what do you think is the contribution of mr.bennet and mrs.bennet as parents to the development of thier daughters character?

Mr. Bennet is witty and loves books. Unfortunately these don't translate to parenting skills, Mr. Bennet made the mistake of marrying a foolish woman. He takes refuge in his books and seems to want nothing more than to be bothered as little as possible by his family. His indolence leads to the neglect of the education of daughters. Even when Elizabeth warns him not to allow Lydia to go to Brighton because of the moral danger of the situation, he does not listen to her because he does not want to be bothered with Lydia's complaints.

Mrs. Bennet is a foolish and frivolous woman. She lacks all sense of propriety and virtue and has no concern for the moral or intellectual education of her daughters. From the beginning of the novel her sole obsession is to marry off her daughters. She is perfectly happy with Lydia's marriage, and never once censures her daughter for her shameful conduct or for the worry she has caused her family. Her impropriety is a constant source of mortification for the Elizabeth, and the inane nature of her conversation makes her society so difficult to bear that even Jane and Bingley decide to move out of the neighborhood a year after they are married.
