Prop. 113: The whole number of the gods has the character of unity.
For if the divine series (theios arithmos) has for antecedent cause the One (to hen), as the intellective (noeros) series has intelligence and the psychical series has Soul, and if at every level the manifold (plethos) is analogous to its cause, it is plain that the divine series has the character of unity, if the One is god. Now that the One is god follows from its identity with the Good: for the Good is identical with god, god being that which is beyond all things and to which all things aspire, and the Good being the `whence and whether' of all things. Thus if a plurality of gods exist they must have the character of unity. But it is evident that such a plurality in fact exists, inasmuch as every originative cause introduces its proper manifold, which resembles it and is akin to it.
