If one fails to practice “Shendu”(ethical self-cultivation), one remains merely a “quantitative” individual rather than a “qualitative” individual. An “quantitative” individual, through idle talk, curiosity, and ambiguity, evacuates personal substance, thereby failing to overcome the banality of evil. Although “Shendu” is often regarded as a unique concept in Chinese intellectual histroy, there still exists a latent idea of it in the history of Western thought. It is through this concept that the banality of evil can be overcome and moral education can be accomplished. Socrates’ idea that “I would rather be in discord with the whole world than be in discord with myself ”, Kant’s thought that “Immaturity is the inability to use one’s understanding without guidance from another”, Maritain’s notion that “Subjectivity as subjectivity cannot be conceptualized; it is an unfathomable abyss of unknowability”, and Arendt’s concept of “being in silent dialogue with oneself ” all resonate with the traditional Chinese concept of “Shendu”. In their view, only through “Shendu” can a “qualitative” individual stand up and overcome the banality of evil inherent in the “quantitative” individual. True moral education, then, is precisely that which elevates the “qualitative” individual—this constitutes its ultimate fulfillment.
