The conclusions of Jane Austen's novels are invariably ironic devices for the final summary of themes and characters. This role is illuminated by three main elements of all the conclusions. First, the novelist parodies the predictability of sentimental “happy endings” in much popular fiction. This accounts for the exaggerated self-consciousness with which she approaches the mechanics of concluding her own narratives, a self-consciousness that seems on the surface to contradict Jane Austen's well-known dislike of unrealistic plots. Second, she subverts the canons of poetic justice that are integral to most happy endings: instead of allocating “rewards” and punishment in accordance with ideal conventions, Jane Austen exposes the prevailing social norms that frequently undermine and replace traditional ideals. Finally, she replaces the arbitrary endings of poetic justice with the logical evolution of character and theme. Each character “punishes” or “rewards” himself, in keeping with his frequently unreliable sense of right and wrong. These features are particularly useful in a much-needed revaluation of Mansfield Park, for they demonstrate that it is not the didactic work described in traditional criticism. Thus Jane Austen's comic conclusion is a consistent device for the realistic, rather than didactic, analysis of character and society.
