Charles Eisenmann proposes the same type of division between legal and political science. The attitude of jurists toward social sciences is heterogeneous, ambivalent and even, for some, hostile. The classical legal method is said to be blind, upstream, to the real conditions – the real sources – of the production of legal norms and, downstream, to their concrete effects. Many jurists have turned to the field of different social sciences such as philosophy, sociology, political science, history, economics, psychology, geography and so on in order to revitalize the study of law. The dialogue between the legal sciences and the other social sciences faces several difficulties, starting with the question of the identity of a studied object. The social sciences are only mobilized to complete or correct the modes of analysis of law that jurists usually employ, in a subsidiary, auxiliary or annexed capacity.
