It is a popular opinion among scholars that Max Weber's ”Gesinnungsethik” and ”Verantwortungsethik” are contradictory to each other, and Kant's ethics is often regarded as a type of the former. Therefore, it is viewed as self-contradictory, to interpret Confucianism in terms of Kant's ”moral autonomy” and ”Gesinnungsethik,” together with Weber's ”Verantwortungsethik”. In this paper, by an analysis of Kant's and Weber's texts, I demonstrate that Weber's criticism of ”Gesinnungsethik” is not suitable for Kant's ”Gesinnungsethik”. Not only Kant's ”Gesinnungsethik” and Weber's ”Verantwortungsethik” are logically compatible, the former even implies the latter. Finally, I show that the Confucianism, as Confucius and Mencius advocate, has two dimensions which correspond to Kant's ”Gesinnungsethik” and Weber's ”Verantwortungsethik” respectively.
