Questions Should Have Answers

Making sense of the world often requires one to come up with new ideas, including ideas one had previously been unable to think of. How and when should this be done? I propose and defend a norm of rationality linking wondering, belief, and abilities to conceive: one must not both wonder a question and reject all answers to it that one can conceive. This norm explains judgements about an array of cases, some of which cannot be explained by appeal to more familiar doxastic norms or zetetic instrumental norms. It suggests that rationality governs not only the relations among our attitudes, but the relations among our attitudes and our abilities to have attitudes.
