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.
