Mencius said, 'Supposing that the kingdom of Ch'î were offered, contrary to righteousness, to Ch'an Chung, he would not receive it, and all people believe in him, as a man of the highest worth. But this is only the righteousness which declines a dish of rice or a plate of soup. A man can have no greater crimes than to disown his parents and relatives, and the relations of sovereign and minister, superiors and inferiors. How can it be allowed to give a man credit for the great excellences because he possesses a small one?'~ James Legge translation via nothingistic.org ~
