This chapter describes in detail the different yet related conceptions of eudaimonia (flourishing, happiness) found in the writings of Kongzi (Confucius), Zhuangzi (a leading Daoist), and the neo-Confucians, all of which, to varying extents and in different ways, embrace the oneness hypothesis and its characteristic moral imperative to care more extensively and fully for the world. It sketches the form of a modern version of the neo-Confucian account of oneness and explores the implications of such a view for contemporary attempts to describe the sources of human happiness. It makes the case for reading all of the Chinese philosophical conceptions of joy it engages as objective claims in the sense that they are not reducible solely to subjective psychological states and shows, through close and careful readings of the texts, that part of the joy they esteem and promote consists in giving oneself over to some larger project or whole.
