By looking at the brilliant minds of mathematician Kurt Godel, graphic artist M. C. Escher, and composer Johann Sebastian Bach, computer-science and cognitive-science professor Douglas Hofstadter (http://en.wikipedia.org/wiki/Douglas_hofstadter) ties together the aesthetic gift of pattern recognition and manipulation with theories on artificial intelligence, human intelligence, and the essence of self-awareness. Godel, Escher, Bach (1979) is not a simple read. The ideas are complex and the logic subtle. But it is a completely satisfying book, and reading it is one of those rare experiences when you somehow sense that you are smarter than when you started.
