Kohlberg's Moral-developmental theory is one of the most outstanding studies of Morality at present. But it is far from being the general theory of Morality. Because it is lacking in the perspective of the theory of Society. The purpose of this paper is an investigation of the possibility that the theory of Morality regenerates as the theory of Society, it focusing on the Reification-problem which most of sociologists regard as one of the most important social-philosophical themes in the modern society. In this paper we consider M. Horkheimer & T. W. Adorno's theory, J. Habermas's, W. Hiromatsu's, and N. Luhmann's as some examples of theories about the Post-Reificational Society. Those theories require deconstruction on Kohlberg's theory.
