Austen is sometimes recruited to discredit such tendencies. Yet how should a chastened moral philosophy proceed? Seeing Catherine otherwise than as a faux gothic heroine reveals the promise in a neglected direction: scrutinize practices that support our unstudied inclinations to take as natural particular ways of applying concepts.
