Dyson reflects here on the 'dome of many - colored glass that stains the white radiance of eternity' our richly varied world. He shows a commendable humility in his reflections on the place of life in the Universe. Originally given as public lectures to a scientifically literate public Dyson opens with a consideration of problems of biotechnology.
In one section he writes about three heresies he espouses, one in which he suggests that global warning is not perhaps the awesome danger many see it to be. In another reflection he speaks about the divisions between 'humanists' and 'naturalists' the latter being those who wish to preserve 'nature' and believe nature's way superior. He talks about his own native England about the poverty of the natural landscape until human beings transformed it to the land of meadows and moors, of pastures and green farmland. He considers himself a 'humanist' who believes that mankind's mission is too in transforming nature for the better. And this though of course he is aware of the dangers of this, of those we have created for ourselves. In another realm he speaks about his belief that the U.S. is about to be replaced as the world's major power most likely by China but perhaps by Brazil or India. He suggests that about one- hundred and fifty years is all the time a major nation can be predominant before it becomes over- extended in every way. He suggests the U.S will reach this point around 2070.
In speaking to young people about the future he warns about rapid changes making obsolescent the professions and work they have trained for. But he concludes with a modest and somewhat optimistic word of advice to them.
"The main lesson that I would like them to take home is that the long-range future is not predetermined. The future is in their hands. The rules of the world-historical game change from decade to decade in unpredictable ways. All our fashionable worries and all our prevailing dogmas will probably be obsolete in fifty years. My heresies will probably also be obsolete. It is up to them to find new heresies to guide our way to a more hopeful future."

This book is a rare delight.

There are two types of science books. Most explain how and why we know something about what we know. The other questions what we assume we know, which is generally the path to new, expanded and sometimes very new fields of scientific knowledge.

Al Gore, for example, who realizes no one gets major headlines by being modest or unsure about one's ideas, says we must end our reliance on fossil fuels within a decade. Dyson says, in effect, wait a minute, we're already overdue for an ice age, maybe global warming is keeping us from freezing.

In contrast to Gore's certainty, Dyson questions, probes, doubts and considers alternatives. In a world overun by people who are dead certain about politics, progress, art, theology, music and almost everything, it's a treat to find educated and thoughtful ideas by someone who admits, "I am trying to reconcile the theoretical law of increasing disorder in the universe with the evidence for increasing order in the universe as we observe it."

On that basis, Dyson will upset people who know things.

Granted, once upon a time he was young, immature, impatient and brashly confident of his wisdom. In 1945, when he was 22 years old, he advised Francis Crick not to give up physics in favour of a new career in biology. Fortunately, Crick didn't take Dyson's advice; instead, within seven years he discovered the double helix structure of DNA which gave birth to molecular genetics.

Suffice to say, Dyson learned, "Even a smart 22-year-old is not a reliable guide to the future of science. And the 22-year-old has become even less reliable now that he is 82."

Great stuff, if you like the idea that science is a continual search for knowledge and not a platform for politically correct dogmas. Science doesn't freeze what little we believe is true into rigid orthodoxies that cannot be doubted, challenged or modified.

Dyson writes that it is the poets who sometimes have a greater insight into science, such as William Blake, who was once "this crazy poet" but who also invited us

"To see the world in a grain of sand
And a heaven in a wild flower,
Hold Infinity in the palm of your hand
And Eternity in an hour."

Fortunately, those who see more and question more than most in today's world are not crazy. They are merely gifted with a different and sometimes better insight. From them we learn new concepts, or strengthen our own ideas. This intellectual approach creates a rare book when someone such as Dyson share ideas in a clear, concise and provocative style. This book is a dialogue of ideas.

It begins with philosophy of the fox and the hedgehog by Isaiah Berlin and Archilochus, and ends with a beautiful portrait of an autistic child who grew into a wonderful woman. This delightful tour of ideas, questions and observations closes with the thought "... there may be more things in heaven and earth than we are capable of understanding."

I picked up this book to read Dyson's commentary on climate change/global warming, as I heard he was a climate change skeptic. His commentary on climate change is terrific. But there's much more to this book than just climate change--he covers life in the universe, scientific skepticism, religion, and a number of other topics. This is the work of a brilliant, profound thinker. Well worth the price.

Dyson writes well enough, but this collection of essays is hit and miss. I feel a bit out of turn being overly critical or analytical of such an accomplished physicist, philosopher and thinker, but there are some profoundly naive and superficial conclusions and reasoning in a couple of the essays that distracted from the brilliant thoughts in some of the others, particularly the sections on the "Friendly Universe" in which Dyson tries to rationalize the paradox of order in a world dominated by the second law of thermodynamics and its tendency toward disorder and the essay on the search for extraterrestrial intelligence.

What does work is that Dyson is tremendously well-read and deeply thoughtful in fields outside theoretical physics. One might argue that a lot of his speculations into biotechnology and other fields are the equivalent of an amateur poking around and considering himself an expert, but this isn't so. He's very clear and direct about his lack of knowledge and that his speculations are just that. In that respect he differs from a lot of "futurists" who publish books like "The World in 2050" in which they proclaim flying cars for everyone! (I'm still waiting for the one my grandmother promised me I'd have by the time I was twenty when I was ten.) He's realistic about the time frames for his speculations about the development of technology and the future of discovery in the realms of science. Dyson, quite rightly given the enormous mathematical and technological complexities of advances in particle and theoretical physics today, thinks that biology and biotechnology will dominate the sciences in the next hundred years. There are some heretical ideas in his speculations. Most intriguing among his predictions (or desires) is the development of an open source equivalent to genetic sequencing and engineering and the idea that science shall proliferate among the masses and become smaller, more diverse and given over to small teams versus larger research institutions, in both the physical sciences, like astronomy (where we can already see this happening) AND in biology. It's an interesting and exciting thought. Science could indeed progress by leaps and bounds as more people, especially those not brought through decades of rigorous academic dogma in specific Ph.D. programs bring new unorthodox methods and ideas to the table - and can test and verify them themselves. I don't know if I'd go so far as to say that in the future genetic engineering will occupy the entertainment time of children the way video games do today, but the idea of science for the masses is thrillingly conceivable.

In short, Dyson's strength in this work rests in his ability to combine disciplines and draw parallels among opposite and paradoxical fields and models to develop new and believable paradigms for the future grounded in our experience with scientific revolutions and developments in the past. The last essay on the complementarity of religion and science is refreshing, enlightening, but half-formulated sadly. He starts off well and drifts off to the idea that literature has much more in common with religion where there was so much potential in the former idea. And that's kind of the point; Dyson's great at asking broad, philosophical and practical questions alike and A Many-Colored Glass should definitely be required reading in philosophy of science courses around the world. It's the questions, rather than the answers he presents that make this book valuable.

I was disappointed by a couple of the heavier essays in the work that I was looking forward to immensely. The chapter on the search for extraterrestrial life is extremely narrow and falls prey to the same weaknesses that the chapter on religion did. He starts with some great questions about what life might look like and what type of life might be most common to practically tailor or search for it, then goes into an overly detailed and narrow plan to execute said-search. Same goes for the essay on Life in an old universe tending toward heat death, in which he sets up a great framework, but fails to deliver and bungles an explanation of entropy.

Still, if you have an interest in the philosophy of science or want to hear a respected scientist's views on the future of the field, this is an interesting read.

Freeman Dyson is one of the most forward thinking people of the last 100 years. For some book review to simply dismiss his resume out of hand is absurd. This is a complex issue that demands we think with our heads and not with our hearts. The study of this issue requires that those familiar with the complex mathematics involved have a say so, and not just climate scientists with only a cursory understanding of the machinations of their climate models....twhair@fgcu.edu

I have read most if not all of Freeman Dyson's books, starting with Disturbing the Universe and on to A Many Colored Glass. All were delights. His writings are notable for his style and clarity. The Chapter on Heresy was especially thought provoking. I certainly might preser a climate where the "Sahara is wet".




EDITOR AMAZON. I HAVE BOUGHT MANY THINGS AND BOOKS FROM AMAZON, INCLUDING BOOKS BY F. DYSON. I AM NOT SURE THAT THIS BOOK IS ONE COMING FROM AMAZON. I FIND IT TAWDRY TO REQUIRE ME TO VERIFY THE PURCHASE OF A SPECIFIC WORK. I WROTE THE REVIEW BEFORE I FIND ITS A PRODUCTION PLOY FOR AMAZON. I REVIEW ON THE UNQUESTIONED VALUE OF THIS TEXT.

I TOTALLY REJECT USING ME AS A VEHICLE TO PUSH AMAZON AGENDA.

JOHN W BROOKBANK, PhD (California Inst. of Technology) I won't be looking for it in any of your attachments.

Crystalline writing and thinking in this book that goes beyond disciplinary boundaries.
