6 From this then, and from every other circumstance, it is plain, that nothing of this man's is human, but divine and heavenly are the lessons which come to us by this divine soul. For we shall observe not sounding sentences, nor magnificent diction, nor excessive and useless order and arrangement of words and sentences, (these things are far from all true wisdom,) but strength invincible and divine, and irresistible force of right doctrines, and a rich supply of unnumbered good things. For their over-care about expression was so excessive, so worthy of mere sophists, or rather not even of sophists, but of silly striplings, that even their own chief philosopher introduces his own master as greatly ashamed of this art, and as saying to the judges, that what they hear from him shall be spoken plainly and without premeditation, not tricked out rhetorically nor ornamented with (fine) sentences and words; since, says he, it cannot surely be becoming, O men, that one at my age should come before you like a lad inventing speeches. And observe the extreme absurdity of the thing; what he has described his master avoiding as disgraceful, unworthy of philosophy and work for lads, this above all he himself has cultivated. So entirely were they given up to mere love of distinction.
And as, if you uncover those sepulchers which are whitened without you will find them full of corruption, and stench, and rotten bones; so too the doctrines of the philosopher, if you strip them of their flowery diction, you will see to be full of much abomination, especially when he philosophizes on the soul, which he both honors and speaks ill of without measure. And this is the snare of the devil, never to keep due proportion, but by excess on either hand to lead aside those who are entangled by it into evil speaking. At one time he says, that the soul is of the substance of God; at another, after having exalted it thus immoderately and impiously, he exceeds again in a different way, and treats it with insult, making it pass into swine and asses, and other animals of yet less esteem than these.
But enough of this; or rather even this is out of measure. For if it were possible to learn anything profitable from these things, we must have been longer occupied with them; but if it be only to observe their indecency and absurdity, more than requisite has been said by us already. We will therefore leave their fables, and attach ourselves to our own doctrines, which have been brought to us from above by the tongue of this fisherman, and which have nothing human in them.
