It is my task, therefore, and that of your other friends, to speak and to write in such fashion as may be likely to incite you to strive eagerly after those things which even now you do in fact desire: and you it behooves not to be negligent, but as at present so in the future to pay heed to yourself and to discipline your mind that you may be worthy of your father and of all your ancestors. For though it is the duty of all to place a high value upon wisdom, yet you kings especially should do so, who have power over very many and weighty affairs.
