What is the theme present in the story "Great Expectations"? How does it pertains to the story?

There is more than one theme present in Great Expectations. However, one of the main themes is Self-Improvement. This theme is seen in multiple ways throughout the text. This theme is extremely evident in the character Pip, who is very hard on himself. First he wants to improve himself morally.

Second, he wants to improve himself socially. In love with Estella, a member of a higher social class, he longs to be a part of this class. His ultimate desire is to be considered "a gentement."

Lastly, he wishes to improve himself educationally. In order to be considered "a gentlemen" in the higher social class, he must improve his education. A true gentlemen fulfills all his academic requirements. This is way out of reach for Pip and he knows this.

Of course Pip learns in the end that all of these self-improvements are not necessary to determine onces true worth.
