The present study examines the four core concepts that underpin the various theories of cultivation of East Asian Confucian philosophy: self, cultivation, transformation, and nurture. The discussion is divided into six sections. The first section, the introduction, explains the significance of the issue in question. The second section examines the substantial notion of “self” as expounded in the Confucian intellectual tradition and the corresponding concept of selfhood or personhood. Confucianism stresses that personal selfhood is based on the freedom of subjectivity, (...) and society’s values and norms originate in this freedom of subjectivity. The third section discusses the functional concept of cultivation, focusing on the fact that in Confucian theories the terms “cultivation” and “body” are always combined to form the concept of “self-cultivation.” Moreover, Confucian thinkers tend to discuss the effort of self-cultivation in the context of a body-mind continuum. Indeed, they often use orientational metaphors in order to describe the efforts entailed by cultivation. The fourth section analyzes the linguistic setting and context of the functional concept of transformation within Confucian philosophy of the concrete self. The term “transformation” indicates clearly that Confucian philosophy is a transformative philosophy. The fifth section analyzes the functional concept of nurture, stressing that Confucius’ two greatest followers, Mencius and Xunzi, represent two opposed approaches to nurturing. Mencius stresses that one should undertake the effort of “nurturing qi,” that is, produce culture through natural cultivation, while Xunzi advocates artificially instilling culture in order to discipline, tame, and order nature. Mencius and Xunzi both turn to the container metaphor in their discussions of self-cultivation. The article concludes that the various cultivation activities advocated by these two disparate Confucians are based on two assumptions: the self coincides with the physical body, and the physical self is steeped in and interactive with the cultural values of society. In sum, the functional concept of self-cultivation is an important pillar of Confucian theories of self-cultivation. (shrink)
