Here’s a puzzle. Most people in this country are religious. The god they believe in is an all-knowing, all-seeing, all-powerful god. If that is the case, why is it that people still do wrong things, things that they believe god will disapprove of? We know that even very religious people still lie and steal and cheat and do all manner of things that their religion tells them is wrong. But if they are sure that god knows all the things they do and is capable of punishing them, why do they still do it?

An obvious response is that human beings are not perfect, they are prone to temptation and that they are going to stray from the path of good behavior. A religious person might couch this in terms of human beings being weak and sinful and that they need to depend on god’s forgiveness to save them form their sinful natures. (An atheist would have to depend on his or her conscience and moral sense to help overcome the temptation to harm others for their own gain.)

That’s fair enough, but it seems to me that that only explains behavior in which people do something wrong on impulse or on the spur of the moment or by mistake because they did not have time to think things through or figure out what was the right or wrong thing to do. This can arise in tricky ethical situations where one has to make a decision on the spot and one can momentarily forget that god is watching your every move.

But that does not explain why religious people deliberately do things over a long period even when they know that what they are doing is wrong. Disgraced evangelist Ted Haggard, who railed against gays while having a relationship with a male prostitute, is only one highly publicized example of many cases of both clergy and laity indulging regularly and in a systematic manner in a whole host of activities that they strongly assert to be unquestioningly wrong, not just in sexual matters. If they really thought that god was watching their every move and knew their every motive and that their immortal souls were being imperiled, surely they would desist?

This leads me to wonder as to whether people really believe that god is all the he/she is cracked up to be. Perhaps what we have are closet atheists who pay lip service to the existence of a god but really don’t believe it, or at least have serious doubts. Thus they are gambling that they can get away with things they believe are wrong because they think there is a good chance that god does not exist.

It is true that people can be aware of being observed and yet forget that they are under surveillance and act as if they are unobserved. For example, most stores now have cameras that record everything that goes on but we usually ignore them. But our nonchalant behavior usually extends only to those actions that are not serious transgressions. So we might clown around, pick our noses, yawn without covering our mouths, scratch ourselves, and do similar things and not care that we were being watched and recorded. But a serious criminal acting with premeditation would be aware of the cameras and take steps to avoid being detected or identified while stealing. The greater the levels of security, the more likely people would avoid doing something wrong in that store.

Similarly, if you knew that your boss in your workplace had a surveillance system that was monitoring your every move and that people were watching you, surely that would affect your behavior and you would not do what you felt your boss did not want you to?

But we need not limit ourselves to petty criminality. The examples can be multiplied in the worlds of politics, big business, and in interpersonal relations. People consciously do wrong things (cheat on their taxes, defraud their companies, tell lies about others, etc.) all the time, gambling that they can escape the adverse consequences because the earthly authorities are not likely to find out because they do not have the resources to find out everything.

There is no reason to think that such people are any less religious than the average person. Since surely god is the most perfect security system of all, how is it that these people can so easily ignore the fact that the god they believe in knows exactly what they are up to and considers it wrong? Could it be that, deep down, people do not really believe in this kind of god at all, but are simply spouting the pieties that they have been brought up to say from the time they were children?

Are we really a world of closet atheists, too nervous to say out loud what they really believe? That would explain this cavalier attitude to god’s watchfulness but I suspect that religious people would not accept it.

I would be curious to hear alternative explanations for this.

POST SCRIPT: Photo touch ups

I recently saw a magazine cover photo of actress Sally Field. She is 60 years old but in that photo she looked a lot younger and I was impressed at how well she had taken care of herself. But was that photo touched up to ‘improve’ her looks? I don’t know but it is clear that the technology is there that gifted people can use to improve your image immensely.

Take for example, this photo. By moving the cursor over and off the image you can compare the images before and after the photo was touched up.

In another image, the bare shoulders from the image of a different woman was grafted onto the image of a woman who was wearing a dress. It is so well done as to be seamless and unnoticeable.

You can see more examples here. Just click on any thumbnail to get the full image.

These touch ups are done by the company Nasonart.com which is run by the editor of MachinesLikeUs, who is also a professional graphic designer, which explains why his website is so attractive!

In some ways, this is disturbing. Can you believe any image anymore? No wonder some women in this country suffer so much, trying to reach the unattainable standards of beauty they see in magazines. Granted, these women are attractive to begin with (he would have a tough time improving a photo of me!) but the retouching takes them to a level of flawlessness that is unattainable in real life.

But it seems that most young people now assume that the people they see in magazines have had their photos touched up, which is reassuring. I think high school yearbooks now do this kind of thing routinely, making people aware of the fact that things are not always what they seem.

It is interesting how one’s views can be changed by a comment. Such was the case with Cindy’s comment on my post regarding the absence of proof of an afterlife. Cindy said:

I tend to think that lack of belief in the afterlife is more fundamental to atheism than lack of belief in a God. I think I would have become an atheist a lot sooner if it weren’t for my emotional aversion to non-existence (which has really gone away after a years of thinking about it). Also, while a lot of people think it’s fun to talk about arguments for an against the existence of gods regardless of their beliefs, I’ve seen reasonable people reduced to tears with just a few good points raised about the lack of an afterlife. It seems like theism of any kind is based on two strong emotional ideas: 1) I’ll never really lose anything or anyone 2) The world is inevitably fair. And if they can’t have 2, they’ll still cling to 1.

I think Cindy is really on to something. Clearly people want to believe in the existence of a god and the after life, despite the lack of evidence for either. Although the two beliefs are linked, I used to think that wanting to believe in god was the primary impulse and that belief in an afterlife was something that came along with a belief in god, a fringe benefit if you like.

But Cindy’s suggestion is that the reverse is true, that what people really want to believe in is the afterlife, and that belief in god is merely a mechanism that enables that belief.

That makes a lot of sense. After all, god is an abstraction. Hardly anyone, except Pat Robertson, would claim that they have any kind of real relationship with god. Imagine meeting god. You really would not have much to say and it could be quite awkward, like encountering a stranger at a party. After a little small talk (“Hi, god, nice place you got here. So, . . . read any good books recently?”), you start wishing you could get away to the buffet table.

But that is not the case with people whom we like who have died. It would be like meeting a close friend after many years. We can’t wait to find out what they have been up to and getting them up to speed on out own lives. We can imagine ourselves talking to them for hours and days.

All of us have had people and pets whom we have loved and who have died. We have fond memories of them and the desire to continue that relationship is very strong. A recent study reported by Elizabeth Cooney in the Boston Globe of February 21, 2007 says that:

Contrary to traditional notions of grief after the death of a loved one, a new study finds that yearning is felt more powerfully than depression. . . . “Yearning is reacting to the loss of someone or something, and once that is gone, you miss it, you pine for it, you hunger for it, you crave it. That was the primary emotional experience after bereavement, rather than depression,” Holly G. Prigerson, one of the authors, said in an interview. . . . “People never get over a loss, they just get used to it,” Prigerson said. “Even years after someone dies, they get pangs of grief, they need to think about the person, and they miss them with heartache,” she said.

What people find most difficult to deal with in the death of a close loved one is missing the companionship that person provided. It is natural to want to believe in something, such as the afterlife, that promises that that link may someday be renewed.

In my own case, now that I think about it following Cindy’s comment, giving up believing in god was not that hard. But my father died nearly thirty years ago, before my own children were born. My greatest regret is that he would not see them growing up because I know how much he would have enjoyed knowing them and playing with them and how much they in turn would have enjoyed his company. The idea of meeting him again was much more appealing to me than the thought of seeing god. Believing that he was somewhere ‘up there’ looking down on my children was comforting. Even as I write these words, memories of him and the sadness associated with missing him comes flooding back. Giving up that belief was much harder than giving up belief in a god about whom I really knew nothing and with whom I had had no prior relationship or shared memories.

So it makes sense that belief in an afterlife is more important to people than belief in god and that maybe people desperately want to believe in god because it enables them to believe in an afterlife.

POST SCRIPT: Beautiful sand art

While the people who make sand art are obviously very skilled and patient people, what really amazes me is their willingness to spend so much time and effort something that gets destroyed soon after. You can see more exquisite sand art.

There were a couple of interesting (anonymous) comments in response to my post on what constitute rational and irrational beliefs. The writer said that I was overstepping the line that divided science from philosophy when I argued that religious beliefs were irrational. The arguments took a familiar form and went something like this:

1. We cannot prove that god does not exist.
2. Hence it is rational to believe that god exists.
3. Scientists should stick to the world of data and not venture to question god’s existence since that enters the realm of philosophy, not science. The author states that if a scientist is asked: ‘In your scientific opinion, does God exist?’ the proper answer should always be, ‘I don’t know. I don’t have any data on the subject.’

I will readily concede the first point, and in fact have done so previously (See here, here, and here.)

But the other two statements do not follow from the first. Just because we cannot prove, using data, the negation of some entity does not mean that it is reasonable to believe in that entity. Scientists constantly make judgments in the absence of data and act on those judgments. In fact, it is essential that they do so, as science could not proceed otherwise.

The only time that you can prove a negative is if you have the ability to do an exhaustive examination of every possible situation. As an example, I can prove to everyone’s satisfaction that no unicorns exist in my office because I can search every nook and cranny and show that none are there. But I cannot similarly prove that no unicorns exist anywhere on the Earth or elsewhere in the universe.

I also cannot prove the non-existence of magic unicorns in my office, that only materialize when I am not present and are capable of hiding all evidence of their visits before they disappear again. It seems to me that arguments for the existence of god are of this nature.

But there is another point about the word ‘proof’ that needs to be emphasized. When scientists use the word ‘proof’ they use it in a slightly differently way from the way mathematicians use it. In mathematics, a proof is a construct based on an agreed set of axioms and rules of logic. If someone challenges the validity of any of the axioms or one of the rules, then the proof is also called into question. But since the axioms are usually few in number and do not necessarily have to be based on data, mathematicians can agree on the validity of more things as working hypotheses than scientists can.

Scientific ‘proofs’ do not have the same level of rigor as a mathematical proofs because the axioms themselves are not simply assumptions but are also expected to justified based on evidence. Also there are far more explicit assumptions that go into scientific conclusions than go into mathematical proofs, thus opening them up to far more challenges. This greater degree of challenge that scientific assumptions receive makes scientific ‘proofs’ different from mathematical proofs. So although I and other scientists use the word proof frequently, we do understand that it is being used in a slightly different sense than a mathematical proof. The word proof is used to signify a reasoned judgment based on the merits of the evidence.

But just because scientific proofs do not have the same status as mathematical proofs does not mean that scientific conclusions cannot be extremely robust. Let me give an example. Most people readily accept that there are just two kinds of electric charge, positive and negative. This is about as well-established a ‘fact’ as one is likely to find in science. This is one of the most firmly held beliefs in all of science and the entire modern world is constructed on the basis of this two-charge model. No one even thinks of questioning this fact. (Note that ‘positive’ and ‘negative’ are just labels and the charges could just as well have been called things like ‘green’ and ‘blue’.)

The interesting question is how it is that we are so certain that there are just two kinds of charges that we base our entire society on it. Do we have certain proof that there are only two kinds of charges? Do we have direct data that no more charges exist? Have we looked everywhere and convinced ourselves of this? The answer to all three questions is no. So how is it that we are so sure that only two kinds of charges exist? It is because of the absence of certain kinds of data.

Here’s how that argument works. Suppose you have three charged objects A, B, and C. What scientists find is that if the charges are such that A and B attract each other and A and C attract each other, then it is always found that B and C repel each other. This set of three observations can be explained by (1) postulating that there exist just two kinds of charges, and (2) adopting a rule that says that like charges repel and unlike charges attract. No data has ever been seen that contradicts the consequences of these two assumptions.

Because of the absence of any data that contradicts any predictions based on those two statements , scientists will say that they are extremely confident that there are only two kinds of charges and this is all the ‘proof’ they need. But note that haven’t actually proved it in a mathematical sense. It is just a powerful inference based on the absence of certain kinds of data, but it is sufficient proof to convince scientists.

Notice though that even this ‘proof’ can be challenged. After all, we have done such experiments with just a few sets of charges. We have not exhaustively repeated them with every single charge that exists in the universe because it would be impossible to do so. As a result, someone can come along and say that scientists are wrong, that there does exist a third kind of charge but that either it has not been found yet or that it does not interfere with the experiments that scientists do. There is no way that scientists can prove this person wrong. How could they? But what they will do is ignore this argument as not worth responding to because that kind of argument has the same standing as magical unicorns in my office or a god who is determined to avoid leaving evidence of his/her existence.

A belief that has no observable consequences is of no use to scientists and they will work on the assumption that this third charge does not exist and that would be perfectly rational behavior. A person who clings to the belief in a mysterious third charge that has no observable consequences will be treated as somewhat eccentric.

Historians and philosophers of science have long pointed out that there is no proposition in science, however idiotic, that cannot be made immune from refutation by the addition of a protective belt of auxiliary hypotheses to shield its weaknesses. But if you want to convince scientists that something like a third kind of charge exists, you will have to provide positive evidence, some actual data that cannot be explained by a two-charge theory. For scientists, the absence of such evidence or data is taken as evidence of absence.

It seems to me that the arguments put forward by believers for the existence of god are of the same kind as those that might be put forward for a third charge: It exists but its effects cannot be observed. But just as scientists are perfectly justified in rejecting as irrational that kind of hypothesis when applied to a third charge and confidently proceeding on the basis that it is false, so it is that we can confidently reject the arguments currently given for the existence of god.

So although you may not be able to prove exhaustively that god does not exist, you cannot obtain a stronger scientific proof than what we currently have.

So if someone should ask me ‘In your scientific opinion, does God exist?’, I would answer ‘No’ with the same degree of confidence that I would say ‘No’ to the question as to whether a third type of electric charge exists.

POST SCRIPT: More lists of famous atheists

Some more lists of well-known atheists and agnostics, along with quotations from them justifying their inclusion in these lists, can be found here and here.

Although it should be obvious, I should add that the mere fact that someone famous is an atheist is not being offered as an argument in favor of atheism. Lists of this kind are simply to identify the members of an affinity group. One could do the same thing with lists of vegetarians or Bassett hound owners.

Some time ago, I wrote a post wondering if the Pope was an atheist. Of course, I do not know the Pope personally and he has never made a public statement to that effect. It would not really be a good career move on his part.

My point was that the more one thought seriously about god and studied religious texts, the more likely that it was that the whole idea of there being a god and heaven would be seen to be preposterous. All the logical fallacies and lack of evidence would become transparent. Hence I argued that it was amongst clergy and theologians that one was most likely to find atheists because those people are not stupid and they do study religion in depth. The higher one went in the hierarchy, the more intellectual were the clergy and theologians and so, given that logic, I argued that the Pope was a prime candidate for atheism.

Recently a friend of mine posed an interesting question. She said that none of us really know for sure if there is life after death or not, although all of us have our own beliefs. She wondered how differently we would live our lives if we could have conclusive proof either way. This led to an interesting discussion about what would constitute proof in such situations.
