Abstract: Why, when asking oneself whether to believe that p, must one immediately recognize that this question is settled by, and only by, answering the question whether p is true? Truth is not an optional end for first-personal doxastic deliberation, providing an instrumental or extrinsic reason that an agent may take or leave at will. Otherwise there would be an inferential step between discovering the truth with respect to p and determining whether to believe that p, involving a bridge premise that it is good (in whichever sense of good one likes, moral, prudential, aesthetic, allthings-considered, etc.) to believe the truth with respect to p. But there is no such gap between the two questions within the first-personal deliberative perspective; the question whether to believe that p seems to collapse into the question whether p is true.
Comment: This text will be most useful in advanced Epistemology, Philosophy of Mind, Metaethics and Philosophy of Action classes. The core argument of should be manageable for students who have read a bit of epistemology/metaethics/mind, but substantial familiarity with these areas is necessary to get the paper as a whole. The paper is also valuable for its critique of Alan Gibbard’s noncognitivist account of normative judgments and J. David Velleman’s teleological account of truth’s normative governance of belief (Diversifying Syllabi).
