My early work in normative ethics took a broadly rule utilitarian or contractualist approach. I am now skeptical about rule-based approaches. But I see the topic as one aspect of a vast range of problems at the intersection of ethics and social epistemology that I wish to explore further.
One of the main difficulties is that different people have different beliefs, information, and evidence, along with perhaps faulty beliefs about each others beliefs, information, and evidence. Rule utilitarians seem to solve this challenging problem by pretending it isn’t one; what should the rest of us think?
