Theory of Evil Human Nature
He said that man-made methods should be used to change the evil results. The nature of Mencius ' theory of good nature takes the essential meaning, that is, the difference between human beings and animals, the inner morality of human beings, that is, the four virtues, human beings have the nature of being good, and the internal source of value. And Mencius should not object to the natural nature of man, because this is clearly observed in experience. The definition of evil nature theory is that if people follow the natural nature, it will cause evil results; while goodness is acquired through learning and hard work. The implication is that although the nature of nature is not evil, it is the source of evil effects. It can be seen from the argument given by Xunzi at the beginning of Xing Evil, although Xunzi failed to explain the root of value, but this definition is tenable, because we can correct the problem of the root of value in his theory, such as the root of value is external to man, such as religion.
