"Nelly, I am Heathcliff! He's always, always in my mind: not as a pleasure, any more than I am always a pleasure to myself, but as my own being."

- Emily Bronte, Wuthering Heights, Ch. 9

"'I seek no revenge on you,' replied Heathcliff, less vehemently. 'That's not the plan. The tyrant grinds down his slaves and they don't turn against him; they crush those beneath them. You are welcome to torture me to death for your amusement, only allow me to amuse myself a little in the same style, and refrain from insult as much as you are able. Having levelled my palace, don't erect a hovel and complacently admire your own charity in giving me that for a home. If I imagined you really wished me to marry Isabel, I'd cut my throat!'"

- Emily Bronte, Wuthering Heights, Ch. 11
