This essay examines the nature of things in early Daoism via the lens of comparative philosophy. Daoism uses ziran 自然 (spontaneity) to express the nature of things. I explore the ziran or spontaneity of the myriad things through the analysis of de 德, sheng 生 (xing 性), and freedom (ziyou 自由). The sections on de 德 and sheng 生 reveal that the spontaneity of things is the ultimate reality, which contains the oneness of one and many, essence and appearance, change and changelessness. The section on freedom revolves around two essential questions in metaphysics: What are things? What is the relation between things and humans? Different from the motto of modern metaphysics, “humans prescribes laws to nature”, early Daoism believes that human existence belongs to the constant ziran. I call this “nature prescribes laws to humans”.
