Mencius - Book 5, Part 1, Chapter 9B

'When he knew that the duke of Yü was not to be remonstrated with, and, leaving that State, went to Ch'in, he had reached the age of seventy. If by that time he did not know that it would be a mean thing to seek an introduction to the duke Mû of Ch'in by feeding oxen, could he be called wise? But not remonstrating where it was of no use to remonstrate, could he be said not to be wise? Knowing that the duke of Yü would be ruined, and leaving him before that event, he cannot be said not to have been wise.

'Being then advanced in Ch'in, he knew that the duke Mû was one with whom he would enjoy a field for action, and became minister to him; could he, acting thus, be said not to be wise? Having become chief minister of Ch'in, he made his prince distinguished throughout the kingdom, and worthy of being handed down to future ages; could he have done this, if he had not been a man of talents and virtue? As to selling himself in order to accomplish all the aims of his prince, even a villager who had a regard for himself would not do such a thing; and shall we say that a man of talents and virtue did it?'
