But because someone is brilliant, especially in their field of study, it doesn't always make them right. One of those ultimate questions (they really list three) is "Why is there something rather than nothing?"1 Hawking and Mlodinow's answer is simply, "Because there is a law like gravity, the universe can and will create itself from nothing"2. They rely on the simple actions of gravity at a quantum level to balance the positive and negative energy of the universe and to create matter, time, and space.
I've written on some of the issues with quantum vacuums before, but there's a fundamental problem with this scenario, that may be easy to grasp. One cannot rely on a law to do anything by itself. The law of gravity cannot be the starting point because laws don't exist if there is nothing upon which the law governs. For a familiar comparison, let's look at traffic laws such as the speed limit.
Everyone who drives is familiar with a speed limit. The speed limit is a law set by a governing body in order to control the flow of traffic and keep the drivers safe in their vehicles. Some areas such as Germany's autobahn have no speed limit. But for a speed limit to mean anything, you have to have at least two other things: a vehicle and a road. If no road exists and there are no vehicles yet invented, limiting someone's driving to 65 miles per hour is not only foolish, it doesn't mean anything. How can you limit driving when no vehicles exist? And if there's no road to drive on, then there's no way to begin forward motion.
Imagine if you will creating laws as to how high and how fast the winged horse Pegasus can fly and you might see the problem. While your laws can be very specific and detailed, it doesn't matter because there is no wined horse for those laws to govern.
In The Grand Design, the authors use John Conway's Game of Life as their example of how a simple set of laws can lead to new patterns that weren't originally anticipated3. Hawking and Mlodinow extrapolates this into how all matter interacts and says we are the result of the same kind of new, surprising patterns. But the same problem applies. Conway's rules are just fine, but if there is no grid of squares and there are no lights to "live" or "die" as his rules define, then the game never gets off the ground. There's nothing to blink, so no new shapes appear. Of course, beyond even these problems, there's still one additional question that hasn't been answered. We know that Conway wrote the rules to his Game of Life, but who wrote the Law of Gravity?
It is unfortunate for the authors of The Grand Design that in their zeal to dismiss God from the creative process they assume that the Law of Gravity can answer all their problems. The question "why is there something rather than nothing" cannot be answered with gravity because gravity is a something. It's actually part of the question. Gravity and those objects that gravity affects are part of the something that needs explaining. Postulating gravity before the creation of anything else is simply trying to place a speed limit on a flying horse. The outcome produces no effect at all.

In most cheesy b-movies, we see the storyline play out predictably. The villain has made some advancement in pushing his agenda and the world starts to play by his rules. Therefore, in order to maintain his grip of power, our villain seeks to silence anyone who may disagree with him. He will discredit, disgrace or imprison anyone who offers up a contrary view to his plan. He seeks to be the only authority on all matters that he wants to control. In our look at science versus scientism, we also see a wrestling for power. There are those using science as one way of understanding the world, and there are those who say since science tells us about the natural world, that means that only science can tell us about anything. Scientism discounts all other forms of knowledge as either imperfect or not really knowledge at all.
Science owes a debt to philosophyAs we mentioned above, science has at its core the idea of observing interactions and critically examining their causes. Anyone beginning to study the subject of science is taught the scientific method, one of the primary ways scientists accomplish their task. Usually the method is divided into basic steps: a person has a question about some function of the natural world, he constructs a hypothesis, then tests that hypothesis with experiments, and analyzes the outcome. Lastly, he determines whether the original hypothesis is true and reports the results. This is a fundamental notion of what makes up our lab sciences. However, assumed in those steps is a lot of philosophy! Several philosophical principles must exist before the scientific method can even get started! Let's take a look at the components more closely and see where these assumptions lie.
Testing Hypotheses with ExperimentWhen scientists perform tests, one of the things they assume is a cause and effect relationship. If we are studying some effect, such as the attraction of magnets, we assume that there is a cause and effect relationship between the material of the magnets and their attraction. But we only make such an assumption because our past experience has shown that whenever material of this nature gets close to certain metals, a force is exerted between the two. How do we know that making such an assumption is warranted? Isn't one of the goals of science to eliminate assumptions and instead provide explanations for why functions happen? But then, aren't we starting with an assumption that cause and effect relationships are going to show us that? How do we know that the relationship we see isn't just a fluke of timing? Since it is only our experience that tells us about cause and effect, we are assuming our experience can tell us about the relation between the two, but we have no other reason to do so.
Realize, this line of doubt is not my own. Skeptic David Hume argued at great lengths to say that our experience may work for us, but that does not mean there is really a causal connection between two things, simply because one happens to come prior to the other.1 Basically, Hume asserts that science cannot test its own assumption about repeatability. Hume says trying to prove such things by experiment is really question-begging since you're using the very testing method that's in question! Therefore, in order to say that we know condition A produces effect B, we must rely on theories of what makes our knowledge justified. This again is the realm of philosophy. The scientist cannot scientifically prove that experience is a good indicator of what will happen in the future if the same conditions were to be produced; he relies on a philosophical framework to justify his assumptions.
Analyzing OutcomesOnce the scientist has performed experiments, he analyzes the outcome and draws conclusions as to whether it matches his hypothesis or not. But how can he be sure whether the results do indeed match his expectations? Philosophy comes into play here as well. In chapter 6 of this book, we took a moment and discussed the Three Standard Laws of Thought, also referred to as the Laws of Logic. We discovered that these laws were the main way that anyone compares and contrasts claims to see if they make sense or not. The Law of Identity states that a thing is equal to itself. So if the results of an experiment match the hypothesis, then the hypothesis can be considered valid in that instance.
We also learned from the Laws of Non-Contradiction and Excluded Middle that the result has to be either consistent with the hypotheses or inconsistent with the hypothesis.2 That means scientists use the Laws of Logic in analyzing their outcomes. Logic in all its forms is clearly identified as the only way a scientist can draw any conclusions that would continue to make sense.
Scientism dismisses philosophy as unnecessarySo, philosophy plays a crucial role in doing science well. It becomes the measuring stick on truth claims. But when our evil villain scientism enters the picture, he challenges this authority. While he uses philosophy, he sees anything other than what he defines as science as a threat and therefore dismisses it as unimportant or dead. Famous physicist Stephen Hawking, began his most recent work The Grand Design by doing just that. He writes:
"…philosophy is dead. Philosophy has not kept up with modern developments in science, particularly physics. Scientists have become the bearers of the torch of discovery in our quest for knowledge. The purpose of this book is to give the answers that are suggested by recent discoveries and theoretical advances."3Of course, such claims as "philosophy is dead" and "Scientists have become the bearers of the torch of discovery in our quest for knowledge" are highly problematic. For one thing both claims are themselves not scientific; there is no test that fits the scientific model one may perform and come up with those statements. No, saying "philosophy is dead" is making a philosophical statement itself; it's doing philosophy! The claim becomes self-refuting and can be dismissed. This is why Hawking's claim has been so widely criticized by philosophers of science, even those who are atheists!4
