How we cite our quotes:
"As I giv' you to understand just now, I'm famous for it. It was the money left me, and the gains of the first few year wot I sent home to Mr. Jaggers—all for you—when he first come arter you, agreeable to my letter." (2.39.77)
Magwitch is perhaps the only person in the novel who is generous with his money. His relationship to money is closely related to his dream of making Pip a gentleman.
'He was a convict, a few year ago, and is a ignorant common fellow now, for all he's lucky,' what do I say? I says to myself, 'If I ain't a gentleman, nor yet ain't got no learning, I'm the owner of such. All on you owns stock and land; which on you owns a brought-up London gentleman?' (39.78)
Magwitch may seem like he's being generous with his money, but it's actually the exact opposite of generosity: he's using his money to "buy" himself a gentleman. Of course, by now, Pip knows that you can't buy gentlemanliness: it's maybe the one thing in the world that can't be bought.
