Pip's fever and recovery can be seen as symbolic death and rebirth. Explain how Pip is reborn at the end of the novel. What parts of Pip have died?

After recovering from his fever, Pip is a man reborn. He's rediscovered himself, finally realizing who and what he really is. In pursuing the life of a man about town, a gentleman of means, he'd forgotten where he came from. He'd become ashamed of his humble origins as a "common laboring boy," an apprentice blacksmith living on the bleak Romney Marshes. Over time, he'd developed into a snob, embarrassed to be reminded of his past upon Joe Gargery's showing up to his apartment one day. But when Pip wakes up and sees Joe's kindly face, he feels utterly ashamed of how he's treated his very dearest friend.
There is nothing wrong in Pip wanting to live the life of a gentleman—to have money, nice clothes, and a decent place to live. Unfortunately, he loses sight of what's truly important in life: friendship, love, and true companionship. In Pip's rebirth, all that social snobbery, obsession with changing fashions and love of luxury have died. But then it could be argued that they were never really a part of his soul to begin with. Reborn, he's not really a new man at all, just the old Pip.
