Feeling…clamoured wildly. “Oh comply!” it said, “Think of his misery, think of his danger – look at his state when left alone…soothe him; save him; love him; tell him you love him and will be his. Who in the world cares for you? or who will be injured by what you do?”
Still indomitable was the reply – “I care for myself. The more solitary, the more friendless, the more unsustained I am, the more I will respect myself. I will keep the law given by God, sanctioned by man. I will hold to the principles received by me when I was sane, and not mad – as I am now. Laws and principles are not for the times when there is no temptation: they are for such moments as this, when body and soul rise in mutiny against their rigour, stringent are they; inviolate they shall be…They have a worth – so I have always believed; and if I cannot believe it now, it is because I am insane – quite insane: with my veins running fire, and my heart beating faster than I can count its throbs. Preconceived opinions, foregone determinations, are all I have at this hour to stand by: there I plant my foot!”

– Charlotte Bronte

Jane Eyre, Chapter 27. Jane is almost persuaded to give in to love and desire and remain with Rochester. Her mind and heart are in turmoil and conflict over the battle between what is right and wrong. Rochester, who is legally married to Bertha Mason, wants her to stay. Jane feels tested, admitting that her veins are metaphorically “running fire” with passion for Rochester. She also longs for a real family and sense of belonging – “Who in the world cares for you?” she asks herself. But she believes strongly that she would lose her self-respect if she were to agree to be Rochester’s mistress. In the end Jane’s moral principles win the internal debate that is raging in her head. She decides to abide by God’s law and leave Thornfield, even if that means being “solitary,” “friendless” and “unsustained.”
