Mencius - Book 5, Part 2, Chapter 1C

Mencius said,'Po-î among the sages was the pure one; Î Yin was the one most inclined to take office; Hûi of Liû-hsiâ was the accommodating one; and Confucius was the timeous one.

'In Confucius we have what is called a complete concert. A complete concert is when the large bell proclaims the commencement of the music, and the ringing stone proclaims its close. The metal sound commences the blended harmony of all the instruments, and the winding up with the stone terminates that blended harmony. The commencing that harmony is the work of wisdom. The terminating it is the work of sageness.

'As a comparison for wisdom, we may liken it to skill, and as a comparison for sageness, we may liken it to strength; as in the case of shooting at a mark a hundred paces distant. That you reach it is owing to your strength, but that you hit the mark is not owing to your strength.'
