Enneads II.9: Against the Gnostics; or, That the Creator and the World are Not
Gnostic Additions to Platonism Are Their Poorest Doctrines
If from the doctrines of the (Gnostics) we remove what they have borrowed from the teachings of the ancients, their remaining additions will be discovered as very unfortunate. Their polemic against (Greek philosophy) consists of an introduction of a great number of genealogies, and destructions, blaming the intercourse of the soul with the body, complaining of the universe, criticising its administration, identifying the demiurgic creator (that is, Intelligence) with the universal souls.
THE UNIVERSAL SOUL MAY NOT BE JUDGED BY THE HUMAN STANDARD.
7. Elsewhere we have demonstrated that this world never began, and will never end; and that it must last as long as the intelligible entities. We have also shown, and that earlier than these (Gnostics), that the soul’s intercourse with the body is not advantageous to her. But to judge the universal Soul according to ours is to resemble a man who would blame the totality of a well governed city by an examination limited to the workers in earth or metal.
