Good global governance: custom, the cosmopolitan and international law

International law has both less and more to offer to the cosmopolitan project than one might think. As currently understood, international law presages a global system of obligations comprising the convergent systems of universal customary international laws and near-universal conventional instruments (treaties), both of which legal forms are characterised by natural law tendencies. From the point of view of a pluralistic cosmopolitanism, this is a dead end. Thinking beyond these formulae requires that international law be treated as a species of general law rather than state-centred law.
