In this paper I discuss a number of different relationships between two kinds of obligation: those which have individuals as their subject, and those which have groups of individuals as their subject. I use the name collective obligations to refer to obligations of the second sort. I argue that there are collective obligations, in this sense; that such obligations can give rise to and explain obligations which fall on individuals; that because of these facts collective obligations are not simply reducible (...) to individual obligations; and that collective obligations supervene on individual obligations, without being reducible to them. The sort of supervenience I have in mind here is what is sometimes called ‘global supervenience’. In other words, there cannot be two worlds which differ in respect of the collective obligations which exist in them without also differing in respect of the individual obligations which exist in them.

According to Kant, it is impermissible to treat humanity as a mere means. If we accept Kant's equation of humanity with rational agency, and are literalists about ascriptions of agency to collectives it appears to follow that we may not treat collectives as mere means. On most standard accounts of what it is to treat something as a means this conclusion seems highly implausible. I conclude that we are faced with a range of options. One would be to rethink the (...) equation of humanity with rationality. Another would be to abandon the prohibition on treating as a means. The last would be to abandon literalist construals of attribution of agency to collectives. (shrink)
