[14]
But1 the strongest challenge to your task you will find in yourself, if only you consider it monstrous that the worse should rule the better,2 and that the more foolish should give orders to men of greater wisdom; for the more vigorously you condemn folly in others, the more diligently will you train your own understanding.
1 The passage here to 39 is quoted in a somewhat abbreviated form in Isoc. 15.73.
