This essay critiques or engages a wide range of existing works on the ancient and well-contested issue of weakness of will, from a new perspective of comparative philosophy combined with a focus on a largely neglected Davidsonian paradox of irrationality. It aims at revealing the interplay between the descriptive and the normative in the very notion of critical interpretation, as well as a special relation between holding-true and making-true which helps to explain the non-accidentalness of the descriptive coat of the (...) Plato Principle and some of the Mencian paradigmatic tenets. By the same token, it also sheds light on some holistic picture about a certain implicit type of dynamic normativity, which seems evidently applicable to, for example, the Mencius-Xunzi 荀子 dispute on human nature, but scarcely noticed or articulated in contemporary contexts of comparative philosophy.
