Yue reconstructs Aristotle's project and argument in the tenth book of the Metaphysics as an Aristotelean investigation into the per se attributes of being, qua being. These attributes include unity, identity, difference. Yue argues that they can be best understood as the consequences of quantification, and they can be characterized accordingly. Yue is motivated by how these attributes are important to Aristotle's Metaphysical theory, and to metaphysics conceived as an Aristotelean science in related works, how they are critical to the principle of non-contradiction/excluded middle, and how they imply an internal complexity to the notion of existence and the existential quantifier. Yue articulates the philosophical difficulty these attributes pose and how Aristotle manages these difficulties by pursuing a specific reductive project. The resulting picture is a conceptually rich theory of Unity, Sameness, Difference, without relying on reifying these notions and other such ultimately unconvincing philosophical gymnastics.
