I am sure, sir, I should never mistake informality for insolence: one I rather like, the other nothing free-born would submit to, even for a salary.
Chapter 14 · Jane Eyre
Context
Rochester has asked Jane to accept informality without mistaking it for rudeness. Jane agrees, but adds a condition: she draws a firm line at insolence, which no free person should tolerate.
Analysis
The antithesis "one I rather like, the other nothing free-born would submit to" hinges on the word "free-born," which carries both literal and symbolic weight. Jane isn't literally enslaved, but by invoking that term she equates tolerating insolence with bondage—a rhetorical escalation that reframes the governess's position as a question of fundamental human dignity, not just employment terms.
Essay Tip
Support a thesis that Jane uses the language of enslavement and freedom to argue that economic dependence should not strip away moral rights—this quote shows her refusing to let her salary define the limits of her self-respect, a stance that prefigures her later refusal to be Rochester's mistress.
