Sallust, Bellum Catilinae X:
“At first the desire of power, then the desire of money increased; these were effectively the material of all evils, because avarice overturned faith, probity, and all other noble arts; in their place, it taught men to be arrogant and cruel, to neglect the gods, and to consider all things for sale. Ambition compelled many men to become liars; to hold one thing hidden in the heart, and the opposite thing at the tip of one’s tongue; to judge friends and enemies not in objective terms, but by reference to personal gain; and finally, to make a good appearance rather than to have a good mind. As these vices first began to increase, they were occasionally punished; but afterward, once the contagion had spread like a plague, the state as a whole was altered, and the government, once the noblest and most just, was made cruel and intolerable.”
Igitur primo imperi, deinde pecuniae cupido crevit: ea quasi materies omnium malorum fuere. Namque avaritia fidem, probitatem ceterasque artis bonas subvortit; pro his superbiam, crudelitatem, deos neglegere, omnia venalia habere edocuit. 5 Ambitio multos mortalis falsos fieri subegit, aliud clausum in pectore, aliud in lingua promptum habere, amicitias inimicitiasque non ex re, sed ex commodo aestumare magisque voltum quam ingenium bonum habere. 6Haec primo paulatim crescere, interdum vindicari; post, ubi contagio quasi pestilentia invasit, civitas inmutata, imperium ex iustissumo atque optumo crudele intolerandumque factum.
