Here’s a solid example of emotional insight from Jane Austen.
After playing some Italian songs, Miss Bingley varied the charm by a lively Scotch air; and soon afterwards Mr. Darcy, drawing near Elizabeth, said to her:
“Do not you feel a great inclination, Miss Bennet, to seize such an opportunity of dancing a reel?”
She smiled, but made no answer. He repeated the question, with some surprise at her silence.
“Oh!” said she, “I heard you before, but I could not immediately determine what to say in reply. You wanted me, I know, to say ‘Yes,’ that you might have the pleasure of despising my taste; but I always delight in overthrowing those kind of schemes, and cheating a person of their premeditated contempt. I have, therefore, made up my mind to tell you, that I do not want to dance a reel at all—and now despise me if you dare.”
“Indeed I do not dare.”
Elizabeth, having rather expected to affront him, was amazed at his gallantry; but there was a mixture of sweetness and archness in her manner which made it difficult for her to affront anybody; and Darcy had never been so bewitched by any woman as he was by her. He really believed, that were it not for the inferiority of her connections, he should be in some danger.
This conveys emotional insight all the way through, of course. Perhaps the easiest example to get with from this passage is, “Indeed I do not dare.” You can feel Darcy’s admiration for Elizabeth, his respect for her. You get a sense of his emotion about her and what that emotion means. Read it again – do you feel it?
