How we cite our quotes:
A mind like hers, once opening to suspicion, made rapid progress. She touched—she admitted— she acknowledged the whole truth. (47.25)
For once, Emma’s wit aids in her ability to grasp the reality of a situation. Austen captures the utter confusion of her character’s thoughts during a moment of revelation.
To understand, thoroughly understand her own heart, was the first endeavour. (47.37)
Emma’s self-reflection is only prompted when her emotions are directly engaged. Austen seems to suggest, for Emma at least, that rational needs to be accompanied by emotional engagement.
With insufferable vanity had she believed herself in the secret of every body's feelings; with unpardonable arrogance proposed to arrange every body's destiny. She was proved to have been universally mistaken; and she had not quite done nothing—for she had done mischief. (47.40)
Emma’s self-recrimination, while mostly true, is also incredibly melodramatic – a sign, perhaps, that she hasn’t truly learned how to judge her actions.
