Abstract

Many would say that unlike other failures of practical rationality, which can be difficult to recognize, weakness of will wears its rational defect on its sleeve. Whenever we judge that it would be best not to do x, while intentionally doing x without relinquishing this judgment, we condemn quite explicitly the intention on which we act. This observation gives rise to the attractive idea that weak-willed agents indict themselves of irrationality as they fail to comply with their own practical judgments. Weakness of will is often treated as the paradigm of practical irrationality just because of the explicit and quasi-logical form of incoherence in the weak-willed or akratic agent’s attitudes. Underpinning this idea is the assumption that practical rationality can be characterized as a kind of executive capacity that produces congruence between judgment and action by ensuring that practical judgments are faithfully enacted. Some are happy to call this capacity the will, so that the label “weakness of will” is literally true. I will argue against both of these assumptions.
