Western tradition of ethics was based on religious faith,but since modern society,the traditional religion has been critiqued by modernity thoroughly.Faith has been shrinking under the pressure of the expansion of rational knowledge,the religion basis of moral is dissolved and replaced by a rational.However,the reason can not fill the vacuum belief in modern society,resulting in a modern society not only facing serious "presence" crisis but facing an unprecedented crisis of the spirit.Thus,with the vision on modernity transcendence and radical postmodernism,constructive postmodernism reestablished beliefs and values?? from the overall relationship between man and man,and between man and the world,showing a tendency to rebound religion,and to some extent,indicating the return of the religious faith basis of moral.
