The moral theme of Great Expectations is quite simple: affection, loyalty, and conscience are more important than social advancement, wealth, and class. Dickens establishes the theme and shows Pip learning this lesson, largely by exploring ideas of ambition and self-improvement—ideas that quickly become both the thematic center of the novel and the psychological mechanism that encourages much of Pip’s development. At heart, Pip is an idealist; whenever he can conceive of something that is better than what he already has, he immediately desires to obtain the improvement. When he sees Satis House, he longs to be a wealthy gentleman; when he thinks of his moral shortcomings, he longs to be good; when he realizes that he cannot read, he longs to learn how. Pip’s desire for self-improvement is the main source of the novel’s title: because he believes in the possibility of advancement in life, he has “great expectations” about his future.

Ambition and self-improvement take three forms in Great Expectations—moral, social, and educational; these motivate Pip’s best and his worst behavior throughout the novel. First, Pip desires moral self-improvement. He is extremely hard on himself when he acts immorally and feels powerful guilt that spurs him to act better in the future. When he leaves for London, for instance, he torments himself about having behaved so wretchedly toward Joe and Biddy. Second, Pip desires social self-improvement. In love with Estella, he longs to become a member of her social class, and, encouraged by Mrs. Joe and Pumblechook, he entertains fantasies of becoming a gentleman. The working out of this fantasy forms the basic plot of the novel; it provides Dickens the opportunity to gently satirize the class system of his era and to make a point about its capricious nature. Significantly, Pip’s life as a gentleman is no more satisfying—and certainly no more moral—than his previous life as a blacksmith’s apprentice. Third, Pip desires educational improvement. This desire is deeply connected to his social ambition and longing to marry Estella: a full education is a requirement of being a gentleman. As long as he is an ignorant country boy, he has no hope of social advancement. Pip understands this fact as a child, when he learns to read at Mr. Wopsle’s aunt’s school, and as a young man, when he takes lessons from Matthew Pocket. Ultimately, through the examples of Joe, Biddy, and Magwitch, Pip learns that social and educational improvement are irrelevant to one’s real worth and that conscience and affection are to be valued above erudition and social standing.

Throughout Great Expectations, Dickens explores the class system of Victorian England, ranging from the most wretched criminals (Magwitch) to the poor peasants of the marsh country (Joe and Biddy) to the middle class (Pumblechook) to the very rich (Miss Havisham). The theme of social class is central to the novel’s plot and to the ultimate moral theme of the book—Pip’s realization that wealth and class are less important than affection, loyalty, and inner worth. Pip achieves this realization when he is finally able to understand that, despite the esteem in which he holds Estella, one’s social status is in no way connected to one’s real character. Drummle, for instance, is an upper-class lout, while Magwitch, a persecuted convict, has a deep inner worth.

Perhaps the most important thing to remember about the novel’s treatment of social class is that the class system it portrays is based on the post-Industrial Revolution model of Victorian England. Dickens generally ignores the nobility and the hereditary aristocracy in favor of characters whose fortunes have been earned through commerce. Even Miss Havisham’s family fortune was made through the brewery that is still connected to her manor. In this way, by connecting the theme of social class to the idea of work and self-advancement, Dickens subtly reinforces the novel’s overarching theme of ambition and self-improvement.

The theme of crime, guilt, and innocence is explored throughout the novel largely through the characters of the convicts and the criminal lawyer Jaggers. From the handcuffs Joe mends at the smithy to the gallows at the prison in London, the imagery of crime and criminal justice pervades the book, becoming an important symbol of Pip’s inner struggle to reconcile his own inner moral conscience with the institutional justice system. In general, just as social class becomes a superficial standard of value that Pip must learn to look beyond in finding a better way to live his life, the external trappings of the criminal justice system (police, courts, jails, etc.) become a superficial standard of morality that Pip must learn to look beyond to trust his inner conscience. Magwitch, for instance, frightens Pip at first simply because he is a convict, and Pip feels guilty for helping him because he is afraid of the police. By the end of the book, however, Pip has discovered Magwitch’s inner nobility, and is able to disregard his external status as a criminal. Prompted by his conscience, he helps Magwitch to evade the law and the police. As Pip has learned to trust his conscience and to value Magwitch’s inner character, he has replaced an external standard of value with an internal one.

One of the most remarkable aspects of Dickens’s work is its structural intricacy and remarkable balance. Dickens’s plots involve complicated coincidences, extraordinarily tangled webs of human relationships, and highly dramatic developments in which setting, atmosphere, event, and character are all seamlessly fused.

In Great Expectations, perhaps the most visible sign of Dickens’s commitment to intricate dramatic symmetry—apart from the knot of character relationships, of course—is the fascinating motif of doubles that runs throughout the book. From the earliest scenes of the novel to the last, nearly every element of Great Expectations is mirrored or doubled at some other point in the book. There are two convicts on the marsh (Magwitch and Compeyson), two invalids (Mrs. Joe and Miss Havisham), two young women who interest Pip (Biddy and Estella), and so on. There are two secret benefactors: Magwitch, who gives Pip his fortune, and Pip, who mirrors Magwitch’s action by secretly buying Herbert’s way into the mercantile business. Finally, there are two adults who seek to mold children after their own purposes: Magwitch, who wishes to “own” a gentleman and decides to make Pip one, and Miss Havisham, who raises Estella to break men’s hearts in revenge for her own broken heart. Interestingly, both of these actions are motivated by Compeyson: Magwitch resents but is nonetheless covetous of Compeyson’s social status and education, which motivates his desire to make Pip a gentleman, and Miss Havisham’s heart was broken when Compeyson left her at the altar, which motivates her desire to achieve revenge through Estella. The relationship between Miss Havisham and Compeyson—a well-born woman and a common man—further mirrors the relationship between Estella and Pip.

This doubling of elements has no real bearing on the novel’s main themes, but, like the connection of weather and action, it adds to the sense that everything in Pip’s world is connected. Throughout Dickens’s works, this kind of dramatic symmetry is simply part of the fabric of his novelistic universe.

Throughout Great Expectations, the narrator uses images of inanimate objects to describe the physical appearance of characters—particularly minor characters, or characters with whom the narrator is not intimate. For example, Mrs. Joe looks as if she scrubs her face with a nutmeg grater, while the inscrutable features of Mr. Wemmick are repeatedly compared to a letter-box. This motif, which Dickens uses throughout his novels, may suggest a failure of empathy on the narrator’s part, or it may suggest that the character’s position in life is pressuring them to resemble a thing more than a human being. The latter interpretation would mean that the motif in general is part of a social critique, in that it implies that an institution such as the class system or the criminal justice system dehumanizes certain people.

In Satis House, Dickens creates a magnificent Gothic setting whose various elements symbolize Pip’s romantic perception of the upper class and many other themes of the book. On her decaying body, Miss Havisham’s wedding dress becomes an ironic symbol of death and degeneration. The wedding dress and the wedding feast symbolize Miss Havisham’s past, and the stopped clocks throughout the house symbolize her determined attempt to freeze time by refusing to change anything from the way it was when she was jilted on her wedding day. The brewery next to the house symbolizes the connection between commerce and wealth: Miss Havisham’s fortune is not the product of an aristocratic birth but of a recent success in industrial capitalism. Finally, the crumbling, dilapidated stones of the house, as well as the darkness and dust that pervade it, symbolize the general decadence of the lives of its inhabitants and of the upper class as a whole.

The setting almost always symbolizes a theme in Great Expectations and always sets a tone that is perfectly matched to the novel’s dramatic action. The misty marshes near Pip’s childhood home in Kent, one of the most evocative of the book’s settings, are used several times to symbolize danger and uncertainty. As a child, Pip brings Magwitch a file and food in these mists; later, he is kidnapped by Orlick and nearly murdered in them. Whenever Pip goes into the mists, something dangerous is likely to happen. Significantly, Pip must go through the mists when he travels to London shortly after receiving his fortune, alerting the reader that this apparently positive development in his life may have dangerous consequences.

Although he is a minor character in the novel, Bentley Drummle provides an important contrast with Pip and represents the arbitrary nature of class distinctions. In his mind, Pip has connected the ideas of moral, social, and educational advancement so that each depends on the others. The coarse and cruel Drummle, a member of the upper class, provides Pip with proof that social advancement has no inherent connection to intelligence or moral worth. Drummle is a lout who has inherited immense wealth, while Pip’s friend and brother-in-law Joe is a good man who works hard for the little he earns. Drummle’s negative example helps Pip to see the inner worth of characters such as Magwitch and Joe, and eventually to discard his immature fantasies about wealth and class in favor of a new understanding that is both more compassionate and more realistic.
