Wash away your old opinions to let new ideas in.

Zhu Xi was a Chinese philosopher who lived from 1130 to 1200, during the Song dynasty. A learned man, he was a historian, poet, skilled calligrapher, and astute politician — although his frank and outspoken opinions and his staunch anti-corruption ideals often saw him dismissed from court or kept a safe distance from the capital. Zhu is most associated with the development of Neo-Confucianism, influenced by the earlier teachings of the Chinese philosopher Confucius. One of Zhu’s key principles — and something he often repeated to his students — was the importance of keeping an open mind. His philosophy emphasized logic and consistency, but if the mind was closed to new ideas, it would be impossible for any student to fully realize their abilities.
