Hey there,
My analysis is probably similar to Jamon's but here's my input:
1. “I had not intended to love him: the reader knows I had wrought hard to extirpate from my soul the germs of love there detected; and now, at the first renewed view of him, they spontaneously revived green and strong! He made me love him without looking at me!”
Metaphor with 'germs of love': Maybe you could talk about the unexpected nature of love, and possibly discuss the implications of (I'm assuming) Jane falling in love with Mr Rochester- possibly foreshadowing Jane's discovery of how Mr Rochester is still married and her disgust when she finds out his wife is still alive, yet locked in a room?
2. “I doubted I had taken a step which sank instead of raising me in the scale of social existence.”
Sibilance, emphasising on the importance of social status in a Victorian society, or even on the role of women, since Jane is an orphan and a governess.
3. “Glorious discovery to a lonely wretch! This was wealth indeed!”
Exclamation, emphasising the importance of wealth in Victorian society (i.e. emphasis on dowry when a couple is to be married)- even though she kinda sounds like a gold digger, it was important to make sure that whoever you're gonna marry has money to secure a position in society.
4. “Women are supposed to be very calm generally: but women feel just as men feel; …. they suffer from too rigid a restraint, to absolute a stagnation, precisely as men would suffer;
Anaphora since it repeats 'just as men feel' to emphasise on the role of women in Victorian society- men have to reach that expectation of being rich and having a position in society (either landowner, clergyman or part of military) whereas women's mannerism were what made them a desirable wife.
5. “Ye are formed for labour, not for love. A missionary’s wife you must – shall be. You shall be mine: I claim you – not for my pleasure, but for my sovereign’s service.”
High modality: In a society where arranged marriage was common, the high modality emphasises how women don't really have a say on who they wanna marry. St John wants her to marry him but Jane wants to marry for love, going against society's expectations on marriage. This also becomes a turning point for Jane to look for Mr Rochester again, showing that she is headstrong and has strong values, again, something women aren't expected to have in Victorian society.
Hopefully my analysis was helpful (you've certainly rekindled my love for Mr Rochester lol).
I also found another great resource just in case you need some ideas on what other quotes you can use.
Again, hope this helps!
