A fantastic book full of passion which explains in non-technical terms some very non-trivial ideas on the many-worlds interpretation of quantum physics and shows how many other highly non-trivial things (from the concept of time to evolution) depend on it. I really, really like Deutsch's take-no-prisoner attitude and his willingness to pursue in earnest the many highly counter-intuitive consequences of what he believes to be the true explanation of reality.

challenging to say the least - in testing one's understanding and in readiness to take conclusions all the way. And mean it! very informative and lots of usefull stuff

Review by

This is one of the most interesting and thought-provoking science books that I've read for a long, long time.Deutsch attempts to draw together four strands: quantum physics, knowledge theory, computation and evolution into an over-arching 'Theory of Everything'. This theory is much broader than the narrow 'unify-the-four-forces' theory which physicists have been striving to formulate for many years.The most compelling feature of this book is the way that accepting the reality of the multiverse (parellel universes), as implied by quanutm physics, can explain at a stroke such thorny problems such as the nonsense that is Schrödinger's cat, free will in a deterministic universe, what makes life special (and how to define it). Even the apparently insoluble 'grandfather paradox' of time travel is shown not to exist if time travel takes place in a universe which bifurcates at every 'choice'.Deutsch has an uncanny way of anticipating his reader's thoughts. On a number of occasions objections or questions which arose in my mind were immediately addressed by him a little further on in the text. Somewhat alarmingly, halfway through reading this book, I was in a 'heads or tails' competition wth 100 other people. Before the throw of the first coin I joked that somewhere there was a universe in which I would win the competion. 8 throws of the coin later I was astounded to find that I am in that universe, as are you!Why did I not give it 5 stars then? I have to say that the chapter covering an argument with a crypto-inductivist (a word I now drop into conversation at every opportunity) lost me and I also found the chapter on the foundations of maths hard work (I should have skipped it, as the author advised!).Highly recommended if you have even a passing interest in any of the topics mentioned.
