Feeling . . . clamoured wildly. “Oh, comply!” it said. “. . . 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 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.”

In this quotation, near the end of Chapter 27, Jane asserts her strong sense of moral integrity over and against her intense immediate feelings. Rochester has been trying to convince her to stay with him despite the fact that he is still legally married to Bertha Mason. His argument almost persuades Jane: Rochester is the first person who has ever truly loved her. Yet she knows that staying with him would mean compromising herself, because she would be Rochester’s mistress rather than his wife. Not only would she lose her self-respect, she would probably lose Rochester’s, too, in the end. Thus Jane asserts her worth and her ability to love herself regardless of how others treat her.

The passage also sheds light upon Jane’s understanding of religion. She sees God as the giver of the laws by which she must live. When she can no longer trust herself to exercise good judgment, she looks to these principles as an objective point of reference.

Jane’s allusions to her “madness” and “insanity” bring out an interesting parallel between Jane and Bertha Mason. It is possible to see Bertha as a double for Jane, who embodies what Jane feels within—especially since the externalization of interior sentiment is a trait common to the Gothic novel.

The description of Jane’s blood running like “fire” constitutes one of many points in the book in which Jane is associated with flames.
