed banish their sovereigns in this way when they are not virtuous?' Mencius replied, 'If they have the same purpose as Yi Yin, they may. If they have not the same purpose, it would be usurpation.'
