It is commonplace to hear people say such things as, ‘You shouldn’t believe that God exists—look at all the evil in the world’, or ‘You ought to believe that there is life on other planets—it’s entirely probable’, and the like. These judgements concerning what one ought (not) to believe seem to assume that there are norms governing belief, in something like the way that moral norms govern action. But what are these norms? What would account for them? How can belief be governed by such norms if, unlike action, it is not something we have control over? If belief is subject to such norms, what does this tell us about the nature of belief? The aim of this module is to explore such questions and to consider to what extent belief, like action, has an ethics.
