The One and the Good

Augustine follows Plato, in the Timaeus, by attributing mathematical structures to the process of creation.  So, his deity is subject to the Euthyphro-like question--do those structures express divine nature, or, is his God, too, governed by them?  In either case, even if that deity is richer than 'the One' of Platonism, Augustine clearly shares with that doctrine the thesis that Multiplicity is ontologically inferior to Unity.  Now, there is nothing in everyday experience that attests to either that ordering, or its inverse.  In other words, the superiority accorded in these systems to the One, with respect to the Many, is arbitrary.  Thus, Augustinian Morality inherits from Platonism the prejudice that associates 'the Good' with 'the One'.
