John Knightley
John Knightley, the husband of Emma Woodhouse's elder sister Isabella, is a tall, gentleman-like, and very clever man rising in his profession as a lawyer, with a domestic and respectable private character. Yet his reserved manners prevent him from being generally pleasing, and he is capable of being sometimes out of humour. His temper is not his great perfection; indeed, with such a worshipping wife as Isabella, it is hardly possible that any natural defects in it should not be increased. The extreme sweetness of her temper must hurt his. He has all the clearness and quickness of mind which she wants, and he can sometimes act an ungracious, or say a severe thing. He is not a great favourite with his fair sister-in-law Emma, who is quick in feeling the little injuries to Isabella that Isabella never feels herself. Nothing wrong in him escapes her, and she particularly resents his occasional want of respectful forbearance towards her father, Mr. Woodhouse, whose peculiarities and fidgetiness sometimes provoke him to a rational remonstrance or sharp retort equally ill-bestowed.
Life and Plot Trajectory
John Knightley's appearances at Hartfield are tied to his family's visits from London, where he lives with Isabella and their five children in Brunswick Square. His professional engagements as a lawyer keep him in town, and he is often the first to leave the country. On the evening of the dinner at Randalls in December, he is in a particularly bad humour, anticipating nothing in the visit that could be worth the purchase of leaving his own fireside in such cold, snowy weather. He spends the drive expressing his discontent, calling the folly of not allowing people to stay comfortably at home the greatest absurdity. At Randalls, he is the one who discovers the ground covered with snow and announces it, taking a rather unfeeling triumph in the situation. He is also the first to suspect Mr. Elton's true intentions, telling Emma directly that Mr. Elton seems to have a great deal of good-will towards her, a warning she dismisses with amusement. Later, when Mr. Weston returns from London on the evening of the Hartfield dinner party, John Knightley is in mute astonishment that a man who might have spent his evening quietly at home after a day of business should set off again to be in mixed company, a circumstance that strikes him deeply.
Key Actions and Objectives
John Knightley's most significant actions are his accurate, often unwelcome, observations. He is the first to suggest to Emma that Mr. Elton's attentions are directed at her, not Harriet Smith, a piece of insight she initially rejects. He also provides the crucial link that leads to Harriet Smith's marriage to Robert Martin. When Robert Martin goes to London on business, John Knightley delivers some papers for his brother, and then asks Martin to join his family party at Astley's. During that visit, Martin finds an opportunity to speak to Harriet and is accepted. John Knightley then reports the proceedings to his brother, who in turn informs Emma. His objective throughout is not to interfere in Emma's matchmaking, but his clear-eyed, unsentimental view of character and situation repeatedly cuts through her self-deceptions.
Relationships and Conflict
John Knightley's relationship with Emma is one of mutual, though not hostile, wariness. He sees through her schemes and is not afraid to voice his opinions, as when he tells her that her manners to Mr. Elton have been encouraging. He is also a devoted husband to Isabella, though his temper is often tried by her excessive solicitude. His most notable conflict is with Mr. Woodhouse, whose hypochondria and fussiness he finds difficult to bear with patience. Emma is particularly sensitive to this, and she often has to intervene to keep the peace. His relationship with his brother George is one of deep, though undemonstrative, affection; they converse easily on matters of law, farming, and family, and John's letter approving of George's engagement to Emma is written with a sensible, brotherly sincerity that Emma herself honours.
Change and Ending
John Knightley does not undergo a dramatic transformation, but his role in the narrative is to provide a consistent, rational counterpoint to Emma's imaginative flights. His final significant act is to facilitate the marriage of Robert Martin and Harriet Smith, an event that resolves one of the novel's central anxieties. He is present at Hartfield for the wedding of Emma and Mr. Knightley, and his approval of the match, though expressed without flourish, is clear. He remains the same clever, reserved, and occasionally sharp man, but his actions ultimately contribute to the happy resolution of the story, proving that his clear-sightedness, however blunt, is a force for good.
Narrative Role and Evaluation
John Knightley functions as a secondary but crucial character whose primary narrative role is to puncture Emma's illusions. He is a flat character in E. M. Forster's sense, built around a single idea of rational, unsentimental observation, but he is instantly recognizable and consistently effective. His sharp tongue and lack of patience with folly make him an uncomfortable presence for Emma, but his judgments are almost invariably correct. He embodies the voice of practical reason and domestic duty, standing in contrast to his brother George's more patient and authoritative guidance. While George Knightley corrects Emma with a view to her moral improvement, John Knightley's corrections are more immediate and less forgiving, serving as a check on her vanity and a reminder of the consequences of her meddling.
