How is a sociology of sociological knowledge possible?

By deconstructing Merton's distinction between the history and systematics of sociological thought, this paper aims first at uncoupling the process of legitimation of sociology as a scientific discipline from classical narratives commonly arranged around the ''founding fathers''. Second a constructivist approach to the history of sociology is deployed by dealing with issues of reflexivity. Drawing on the concept of autopoiesis, internal links are highlighted between the chance of persistence of a scientific domain and the conditions of its possibility. In line with Steve Woolgar; a reflexive Sociology of sociological Knowledge (SsK) is said to be possible try deconstructing the standard view of science, and its implementation within social sciences. This requires an integration off (a) the post-structuralist concept of ''discipline'' as put forward by Michel Foucault; (b) postmodern theories prompting an understanding of cognitive differentiation of scientific discourser as a kind of ''self-similarity'' within a given episteme; and (c) Niklas Luhmann's systems theory focusing on the functional differentiation of science.
