Philip Pettit

In common-sense morality, certain special obligations loom large. These are duties which are laid upon agents, be they individuals or groups, in virtue of their distinctive identities, relationships or histories: because of who they are, how they are linked to others or what they have done in the past. The particularistic basis of these obligations means that no one but the agent in question is engaged by such a duty. It is that agent's alone.These special obligations include duties towards oneself, towards one's dependants and towards those to whom one has made certain commitments. In each case they prescribe partisan treatment. The beneficiary is to enjoy a benefit which may not be especially important in the global scheme of things, and which may even be obtained at the cost of others’ being deprived of benefits that are equally or more important in some cosmic sense.
