Subjectivists about practical normativity hold that an agent’s favoring and disfavoring attitudes give rise to practical reasons. On this view, an agent’s normative reason to choose vanilla over chocolate ice cream ultimately turns on facts about what appeals to her rather than facts about what her options are like attitude-independently. Objectivists—who ground reasons in the attitude-independent features of the things we aim at—owe us an explanation of why it is rational to choose what we favor, if not because favoring is (...) a source of reasons. My aim in this paper is to supply such a story. The proposal is roughly that when an agent cannot base her choices on her judgments about what she has most reason to do, structural rationality extends to her a license to choose something just because she favors it, without imbuing favoring with the authority of a normative reason.
