7853 Confucius           Discovered 1973 Jan. 29 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named after Confucius (551-471 B.C.), the famous Chinese philosopher. Nothing written by Confucius has survived, but his pupils compiled a collection of his sayings and anecdotes in the Master Cung. Confucius was convinced that the self-discipline and virtue shown by society's leaders would influence everyone. During the Han dynasty, Confucius was venerated as a god, and in the Sung dynasty his rules of living filtered into politics and education.
