text: I shall indeed arrange for you, in careful order and narrow compass, the notes which you request. But consider whether you may not get more help from the customary method than from that which is now commonly called a "breviary," though in the good old days, when real Latin was spoken, it was called a "summary." The former is more necessary to one who is learning a subject, the latter to one who knows it. For the one teaches, the other stirs the memory. But I shall give you abundant opportunity for both. A man like you should not ask me for this authority or that; he who furnishes a voucher for his statements argues himself unknown. I shall therefore write exactly what you wish, but I shall do it in my own way; until then, you have many authors whose works will presumably keep your ideas sufficiently in order. Pick up the list of the philosophers; that very act will compel you to wake up, when you see how many men have been working for your benefit. You will desire eagerly to be one of them yourself. For this is the most excellent quality that the noble soul has within itself, that it can be roused to honourable things.
