I first read GEB when I was a teenager (and I&#x27;ve re-read it many many times since).  It is one of the few books that made me re-think the way that I think, and it&#x27;s one of my favorite books of all time.  &quot;The Emperor&#x27;s New Mind&quot; didn&#x27;t thrill me the way GEB did, but I enjoyed it.  I recently read &quot;I Am A Strange Loop&quot; and it got me thinking again :)
