Mencius - Book 2, Part 1, Chapter 8

Mencius said, 'When any one told Tsze-lû that he had a fault, he rejoiced.

'When Yü heard good words, he bowed to the speaker.

'The great Shun had a still greater delight in what was good. He regarded virtue as the common property of himself and others, giving up his own way to follow that of others, and delighting to learn from others to practice what was good.

'From the time when he plowed and sowed, exercised the potter's art, and was a fisherman, to the time when he became emperor, he was continually learning from others.

'To take example from others to practice virtue, is to help them in the same practice. Therefore, there is no attribute of the superior man greater than his helping men to practice virtue.'
