The intuitive appeal of the deontological approach to epistemic justification has diminished of late, as objection has grown to the assumption of doxastic voluntarism which this approach is said to entail. (For a classic statement of the problem see Alston 1989.) With a view to defending the deontological view, Kiheyon Kim (1994) distinguishes two kinds of duties which might serve as a basis for epistemic justification: (1) the duty to form one's beliefs in a prescribed manner (2) the duty to reflect critically on the beliefs one holds. The former kind of duty would indeed require that one have direct voluntary control over one's beliefs, which is the assumption that the critics reject. Epistemic deontologists have in mind, however, according to Kim, the latter kind of duty, and the assumption of voluntarism entailed by that duty, he asserts, does not seem to be problematic. It is this last claim that I wish to call into question. That we do have the ability to critically reflect at will upon our beliefs certainly seems to be the case, in the way that our having the ability to voluntarily choose our beliefs does not. When we find ourselves troubled about a belief we often make efforts to confirm or correct it. Is it ever our duty to do so, however? Clearly, we cannot have a duty to reflect on all our beliefs. As Paul Tidman (1996) points out, so long as the duty to critically reflect on one's beliefs is formulated in utterly general terms, it is far too demanding. We do not even notice most of our ordinary, everyday beliefs, much less critically reflect upon them, yet no one would think to hold us in violation of our epistemic duty on that account. Such an unrestricted duty, moreover, would be ruled out by the principle of 'ought' implies 'can', Tidman adds, for in the course of critically reflecting on any one belief one typically forms additional beliefs. These latter beliefs would in turn call for critical reflection, so that one's duty with respect to the initial belief could never be discharged. Although Tidman argues that there is no version of epistemic duty adequate to provide for a deontological notion of epistemic justification, he considers the possibility that in some cases we may have an epistemic duty to reflect on our beliefs. Whatever other problems he sees with this duty, he seems to concur with Kim and others that it is not subject to problems of doxastic voluntarism (e.g. Steup 1988 and 1996). If the duty is to be viable, then, and it does not apply to all our beliefs, by what criteria do we pick out those beliefs to which it does apply?
