The Mereology of Latin Trinitarianism
According to one version of the Christian doctrine of the Trinity, each of the three divine persons is wholly God. In this paper, I consider whether there is a mereological model which is compatible with this doctrine. I argue that any such model will be incompatible with the axioms of classical mereology. I outline several alternative non-classical mereological models which have some claim to compatibility with the doctrine, and show how they deviate from classical mereology. Ultimately, I suggest that the model which is most clearly compatible with the doctrine is one which allows for two non-identical objects to be improper parts of one another. In the last part of the paper, I consider whether the deviations from classical mereology that this model involves can be motivated independently of theological considerations. I argue that they can.
