ABSTRACT: I offer a refutation of the standard argument according to which we have no doxastic obligation because we do not have the kind of voluntary control over our beliefs required for having obligations. I then propose an interpretation of the distinction between epistemic and practical reasons for belief which can be generalised to other attitudes such as intention, and seems to imply that mental acts such as judgements and decisions never count as intentional actions, and that these two sorts (...) of reasons are incommensurable.
