Arnobius — Against the Nations 2.10
10.1. Let us grant the very chiefs and fathers of the aforesaid opinions—do they not say what they say as trusted to their own suspicions? For did Heraclitus see that things come about by conversions of fires, Thales by condensation of waters, Pythagoras that numbers combine, Plato incorporeal forms, Democritus collisions of atoms? Or those who claim that nothing at all can be grasped—do they know whether what they say is true, so that they understand the very pronouncement they define to be of truth?
2. Since therefore you have nothing ascertained and known, and you affirm all those things which you write and comprehend in thousands of books with credulity as guide, what judgment is this so unjust, that you ridicule our faith which you see yourselves have in common with our credulity?
3. "But you believe wise men and those instructed in all kinds of disciplines." — Yes, those who know nothing and pronounce nothing as one, who wage wars with opponents for their opinions and always duel with hostile obstinacy, who when each undermines, destroys, and overturns the other's decrees, have made all things uncertain and have shown from the very disagreement that nothing can be known.
Latin
10.1. Ipsi demus principes et praedictarum patres sententiarum, nonne ea quae dicunt suis credita suspicionibus dicunt? Vidit enim Heraclitus res ignium conversionibus fieri, concretione aquarum Thales, Pythagoras numeros coire, incorporales formas Plato, individuorum Democritus concursiones? Aut illi, qui autumant nihil posse omnino conprehendi, an sit verum quod dicunt sciunt, ut ipsum quod definiunt veritatis esse intellegant pronuntiatum?
2. Cum igitur comperti nihil habeatis et cogniti omniaque illa quae scribitis et librorum comprehenditis milibus credulitate adseveretis duce, quaenam haec est iudicatio tam iniusta, ut nostram derideatis fidem, quam vos habere conspicitis nostra in credulitate communem?
3. ''Sed sapientibus vos viris omnibusque instructis disciplinarum generibus creditis''. - Nempe illis, qui nihil sciscunt nec pronuntiant unum, qui pro suis sententiis bella cum adversantibus conserunt et pervicacia semper digladiantur hostili, qui cum alter alterius labefactant destruunt convelluntque decreta, cuncta incerta fecerunt nec posse aliquid sciri ex ipsa dissensione monstrarunt.
