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.
All wisdom is rooted in learning to call things by the right name. When things are properly identified, they fall into natural categories and understanding becomes orderly.
If I am walking with two other men, each of them will serve as my teacher. I will pick out the good points of the one and imitate them, and the bad points of the other and correct them in myself.
