5 I know that I must offend large numbers who will be angry with my criticisms as aimed at their own deficiencies. Yet such anger does but show an uneasy conscience and they will pass a far severer sentence on themselves than on me. For I shall not mention names; or copy the licence of the old comedy which criticized individuals. Wise men and wise women will try to hide or rather to correct whatever they perceive to be amiss in them; they will be more angry with themselves than with me, and will not be disposed to heap curses upon the head of their monitor. For he, although he is liable to the same charges, is certainly superior in this that he is discontented with his own faults.
