Friendship with the upright, with the truthful and with the well informed is beneficial. Friendship with those who flatter, with those who are meek and who compromise with principles, and with those who talk cleverly is harmful.
What 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.
Among us, in our part of the country, those who are upright are different from this. The father conceals the misconduct of the son, and the son conceals the misconduct of the father. Uprightness is to be found in this.
