Sense and Sensibility represents neoclassical, dualistic moral world where the values of reason and restraint will finally become victorious over the impulsive, romantic sensibility. Not only that, she makes a severe satire of the hypocrisies of the eighteenth century society where the aristocrats are praised and indirectly influences young minds, not to value love but to betray it just for the sake of wealth. In the novel, Lucy and Willoughby symbolize this type of people of the society.
The novel in an implicit way depicts the gaps that occur between language and behavior, feeling and action. For Marianne the relationship is to be found on the unmediated openness of one freely expressive heart to another. But for Elinor marriage is a first social contract. This social contract is first mediated by a language, which preserves a rational and decorous civilization as a stay against humankind's baser instincts. The novel represents the two sisters who had a different approach to love and relationships. Marianne has chosen an impulsive and abstractly romantic path to life, love and relationship. Her chosen partner Willoughby is also unbelievably dashing handsome. But Willoughby turns out to be a wolf in sheep's clothing: he betrays Marianne. By showing the tragic collapse of Marianne-Willoughby love relation, Jane Austen is trying to warn to those who tend to find love through unrestricted impulse. Through this failure of love of Marianne, Austen is expressing her dissatisfaction towards any individual attempt to form any relationship basing on abstract emotion.
