You talk of her mind being unsettled - how the devil could it be otherwise, in her frightful isolation? And that insipid, paltry creature attending her from duty and humanity! From pity and charity. He might as well plant an oak in a flower-pot, and expect it to thrive, as imagine he can restore her to vigour in the soil of his shallow cares!

Heathcliff (Ch. XIV). - Wuthering Heights (1847)
