Where Do Christians Get Their Morality?

Where Do Christians Get Their Morality?

Ask a random Christian where his morality comes from, and you are likely to get one answer out of a few that are commonly given. Many fundamentalists believe that God is the source of all morality. Without God, they say, humans would not know right from wrong, and we would be living in total moral chaos. More moderate Christians often offer a more deistic explanation. God created humans with an innate sense of right and wrong, and even without his direct intervention, we know what we ought to do because he has placed his moral laws in our hearts.

Some Christians believe that morality is absolute. There are things that are always wrong, and things that are always right. The ends do not justify the means in any case, and we ought to trust God to work things out when it appears that we are doing something harmful by “doing the right thing.” Even outside of Christianity, there is a prevalent belief that morality exists on some kind of higher philosophical plane, and that it is proof of humanity's separation from the animal world. We are different in kind from the animals because we have morality.

I'd like to examine these claims in light of both philosophy and science to see if any of them hold any water. In the end, I hope to convince you that not only do Christians not have any means to derive a system of morality from their faith, they have every justification in the world to act immorally with impunity based only on their personal goals.

Morality Comes From God

Let us suppose that God is the source of all morality. For now, we will take the most extreme Christian view – that morality is impossible to derive from human wisdom, and that we must rely solely on the word of God to know what is right and what is wrong. If this is true, then it must be true that there is no logical reason to do what is right other than fear of God's punishment or desire for God's reward. If this conclusion seems odd, just consider the alternative. If we can think of any reason to do the morally correct thing, then we are basing morality on something natural. If it is right for me to feed my infant child because otherwise the child will die and that would cause me grief, then there is a natural reason for me to feed my infant child.

It doesn't take much thought to realize that morality doesn't derive solely from God. Virtually every day of our lives, we are faced with moral choices, and we reason out the best course of action. Our thought processes involve causes and effects, not calling to memory a set prescription from the Bible. It should be painfully obvious that if morality does indeed come from God, it is not solely dependent on arbitrary dicta. There are unmistakable real world consequences to our actions, and we can judge their relative value based on individual situations.

For emphasis, let's think of it another way. If God truly was the only source of morality in existence, then we should not be able to distinguish right from wrong except when it was specifically mentioned by God himself. When presented with a unique moral dilemma, we should be at a complete loss for any means of deriving the correct answer. This is obviously not so. As human civilization has advanced and technology has increased, we have created moral dilemmas that couldn't have been conceived when the Bible was written. In many cases, we have established very clear ideas of what is right and what is wrong.

There is only one thing we can do if we are to save the idea that God is the source of morality. We must admit that God has instilled in humans a conscience, and that man is able to reason out morality on his own without reference to an arbitrary set of rules. This is the position that most reasonably intelligent Christians take, for the simple reason that the exercise of a modicum of intelligence pretty much necessitates it.

Unfortunately, this position fails on several levels, although the failures are more subtle, and take a little more critical thinking. Straight out of the gate, we must ask a crucial question. If God has instilled in humans the ability to judge right from wrong, what is the Bible good for? This question isn't as flippant as it may appear. Pastors all over the world thump the Bible on their podiums while decrying Godless heathens who don't act as it dictates. In heated debates over moral hot button issues, the Bible is used as a final arbiter. God says it. I believe it. That settles it. Anytime the Bible disagrees with our innate sense of morality, we ought to believe the Bible over our own conscience.

We are forced now to ask the question. What is the final arbiter of human morality? Is it God's word or our conscience? If it is God's word, then we are headed back towards where we started, only now we are in a worse position. We've admitted that our conscience is a real, God-given tool for determining the morality of a given situation, but now we're also admitting that God's word trumps our conscience. This is another way of saying that when God wants us to do something, it is good, regardless of what our conscience says.

While many Christians would happily agree with this statement, it leaves us with a horrible dilemma. There are, at present, somewhere in the neighborhood of fifteen thousand denominations of Christianity, worldwide. Each one of them has different views on morality, ranging from the insignificant to issues of global human existence. We have two choices. Either there is one correct version of Christianity or there are multiple correct versions. If there is only one correct version, how are we supposed to identify it? Every denomination claims that it is the correct one (or at the very least, that it is one of the correct ones!) so we can't rely on these claims to make our decisions. Each denomination interprets the Absolutely True Word of God Which Trumps Conscience in a way that makes sense to them.

Let me reiterate that last sentence, because it's really important. Every denomination that believes the Bible trumps our conscience interprets the Bible in a way that makes sense to them. Did you catch the trap in this sentence? They use their conscience to decide which interpretation of the Bible trumps the conscience! Again, we are faced with a nasty choice. Either there is a correct version of the Bible that doesn't rely on conscience or logic to find, or we are right back to conscience and logic being the ultimate guide for morality.

If we assume that there is, in fact, a perfect interpretation of the Bible, we are at something of an impasse. Since logic and conscience can't be our criteria for making the decision, we must rely on something else, but what? Divine revelation? Again, every denomination makes some claim of divine revelation, so which one is correct? How will we decide? What if none of them are correct? What if, after reading the Bible, you come to the conclusion that everybody's got it wrong, and that you have the perfect interpretation. God has spoken directly to you, and you are certain you are correct. This is fine for you, but how am I to judge whether or not I believe you? You are now in exactly the same situation as the other fifteen thousand denominations. You must ask people to use either logic, conscience, or divine revelation to decide to believe you.

The sad truth is that if there is a true interpretation of the Bible that does not rely on human logic or conscience, then it is unknowable beyond individual interpretation, which is the same as saying that it's entirely subjective.

Did you catch that last sentence? If the Christians are right, then morality is completely subjective. What is it that Christians always say about atheists? Aren't they the ones who accuse atheists of having no basis for morality? According to them, the world would be ruled by anarchy and there would be no way to know right from wrong. Civilization would descend into self serving madness. The irony is that their very own doctrine, if true, leads inevitably to the very state they attribute to naturalism!

Now, we must backtrack. We have reached an absurd conclusion when we followed one line of reasoning. The other line must now be scrutinized. Since it is not possible that there is one correct version of Christianity, perhaps there are multiple correct versions. Again, we're faced with choices. Perhaps there are some things that are universally right and wrong, and some that are malleable according to individual situations. The other option is that all things are malleable and based on specific circumstances.

If we accept the former option, we are immediately forced to address the question of which things are universals, and which are subjective. Unfortunately, this is no easier than the dilemma we faced earlier. Either logic and reason can tell us the answer, or it must be found in the Bible, or through divine revelation. If it is found in the Bible, then where is it? Having read the bible myself, I can recall no such clear cut explanations of morality. Instead, I remember reading contradictory edicts from God himself. Don't kill, unless God orders you to, or if it's lawful to kill. Then again, turn the other cheek and repay evil with kindness. Then again, Jesus came to uphold the law. Then again, Jesus came to repeal the law. Then again, it is better to kill yourself than to cause a child to stray. Then again, suicide is an unpardonable sin. Then again, and again, and again, and again.¹

The latter option leaves us in a real pickle. If all things are malleable and based on specific circumstances, then the only conclusion is that there is nothing that is set in stone. There are no absolutes, and God's word is not the final arbiter over conscience. With no instance by instance definitive statement from God himself, there is no way to ascribe any absoluteness to any moral imperative, and we clearly have no such step by step guide.

If there are no absolutes, and God's word is not the final judge of what is moral and immoral, how is a Christian to judge right from wrong? At the risk of becoming pedantic, I'm afraid I must point out that there are two choices. Either the Christian can continue to use the Bible, or church doctrine, or some other source as a basis for morality, or they can admit that morality is ultimately judged by humans on a case to case basis, without any arbitrary intervention by God.

If some theist source is used, then the Christian is right back where we ended up earlier – arbitrary subjective morality. If it is admitted that morality is ultimately judged by humans, we have relegated God to irrelevance. Whether or not God created man with a conscience or the conscience evolved is a pointless distinction. If the conscience, or logic, or any other natural method is used to determine morality, then man can determine morality without God. The foundation of one of religion's most ardent claims collapses. Man does not need God to live morally.

Morality By Plato

Having extracted God from the process of arbitrating morality, we must now address the question of morality as an absolute. Is there some kind of platonic model of morality that is universal to all humans? Are some things absolutely right and some absolutely wrong, or is morality subjective and arbitrary? Perhaps God created man and instilled in him an instinctive knowledge of the perfect good, much like Plato's perfect conceptualizations of imperfect reality. If this is true, perhaps humans are always striving towards perfection but always falling short. Maybe this is the true nature of the biblical “Fall of Man.” In fact, maybe this is the difference between Christians and non-Christians. Maybe God gives Christians an extra “morality boost” and allows them to see a clearer image of the cave wall.

As we did with all the previous claims, lets assume this to be true and see where it leads us. Let us suppose that for every human interaction conceivable, there is a “perfect” morally good action for every individual to take. The first question we must ask is what scale is being used to judge perfection. Is perfection based on the greatest good for the greatest number of people? What about reduction of suffering? Perhaps equality is the ultimate measure. (But, if it is equality, in what sense do we mean equal? Equality of opportunity, or resources, or happiness, or what?) To say that there is a perfect morality is to admit to a scale. Perfect must be judged in relation to something, or the word has no meaning.

Perhaps now is a good time to explore a hypothetical situation to see if we can gain some real world insight into the possibility that there is such a thing as perfect morality. Suppose that there is a man who has a wife and family. He has a good job, with enough time to spend with his children and his wife, enough free time to avoid getting overworked, and enough money to pay all the bills. (Talk about a hypothetical situation!) One day, this man discovers that his boss is involved in a large scale fraud that, if allowed to continue, will cheat hundreds of thousands of people out of large amounts of money. Unfortunately, the fraud is so pervasive throughout the company that if the whistle is blown, the company will surely fail, and all the employees will not only lose their jobs, but many of them will be pulled into years of lawsuits, whether they were knowingly involved or not.

If you are like most people, you have decided that despite the personal loss and the potential problems for other employees, the only moral thing for the man to do is blow the whistle on his company. There are other jobs, and it's selfish of him to hold onto his perfect little life knowing that it will cause great harm to so many people. Furthermore, “shit happens,” as the saying goes, and it's unfortunate that many of the employees will be caught in the mess, but it's just a case of bad luck. It can't be helped.

Does this situation tell us anything about the concept of perfect morality? Let's look at it from the perspective of the greater good. It is true that more people will be helped by blowing the whistle than not. In terms of financial success, the greater good will be served. However, in order to achieve the greater good, there must be lesser bad. Some people, including the whistle blower, will have to suffer financially. Where there is financial gain, there is also financial loss.

Mathematically, there is almost certainly an optimum financial solution to this problem. Perhaps there is a course of action that could minimize financial losses to employees as much as mathematically possible while maximizing the financial gain of those who will benefit from having the fraud exposed. We can say that in terms of financial good, there is a perfect solution to this problem. Maybe it involves a different employee blowing the whistle, or the boss having a fit of conscience and admitting his fraud. What the action is is irrelevant. The broader point is that there is a perfect solution.

Unfortunately, it's not as simple as that. When I began discussing the greater good, I assumed that good to be financial. If we use another measure, we might find completely different results from taking the “perfect” moral action. Supposing that the fraud comes to an end in the best possible way financially, what can we say about the solution based on equality? For instance, if the investors who were going to be defrauded were all upper class and wealthy, the huge financial losses they would take might lower their status to upper middle class, where they would still be quite comfortable. On the other hand, the employees of the company might all be in the lower middle class, and the setbacks from losing their jobs might throw them squarely into poverty, even though the financial losses were minimized as much as possible.

If this were the case, could we then say that a greater good had been achieved? What if there were a total of five hundred children of employees, and as a result of their parents losing their jobs, four hundred of them ended up having to go to lesser schools with poor standards? Knowing that these children will grow up and have children of their own, and knowing that poverty tends to breed more poverty, can we really say that blowing the whistle accomplished a greater good?

We haven't even begun to look at the measures of individual happiness or minimization of suffering. I'm sure there are at least a dozen other measures by which a moral action can be judged, and it's entirely likely that in this very situation, each measure comes out differently on the grand scale of moral correctness.

Even so, our idea of platonic morality is not dead. Perhaps there is a set number of measures by which morality can be judged, and in any given situation, there is an action which is the perfect balance of all of the measures, such that there is no way for a better outcome. To help you think of this concept more clearly, let's say that there are one hundred moral measures, and let us assign a value of zero to one hundred for each of them in any given situation. It's patently obvious that very few, if any, situations will allow an outcome of one hundred one hundreds. Every dilemma will have a number of solutions, each of which is better by some measures and worse by others.

If this is true, then we're left with a puzzle. How do we decide which way to weight the scale? In other words, do we always pick the solution that has the highest aggregate score – the highest total number when we add up the score from all hundred measures? If that's true, what if the solution to a particular problem includes a zero (meaning morally awful) in the category of “Preserving Human Life”? Do we weight “Preserving Human Life” more than “Promoting Individual Happiness”? If so, how do we determine the system by which we will achieve our perfect mathematical formula?

By now, it should be painfully obvious that there is a problem with the notion of Platonic moral perfection. The fact of the matter is that different people have different goals, and different needs, and when morality involves multiple people (as it almost always does) what's good for one person will be less good for another, and with no way to say definitively which person should take precedence, most moral decisions will be ambiguous in some sense.

The Danger of Christian Morality

Before we explore what science says about human morality, I want to take a slight detour and explore some of the consequences of morality as described by Christians. The main point I wish to hammer home is that not only is the Christian model of morality wrong, it is decidedly harmful as well. Imagine a discussion with a believer that goes something like this:

Skeptic: Is it wrong to kill your own child?

Believer: Yes.

Skeptic: Is it always wrong?

Believer: Yes. God has told us that we shall not kill.

Skeptic: And this is absolute and universal. There is never any time when it is ok to kill your child?

Believer: (feeling a little twitchy... he suspects a trap.) Well, I suppose there are some instances. (Perhaps he remembers that God, in the Old Testament, demanded that disobedient children be stoned to death.) But except for really extraordinary circumstances, it's wrong.

Skeptic: What if God told you to do it?

Believer: (Squirming noticeably in his seat.) God wouldn't do that.

Skeptic: How do you know? He ordered people in the Old Testament to do it. He ordered Abraham to do it. Can God do anything he wants to do?

Believer: Erm... well... yes, he can, but he wouldn't.

Skeptic: Well, you believe that he wouldn't, but by your own admission, and by the words of the Holy Scriptures themselves, God has done it, and could very well do it again if it pleases him to do so. Stop squirming around this, and just answer the question. If God told you to kill your child, and you knew with 100% certainty that it was God telling you, would it be a good thing to kill your child?

Believer: Um... well... I don't know if it would be good, exactly, but it would be God's will, so um...

Skeptic: Wait a minute. You're saying that God's will can be evil?

Believer: No, that's not what I said. I just said it wasn't good.

Skeptic: So, it's neutral? There are only three choices, right? Good, bad and neutral. Which is it?

Believer: Well, um... I don't know, exactly...

Skeptic: Ok. Let's get down to brass tacks. If you knew for certain that God wanted you to kill your own child, would you do it?

Believer: (scurries out of the room, making signs of the cross and genuflecting furiously)

From this little discussion, we can see that not only do Christians have nothing solid on which to hang their moral hats, they actually have a very dangerous excuse for doing vicious and horrible things and calling them good, or at worst, neutral. A brief look through history (some of it not particularly far in the past) we see many examples of people doing horrible things in the name of religion and calling them good. I'm not suggesting that every evil act ever committed by a Christian has been because of this kind of justification, but surely there have been many people who have used it.

Lest I be accused of creating a strawman, I want to be clear on one thing. I'm not suggesting that people would not do evil except for Christianity, or that non-Christians haven't done very horrible things. However, I want to make it perfectly clear that the Christian version of morality gives implicit and explicit permission for people to do evil and call it good. While it's true that removing this system of morality from the public consciousness wouldn't eradicate all evil in the world, it would most certainly eradicate some, and that, to me, seems a worthwhile endeavor.² In the words of the Nobel Prize winning physicist (and descendant of a holocaust survivor) Steven Weinberg, "With or without religion, good people can behave well and bad people can do evil; but for good people to do evil—that takes religion."

As I have hopefully made crystal clear, there simply is no basis for morality from God or scripture. At best we are left with a hopeless subjective conundrum and at worst, we have an excuse to do things that all sane people know to be wrong.  Now that we have exposed Christian morality for what it really is, we can begin to delve into the questions from a more reasonable perspective. What does science say about morality? For that matter, what exactly is morality? If morality is not absolute, what is it? If it's not completely subjective, how do we decide what is right and what is wrong?

These questions do not always have easy answers, but they do have answers. Again, we're going to need to learn some real science and be prepared to face whatever answers we find, even if they don't line up with what we were taught as children.

1When faced with this fact, many Christians fall back to the assertion that careful reading of the Bible with an open and honest heart will reveal the “true” intent of the author. Of course, this fails for the same reason that all claims of revelation fail. They are necessarily subjective!

2I should mention the other side of the Christian morality argument. It is often suggested that despite the problems with Christians sometimes doing evil in the name of God, Christianity encourages people to do good that they would not ordinarily do.  It's not within the scope of this entry, but evolutionary psychology explains quite parsimoniously that this notion is bunk.  People of all religions (and non-religions) have always been inspired to acts of charity.   It is just divisive and exclusionary thinking to suggest otherwise.

Three short examples of equivocation

Several conversations recently have given me pause to think about equivocations.  That is, arguments in which a word has multiple interchangable definitions.  Theist arguments are full of equivocations, but I'd like to highlight a few that I've been dealing with lately, and one from the news:

Death:  Back before we knew about neurons and electricity, we were still keenly aware of death.   When a person no longer has the thump-thump in their chest, and they're no longer breathing, they're dead.  Once they're dead, they don't come back unless there's a miracle.  (More on miracles in a second.)

As we became more and more aware of the science behind life, and consequently the science of death, we learned that we weren't necessarily a hundred percent correct about that whole "heart stopped, therefore dead" thing.  In fact, once we discovered electricity, we learned that people can sometimes be revived once their heart has stopped.  We also learned that sometimes, artificially breathing for someone who can't breathe on their own can get them breathing again.

In what I consider one of the worst linguistic gaffes of history, doctors and scientists invented two categories of death:  Clinical death and brain death.  Clinical death is usually caused by cardiac arrest, and is basically what we've always thought of as being dead -- heart stopped, no breathing.  (Apologies to the medical community.  I'm keeping this simple.)  Clinical death isn't always permanent.  Brain death, on the other hand, is when there is no more brain activity.  Once the brain dies, there is no coming back.

So, the word "death" really means two things now.  First, it means "really close to being gone forever."  Second, it means "gone forever."

Here's a really important point:  There is not one case in the history of mankind of someone coming back from brain death.  It's permanent.  Anyone who has ever "come back from the dead" has actually been revived from near death.

I wish scientists and doctors had just invented a new word.  Death would still mean "gone forever" and we would have another word for "mostly dead" (to quote Miracle Max).  If that had happened, we wouldn't have all these silly theists prattling on about how their Uncle Bob was "dead on the table" and Jesus brought him back to life just like he did Lazarus.

Nobody comes back from the dead, folks.

Man Needs God

We hear all the time that man "needs" god, but again, there are two words at work here.  There's a strong and a weak sense of "need."  The strong one is that without a certain thing, a man will die.  Man needs air.  Man needs food.  You put a thousand men into the vacuum of space for ten minutes each and you'll have a thousand dead men no matter how many times you run the experiment.  Man needs air pressure.  This is the strong sense of need.

Sometimes, after arguing with theists all day, I feel like I need a drink.  This is not the same sense of the word.  In reality, if I don't get a drink, I'll wake up fine tomorrow morning, and in fact, I'll probably feel a little better than if I did drink.  Humans feel like they need someone to love them right now.  They need a sense of fulfillment in their jobs.  The list can go on ad nauseum.

Hopefully you see the difference.  One of these words means "a strong desire" and the other means "a necessity for life itself."  Theists use these words interchangably.  In church, they're happy to assert that morality, or happiness, or life itself is fully dependent on God.  We need God for all of it.  The arguments tend to get really silly once an atheist points out that he's happy and moral, but that's not what I want to go into right now.  The point I'm making is that if we had two separate words for "need," these arguments would be dealt with a lot faster.

If theists want to say that a lot of men "really strongly desire" God to be the source of morality, I will concede the point happily and we can both go on our merry way.   If they suggest that without God, it is impossible for me to be happy... well... they'll just look stupid because... um... I'm happy.  Q.E.D.

Finally, a little bit from the news:

This is being called a miracle.  A plane crashed into the icy waters of the Hudson River, and nobody was killed.  People are thanking God for ruining their trip without killing them.

So, you should be getting the hang of this by now.  There are two meanings of the word "miracle."  First, a miracle is something that is highly improbable but clearly possible.  The Miracle Mets were not defying the physical laws of the universe when they beat the Baltimore Orioles in the 1969 World Series.  They were defying odds.  Similarly, when a plane crashes and nobody dies, it's not a physical impossibility that somehow managed to happen anyway.  It's a remarkable coincidence.  It's odds-defying, not physics-defying.

Still, theists are fond of using the word miracle to mean both "things that defy the laws of the universe" and "things that are highly improbable."  We can end this discussion of miracles really simply.  There has never in the history of the world been a documented phenomenon that could only have happened if the laws of the universe were broken.   What we might call "minor miracles" -- things that defy odds -- happen all the time.  That's because when we put billions of people into situations where odds-defying things can happen, it becomes pretty much inevitable that things with less than billion to one odds will occasionally happen.

So, to summarize my thoughts for today:

1) Nobody has ever come back from the dead.  Period.

2) Man clearly doesn't "need" God.

3) God didn't ruin your holiday just to prove he loves you.

On Science and Knowledge, Part I

I have often mentioned the subtle danger inherent in toleration of moderate religion. In short, the most insidious aspect of moderate religion is that it not only permits, but encourages, belief in things which are not supported by evidence. At first, this may not seem like such a bad thing. Many cultural traditions involve harmless (and even fun) promotion of things that are not “scientific.” There are probably hundreds of thousands of people who look back at their childhood years with fondness, remembering the excitement they felt at the thought of a midnight visit from Santa Claus. Millions of people worldwide check their daily horoscope, and they live perfectly functional lives. Despite cases like this, I believe it's crucially necessary to draw a cultural divide between that which is credible, and that which is mythical.

Before making my case, it is important for me to mention that I am not advocating a world without imagination, nor am I suggesting that we all live in a cold, calculating world of probability and detached analysis. In fact, what I'm proposing is the exact opposite in many ways. Even so, my critics will surely play the standard card, accusing me of attempting to rob their lives of any meaning or joy. Of course, the final judgment is to be made by you, the reader, but it is important to me that you understand my intentions at the beginning so that perhaps, if you are prone to making such accusations, you will suspend sentence until you have absorbed my entire argument.

What is Science?

The first step in dismantling the power of religion is to establish the power of science. There are many misconceptions, particularly in America, about not only what science is, but what it can do, and why it is certainly reliable. There is a perceived battle between science and religion, and much to the chagrin of the religious, the whole thing is a sham. The war has long since been won, and much like the stereotypical southern Good Ol' Boy with a confederate flag on the back window of his pick-up truck, many a religious man persists in believing that there is still something to fight over.

Science, very simply, is a process. It is a method, like math or logic. More precisely, it is the method for learning about our universe. Contrary to popular belief, it is not the sole milieu of trained academics and stodgy old men with glasses. Science is practiced by everyone on the planet on a daily basis. In fact – and this is a crucial point – it is impossible to avoid using science.

A simple way to learn the scientific method is to perform a series of thought experiments. Let's start at the very beginning. Imagine that you are walking along a road, and you spot an object on the sidewalk. It is metallic, roughly circular, and covered with a sticky black substance. Now suppose you decide that you want to know what it is. The first thing you are likely to do is pick it up. Imagine that when you do, you discover that it is very hot – so hot, in fact, that you are unable to hold it for very long. Out of sheer reflex, you drop it again.

At this point, we have quite a bit of data to work with. First, we have a physical description of the thing, and we have verified, as well as possible, that our eyes reported approximately accurate information to our brain. From picking the object up, we've learned that the object feels like it looks. It does indeed feel metallic. It has a heft that we would expect from metal. In short, we now have corroborating evidence – feel and touch – to help us decide what it might be.

If you will forgive the pedantic nature of this next observation, I promise it will be worthwhile. Picking the object up is a very important step in our little science experiment. We have all learned that our eyes are often not reliable sources of information. Not only are they often fooled, but many substances look very much like other substances, even though they are quite different. We might very well have discovered that the object, which gave every appearance of being metallic, was actually styrofoam covered with metallic paint. The simple act of verifying our initial observation with a second kind of observation is crucial to science.

Now, after you have dropped the very hot object, you make a third observation. When you put your fingers near your face, you notice a distinct smell that you recognize as that of burning motor oil. This new data puts an idea into your head. Perhaps this object is part of a car, and has recently been expelled from a running engine, landing on the sidewalk only a few moments earlier. In support of this idea, we have the following set of data:

• Metallic object

• Much hotter than expected from the current weather

• Appears to be mechanically crafted

• Appears to be covered with oil

• Found very near a road

  
  

By itself, any one of these pieces of data might not be enough to reasonably conclude that the object is a car part, or that it was recently in a running car. However, when you put all of the information together, it seems a reasonable conclusion. Now, suppose that as you look up, you see a disabled car about fifty feet ahead, and a man working under the hood. At this point, you will probably feel confident enough to take the object to the man, certain that you have found something he needs. If, having done so, you watch him place the object back into his engine, in a space that appears specifically designed for it, you can leave satisfied of the facts.

Removing the details, what can we say has happened here in terms of general principles? First, you encountered something unknown. Second, you made multiple observations. Third, you tested the observations against one another for consistency. Fourth, you made a guess, based on your observations, about a likely explanation for the unknown object. Finally, you devised a test to determine if your guess was correct.

This, in a nutshell, is the scientific method. There's nothing magical about it, and certainly nothing requiring years of education. In fact, without consciously thinking about it, you performed the steps in exactly the correct order! The reason for this is that the correct order is the order that works and you intuitively knew it.

For comparison, let's try thinking of ways in which you could have deviated from the scientific method and reasonably hoped to get the correct answer. Is there any way that you could have looked at the object without recording the observation as data in your brain? Unlikely, to be sure. Could you pick it up without noticing the texture, temperature, or weight? Again, no. In short, there's no way to avoid recording empirical data about the world. Simply by interacting with the world, we are collecting evidence.

Likewise, if a pattern emerges from your observations, it is entirely unreasonable to suggest that our brain will not try to subconsciously make sense of it. That's what brains do. The process of forming guesses about patterns is ingrained in our consciousness, and cannot be avoided. It is the way we think. Literally. 

Very simply, the scientific method is just the expression of what we as humans unavoidably do. We make observations and predictions based on patterns of information. Now, let us do another thought experiment about the same situation. Suppose that after having gathered all your data about the mystery object, you decided that the object was likely a piece of debris from an alien spacecraft. Would that guess be a good one? There are obviously several problems with it. First, nobody on earth has ever produced an alien spacecraft for observation, so it's hard to test the idea. Second, unless alien spacecraft are invisible, there would be considerable evidence against the notion. Local radar, observations of other people, and satellite imagery could all demonstrate rather conclusively that no alien spacecraft were in the vicinity in the recent past. In short, there is a mountain of evidence against the guess.

Furthermore, there are clearly better guesses. Anyone noticing the broken down car could hazard a guess that makes more sense to the circumstances. In fact, a simple test will tell us whether this guess is accurate or not. If the man didn't actually need the part, and it didn't fit anywhere in his car, we would have to perhaps refine our guess. Perhaps it was from another car, which didn't suffer badly enough to stop running when the part was ejected. Perhaps it's from a riding lawnmower. (If there was a John Deere store in the vicinity, this guess would gain more credibility.)

Suppose now that after guessing that the part was from the broken down car, you tested your hypothesis by asking the man working on it, and it turned out that the part was not from that car. Has science failed us? Of course not! We have simply ruled out one possibility. The part might still be from a car. We could easily take it to an auto parts store and compare it with their inventory. If we found an identical part, we could be sure of it's identity. If, having tried several auto mechanics and auto stores, we were unable to find anyone with knowledge of cars who recognized the object, we would be forced to conclude that, barring any new information, the object was not from a car.

At this point, we could try various machine shops and manufacturing plants, repeating the same set of tests, until eventually, we correctly identified the object. This, again, is precisely what the scientific method prescribes. When we rule out one possibility, we keep looking for as long as it takes to find enough evidence to say what something is, or how it works. Here, we may ask a very pointed question. Supposing that we exhaust all of the known avenues for identifying the object, and we have still not determined its true nature. What is the correct answer to the question: “What is it?”

The answer, of course, is “I don't know.” This seems patently obvious, but it's astonishing how many times people forget this simple bit of logic. Suppose that, having exhausted our resources, we still had no evidence for what the object was. Would it be correct to say that since there was no evidence for its nature, that it must surely be part of an interstellar space station from the Andromeda Galaxy? Of course it wouldn't! In fact, it would be preposterously wrong to suggest such a thing, since the very result of our search demonstrated that there was no evidence for what the thing was!

It should be obvious at this point that whenever we don't have evidence for something, there's no way to form a reliable guess about its nature. However, just to drive the point home conclusively, let's do one more thought experiment. I have, on my desk at this moment, a picture of something. What is it?

Clearly, you have no idea. Perhaps, through random chance, you will guess the subject of the picture correctly, but it's highly unlikely. The only thing you know is that the subject can be rendered in picture form. You don't even know for certain that it exists on earth. Perhaps it is a photo of a far away galaxy, or of the upper atmosphere on Mars. (You don't even know if it's a photograph. Perhaps it's a drawing of something imaginary!) The point is that with no evidence, there is absolutely no way to make any kind of guess about what a thing is.

Suppose I ask you to now make a bet with me. If you guess correctly, you get ten thousand dollars, but if you guess wrong, you owe me ten thousand dollars, immediately. Unless you are a complete fool, you wouldn't dream of taking the bet, and for good reason. You have virtually no chance of winning. Now, suppose I gave you more information. Suppose I told you that it is a photograph of a baseball helmet. Would you be comfortable making the bet now? Probably not. If I added more information, and told you that it was a helmet from a Major League team, you would still only have a slim chance of guessing it – Far less than fifty-fifty, at any rate. However, if I told you that it was either a Chicago Cubs helmet or an Atlanta Braves helmet, you might feel sufficiently brave to take the bet.

Now, imagine that I told you that it's a photo of a Chicago Cubs helmet, and then asked you to make the bet with me. You'd be a fool not to take it, right? Or, would you? If you examined the evidence carefully, you'd realize that all you had to go on was my word. In fact, I would have a very strong motivation to tell you something inaccurate, so the weight of my testimony is almost nil. However, if I invited you over to my house and showed you the photo, allowing you to examine it to your heart's content, you would then have enough evidence to confidently take my bet.

This, again, is a step by step explanation for how (and why) science works. Some evidence is more reliable than others, and certainty can be measured in degrees. Imagine that I invite three people to make the same bet with me, and give each one a different set of evidence. To the first person, I say only that I have a picture of something. To the second, I say that I have a photo of a Major League baseball helmet. To the third, I provide the photograph itself. Each one of these three people, if forced to make a bet, has a certain likelihood of getting it right. The first person's chance is virtually zero. In fact, we could probably let him take thousands of guesses with confidence that he would not get it right. The second person, on the other hand, would certainly guess it within thirty tries, since that is the number of teams in Major League Baseball. The third person, unless he was monumentally stupid, would guess right on the first try. Though we cannot be 100% certain of his guess, it's fair to say that for all practical purposes, he will win ten thousand dollars in the next few seconds.

All of this, I hope, seems really straightforward and simple. Perhaps it is even insultingly so. However, it is apparently something that needs to be drilled into a lot of heads. The number of times I have had to defend the scientific method against other “sources of truth” is staggering. In fact, I have no doubt that there are many people who, upon reading this, will still cling to the idea that science isn't the only way to get knowledge.

Stay Tuned for Part II, in which I will spend more time on the notion of "alternatives" to science, the nature of religious claims, and the "Cult of Credulity."
