Mencius - Book 2, Part 1, Chapter 2H

'Tsze-kung said, "By viewing the ceremonial ordinances of a prince, we know the character of his government. By hearing his music, we know the character of his virtue. After the lapse of a hundred ages I can arrange, according to their merits, the kings of a hundred ages; not one of them can escape me. From the birth of mankind till now, there has never been another like our Master."

'Yû Zo said, "Is it only among men that it is so? There is the Ch'î-lin among quadrupeds, the Fang-hwang among birds, the T'âi mountain among mounds and ant-hills, and rivers and seas among rain-pools. Though different in degree, they are the same in kind. So the sages among mankind are also the same in kind. But they stand out from their fellows, and rise above the level, and from the birth of mankind till now, there never has been one so complete as Confucius."'
