The God Delusion, Chapter 10 – A much needed gap?


Is a belief in God beneficial? Do we need God in our lives? Richard Dawkins discusses this issue in chapter 10 of the God Delusion. The first point he makes is that, whether or not a belief in God is beneficial in terms of psychological health or whatever, says nothing about the existence of God. There are studies indicating that religious people, on average are happier and healthier than atheists. The difference was not big but it was significant. However, it would be very erroneous to conclude that just because religion is correlated with happiness, God must exist… Dawkins writes:

"Religion's power to console doesn't make it true. Even if we make a huge concession; even if it were conclusively demonstrated that belief in God's existence is completely essential to human psychological and emotional well-being; even if all atheists were despairing neurotics driven to suicide by relentless cosmic angst - none of this would contribute the tiniest jot or tittle of evidence that religious belief is true. It might be evidence in favour of the desirability of convincing yourself that God exists, even if he doesn't."

Personally I do think that the world would be a better place if people would have an evidence based world view. Politicians today often get stuck when religious arguments are brought to the table. Should Jerusalem be in the possession of the Israeli, or the Palestinian's? How do you argue with Bush when he claims that the Iraq invasion was a mission given to him by God? There is just not so much you can say in response to such an argument. To be fair, this was not his primary argument for going to war, but my point stands nevertheless.

I do not believe in God, yet I consider myself happy and I enjoy my life. When I face misfortunes I do not pray to God to help me, rather I try to come up with a concrete and effective solution to whatever it is I am facing. I realize of course that I have been born in a wealthy part of the world and that my miseries are nothing compared to the miseries that the average human being must face, yet even for them I think that it would be better not to rely on God to console and fix things. An additional bonus that you get as an atheist, at least to the extent that atheists do not believe in reincarnation, is that you value your time here on earth more. I do not believe that I will be reborn when I die, therefore I want to make the best of the time that I have here on this planet. For this reason I am also unlikely to end up as a suicide bomber. Only a very religious person would sacrifice something as valuable as his or her own life in order to kill other innocent people.

In short, there are plenty of reasons to be grateful for our time here on earth. One does not need God to have some substance in life. My life is filled with substance, and I think that for most people, even for religious people, the principal sources of happiness lie outside of the realm of religion. I end with these words from the God Delusion which illustrates my point well.



"But could it be that God clutters up a gap that we'd be better off filling with something else? Science, perhaps? Art? Human friendship? Humanism? Love of this life in the real world, giving no credence to other lives beyond the grave? A love of nature, or what the great entomologist E. O. Wilson has called Biophilia"

The God Delusion, Part 9 – Childhood, abuse, and escape from religion



Chapter nine in The God Delusion, as the name suggests, deals with the way in which children are indoctrinated into faiths. In my opinion chapter nine is the most controversial one in the entire book. Personally I agree with most of what Dawkins writes, though occasionally I can have some understanding for a certain degree of child indoctrination. It is after all difficult to act in a completely neutral way towards children without letting your ideology shine through at all. I expect that it is even more difficult if you believe passionately in something as many religious people do. Personally when a child asks me about my beliefs I always say that I do not believe in any God, but I am also quick to point out that there are people who thinks otherwise. I will gladly explain why I do not believe in a God, but I try to not force the child into adapting my views. I also try to ask children what they think, thus encouraging them to think for themselves. These are my ideals, but I admit that sometimes I don't live up to them entirely, and I cannot expect religious people to do so if I do not… Dawkins writes (and I think he may be going a bit too far here).

"In short, children have a right not to have their minds addled by nonsense, and we as a society have a duty to protect them from it. So we should no more allow parents to teach their children to believe, for example, in the literal truth of the Bible or that the planets rule their lives, than we should allow parents to knock their children's teeth out or lock them in a dungeon."

Nevertheless, the damage that results form child labeling and child indoctrination is undeniable. Suicide bombers often commit their deeds because it will bring financial support to their family, however, I do not think they would have done what they do was it not for their strong religious faith. As Dawkins often points out, it is also very weird that we label children as Muslim or Christian considering how complicated belief systems really are. Have they read the bible and reflected on its validity? I seriously doubt it… It is entirely equivalent to labeling children according to some political affiliation, e.g. "a communist child", or a "social democrat child". Children should be taught how to think, not what to think. Dawkins writes:





"I thank my own parents for taking the view that children should be taught not so much what to think as how to think. If, having been fairly and properly exposed to all the scientific evidence, they grow up and decide that the Bible is literally true or that the movements of the planets rule their lives, that is their privilege. The important point is that it is their privilege to decide what they shall think, and not their parents' privilege to impose it by force majeure."

In Sweden there is an ongoing debate (S) about whether confessional private schools should be allowed or not. Today we have a compromise in which religious movements are allowed to run schools as long as they do not have any religious perspectives in the normal subjects. They are however allowed to have some isolated religious events such as morning-prayer. As a liberal I find it hard to have a strong opinion in this debate. The essential question for me is how much the religious events in these schools contribute to indoctrination of children as well as whether going to such a school will prevent the children from meeting people with different ideologies. For instance, the Plymouth Brothers (S), a sect that has been allowed to start a private school in Sweden, have an ideology that explicitly says that it is not allowed to eat in the company of a "devil worshipper" like myself. Dawkins writes (and this I agree with completely):

"Let children learn about different faiths, let them notice their incompatibility, and let them draw their own conclusions about the consequences of that incompatibility. As for whether any are 'valid', let them make up their own minds when they are old enough to do so."

Another theme in chapter nine is the obsession that some people have with preservation of religious diversity which they see as positive seemingly independent of the consequences. The argument goes something like this. Who are we to judge that say female circumcision is wrong - that is their culture and we should respect that. In one American TV-program the ritual sacrifice of a young Inca girl was hailed as being exotic and a wonderful example of cultural diversity (the event took place about 500 years ago). Dawkins writes:

"Humphrey's point - and mine - is that, regardless of whether she was a willing victim or not, there is strong reason to suppose that she would not have been willing if she had been in full possession of the facts. For example, suppose she had known that the sun is really a ball of hydrogen, hotter than a million degrees Kelvin, converting itself into helium by nuclear fusion, and that it originally formed from a disc of gas out of which the rest of the solar system, including Earth, also condensed . . . Presumably, then, she would not have worshipped it as a god, and this would have altered her perspective on being sacrificed to propitiate it."…

"Humphrey makes the point that no adult woman who has somehow missed out on circumcision as a child volunteers for the operation later in life."

To sum everything up, though I think it is categorically wrong to impose your view on children I can understand that in practice this may be difficult to attain to a perfect degree. Beliefs will inevitably shine through. However, I cheer everyone who encourages autonomous thought in children. Ask them what do you think?, do you believe in God?, how do you think the world came to be?, and other questions like that? Let them have their say and let them know that they can believe what they want. At the very least, don't be like pastor Roberts who is running a Hell House in which children are taught what will happen to them if they would be so evil as to have an abortion (they have very generous age limits compared to for instance Hollywood, see picture). Pastor Roberts says:

"I would rather for them to understand that Hell is a place that they absolutely do not want to go. I would rather reach them with that message at twelve than to not reach them with that message and have them live a life of sin and to never find the Lord Jesus Christ. And if they end up having nightmares, as a result of experiencing this, I think there's a higher good that would ultimately be achieved and accomplished in their life than simply having nightmares."

What would be your choice of death?


When I was little I often contemplated and discussed with my friends what would be the best way to end your days? I actually still think about this sometimes. I have often thought to myself that a high fall would be pretty neat, but then again, maybe you don't enjoy that kind of fall the same way you enjoy a rollercoaster… Floating into space is another alternative which have seemed like an attractive one to me. Until today all my reflections had been built on nothing, however, now that I have discovered this article from New Scientist, I am able to make a more informed choice about my preferred death scenario.

According to the article written by Anna Gosline, death is almost invariable caused by a lack of oxygen in the brain. How this oxygen deprivation arises is different from case to case. In the article ten different means of dying are discussed: drowning, heart attack, bleeding to death, fire, decapitation, electrocution, fall from a height, hanging, lethal injection, and explosive decompression. If your main priority is to not experience pain then your choice should be decapitation (a good decapitator is a requirement though), or fall from height. If conducted properly, these two methods will result in a rapid death and hence a minimum amount of suffering. Things can go wrong though. When Mary Queen of Scots was decapitated (see picture), the axeman failed to completely separate the head from the rest of the body in his first three attempts. He eventually finished the job with a dagger… Decapitation is probably the fastest way of dying, however, even an isolated head contains enough oxygen to function for about ten seconds. Hence, just like chickens can run around headless following decapitation, humans can operate their facial muscles. I don't know whether they can also experience consciousness, but I cannot see any reason why not (I wonder what it would feel like to just be a head)…



The "float into space scenario" has become a lot less attractive after reading the article. It seems to be a lot like drowning where you panic because you cannot get any oxygen. Additionally, your body will swell up like in the movie Total Recall (though they probably exaggerated a bit), not very pleasant in other words. Likewise, electrocution and lethal injection, seems to be rather unattractive choices. Electrocution is supposed to knock out the brain swiftly, however, whether this really happens is a matter of debate (the cranium is a good insulator and may thus prevent the bulk of electricity from entering the brain). An active brain will experience horrible pains as a result of the burns and the high current flowing through the body.

In the light of this, lethal injection seem like a much better alternative, at least if the dosing is right. Before getting the actual killer substance convicts are given a large dose of anesthesia and after that they won't feel a thing. The problem is just that occasionally the given dose is too small and then this alternative is no longer very attractive. Finally, falling from height does seem to be a fairly good alternative. At terminal velocity (the velocity you reach before the wind resistance balances the gravitational force), which is about 200km/h, the blow that you experience upon landing is so great that you can be fairly certain of a swift fatal dysfunction in your body, either the heart or the lungs explode or you crack your spine. If you try landing on your head results will be even "better"…

What would you choose?

Ps: I am not suicidal, I find life too facinating to want to kill myself, so you don't need to call any agencies...

Complementary and alternative medicine - Spontaneous recovery from disease


Alternative and complementary medicine refers to products and practices which are not part of the standard medical procedure that you get when you go to a hospital. Though the terms are often used interchangeably, alternative refers to when a practice aspires to replace standard medical care whereas complementary practices only aspire to complement standard medical procedure. For sure, for sure, medical research is far from a complete understanding of the physiology and anatomy of humans, and there are almost certainly many effective remedies which are not a part of the standard repertoire today. In the future we will no doubt see many advances in science and in consequence, new therapies to treat disease.

Having said this, complementary and alternative medicine suffers from what I consider to be a much more serious problem. First of, many of the techniques and practices used in alternative and complementary medicine have never been tested, or have not gained any support, in controlled studies and hence they have never proved to have any "real effect" (as opposed to placebo effect which they probably do have). Even more serious, because alternative therapies have often not been tested properly, it is hard to tell whether they have any serious side effects. What is almost certain is that if a particular substance has any effect at all, then it is more than likely to have side effects as well (see table at bottom of this article).

Sometimes alternative practices turn out to be effective and when they do they are eventually assimilated into standard medical practices. To be fair, this assimilation process can sometimes be agonizingly slow and some doctors are probably too conservative, however, the essence of the matter is that when an alternative treatment or therapy has gained enough support in studies it will cease to be "alternative" and become "standard". This is to some extent true for acupuncture, which is now used occasionally as a treatment for various conditions even though it has long been controversial. However, importantly, the mechanism that makes acupuncture work seems to be different from what has been claimed by those who have used this procedure in the past. No meridians have ever been demonstrated. Instead it seems that acupuncture stimulate pain sensing nerve endings. These nerve endings in turn exercise a form of lateral inhibition meaning that they block other pain sensing nerve endings around them, thus preventing the patient from experiencing pain in that area.

Complementary and alternative practices can often give the illusion of being effective because we recover spontaneously from diseases. We have an impressive immune system, which deals with seemingly limitless pathogens in an extremely efficient and competent manner. I am making up the numbers here, but say that after taking a certain herb 90% of all people recover from the flue within a week. Wow, surely there must be something to it then? But wait a minute. Almost everyone (say 90%) recovers from the flue within a week if they just stay home in bed. Suddenly these herbs do not seem that fantastic, and they seem even less attractive if you take into account the often excessive price tags.

Back pain is another example that deserves mention, and these figures I am not making up (they come from a lecture I attended recently). Nine out of ten (90% that is) cases of acute back pain will go away after one week. Combine this with the fact that 60-80% of all individuals will experience back pain sometime in their lifetime and what you get is an awful lot of cases of back pain that goes away in one week. Not surprisingly, at least not to a cynic like me, there are a huge number of alternative or complementary therapies for back pain, and they all seem really successful as long as you do not compare them to no treatment at all…



Here is my advice, my alternative therapy if you like. If you experience back pain, and don't have any other serious symptoms such as your vertebrae penetrating your back muscles (in which case I would advice going to a doctor), don't spend your money on all sorts of alternative/complementary therapies, rather relax for one week and see if the pain simple goes away (in most cases it will). Once you have recovered, use the money you would have spent on a therapy on something nice, such taking your girlfriend to a cozy restaurant. If the pain does not go away after one week, go see a doctor and have your back checked up…

Writing about alternative medicines is something that really warms my heart. I have written about homeopathy here, here and here, and here I have written about the role of the placebo effect.

Blog marketing tips – Building traffic and getting stats


I am now 62 posts into my life as a blogger. Some weeks have been more productive than others but overall I am happy with my publishing frequency. If you have a blog which you want people to read then it is not always enough to write superb posts. In order to get people to view your blog you need to market yourself, otherwise people will not find your blog. So far I have not found any method that gives me loads of visitors without me having to do anything, however, some ways work better than others. Here are my tips.

The most basic tip of all is to keep writing. If you do not update your blog frequently, people will not visit your blog frequently. It is also very important to establish some contacts. Go to other blogs and comment on their posts. If you appreciate a particular blog you can add a link to it on your blog and then ask them if they want to do the same. Commenting a lot on other blogs also spreads your name and in consequence makes people interested in what you have to say.

The next step is to get your blog indexed by search engines and blog catalogues. The easiest way to do this is to use a pinging service. Personally I use Pingoat and Ping-o-matic. Both of these pinging services announce your new posts to a few dozen search engines and blog catalogues.


If you have accomplished the basics above (not a trivial feat), then you can start to look at different web-applications that will help you build traffic. If you have a blog in English, some time to spend, and want to build traffic, then my best tip is to sign up for Blogexplosion. The concept is simple, if you read other peoples' blogs then they will read your blog. At blogexplosion you get 0.5 visitors for every 30s visit you make on a blog. Every now and then you also get so called "mystery credits", which is just a kind of bonus. So you really get a little bit more than 0.5 visitors on your blog for every 30s visit to another blog. There are various similar services, including Blogmad and Blogadvance, but Blogexplosion has worked best for me so far.




It is nice to be able to see how traffic builds on your new blog, and there are some neat ways of visualizing the trends. For basic stats and trends (see picture above) I use Blogflux topsites, which generates charts showing how many visitors I have had for the last month. Blogflux mapstats (see picture below) is another excellent service which allows you to see the location of the people who have visited your blog as well as the site from which they came, or alternatively, what they put into their search engine to find you. ClustrMaps (see picture far above) is a similar service which has the extra positive aspect of accumulating statistics – it does not throw away all the stats every day. However, ClustrMaps does not give you as much details as Blogflux mapstats, so it is up to you to decide.



There are of course countless additional tips, however, so far these have served me the best.

The God Delusion, part 8 – What’s wrong with religion? Why be so hostile


I do not think that religion is the only source of evil in this world. Humans have an instinct to form groups, and to amplify the differences between the in-group and the out-group. I am myself a fan of Manchester United, and for some weird reason I can get a little bit upset when someone criticize a player in the team or something similarly harmless. Now, I would never act on such feeling, however, there are fans or hooligans who in fact get into fights for such reasons, unbelievable as that may sound… I think that mankind will probably always find something to fight about, however, I also think that religion is the worst culprit of all when it comes to creating conflicts between groups. In chapter eight of The God Delusion, Richard Dawkins addresses the very frequent question "what is wrong with religion"?

The danger of Islamic fundamentalism is obvious to most people. Last weekend I watched the movie United 93. Even though I have seen those planes fly into the world trade center thousands of times I still just cannot understand or accept that any human being can plan and execute such a deed which intentionally strikes against civilians, many of whom have had absolutely nothing to do with the miseries that the Muslim world has experienced. To take a plane full of civilians in great despair and then fly that plane right into a building with more such civilians is an act that must require a lot of faith. 9/11 was no zenith of terrorism. According to “The Religion of Peace.com” Islamic terrorists have carried out more than 9500 deadly terror attacks since 9/11.

Islam is not the only religion with blood on its hands though. In Africa, countless massacres has been carried out in the name of Christianity. See for example Joseph Kony (see picture), proclaimed spirit medium and leader of the Lord’s Resistance Army.


So where does religious extremism stem from, what causes it? I have not read any studies on this, and if someone could enlighten me then I would be grateful. However, I think it is beyond reasonable doubt that religion has to take part of the blame. In particular, the problem with almost all religions is that they teach the young that blind faith is a virtue. To doubt in God when there is no evidence is for some reason a horrible crime. As a consequence, religious people often cannot tell you what it would take for them to stop believing. This is one of the things that separates science and religion. Dawkins writes:

But my belief in evolution is not fundamentalism, and it is not faith, because I know what it would take to change my mind, and I would gladly do so if the necessary evidence were forthcoming.

There are well documented differences in peoples' tendency to be open minded. Some individuals are born with a taste for absolute rules and principles and a great dislike for grey-scale ethics and knowledge. One could add to the speculation above that if individuals of this kind, who score low on openness, is brought up in say a Christian family, then it is probable that this individual will become more extreme in his/her faith than the parents. Maybe, unlike the parents, the youngster decides that the bible must be read literally and then he read from the bible that “He that sacrificeth unto any god, save unto the LORD only, he shall be utterly destroyed” (Exodus 22.20), right there you have the birth of an extremist. Dawkins explains it perhaps more elegantly than me when he writes:

The teachings of 'moderate' religion, though not extremist in themselves are an open invitation to extremism.

The religious movement in the United States seems to have abandoned the founding fathers' ideal of a true secular state. The intelligent design movement tries to bring religion into the classroom, a goal which may become a problem for them since the creator is not specified. Meanwhile there are the so called pro-life politicians (ironically, the same politicians tends to be strong proponents of the death penalty), who want a ban on abortion for faith based reasons. The religious movement in America has culminated (I hope) in a group referred to by outsiders as The American Taliban. I can find no difference between their rhetoric and that of Osama Bin Laden. According to Ann Coulter:

"We should invade their countries, kill their leaders and convert them to Christianity. We weren't punctilious about locating and punishing only Hitler and his top officers. We carpet-bombed German cities; we killed civilians. That's war. And this is war."



Anyways, the main problem with faith and the answer to the question "what is wrong with religion" is that it idealizes faith without evidence. It is really hard to argue with someone who merely says "this is what I believe, and nothing can change that". Such an attitude makes it impossible to have discussion that is of any use. I will end with the following quote from Bertrand Russell (see picture) (which can also be found in The God Delusion):

Many people would sooner die than think. In fact they do.

Relativism

It is of course true that we cannot know anything for certain. For all we know, we may be living in "The Matrix", and everything we see is mere computer simulations. Likewise, we can never know for sure that a theory is true in an objective sense. I consider these two statements as uncontroversial, however, when relativists go one step further and argue that all theories are equivalent since no theory can be proven, that is when I must disagree…


People who use this reasoning have completely forgotten about the concept of evidence and prediction. Though a theory can never be proven in the absolute sense it can be better or worse at describing reality. Just as simple example there are people who claim that the world is spherical (or almost spherical), and there are those who claim that it is flat (based on religious reasoning I might add). What predictions does each of these two theories make? Well, one very simple prediction is that a round earth should cast "round" or banana shaped shadows on the moon when the earth is between the sun and the moon. If the earth was flat on the other hand, the shadow should be flat as well. Everyone who has ever gone out to watch the moon knows that the round earth theory gives the more accurate prediction. We cannot know for certain that the earth is round, but the predictions it makes agree with what we see. When a prediction is correct we can call that evidence. My point is simply that people do not walk around and think that the earth being flat and the earth being round are two equivalent theories just because neither can be proven. Almost everyone believes that the earth is round because there is so much evidence in favor of that theory.


I have previously argued that in fact it does not really matter whether a theory is true in the objective sense. As long as a particular theory is very good at predicting the world as we see it, it is a good theory and we should simply act as if it was true. It is this mentality together with the scientific method, which reduces the risk of seeing evidence where there is none that has brought us to where we are today. Here it is important to remember that if a theory is true in the objective sense, then all predictions derived from that theory would have to be true as well.


Relativists also like to point fingers at the scientific method. One frequent argument that you hear from relativists is that throughout history there has been paradigm shifts in almost all sciences. In astronomy for example we have gone from the Copernican system, to the Newtonian, to Einstein's relativity. Furthermore they claim that these paradigm shifts occur, not because latter theories are more accurate, but due to cultural factors. Relativists who use this argument, first of all, forget that history is also a science. They are using evidence which has been produced using the scientific method – the very same method which they are criticizing. Clearly hypocritical...


Besides, it is clear to me that all shifts in astronomy have been progressive. The details of the various paradigm shifts may have been influenced by sociological factors, however, the main reason for all the shifts have been that they make better predictions. Newton's theory of gravitation gives a better description than Copernicus theory, and Einstein's theory of relativity make better predictions than Newton's theory. Old theories are exchanged with new ones when the new ones are better at describing the world as we perceive it.


This will be all I write about relativism for now, but check back later if you want to read more. For some reason I end up in discussions about relativism very often, and therefore I also have many thoughts on the subject. Many of the arguments that I present here have been influenced by this book (see picture above), which I recommend to everyone.
