Mr. Bennet is the patriarch of the Bennet household—the husband of Mrs. Bennet and the father of Jane, Elizabeth, Lydia, Kitty, and Mary. He is a man driven to exasperation by his ridiculous wife and difficult daughters. He reacts by withdrawing from his family and assuming a detached attitude punctuated by bursts of sarcastic humor. He is closest to Elizabeth because they are the two most intelligent Bennets.
Initially, his dry wit and self-possession in the face of his wife’s hysteria make Mr. Bennet a sympathetic figure, but, though he remains likable throughout, the reader gradually loses respect for him as it becomes clear that the price of his detachment is considerable. He is in fact a weak father who, at critical moments, fails his family. In particular, his foolish indulgence of Lydia’s immature behavior nearly leads to general disgrace when she elopes with Wickham. Further, upon her disappearance, he proves largely ineffective. It is left to Mr. Gardiner and Darcy to track Lydia down and rectify the situation. Ultimately, Mr. Bennet would rather withdraw from the world than cope with it.
