Mrs. Bennet is a miraculously tiresome character. Noisy and foolish, she is a woman consumed by the desire to see her daughters married and seems to care for nothing else in the world. Ironically, her single-minded pursuit of this goal tends to backfire, as her lack of social graces alienates the very people (Darcy and Bingley) whom she tries desperately to attract. Austen uses her continually to highlight the necessity of marriage for young women. Mrs. Bennet also serves as a middle-class counterpoint to such upper-class snobs as Lady Catherine and Miss Bingley, demonstrating that foolishness can be found at every level of society. In the end, however, Mrs. Bennet proves such an unattractive figure, lacking redeeming characteristics of any kind, that some readers have accused Austen of unfairness in portraying her—as if Austen, like Mr. Bennet, took perverse pleasure in poking fun at a woman already scorned as a result of her ill breeding.
