intro
Anyone who without a preconceived thesis to defend reads the De Facie will recognize, I believe, that Plato was Plutarch’s inspiration throughout the dialogue but that Plutarch is himself the true author of the whole work and that, while there is in it a distillation of his wide and varied scientific and philosophical reading, he cannot possibly have composed it by copying out any source or combination of sources. I have tried in the exegetical notes to indicate the parallels which will help the reader to understand the dialogue itself by seeing its relation to the rest of ancient scientific and philosophical thought. Among these parallels some of the most striking are drawn from later writers, especially Neo-Platonists; these I have mentioned not in order to insinuate that they show Plutarch’s direct influence upon those later writers, although many of them certainly were acquainted with him, but because they illuminate the meaning of the Facie and at the same time indicate what may have been contained in some of the philosophical writings known to Plutarch and long since lost to us, and may help to cast some flicker of light upon that obscure and controversial problem, the prehistory of Neo-Platonism.
