Found an interesting article on Lifehacker this morning: What Books Have Changed Your Life?
"Technologist and well-read fellow Kevin Kelly lists the books that have changed his life. Life-changing books are not just your favorite books, he explains, but 'books that altered your behavior, changed your mind, redirected the course of your life. Books as levers.'"
While I have a lot of favorite books, here are the ones that have changed my life in some way: changed my beliefs, altered my behavior, or just broadened my worldview in profound ways, in no particular order.
Also on the list, but not available on Amazon, are:
THE NEW MAGUS by Donald Tyson (which introduced me to concepts of quantum physics before I knew what it was)
TIME TO STAND UP, a speech by Richard Dawkins (which was my "shock and awe" introduction to atheism)
