this is a very, very good list. read most of these books in high school. Destoievski is still one of my favourite authors, and i still have dreams of Eco's 1300s abbey.
i would also mention Kafka, and any of the SciFi greats (Asimov, Clarke, P.K. Dick etc). Re-read a lot of these this past year.
and i would also mention Marcus Aurelius "Meditations", a book written 2000 years ago by one of the greatest thinkers of his time.
there are so many good book written throughout history it's absolutely crazy. the only problem i see is the monumental amount of crappy books that have been launching recently and becoming instant hits. combined with a "does this take longer than a 10 minute youtube video" attitude.
otherwise, if you have a modicum amount of patience, any of those books will prove to be an unforgettable experience.
