Aeneas Silvius Piccolomini, de Liberorum Educatione:
“There is the greatest number of those who pamper and arrange their hair, who drink at the baths, who dine out with unseemly zeal, who serve unlawful profit and pleasure. There are few who abstain from these things. Let it not be that we imitate the former; let us avoid them. How many there are, who degrade the Latin language! In place of the word ‘love’ (amare) and ‘to chase after ladies with carnal desire,’ the people of this land say hovizare. They call ‘the expenses incurred on a journey’ cerealia. When they want to say that someone will come, they do not say, ‘he will come,’ but ‘the coming will be soon.’ What then? Shall we follow these people (because they are the majority) and adopt our mode of speaking from the mob? Let this error go away. For indeed, though something faulty has settled in the minds of ever so many people, it should not be accepted as a rule of speech, because good morals – not vice – make for linguistic correctness. Just as it is proper, in life, to call upon and imitate the custom of the good, so too in the field of speech, we must call upon and imitate the established usage of the learned.”
Maximus est eorum numerus, qui comas nutriunt et in gradus frangunt, qui perpotant in balneis, qui summo studio cenas sectantur, qui lucris illicitis, qui libidini serviunt; pauci, qui ab his abstinent. Absit, ut illos imitemur; istos fugiamus. Quam multi sunt, qui verba Latina depravant! Pro eo, quod est ‘amare’ atque ‘insequi Veneris cupiditate feminas,’ ‘hovizare’ huius terrae populus dicit; ‘sumptus qui fiunt ab itinerantibus,’ ‘ceralia’ vocat; quando venturum quemquam significare vult, ipse inquit non ‘veniet,’ sed ‘erit cito venire.’ Quid igitur? Sequemurne istos, quia plurimi sunt, et loquendi consuetudinem ex multitudine recipiemus? Facessat hic error. Non enim, quod vitiose quamvis multis insiderit, pro regula sermonis accipiendum erit, quia non vitia sed mores boni consuetudinem faciunt. Sicut ergo vivendi consensum bonorum, sic et loquendi consonantiam eruditorum appellare et imitari consuetudinem oportebit.
