I am sure you are familiar with the "Mad Woman in the Attic" argument for Jane Eyre to be a feminist novel. It is, in my view, but then, of course, it depends on how you define feminism (now and back then). But the mirror image of the "mad woman" is astounding, if you read it not only as a gothic element, but as a dark template the author deliberately inserted into the novel to show all that has to be hidden in the "attic" for Jane Eyre to be a "good woman". Also: male impotence (blindness!) as a prerequisite for a happy ending always seems like a feminist play to me. ;)
