Why Claiming Religion is False Undercuts Darwinism



According to atheists like Daniel Dennett, religious belief is a falsehood that arose via evolutionary processes. In his debate with Alvin Plantinga on the topic "Science and Religion: Are they Compatible?" Dennett said "I think that the natural sciences can provide us with a very compelling explanation of why and how people came to believe in God, which does not at all suppose that it would be a true belief. But if we can diagnose the etiology of the belief in God, we can even make predictions about how and why this would be the case and how it would work. Then, we have undercut the presumption that because so many people believe in it, it must be true."1

This kind of thinking is fairly prevalent in certain atheist circles, used mainly to explain why belief in a god or God is found across all cultures throughout all times in human history. The universal nature of religious belief poses a bit of a dilemma for the atheist, as it demonstrates the desire to reach out to a higher intelligence is as natural as wanting to fill one's stomach. C.S. Lewis famously observed:
Creatures are not born with desires unless satisfaction for these desires exists. A baby feels hunger; well, there is such a thing as food. A duckling wants to swim; well, there is such a thing as water. Men feel sexual desire; well, there is such a thing as sex. If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world.2
If Lewis is wrong, it means that most of humanity has a false desire to believe in God. But given its falsehood, how can naturalists explain its universality? The answer that Dennett and others offer is that such a belief was in its way evolutionarily advantageous. Dennett argues for this view in his book Breaking the Spell: Religion as a Natural Phenomenon. In the debate he explained why he believes he's justified in looking to science to explain religious belief: "If we have a good theory that explains how massive systematic falsehoods could arise in the human population and be maintained over generations, then that in itself is a pretty good reason for supposing that we've got a good handle on this, better than their handle on science."3

The Elephant in the Room

So, Dennett and others holds that 1) religious belief arose naturally via evolutionary processes4 and 2) it is a belief that is false. It follows logically from those two premises that evolution produces false beliefs. Not only does evolution produce false beliefs in certain people or in a small population, but if the two premises are correct, evolution produces, to use Dennett's words, massive systematic falsehoods that arise in the human population and are maintained over generations.

Here's where Dennett runs into a wall, though. The very fact that our reasoning ability exists at all on a naturalistic understanding of the world is due to evolution on his view. We trust our reasoning abilities to give us true facts about the world. One of those true facts that Dennett and other naturalists hold is there is no God, evolution can account for our belief system. But why should I think that belief is any more true than the belief that God exists, if Dennett is right?

In fact, why should we place our trust in human reasoning ability at all if evolution produces huge whoppers of falsehood that permeate all of humanity? Why should we trust our evolved monkey-brains reason to ward s some kind of external truth about where we came from, given Dennett's explanation?

As I've argued in True Reason: Confronting the Irrationality of the New Atheism:
Basing our ability to reason on a cause-and-effect model doesn't make sense. Reason is not the kind of thing that can be explained by examining the makeup of the brain or its physical processes. Reason must be oriented toward an objective external reality and our ability to tap into that reality. In fact, if naturalism is true, it means either that what we take to be rationality is either in no way grounded in external, objective truth (and as such cannot be called rational), or we're fooling ourselves into thinking that rationality exists at all.5
It seems to me that by holding to religion as an evolutionarily produced falsehood, the naturalist loses his entire foundation to assert that his explanation is itself true. He's undermined not simply evolutionary belief but rationalism itself.

If You Want to be Reasonable, Then You May Have to Believe



I've had the opportunity to interact with many people who would classify themselves as either atheists or agnostics. (Sometimes, they try to classify themselves as both, but that's an untenable position. ) While theists and atheists will argue back and forth on the legitimacy and support for each one's position, it is the agnostic position that intrigues me the most. Many agnostics claim to be reasonable people who rely on evidence and rationality to come to a conclusion about God. But is the person who withholds a belief always more reasonable than one who accepts it? In a word, no.

To Hold a Justified Belief

The Stanford Encyclopedia of Philosophy identified Roderick Chisholm as "one of the most creative, productive, and influential American philosophers of the 20th Century."1 Chisholm studied an area of philosophy devoted to understanding how we know things, called epistemology. His book A Theory of Knowledge provides a strong framework for what constitutes a rational belief. There, Chisholm explains that to have not simply a belief (which anyone can hold about anything—reasonable or not), but to have a justified belief is to "say something about the reasonableness of that belief." 2 Chisholm goes on to explain that when we make statements like "one who believes in X is at least as justified as one who withholds belief in X" we are making a claim that each position is equally reasonable; that is there is just as much reason to withhold that particular belief as there is to affirm that belief.

However, Chisholm makes the point that if arguments or evidence are presented that argue for a particular belief, the equation changes. To withhold a belief is to be neutral, not to take sides either way. For example, I'm completely neutral as to whether I think the Philadelphia Phillies will be playing in the World Series. I do not follow baseball closely and I don't know the standings of the teams. But after I look at the standings, even for a moment, I would no longer be neutral. Given the Phillies are last in their division and have a record of 47 wins versus 73 loses, it would be unreasonable for me to remain neutral on this question. Knowing the standings doesn't give me certainty about my belief, but I'm more justified in holding to the belief that the Phillies won't make it to the World Series.

Chisholm argues in a similar way when he writes that "St. Augustine suggests that, even though there may be ground to question the reliability of the senses, most of us are more justified most of the time believing that we can rely upon them than believing that we can not rely upon them" (emphasis in the original).3 Because there is good evidence that our sense tell us the truth about the world most of the time, it is more reasonable to believe what our senses tell us rather than doubt that they are providing truthful information. If additional evidence is offered (i.e. the person is having an extraordinary sensory experience and has taken a hallucinogenic) then we can adjust the justification to that additional information and say one may be more justified to not believe their senses in that instance. However, neutrality, what Chisholm calls counterbalanced, is a difficult position to maintain.

Can Agnostics Be Counterbalanced?

Given the fact that arguments and evidence changes the equation of belief, I must question those who claim to be agnostic on their position. It is not reasonable to withhold a belief if there are facts that argue either for or against a position. The agnostic wishes to stay neutral on the question of God's existence, but we know quite a bit that makes neutrality a less reasonable position than that held by the theist. We know that something doesn't appear from nothing. We know that consciousness has never materialized from non-conscious material. We know that at least some people have reported seeing miracles and we know that includes the reporting of seeing the resurrected Jesus. All these facts point to the existence of a God. If one were to argue against these as evidence for God's existence, then the burden would be upon that person to show why their approach isn't assuming atheism rather than agnosticism. But to simply claim to withhold belief given the facts above is simply not justified. It is what Chisholm would call unreasonable.

The Incomprehensibility of Naturalism (Quote)

Dallas Willard spoke at an academic symposium in 1998 dealing with the topic of "The Christian University in the Next Millennium." Willard's paper, entitled "The Redemption of Reason," laid out a powerful argument, with his thesis being "only the body of Christian knowledge and intellectual method can redeem reason. There, Willard said:

This is the fundamental fact of our time, from which reason must be redeemed: the incomprehensibility of reason and knowledge in naturalistic terms. Reason and knowledge are not to be found in the sense-perceptible world. It’s just that simple. If you have to understand everything in terms of the sense-perceptible world, reason and knowledge are gone. That is why you have the many strained and forced interpretations of knowledge and consciousness and reason, including all of the creative arts, and all of the areas of expression of the human spirit that we study in the academy—the forced interpretations of these as sociological, as behavioral, or even chemical. Even the interpretation of love has to be put in a naturalistic mold. I’m reminded of a man who said "Sawdust is wonderfully nourishing if you will substitute bread for it." When you try to put truth into the naturalistic mold, it’s gone. It is the same when you try to put evidence, when you try to put logic, logical relationships, probability, all of these fundamental things into a naturalistic mold. There are many dimensions of evidence, and many of them fall in a very variegated way within what we would call "sense-perception," but not sense-perception in the narrow sense that the naturalist wants to take it. And so we have to simply understand that the sociological, behavioral and chemical attempts to treat knowledge, reason, and creativity are due to the fact that the only categories available are the ones posed by the naturalistic world-view.

So of course, that’s why I say only the Christian knowledge-tradition can save knowledge in our time. If we don’t have that, we have a constant struggle within our Christian schools with what one writer has called "the problem of stemming the drift". The question comes up, "What is it about higher academic life that seems to make it such a hard-and-fast rule that given enough time, any institution, no matter how rooted in orthodoxy, will sooner or later slip away from its anchors?" In an article that appeared in "World Magazine" in May of 1997, Joel Beltz tries to address this. He quotes Gaylen Byker, President of Calvin College, on the problem. "The problem" is: How do you secure faculty for first-class programs in Christian colleges, without losing them to the secular mindset? When you’re hiring faculty you begin to think thoughts like, "Is it really important that a math professor hold to his school’s theological position?" With regard to experts in the various subject matters, Byker comments—and it’s very true in this simple statement he makes—"It’s hard to justify hiring a third-rate Christian when you can get a first-rate non-Christian." Those are his words, and I think we all understand this is a serious problem, not something to be dismissed.
Check out the rest of Willard' paper here.

Five Things Your Worldview Must Account For

Recently, Tom Gilson posted an open question on his blog. He asked those that identify themselves as atheist or agnostics, "What does your worldview explain better than Christianity?" Gilson was careful to distinguish an atheistic belief from a worldview, given that atheism is the denial of God's existence but isn't robust enough in itself to qualify as a worldview.



There have been many answers to the question received so far from atheists, but most have been disheartening. It isn't because I may or may not disagree with them. They are disheartening because none of them describe a worldview. They each take on one aspect of understanding the world, namely the scientific enterprise, but leave so much more out of their answers.

I've explained before that a worldview is the way one sees and interprets the way the world works. It's basically a framework for understanding and interpreting the various facts we encounter in our lives. That's why any attempt to outline a worldview must account for at least the following five things. I'd like to go over each of these quickly.

1. One's understanding of origins

The concept of origins is central to interpreting many things in the world. Some of the key questions of origins include: Where did we come from? Why is there something rather than nothing? What is reality? Where do good and evil find their foundations? These are all crucial when seeking to make sense of people and situations. For example, if you hold that human beings bear God's image, you are going to have a different perspective on the nature and dignity of issues like assisted suicide, abortion, and the equality of all people.

2. One's understanding of rationality

Reason is a key component of understanding our world, so providing an account of rationality and why or if we can rely on our reasoning skills is important. How does reason work in the world? Is it a reliable way of knowing things? How can one know that?

3. One's understanding of purpose

Another primary factor in interpreting the world is identifying if there is any kind of purpose to our world and if so, how can one discover that purpose. The understanding of telos—that there is a design or an ultimate end to the cosmos, humanity, or even to each individual will play a huge part in how one values others, the environment, and many other areas.

4. One's understanding of morality

Morality and its grounding has been something I've written about quite a bit, but every worldview must have some kind of understanding of what morality is and where it comes from. Societies simply cannot function without certain agreed upon notions of right and wrong. Even if your worldview holds that objective morality doesn't exist, it must be expressed and integrated into your explanation of how society determines values.

5. One's understanding of ultimate ends

Lastly, every worldview has some kind of account of what our ultimate ends are. Is there a reality beyond this world? Do we cease to be when we die? How does one discover this end and how does this life relate to any our ultimate end? This along with the question of purpose are key to helping us decide how to act in various circumstances.

One of the reasons I hold to the Christian worldview is it answers each of the five questions and does so in a way where each area is integrated with the others to form a coherent whole. Christianity gives a single picture of the world, where each of these five areas makes sense with 1) the way we observe our world to work and 2) makes sense with each other. They follow naturally from one to the next. Without an integrated, coherent worldview, values and judgments become confused or contradictory.

So, what's your worldview? Have you thought about each of these five areas? Does your worldview not only account for each, but does it do so in a way that isn't ad hoc, or happenstance?

Darwinism's Fatal Flaw (podcast)


The idea that complex life arose through nothing but natural means is a hallmark of modern evolutionary theory. But what if we discovered a problem with Darwinism that was so fundamental, all of science wouldn't work? In this podcast series, Lenny highlights a new argument that shows why evolutionary naturalism is a non-starter.

Jesus and Logical Fallacies: The False Dilemma

There have been many times where I've been speaking to a non-believer who tells me that he would rather place his trust in science and reason than in faith. Versions of this include "facts rather than religion" or "knowledge over ancient belief."



Such objections are certainly not uncommon today, even though they are completely illogical. Each one exercises a logical fallacy known as a false dilemma. A false dilemma tries to limit one's choice between only two options when there may be more options available. To use a popular example, imagine a man on trial. As he sits in the witness stand, the prosecutor comes to him and asks, "Is this the first time you've beaten your wife, yes or no?" Of course, either answer to such a question immediately incriminated the man. The third choice of "I have never beaten my wife" is never offered by the prosecutor, which sets the defendant up with only two options, each of which places him in a bad light.

Why Faith Versus Reason is a False Dilemma

In the objections above, the ideas of faith, religion, and belief are all positioned as incompatible with science, facts, and knowledge. But the assumption that these are incompatible is itself not true. For example, the multiverse theory is based on certain mathematical beliefs and assumptions. There exists no observational data for other universes, nor will there be given that our universe is a closed system. Therefore, scientists who hold to the multiverse theory are doing so based on certain beliefs and a faith in the models they have constructed. Does that disqualify the multiverse theory from being classified as science? Will those skeptics disavow it because they would rather place their trust in reason? Of course not.

Similarly, Christianity is based on certain facts, such as Jesus' resurrection from the dead, based on the historical accounts. Christians use arguments to show that the existence of God is a reasonable position to hold. Reason and evidence are the foundation of Christianity, which just like the multiverse model shows that faith and reason are not exclusive but work in concert.

How Jesus Answered the False Dilemma

Sometimes people offer false dilemmas intentionally as a strategy, such as our lawyer example above. However, it's probably more common for a person to not realize there are more choices than the two presented when he or she is presenting the argument. Still, it is important to highlight the dilemma and show it to be false.

The Gospel of Luke provides us with an example of how Jesus faced a false dilemma. In Luke 20:19-26, the Pharisees were trying to trap Jesus into incriminating himself. Luke tells us that they asked him "Teacher, we know that you speak and teach rightly, and show no partiality, but truly teach the way of God. Is it lawful for us to give tribute to Caesar, or not?" This was cunning, because if Jesus replied that paying taxes was wrong, he'd be considered a traitor to Rome, but if he said it was OK according to the Jewish law (that is the Old Testament commands) to give a tribute to Caesar, then the would be sanctioning support for a Gentile ruler when Israel's only allegiance should be to God alone.

However, Jesus didn't fall for it. Luke reports:
But he perceived their craftiness, and said to them, "Show me a denarius. Whose likeness and inscription does it have?" They said, "Caesar's." He said to them, "Then render to Caesar the things that are Caesar's, and to God the things that are God's." And they were not able in the presence of the people to catch him in what he said, but marveling at his answer they became silent.
In Jesus' answer, he brilliantly splits the horns of the dilemma. There are more than the two options of allegiance to God or allegiance to Caesar. One can be a good citizen of the state while disagreeing with some of its positions. The Pharisees weren't offended at the graven image of Caesar so much that they refused Roman money. They simply didn't want to give it back in taxes. Thus Jesus's answer shows that one can be a good citizen and not offend God. In fact, he may have thought of Malachi 6:8, which teaches that all believers should seek to do justice, to love kindness, and to walk humbly with God. Paying for the services of Rome is part of doing justice.

In highlighting the false dilemma the Pharisees offer, Jesus gives us one example of how to better defend our faith. Jesus' use of logic had the effect of silencing his detractors while teaching new truths to his audience. This is just one example of Jesus using logic and reasoning in his interaction with others. We need to prepare ourselves to do likewise.

To Witness Like Jesus, Use Logic and Reason

Christians will many times hear atheists make the claim that faith is somehow opposed to reason.  Most people of faith that I talk with reject that idea. They don't believe that one must choose either faith or reason. However, there are quite a few Christians who think that faith and reason are separate realms that may coexist, but they don't touch. For some Christians, think this idea is comforting. They have taken certain slogans of "bumper-sticker" Christianity such as "Jesus is all I need" and think that such a position is powerful enough to ward off objections. Worse, they think that the same approach works with evangelism.



This is not only a travesty, it is antithetical to who Jesus is and how he evangelized. Jesus was an intellect. In fact, Jesus was the smartest man who ever lived and reason is at the core of who he was. We can see that clearly when the scriptures identify him as The Logos (John 1:1). The Greek word logos is usually translated "The Word" in our English Bibles, but it has a richer meaning. "The Word" is a concept of knowledge. As Merrill F. Unger puts it, "Words are the vehicle for the revelation of the thoughts and intents of the mind to others."1 In fact, logos is where we get the English word "logic."  The word holds the concept of "consideration or evaluation, reflection, or in philosophy, ground or reason."2

Because Jesus is the Logos, it shouldn't surprise anyone that Jesus used logic in his efforts to evangelize others. Jesus' aim in utilizing logic is not to win battles, but to impart understanding or insight in the minds and hearts of his audience. Dallas Willard writes:
 (Jesus) typically aims at real inward change of view that would enable his hearers to become significantly different as people through the workings of their own intellect. They will have, unless they are strongly resistant to the point of blindness, the famous ‘eureka' experience, not the experience of being outdone or beaten down.3
We read of clear examples of this in scripture, such as Jesus' interaction with the woman at the well in John 4 and the different exchanges with both the Pharisees and the Sadducees in Mathew 22.

Jesus even rebuked His disciples for not thinking rationally. In Matthew 16, Jesus is warning his disciples to "beware of the leaven of the Pharisees and Sadducees." However, they miss his point, and instead begin worrying that he was going to get mad at them because they didn't bring enough bread for the trip.  Jesus replies:
You men of little faith, why do you discuss among yourselves that you have no bread? Do you not yet understand or remember the five loaves of the five thousand, and how many baskets full you picked up? Or the seven loaves of the four thousand, and how many large baskets full you picked up? How is it that you do not understand that I did not speak to you concerning bread?4

Stronger Minds Mean Stronger Convictions

Reason is part of the model Jesus gave us to learn, to discern, and to share our faith with others. As disciples of His, it makes sense that we should follow his example. However, there are some real benefits to incorporating logic and reason into our witnessing efforts. By allowing others to "discover" these spiritual truths, they would become more convinced of the reality of Christ and Christianity than those looking for a feel-good faith. Rational believers are much stronger in their convictions and their faith. They are also less likely to be swayed from contradictory teaching since they know that their faith is not "blind" or transitory, but anchored in the truth of the Logos. They know that their beliefs have their origin in history and they provide real answers for a world in need. So, let's think a little harder and incorporate rationality into our efforts to share the truth of the Gospel with others. Jesus would have us do nothing less.

Why Naturalism is Simply Unbelievable

Naturalism is simply unbelievable. I don't mean unbelievable in the fantastical sense, although I do think there's a lot of hand-waving that goes on to try and excise any supernatural explanation as to why we exist. I mean, the viewpoint is unbelievable in that its own assumptions destroy itself. It is illogical to hold to naturalism.



The naturalist wants us to believe that the natural world is all that exists; we came about through evolutionary processes and our minds are one of the products of that process. Given the survival of the fittest paradigm that rives evolution, the naturalist must also assert "What your beliefs are don't matter nearly as much as what the survival value of your actions are." In fact, they do this when discussing religion all the time. Religion isn't true, they would assert, but it served an evolutionary purpose.

To use an example, picture an overweight man who is running. Now, the man may believe he has a better chance at survival if he runs because he puts his body in better shape, reduces the chances of heart attacks, and is generally more fit for the tasks of survival. However, the man may equally believe that running is an act of worship to the life-god and it drives out the fat demons that plague much of his tribe. Either belief produces the same result: the man runs and the man has an increased chance of longevity. Either belief helps him survive equally well. It doesn't matter which is true on an evolutionary worldview because evolution is all about survivability.

Reason Offers No Evolutionary Advantage

Because all evolution cares about is the survival of the individual, reason alone offers no evolutionary advantage. In fact, evolutionary theory proves this. According to all New-Darwinian models, there was a time on the earth where there existed no rational thought whatsoever! Animals were primitive and they had no capacity to reason, yet they survived just fine. They mere responded to external stimuli and adjusted their behavior. They don't know why the water is here and not somewhere else; they simply desire water.

This is why you can get a pet dog or cat to chase a flashlight beam or laser pointer on the floor. The dog bites at it and it isn't there, yet he will continue to chase the beam! Your pet is simply responding to stimuli. They aren't thinking abstractly. A dog never wonders what it's like to be a cat!

Knowing that the earth circles the sun as opposed to the sun circling the earth gives us no evolutionary advantage whatsoever. We gain nothing in terms of the advantage to put food in our stomachs or to shelter us from the cold nights. This is because reason and responses are categorically different kinds of things. There is a difference between neural stimulation and mental reflection. The naturalist will say "All reason is is a process of neural stimulation" but C.S. Lewis argued that natural selection only operates by eliminating biologically harmful responses and increasing responses linked to better survival. He writes:
It is not conceivable that any improvement of responses could ever turn [the animal's thoughts] into acts of insight, or even remotely tend to do so. The relationship between response and stimulus is utterly different from that between knowledge and the truth known.1

Beliefs Can be Counter-Intuitive

Sometimes we have to believe things that are completely counter-intuitive based on our stimulus. Exercise is a good example of this. For me, it is counter-intuitive when lying in my comfortable, warm bed to get up and put my body in a situation designed to cause strain and pain. So the desire to exercise doesn't come from external stimuli, but from our reasoning capabilities. We do the things that are counter intuitive to everything the body is telling us because we have a reasoned that that's a better way to go. It doesn't make sense evolutionary because the benefits are a long way off.

 Alvin Plantinga agrees when he writes:
Fleeing predators, finding food and mates — these things require cognitive devices that in some way track crucial features of the environment, and are appropriately connected with muscles; but they do not require true belief, or even belief at all.

The long-term survival of organisms of a certain species certainly makes it likely that its members enjoy cognitive devices that are successful in tracking those features of the environment — indicators, as I've been calling them. Indicators, however, need not involve beliefs (emphasis added).2
There are many of our beliefs that lie completely outside the realm of evolutionary advantage at all. The belief that evolution is true is one of these. The problem is the evolutionist doesn't have good grounds for holding to his own evolutionary tale, since the evolutionary framework gives no grounds for holding that any of his beliefs are true. If evolution is true, then reason isn't trustworthy. How does one escape that when every belief the naturalist has is a product of evolution? Assuming naturalism is to doubt the reliability of reason itself.

What If You Can't Be Reasonable Without Faith?

Sam Harris, one of the new atheists, in his book The End Of Faith defines faith this way:
The truth is that religious faith is simply unjustified belief in matters of ultimate concern—specifically in propositions that promise some mechanism by which human life can be spared the ravages of time and death. Faith is what credulity becomes when it finally achieves escape velocity from the constraints of terrestrial discourse—constraints that you're leaving like reasonableness, internal coherence, civility, and candor. 1
Of courses, Harris is completely wrong in his view of faith. Some aspects, such as his attempt to divorce faith from civility are a bit laughable—especially when it is the "reasonableness" of Harris that tries to label any person of faith as lost in outer space.



Sam Harris is a master at creating straw men when discussing religious belief, and that's just what this is. But the misconception has been around a lot longer than Harris. It was probably expressed most succinctly by Mark Twain who said, "Faith is believing in what you know it ain't so." But people of reason can be also people of faith, in fact the Christian practice of apologetics is designed to give reasons and evidence for faith. Part of the confusion is polemical; atheists like Harris have a desire to make people of faith look as bad as possible, so he writes that the faithful are uncivil and deceitful. But Harris isn't being reasonable here. I've written before about  Harris's misdefinition of faith; you may read articles here and here. I think another key problem with Harris; view is that he misunderstands the concept of reason as well.

What is Reason?

Everyone assumes they know what reason is, but reason involves thinking rightly about the world around us. Ultimately when we talk about reason we talk about a rational enterprise (using our minds) to aim at an objective criterion. We avail ourselves of what we know to try and make sense of ourselves, the world and our experiences. Basically, being reasonable means we are looking for truth by thinking well.

Since reason involves looking for truth, it then becomes important to realize that reason includes going beyond ourselves. Truth is an objective thing; it's something "out there" not just something subjective. Any truth claim lies outside of the individual. Truth may stand in contrast to the experience that an individual has, including even empirical/sensory experience

For example, your senses may tell you that the Sun circles the Earth. If we look up, we watch it; we can see it with our eyes. Isn't that enough proof? No, it isn't. Isn't that empirical evidence? Yes, but just a bit of empirical evidence alone may lead you astray. Just because we see something with our eyes it is not necessarily the end of the matter. How do we know that our eyes are not telling us the truth? We have to find new facts and we then use our reason to compare different sets of data.

When Copernicus offered his model of the solar system where the earth circles the sun, part of the driving nature to his belief is that the Creator of the world would prefer simpler and more beautifully designed way to arrange the planets' motion:

For Copernicus as for many ancient philosophers the sky is the visible God; therefore the study of the movement of the celestial bodies is the most excellent way to the invisible God. The Creator is the great architect of all things; in the cognition of the mathematically simple structure of the universe man will become united with Him. It is suggested that these theological ideas gave Copernicus the pertinacy to work out his heliocentric system despite the misgivings of contemporary Aristotelian physicists.2

Copernicus, then, sought to explain the universe that was as satisfying to his faith as it was to his eye. He dedicated the book containing his findings to Pope Paul III and said:
I am not so much in love with my conclusions as not to weigh what others will think about them, and although I know that the meditations of a philosopher are far removed from the judgment of the laity, because his endeavor is to seek out the truth in all things, so far as this is permitted by God to the human reason, I still believe that one must avoid theories altogether foreign to orthodoxy.3
 There was no way to deduce Copernicus' view using sense data alone. Copernicus showed mathematically why his model made more sense, and part of the attractiveness of his model was its simplicity and beauty. But Copernicus says that he wished to remain orthodox in his understanding of the world and it was his use of reason as given by God that led him to his view of a sun-centered solar system. Metaphysical faith helped propel the Copernican model forward.

When one seeks to be reasonable, it means that he must weigh all the information at his disposal. That may include considering ideas that are not based in empirical observation alone, but ones that have a basis outside of nature. If God's existence makes more sense out of things like the emergence of life from nonlife, the emergence of consciousness and the orderly nature of the universe, then, barring actual evidence to the contrary, it would be unreasonable for us to believe there is no God.

I wish Sam Harris and other atheists who like to bring up Copernicus would look at how reasonable Copernicus really was. I also wish that some of the New Atheists would also hold to not being "so much in love with my conclusions as not to weigh what other think of them." That would be a very reasonable thing to do.

Reason and Faith Are Not Opposites

I don't know how many times I've heard the claim that "religion is just a crutch for the weak-minded". Many of the popular atheists in print today like to try and say that belief in God is the opposite of being rational.1 Others I've had conversations with dismiss faith as being the opposite of knowledge. I remember having lunch one day with some mutual friends. The discussion turned to matters of belief and one girl immediately said that we couldn't really know truth at all, to which I objected, saying that there are a lot of things we can know. We know 2 + 2 = 4, the earth circles around the sun, and Shakespeare wrote Hamlet. She immediately objected and said "that's not truth, those are facts!" I answered, "Well, are those facts true or not? What makes the statement 2 + 2 = 4 a fact and 2 + 2 = 5 not a fact? Isn't it an idea known as truth?"



As you can see, this girl was trying desperately to draw a line between matters of faith and things that fall in the category of math and science. She was trying to say that faith is merely a personal choice, like which ice cream flavor is best. But God either exists or He doesn't. Jesus of Nazareth either really lived, really was crucified, and really rose from the dead or He didn't. These statements aren't nearly the same as liking a particular ice cream. They are questions of history and of existence. That means they can be investigated and facts can be discovered. Reasons for their truth or falsehood can be offered. And if it's found that there are good reasons for believing in these claims, then we are only unreasonable if we refuse to believe them.

So reason and faith are not opposites. The Christian faith rests upon the reasons we have for believing in things like the resurrection. In our Proverbs passage, God says that we are to cling to "the words of the wise"; we are to cling to "excellent things of counsels and knowledge." Wise words, counsels, and knowledge are all objective terms; words are only wise or knowledgeable if they are true. And if something is true, then it must be rational to hold to such as belief. That's why God says we can know the certainty of the word of truth. To do anything else would be irrational!

In his book The God Delusion, Dawkins writes that belief in God is "a persistently false belief held in the face of strong contradictory evidence"(p.28) which is tantamount to shutting your eyes and denying what's in front of you.

Taking a Chance that There is No God

A few years ago, I was invited to address several hundred college students at the University of Northern Colorado. It was a great time. I had invited Dr. Paul Copan to join me and the two of us were able to meet with the Christian clubs on campus first and give them instruction on how to argue convincingly for the Christian faith.

The main event was held in the evening, where Paul first gave an address to the student body as a whole, comparing the Christian worldview to the naturalist's worldview and demonstrating how Christianity is the more coherent belief system. I then joined Paul for about an hour of Q & A with the students.

The questions were powerful and interesting. Many students were very intrigued with the idea of Jesus providing an atoning sacrifice for us. The concept that there were moral absolutes and individuals would be held accountable for violating those moral standards seemed to spur on a lot of activity.


One student who we talked with classified herself as an "agnostic humanist". She had several objections to the Christian concept of eternal punishment from a God who hasn't given us enough proof to believe in Him. This is a classic objection – one that Bertrand Russell used. However, Paul and I repeatedly discussed the real evidence that's available to demonstrate the existence of God. If one chooses to ignore that evidence, you cannot blame God for not providing it.

One point we talked on repeatedly was the creation of the universe and the creation of life. We discussed the English scientist Sir Fred Hoyle's calculations about the improbability of life being formed spontaneously. In his 1981 book Evolution from Space (co-authored with Chandra Wickramasinghe), he calculated that the chance of forming the required set of enzymes in sequence for even the simplest living cell was one in 10 to the 40,000th power. Since mathematicians generally agree that anything above one in 10 to the 50th power is classified as impossible, that's a pretty powerful number. However, she kept holding onto her doubt, saying "but there's still that one chance."

I found such a statement silly. It's like saying if you're broke, you shouldn't look for a job but buy lottery tickets instead since there's still a chance you may win the lottery and never have to work again. That's not thinking rationally, that's just being childish. It's saying "I'm not going to believe this no matter what you say!" Now, you can hold that position. However, you cannot still maintain that there isn't enough evidence to believe in God or that God would be cruel for punishing you for your false beliefs.

I will say that everyone there was very polite and appreciative that we didn't talk down to them or preach at them, but we were treating them as thinking individuals who could be reasoned with. They enjoyed the exchange and as we answered questions; we had the opportunity to lay out the Christian plan of salvation clearly for all to hear. The most exciting time came when one questioner asked, "O.K., so suppose I believe what you said, that the resurrection is true. What do I do next?"

Once the Q & A time ended, Paul and I spent the next two hours answering questions with a group of about fifteen kids who followed us down to the Starbucks cafe that was set up downstairs from the meeting hall. It just reinforced to me how hungry these kids are for real interaction, for being treated as adults and for real answers to be provided for their questions.

I have been very blessed to be a part of this opportunity and I pray God will continue to open the doors for Come Reason to reach more kids for Christ. I ask that you can help us as well, by praying for outreaches such as these and by supporting our ministry financially. For those who wish to contact me about an event for their church, youth group, or school, click here. And for all my friends in the U.S., have a happy Labor Day holiday.
And let us not grow weary of doing good, for in due season we will reap, if we do not give up. So then, as we have opportunity, let us do good to everyone, and especially to those who are of the household of faith.
—Galatians 6:9-10

What's the Conflict between Faith and Reason?


We constantly hear that faith and reason are opposites; if you have faith in something, you’ve left reason behind. Do Christians follow a "blind" faith? Is reason the enemy of faith? In our most recent podcast, Lenny shows why there is no real conflict between faith and reason.  In fact, as its history has shown, Christianity is an inherently reasonable faith.

Defending Your Faith May Help Save a Christian



Why should Christians learn how to defend their faith? Many  people think that while specialists like professional apologists can argue for Christianity, it isn't necessary for the person in the pew to know all those things. Perhaps it's better to ignore the Jehovah's Witness or Mormons knocking on your door, rather than get into countless arguments. However, such an attitude may be more dangerous than you know, and we can lose church members because of it.

In this short video, I tell a story about one man who left the Baptist church to become a Jehovah's Witness because his pastor wouldn't help answer the objections they gave him. Apologetics can help keep Christians in the fold as well as provide reasons for those outside the faith.

Sam Harris' Wrongheaded View of Christian Faith

Photo courtesy Auren Hoffman.
If I ask Christians for a biblical definition of faith, many times I have Hebrews 11:1 quoted to me: "Faith is the assurance of things hoped for, the conviction of things not seen." But, is that the end of the story? Sam Harris, in his book The End of Faith, takes Hebrews 11:1 as an example of how Christians are not reasoning, how faith is diametrically opposed to reason. He writes, "Read in the right way, this passage seems to render faith entirely self-justifying: perhaps the very fact that one believes in something which has not yet come to pass ( 'things hoped for') or for which one has not evidence ('things not seen') constitutes evidence for its actuality ('assurance')."1

Obviously, Sam Harris is not a Greek scholar, nor is he a biblical scholar. He knows nothing about exegesis and he's just flat wrong on this, but he wants to prove his point. The assurance of things hoped for does mean the assurance of future things. Faith does deal with those things that we don't necessarily know, or that we don't have 100% confidence in. By the way reason deals with things we don't necessarily have 100% confidence in. You can reasonably believe something or you can claim you know something with less than 100% confidence.

As an example, think about a man dating a women he is considering marrying. He talks with his friends and says, "I think it's time to ask her to marry me." His friends may reply, "Well do you think she will say yes?" A reasonable response would be, "I have faith that she's going to say yes so I'm going to ask the question. If I had no faith that she would say yes, then I wouldn't ask at all."  Is such a faith a blind faith? Or is it based nio years of involvement and growing to know one another? I had faith that my wife and I would be compatible together as husband and wife. How can I know that? The only way to know how compatible we are is to become husband and wife. We cannot know that beforehand.

When we talk about "the assurance of things hoped for," it is not merely something which does has not come to pass. When we talk about "the conviction of things not seen," it is the writer using a Hebrew idiom where if they wanted to stress a point or add emphasis they would repeat it. That's what the writer of Hebrews is doing here. The lines "The assurance of things hoped for, the conviction of things not seen" is the same phrase said differently. It's a linguistic device.

Both Sam Harris and Christians need to realize that the Bible isn't meant to be taken so superficially. Hebrews 11:1 it is a good definition of one aspect of faith. It is not the sum total of what faith means, just as saying God is love is not the sum total of all that God is. God is also defined as a Spirit. God is also defined as a consuming fire. We are told many things that God is in the Bible and love is one aspect of God's character, but it's not the sum total of God's character. God has more depth to Him than merely love. Similarly, Hebrews 11:1 does not provide a complete definition of faith. One must take the passage for what the author intended, and not limit the whole concept of faith to that one verse. If you'd like to read a fuller definition of the biblical meaning of faith, see this post. But there is one thing you can actually know, and that is that Sam Harris' version of Hebrews 11:1 is nothing but a straw man.

Contempt Prior to Examination is an Intellectual Vice


William Paley on how intellectuals can be biased against evidence:
Contempt prior to examination is an intellectual vice from which the greatest faculties of mind are not free. I know not indeed whether men of the greatest faculties of mind are not the subject to it. Such men feel themselves seated upon an eminence. Looking down from their height upon the follies of mankind, they behold contending tenets wasting their idle strength upon one another, with the common disdain of the absurdity of them all. This habit of thought, however comfortable to the mind which entertains it, or however natural to great parts, is extremely dangerous; and more apt, than almost any other disposition, to produce hasty and contemptuous, and, by consequence, erroneous judgments both of persons and opinions.

Does the authoritative teaching of Christianity stifle reason?


Although G.K. Chesterton wrote Orthodoxy over 100 years ago, it continues to provide prescient, applicable wisdom for us today. At the beginning of chapter three in that book, a chapter entitled "The Suicide of Thought," Chesterton notes how the sages of our modern age trade on poor assumptions.

Concerning the rejection of religious authority, he writes:
Religious authority has often, doubtless, been oppressive or unreasonable; just as every legal system (and especially our present one) has been callous and full of a cruel apathy. It is rational to attack the police; nay, it is glorious. But the modern critics of religious authority are like men who should attack the police without ever having heard of burglars. For there is a great and possible peril to the human mind: a peril as practical as burglary. Against it religious authority was reared, rightly or wrongly, as a barrier. And against it something certainly must be reared as a barrier, if our race is to avoid ruin.

That peril is that the human intellect is free to destroy itself. Just as one generation could prevent the very existence of the next generation, by all entering a monastery or jumping into the sea, so one set of thinkers can in some degree prevent further thinking by teaching the next generation that there is no validity in any human thought. It is idle to talk always of the alternative of reason and faith. Reason is itself a matter of faith. It is an act of faith to assert that our thoughts have any relation to reality at all. If you are merely a sceptic, you must sooner or later ask yourself the question, "Why should anything go right; even observation and deduction? Why should not good logic be as misleading as bad logic? They are both movements in the brain of a bewildered ape?" The young sceptic says, "I have a right to think for myself." But the old sceptic, the complete sceptic, says, "I have no right to think for myself. I have no right to think at all."
Chesterton here asserts that faith is not the enemy of reason, but that reason relies upon faith for its relationship to reality. While skeptics and atheists such as Richard Dawkins and Sam Harris continue to shout that they have claimed the high ground of reason, Chesterton ably shows how those claims crumble, and he does so nearly a century before the New Atheists even made them!

The fact that the man or woman who holds to faith in Christ can truly be considered reasonable is made even more clearly with the release of the book True Reason: Confronting the Irrationality of the New Atheists. I was fortunate enough to have contributed to this volume and I highly recommend it to anyone looking for ways to demonstrate how Christianity is intellectually as well as spiritually satisfying.

Tools for the God-Fearing Mind


Jesus commanded us that we are to love God with all our heart, soul, mind, and strength, but many Christians simply don't know how to love God with their minds. Before we can think rightly about God, we need to learn to think rightly, to think logically. In this talk, Lenny teaches you how you can tell the difference between good arguments and bad ones and how you can offer unbelievers rational, persuasive arguments for your faith.

Can You Get a Something from a Nothing?

In my debate against Richard Carrier, I argued that the beginning of the universe pointed toward the existence of God. I had said, "The most fundamental law of science is 'Out of nothing, nothing comes.' We simply do not see things popping into existence for no reason. Every parent understands this axiom when they find crayon marks on the wall or mud scraped across the floor. A child's response of 'no one did it, it just appeared' would be rightly rejected as silly."


This seems pretty common-sensical to me. One cannot get a something from a nothing. In fact, the word "nothing" can be broken apart to show that it means "no-thing." But Carrier replied to my point with this statement:
Oh yes, "out of nothing, nothing comes" is another one. If there is absolutely nothing, then there are no rules governing what will happen. So the idea that "only nothing can come from nothing" is a rule. That's something; that's not nothing. If you really have absolutely nothing then anything can happen. Nothing governs what's going to happen. If we start with nothing, we have no idea what could occur. As physicists will tell you, like Victor J. Stenger in The Fallacy of Fine Tuning, nothing is inherently unstable. So if we did start the universe with nothing, we could actually expect something to come out of it because the probability of nothing remaining nothing is rather low and because there is nothing governing what will happen.
There are a lot of problems here. First, let's look at what we mean when we use the word "nothing." When I say the universe began to exist, I mean that all matter, energy, space, and time came into being where they had previously not existed at all. In fact, when philosophers talk about the concept of nothing, it is generally understood to mean a state that is devoid of all properties. If there is nothing, then there are no physical things that can act and there are no laws of nature by which the non-existent entities would be able to act.

But Carrier seems confused on this. He first states, "The idea that 'only nothing can come from nothing' is a rule. That's something; that's not nothing." Well, that's not really accurate. The idea isn't a rule, but a description. It is another way of saying there are no laws and nothing upon which actions could even take place. But then, he goes on to say, "If there is absolutely nothing, then there are no rules governing what will happen… If you have absolutely nothing, then anything can happen!" Well, using Richard's own criteria, that would be a rule. That means you haven't started with nothing!

The idea that nothing is inherently unstable is a real science-stopper. Imagine people saying, "Well, I we had nothing and now we have this new chemical because anything can happen!" or "We don't know how that came into existence. It must've simply popped into existence because nothing can produce anything!" This is not a reasonable answer. It sounds more like magic than anything else.

So, I find this response problematic on several levels. First, Carrier argues that nothing is a great way to get something. I think that is a terrible answer and he needs to explain why we should accept it for the beginning of the universe then turn around and reject it for any other scientific question. Secondly, if "out of nothing, nothing comes" is considered something, then 'If you have absolutely nothing, then anything can happen" should also be considered something. As such, Carrier hasn't started with nothing and he needs to explain how his "rule" came into existence.

Separating What's Possible from What's Reasonable

Man: Oh look, this isn't an argument.

Mr. Vibrating: Yes it is.

Man: No it isn't. It's just contradiction.

Mr. Vibrating: No it isn't.

Man: It is!

Mr. Vibrating: It is not.

Man: Look, you just contradicted me.

Mr. Vibrating: I did not.

Man: Oh you did!!

Mr. Vibrating: No, no, no.

Man: You did just then.

Mr. Vibrating: Nonsense!

Man: Oh, this is futile!
I've always been a big Monty Python fan. The Pythons' ability to mix thoughtful, intelligent subjects with all-out silliness has never been matched. One of their most famous sketches is "The Argument Clinic" where a man pays for the service of having an argument. Unfortunately, his results are not what he expected. If you're unfamiliar with the sketch, you can watch it below.

The discipline of apologetics is all about giving reasons for your faith. I've engaged with many people, both in person and online, who are skeptical about the claims of Christianity or the Bible. They demand evidence for things like God's existence or the resurrection of Jesus. They say that "blind faith" should be avoided and reason should hold sway over our beliefs.

In such conversations, I usually agree. Christianity has never promoted a blind faith, but one based on certain evidence. Then, depending on the objection raised, I demonstrate this by explaining the evidence I have for my view. If we're discussing God's existence, for example, I talk about the fact that something cannot come from nothing, that we see clear signs of design in the conditions of the universe, and so on.

Like the man in the Argument Clinic, my reasons have been sometimes met with "but it isn't impossible that the initial conditions of the universe just happened to be set that way" or "it may be the case that the universe came from something else that we don't know" or "it could be possible that certain chemicals came together to form a living organism." Others will respond with claims that although science offers no answers for us now, it will someday; we just need to give it more time.

The problem with such replies is that they are not seeking to answer the question the skeptic originally raised. The person has asked you to defend the reasonableness of your belief. If you can show that your belief is built upon evidence, then you have at least met the initial query. The question now becomes is there any counter-evidence to rebut the evidence you have provided. This is a crucial step. It isn't good enough to say "Well, we don't know what happened so there could be other possibilities." Of course there could, but the burden of proof has just shifted to the one who is dismissing your evidence. He or she must do more than posit "just-so" scenarios.

Just-so scenarios are just that: ideas without any evidence behind them. As such, they put the objector in the very same category as that to which they are objecting: offering a case with nothing to support it. Part of being a rational person is to draw a distinction between what is possible and what is reasonable to believe.

There are a lot of things that may be possible in the world, but are highly unlikely: such as dealing oneself a royal flush in poker two times in a row. Of course mathematics shows that such an event is possible, but it isn't reasonable to believe that such a thing happened without deliberate intervention. If I'm playing poker and I see you dealt two royal flushes, I'm going to accuse you of cheating. That would be the reasonable thing to do. Similarly, seeing the strong evidences for a creator from the natural world, one is reasonable to infer deliberate intervention.

The man in the Argument Clinic sketch recognizes that he is not getting what he paid for. He complains:
Man: An argument isn't just contradiction.

Mr Vibrating: It can be.

Man: No it can't. An argument is a connected series of statements intended to establish a proposition.

Mr Vibrating: No it isn't.

Man: Yes it is! It's not just contradiction.

Mr Vibrating: Look, if I argue with you, I must take up a contrary position.

Man: Yes, but that's not just saying 'No it isn't.'

Mr Vibrating: Yes it is!

Man: No it isn't!

Man: Argument is an intellectual process. Contradiction is just the automatic gainsaying of any statement the other person makes.
"Just-so" responses are really a form of gainsaying. The person is simply dismissing the evidence that you have just presented.  As the man in the sketch said, it isn't an argument, but a childish way to escape the evidence that you may present.

Arguing from Ignorance

After posting my podcast series "Why the Origin of Life Requires a Creator," I received a response from an atheist friend of mine who charged me with committing a logical fallacy. In the comments section he wrote, "It is all a logical fallacy called 'Appeal to Ignorance.' 'Not knowing' isn't evidence for, nor against, the existence of God."


For those who are not familiar with the discipline of logic, there are two types of fallacies one can commit when advancing an argument: one is a formal fallacy, which is when the conclusion one presents doesn't follow from the premises. In casual conversation this sometimes happens, but one is more apt to run into an informal fallacy. An informal fallacy is one where you present something as evidence that really isn't evidence for your conclusion at all.

The fallacy known as appeal to ignorance (formally argumentum ad ignorantiam) was first coined by philosopher John Locke in his Essay Concerning Human Understanding. The Lander University Philosophy Dept. web site gives us a good definition:
  1. Argumentum ad Ignorantiam: (appeal to ignorance) the fallacy that a proposition is true simply on the basis that it has not been proved false or that it is false simply because it has not been proved true. This error in reasoning is often expressed with influential rhetoric.

    The informal structure has two basic patterns:
    • Statement p is unproved.

      Not-p is true.
    • Statement not-p is unproved.

      p is true.
  2. If one argues that God or telepathy, ghosts, or UFO's do not exist because their existence has not been proven beyond a shadow of doubt, then this fallacy occurs.
  3. On the other hand, if one argues that God, telepathy, and so on do exist because their non-existence has not been proved, then one argues fallaciously as well.
Of course, anyone who has listened to the series would know that I don't claim that God exists because no one has proven otherwise. However, I've heard this charge before, that by claiming a creator I am somehow committing an appeal to ignorance. In my conversation, my friend said:
"If caveman are sitting around talking about what causes thunder, and one says it is the gods in the sky fighting, and the other says he doesn't know, does that prove it is the gods fighting (inference to the best conclusion)? We don't know anything about origin details just like the cavemen... running to belief in superstition doesn't equate to discovering truth.

"I agree we should always use 'inference to the best conclusion' but in these categories no one knows. So to claim this as evidence for god is the fallacy of 'appeal to ignorance.' It is a classic example of that basic fallacy."
Notice the equivocation in the example above. The "cavemen" not only know nothing about the origin of lightning, but they also know nothing of the nature or property of lightning. Understanding the nature of a thing can help us to identify or eliminate its origin. Knowing the nature of a thing is real information that must be considered when weighing the cause.

My friend Jim Wallace recently explained to me that a homicide detective, when confronted with a dead body, knows that there are only four explanations for a person's death. The person may have died of natural causes, he may have died from accident, he may have committed suicide, or he may have been a victim of homicide. If there are no witnesses and no recording of the events, the detective doesn't know which scenario is true. However, homicide requires there to be another person present, where the other three causes do not. If you can examine how the person died and show that this person could not have died without the actions of another, then you are reasonable in holding homicide as a viable option.

When arguing with my atheist friend, I used a similar analogy:
"If I were to say 'The origin of a bullet in a man's heart requires a shooter,' would that also be an appeal to ignorance? There's evidence and there is an inference to the best explanation of that evidence. That is not a logical fallacy, but an inductive argument."
You see, we know that bullets don't just grow inside of people. We also know that life requires certain initial conditions. We can understand what replication entails, how DNA to mRNA to amino acid strings to their folding a certain way in order to create required proteins necessary for life. We know about chirality in amino acids and sugars and the long odds of homochirality happening randomly. All of these points I brought up in my series, and they all argue that life simply could not have arisen through only natural processes.

It is easy to throw out the charge of fallacy, such as "you're appealing to ignorance!" but by misusing the term it simply becomes a dodge to avoid the evidence presented. Argumentum ad Ignoraniam takes a very specific form. Don't fall for the charge of committing a fallacy when the fallacy doesn't apply.

There are many of these informal fallacies, and the Internet is awash in lists of them. For those who wish to dig deeper into learning about logic and critical thinking, including identifying fallacies, I recommend The Thinking Toolbox and The Fallacy Detective, both by Nathaniel and Hans Bluedorn.

And in all of your reasoning, "Let's be careful out there."
