This article is based on my mereological reconstruction of the Daoist metaphysical system, as presented in the Daodejing. I conceptualize the Dao and you relationship as a relationship between Unrestricted Composition (for any entities, there is a composition that they make) and Restricted Composition (what is an entity is determined by finite composition rules) respectively. This conceptualization, among other things, makes it possible to address the way in which Dao is described as wu—nothingness or non-being. In this article, I will show that Dao as the ultimate reality in Daoist metaphysics is not an ontological nothingness and discuss how this “nothingness characteristic” can be mereologically reconstructed and explained. I will discuss the interpretation of Dao in terms of Mereological Nihilism (according to which there are only mereological simples that do not have parts and are not parts of any complex entities), Unrestricted Composition, and consider an option in which mereology is confined exclusively to relationships between parts. I will also discuss how the nothingness aspect of Dao can be viewed from a stuff ontology perspective, which questions the ontological standing of parts.
