Answer:
The old woman told the knight that it is better to have a wife who is old and faithful instead of a beautiful wife who cheats. As far as riches or poverty is concerned, the rich have money but their worries did not end. Instead, their greed for finer better things increase while the poor are content with what they have.
Step-by-step explanation:
Geoffrey Chaucer's "Canterbury Tales" includes "The Wife of Bath's Tale" from where the excerpt can be found. The tale of the Old Woman is told by the Wife, emphasizing on the themes of wealth and beauty.
When the knight criticizes the old woman for being so ugly and poor, she in return told her that beauty and riches are not the best of qualities a man needs. For the nobles of men have virtues that encompasses wealth and physical beauty. She also told him that an ugly wife is far more better than a beautiful one, for he will not have the stress of having a cheating wife. And for wealth, men who are poor have the most happy life than those who are rich. Riches only increases want and greed. Even "Crist wol, we clayme of him our gentillesse, Nat of our eldres for hir old richesse". She adds "Iesus, hevene king, Ne wolde nat chese a vicious living."
Her arguments are convincing for they are true. She also managed to make him understand it and thus, lead a happy life with him.
