Unlike many philosophers of his time who focus on the union between Heaven and man, XunZi pays more attention on their differences. In his ideology, the Heaven does not take on a moral character by interacting with man; and man is not considered as essentially good simply because he is in harmony with nature. Man is morally blank in his original stage. Being independent of Heaven, it is necessary to place emphasis on human actions. This stress diverts him away from Confucius and MengZi's way of understanding.
