Why Believing in Miracles is Not Illogical



When Christians believe in miracles, are they being irrational? A recent Pew Research article entitled "Why America's 'nones' left religion behind" held this interesting quote:
About half of current religious "nones" who were raised in a religion (49%) indicate that a lack of belief led them to move away from religion. This includes many respondents who mention "science" as the reason they do not believe in religious teachings, including one who said "I'm a scientist now, and I don't believe in miracles." Others reference "common sense," "logic" or a "lack of evidence" – or simply say they do not believe in God.1
There's a whole lot in that paragraph to unpack. However, the claim that faith is somehow against logic caught my eye. Just how would Christianity be illogical? One claim made by atheists is that believing in miracle accounts like those presented in the Bible is itself illogical.

The charge that believing in miracles is illogical as a long history, and most will point to David Hume's famous essay "On Miracles" in his An Enquiry Concerning Human Understanding. There, he makes this charge:
A miracle is a violation of the laws of nature. There must, therefore, be a uniform experience against every miraculous event, otherwise the event would not merit that appellation. And as a uniform experience amounts to a proof, there is here a direct and full proof, from the nature of the fact, against the existence of any miracle.2

What is a Miracle?

I think Hume makes two mistakes in his assertion above. First, his definition of a miracle, while widely repeated, is simply wrong. It isn't what Christians believe. Miracles are not violations of the laws of nature, but God's direct interaction to suspend his natural laws, which is a big difference.

To clarify, one must understand what we mean when we use the term natural law to begin with. A natural law is simply the way certain portions of the material world work. For example, any two objects will be attracted to one another and that attraction multiplies based on how much mass the objects have and is inversely proportionate to how far away they are. The bigger the objects and the closer they are, the greater the attraction. This is what is known as the law of gravity. If I drop a rock, it will fall towards the earth, because the mass of the earth is so big it pulls on the rock more than the rock pulls on it.

To violate the law of gravity, one should see a rock not fall to the earth even though there is nothing impeding its fall. A violation means all things were the same, but the outcome is different. But that isn't what's happening in a miracle, because with miracles we have an additional actor: God. It isn't the case that all things are the same.

This is why miracles shouldn't be considered a violation of a natural law, but God suspending natural law by his power. God is in some way defeating the natural outcome by inserting himself into the mix, just as I can defeat the natural outcome of the falling rock by sticking out my hand and catching it before it hits the ground. Philosopher Richard Purtill agrees. He defines a miracle as "an event in which God temporarily makes an exception to the natural order of things."3 

Given that understanding of what a miracle is, we can create the following argument:

P1: Miracles are not violations of nature's law, but suspensions of nature's laws.
P2: If God created nature's laws, God can suspend nature's laws.
P3: God created nature's laws.

C1: Therefore, God can suspend nature's laws.
C2: Therefore, God can perform miracles.
So, miracles are not in themselves illogical if God exists and he created the universe with its natural laws. For miracles to be illogical, the premise that such a God exists must be shown to be false. That means those who reject God because of the illogic of miracles are actually begging the question! They are assuming God doesn't exist to prove God doesn't exist. That's the truly illogical position to take.

Miracles Don't Contradict The Laws of Nature



Miracles are a big topic. The skeptics dismiss then, faithful believe in them, many pray for them to occur in their lives. However, a lot of atheists seem to mis-define them. I was talking with an atheist friend who stated "By definition, a miracle violates natural law." By violate, I think he means "contradict." He isn't alone in that definition. The 18th century Scottish skeptic David Hume also sought to dismiss any claim of miracles as unreasonable in his Philosophical Essays Concerning Human Understanding. He wrote:
A miracle is a violation of the laws of nature. There must, therefore, be a uniform experience against every miraculous event, otherwise the event would not merit that appellation. And as a uniform experience amounts to a proof, there is here a direct and full proof, from the nature of the fact, against the existence of any miracle.1
That definition has become popular with hose seeking to debunk any miracle claims. However, Hume was wrong. A miracles doesn't violate the laws of nature, it suspends them. That's a big difference. The suspension of a law isn't a violation; it's simply an intervention. If you were in your kitchen and saw an egg rolling off the counter, you would know that gravity will pull that egg to the ground. However, you can intervene and catch the egg to keep it from falling to the ground. You've exercised your power to stop what would by the laws of nature produce a mess. So if God can intervene in our world to keep a man from falling into the sea, allowing him to walk on water, we would see it as a miracle.

Some may object that the example above isn't fair. After all, catching an egg is just as natural as letting it fall. While this is true, the concept of intervention holds if the one intervening is not limited to the natural world. As an example, think about computer programs. If you are a programmer, you write a computer program to perform certain tasks in a certain order. Perhaps you are creating a shopping site and you wish customers to enter their names, address, credit card number, expiration, and card verification value (that little three digit number on the back of the card) before you process the sale.

You've created these rules and any time the customer checks out, they will always follow this pattern. But, as the programmer you sometimes have to test certain portions of your code. When you are running sample transactions over and over, it becomes too time consuming to enter all that information each time. Yet, because you are the programmer, you can choose to initiate your code at any point. You can write a script that will bypass all these requirements and process a transaction with no data whatsoever. Then, when you are satisfied with the code, you remove the test script and allow the page to function as it normally does.

"Back-Door Code" to the Universe

There is nothing illogical about this kind of suspension of the computer program's rules. They weren't violated, they were bypassed. Similarly, God wrote the rules for how the world works. Therefore, he can write "back-door" code to bypass the normal systems and it is perfectly appropriate to do so. Just as a computer programmer can still not violate the operations of his programming language but suspend the laws of submit a blank transaction, so God can work within his own abilities and suspend the laws of nature to achieve his desired result.

Philosopher Richard Purtill defines a miracle as "an event in which God temporarily makes an exception to the natural order of things."2 That's a pretty good definition.
  1. A miracle is a temporary (the natural course of order will resume upon the miracle's completion)
  2. It is an exception to the ordinary course of nature
  3. It requires us to know what the limits of "ordinary course of nature" are.
A miracle is not God contradicting Himself or His laws.

Rights Don't Come From Nature

Last week I began to examine how the rights of all people, as expressed in the Declaration of Independence, must be rooted in God. I looked at the concept of rights being bestowed by governments or by the common consent of the people within a society and found both wanting. Today, I'd like to look at the possibility that rights come from our natural existence rather than a divine creator.


In such discussions, it becomes important to clarify our terms. We must understand both the concept of rights and the concept of nature to which I'm referring. For rights, I've covered that somewhat in my last post. However, to reiterate I quote from the Stanford Encyclopedia of Philosophy which has a fairly good summation on the universality of human rights:
Human rights are universal All living humans—or perhaps all living persons—have human rights. One does not have to be a particular kind of person or a member of some specific nation or religion to have human rights. Included in the idea of universality is some conception of independent existence. People have human rights independently of whether they are found in the practices, morality, or law of their country or culture. This idea of universality needs several qualifications, however. First, some rights, such as the right to vote, are held only by adult citizens or residents and apply only to voting in one's own country. Second, the human right to freedom of movement may be taken away temporarily from a person who is convicted of committing a serious crime. And third, some human rights treaties focus on the rights of vulnerable groups such as minorities, women, indigenous peoples, and children.1
When I am discussing nature as the supplier of rights, I'm pointing to the idea that the natural world is all there is; we exist only because of the physical laws of the universe and perhaps some fortuitous chemical combinations and mutations that ultimately resulted in human beings. This concept is well known as metaphysical naturalism or materialism and has many adherents within the scientific community. Those who ascribe to this worldview and still seek to maintain that human rights are real would seek to ground those rights in the natural world instead of God.

But this is where the problem lies. Nature cannot bestow rights at all. The natural world is what we observe. It has materials and laws, such as the laws of gravity or the laws of physics, which describe how certain materials interact. If one drops a cannonball off a ledge, it will fall at a certain acceleration. If one combines an acid and a base, the result will be salt and water (and possibly a big explosion!)

But laws such as these are merely descriptors. They tell what will happen if certain conditions are met. Human rights are something different. For while all living persons have rights, it is not the case that all living persons will be able to exercise those rights. People are denied their rights by dictators or repressive regimes all the time.

That means that nature only provides an "is" description of the way things are while someone being allowed to exercise his or her rights fall into an "ought" description. Rights are things based in the intrinsic value of being human. Nature doesn't care about value, it is indifferent to whether creatures live or die. Species have gone extinct since the dawn of time, even without man's help. Sickness can wipe out entire nations. That is simply how things are. This means that rights are fundamentally different from nature and the description of what is. An "ought" can only be derived from a moral law, which must come from a transcendent mind.

Scottish skeptic David Hume is famous for explaining the is-versus-ought distinction. Hume explains that simply because something is the case, it does not mean that such ought to be. In Book III, Part 1, Section 1 of A Treatise of Human Nature he expounds on this, writing that "moral good and evil belong only to the actions of the mind"2 and therefore cannot be reasonably derived from only external circumstances. He continues, "All beings in the universe, considered in themselves, appear entirely loose and independent of each other. It is only by experience we learn their influence and connection; and this influence we ought never to extend beyond experience… But to choose an instance, still more resembling; I would fain ask any one, why incest in the human species is criminal, and why the very same action, and the same relations in animals have not the smallest moral turpitude and deformity?"3

As Hume has shown, there is no way to connect the "is" of the natural world to the "ought" of human rights. Even if you argue that such rights help human beings survive, who is to say that humans shouldn't go extinct? Nature doesn't care. Therefore, as rights are part of those "actions of the mind" it requires a mind to ground them, and since human rights are universal, that mind must not only transcend all of humanity, but be able to establish value for all of humanity. The Creator of humanity would fill both necessary conditions for universal human rights to exist. Therefore, the Founding Fathers had it right: it is only in our Creator that we are endowed with certain unalienable rights.  No other explanation makes sense.

Scientism rejects philosophy as a form of knowledge

Yesterday, I began a series called "Science versus its Evil Twin: Scientism:." I had written that there are five major clues that distinguish the pursuit of science, and I examined the first in yesterday's post. Today, I'd like to look at the first part of Clue #2 – Scientism rejects other forms of knowledge.


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 philosophy

As 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 Experiment

When 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 Outcomes

Once 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 unnecessary

So, 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."3
Of 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

But you must confess that the inference is not intuitive, neither is it demonstrative. Of what nature is it, then? To say it is experimental, is begging the question. For all inferences from experience suppose, as their foundation, that the future will resemble the past, and that similar powers will be conjoined with similar sensible qualities. If there be any suspicion that the course of nature may change, and that the past may be no rule for the future. All experience becomes useless, and can give rise to no inference or conclusion.

Why Appeal to the Existence of Evil?

A fairly constant objection to God's existence is also one of the oldest objections.  It centers on the existence of evil and how any all-good, all-knowing God would allow any evil to exist in His creation. It was first widely voiced by the ancient Greek philosopher Epicurus who asked:

"Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing. Then Whence Cometh Evil?
Is he neither able nor willing? Then why call him God?"

Skeptic David Hume repackaged the riddle and it's been highly popular with skeptics and atheist ever since.

The problem with this objection is that it assumes there are only two factors to consider. But if we add a third proposition, say that God may allow evil to exist temporarily for a higher purpose, then the argument simply crumbles.

For fun, I've thought about reformulating the argument and turning it on its head. It would go something like this:

Atheists have a true desire to use Epicurus' Riddle in toppling the belief in God for rational people.
Atheists claim that Epicurus' Riddle is powerful enough to topple belief in God for rational people.
Yet rational people still believe in God.

 So, why appeal to Epicurus' Riddle?

In both instances, it strikes me that the logic is the same.  If my argument above doesn't logically follow, then I would think that the argument from evil also doesn't logically follow. Even given that the second argument is not discussing a perfect being, the premises are not as bold and rational people will seek to make rational decisions. One may say "perhaps the rational person is biased by his emotions, or perhaps he doesn't  understand the implications of the argument."  Those points are very possible and make the argument invalid, but prove my point--when other factors can be considered, the either/or structure of both arguments fail.
