What is ‘Global’ About Global Justice?

Global justice has become an important part of recent political philosophy across traditions. But most of it inevitably is local thought projected onto the world stage, the globe as seen from somewhere. But how can there be a genuinely global philosophy? What do different traditions of political thought have in common, and how can we think of them as contributing to the same agenda in a shared space of ideas, rather than different traditions taking note of each other in comparative spirit? This paper explores these questions, enlisting sociological world society theory for intellectual assistance.
