Mind of God: The Scientific Basis for a Rational World
By Paul Davies

Taking Science on Faith

SCIENCE, we are repeatedly told, is the most reliable form of knowledge about the world because it is based on testable hypotheses. Religion, by contrast, is based on faith. The term “doubting Thomas” well illustrates the difference. In science, a healthy skepticism is a professional necessity, whereas in religion, having belief without evidence is regarded as a virtue.

The problem with this neat separation into “non-overlapping magisteria,” as Stephen Jay Gould described science and religion, is that science has its own faith-based belief system. All science proceeds on the assumption that nature is ordered in a rational and intelligible way. You couldn’t be a scientist if you thought the universe was a meaningless jumble of odds and ends haphazardly juxtaposed. When physicists probe to a deeper level of subatomic structure, or astronomers extend the reach of their instruments, they expect to encounter additional elegant mathematical order. And so far this faith has been justified.

The most refined expression of the rational intelligibility of the cosmos is found in the laws of physics, the fundamental rules on which nature runs. The laws of gravitation and electromagnetism, the laws that regulate the world within the atom, the laws of motion — all are expressed as tidy mathematical relationships. But where do these laws come from? And why do they have the form that they do?

When I was a student, the laws of physics were regarded as completely off limits. The job of the scientist, we were told, is to discover the laws and apply them, not inquire into their provenance. The laws were treated as “given” — imprinted on the universe like a maker’s mark at the moment of cosmic birth — and fixed forevermore. Therefore, to be a scientist, you had to have faith that the universe is governed by dependable, immutable, absolute, universal, mathematical laws of an unspecified origin. You’ve got to believe that these laws won’t fail, that we won’t wake up tomorrow to find heat flowing from cold to hot, or the speed of light changing by the hour.

Over the years I have often asked my physicist colleagues why the laws of physics are what they are. The answers vary from “that’s not a scientific question” to “nobody knows.” The favorite reply is, “There is no reason they are what they are — they just are.” The idea that the laws exist reasonlessly is deeply anti-rational. After all, the very essence of a scientific explanation of some phenomenon is that the world is ordered logically and that there are reasons things are as they are. If one traces these reasons all the way down to the bedrock of reality — the laws of physics — only to find that reason then deserts us, it makes a mockery of science.

Can the mighty edifice of physical order we perceive in the world about us ultimately be rooted in reasonless absurdity? If so, then nature is a fiendishly clever bit of trickery: meaninglessness and absurdity somehow masquerading as ingenious order and rationality.

Although scientists have long had an inclination to shrug aside such questions concerning the source of the laws of physics, the mood has now shifted considerably. Part of the reason is the growing acceptance that the emergence of life in the universe, and hence the existence of observers like ourselves, depends rather sensitively on the form of the laws. If the laws of physics were just any old ragbag of rules, life would almost certainly not exist.

A second reason that the laws of physics have now been brought within the scope of scientific inquiry is the realization that what we long regarded as absolute and universal laws might not be truly fundamental at all, but more like local bylaws. They could vary from place to place on a mega-cosmic scale. A God’s-eye view might reveal a vast patchwork quilt of universes, each with its own distinctive set of bylaws. In this “multiverse,” life will arise only in those patches with bio-friendly bylaws, so it is no surprise that we find ourselves in a Goldilocks universe — one that is just right for life. We have selected it by our very existence.

The multiverse theory is increasingly popular, but it doesn’t so much explain the laws of physics as dodge the whole issue. There has to be a physical mechanism to make all those universes and bestow bylaws on them. This process will require its own laws, or meta-laws. Where do they come from? The problem has simply been shifted up a level from the laws of the universe to the meta-laws of the multiverse.

Clearly, then, both religion and science are founded on faith — namely, on belief in the existence of something outside the universe, like an unexplained God or an unexplained set of physical laws, maybe even a huge ensemble of unseen universes, too. For that reason, both monotheistic religion and orthodox science fail to provide a complete account of physical existence.

This shared failing is no surprise, because the very notion of physical law is a theological one in the first place, a fact that makes many scientists squirm. Isaac Newton first got the idea of absolute, universal, perfect, immutable laws from the Christian doctrine that God created the world and ordered it in a rational way. Christians envisage God as upholding the natural order from beyond the universe, while physicists think of their laws as inhabiting an abstract transcendent realm of perfect mathematical relationships.

And just as Christians claim that the world depends utterly on God for its existence, while the converse is not the case, so physicists declare a similar asymmetry: the universe is governed by eternal laws (or meta-laws), but the laws are completely impervious to what happens in the universe.

It seems to me there is no hope of ever explaining why the physical universe is as it is so long as we are fixated on immutable laws or meta-laws that exist reasonlessly or are imposed by divine providence. The alternative is to regard the laws of physics and the universe they govern as part and parcel of a unitary system, and to be incorporated together within a common explanatory scheme.

In other words, the laws should have an explanation from within the universe and not involve appealing to an external agency. The specifics of that explanation are a matter for future research. But until science comes up with a testable theory of the laws of the universe, its claim to be free of faith is manifestly bogus.

Paul Davies is theoretical physicist, cosmologist, and astrobiologist. He currently holds the position of Professor of Natural Philosophy in the Australian Centre for Astrobiology at Macquarie University.

"whereas in religion, having belief without evidence is regarded as a virtue."

I dispute this statement.  Belief is never without some kind of evidence--generally testimony of some sort.  Thomas was rebuked for relying solely on his own senses for evidence.

"Clearly, then, both religion and science are founded on faith"

Science is founded on metaphysical assumptions.  It progresses by experimentation, testimony from other scientists, and theorizing.

The entire argument he puts forth is based on the claim that we assume the order of the universe, or specifically we assume the external objective reality we are experiencing. That is garbage. We have every good reason to base the objectivity off the consistency that we find in our shared experiences. We didn't just say "the universe is ordered, lets test some stuff." It was through the experimentation and testing, etc. that we discover the universe is well ordered. That isn't mystical, it's how any relation is going to organize itself. If relations were chaotic, then we wouldn't have things functioning in any systematic way that is required for a process to be a process. We take a process view of the universe. The extension of our basic understandings to the subatomic world, etc. isn't just assuming there's going to be elegance there. In fact, quantum mechanics is not that elegant, and quite counter-intuitive. The mathematics works out, but wow, that's another one of those relational things just like I mentioned. No one is going to dispute that these relations are ordered, but that's almost tautological. It isn't mystical or proof of design. There need be no conscious or thoughtful entity behind every process and relation in the universe, so why posit one at the back of all of it?! Any further discover is elegant in terms of what we have already discovered because we are certain about the consistency of what we know now. But at the fringe of science, things are not so elegant, and part of that is simply due to our ignorance. What is expected is that if there is a fundamental relationship pertaining to how things are interacting, then it's going to be, as what seemed tautological all along, that there's going to be some elegance behind it.

@darkwolfofvoid - "We have every good reason to base the objectivity off the consistency that we find in our shared experiences."

What do you mean by "shared experiences?"

"We didn't just say "the universe is ordered, lets test some stuff.""

Actually, we did.  See Whitehead or Pearcy and Thaxton.

"In fact, quantum mechanics is not that elegant"

???  I found it to be very elegant.

"There need be no conscious or thoughtful entity behind every process and relation in the universe, so why posit one at the back of all of it?!"

Your restatement of Davies argument is lacking an important element.  Let me rephrase your restatement to make the issue more plain: "There need be no conscious or thoughtful entity behind every process and relation in the universe which are governed by fixed and immutable laws, so why posit a lawgiver at the back of all of it?!"

The answer seems to me to involve our humanity.  We form laws; formation of laws requires thought and understanding.  Discovery of natural laws by scientists likewise requires thought and understanding.  Natural laws are more complex in their functioning than our man-made laws; their formation would require greater thought and understanding than we possess.

"??? I found it to be very elegant."

If you find random probability elegant. Quantum entanglement? puh.

I agree with darkwolfofvoid, our observations are indeed based upon consistent results. Remember that the scientific community is not one of speedy conclusions. It takes many years for scientists to formulate their theories (based upon their observations, not faith) and it takes many more for them to submit their findings to the community as a whole, where it is rigorously scrutinized, and eventually (if they're lucky) become accepted.

Goodgreypoet makes the process sound like a town hall meeting on a Wednesday night.

soccerdad:

[I dispute this statement.  Belief is never without some kind of evidence--generally testimony of some sort.]

Agreed. And I think Davies disputes this statement too, which is why he precedes it with the phrase "we are told" to indicate that this isn't his stance. I think Davies just wants to point out that both science and religion rest on alot of unproven assumptions that require a "leap of faith" to accept and that the hitherto "neat seperation" between the two is illusory. Science doesn't rest on evidence while religion rests completely on faith. They both have degrees of evidence in their favor, but they both require that we first accept their initial assumptions on faith.

Wolf:

[It was through the experimentation and testing, etc. that we discover the universe is well ordered.]

Agreed. But I think the more important question that Davies is trying to get at here is, from whence comes the order? From whence comes the natural laws that we all just accept as axiomatic? To account for them we must either speculate the existence of a lawgiver (i.e. where there are laws there is a lawgiver), or we must speculate that the natural laws are eternal and have always existed. But we have no proof of either, so both require a "leap of faith" if you will.

[There need be no conscious or thoughtful entity behind every process and relation in the universe, so why posit one at the back of all of it?!]

Well, its either that or just assume that the natural laws are eternal and have alway existed. What is the evidence for that? All the evidence to date suggests that the natural laws came into existence at the moment of the Big Bang. Which is why Davies says that whatever created the universe must have both preceded and transcended it. Theists argue that this was a designer while most atheists argue that the universe itself is eternal and doesn't need a reason for existing...it just always has. But as Davies says: "The idea that the laws exist reasonlessly is deeply anti-rational. After all, the very essence of a scientific explanation of some phenomenon is that...there are reasons things are as they are." Just saying that the natural laws exist without reason is anti-rational and anti-scientific because science always seeks to discover cause-effect relationships. It doesn't throw its hands up and say: "Well thats just the way it is!"

@comenowtisI - "If you find random probability elegant."

Just choose a large sample and the probabilities sort themselves out among the quantized states.  I found this quite elegant.

"Quantum entanglement?"

Magic!  Pay no attention to the man behind the curtain.

"I agree with darkwolfofvoid, our observations are indeed based upon consistent results."

But philosophically, we presupposed an ordered universe in Christian Europe due to theological presuppositions.  This ordered universe meant that there were fixed laws (as oppose to randomly-varying properties which some religions believe).  This gave science a basis for its method.  There's no denying that fact.

"It takes many years for scientists to formulate their theories (based upon their observations, not faith) and it takes many more for them to submit their findings to the community as a whole, where it is rigorously scrutinized, and eventually (if they're lucky) become accepted."

Surely, it can take eons, like a meeting of the Ents.  Sometimes theories are accepted and rejected several times.  A lot of times it ends up being an argument between philosophies as Nancy Pearcey pointed out.

"Goodgreypoet makes the process sound like a town hall meeting on a Wednesday night."

Well, sometimes those meetings may seem like they take eons.    Old business has a way of coming up at those town hall meetings when people don't like the original decision.  Tenacity can be a virtue if it is applied with good reason.

I'd like to ask Paul Davies what the laws of astrobiology are.

@soccerdadforlife - 

Those shared experiences we all have that help us shape our objective reality. The couple people you mention do not constitute the universe of "we." That is not how science operates. I am sure you've listened to, or watched, Dawkin's speech about the queerness of the quantum world (I do believe it is on ted dot com). The only elegance in it comes from the limited theories we have. It is still quite queer. As for your restating my argument, the point has nothing to do about law making. The natural laws are in no way analogous to man-made laws. They're not even laws in that sense. That comparison is horrible!

@GOODGREYPOET - 

The order comes part in parcel with what constitutes the universe. Whether there is some intelligence or natural phenomena behind that may be something we will never know, but you seem to not understand what an axiom is. These "laws" are not primitive terms of some system we just take for granted to define everything else. We have proven the confidence in these things we have discovered. We don't look at them as having been caused nor eternal because that's like saying "was electro-magnitism created or just existed forever?" That is nonsensical. We have proven that electro-magnitism is the by-product of complex interactions with subatomic particles as shown by the Standard Model. If the ultimate concern is "what started or created the universe?" then that is not a question of physics since our tools to measure are governed by the universe we have to use them in. If we could transcend the universe, then it would not be a problem, possibly, to evaluate the universe with transcended tools. Nevertheless, there is no reason to suppose a creator or such since what could have constituted the Big Bang could just as well been a natural phenomena itself, or "thought-less" if you will. We can't say. Our universe could be the result of a transcended elephant fart for all we know. It bears very little weight on what we're doing here in our trivial little existence.

Well, his understanding of it is probably at the pop-science level.    He's out of field.

"The only elegance in it comes from the limited theories we have. It is still quite queer."

Counter-intuitive maybe, but mathematically elegant.  For those who appreciate mathematics, there is a beauty in it.

"The natural laws are in no way analogous to man-made laws. They're not even laws in that sense. That comparison is horrible!"

Although you may not like it, the concept of natural law that we can understand forms the basis of modern science which itself came out of the Christian worldview.  This is a simple matter of history.

That sounds like a skewed history! Natural does does not form the basis of modern science. In fact, the history of science shows God only showed up to fill the Gaps. Every scientist explained nature without God, and only introduced Him to solve the problems of their limited theories. This is why the God of the Gaps is shrinking these days.

And how do you suppose quantum mechanics is mathematically elegant??

You are weak in history, grasshopper.

"I consider The Soul of Science [by Nancy Pearcey] to be a most significant book which, in our scientific age, should be required reading for all thinking Christians and all practicing scientists. The authors demonstrate how the flowering of modern science depended upon the Judeo-Christian worldview of the existence of a real physical contingent universe, created and held in being by an omnipotent personal God, with man having the capabilities of rationality and creativity, and thus being capable of investigating it. Pearcey and Thaxton make excellent use of analogies to elucidate difficult concepts, and the clarity of their explanations for the nonspecialist, for example, of Einstein's relativity theories or of the informational content of DNA and its consequences for theories of prebiotic evolution, are quite exceptional, alone making the volume worth purchasing." --Dr. David Shotton, Lecturer in Cell Biology, Department of Zoology, University of Oxford

In addition, I recommend reading Rose-Mary Sargent's book about Robert Boyle, who founded the Royal Society; Boyle's practice of and influence on the experimental method was foundational to experimental science.  Boyle was able to attract several important assistants, including Robert Hooke, to work with him.

I found both books to be excellent reads.

"And how do you suppose quantum mechanics is mathematically elegant??"

@darkwolfofvoid - By the way, the knucklehead who thought my understanding of amino acid chemistry was lacking has apparently forgotten that all amino acids have an acidic character due to the carboxylic acid group, which means that a reducing environment such as in Stanley Miller's experiment will play havoc with their yields.  (Amino acids also have a basic character due to the amine group.  The R-group also plays a major role in amino acid chemistry and may be acidic, neutral, or basic in character.)  As I recall, Miller got yields in the low single-digit percentages in his trap which was well away from his reducing environment in the spark chamber.  Mixed in with the amino acids was a substance described as "tar." These things collected on the sides of the tubing and didn't remain in solution long.

How about Astronomy? I do believe astronomy dates back far beyond the times of Christianity. Babylon, ancient China, work by Aristotle. Was it not the Christian church that actually opposed the theories of growing science? Poor Galileo and Copernicus. If not for their defiance of the church's understanding of nature, modern astronomy would be very far behind indeed!

Good questions.

Ancient astronomy was not modern science.  Modern science didn't really begin until Robert Boyle founded the Royal Society.  Boyle founded English science squarely on a philosophy of science which relied on scriptural principles.  He came up with the Book of Nature idea.

Galileo's troubles were caused by his fellow astronomers, none of whom believed in a ptolemaic system.  They instigated accusations against Galileo with the church--the church didn't go hunting astronomical heresies on its own.  Just some early toxic politics in science.  We have plenty of that today as well.

I'm unaware of any problems Copernicus had with the church.  Perhaps you will enlighten me.

To dismiss ancient science as having an influence on modern science is silly. Scientists still observe and theorize and hypothesize just the way they have always been. Science has always been there as a tool to help explain the world around us. Perhaps you could be so kind as to distinguish why ancient science is irrelevant to modern science for me?

Also, would you mind telling me where you found the information about the toxic politics in science? If perhaps you are referring to the Jesuits instigating his arrest, you must remember that they are still part of the church.

As for Copernicus, he certainly did not feel the same sting that Galileo felt, but there was controversy and he was attacked by two in particular: Giovanni Maria Tolosani and Bartolomeo Spina, both members of the church.

"To dismiss ancient science as having an influence on modern science is silly."

I agree, but I didn't do that.

"Scientists still observe and theorize and hypothesize just the way they have always been."

Boyle's experimental philosophy refined the experimental procedures for modern science and introduced several new concepts, including forming a society of scientists which produced a regular journal and experimental verification by other scientists.

"Also, would you mind telling me where you found the information about the toxic politics in science?"

I am preparing a post about that.  My sources are eclectic.

"If perhaps you are referring to the Jesuits instigating his arrest, you must remember that they are still part of the church."

The point is that they were his fellow scientists.  Their intrigue was due to jealousy and anger over Galileo's caustic communication, not due to theological issues.

More info on Copernicus's major work:

"After that, De revolutionibus was placed on the Index of Forbidden Books along with two less important works (but none of Galileo's, at that time). It was not formally banned but merely withdrawn from circulation pending "corrections" which would clarify the status of the theory as hypothesis (nine sentences, by which the heliocentric system was represented as certain, had to be either omitted or changed). Such corrections were prepared by Francesco Ingoli and others, and were formally approved in 1620; the reading of the book was then allowed.[3] But the book was never reprinted with these changes, and was available in Catholic jurisdictions only by special request of suitably qualified scholars.[citation needed] It remained on the Index until 1758, when Pope Benedict XIV (1740-58) removed the uncorrected book from his revised Index.[" http://en.wikipedia.org/wiki/De_revolutionibus_orbium_coelestium

ryc:  thanks and congrats to you too - I know how exciting this first baby is.  To answer your question, yes and no.  With each of my pregnancies I have been equally excited and in awe, I find myself smiling for no reason other than knowing there's a little person growing inside of me - it just doesn't get much cooler than that - but with your first one you really have no idea what to expect and when it's something you've planned for and waited for, the anticipation and excitement are different, not better, just different.  My husband seems less excited this time around (#3), though he's really happy about it, I think he just knows what to expect and so it's less dramatic for him than the very first time.  Plus, though you will love all your children equally (perhaps differently, but still equally) there is nothing quite like the first child - it's the one time you are able to dole out all your attention on one child, you have more time and energy to focus on them and don't have to think about getting your other children to school or dance or soccer practice - that kind of thing.  But pregnancy and babies, growing toddlers, and beginning kindergartners - it never loses it's magic or appeal.  From reading Kimber's site and listening to her talk about you and you guys life together I have no doubt that you will be great parents - enjoy the adventure!

Nah, David Hume already pointed that problem out centuries ago, and probably many others before him.  According to the no-God theory, sure, existence of perceived laws cannot be explained, but one is still open to the possibility that they may change since there exists no explanation for them.  It would just major majorly suck if they did!

Only God then makes sense of the laws.  Making sense of God is a whole other issue of course. ;)

Fabulous article.  I've stopped by here several times, but never really read this all the way through.  I like his argument and his reasoning is sound.  Of all the things we take on faith, I think that many assume that science stands on it's own two feet, but Mr. Davies argues well that this is not the case.  Faith seems to be evident, to some degree, in all things, and for me that is reassuring.
