The One and The First

On the basis of Parmenides' The One, Motion and Multiplicity are irreal.  In contrast, on the basis of Plotinus' The One, which he conceives as the source of Emanation, Multiplicity is not irreal, but remains less real than Oneness.  Thus, Plotinus' more significant break with Parmenides is to conceive Motion, i. e. the process of Emanation, as fully real, which Bergson seems to appreciate better than most of his modern peers.  Still, the concept 'one' is static and self-contained, and, therefore, remains problematic as the source of a dynamic process.  Instead, a more appropriate characterization of Plotinus' principle is 'The First'.
