In this paper, I discuss the democratic meaning that A.Touraine mentioned the politics of Subject and the possibility of living with together in relation to questions under debate between liberalism and communitarianism. Touraine's arguments on the politics of Subject and democracy are very useful to criticize the various contemporary thinking, for example, conservative universalism and post-modernism, or liberalism and communitarianism. But, as both liberalism and communitarianism including J. Habermas and A. Giddens neglect an autonomous domain of politics that is distinguished from moral, Touraine's theory of Subject and democracy lacks concentration to the loss of alternative. His theory would may well be gone beyond him toward radical democratic politics.
