In The Law of Peoples Rawls claims that liberal well-ordered societies (LWOSs) should regard certain non-liberal societies, decent hierarchical societies (DHSs), as equal members of a just international order, a ‘Society of Peoples.’ Rawls maintains, however, that while the ‘basic structures’ (the main political and economic institutions) of LWOSs are fair systems of social cooperation, the basic structures of DHSs are only ‘decent’ systems of social cooperation. I explain why the basic structures of DHSs cannot be fair systems of social (...) cooperation. In doing so, I refute a recent defense of DHSs advanced by Samuel Freeman. I then argue that because the basic structures of DHSs cannot be fair systems of social cooperation, Rawls is not justified in holding that LWOSs should refrain always from offering economic incentives to DHSs in order to encourage them to liberalize their political institutions. The ultimate aim of the foreign policies of LWOSs should be a world in which liberal democratic rights are respected by all societies. (shrink)
