2. Cicero, De Or. 3.198


Verum ut in versu vulgus, si est peccatum, videt, sic, si quid in nostra oratione claudicat, sentit; sed poetae non ignoscit, nobis concedit: taciti tamen omnes non esse illud, quod diximus, aptum perfectumque cernunt.

But as the common people notice where there is anything faulty in a verse, so they are sensible of any lameness in our language; but they grant the poet no pardon; to us they show some indulgence; but all tacitly discern that what we have uttered has not its peculiar propriety and finish.
