One trait in the philosopher's character we can assume is his love of the knowledge that reveals eternal reality, the realm unaffected by change and decay. He is in love with the whole of that reality, and will not willingly be deprived even of the most insignificant fragment of it - just like the lovers and men of ambition we described earlier on.
By education I mean that training in excellence from youth upward which makes a man passionately desire to be a perfect citizen, and teaches him to rule, and to obey, with justice. This is the only education which deserves the name.
