French science of the period between 1793 and 1830 is now a major focus of study. The large body of work produced since the nineteenth century, particularly in the field of institutional history, has provided the background for important attempts in the last ten or fifteen years to apply tools of sociological analysis to this field of enquiry. Particularly important have been theories of professionalization and institutionalization. It is the purpose of this paper to examine the consequences of the use (...) of such models in relation to this specific historical context. In particular, I shall suggest that such questions as the importance of institutions in the conduct of science, and the extent to which science became a profession or remained a vocation, may be better understood once the world of French science has been situated in a wider political and intellectual context. An article, however, can do no more than suggest new perspectives, and must leave to more extended treatments the work of amplification and correction. Briefly, however, this paper will argue for a view of science at this period as locked in a conflict between the ambiguous demands of the political world on the one hand, and on the other pressures on individuals and groups within the vocation of science to conform to an ideology which viewed science as completelynon-political.
