 Alternatively, one might acknowledge the force of the Preface intuitions while at the same time trying to hold on to a strict, ought-based principle. But how? According to all such principles, I, the author of a non-trivial non-fiction book (let us assume), ought to believe (or at least not disbelieve) the conjunction of the propositions in my book, given that I firmly endorse each conjunct individually. MacFarlane’s response is that we must simply reconcile ourselves to the irreconcilable: the existence of an ineliminable normative conflict. Our strict logical obligations clash with other epistemic obligations, namely, the obligation to believe that some of my beliefs must be mistaken. Our agent becomes a tragic heroine. Through no fault of her own, she finds herself in a situation in which, no matter what she does, she will fall short of what, epistemically speaking, she ought to do.
