How to Share Your Faith Without Using Scarecrows

I've recently written that a major problem I see in discussions of faith is the straw men that are erected by those who would seek to tear down a viewpoint. By creating a flimsy caricature of a belief, it becomes much easier to defeat that caricature than deal with the nuances of the belief itself. This is something that I work hard at avoiding when I discuss a belief different than my own. I absolutely hate the straw man, not only when someone substitutes a flimsy shell for my real belief, but I hate it when I misrepresent someone else's view. It's a form of bearing false witness and if someone values the truth, then straw men have no place in argumentation.

Because Christians and non-Christians are equally prone to commit the straw-man fallacy, I wanted to offer some tips on how to avoid misrepresenting someone else's views. These are pretty simple things to list, but sometimes they take a bit of work which may be why they aren't more frequently implemented. But if you follow these guidelines, you will be more informed and a better person for it.

1. Ask More Questions

I've written on this before, but it bears repeating. Instead of immediately launching onto along, drawn out apologetic against a position that you hear, first find out exactly what the person believes. If you find someone who states they are pro-choice, it's OK to ask "exactly what do you mean when you say 'pro-choice?'" You can then continue to explore their views. Do they believe the government shouldn't regulate any medical procedures? Do they believe that at no time before the birth that a human person exists in the mother's womb? How do they define personhood? By asking these questions, you can get a better picture of that person's particular views and you may find areas where you can point out a contradiction in their thinking.

In conversational first engagement, questions like "What do you mean by that," "Can you explain that more," or "Can you give me an example" are key go knowing just where the other person stands. Use them more often and ask more questions and make fewer statements.

2. Restate the person's position back to him

Once you feel you have understood your interlocutor's point of view, repeat it back to them. Say something like, "If I understand you correctly, you feel that the government should stay out of women's healthcare issues because it interferes with their lives." This approach is what is known as a Socratic dialogue. This approach figures prominently in Plato's writings and was further used effectively by Thomas Aquinas. By repeating the person's arguments back to them and ask if they agree with that summarization, you have paved the way to make a convincing argument without the knee-jerk response of "That's not what I meant!" They have just agreed that you have understood their view; thus you are in a better position to be more persuasive since they agree you understand their reasons well.

3. Get information from the horse's mouth

While inquiring from the person gives you a lot of information about their specific beliefs, I think it's also important to read primary sources from the different faith positions to make sure you understand what the actual belief system entails. In talking with folks, I find that thy really don't even know what their own faith tradition teaches and they believe something different than the official dogma/theology of the faith with whom they identify. This happens often in discussions Mormons and Roman Catholics, but it can even be true with atheists or any other belief system. Therefore, it's good to read the actual publications and pronouncements that are held as authoritative. Talk with a Mormon Bishop or read LDS writings. For the abortion debate, make yourself aware of Margaret Sanger's motives and read NARAL's political stances on things like late-term abortions.

I realize that this kind of research can only happen after you have engages someone in conversation. If you don't know what you will run into, it can be pretty tough to read up on everything. I know very few Christians who have even heard of Vedanta Hinduism, for example. So, you may have to do your research after your initial encounter. However, Mormons, Jehovah's Witnesses, Muslims, and atheists are common enough that you can begin to study their beliefs and doctrines simply to be prepared in case such an encounter arises. If you can master the basic history and concepts of the more common worldviews, then the details offered during discussion will make more sense.

As someone who has been teaching apologetics classes for some ten years, I've covered quite a variety of beliefs. More than once, I've given a presentation on a religious belief system where the people present were either previous adherents or even still practicing adherents. To be told that I was fair in my representation of their view gives my apologetic more weight in their eyes. To erect a straw man is really tantamount to lying about another's belief, and that should never be a part of our witnessing approach.

Why I Am a Christian: Because of the Problem of Evil

Yesterday, I began to explain why I hold to Christianity. Of course, as I've said before, there is only one good reason to believe anything and that is if it's true. I believe Christianity is true and I've been laying out my reasons why Christianity is true. One reason I want to talk about today seems rather backwards. In fact, many will tell you that this particular issue is the toughest challenge to Christianity and a lot of atheists became such because of the problem of evil in the world. But I believe that Christianity is true because of its approach to the problem of evil.

The problem of evil is usually presented like this, "How can an all-powerful, all-loving God exists when there is so much evil in the world?" That seems to be a hard question, and even though the argument fails logically, it intuitively strikes people as an objection needing an answer, and Christianity does offer one. Christianity teaches that God simply isn't done with us yet. God allows evil for certain period of time in order to accomplish the purposes He set out for man and His creation. Once those purposes are complete, He will vanquish all evil. The cross of Christ has guaranteed that Jesus has triumphed over death and sin and the Christian rests assured that evil will not exist for all eternity. In a relatively brief period, God will vanquish all evil yet preserve our freedom to exercise our love towards Him forever.

What other worldview provides a better answer?

The interesting thing in this question, though, is that it isn't incumbent on only the Christian to answer it. Evil is recognizable in any religious system or non-religious system. Every worldview needs to account for the problem of evil; not just Christianity. How do the other belief systems measure up?

When someone offers an objection to God on the basis of the amount of evil in the world, they are conceding at least two things:

1. There is an objective "good" whereby we can measure actions and label them as good or evil.
2. The fact that evil actions exist means there are problems in the world that need to be solved.

Given that those two facts can be established, they open up questions of their own. For the first, one must ask "Where are you getting this idea of good and evil from? Is evil real? If so, what is that objective standard whereby we can measure actions as good or evil?" The next question can then be, "and what is the solution to evil according to your worldview?"

These questions pose significant problems for other worldviews. Atheists, for example, cannot ground their understanding of evil in anything objective. Evil becomes relative to the individual or the community, and therefore true, objective evil cannot really exist. An atheist who claims that the natural world is all there is would say that's just the way the world works. People are born and they die and eventually our sun will be extinguished with no thought at all toward humanity. The result of an atheist worldview is that suffering will never be able to be overcome. Cruelty is woven into the fabric of life and there is no hope of vanquishing it.

Eastern faiths such as Hinduism and Buddhism would provide a different understanding. They hold that the evil we experience is as illusory as our earthy existence. We have forgotten that we are one with the divine and we need to become one again. Only by being liberated from the cycle of life, death, and rebirth through enlightenment can one escape the karma that is responsible for our discomfort. Once this happens, evil will vanish like the illusion it is. The result of this view is that they ignore the reality of evil and ignore the reality of suffering people experience.

Positions taken by other beliefs:

1. Atheism (naturalism): No God exists
   Result: Suffering will never be overcome
2. Pantheism: No evil exists
   Result: Ignoring reality, ignoring suffering
3. Modified theism: God is limited in power and cannot control evil
   Result: A God not in control—ergo no God at all.

Finally, there are faiths that hold that God exists, but evil is something that sits outside His complete control. Rabbi Harold S. Kushner voiced this view in his book When Bad Things Happen to Good People. God is limited in His power so he cannot control all the evil that we see. He can work within the natural order of things, but the conquering of evil is beyond His reach. Such a view robs God of His position as God and is internally incoherent. The result becomes that evil is stronger than God and there is no hope for vanquishing evil.

I've made the claim that Christianity is both internally consistent and externally coherent. It does not contradict itself in its own claims, even though it makes claims about huge concepts like the nature of God, the nature of man, how people work, and the nature of morality. It also helps us make sense of the world and how we experience it. Looking at how other worldviews answer the problem of evil shows that the difficulties their positions create are far greater than the challenge to the Christian. Christianity offers both a compelling understanding of the fact that real evil does exist and it offers the believer the hope that one day that evil will be vanquished.

Why I'm A Christian - Part 1

I've been doing apologetics for nearly 20 years now. In that time, I've had the opportunity to engage in conversation with many who either don't believe in Christianity or don't believe in God at all. There have been a lot of conversations where we've traded various proofs for our point of view, but I cannot point to one extended conversation where someone has asked me, "So tell me, why are you a Christian?"

I've talked before about why it is important to ask people why they believe as they do. It helps you to understand the important things that motivate the person to believe as the do. It also keeps you from constructing straw men, something that everyone should avoid. I stress this because not arguing against a straw man shows that one is really interested in the truth, not merely "winning" some kind of debate contest. But I do find it interesting that in all my engagements with atheists, I simply don't get asked this question.

There was a recent Twitter exchange where I posted a link to the testimony of Matt Walsh. An atheist responded to my tweet and asked, "so why did you end up deciding to believe in the particular deity you did?" Given the way he phrased the question, I had a suspicion that he wasn't truly interested in my story (and the ensuing conversation, which you can read here, proved my suspicions true). My answer was that Christianity was the only faith I've found to be both internally and externally coherent, meaning that it doesn't contradict itself within its own tenets and it matches our experiences with the outside world. So let me now share with you, dear reader, why I am a Christian.

Why I am a Christian - Christianity Meets Natural Expectations

The first reason why I am a Christian is because it is natural to assume that God exists. Children really don't require much teaching to believe in God. They look at the design in nature and they intuitively know that something doesn't come from nothing and design requires a designer. These are usually my first two arguments when I speak to someone about the existence of God, but they only require that level of sophistication when someone is denying either of those points. Because there is something rather than nothing and because the something that we see (creation) shows balance and design, it makes sense to conclude that a mind created it. God fits.

While one may try to argue that there are a lot of gods who create (most religions have some kind of creation story), the fact that the Christian God created the universe out of nothing as opposed to the elements of the universe already existing. The fanciful nature of those myths, such as the Hindu and Chinese creation stories where God springs from an egg to form the universe or the Greek and Babylonian accounts of the elements of creation actually being the ancient gods don't offer an explanation of where these elements came from. They also have a diminished view of deity, as their gods can come into being and cease to be. They simply don't make sense.

Why I am a Christian - The Christian Faith is Rooted in History

Another reason why I am a Christian is because I found that there really was a man named Jesus of Nazareth who really lived some 2,000 years ago. The historical evidence of Jesus' life and ministry is as strong as anything we could hope for from ancient sources. When one views the New Testament documents, it is clearly evident that those who wrote the New Testament lived in the time and place which they are describing. The Bible doesn't read as some far-off, third hand account. It reads like ancient history.  Jesus also had a great impact on not only his immediate followers but his teachings radically changed western society. The proof of Jesus' life is like the proof of a stone thrown into a pond: you may not see the stone, but you can look at the surface of the pond and see the stone's effect. You can know he was real.

The historical aspect of Christianity is not a secondary consideration, but a primary one. From its very beginning, Jesus' disciples pointed to the real events of the resurrection and their eyewitness testimony. Paul tells the Corinthian church that the resurrection must be historical or their faith is worthless and he points to eyewitnesses. History and multiple people attesting to the facts surrounding the origin of Christianity are crucial to its very existence. Therefore, Christianity isn't merely a "take it by faith" type of belief system, but one that is rooted in an historical event: the resurrection of Jesus of Nazareth.

Tomorrow, I will continue to offer my reasons as to why I am a Christian, but for now, I hope you'll consider these points. Any belief system needs to correspond to itself, that is it should be internally consistent, and it needs to clarify what we experience in life. I think Christianity does both.

Beware of Straw Men!

In the movie The Wizard of Oz, Ray Bolger was originally cast to play the part of the Tin Man instead of the Scarecrow. According to Wikipedia, he longed for the part, though. Luckily, he was recast as the straw-filled character movie audiences have come to know and love. Bolger's character is someone you would want to embrace, a true friend who can sing and dance his way into your heart.

However, many times I find people much too easily embracing another type of straw man, one that should be avoided at all costs. I'm referring to the straw man constructed by those arguing for one particular position over another. I've discussed some of the different ways to argue about a position. I don't mean a fight, but the rational exchange of ideas. Sometimes when building their argument, people make mistakes. These are known in logic as fallacies and the straw man is a classic fallacy. Basically, one constructs a straw man when they argue against a position that the other person doesn't hold, or they mischaracterize the other person's position. Usually, this kind of mischaracterization is used so that, like a straw-filled sparring dummy, the person's argument is easier to knock down.

Examples of Straw-Man Arguments

Some examples of straw-man arguments are easy to see. In their book The Fallacy Detective, Nathaniel and Hans Bluedorn use the following example of a straw man:

POLITICAL CANDIDATE A: Due to this year's budget problems, I think our state should decrease the amount of money going to the schools. This would solve the problem. We could bring the amount of money back to normal next year.

POLITICAL CANDIDATE B: My fellow citizens, is this what you want in a candidate? Someone who is against our schools, against our children's education, and against our futures?

As you can see, Candidate B does not talk about the question that Candidate A is focusing on: solutions to a budget problem. Instead, Candidate B misrepresents Candidate A's position to make it sound as if he is seeking to cut school funding because he doesn't want schools to succeed. It's much easier to win an argument in the minds of the people when you create a faulty position and then turn around and argue against a position that the other person never took. That's why the Bluedorns classify a straw man as an attempt to avoid the real question.

When defending one's faith, this kind of switch happens far too frequently. Here are some classic examples:

CHRISTIAN: Without a wholly good God, there is no way to ground moral values. Therefore atheism cannot hold to objective morality.

ATHEIST: How dare you Christians say that because I'm an atheist I cannot understand what it means to be moral!

In the above exchange, you can see that the Christian wasn't discussing whether the atheist could recognize or comprehend what it means to be moral. That's a knowledge question. Rather, he was making the claim that there is no logical basis for believing such morals, even though they are recognized, should carry authority over someone's actions. This is known as the moral grounding problem.

ATHEIST: Science is based on reason while religion is only based on faith.

In such a statement, there are really two straw men. The one easier to identify is that religion (usually meaning Christianity) is only based on faith. This simply isn't true as Christianity from its very beginnings have relied on the evidence of the eyewitnesses and the empty tomb (ref Acts 2:32, Acts 3:15, 1 Cor 15:3-8). Even so far as appeal to the crowd with phrases such as "as you yourselves know."

Secondly, the statement mischaracterizes science as somehow being completely devoid of passion or bias. The history of science argues otherwise, with huge fights breaking out over various positions. Because money and position are now a part of the scientific process (most on the university campus has heard the canard "publish or perish") it is easier for people to inadvertently become biased in their research. In fact, that's what this recent article in the science journal Nature warns. They noted within the field of pharmaceutical development "Science's internal controls on bias were failing, and bias and error were trending in the same direction — towards the pervasive over-selection and over-reporting of false positive results." This doesn't mean that every scientific discovery is biased, but it does demonstrate that science is not somehow immune from bias any more than any other field of study.

Imposing a straw-man fallacy during an argument is not playing fair. It judges another person for a view that he or she doesn't hold and then pretends to make the perpetrators seem more intelligent than they are. If we are going to engage others, we must make sure that we properly understand their specific position. Tomorrow I will talk more about that.

An Untangled Problem for Evolution: DNA Topoisomerase.

Background

DNA replicates itself. That is Biology 101. The process is quite complex and any biology student required to rattle off the procedure on an exam can confirm. Although there are separate kinds of topoisomerase,1 they perform the same essential function within the process of replication.

What is topoisomerase?

In each human cell, there are approximately 2 meters of DNA compacted within a nucleus of the diameter of about 10 micrometers.2 For perspective, imagine that the nucleus is represented by a standard basketball. The length of all the DNA compacted into the ball would go round-trip between the earth and the moon just shy of twice. Topoisomerase has the job of ensuring that the shape of DNA is manageable. Add in the fact that DNA is not just a helix, but a double-helix. As one might imagine, the task of trying to do anything productive with this material presents very serious concerns that need to be dealt with. During replication, the topology (i.e. the shape and structure) of DNA and the movement in unzipping result in issues like tangling and kinking, so the process faces a formidable and complex challenge of bioengineering.3 It’s topoisomerase’s job to alleviate those issues so they don’t halt the replication process.4 If DNA cannot replicate, then an organism cannot grow. Additionally, DNA doesn’t just unzip for replication. It unzips in a process called transcription, which, with the help of RNA, is the first half of producing vital proteins in the cell.

Two examples might help illustrate some of the mechanical concerns that arise. Without even trying, the ordinary use of a wired phone produces coiling in the helical cord. No extraordinary spinning or energy is required to produce the effect, but it doesn’t take long for the cable to go from fresh and neat to knotted spaghetti, which seem to never come out. Even if the tangle is gone, there always seems to be a small bend or a missing turn were the tangle was. The second illustration may serve to demonstrate the problem of kinking just prior to cutting the DNA strand in two. To demonstrate the concept, you can take a piece of twine and try to unwind it by pulling away both its twisted strands away from each other. A "Y"-shape forms: the two strands being pulled apart are each the top segments of the "Y" and the rest of the twine is the bottom. Now at some point, enough tension will build up at the center of the "Y" to where you can no longer pull the strands apart. Fortunately, topoisomerase is there to work out these sorts of problems. Its process is so vital and complex that some have referred to topoisomerase as the "magicians of the DNA world"5 because of their uncanny ability to manipulate the DNA strand and master its topology. 

The Problems for evolution

1: Does not fit early evolutionary models for an ancestral topoisomerase

It is still unclear how exactly topoisomerase originated on an evolutionary model, particularly because all the different types of topoisomerase appear to have originated independently of one another.6 A core tenet of evolutionary biology is that all life can be traced to a common ancestor (more technically, LUCA: last universal common ancestor). It is natural to assume that LUCA would have some master topoisomerase that would have developed into the varying domains7 of natural life: Achaea, Bacteria, and Eukaryota. But, this seems to be an incorrect inference that does not align with the actual data.8  It is speculated that topoisomerase might have emerged with either an ancient viral lineage or a LUCA that began with RNA genetic information or a combination of the two.9

These RNA-infused models would be controversial, because such scenarios involve the already contested10 (among researchers in that field) RNA-world hypothesis for the origin of life. And, the progressive introduction of topoisomerase and other necessary replication proteins into the evolutionary lineup seems an inventive proposition, but requires massive amounts of biological informational leaps that are unfounded, especially within the limited time window for the emergence of life on earth that evolution demands. 

2: Conceptual Paradox11

Most of all, the origin of topoisomerase presents a chick-and-egg paradox. To replicate itself the DNA molecule needs topoisomerase to unwind it. And, DNA would need to code for a protein to do the unwinding (in order to pass on the genes to code for topoisomerase). It’s like having a car with no gas. You need to drive to the gas station to get gas, but you need gas to get to the gas station. DNA might have obtained topoisomerase from somewhere else, but the instant it makes a copy of itself, the other strand needs topoisomerase also. The scenario requires the leap to the reality, where DNA actually codes for this protein itself. That is not to mention that the actual mechanics of unwinding get even more complicated, because topoisomerase is able to cut and re-join small sections of DNA, which require precise biochemistry to ensure the right pieces get linked back up with each other and at the proper speed. Too slow, and the DNA doesn’t unwind fast enough for cell division (mitosis) and the cell dies before replication can occur.12 Too quickly, and the cell can set off its own self-destruct sequence (apoptosis) or cause irreversible damage to the genes that results in cancer.13

Conclusion

Lastly, it is also important to keep in mind that this is only a piece of a wider issue for evolutionary biology to explain DNA replication in general: proteins that function as stabilizing clamps, ones that actually unzip the DNA strand, others that error-check the new copies, or the fact that one side of the DNA is duplicated backwards and in sections…
