Cicero, de Amicitia 23-24
“The fact is that if you remove the ties of goodwill from our world, no house or city can stand tall nor can even agriculture persist! If this is less intelligible, one can perceive how powerful friendship and harmony are from the impact of disagreements and disharmony. What house is so stable or what state is so strong that it cannot be upended by hatred and division?”
Quod si exemeris ex rerum natura benevolentiae coniunctionem, nec domus ulla nec urbs stare poterit, ne agri quidem cultus permanebit. Id si minus intellegitur, quanta vis amicitiae concordiaeque sit, ex dissensionibus atque discordiis percipi potest. Quae enim domus tam stabilis, quae tam firma civitas est, quae non odiis et discidiis funditus possit everti?
Plato, Euthyphro 7c
“So if we were disagreeing about whether something was bigger or smaller, we’d turn to actual measurement to resolve our disagreement?”
Οὐκοῦν καὶ περὶ τοῦ μείζονος καὶ ἐλάττονος εἰ διαφεροίμεθα, ἐπὶ τὸ μετρεῖν ἐλθόντες ταχὺ παυσαίμεθ’ ἂν τῆς | διαφορᾶς;
Cicero, de Finibus 4. 22
“If we dispute about a fact, Cato, you and I can have no disagreement! There’s no difference between what you believe and I do when we compare the facts themselves once the words have been changed.”
Si de re disceptari oportet, nulla mihi tecum, Cato, potest esse dissensio; nihil est enim de quo aliter tu sentias atque ego, modo commutatis verbis ipsas res conferamus
