ABSTRACT
This chapter reconsiders the problem of mononaturalism, not as an obstacle to modeling scientific practices while remaining committed to realism, but as a political and legal peril. The first part provides a modicum of historical perspective on the political tradition into which actor-network theory inscribes itself by way of both compositionism and cosmopolitics, by constructing an adumbrated genealogy, organized around the theme of cosmopolitanism. The second and third sections return to the core theme of matters of concern through the prism of law in its relation to the politics of the cosmos. The second asks about how law contributes to the composition of a common world and the integral ecology of practices, while the third begins again by asking how law works against the current of that project. The chapter argues that there is a cosmopolitical practice of law that furthers it: comparative law.
