Conventionality is not morality. Self-righteousness is not religion. To attack the first is not to assail the last.

Brontë distinguishes outward social conformity (“conventionality”) from genuine ethical conduct (“morality”), and pious posturing (“self-righteousness”) from authentic faith (“religion”). The final sentence clarifies a frequent misunderstanding: criticizing empty social or religious forms is not the same as attacking true virtue or true belief. The thought reflects a central Brontëan concern—how institutions and respectable appearances can mask cruelty, hypocrisy, or spiritual pride, while real goodness may appear unconventional. It also defends moral independence: one can reject oppressive norms and sanctimonious judgment without rejecting morality or religion themselves.
