Scientism tries to Turn Man into a Monkey

Many Christians are familiar with the classic book The Pilgrim's Progress by John Bunyan. For those of you who aren't, it's an allegory of growing in Christian faith where the protagonist named Christian meets some friends (such as Evangelist and Faithful) as well as many unsavory characters like Mr. Worldly Wiseman, Hypocrisy, and Talkative in his walk down the narrow path. While Bunyan wrote in the mid 1600's,the book is amazingly poignant for today.

One particularly striking section dealt with a character named Shame. Christian's friend Faithful recounts to him Shame's accusations against believers. Specifically, Shame claims the religious are basically weak-minded individuals, not living in the real world. He goes on to point out how successful and intelligent people don't believe in such things and how believing in Christianity forces one to ignore the scientific advancements and knowledge of the day. "He moreover objected to the base and low estate and condition of those who were chiefly the pilgrims of the times in which they lived; also in their want of understanding in the natural sciences." 1 So, Shame accuses the Christians of being willfully ignorant. Ignoring what he holds to be the true knowledge of science, Shame charges Christian with substituting the crutch of religion to salve his wounds.

Our Popular Conception of Science

Today, we are even more apt to hear such objections to believing the biblical message. This is in large part due to the over-emphasized view science is given in our modern culture. Science is understood in today's world to be the only reliable source of truth. One has only to look at the advertisements we use to sell products to see how much we esteem the concept of scientific veracity. If you really want to make your case for the potency of a product, just have your spokesman wear a white lab coat, begin his name with Dr., or explain how "tests have shown" the item to be more effective. If science has shown something to be true, then it must be true. And if there is a conflict between beliefs and what science has shown, then most people will assume that it is our beliefs that are in error, not science.

These assumptions are unfortunate, but not altogether unsurprising. As I've said before, science has helped humanity in incredible ways. Our lifespan have been extended by decades, we can modify our environment if we're too hot or too cold, and technology has made our daily chores easier. Our learning has also increased exponentially; we better understand the way the world works, we can predict certain phenomena and we've even visited the moon! So with all science has proven it can do, how could it not be real way to know truth?

Scientism's Claim to Truth

There are two problems we run into when discussing science and the way we know things to be true. The more egregious error is the one the easier to identify and argue against. That is the belief that only things that are scientifically verifiable are truly knowable and everything else is opinion and conjecture. This view is known a Scientism, and has had proponents such as Carl Sagan, Stephen Hawking and the late evolutionist Stephen Jay Gould. Noted skeptic Michael Shermer defined Scientism as "a scientific worldview that encompasses natural explanations for all phenomena, eschews supernatural or paranormal speculations, and embraces empiricism and reason as the twin pillars of a philosophy of life appropriate for an age of science." 2

The proponents of Scientism hold that "only things that are scientifically verifiable are truly knowable", is a true and knowable statement. However, that statement is itself unverifiable scientifically. One cannot construct a hypothesis to test for the statement's veracity. There's no way to go into a laboratory and run this idea through a battery of tests to see whether it can be falsified. Scientism, by setting a standard that cannot itself meets, undercuts its own existence. It becomes what we call a self-refuting statement. Because it does so, Scientism should rightfully be rejected as illogical.

Who Chooses the Standard of Comparison?

The main problem with our popular view of science, though, is more subtle and it therefore takes more care to identify. Because science has taken such a high role in our society, statements that are couched in a scientific approach are thought to hold more weight than other types of assertions. However, many who are purporting to advance a scientific view are really making philosophic statements - and they're making a lot of assumptions along the way.

A good example of this is one that Christian philosopher Francis J. Beckwith related to me at dinner one evening. He told of how he had become engaged in a discussion on origins through an Internet bulletin board whose members were primarily biologists and other scientists. One member was asserting the fact of evolution by noting how science has shown human DNA and chimpanzee DNA to be 98% identical. The biologist then concluded that this proves humans and chimps share an evolutionary ancestor.

Dr. Beckwith countered this claim by asking a simple question: Why do you choose genetics be your basis of comparison? It seems an arbitrary choice. Why not any other field of science, say quantum mechanics? Dr. Beckwith went on to explain that if you examine humans and chimpanzees at the quantum level, why then we're 100% identical! Our atoms move and act in exactly the same way as the atoms of the chimp! Of course, human atoms and the atoms of the table where I'm writing this also act identically. How about if we examine each via physics? Again, we're identical: each species will remain in motion unless enacted upon by an outside force, for example.

The scientists had a very difficult time understanding Dr. Beckwith's point, but it was simply this: one cannot start with science to understand the world. Science relies on certain philosophical rules in order to work at all. What was happening is the biologist was making philosophical assumptions and then using science to try and support them. The assumption in the claim above is that all life can be reduced to its genetic make-up, and everything you need to know about any living thing can be deduced from its DNA. It's this assumption that's flawed. It doesn't follow that if humans share 98% of their DNA with chimps that evolution is therefore a fact. But the scientists today aren't trained in logic or philosophy, so they have a lot of difficulty understanding that they are making flawed philosophical arguments and packing them in scientific facts.

Is a Changed Life a Valid Proof for God?

In arguing for God's existence, apologists will offer various points of evidence, such as the existence of something rather than nothing, the design of the universe, the existence of real moral values and duties, and so on. One point that philosophers such as William Lane Craig and others has offered seems strikingly different from these more objective facts: the fact that people who become Christians experience a changed life. Is such a subjective point valid when arguing for God's existence? I believe it is, but I want toreview a few reasons why.


One of the promises of Christianity is the believer will become "a new creation" (II Cor 5:17) and will be "born again" (John 3:16). The concept the Scripture is communicating is that people will experience real change in who they are and in their very nature. This is why people who share Christ with others will use their testimony as a point of evidence to the reality of Jesus.

Is The Experience Real?

Just because a change happening to an individual is subjective (that is we must rely on the testimony of the indivisual to tell us what they are experiencing), it does not diminish the reality of that experience. Scientists study the effects of mood-altering drugs on patients, which are similarly subjective, but they can with various degrees of certainty claim that it is the drug that is causing the patient's mood to be changed, and not other conditions.

The strength of the argument then lies in finding whether the changes are a real result of something happening outside the individual, or is it merely the belief of the individual himself that is causing the change. Dr. J.P. Moreland states the problem in this way, "It is possible to argue that all such experiences are merely psychological or perhaps the result of sociological factors like peer pressure. One could hold that some sort of placebo effect is going on."1

If such a placebo effect is occurring, then it is not God changing people's lives, but it is the people believing their lives are changed that are responsible for the said change. If this is true, then we don't prove God at all.

So, how can we determine whether a placebo effect is happening? Or how can we tell if some other factor is causing such a change? Moreland lays out three main points as to why we can claim the Christian experience as valid:

  1. The claim of personal religious experience of God doesn't deny psychological factors, it merely claims that they are not enough in themselves to explain a transformed life. This means that people will of course be subject to both social and psychological influences. However, these influences do not by themselves have adequate power to explain religious transformation. In fact, religious experiences exhibit properties that are unique to themselves.
  2. Attempts to reduce religious transformation to psychological factors must assume there are some common factors that would cause the similar experiences. However, as we see more diversity in the causes of people's lives being changed, that explanation becomes less likely to be true. In other words, as the sample size grows, and the backgrounds and other variables are eliminated as a common cause, the more difficult it is to ascribe such a change to a psychological cause.
  3. Finally, religious transformation in Christianity is tied to objective events (the resurrection) and an objective interpretive grid (the Bible) which render transformation probable. This point is perhaps the most important. These experiences are not based on only the belief of the subject, but they are linked directly to an event that is historically verifiable. The Bible also predicts that this type of experience would happen to the believer (as shown in the second paragraph above).2
Now, I am not arguing that we should accept all claims of religious experience as actual. We must approach these as we would any other truth claims: in a discerning manner using the points I've outlined above.

How We Should Approach Subjective Truth Claims

Josh McDowell demonstrates how he approaches subjective claims. "There are two questions or tests I apply to a subjective experience. First what is the objective reality for the subjective experience, and second, how many other people have had the same subjective experience from being related to the objective reality?"

McDowell then goes on to use an example of a man who claims a fried egg over his ear gave him joy and peace, and shows how this flunks his test. However, when judging claims of changed lives from believing in the objective reality of Jesus Christ and His resurrection he says "the evidence is overwhelming... that truly millions from all backgrounds, nationalities and professions have seen their lives elevated to new levels of peace and joy by turning their lives over to Christ."3

Because there exists a vast number of people from all cultures over nearly two thousand years who made similar claims of transformation bolster our position that their experiences come from outside of themselves. And by understanding these three points, we can make a viable claim that God is really working in the lives of those who believe in Him and therefore He exists.

Science, God, and Knowing


Today, people look to scientists to find the answers to our problems in the world. But does science have limits? Are there other ways to know something as fact? And how are questions about God and religion tested scientifically? In this series of audio podcasts, Lenny shows why scientific objections to God fail.
