Quinctilian says: "Sunt quidam, nisi institeris, remissi; quidam imperio indignantur: quosdam continet metus, quosdam debilitat: alios continuatio extundit, in aliis plus impetus facit. Mihi ille detur puer, quem laus excitet, quem gloria juvet, qui victus fleat; hic erit alendus ambitu, hunc mordebit objurgatio, hunc honor excitabit; in hoc desidiam nunquam verebor."
A noble emulation will always keep him in exercise, a reprimand will touch him to the quick, and honour will serve instead of a spur. We need not fear that such a scholar will ever give himself up to sullenness." Mihi ille detur puer, quem laus excitet, quem gloria juvet, qui virtus fleut. Hic erit alendus ambitu: hunc mordebit objurgetio; hunc honor excitabit; in hoc desidium nunquam verebor.
