Listen widely to remove your doubts and be careful when speaking about the rest and your mistakes will be few.
ConfuciusOn matters beyond his ken a gentleman speaks with caution. If names are not right, words are misused. When words are misused, affairs go wrong. When affairs go wrong, courtesy and music droop, law and justice fail. And when law and justice fail them, a people can move neither hand nor foot. So a gentleman must be ready to put names in speech, to put words into deeds. A gentleman is nowise careless of words.
ConfuciusWhen the Superior Man eats he does not try to stuff himself; at rest he does not seek perfect comfort; he is diligent in his work and careful in speech. He avails himself to people of the Tao and thereby corrects himself. This is the kind of person of whom you can say, "he loves learning."
ConfuciusWhat is God-given is called nature; to follow nature is called Tao (the Way); to cultivate the way is called culture. Before joy, anger, sadness and happiness are expressed, they are called the inner self; when they are expressed to the proper degree, they are called harmony. The inner self is the correct foundation of the world, and the harmony is the illustrious Way. When a man has achieved the inner self and harmony, the heaven and earth are orderly and the myriad of things are nourished and grow thereby.
