Modesto tamen et circumspecto iudicio de tantis viris pronuntiandum est, ne, quod plerisque accidit, damnent quae non intellegunt. - Quintilian

For it is an ordinance of nature that nothing great can be achieved in a moment, and that all the fairest tasks are attended with difficulty, while on births as well she has imposed this law, that the larger the animal, the longer should be the period of gestation.

Nihil enim rerum ipsa natura voluit magnum effici cito, praeposuitque pulcherrimo cuique operi difficultatem: quae nascendi quoque hanc fecerit legem, ut maiora animalia diutius visceribus parentis continerentur.

We should not speak so that it is possible for the audience to understand us, but so that it is impossible for them to misunderstand us.
