A traditional concern for determinists is that the epistemic conditions an agent must satisfy to deliberate about which of a number of distinct actions to perform threaten to conflict with a belief in determinism and its evident consequences. I develop an account of the sort that specifies two epistemic requirements, an epistemic openness condition and a belief in the efficacy of deliberation, whose upshot is that someone who believes in determinism and its evident consequences can deliberate without inconsistent beliefs. I (...) argue that conditions of both types are indispensable, and that they can be formulated so as to withstand the relevant objections. (shrink)
