Does Pip develop or change throughout the novel?

Pip learns the difficult lesson of humility in the course
of the novel. He also develops his understanding of the difference between character and
class.  Miss Havisham's cruel machinations; forcing Pip to learn first his own, then
Estella's ambivalent social position show Dickens bringing his characters up to date
with a changing age where class and social position are no longer exclusive or
fixed.

 Miss Havisham's patronage (a deception in
itself) teaches Pip that the quality which Estella condemned in him; his 'coarseness',
which he, in turn, condemned in himself and in his beloved Joe, is simply honesty. What
the characters of the young Pip, Joe, Biddy and Magwitch represent are 'coarseness' in
the form of unvarnished truth. They are fair, honest and full of integrity. Those who
initially turn Pip's head - Miss Havisham and Estella - represent instability deception,
arrogance and superficiality.
