At The Common Room, a wonderful quote by Tony Tanner from an introduction to Jane Austin's Mansfield Park (edition not specified):
In her stillness she is not inactive: on the contrary, she is often holding on strenuously to standards and values which others all around her are thoughtlessly abandoning.
The she referred to is Fanny, the ... well, she is not exactly the protagonist. I've always imagined Fanny as the story teller; she doesn't make many decisions (only one important one) nor take direct action in most of the book. She reflects the actions of the other characters.
