 The vast majority of work carried out so far in epistemic utility theory has taken an agent’s epistemic state at time \(t\) to be modelled by her credence function at \(t\). And, in any case, the epistemic norm of Probabilism that interests us here governs agents modelled in this way. Thus, we focus on this case. In  section 7,  we will consider how the argument strategy employed here to justify Probabilism for agents with precise credences might be employed to establish other norms either for agents also represented as having precise credences or for agents represented in other ways.
