 Two important points follow. First, existence is seen not in terms of abstract being but rather as sheng 生: life, growth, birth, vitality. The fundamental role of sheng appears explicitly in the “Xici” commentary on the Yi Jing, which says that the foundation of the Changes is shengsheng, “generating and generating”, “growing and growing”, “living and living”, or “natura naturans” (Gao Heng 1998: 388). This phrase inspired the famous description of nature as shengsheng buxi 生生不息: generating, generating, never ceasing! It is sometimes said that Chinese philosophy lacks ontology (and thus metaphysics) because philosophers were never concerned with being as such. It is more accurate to say that Chinese philosophers took dynamic organization as implicit in the very nature of being, rather than positing an external source for motion and order. This means that ontology is also cosmology, even biology.
