Mencius - Book 1, Part 2, Chapter 15

The duke Wan of T'ang asked Mencius, saying, 'T'ang is a small State. Though I do my utmost to serve those large kingdoms on either side of it, we cannot escape suffering from them. What course shall I take that we may do so?'

Mencius replied, 'Formerly, when king T'âi dwelt in Pin, the barbarians of the north were constantly making incursions upon it. He served them with skins and silks, and still he suffered from them. He served them with dogs and horses, and still he suffered from them. He served them with pearls and gems, and still he suffered from them.

'Seeing this, he assembled the old men, and announced to them, saying, "What the barbarians want is my territory. I have heard this, that a ruler does not injure his people with that wherewith he nourishes them. My children, why should you be troubled about having no prince? I will leave this." Accordingly, he left Pin, crossed the mountain Liang, built a town at the foot of mount Ch'î, and dwelt there. The people of Pin said, "He is a benevolent man. We must not lose him." Those who followed him looked like crowds hastening to market.

'On the other hand, some say, "The kingdom is a thing to be kept from generation to generation. One individual cannot undertake to dispose of it in his own person. Let him be prepared to die for it. Let him not quit it."

'I ask you, prince, to make your election between these two courses.'
