Gödel, Escher, Bach: An Eternal Golden Braid

Gödel, Escher, Bach: An Eternal Golden Braid - Douglas R. Hofstadter Full disclosure: I'm only about 1/4 way through this book. Every few months, I read about 25 pages, and that's about all I can take before I need a break. Some of it is way above my head. Much of it is easily understandable. The author is clearly trying to make this material accessable to a general audience. I'm not sure if this is helpful to put in a book review, but my personal experience is that I need a long time to "digest" this sort of material. In a nutshell, the book explores the idea of recursive or self-referential themes, as expressed in three media: music (through the works of J.S. Bach); art (through the works of Dutch draftsman M.C. Escher); and mathematics (through the theorems of K. Goedel). To his credit, author Douglas Hofstader includes generous visual aids to augment the text, and his Socratic dialogues between Achilles and the tortise are fun.
