Marianne Dashwood is a fictional character in the Jane Austen novel Sense and Sensibility. The 16-year-old second daughter of Mr. and Mrs. Henry Dashwood, she embodies the "sensibility" of the title, as opposed to her elder sister Elinor’s "sense".
She embraces spontaneity, excessive sensibility, love of nature, and romantic idealism: Marianne weeps dramatically when their family must depart from “dear, dear Norland,” and later in the book, exclaims, “Oh! with what transporting sensations have I formerly seen them fall! How have I delighted, as I walked, to see them driven in showers about me by the wind! What feelings have they, the season, the air altogether inspired! Now there is no one to regard them. They are seen only as a nuisance, swept hastily off, and driven as much as possible from the sight.” At which the cooler Elinor replies quietly, “It is not everyone who has your passion for dead leaves.” And later when she hears Sir John Middleton’s account of Willoughby, her eyes sparkle, and she says, “That is what I like; that is what a young man ought to be. Whatever be his pursuits, his eagerness in them should know no moderation, and leave him no sense of fatigue.”
When Marianne is helped by the dashing John Willoughby, she falls deeply and sincerely in love with him, abhorring all society's demands, and ignoring her sister’s rational warnings that her impulsive behavior leaves her open to gossip and innuendo. His painful spurning of her, and the shocking discovery of his dissipated character, finally causes her to recognize her misjudgment of him. She acts exactly as she feels, thus making herself and everyone around her miserable when Willoughby leaves her, as opposed to her sister, who keeps the secret of Edward’s prior engagement to another in quiet, thoughtful composure.
Marianne treats her acquaintances in general with inattention and sometimes, contempt, recoiling from vulgarity, even when it is accompanied by good nature (like Mrs. Jennings), treating her selfish half-brother and his snobbish wife with disgust, totally ignoring the grave Colonel Brandon because of his age and a former love, and making no attempt at civility to insipid Lady Middleton. The people she does love, however, she loves with warmth that leaps over all barriers—even barriers of propriety. Her sorrows, her joys, her antipathy and her love will have no moderation—no concealing.
Marianne’s form is “not so correct as her sister’s,” but “more striking,” and her features are all good, her face is “lovely”: her skin is very brown, but from its transparency, “her complexion was uncommonly brilliant,” and in her eyes there is “a life, a spirit, an eagerness which could hardly be seen without delight.”
