text: You should keep learning as long as you are ignorant, – even to the end of your life, if there is anything in the proverb. And the proverb suits the present case as well as any: "As long as you live, keep learning how to live." For all that, there is also something which I can teach in that school. You ask, do you, what I can teach? That even an old man should keep learning. But I am ashamed of mankind, as often as I enter the lecture-hall. On my way to the house of Metronax I am compelled to go, as you know, right past the Neapolitan Theatre. The building is jammed; men are deciding, with tremendous zeal, who is entitled to be called a good flute-player; even the Greek piper and the herald draw their crowds. But in the other place, where the question discussed is: "What is a good man?" and the lesson which we learn is "How to be a good man," very few are in attendance, and the majority think that even these few are engaged in no good business; they have the name of being empty-headed idlers. I hope I may be blessed with that kind of mockery; for one should listen in an unruffled spirit to the railings of the ignorant; when one is marching toward the goal of honour, one should scorn scorn itself.
