The works of Emile Durkheim(1858-1917)have exerted an extraordinary influence over the development of modern social theory. This paper, the second one of my project `Giddens and Sociologists', aims to explore how Anthony Giddens, one of most famous sociologists in the contemporary world, grasp the entire structure and possibilities of Durkheim's social theory through studying his works. The main findings are as follows. First, Giddens got reflexivity which is the central concept in his structuration theory through critically studying Durukheim's theory of suicide. Reflexivity is the concept which means an essential quality of human existence as agent and a trait of social structure as condition and outcome of agency. Second, Giddens found that Durkheim's social theory is consistent and systematic by analyzing his main works. Durkheim constructed his social theory by tackling with problems concerning capitalism and nation-state in modernization. Third, Giddens succeeded in breaking through old images of Durkheim and getting clues to the development of Giddens' social theory in possibilities brought up by Durkheim.
