Rational requirements and ‘rational’ akrasia

Abstract

Can akrasia be rational? Can it be rational to resist the motivational force of your own practical judgment? While I do not believe that akrasia can be rational, I think there is something revealingly right in recent arguments for the proposition. I aim to defend that insight in a way that does not entail that akrasia can be rational but more fundamentally addresses the normative structure of rational requirements. The fundamental issue lies in the relationship between two conceptions of rationality. Previous treatments of ‘rational’ akrasia have tended to regard rationality as a responsiveness to reasons. Previous treatments of rational requirements have tended to regard rationality as an attitudinal coherence. I’ll reformulate the question of rational akrasia within a framework that construes rationality as coherence. And I’ll reformulate the question of rational coherence to admit the possibility of reasoning as the apparently rational akratic does—from failure to follow through on a judgment to abandonment of that judgment. I’ll argue that rational requirements codify an agential coherence that you negotiate through a dynamic of self-trust and self-mistrust. It is not reasoning to abandon your judgment through forgetfulness, confusion or perverse self-rebellion. But it can be reasoning to abandon your judgment through reasonable self-mistrust. The difference lies in how self-mistrust can manifest a sensitivity to the norm of rational coherence that gives normative force to rational requirements. The core insight of those who defend the possibility of ‘rational’ akrasia lies in their emphasis on the rational force of self-mistrust.
