The Hitchhiker's Guide series

Island of the blue dolphins by ODell got my reading bug started when I was a kid.
But the rest I will have to think about there are so many. BTW the poisonwood bible was a great read.

My 1971 diary, my 1972 diary, my 1973 diary, my 1974 diary, my 1975 diary. I stopped writing them and keeping them to read later because they were found by my GF. Too much information she used to become my wife in 1980.

The Crying of Lot 49 - Pynchon
Pic - Kerouac
Master and Margarita - Bulgakov
Moby Dick - Melville
Genesis - Who knows? [earliest book to have as main characters grifters, prisoners, murderers, goatherds, alcoholics, and a whore.]

6. The Brain Diet by Dr. Alan C. Logan

7. How To Analyze People On Sight by Elsie Lincoln Benedict

8. Physiognomy by Dr. Joseph Simms

9. Common Sense by Thomas Paine

10. Opticks by Isaac Newton

11. USA Culture Smart! by some fat hoe

12. A Discourse on Method by Renee Descartes

13. Watchmen by Alan Moore

14. Philosophae Naturalis Principia Mathematica by Isaac Newton

15. Some paper on Grothendieck Rings

Most of what I would offer are books that, if anyone has the slightest interest, would have read them already: The Hitchhikers Guide series, 1984, The Lord of the Rings trilogy, the Bible in general for empowering me to call bullshit as a bible scholar

The one recommendation I have that you might not have already read is the Soul of the Night by Chet Raymo. Beautiful poetic language about astrophysics, the stars, the myths man has made around everything. He’s a physics professor at stone hill and writes beautifully. It was fairly heavy reading material for a 14 year old but I think it was one of the first things to really shake me out of my mystic religious haze and wake me up to the beauty of the natural universe.

Okay, I have to ask, how long did it take you to read The Brothers Karamazov?!? I've heard it's a great book. You've also now have me curious about the Book of Ruth. ..

Copied and pasted from a previous post of mine:
I just finished Sapiens by Yuval Noah Harari. Loved it. Lots of little interesting facts. Also listened to Letter To A Christian Nation by Sam Harris. Short, but also good. Also recently finish God is Not Great by Christopher Hitchens. Very good but brutally honest when speaking about the atrocities committed by the church. Currently listening to The God Delusion by Richard Dawkins. Very blunt and unapologetic about his disdain for all religions.

Edit: Okay. I know it's a kids book but I don't care! The Giver by Lois Lowry. I can't get the images and scenes out of my head that I created by reading it. Watched the movie and was devastated. My brain was much more interesting!

Genesis - Who knows? [earliest book to have as main characters grifters, prisoners, murderers, goatherds, alcoholics, and a whore.]

Putting on the Mind of Christ by Jim Marion - because it was my springboard out of typical Christian thought.

The Alchemist by Paulo Coehlo - because it gets at the idea that there is something out there, without having to define it.

Adventures Beyond the Body by William Buhlman - because during the time I was reading it I had my first out of body experience, and it provided great food for thought

The Baghavad Gita - The character of Krishna, I thought, provided a nice framework within which to ponder our human situation

Siddhartha by Herman Hesse - A nice example of following one's own thoughts rather than adhering to an "off the shelf" belief system.

.... and various books on Jungian psychology - again, his ideas provide a good framework within which to understand our lives and our selves.

I know this isn't exactly what you are looking for, but I read a book when I was young that totally changed the way I think/approach others. I can't remember the title, but it was by Robert Heinlein. In the story a dragon from Venus (yes, I know this sounds silly, but it works in the story) tells a human that his people are totally astounded that humans can stand on a sidewalk and just by looking gauge the speeds of the oncoming cars to decide if it is save to cross the street. I had never thought about it but it really is a remarkable skill. The book made me realize that how I think of things is not necessarily the way another does. I've been reading science fiction since then. My advice is to check out the various types of science fiction and try something that sounds good to you.
