If the gentleman is not serious, he will not be respected, and his learning will not be on a firm foundation. He considers loyalty and faithfulness to be fundamental, has no friends who are not like him, and when he has made mistakes, he is not afraid of correcting them.
ConfuciusTo know, is to know that you know nothing. That is the meaning of true knowledge. When you say something, say what you know. When you don't know something, say you don't know. That is knowledge.
ConfuciusThe Master said, The case is like that of someone raising a mound. If he stops working, the fact that it perhaps needed only one more basketful makes no difference; I stay where I am. Whereas even if he has not got beyond leveling the ground, but is still at work, the fact that he has only tilted one basketful of earth makes no difference. I go to help him.
