Apuleius, Apologia 7
“I have just noticed certain people here barely containing their laughter, probably because that last speaker was viciously attacking oral health and using the word “dentifrice” with as much anger as no one has ever used for “poison”. Why not? A Philosopher must dismiss no crime, allow nothing corrupt associated with himself, suffer no part of his body to ever be messy or smelly, especially his mouth, something people use openly and obviously all the time whether they try to kiss someone, or attempt to have a conversation, address a large group, or offer prayers in a temple.
Speech leads nearly every human deed and, as the foremost poet says, it begins “at the barrier of the teeth”. Consider someone of fairly elevated speech: he would likely say in his own way that someone who cares about speaking must attend to his mouth beyond the rest of his body because it is the entryway of the mind, the door of speech, the assembly-hall of thoughts.
For my part, I can say that nothing is less fitting to a free person who is educated well than a filthy mouth. The mouth is in that elevated part of the human body, easy to see, needed for speech. In animals, whether wild or domesticated, the mouth is lower and pointed toward feet, near food and footprints. An animal’s mouth is rarely seen except when they are dead or annoyed into biting. For a human, there is nothing you see consider more clearly either when silent or speaking.”
Vidi ego dudum vix risum quosdam tenentis, cum munditias oris videlicet orator ille aspere accusaret et dentifricium tanta indignatione pronuntiaret, quanta nemo quisquam venenum. Quidni? Crimen haud contemnendum philosopho, nihil in se sordidum sinere, nihil uspiam corporis apertum immundum pati ac foetulentum, praesertim os, cuius in propatulo et conspicuo usus homini creberrimus, sive ille cuipiam osculum ferat, seu cum quiquam sermocinetur, sive in auditorio dissertet, sive in templo preces alleget. Omnem quippe hominis actum sermo praeit, qui, ut ait poeta praecipuus, dentium muro proficiscitur. Dares nunc aliquem similiter grandiloquum: diceret suo more cum primis cui ulla fandi cura sit impensius cetero corpore os colendum, quod esset animi vestibulum et orationis ianua et cogitationum comitium. Ego certe pro meo captu dixerim nihil minus quam oris illuviem libero et liberali viro competere, est enim ea pars hominis loco celsa, visu prompta, usu facunda. Nam quidem feris et pecudibus os humile est et deorsum ad pedes deiectum, uestigio et pabulo proximum; nunquam ferme nisi mortuis aut ad morsum exasperatis conspicitur: hominis vero nihil prius tacentis, nihil saepius loquentis contemplere.
