“‘I’ve no more business to marry Edgar Linton than I have to be in heaven; and if the wicked man in there had not brought Heathcliff so low, I shouldn’t have thought it. It would degrade me to marry Heathcliff now; so he shall never know how I love him; and that, not because he’s handsome, Nelly, but because he’s more myself than I am. Whatever our souls are made of, his and mine are the same, and Linton’s is as different as a moonbeam from lightning, or frost from fire.'”

—from Wuthering Heights by Emily Brontë
