Some of these posts are not accepting of the fact that some of the story/style/characterisation is of its time, yes, but still great literature. eg Huckleberry Finn. Yes, it has racism in it. But that was how American was then - hugely racist, so it wouldn't make sense for it not to contain any. I'm a school librarian and I still have it on my shelves. Funnily enough no-one ever picks it up as it just doesn't have wide appeal to a teenage audience these days. If anyone has picked it up I have a conversation warn them about the racism and say it has historical relevance and they need to be strongly aware of that. I would strongly advise any student who wasn't astute or "worldly" or well-read, or anyone who has made racist comments in the past.
Similarly, with Jane Eyre, Mr Rochester seems very cold. But men WERE then. If you were wealthy you were supposed to marry into the right family, not for love. There wasn't any sexual equality. I don't think it's any great romance. It's just a story about a dutiful woman from a difficult background recognising SOME semblance of humanity and affection buried very deep in an uptight, staid gentleman of the time, and him recognising something good in HER qualities. I love it. There is no true happy ending. They end up with each other but not in a heading off in the sunset romantic way. It's just a quiet acceptance of how things are with each other.
I think with literature you can love a character for being well-written or interesting. You don't have to LIKE them. Think of Fagin and Bill Sykes. No-one wants an Oliver Twist without them, just because they were terribly cruel towards children and this is not something we want to hear in the modern age of child protection and welfare. Dickens was an important social commentator. Again, of historical importance, and it adds another strand to his literature when you read it now.
We can go back and re-read books from years ago through new eyes because we're a bit more enlightened now than when they were written. And that is an education in itself, recognising how society has changed so much that they would not be put into publication if written today.
We should all read widely because it helps to cultivate literary good taste and we can become discerning readers. I remember enjoying things like Diary of a Nobody and Three Men in a Boat around the time I was also reading Jane Green and other chicklit trash in my 20s, along with Ian McEwan and Dickens. All books have their place. The worst thing is to read nothing but the same genre.
I can fully understand English Lit graduates having read trashy stuff when they were younger!
