One, Many, Dualism

Perhaps unwittingly, Neoplatonism illustrates how Parmenides arrives at his The One.  Beginning with the process of Emanation, in which the development of multiple rays from a single source is a continuum, the Neoplatonists isolate the source, and characterize it as The One, thereby severing Unity from Multiplicity.  Likewise, Parmenides' ostensible Monism is actually a suppressed Dualism.  Now, while much of the subsequent tradition does not recognize so radical a suppression, it still inherits a One-Many Dualism that includes an account of the One influencing the Many.  Typically, though, the account is merely nominal, e. g. 'individuation', 'instantiation', even the 'ingression' of the avowed non-Dualist Whitehead, lacking any coherent explanation of how the divide is bridged.  But, once the full genealogy of the One-Many relation is considered, it is clear that the reason why such an explanation continues to be lacking is that the problem that it would solve is itself just as merely nominal as the various solutions.  Similarly, what Zeno ultimately demonstrates is the non-existence of not Multiplicity, but of the severing that separates Multiplicity from The One to begin with.
