Mencius - Book 4, Part 2, Chapter 19

Mencius said, 'That whereby man differs from the lower animals is but small. The mass of people cast it away, while superior men preserve it.

'Shun clearly understood the multitude of things, and closely observed the relations of humanity. He walked along the path of benevolence and righteousness; he did not need to pursue benevolence and righteousness.'
