Abstract

Zhu Xi believes that if one attains genuine knowledge of good and evil, one will do good and avoid evil wholeheartedly. As a result, the phenomena of self-deception and akrasia pose a challenge to his moral psychology. On his deathbed, he revised his commentary on self-deception and sincerity in the book Great Learning. His final explanatory model could be understood as a moderate version of intentionalism: a self-deceiver tacitly allows room for thoughts that run counter to his ethical beliefs, even if this potentially undermines his integrity. This model highlights two major causes for self-deception: uncritical self-trust and the dubious ethical status of first-order desires. Zhu contends that thoughts cannot render themselves sincere on their own. As a remedy, he advocates an open-minded dialogue with the cultural world documented in the classics so as to avoid the myopia of the self.
