The paper contrasts Kant's conception of original common possession of the earth with Hugo Grotius's superficially similar notion. The aim is not only to elucidate how much Kant departs from his natural law predecessors—given that Grotius's needs-based framework very much lines in with contemporary theorists’ tendency to reduce issues of global concern to questions of how to divide the world up, it also seeks to advocate Kant's global thinking as an alternative for current debates. Crucially, it is Kant's radical shift (...) in perspective—from an Archimedean ’view from nowhere‘, to a first-personal standpoint through which agents reflexively recognise their systematic interdependence in a world of limited space—that provides him with the more thorough and ultimately convincing global standpoint. This standpoint does not come with ready-made solutions to shared global problems, but provides a promising perspective from which to theorise them. (shrink)
