Rationality is the type of normativity that by its nature is sensitive to a person’s mental states. But now suppose a person doubts or disbelieves a rule obedience to which is required by the putatively correct account of rationality. Should this change what is rational for this person? Sepielli proposes a framework for thinking about this question, and argues for an answer within that framework. He discusses the problem within the context of the debate about what to do under moral uncertainty, and then suggest that the framework he proposes may be helpful in addressing some vexing problems in epistemology.
