Abstract:The ethical relativism shows that moral has its own particularity and relativity, but it does not deny the universality and absoluteness of moral. Such relativism is not good to the moral education to minors and might bring destruction to the traditional excellent culture. This might lead to the value nihility of moral. The fact that the moral situation is object but its subject is subjective provides the possibility for the moral reconstruction. Moral eventually has its own certainty which is not the same as absoluteness. Human should keep the balance between the moral relativism and absolutism.
