the 2 Catherines : mother & daughter the 2 major characters: closely matched, see
themselves as identical Catherine herself: divided into 2 warring
sides: the side that wants Edgar & the side that wants Heathcliff
Just as the novel begins and ends with a Catherine Earnshaw, the name of Hareton Earnshaw also bookends as era; the final master of Wuthering Heights shares his name with a distant ancestor, whose name was inscribed above the main door in 1500.
“I have not broken your heart—you have broken it; and in breaking it, you have broken mine. So much the worse for me, that I am strong. Do I want to live? What kind of living will it be when you—oh, God! Would you like to live with your soul in the grave?”
“It would degrade me to marry Heathcliff now; so he shall never know how I love him; and that, not because he is handsome, Nelly, but because he’s more myself than I am. Whatever our souls are made of, his and mine are the same, and [Edgar’s] is as different as a moonbeam from lightning, or frost from fire.”
