Interesting thoughts, and well-worth considering. I believe one of the "controversies" between the Plotinian view and Iamblichus revolved around whether the soul fully descends into the body--in Plotinus it seems the soul at some level is yet apart from the body, whereas (if I understand correctly) for Iamblichus, the full descent of the soul is essential for the reascent. (I acknowledge that I may be entirely off base with this...)

These disagreements among the Platonists, though, shouldn't obscure their agreements elsewhere. And in all events, may the Divine Light illuminate the way...
