All of these enable him to approach Godel's theorem from different directions again and again without boring the reader - in fact being much more interesting than an ordinary explanation. The author has woven many things he loves into this book, including lighthearted fiction and music and art.

This is introduced early in the book, the explanation (as technical as any non professional mathematician is likely to want) is at the heart of it, and analogies and ramifications are approached from different angles to the very end. Most obviously, it is a book about Godel's theorem. This is an amazing book by Douglas Hofstadter. The expositions are much harder, but they treat some stuff that is very fundamental to computer science, so at least computer science students should consider it a must read. The dialogues are very witty and a joy to read. The book has expositions and dialogues, in turn. This leads to paradoxes Epimenides already knew that, and for mathematical logic, groundbreaking work in this area was done by Kurt GГ¶del. He also dwells on languages powerful enough to express their own meaning. Hofstadter tries very hard to convince us that meaning can be an emergent property: that it should not surprise us that the man in Searle's Chinese room doesn't speak Chinese, while the system as a whole can. For instance, assembly language can be used to implement higher level programming languages patterns of neuron signals can be said to express a higher-level language of brain signals the same can be said for patterns of ant movement. What is more, they can be used to form a higher level language, with a meaning on a different level. Mathematical logic, computer programming languages, but also the system of neuron signalling in the brain, or the patterns of ants moving inside and around an ant hill, all are designed to form complex combinations that express something meaningful. Language is a system of forms arranged to express meaning. This book sparkles with ideas it all revolves around the concepts of recursion and language.
