Books That Ask the Big Questions

Maybe it’s because my dad was a philosophy professor, but I’ve always had a huge soft spot for books that dared to ask the huge, unanswerable questions about life and existence. Like the Hitchhiker’s Guide to the Galaxy (pictured above!). When you sit down to write a book, it feels kind of arrogant, maybe even a little crazy, to think that you can have something to say about the Big Ideas of the nature of the universe and whatnot – but you don’t have to answer these questions, just shed some light on them. I feel like I will always love a book for having big ideas, even if it leaves me having to figure out a lot of stuff on my own afterward. Actually, I’ll especially love any book that leaves me trying to figure out stuff on my own after I’m done reading. What do you think? And what’s your favorite book that asks the big questions?
