What classic book should I read

By tender-badger

Could someone recommend a classic book for me? I haven’t really gotten into many classics yet—only read Emma and I honestly loved it—but I’d rather not do another Jane Austen. I’m mostly into big philosophical questions (like meaning of life and ethics/morality), psychology stuff (personality and mental health/psychiatric conditions), and also physics/cosmology. I also like history a lot, especially European, Asian, and Middle Eastern. If you have any suggestions, I’d really appreciate it—and if you can point out which of those interests the book fits, that would be great. Thanks!
