Gödel, Escher, Bach: An Eternal Golden Braid – Douglas R Hofstadter

Description

A metaphorical fugue on minds and machines in the spirit of Lewis Carroll

“Every few decades an unknown author brings out a book of such depth, charity, range, wit, beauty, and originality that it is recognized at once as a major literary event. This is such a work.” —Scientific American

GEB is a unique insight into the nature of “I,” self, soul, and consciousness, centered on a notion that its youthful author dubbed “strange loop,” inspired by the twisty self-referential construction invented by logician Kurt Gödel, whereby a sentence asserts its own unprovability. The book’s chapters alternate with Bach-like contrapuntal dialogues between whimsical characters (especially Achilles and the Tortoise), and each dialogue’s intricate structure exemplifies the notion being discussed in it, thus creating indirect self-reference (a fact unsuspected by the characters). The book, filled with analogies, wordplay, humor, and mind-twisting prints by M. C. Escher, has inspired generations of bright students to study cognitive science and the philosophy of mind.

Douglas Hofstadter’s book is concerned directly with the nature of “maps” or links between formal systems. However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.
