Book 2.16

Those animals, urges our opponent, are held to be the most generous who have large capacity for anger. He is mistaken when he holds up creatures who act from impulse instead of reason as patterns for men to follow, because in man reason takes the place of impulse. Yet even with animals, all do not alike profit by the same thing. Anger is of use to lions, timidity to stags, boldness to hawks, flight to doves. What if I declare that it is not even true that the best animals are the most prone to anger? I may suppose that wild beasts, who gain their food by rapine, are better the angrier they are; but I should praise oxen and horses who obey the rein for their patience. What reason, however, have you for referring mankind to such wretched models, when you have the universe and God, whom he alone of animals imitates because he alone comprehends Him? "The most irritable men," says he, "are thought to be the most straightforward of all." Yes, because they are compared with swindlers and sharpers, and appear to be simple because they are outspoken. I should not call such men simple, but heedless. We give this title of "simple" to all fools, gluttons, spendthrifts, and men whose vices lie on the surface.
