Stephen Hawking and Leonard Mlodinow have written a must-read -book for anyone interested in the philosophical questions of cosmogony, or the origins of the universe. By implication anyone interested in the theology of creation should take a good look at it.
This book is in many ways a sequel to Hawking’s classic The Brief History of Time. The most important difference is that The Grand Design is both less technical and more philosophical than The Brief History of Time. On the upside it makes it readily accessible to a wider audience, but on the flipside the focus has shifted from topics they truly master towards issues where their expertise is less than impressive. This is an unfortunate combination, as the work may end up in hands of people, who don’t have the necessary expertise to assess the strengths and weaknesses of their argument.
Famously Hawking claims he has made an argument against the existence of God. Incidentally he hasn’t. Yet to understand what Christians really say about God, it is useful to understand the argument he makes, and why that does not say anything about the existence of God.
Theoretical Foundation
I confess that I share some of the high hopes of the authors and most scientists. First and foremost that there is a (more or less) single, elegant theory that explains pretty much everything in the existence. Reading the book one might forget, that we are not even near. Let’s recap what we don’t have:
- A clean quantum level theory of electromagnetism. QED and by extension the electroweak theory are not clean. We can do the renormalization calculations, but we don’t know why. This is not entirely unlike the situation with the ether in 1905: Einstein’s major breakthrough in that area was not coming up with new euations, but giving an explanation why certain known equations already known to work, work.
- Quantum theory of gravitation. In fact, we hardly have a decent theory of gravitation. In recent years the General Relativity Theory has been patched with less than elegant ways and it is generally considered to be in a severe crisis.
- “Theory of everything”, which combines the two above with QCD, (an accepted theory we do have and actively work on).
- String theory. Despite the name, this is not yet a “theory” (or accepted scientific model), but only a hypothesis. It’s under heavy work and experimentation right now, and the odds are that it will be accepted as a model sooner or later.
- M-theory. This is more or less handwavium and based on speculation – at best speculating on the above theories.
Nevertheless, I share their optimism that we will find such theories. Especially the M-theory seems tempting. I admit I would like it – or some even more elegant theory to describe the uni(/multi)verse accurately. If only I knew that the M-theory was correct, it would rank fairly high on my ”Praise the LORD for…” -list. But as it is, I don’t dare to praise Him for what He might not have done.
Dilemma of Philosophy
As stated, unlike the Brief History of Time, this book is first and foremost philosophical. Ironically on the first page they write: “Traditionally these questions are dealt with philosophy, but philosophy is dead.” This statement is very telling of their own understanding of their very own subject matter. It also explains why the presented argument is at times weak. For example they pretty much take granted that the laws of physics really are immutable always and everywhere. They also dismiss the inexplicable fact that we are able to describe the universe in mathematical terms in the first place.
However they do have a point. They are just saying that many contemporary philosophers don’t know enough physics to talk about things related to it – like metaphysics. This is often true. However, when they claim that this stand has now been taken by scientists, they essentially fall into the same trap: scientists rarely know enough about metaphysics to say anything about it. The truth is of course that scientists and philosophers have often been the same people, Leibniz and Newton being great examples of this. But one should know both sides when talking about a matter that spans over the sides.
Ironically The Grand Design is a proof that some scientists understand too little philosophy to write about it. The authors are mostly writing philosophy backed by science, but aren’t clear when they move on pure speculation. Further their argument is at times blurred. The title of the book is The Grand Design, yet they seem to try to prove that there is no design, merely order- until in the acknowledgment they state that the universe has a design (but are quiet about its possible designer). They seem to be on some kind of odyssey to prove that God does not exist, but while surrounded with facts, the argument is rather rhetorical than actually based on those facts. For instance, they present a very naïve history of science with an agenda concerning its relationship with religion. Agenda that does not stand historical analysis. All in all, while they do good job in presenting their hard knowledge about scientific theories and their implications, they are blatantly ignorant about the questions of philosophy and religion and fail to compile an argument meaningful even to refute.
The Famous Argument
In simple terms, their argument against the existence of God goes as follows: M-theory allows a vast number of universes, each with different fine-tuning “laws”, to emerge without any external cause. One of them is ours, and obviously habitable. Ergo, God is not needed to create the universe.
This argument is philosophically motivated. The universe seems to be fine-tuned in many ways to allow us to be here in the first place. One might be tempted to use this fine-tuning as an argument that it had to be done by God, therefore God does exist. To such people the book says: No, you don’t need God to do the fine-tuning. So their argument doesn’t actually refute the existence of God, but a fundamentally flawed attempt to prove the existence of God. Which I, as a Christian theist, am thankful of.
To me, creating just a universe big enough to support human life seems a little is not that awesome. After all, He has created the infinity as well. Surely He could do more, something great and elegant. To have just one universe fine-tuned just for us? That’s not too elegant. Why not have it fine-tuned for us as an obvious and incidental by-product of something great and elegant? Wait… the M-theory would be a great candidate just for that…
On a more serious note, the Grand Design argument against God fails on two sides. One one hand, it does not state what kind of “god” are they talking about. It’s not mentioned even in the glossary. Based on their treatment of the topic, it is however clear that they are not talking about the I-AM the Judeo-Christian tradition is aware of. And since God with a capital G is a word commonly used to address Him, I can only conclude that out of their ignorance of facts they have simply misspelled the word.
On the other hand they do make an honest attempt to give a final kick against the “god of gaps”, a supernatural element added to explain things the science still has to figure out. Many have likened GOG and God, though they have nothing – and everything – to do with each other. The problem with GOG is that as science advances, it and pushes him further. The Grand Design pushes GOG out of yet another gap – fine-tuning – and the authors seem to believe that this is the last one. But in reality the GOG just falls into the next gap: Why is there the M-theory rather than something else? (Won’t these gaps never end?)
A Word about God
Just like the authors never really defined what kind of deity they were actually after, I should state here briefly what is God like and why His existence remains unchallenged by The Grand Design.
To begin with, His name is I-AM. He does not need proof or even evidence to exist, that He can do without any help. Further, he created everything – and assuming M-theory exists, that is part of His creation. Claim that universe came out spontaneously, makes sense – that is a way He may have done it. But He Himself did not come about in any way. Universe may have borrowed its existence from unstability, but I-AM exists with no need for such provisions. When we talk about God, it is this self-existing transcendent creator we are talking about.
But there’s more. I said that He has everything to do with god of gaps. While GOG is our naive idea “god did it”, God actually did do it. He not only made the laws of nature, but he actively upholds them. Should He stop, the laws would not break down, but the Creation would seem to exist. We are here only because He, who is, wants it that way.
So it is clear that God is not just some deistic creator who kicked the universe into motion and went for coffee, but actively involved with the creation. Since He is the active Creator of everything, He is free to deviate from the laws He has made whenever He wishes for. This would be a definition of a miracle. But He has done more than mere Creation and miracles: He entered into the creation Himself.
This is a thing that sets Christianity clearly apart from other religions. Creator, who belongs to another ontological category than everything else we know, became one of us, into same ontological level as we are. It’s not just about intervening the laws of nature, it is about intervening the nature itself. The rest, as they say, is the history of salvation.
His primary concern is not if people believe He exists or not. He wants our intimacy with Him. When He gets that from someone, that person will of course positively know He exists. On the other hand, if someone does not have Spirit of God living in him, it makes little difference if that person believes He exists.
Therefore we should not waste time trying to prove God exists. He is fully capable of doing that Himself. In fact, if we do that we might end up thinking about God the way He is not, and thus our intimacy would suffer. The proper order is to seek first God, and let Him prove Himself.
There’s no reason to assume, that study of nature would prove the existence of God. Actually, one can argue the opposite. While we can expect that the nature will not disprove His existence – so far so good – we should also expect that it will not lead us to God. He does not want science to be a way to Him. He wants to be Himself the way to Him. That is intimacy.
Conclusion
Read the book. It’s well written and you’ll have fun – one way or another. If you are interested in physics, read the Brief History of Time first. This adds to that. If you are not into physics, just read the Grand Design. If you don’t believe in God, don’t expect to get a silver bullet to prove your point. If you do believe in God, it might relief you from some of the wrong reasons to believe in His existence though, which is a good thing.
Nothing is more dangerous than one good idea. For this reason it’s often more useful to read books by people who disagree with you. Hawking and Mlodinow have several ideas worth getting to know, some of which are good. Read the book. Who knows, you might learn something, or at least get something to think about …and that is a good thing for any man.
