A Wholesome Trinity

According to the Neoplatonic philosopher Proclus, a whole can exist in three ways: before the parts, composed of parts, or in the part. To unify the diverging scholarly interpretations of this idea, this paper re-examines Proclus’ well-known definition of the three wholes in his Elements of Theology, analyses lesser-known arguments from his Platonic Theology, and discusses two examples of Proclus’ theorem from the Commentary on Plato’s Timaeus.
