Now Socrates, whenever he saw several persons assembled, would cry out most bravely and frankly with indignant rebuke and censure, “Whither are you drifting, men? Are you quite unaware that you are doing none of the things that you should do, in concerning yourselves with money and trying to get it in any way and every way, in order that you may not only have it in abundance yourselves, but may bequeath still more of it to your children? Yet the children themselves — aye, and earlier, yourselves, their fathers — you have all alike neglected, since you have found no education and no mode of life that is satisfactory, or even profitable, for man, which, if acquired, will enable you to use your money rightly and justly, instead of harmfully and unjustly, and to treat without hurt, not only yourselves, whom you should have considered of more value than wealth, but also your sons and daughters and wives and brothers and friends, even as they should treat you.
17 “But, pray, is it by learning from your parents to play the lyre and to wrestle, to read and write, and by teaching your sons these things that you think that your city will be inhabited by more disciplined and better citizens? And yet if one were to bring together all the cithara players and gymnastic masters and schoolmasters who have the best knowledge of their respective subjects, and, if you should found a city with them or even a nation, just as you at one time colonized Ionia, what sort of a city do you think it would be, and what the character of its citizens? Would not life be much worse and viler than it is in that city of shopkeepers in Egypt, where all shopkeepers settle, both men and women alike? Will not a much more ridiculous society be made by these teachers of your children of whom I speak — I mean the gymnastic masters, the cithara players, and the schoolmasters, including the rhapsodists and the actors?”
