Abstract: Relative to the personal good,the good of community is often placed in a more important position by the communitarianism,and the source of this understanding is the overemphasis on community,so the good of community need to get rid of charm. Nevertheless,this does not mean that the liberal principle of value neutrality can be established. On the contrary,there is a contradiction and discord between the principle and the proposition "right is prior to good" that is put forward by the liberalists,which will cause a breach of the social reality of value diversification. In this sense,the high degree of vigilance must be kept on the tendency to absolute rights. After all,the situation in real life is not always able to be expressed in the form of "rights dialogue",and the development of right standard theory to the extreme can create rigidity and division,thus leading to more serious social problems.
