It is natural to see political philosophy as the domain, par excellence, of collective action and collective obligation. It is therefore surprising that the notion of collective obligation rarely assumes centre-stage within the subject. Elsewhere I have argued that we have good reasons for accepting the existence of global collective obligations - in other words, collective obligations which fall on the world’s population as a whole. Here I shall argue that in many situations, forward-looking global obligations give rise to an obligation on individuals to work towards bringing into existence and support an institutional system which will enable their obligations to be met. Call such an obligation the ‘Obligation to Promote Satisfactory Global Institutions’. I shall also examine a significant challenge to this line of argument, which I call the ‘Pluralist Challenge’.
