Abstract: | Does accumulation of knowledge occur in the social sciences, and if so, under what conditions? Three research programs in Dutch sociology are evaluated with regard to theory accumulation: figurational sociology at the University of Amsterdam: structural individualistic sociology at the University of Utrecht; and data-based sociological practice at the University of Leyden. In the first two schools, a wide international orientation is accompanied by the use of a closure mechanism, i. e. a publication and citation network that is restricted to members of the same research program. The result is a high degree of theoretical unity within a context of program diversity. The article concludes with some observations on the future of Dutch sociology, followed by a list of publications in each of the three programs. |
