Meliboeus, admitting that his wife had spoken well and suitably as to counsellors and counsel in general, prays her to tell him in especial what she thinks of the counsellors whom they have chosen in their present need. Prudence replies that his counsel in this case could not properly be callëd a counselling, but a movement of folly; and points out that he has erred in sundry wise against the rules which he had just laid down. Granting that he has erred, Meliboeus says that he is all ready to change his counsel right as she will devise; for, as the proverb runs, to do sin is human, but to persevere long in sin is work of the Devil. Prudence then minutely recites, analyses, and criticises the counsel given to her husband in the assembly of his friends. She commends the advice of the physicians and surgeons, and urges that they should be well rewarded for their noble speech and their services in healing Sophia; and she asks Meliboeus how he understands their proposition that one contrary must be cured by another contrary. Meliboeus answers, that he should do vengeance on his enemies, who had done him wrong. Prudence, however, insists that vengeance is not the contrary of vengeance, nor wrong of wrong, but the like; and that wickedness should be healed by goodness, discord by accord, war by peace.
