A bold and all-embracing exploration of the nature and progress of knowledge from one of today's great thinkers. Throughout history, mankind has struggled to understand life's mysteries, from the mundane to the seemingly miraculous. In this important new book, David Deutsch, an award-winning pioneer in the field of quantum computation, argues that explanations have a fundamental place in the universe. They have unlimited scope and power to cause change, and the quest to improve them is the basic regulating principle not only of science but of all successful human endeavor. This stream of ever improving explanations has infinite reach, according to Deutsch: we are subject only to the laws of physics, and they impose no upper boundary to what we can eventually understand, control, and achieve. In his previous book, The Fabric of Reality, Deutsch describe the four deepest strands of existing knowledge-the theories of evolution, quantum physics, knowledge, and computation-arguing jointly they reveal a unified fabric of reality. In this new book, he applies that worldview to a wide range of issues and unsolved problems, from creativity and free will to the origin and future of the human species. Filled with startling new conclusions about human choice, optimism, scientific explanation, and the evolution of culture, The Beginning of Infinity is a groundbreaking audio book that will become a classic of its kind.

Review

"A brilliant and exhilarating and profoundly eccentric book. It's about everything: art, science, philosophy, history, politics, evil, death, the future, infinity, bugs, thumbs, what have you...It hardly seems worth saying...that the chutzpah of this guy is almost beyond belief, and that any book with these sorts of ambitions is necessarily, in some overall sense, a failure, or a fraud, or a joke, or madness. But Deutsch...is so smart, and so strange, and so creative, and so inexhaustibly curious, and so vividly intellectually alive, that it is a distinct privilege, notwithstanding everything, to spend time in his head."

-- "New York Times Book Review"

"Among the most ambitious works of nonfiction I have read."

-- "New Yorker"

"An adventurous, intellectually stimulating book on how problems are solved."

-- "Barnes & Noble, editorial review"

"Both skeptical and optimistic, Deutsch devotes ingenious chapters to refuting ideas (empiricism, induction, holism) and philosophies (positivism, most modernism, post-modernism) that limit what we can learn...[a] provocative, imaginative investigation of human genius."

-- "Kirkus Reviews (starred review)"

"Makes the case for infinite progress with such passion, imagination, and quirky brilliance."

-- "Wall Street Journal"

How can we tell what are good explanations and what are bad ones?
David Deutsch's excellent (2011) book: The Beginning of Infinity has been a major influence on my recent work in the field of dysology. Deutsch's clear writing helped me to see more clearly how the philosophy of science allows us to know what makes an explanation good or bad. I used his book as a framework to criticise the current notion of so called 'crime science' that is being propagated within the Jill Dando Institute for Security and Crime Science at the University College London. Deutsch's explanation of Karl Popper's philosophy made clear for me several things that I already knew before reading it. What Deutsch did was to enable me to understand those ideas better, and to appreciate the magnitude of their importance in helping us tell good explanations from bad. Deutsch is an expert universal explainer of existing knowledge and adds to what we know with more than a few new and important explanations of his own. For example, he has reversed my opinion regarding the hypothesis (that has become orthodoxy) that underpins Jared Diamond's award winning book Guns Germs and Steel. If you are seriously interested in knowing what makes a good or bad explanation for anything then I suggest you buy Deutsch's book today. I bought mine from Amazon and saved money since it is retailing at my local book shop in Nottingham England for £25. So far so good then because in many areas Deutsch meets the test set by the great mathematician David Hilbert who said at the second International Congress of Mathematicians in Paris in the summer of 1900: "An old French mathematician said: `A mathematical theory is not to be considered complete until you have made it so clear that you can explain it to the first man whom you meet on the street.' This clearness and ease of comprehension, here insisted on for a mathematical theory, I should still more demand for a mathematical problem if it is to be perfect; for what is clear and easily comprehended attracts, the complicated repels us." (David Hilbert 1900). Deutsch's Dog's Dilemma Personally, I struggled with the explanation of infinity in this book regarding a thought experiment in a hotel with an infinite number of rooms. In the explanation a dog that is moved from room to room ceases - at some point - to exist. The dog is (or becomes) nowhere. That explanation was lost on me and seems to contradict later quantum mechanics arguments in the book that I understand are claiming that things will always exist once they have existed. But then I'm no quantum physicist. I'd like to know more about that dog and why it is no more and nowhere, just in case I end up interfering with photons and atoms in the multiverse to influence a distant - or very close - world where just such a hotel exists and where I am a dog being passed from room to room. Should I bite someone in the hotel, perhaps a version of David Deutsch, before it's too late? Would that act save me from non-existence and if so at what point must I bite before it's too late? If I do bite one of those hotel guests, making them drop me before they can pass me on, in what direction should I run so as not to cease to exist? If I run along the corridor in the same direction and at the same rate as I was being passed from room to room by the guests would I still cease to exist at some point? Would I never find my way out of the corridor of Infinity Hotel, and if so should I keep shifting my running directions so as not to cease to exist? Would the safest option be to remain static and chase my tail for amusement and exercise? But if that is the safest option then what is the difference between dogs existing in Infinity Hotel and human civilizations ceasing to exist due to their static thinking? In short, please tell me more about the poor darn dog so that the written explanation for the theory makes more sense and so that I can try to square it with other knowledge in this book about successful and unsuccessful societies. Let me explain further what I meant by that last sentence and why the question about the dog troubles me. Deutsch makes a compellingly rational argument that good ideas have infinite reach. He goes on to make a brilliant contribution - through the clarity of his explanation of Richard Dawkins' theory and his own ideas on the subject - to our understanding of memes. To digress, it was this part of his book that sparked my own idea, as a criminologist, that perhaps crime is the ultimately selfish meme. For those unfamiliar with the concept, memes are ideas that survive in human culture in the same way as genes in do in living matter by selfishly passing themselves on. The Christian religion, for example, is a meme. Ok back to my confusion, so what I can't understand from reading Deutsch's written explanation of infinity is what would happen in David Hilbert's Grand Infinity Hotel (see: Olein 2001 for the story behind Infinity Hotel) if it was an idea (a meme) that was so complicated it had to be written down was passed along from room to room rather than a dog? If that idea was a good explanation for infinity, according to Deutsch's explanation it could not have infinite reach because at some point along the infinite corridor of knowledge in Infinity Hotel the brilliant but complex idea would cease to exist. In that case how would it still have the capacity for infinite reach if it ceased to exist somewhere further along the infinite corridor of knowledge as a singularity? Infinity Hotel, which can always accommodate more infinitely countable guests even when it is full but it cannot accommodate good explanations that are so complex they have to be written down to be passed on as memes. This leads me to ask the following question: Does the fact that good physically recorded explanations, just like other physical objects such as dogs, do not have a fundamental place and are not unlimited in their scope and power within the brilliant mathematical world of Hilbert's Grand Infinity Hotel have any significance for Deutsch's massive paradigm shifting claim that 'explanations' have a fundamental place in the universe? I am not so self-deluded as to suppose that the above questions pose any kind of paradox that Deutsch will now have to deal with. Rather, I suspect I've made some kind of naive mistake in asking these questions - perhaps something close to Zeno's mistake (which Deutsch explains well). But that is my point, the book is written as much for non-quantum physicists as it is for them. Indeed, all the explanations are written in text, which is good because I hate equations and can't make head nor tail of most of them. But that leaves me with this Dog Dilemma, so that I'm now, in my ignorance as a social scientist, left awake at night to wonder whether there is a dog. Infinity Hotel is obviously an analogy, but unless the analogy can tell us more about these obvious 'what happens if and why' questions about Deutsch's dog then as Deutsch himself teaches us in this book: "Arguments by analogy are fallacies. Almost any analogy between any two things contains some grain of truth, but one cannot tell what that is until one has an independent explanation for what is analogous to what and why." (p.371) As far as vanishing dogs and annihilated memes go in Infinity Hotel, I'm not sure Deutsch does make such complexities explainable to the person in the street. Another criticism that I do have is that when he first begins to write about abstractions Deutsch assumes the reader knows both what an abstraction is and what type of abstraction he is thinking of. Once you read Deutsch's remarkable book, those past few paragraphs might not read anything like as crazy as you may think they are. If you can think then I think that this book should change the way you think about thinking forever. I did find the imagined ancient Greece philosopher's dream chapter very boring and so I skipped it because it seemed to have nothing new to add to what Deutsch had already explained in his careful and elegant explanatory prose. But that's it for personal negative criticisms and my personal confusion. Because overall, this is - as so many others are saying - going to be a classic book. But wait. No! That's a prophecy and not a scientific prediction. So, I'm being irrational now and I could easily be very wrong. Why? Well, you'll have to read the book to find out. I would willingly place a large wager on Professor David Deutsch - with this remarkable explanatory text - going on to inspire and guide an infinity of future thinking and knowledge progression. Deutsch is today the man to beat as the world's greatest living universal explainer. One day I would like to know his thoughts on Lovelock's Gaia Theory and on the whole notion of self-regulating complex systems - be they physical or social. Besides the Kindle edition, I bought my hard copy of this book only three weeks ago and it's a first edition. Do you know what a first edition of Darwin's Origin of Species fetches today? I feel like going out and snapping up another 100 of the printed version for my pension fund. Reference Hilbert, D. (1900) Mathematical Problems.

    I have no science background (except college biology) and my own reading, so my understanding of The Beginning of Infinity is somewhat limited (particularly the chapter on the multiverse). But even with that limitation, I found this to be one of the best books I've read in years in terms of developing and pushing my own understanding of the world. I reread two chapters just to try to get some inkling of their meaning (the multiverse and the jump to universality). I also read the infinity chapter twice and on the second reading I finally got the point of the infinite hotel (or at least one point). Even after two reads though, with those chapters I still felt lost. I really need to reread them all, but this is my review with just one reading.

    Despite my ignorance, I still felt it worthwhile to write a review to encourage others who might think that this book is not for them to tackle it. It is worth the effort to comprehend even for those who are not versed in the sciences.

    This is what I understood from the book. Deutsch argues that we are at the "beginning" of the creation of good explanations about our world (the infinity of the title is the endless knowledge that humans have the potential to create). We will always be at the beginning (such is the nature of infinity I think--at least that's what the infinite hotel suggested), and this leads to optimism about our world. Our world is filled with (overflowing with might be a better way to think of it because we don't even really know where the world ends)problems and potential solutions. Through conjecture and criticism, humans "solve" many of these problems and this leads to new problems (solutions are not truths but they are the best explanations for the problem after much testing--and stand as objective truths, I think).

    D systematically builds his case, looking at other science approaches like empiricism or instrumentalism and shows why these are not good explanations. This is not an attack on alternative perspectives as much as it is the building of good explanations around the topics that are discussed (which range from beauty (D argues that beauty is objective), philosophy, psychology, elections, choices, creation and physics). There seems to be rhetorical room for disagreement, meaning that D posits his position, criticizes the other positions and then argues that his position currently stands up to available criticism. Again, the criticism isn't an attack though; it's how knowledge is created. D's conjecture and refutation approach (to use Popper's terms) seems to make so much more sense then the usual way arguments are presented: here is a claim, here is why you should believe my claim, because I have lots of support for my claim you, the reader, should agree I'm right. Even if you have 500 pages of support for your claim, one piece of criticism could refute it.

    What I found most beneficial to me was the emphasis on optimism. Humans are great creators, testers and explainers. That's exciting. I still don't understand how to apply the theories and truths discussed here to human behavior, however. Deutsch does mention psychology and its bad theories, but I'm not really talking about that. I'm wondering if humans can achieve all possibilities that do not defy the laws of physics,and does this mean things like balancing the budget? Or agreeing on good laws? How does the human ability to develop good explanations work in these instances? Deutsch (referencing Popper, who he references a lot)states that reforming politics is more a matter of setting up laws that allow us to get rid of bad rulers and bad laws (as opposed to trying to somehow fix the system to make sure only "good" politicians got elected, or good laws passed). Is the assumption that if those laws were in place than politicians would develop/accept good explanations for fear of being got rid of (or would we just end up overturning things over and over again? Now I'm prophesying which D condemns; what could we predict about human behavior? that is really the question . . . ). Do the principles raised in this book work with human behavior just as they do with physical and technical problems?

    Deutsch starts with some fundamental principles (lots more than the ones I'm listing but these are what stood out to me and that I remember):
    1. there is no authoritative way to knowledge
    2. Humans are unique; what makes us unique is our ability to criticize our ideas and to generate new ones
    3. The best knowledge for anything is a good explanation (we ask, is this the best explanation?). Good explanations are the ones that withstand heavy and sustained criticism
    4. All observation is theory driven
    5. evolution favors the genes that can spread through the population
    6. morality, beauty, abstract concepts exist objectively (through good explanations)
    7. the laws of physics determine mathematical principles
    8. The universe is not random; but determined by the laws of physics.
    9. prophecy is bad explanation; prediction from good explanation is better
    10. Humans are creative but we have to be open to our creativity in order to feed it (the enlightenment was the first large scale example of this). We have to recognize that problems exist, that people can solve them and that this is the best plan for humans.

    When I finished I had lots of questions. I don't really get the concept of "fine tuning", and I don't understand the multiverse at all. I understand what the words say, but I can't get my head around the idea of these multiple planes and people all existing simultaneously and then when he starts talking about the photons hitting the plate and going off I get really lost.

    Not sure I get the anthropic principle. I did go do more reading on it and what I understood it to mean was that human existence (that humans are here) puts limits on the explanations for our existence. I think D disagrees with this.

    A final wondering. . . Deutsch doesn't really address emotions. Emotions, particularly fear, seem to power much human behavior (and certainly the stagnancy he discusses that kept us from moving forward with our creativity). In the rational world offered by this book, how do people "deal with" emotional resistance? Perhaps Deutsch would say that question isn't really relevant. There are good explanations for why emotion overpowers reason (I think they are good, but maybe they aren't--such as the part of our brains that powers emotions is much more powerful than that which powers reason), but such explanations do not help us to overcome this problem.

    In a day and age when fear appears to be a primary commodity our politicians, media and economists try to sell us, we forget the progress we have made in the last few centuries. In the sixteenth century, Galileo demonstrated that it was possible for everything on earth to be moving through space at breakneck speed while appearing to us to be at rest. In the seventeenth century Newton put forth theories of planetary motion and with Leibniz invented calculus. In the 18th century, the foundations of modern chemistry and geology were established. In the nineteenth century, the telegraph was invented marking the first time the message could outdistance the messenger; Darwin put forth his theory of evolution establishing modern biology; the world of microbes was unlocked (with all the advances in medicine that event enabled); electricity turned night into day in an unprecedented way. The twentieth century, well . . . it would take volumes to list the advances in the twentieth century most of which were not and possibly could not have been predicted at the beginning of the century because, as this book often points out, we cannot predict innovation. David Deutsch reminds us of these indisputable facts, and creates a vision of our future that is both optimistic and realistic. It is optimistic in the sense that our progress is infinite. It is realistic because he recognizes that we will always have problems, and, indeed, often (but not always) these problems will be a consequence of our solutions to older problems.

    There is only one way of thinking that is capable of making such progress and this is the way of seeking good explanations though creativity and criticism. The better an explanation, the more extensive is its range and the more difficult it is to construct an better, alternative explanation. Parochial theories (theories that may apply rules of thumb to local situations, but then often claim universality) always resist explanatory knowledge. Parochial knowledge seeks to be justified by one external authority or another. It has taken the form of a parent saying, "Because I said so" or a church leader saying, "Because God says so" in order to justify one belief or another. Cultural memes often provide the same sort of parochial explanations that resist knowledge that seeks good explanations.

    Good explanations are not limited to the sciences, and they are important because they have infinite reach. Deutsch describes this infinite reach and contrasts it with parochial theories in many ways throughout the book. One example -which he does not use- might be a brief contrast between the physics of Aristotle and Galileo. Aristotle's physics was based on rest. It was based on rest because he thought that the earth rested at the center of the cosmos. Objects fell (or were elevated) because of their weight (in Latin the word for weight is gravitas). The heavier the object was, the closer it was to the center of the cosmos. The lighter it was, the further away from the center its natural place was. There is more to Aristotle than this, but the point is that Aristotle's theory was parochial. It pertained only to the earth and it did not have infinite reach. Indeed, according to Aristotle, the celestial bodies were so light (actually they had no weight) that they were not made of the same material as that on the earth. As a consequence, celestial bodies were not subject to the same physical laws as bodies on earth. Galileo explained it differently. Following Copernicus, Galileo did not think the earth was the center. His physical theory was based on motion not rest. Accordingly, his theory applied to the planets and stars as well as the earth. Galileo was at the beginning of infinity. His speculations launched us on a path that could not have been predicted. Over the years his theory was subjected to a variety of criticisms and progress was made that exceeded even his wildest imagination. Good explanations, like Galileo's, always place us at the beginning of infinity, and The Beginning of Infinity is the title and theme of this remarkable book.

    Deutsch spends much valuable time discussing obstacles to knowledge based on good explanations such as bad philosophy, justifications based on authority, memes that impede good explanations, political systems that close debate, etc. In each case, he gives hope for the human enterprise so long as we have the will to stand at the beginning of infinity.

    A solid read. Perhaps a bit too long and too smart, at least for me, but intriguing nonetheless. We do solve problems and in the process create knowledge, much like the universe itself the body knowledge is expanding and the creation is accelerating. So, it does look like the beginning of infinity. And yes, the author's favorite word does seem to be - parochial 🙂

    Lo compré porque aparentemente Mark Zuckenberg lo recomendaba. Al escuchar eso me pareció una tonteria comprarlo, pero espero valga la pena (sólo llevo 60 páginas). La razón por que me animé a comprarlo es por el autor, el es físico como yo. Al leer eso, me pareció importante darle una oportunidad.

    Por el lado malo, me molesta un poco la postura del autor, ya que en ratos parece un poco pedante corrigiendo a figuras como Thomas Alva Edison y Richard Dawkins, argumentando que la postura de ellos es "incorrecta" respecto a lo que él cree.

    Aún no lo acabo de leer, así que no se si lo volvería a comprar :P

    Reviewed in Japan on July 15, 2015

    I loved this book, but this didn't surprise me, as I found the author's previous book, The Fabric of Reality, equally entertaining and thought provoking. I am not an expert in quantum mechanics or quantum computing. The little I knew about the topic always gave me an unease regarding the inherently probabilistic features of them. Deutsch provides a clear and deterministic explanation to quantum phenomena, which to me sounds quite intuitive despite the claims in several other books to the highly counterintuitive nature of quantum mechanics.
    However, in the book this interpretation is of secondary importance to the all encompassing theory of knowledge as the main driving force in the evolution of the universe. I completely agree with the author on the importance of good explanations and that good conjectures precede 'conclusions drawn from experiments'. Read this book even if you don't agree with the many worlds interpretation.
