Cicero, De Natura Deorum, 3.77–78
“These kind of things belong to poets; we, moreover, want to be philosophers, masters of facts not fables. And yet, these gods of poetry, if they know that these things would be ruinous for their children, would be considered to have sinned in conferring a favor.
It is just as if, according to that thing which Aristo of Chios used to say, that philosophers hurt their audiences when the things they say well are interpreted badly (for it was possible still to leave Aristippus’ school as a profligate or Zeno’s school bitter and angry).
If it is this way, and those who have heard them leave with twisted minds because they understand the philosophers’ arguments incorrectly, then it befits philosophers more to be quiet than cause their audiences harm. In this way, if people pervert the capacity for reason which was given by the gods to provide good council and used it instead for fraud and harm, then it would have been better if it had not been given to the human race at all.”
Poetarum ista sunt, nos autem philosophi esse volumus, rerum auctores, non fabularum. Atque hi tamen ipsi di poetici si scissent perniciosa fore illa filiis, peccasse in beneficio putarentur. Ut si verum est quod Aristo Chius dicere solebat, nocere audientibus philosophos iis qui bene dicta male interpretarentur (posse enim asotos ex Aristippi, acerbos e Zenonis schola exire), prorsus, si qui audierunt vitiosi essent discessuri quod perverse philosophorum disputationem interpretarentur, tacere praestaret philosophos quam iis qui se audissent nocere: sic, si homines rationem bono consilio a dis immortalibus datam in fraudem malitiamque convertunt, non dari illam quam dari humano generi melius fuit. Ut, si medicus sciat eum aegrotum qui iussus sit vinum sumere meracius sumpturum statimque periturum, magna sit in culpa, sic vestra ista providentia reprehendenda, quae rationem dederit
