T'âo Ying asked, saying, 'Shun being sovereign, and Kâo-yâo chief minister of justice, if Kû-sâu had murdered a man, what would have been done in the case?'
Mencius said, 'Kâo-yâo would simply have apprehended him.'
'But would not Shun have forbidden such a thing?'
'Indeed, how could Shun have forbidden it? Kâo-yâo had received the law from a proper source.'
'In that case what would Shun have done?'
'Shun would have regarded abandoning the kingdom as throwing away a worn-out sandal. He would privately have taken his father on his back, and retired into concealment, living some where along the sea-coast. There he would have been all his life, cheerful and happy, forgetting the kingdom.'~ James Legge translation via nothingistic.org ~
