"Cognition emerges from hidden neurological mechanisms" being the author's summaries of not only GEB (1979) but also Dawkin's The Selfish Gene (1976), I am fully ready to argue that GEB was an intellectual's retreat from Reagan. American culture was big on trite wordplay back then. It was largely insufferable.GEB waxes poetics about recursion for pretty much its entire body, comparing recursive changes of a structure to fugue and drawing parallels. I have no doubt that, just as SICP, it was mind-blowing at its time. But today? I learned about this shit in high school CS and middle school music classes, respectively. Putting it together is perhaps non-trivial, sure, but with the benefit of GEB doing a lot of the work, people who came after can do it all in a matter of 3 hour lecture.
