HOW OUR PLACE IN THE COSMOS
IS DESIGNED FOR DISCOVERY

Synopsis

The Provocative Classic The Privileged Planet in a Fully Revised, 20th Edition!

Are we just an accident of cosmic evolution? Is Earth a “lonely speck in the great enveloping cosmic dark” as the late Carl Sagan put it? Or is there more to the story? In this provocative book, Guillermo Gonzalez and Jay W. Richards marshal a staggering array of scientific evidence to counter the modern dogma that Earth is nothing more than the winner of a blind cosmic lottery.

When The Privileged Planet was first published in 2004, it garnered both praise and rage. But its argument has stood the test of time. In this completely revised 20th anniversary edition, Gonzalez and Richards show how thousands of discoveries of extrasolar planets over the last two decades have only strengthened their case.
 
They take readers on a mind-expanding journey through our solar system and beyond. Along the way, they explore the mystery of total solar eclipses, the crucial role of water and carbon, the fine-tuning of physics that makes advanced life possible, and the beginning of cosmic time. From our cozy blue planet to the edge of the known universe, they show how earthlike planets are exquisitely fit not only to sustain life but to provide the best platform to discover the hidden wonders of the cosmos.
 
The Privileged Planet compels us to reconsider our place in the universe. Far from a cosmic fluke, our world is ingeniously designed not just for life but for discovery.

First Edition Synopsis

For centuries scientists and philosophers have marveled at an eerie coincidence. Mathematics, a creation of human reason, can predict the nature of the universe, a fact physicist Eugene Wigner referred to as the “unreasonable effectiveness of mathematics in the physical sciences.” In the last three decades astronomers and cosmologists have noticed another, seemingly unrelated, mystery. Contrary to all expectations, the laws of physics seem precisely “fine-tuned” for the existence of complex life.

Could these two wonders actually be isolated pieces of a wider pattern? Both are prerequisites for science, yet what about the process of scientific discovery itself? What are its necessary conditions? Why is it even possible? Read any book on the history of science, and you’ll learn about magnificent tales of human ingenuity, persistence, and dumb luck. But that’s only part of the story, and not even the most important part. Our location is much more critical to science than it is to real estate. For some reason our Earthly location is extraordinarily well suited to allow us to peer into the heavens and discover its secrets.

Elsewhere, you might learn that Earth and its local environment provide a delicate, and probably exceedingly rare, cradle for complex life. But there’s another, even more startling, fact, described in The Privileged Planet: those same rare conditions that produce a habitable planet-that allow for the existence of complex observers like ourselves-also provide the best overall place for observing. What does this mean? At the least, it turns our view of the universe inside out. The universe is not “pointless” (Steven Weinberg), Earth merely “a lonely speck in the great enveloping cosmic dark,” (Carl Sagan) and human existence “just a more-or-less farcical outcome of a chain of accidents” (Steven Weinberg). On the contrary, the evidence we can uncover from our Earthly home points to a universe that is designed for life, and designed for discovery.

Reviews

Is our universe a blind concatenation of atoms, evolution a random walk across a meaningless landscape, and our sense of purpose a pathetic shield against a supremely indifferent world? Or does the universe and our place within it click into place, repeatedly? These starkly different views open up immense metaphysical and theological questions, and at least part of the answer must come from science and the unfolding triumphs of cosmology, astronomy, and evolution.

In a book of magnificent sweep and daring Guillermo Gonzalez and Jay Richards drive home the arguments that the old cliché of no place like home is eerily true of Earth. Not only that, but if the scientific method was to emerge anywhere, the Earth is about as suitable as you can get. Gonzalez and Richards have flung down the gauntlet. Let the debate begin; it is a question that involves us all.

This thoughtful, delightfully contrarian book will rile up those who believe the “Copernican principle” is an essential philosophical component of modern science. Is our universe designedly congenial to intelligent, observing life? Passionate advocates of the search for extraterrestrial intelligence (SETI) will find much to ponder in this carefully documented analysis.

Not only have Guillermo Gonzalez and Jay Richards written a book with a remarkable thesis, they have constructed their argument on an abundance of evidence and with a cautiousness of statement that make their volume even more remarkable. In my opinion, The Privileged Planet deserves very careful attention.

Impressively researched and lucidly written, The Privileged Planet will surely rattle if not finally dislodge a pet assumption held by many interpreters of modern science: the so-called Copernican Principle (which isn’t actually very Copernican!). But Gonzalez and Richards’ argument, though controversial, is so carefully and moderately presented that any reasonable critique of it must itself address the astonishing evidence which has for so long somehow escaped our notice. I therefore expect this book to renew—and to raise to a new level—the whole scientific and philosophic debate about earth’s cosmic significance. It is a high class piece of work that deserves the widest possible audience.

Gonzalez and Richards have written a book that is at once inspiring, illuminating, and beautiful. Although the 20th century insights in quantum physics should long ago have dispelled the simplistic idea that nature is nothing more than matter in motion, The Privileged Planet suggests that scientific discovery is embedded in the very structure of the cosmos. With uncommonly engaging prose, they offer a virtual tour of the marvels of modern science and the discoveries science has brought to light, from geology to cosmology. The authors also suggest intriguing answers to ubiquitous “cosmic questions”: Why have we been able to discover so much about the world around us in such a short time? Is extraterrestrial life common, or is it quite rare? What is Earth’s place in the cosmos? Does the universe exist for a purpose? Only those interested in these questions — but who isn’t? — should read this book.

In this fascinating and highly original book, Guillermo Gonzalez and Jay Richards advance a persuasive argument, and marshal a wealth of diverse scientific evidence to justify that argument. In the process, they effectively challenge several popular assumptions, not only about the nature and history of science, but also about the nature and origin of the cosmos. The Privileged Planet will be impossible to ignore. It is likely to change the way we view both the scientific enterprise and the world around us. I recommend it highly.

Privileged Planet is simply a beautifully written piece of work: so lucid and compelling in its presentation that even the most lay of laypersons will fly through its pages, barely able to put the book down. And when is the last time that hard science has delivered such an optimistic, even joyful message? For Gonzalez and Richards have made the incontrovertible case that this earth of ours is not just some flyspeck of inconsequentiality in a meaningless universe, but holds a rare, even honored place, and that we, its inhabitants, are especially privileged to be here.

Q&As

Q#1: Is the fact that we can see “perfect” solar eclipses related to our existence?

A: The Earth’s surface provides the best view of solar eclipses in the Solar System. The Earth’s surface is also the most habitable place in the Solar System. Is this coincidence just that? In The Privileged Planet, we argue that it isn’t. The conditions that make a planet habitable also make its inhabitants more likely to see solar eclipses.

Q#2: Is our existence related to the transparency of the atmosphere?

A: Atmospheres come in many forms, but not all allow for complex life or clear views of the wider universe. Complex life requires a certain type of atmosphere. It turns out that this same type of atmosphere provides a remarkably clear view of the near and distant universe. Complex, intelligent beings are unlikely to find themselves on a planet with an opaque atmosphere or deep in a murky ocean. We explain this relationship in detail in The Privileged Planet.

Q#3: Can life be based on any liquid substance, or is water somehow special?

A: Water is common on Earth’s surface, but one might suspect that on other planets, there are complex, intelligent beings that are not based on water, but liquid ammonia, methane, or nitrogen. But that’s very unlikely. As it turns out, water is endowed with life-support capacities lacking in other substances. Together these capacities make water the most anomalous compound known to science. In The Privileged Planet, we also explain how important water has been to the rise of science.

Q#4: Is Earth a data recorder?

A: A walk through a Redwood forest is like a walk through the Library of Congress. Trees, along with corals, polar ice, marine sediments, and lake sediments contain vast storehouses of detailed information about Earth’s past climate. Is this a typical feature of planets? On the contrary, we argue that, as planets go, Earth (or, more precisely, the Earth-Moon system) is a quite high fidelity recorder of the past.

Q#5: Is the appearance of the night sky related to our existence?

A: Not only is our atmosphere transparent, but we also enjoy dark nights. Several happy coincidences, from having a planet that rotates on its axis, to our location in the galaxy, to the age of the cosmos, conspire to make this possible. And those dark nights have been vital to many scientific discoveries, as we argue in The Privileged Planet.

Q#6: Why are there so many planets in the Solar System?

A: Isn’t just one planet (Earth) all we need? Doesn’t it seem like a waste of space and materials to have all those other barren worlds? Well, not if those worlds are players in the games of life and scientific discovery. In The Privileged Planet, we discuss how the other planets serve as Earth’s protectors while at the same time helping us in our quest to learn about the nature of the cosmos.

Q#7: Did Copernicus remove us from the center of the cosmos?

A: In most introductory astronomy textbooks and popular descriptions of the history of science, students are told that until Copernicus, the West believed that Earth and its human inhabitants viewed themselves as being in the most important place in the cosmos. Copernicus, we are told, demoted us by making Earth merely one of the planets. As it is usually presented, this popular story is mostly mythology rather than historical fact. In Pre-Copernican cosmology, the “center” of the cosmos meant something entirely different from what it is now taken to mean. We explain why in The Privileged Planet.
