Human rights and moral cosmopolitanism

What does it mean to defend moral cosmopolitanism in terms of human rights? I outline 'human rights cosmopolitanism', explain the role of equality in giving content to this conception, and defend the liberal view of human rights against the restricted view by considering - and responding to - several arguments for remaining neutral between a range of cultural and ideological perspectives on the demands of social justice and political legitimacy. I defend the liberal view that a conception of human rights should not remain neutral on controversial questions of justice and legitimacy.
