Henry James said this quote

You will think you take generous views of her; but you will never begin to know through what a strange sea of feeling she passed before she accepted you. As she stood there in front of you the other day, she plunged into it. She said 'Why not?' to something which, a few hours earlier, had been inconceivable. She turned about on a thousand gathered prejudices and traditions as on a pivot, and looked where she had never looked hitherto.
