To know that one knows what one knows, and to know that one doesn't know what one doesn't know, there lies true wisdom.
ConfuciusThere are cases in which the blade springs, but the plant does not go on to flower. There are cases where it flowers, but no fruit is subsequently produced.
ConfuciusThe gentleman has nine cares. In seeing he is careful to see clearly; in hearing he is careful to hear distinctly; in his looks he is careful to be kind, in his manner to be respectful, in his words to be sincere, in his work to be diligent. When in doubt he is careful to ask for information; when angry he has a care for the consequences; and when he sees a chance for gain, he thinks carefully whether the pursuits of it would be right.
