The moving global Everest: A new challenge to global ideal theory as a necessary compass

I present a new challenge to the Rawlsian insistence on ideal theory as a compass orienting concrete policy choices. My challenge, focusing on global politics, consists of three claims. First, I contend that our global ideal can become more ambitious over time. Second, I argue that Rawlsian ideal theory's level of ambition might change because of concrete policy choices, responding to moral failures which can be identified and resolved without ideal theory. Third, I argue that we currently face such potentially transformative choices. I conclude that these choices are analytically prior to, rather than derivative from, global ideal theory.
