If you hang around smart people enough, it becomes clear that it's dumb to lie about which books you've read.
There are millions of books out there and you can be a smart person whilst not having read a page of Tolstoy or Kafka. I'd recommend both authors; but, you can be a deeply intelligent and thoughtful person without having read them.
I've read both of them; but, I haven't read a single book by Charlotte Brontë. I've read Emma Goldman thoroughly; but, I've only read a few short stories by Nathaniel Hawthorne.
I could fill the Galaxy with what I haven't read.
So could you.
It's nothing to be ashamed about.
