Convivio (III, xi, 10)

(10) Né si dee chiamare vero filosofo colui che è amico di sapienza per utilitade, sì come sono li legisti, medici e quasi tutti religiosi, che non per sapere studiano ma per acquistare moneta o dignitade; e chi desse loro quello che acquistare intendono, non sovrastarebbero allo studio. (10) Nor should we give the name of true philosopher to anyone who is a friend of wisdom for the sake of utility, as are jurists, physicians, and almost all those belonging to religious orders, who study not in order to gain knowledge but to secure financial rewards or high office; and if anyone were to give them what they seek to gain, they would not persevere in their study.
