Review
"John Leslie ... has written far and away the best book about the anthropic principle.""
-John Polkinghorne, President of Queens College, Cambridge University
"It is important . . . to have the fruit of Leslie's work, across two decades, summarized in one accessible book of manageable length, seriously argued but neither overly technical or esoteric . . . Written with a good deal of philosophical courage and much originality, virtues rather rare in contemporary philosophy."
-"Zygon
"A highly original, powerfully argued book that reveals a thorough knowledge of contemporary physics and cosmology."
-Quentin Smith, "Nous
"An exciting and important book. For, by developing a new and far more powerful form of Argument to Design, it effects a revolution in or . . . a resurrection of National Theology."
-Anthony Flew, "Philosophical Books
From the Back Cover
Universes asks 'Why does our universe exist?' In order to answer that most fundamental of question, this author examines the philosophical as well as the scientific arguments for 'fine tuning'; that is, the theory that the cosmos is specifically suited to produce life. The result is one of the most powerful versions of the 'argument from design' in this century.
About the Author
John Leslie, Professor of Philosophy at the University of Guelph, is the author of The End of the World (Routledge, 1996) and Value and Existence (1979) and the editor of Physical Cosmology and Philosophy (1982).

The DEFINITIVE book on the Anthropic Principle
By D. Roberts
This book is truly wonderful. Not only that, it is perhaps the only book that I know of that is endorsed by BOTH atheists and theists alike. Yep, that's right boys and girls. Quentin Smith is one of the most die hard atheists on the planet and Peter Van Inwagen of the university of Nortre Dame is one of the biggest defenders of theism. Both rave about this book and their comments can be read on the back cover. So, what is this book all about, you ask? Well, it's something known as the Anthropic Principle. It was first introduced in the early 1970s by a physicist by the name of Brandon Carter. It basically states that we are not just lucky to be here, but rather we are REALLY REALLY REALLY REALLY lucky to be here. Why? Because from the first instant of the big bang onward, an incredible and highly improbable slew of things HAD to go right in order for the possibility for life to exist anywhere in the universe. So much so that it seems that the universe was "fine tuned" just for life. Sir Fred Hoyle (an atheist) was led to comment that the universe looks like a "put up job." Now, this set of circumstances led to a ressurection of the Argument from Design by the theists with renewed vehemence. Meanwhile, the atheists have their own responses, which basically take up two camps. First Response (also known as the Weak Anthropic Principle or WAP): "Of course the universe has laws which allow life to exist. If they didn't we would not be here. Therefore, the odds are irrelevant except perhaps for some latenight philosophic mental gymnastics." Now, there is a problem with this response in that it is nothing more than a tautology. That is to say, it does not EXPLAIN why the universe supports life despite so many constricted laws of physics and chemistry. It is like someone asking why the Dallas Cowboys won the superbowl and having a person respond "because they scored more points than the other team." That answers nothing. The question is: WHY did they win? Were they better than the other team? Did they get lucky? Did they have a better coach? Did the other team have injuries? Were turnovers a factor? etc. etc. Saying that "they scored more points" only states the obvious: "of course they scored more points, or else they would not have won the game..." Now, the second camp is known as the Strong Anthropic Principle (SAP) and it goes something like this: "Since the odds of our existing in a universe with the PRECISE physical laws necessary for us to do so are so slim as to be intellectually unacceptable (in the order of 10^10^123 according to Roger Penrose) there must then be a whole slew of other universes (perhaps an infinite number) to JUSTIFY this one. That is to say, in an infinite number of universes, virtually anything can happen. The majority of them would have random, weird laws of physics and be lifeless but EVERY SO OFTEN you would get one which could support life (in some form or another)." Now, this is an interesting argument, but it has a fatal flaw. There is not a SHRED of evidence that even one other universe exists besides our (much less an infinte number of them). Yet they seem to HAVE to exist in order for the numbers to come out right. Hence, if one chooses to believe in these alternate universes (no matter what his scientific credentials) he MUST do so on faith alone. Obviously, most atheists are not comfortable with this conclusion, but that is the way it goes. Leslie's book engages the subject objectively and he tells wonderful, fun stories that offer both the atheist (multiple universe) and theistic (one universe with a designer) perceptions of the debate. A remarkable book. I think that Mr. Pierson missed the point when he read it as it is not about Darwinian evolution at all (nor does Leslie ever say it is). It is well worth reading the whole thing, too. What Mr. Pierson said about atheists being willing to believe in multiple universes but are not willing to believe in God is precisely one of Leslie's points. However, I also would endorse the other books that Mr. Pierson recommended as I have read them too. Also, I would suggest for those who like this book Atheism, Theism and Big Bang Cosmology by Quentin Smith and William Craig Lane.

Cosmology made Fun and Exciting
By A Customer
Philosophy professor John Leslie does a supurb job of presenting evidence that our cosmos may have been "fine-tuned" for life. The basic argument is that a life-premitting cosmos requires the existence of a very large number of highly specific and seemingly unrelated facts. Were any of these facts changed even modestly, life could have never have arisen. Further, since the probability of all the facts being what are is thought to be vanishingly small, some have suggested that our cosmos may have been "fine-tuned" for life. For some this has seemed a strong argument for the existence of God. But Leslie points out that an equally good explanation is that our portion of the cosmos is only a small part of a vast Universe. The great majority of this Universe is disorded and non-life-premitting, but entirely by chance some portions are life-premitting. That we see a life-permitting cosmos should come as no surprise, because mere chance indicates that at least some areas should be life-premitting and we can exist only in these areas.
While Leslie's work is fun and exciting, and while Leslie clearly knows a great deal about physics and cosmology, from a philosophical perspective some of his conclusions seem a bit naive. For example, he defends a bizarre neoplatonic notion that a life-premitting Universe may exist solely because its existence is ethically required, i.e. that an abstract ethical principle may somehow have created everything. While this is a possible cosmogony perhaps on par with the God hypothesis, its implausable nature seems to suggest that we adopt a healthy skepticism about the ultimate origins of the Universe rather than seriously entartain it as a possibility. Leslie also makes some unwarranted assumptions about the possibility of alternative laws of nature. Nonetheless, the book is fun and informative. I highly recommend it. --Greg Klebanoff

A CANADIAN PHILOSOPHER CONCLUDES THAT BOTH GOD, AND "MANY VARIED UNIVERSES" ARE POSSIBLE
By Steven H Propp
John Andrew Leslie (born 1940) is a Canadian philosopher, who is currently Professor emeritus at the University of Guelph, in Ontario, Canada. He has written other books such as The Mystery of Existence: Why Is There Anything At All, Immortality Defended, Infinite Minds: A Philosophical Cosmology, etc.
He wrote in the first chapter of this 1989 book, "Rightly or wrongly, this book shows no interest in the kind of God who designs the structures of individual organisms... or who interferes with Nature's day-to-day operations. If God exists then ... there are only two ways which will be considered in these pages. First, he makes the universe obey a particular set of laws... Second, he creates its initial state in such-and-such a fashion." (Pg. 2)
He makes an argument, "Let us agree that in God's absence our births could only be a matter of tremendous luck. Let it be supposed that if ... Nature's four main forces had occurred slightly differently in our universe than living beings could never have evolved in it... So what? The hypothesis of many universes shows how it could be likely that SOME set of living beings should have the luck of being born. While they would be extremely lucky, their luck would not be unbelievably amazing." (Pg. 12) He continues, "the existence of countless universes may well have made it virtually sure that at least one universe would become 'ours' to living beings..." (Pg. 15)
He states, "Why believe in other universes when we cannot know of them directly? It could only be because we can INDIRECTLY know of them or at least gain good grounds for suspecting their existence... there are two fairly strong excuses for believing in universes in large numbers... mightn't it be absurdly complicated to think of this [Big] Bang as the only one ever to occur in that fashion?... The visible universe is not nearly dense enough to end at precisely those limits if General Relativity is even approximately right... The second excuse ... [is that] the present of vastly many universes very different in their characters might be our best explanation for why at least one universe has a life-permitting character." (Pg. 69-70)
He points out, "the existence of other universes would in no way reduce the luck that we had had if, say, our universe's early symmetries had just chanced to break life-permittingly, and ... their existence could none the less reduce our amazement by providing a field enough to give a fair chance that life-permitting conditions would be being observed somewhere..." (Pg. 141-142)
He criticizes a teleological theistic argument: "Sympathetic though I am towards theistic explanations, this seems to me a pointless muddying of the waters. What is the use of a Principle which can mean just whatever you wish it to mean? How is anyone to understand anyone else if Strong Anthropic Principle talk can be EITHER observational evidence selection effect talk OR ELSE teleological/theistic talk OR ELSE some mixture of the two and perhaps other things as well?" (Pg. 145) He also notes, "any fine tuning is just an illusion of us Earthlings. Intelligent living organisms might often be very unlike those on Earth, and much less fussy in their requirements. They might stand in no need of chemistry, for example, or of planetary surfaces to inhabit." (Pg. 186)
He summarizes, "I need to say why the God hypothesis strikes me as non-silly, and even as every bit as plausible as the many-universes hypothesis." (Pg. 161) He admits that "The Problem of Evil is certainly strong enough to make theism an uncomfortable position." (Pg. 187) But he concludes, "fine tuning can only very implausibly be dismissed as an illusion of Earthlings. We thus seem forced towards the hypothesis of many and varied universes, or the God hypothesis." (Pg. 189) He adds, "My argument has been that the fine tuning is evidence, genuine evidence, of the following fact: that God is real, and/or there are many and varied universes." (Pg. 198) He reiterates in the book's final paragraph, "God is real and/or there exist many, very varied universes. Independently of all such evidence it is certainly hard to give a figure for the probability of that truth. Yet when we see the evidence, the conclusion to be reached can be plain enough." (Pg. 204)
This is a very thought-provoking discussion, that considers the “many universes”/multiverses argument in much greater detail than, say, a Richard Dawkins or Kenneth Miller does.
