I think many readers will be surprised at how accessible "Gödel, Escher, Bach" actually is. I'm not an expert at anything: I have no work experience and maybe two serious computer science courses under my belt, but GEB really satisfies an intellectual curiosity I've had for years. I'm 550 pages in (out of about 750 pages) and with the exception of the two chapters discussing the anatomy of the human brain (a subject I'm just not that interested in), I've torn through this book—I only started reading about three months ago, which means I've been reading GEB much faster than any other book I've ever opened. I highly recommend "Gödel, Escher, Bach" even to those who have seen other people recommend it yet have been reluctant to try it out.
