ABSTRACT
This chapter focuses on what the prospect of dangerous human-induced climate change might contribute to a perennial topic in moral philosophy: the respective roles of theory and intuition. The threat of a broken world comes from human-induced climate change. Everything about climate change is controversial in public debate. In a broken world, unfamiliar cases are more common, morally salient and unfamiliar than they are in a more affluent world. In a broken world, decisions that impact on distant future people a paradigm unfamiliar case are much more significant. And those decisions are most likely to be large-scale collective decisions, not individual one-off choices. This increases the unreliability of our everyday intuitions. In a broken world, where emergencies are the norm and Rawls assumptions no longer hold, need different moral rules and cannot be confident that our intuitions will locate them for anyone.
