THE GNOSTICS MAY WELL BORROW FROM THE GREEKS, BUT SHOULD NOT DEPRECIATE THEM.
Instead of besmirching the reputation of divine men,[316] the (Gnostics) should interpret the doctrines of the ancient sages in a friendly way, borrowing from them such as they are right in professing, as, for instance, the immortality of the soul, the existence of the intelligible world, and of the first Divinity (who is the Good), the necessity for the soul to flee from intercourse with the body, and the belief that separation of the soul from body is equivalent to a return from generation to "being."[317] They do well indeed if they borrow these ideas from Plato, for the purpose of developing them. They are even at liberty to express any opinion they please in diverging from his views; but their own doctrine should not be established in the minds of their followers by insults and sarcasms against Greek sages. They could only do so by demonstrating the propriety of their distinctive tenets, whenever they differ from those of the ancient philosophers, and by expounding their own tenets with a really philosophic reserve and equanimity. Even when they controvert a system they are still bound to consider nothing but the truth, without any attempt at self-glorification, either by attacking men whose teachings have long since been approved by worthy philosophers, or by claims of superiority to the latter. For that which the ancients taught on the subject of the intelligible world will always be considered as the best and wisest by all who do not permit themselves to be misled by the errors that to-day mislead so many.[318]
