Some Trinitarians, such as Thomas Aquinas, wish to claim that God is mereologically simple; that is, God has no parts distinct from Himself. In this paper, I present Simple Trinitarianism, a view that takes God to be simple but, diverging from Aquinas, does not identify the Father, Son, and Holy Spirit with anything in our ontology. Nonetheless, Simple Trinitarians would like Trinitarian sentences to be true; thus, they must give a non-standard semantics for those sentences. I will focus on one (...) possible semantics a Simple Trinitarian may give: taking Trinitarian claims to be translatable into feature-placing sentences, which posit property instantiation without requiring commitment to any objects that instantiate those properties.

Perichoresis, or “mutual indwelling,” is a crucial concept in Trinitarian theology. But the philosophical underpinnings of the concept are puzzling. According to ordinary conceptions of “indwelling” or “being in,” it is incoherent to think that two entities could be in each other. In this paper, I propose a mereological way of understanding “being in,” by analogy with standard examples in contemporary metaphysics. I argue that this proposal does not conflict with the doctrine of divine simplicity, but instead affirms it. I (...) conclude by discussing how mutual indwelling relates to the concepts of unity and identity. (shrink)

I endorse Composition as Identity, broadly and loosely understood as the thesis that a composite whole is nothing over and above its parts, and the parts nothing over and above the whole. Thus, given an object, x, composed of n proper parts, y1, ..., yn, I feel the tension between my Quinean heart and its Lewisian counterpart. I feel the tension between my obligation to countenance n+1 things, x and the y’s, each of which is a distinct portion of reality, (...) and my inclination to count just 1 thing, x, or just n things, the y’s, the former encompassing the same amount of reality as the latter. This paper is an attempt to reconstruct this tension and to explain it away without forgoing the intimate link between counting and countenancing. (shrink)
