Fine-tuning arguments for god

Religious people sometimes complain that scientists do not take their arguments for god seriously. I think that the opposite is true, and that scientists have gone out of their way to argue within the narrow framework set up by religious believers, when it is the whole premise that should be rejected.

Take, for example, the so-called anthropic principle/fine tuning argument that goes roughly as follows: We know that the conditions on Earth are conducive to the creation of life. Small changes in initial conditions of the universe would likely have made life impossible. Furthermore, the laws of physics and the associated fundamental constants seem to have just the right values to enable life to exist. Such ‘fine tuning’ is highly unlikely to have occurred by chance and thus points to the existence of a god who must have chosen those values in order to allow for life as we know it to come into being.

Some scientists have argued against god while staying within this framework, saying that fine-tuning does not imply the existence of god. After all, we don’t know whether other and different forms of life exist on undiscovered planets in this vast universe. Changing the laws and constants may simply mean that different forms of life have come into being that were suitable for those constants on other planets. Others have pointed out that the fine-tuning argument rests on what happens when you change only one parameter slightly while keeping all the rest fixed. Victor Stenger points to studies (God: The Failed Hypothesis, p. 148) that show that if you allow all the constants to change simultaneously, even by orders of magnitude, then you can still construct cosmologies in which stars, planets, and intelligent life can plausibly arise.

The willingness of scientists to do all this work shows how far they are willing to bend over backwards to accommodate religious arguments. So rather than scientists disrespecting religion, people like Stenger and Dawkins are actually granting it excessive respect by to treating these technical questions seriously when the big conceptual questions expose the silliness of the whole premise.

I have never understood the appeal of the anthropic/fine-tuning argument for god. Think for a moment what it requires us to believe. We are asked to believe that god first created humans (or at least had the idea of what humans should be like), an organism that needed very special conditions (such as oxygen and water) in order to exist. God then had to solve the problem of how to create a planet that had the ingredients to support the existence of the preplanned humans, and then had to fine tune everything else in this vast universe to enable that planet to come into being a long time after he triggered the big bang. We are being asked to believe, in effect, that the entire universe was reverse-engineered by god to meet the needs of humans as currently exist.

Reverse engineering is what we mere mortals have to do because we have no choice. We have to take the universe and life on Earth as given, and the best we can do is try and figure out how they got to be that way. But why would god have to do this? If he was the original designer, present right at the beginning, surely it would have been easier for him to design humans who were robust enough to be able to survive in all kinds of environments. Why would he needlessly box himself in, as the anthropic/fine-tuning seems to imply?

As Stenger astutely points out (p. 154) “In fact, the whole argument from fine-tuning ultimately makes no sense. As my friend Martin Wagner notes, all physical parameters are irrelevant to an omnipotent God. “He could have created us to live in hard vacuum if he wanted to.” “

POST SCRIPT: George Bush, comedy writer

Some time ago, President Bush famously asked: “Is our children learning?” Well, he now has the answer.

Does god and religion satisfy other human needs?

In the previous post I listed four possible reasons why religion should not be undermined:

  1. God does exist and there is empirical support in the form of evidence.
  2. God does not exist but believing in god satisfies deep human psychological and emotional needs and that getting rid of those beliefs would lead to people feeling emotionally bereft of support.
  3. Religion and belief in god supplies a foundation for morality and without it we would have lawlessness, anarchy, and general social breakdown.
  4. Religion is a useful tool for the ruling elites that enables them to maintain social order, by convincing oppressed people to accept injustice and inequality as part of a divine plan and defer their wishes for relief until the next life, where they are told they will reap great rewards.

Should religion be undermined?

Religion is such a ubiquitous phenomenon, so pervasive in all aspects of people’s lives, that imagining life without it is very difficult. It is like asking an American teenager to imagine life without their cell phone. Not only are people extremely resistant to giving up the idea of god, they also resist giving up qualities they ascribe to god even if those qualities cause severe logical difficulties.

Pinning down the properties of god

One of the difficult points on which discussions between atheists and religious believers flounder is that while there is a fair degree of uniformity amongst atheists as to what they do and don’t believe, there is a huge diversity among religious believers about what they believe. This can be disconcerting because in the middle of a discussion, a religious person will often say, “Oh, but I don’t believe in that stuff. My idea of god is quite different.” Understandings of god tend to be so fluid that it enables believers to slide from one to another whenever one particular formulation comes under close scrutiny and is shown to be untenable. People tend not to want to be pinned down on what they actually mean by god. This is more so in the case of more sophisticated believers. Fundamentalists are more concrete in their beliefs.

When I was debating the intelligent design movement in Kansas, I would find that the views ranged from believing in the literal truth of the Bible in every detail to people who regarded the Bible as metaphors but still believed in a personal god who could intervene in the actions of the world. If one goes outside the world of intelligent design advocates, one finds an even broader spectrum, people who are what I call ‘almost atheist believers,’ who call themselves ‘spiritual’ and whose idea of god is so vague that no empirical statement can be made about it at all. For some, god is somehow synonymous with nature, for others it is the creator of the big bang and nothing else, and so on. They are the people whom Daniel Dennett describes as people who believe in belief, who need to feel that there is something transcendent in their lives and will construct it to meet their needs.

So in order to have a useful dialogue, it may clarify things and avoid misunderstandings if each person knew where the other stood. It is useful, for example, to see if someone accepts the idea that god has the qualities of being omnipotent (all-powerful), omniscient (all knowing), and omnibenevolent (all good).

We know that belief in this god immediately runs into the problem of theodicy, the problem of defending god’s goodness and omnipotence when bad things occur, such as the death of an infant or widespread tragedy in the recent tsunami. Epicurus (341-271 BCE) posed the essential and, to my mind, the ultimate contradiction that believers in such a god face:

Is god willing to prevent evil but not able? Then he is not omnipotent.
Is he able but not willing? Then he is malevolent.
Is god both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him god?

This obvious logical contradiction has resulted in some theologians arguing against assigning all three qualities to god. But which one(s) should be jettisoned? Most people who are not theologians are reluctant to abandon any because it would seem to devalue their concept of god as someone to whom all positive superlatives should apply. Anything less than absolute perfection is seen as unworthy. Such people then have to resort to the ‘mysterious ways clause’ (MWC) which argues that that while god does have all those three qualities (and more), the reason that things appear to be contradictions to us is because our minds cannot understand god’s plans or that he has not confided his plans to us in a manner that we can understand.

But the odd thing is that although believers, by invoking the MWC, have effectively argued that logic and reason and evidence (things they routinely value and use in other areas of their lives) cannot be used to argue against the existence of god, they still try to use evidence and reason to argue in favor of god, and resort to the MWC only when that attempt fails and they end up in a dead end from which there is no escape.

In an attempt to clarify what people mean by god, Victor J. Stenger in his book God: The Failed Hypothesis: How Science Shows That God Does Not Exist (2007, p. 12) defines what he sees as the properties of the Judeo-Christian-Islamic god as gleaned from their religious texts and official doctrine.

[The Judeo-Christian-Islamic] God is not the god of deism who created the world and then left it alone, or the god of pantheism, who is equated with all existence. The Judeo-Christian-Islamic God is a nanosecond-by-nanosecond participant in each event that takes place in very cubic nanometer of the universe, from the interactions of quarks inside atomic nuclei to the evolution of stars in the most distant galaxies. What is more, God listens to every thought and participates in each action of his very special creation, a minute bit of organized matter called humanity that moves around on the surface of a tiny pebble in a vast universe.

Stenger spells out the basic elements that go into this model of god (p. 41):

  1. God is the creator and preserver of the universe.
  2. God is the architect of the structure of the universe and the author of the laws of nature.
  3. God steps in whenever he wishes to change the course of events, which may include violating his own laws as, for example, in response to human entreaties.
  4. God is the creator and preserver of life and humanity, where human beings are special in relation to other forms.
  5. God has endowed humans with immaterial, eternal souls that exist independent of their bodies and carry the essence of a person’s character and selfhood.
  6. God is the source of morality and other human values such as freedom, justice, and democracy.
  7. God has revealed truths in scriptures and by communicating directly to select individuals throughout history.
  8. God does not deliberately hide from any human being who is open to finding evidence for his presence.

This seems like an accurate list to me, corresponding to my own understanding of what mainstream believers say. Stenger deliberately does not include the problematic trinity of omnipotent, omnibenevolent, and omniscient qualities (especially the ability to know the future) since those lead to immediate and severe logical contradictions in explaining away things like the tsunami, and makes religion too easy a target to attack. He also does not consider the views of scriptural literalists, the so-called fundamentalist Christians and Jews and Muslims, who take their creation stories and history and images of god straight from their holy books and argue (say) for a 6,000 year old Earth. Such people have abandoned science entirely and there is little one can say to them.

Stenger’s book is a detailed analysis of the more sophisticated arguments put forward for a god and he argues that none of them stand up to scrutiny. He looks at all the things that we can infer from the properties of the above god and examines the commonly stated arguments and evidence in favor, some of which have been discussed here too: the appearance of design in nature and the universe; the sense that we have a mind and soul apart from the body; claims of immortality and the afterlife; the idea that the origin of the universe needs an initiator; the ‘fine-tuning’ or anthropic principle argument; the answering of prayers; and the morals and values argument. He finds that none of the evidence produced in favor of these stands up in the face of close scrutiny. The conclusion is simple: In the absence of evidence in support of it, the god hypothesis is rejected. As Stenger says (p. 71): “Earth and life look just as they can be expected to look if there is no designer God.”

Stenger is careful to point out that this does not rule out all gods. The MWC enables you to define god any way you like and assign it any properties you wish and be immune from contradiction. But atheists see this exercise as a waste of time.

The problem that arises in discussions with believers is that defenders of god tend to shift around among these qualities so that when (say) feature #2 is shown to cause problems with logic and evidence, they shift to #3, and then when that is shown to be also fraught with problems, they move on to #6. And, when all else fails, there is always the fallback option of invoking the MWC (which is the same as abandoning #8) and serves as the ultimate get-out-of-jail-free card.

Perhaps the discussions with religious people would be would be more fruitful if right at the beginning they listed which of the above properties of god they agree with. That would make for a far more focused discussion.

How to disrupt dinner parties

Last weekend I went to a dinner party where there were people from Sri Lanka whom I had not met before. When Sri Lankans meet for the first time, there is a fairly standard ritual that occurs. People try to find connections between you and them, starting with others who share your name (e.g., “Are you related to the Singham who used to work at X/who married Y/who lives in Z?”) and then on to questions about where in Sri Lanka your family is from and what K-12 school you went to. The last question is important because Sri Lankans are quite attached to their schools and many cities with a large expatriate populations even form associations based on these old school ties and hold dances, sporting events, and other elaborate get-togethers.

During a casual conversation at the dinner with three of my fellow guests (all sisters), they asked me the usual questions and then one of them went off-script and asked me which church I went to. I replied that I did not attend any church since I was an atheist.

The sharp intake of breath and astonished looks in response alerted me that this had gone over big. It was as if I had walked into a vegan conference eating a hamburger. It turned out that not only were the three of them Christians, but they were of the extremely religious “born again” variety. The stunned look on their faces at my revelation got even worse when they realized that I had once been a Christian. They simply could not understand how anyone who had once been a Christian could not believe any more, and for the next hour they proceeded to try and convince me that I had made a grave mistake. Of course, their arguments consisted entirely of quotations from the Bible, all of which I have heard many times before. It simply did not seem to register with them that there was no point in using the Bible as evidence to someone who did not believe that it was god’s revealed word.

Another interesting point was that they felt that my atheism had to be because I had not “accepted Jesus as my personal lord and savior”, which is the standard by which evangelical Christians judge whether you are a “true” Christian or not. In fact, they kept insisting that I had never been a “true” Christian because of my failure to pledge such allegiance. In my religious days in high school and college, I had attended many religious services where the preacher, at the end of a stirring sermon asserting that we were all sinners and in the grip of Satan, would ask people to come up front and pledge their lives to Christ so that they could be cleansed of their sin. I never obeyed this “altar call”, although many of the people I knew had done so in the past and they often asked me to join them. During one of those services, I was startled when the friend who had invited me suddenly clutched my sleeve and with tears in his eyes told me that Jesus was calling me and implored me to obey the call, helpfully adding that someone else who had rejected the call just a few weeks earlier had subsequently been run over by a bus right after the service. It was an awkward moment but I said no. I always rejected such altar calls, since I felt even then that a god who depended on a formulaic repetition of a slogan as a sign of faithfulness (and apparently was willing to kill someone who would not comply) was hardly worth following.

After some time, my companions at the dinner asked if we could pray together so that Jesus could enter my soul. Although I am an obliging sort and the discussion had been friendly, I had to draw the line and say no. It seemed like another altar call and, to my mind, highly presumptuous. While they were free to pray for whomever and whatever they wanted to on their own time (and they said they would pray for me later anyway), I wanted no part of it. It struck me then that if I told them about my dream from last week they would probably have thought that that really was a sign from god trying to save me from my path to doom.

I think that what puzzled my dinner companions the most was the fact that I was perfectly happy being an atheist and was not looking for anything more in the spiritual realm. They kept repeatedly asking me whether I felt a “yearning for something more”, whether I was “missing something in my life” and whether I had a “gap in my soul”. (My responses? No. No. No. To the last one I added that I did not have a soul and that did nothing to improve my image in their eyes.) They seemed to assume that since belief in the Christian god was such an essential part of their lives, that it must be the same for other people. They simply could not conceive that it was possible for someone to have a fulfilling life without god. And not just any old god, but their own particular Christian Jesus-god package.

One would have to say that my dinner companions exhibited all the signs of religious fanaticism. Not that they would in any way do harm to others such as fly planes into buildings. On the contrary, I am quite certain that they are very good people who would not dream of harming anyone. But they are religious fanatics in that they are absolutely sure that their particular version of religion is the right one, their own religious text is infallible, they have a personal relationship with god, that followers of all other religions are wrong, that those who do not believe what they do are lost souls who will suffer eternal damnation, and that it is their duty to try and convert others to their belief.

But while these particular people may be harmless, it is a very thin line that separates “good” fanatics from the bad. The problem is that if you accept that that kind of unquestioning faith and allegiance as a good thing, it becomes hard to condemn the actions of those who, again on the basis of that kind of faith and following what they believe are the dictates of their god, commit the most atrocious crimes. Voltaire’s remark keeps coming to my mind: “As long as people believe in absurdities, they will continue to commit atrocities.”

It was an interesting evening.

Mother Theresa’s mixed legacy

Mother Theresa’s legacy was not an unmixed one. On the one hand, she did important work that others were not doing, and took in the sick and dying from the streets of Calcutta and provided them with beds to spend their last days with at least some minimal care and cleanliness. On the other, she exhibited a serious tone-deafness when it came to hobnobbing with rich and powerful people, who, by giving her cause money, tried to immunize themselves from criticisms for their own barbaric cruelty to the people of their country.

Michael Hand in his review of Christopher Hitchens’ book The Missionary Position: Mother Teresa in Theory and Practice (Verso, 1995) gives some examples.

Mother Theresa and signs from god

In the previous post, I wrote about Mother Theresa’s unfulfilled yearning to get a sign from god that he existed and that her faith was justified. What is most surprising to me is that she did not receive such a sign.

Most people who desperately want to believe in god, like Mother Theresa clearly did, are quick to seize on random events and coincidences that we all experience in our lives and interpret them as signs from god. If you really need a sign from god, it is not hard to manufacture one to your satisfaction. Surely there must have been many such instances in her life that would have served her purposes, such as receiving a generous donation for her mission at a time when they desperately needed money or having one of her charges unexpectedly recover from near death?

Mother Theresa’s dilemma

There have been a flurry of news items and commentary about the publication of a book of Mother Theresa’s letters, which reveal that she struggled for most of her life with the fear that there was no god. Excerpts from the letters (as quoted in the press) show that during almost her entire ministry, she struggled with deep doubt, saying things like: “Where is my faith?. . .Even deep down… there is nothing but emptiness and darkness. . . . If there be God — please forgive me. . . Such deep longing for God. . . . Repulsed, empty, no faith, no love, no zeal. . . What do I labor for? . . . If there be no God, there can be no soul. If there be no soul then, Jesus, You also are not true.”

The letters reveal a woman who yearned for some sign that her belief in god was justified, for some sense that there was a godly presence, and that she failed to receive such reassurance, although she publicly maintained a face of unwavering devotion.

Religious apologists have been quick to try and shield her from suggestions that she was a hypocrite acting in bad faith, hiding her disbelief in god behind a façade of piety. They point out (correctly) that most religious people have doubts from time to time and struggle to maintain their beliefs. It is perhaps only the psychotic who are absolutely certain that god exists and think that god speaks to them in clear and unambiguous ways. So while her doubts seem to have been deeper and longer lasting than most religious people would admit to, they are by no means unique.

It is not hard to see why Mother Theresa’s belief in god was being constantly challenged. Most ordinary religious people are fortunate in that they do not often have to deal with tragedy and sadness in their own lives, excepting for maybe one or two major events, thus making it easier to maintain belief in a benevolent deity. But she was dealing on a daily basis with the sickness and death of huge numbers of men and women, young and old, who had not done anything that merited the deep misfortunes that befell them. Under those circumstances it would have been inhuman for her not to question the benevolence of god. It was perfectly natural for her to seek some sign from god that all the suffering she saw had some purpose and meaning, and to despair when she did not receive such an assurance.

In some ways, Mother Theresa may have been a victim of her own success, trapping her into a belief structure that she could not reject without also undermining the work she was trying to do. Most of us who can switch from believers to atheists and the only disruption this may cause is within our small circle of family and friends. But she was an enormously successful figure for the image of the Catholic Church, generating immense amounts of goodwill and money because of her work with the desperately poor people of Calcutta. She would have known that to make her doubts public, let alone come out as an atheist, would have resulted in a huge blow to the faith of others. Such an admission would have been to turn her back on the basis on which she had started her entire life’s work. While she could have continued her work as a doubter, that would have risked losing the official backing of the Catholic Church and its publicity apparatus, which was undoubtedly helpful in efforts to raise money.

In the normal course of events, when we fail to find evidence for something, it is considered to be a reasonable thing to not believe in that thing. This is why we do not believe in the existence of unicorns or fairies and do not hesitate to publicly say so. To do otherwise would be considered hypocrisy. But in the case of Mother Theresa, the split between her public unwavering piety and her private doubts is being portrayed, oddly, as something virtuous. I find it hard to see how it can be virtuous to publicly profess devout belief while harboring serious doubts. That simply imposes feelings of guilt on those who also do not have certainty, making them feel that their own faith must be somehow inadequate or inferior to hers. Surely it would have been better for her and others if she had said publicly that she had her doubts, just like everyone else, but that she hoped that her belief and hope in god would be vindicated in the afterlife.

As Daniel Dennett points out, this hiding of doubt behind the mask of certainty cannot be a good thing:

[T]here is good reason to believe that the varieties of self-admonition and self-blinding that people have to indulge in to gird their creedal loins may actually cost them something substantial in the moral agency department: a debilitating willingness to profess solemnly in the utter absence of conviction, a well-entrenched habit of deflecting their attention from evidence that is crying out for consideration, and plenty of experience biting their tongues and saying nothing when others around them make assumptions that they know in their hearts to be false.

It is hard not to sympathize with Mother Theresa’s lifelong struggle to find some reason to believe. It must have caused her considerable anguish to fear that she may have been living a lie. I believe that such struggles are far more common than we realize and are due entirely to expecting people to believe in things for which there is no evidence and making them feel guilty when they cannot do so with easy assurance. This is the kind of thing that happens when we elevate ‘faith’, i.e., belief in the absence of evidence, to a virtue.

The problem with religion-4: Corrupting the minds of children

(For previous posts in this series, see here.)

I started this series with Matt Ridley’s quote: “The Asian tsunami was not an act of god but 9/11 was” and will end with it, because it says something very profound.

Religious apologists for Islam are quick to claim that the 9/11 perpetrators were not following their “true” religion, that god would not have condoned this act. But what is the basis for this claim of exemption? After all, the perpetrators themselves seemed to think that they were indeed the ones that were following the true religion. In his periodic video surfacings, bin Laden appears quite confident that he is serving god well, as is Bush when he speaks of his motivations.

The problem with religion-3: All prayer, all the time

(For previous posts in this series, see here.)

In the comment that triggered this series of posts, the rise of liberation theology in South America was used to argue as a case where religion played a positive role. But let us see the liberation theology movement in its full context.

For the better part of the twentieth century, many of the countries of Central and South America were run by murderous despots, while Catholicism was the dominant religion in those countries. Around 1960, ‘liberation theology’ came into being, led by some intellectuals and clergy, arguing for a radical interpretation of the Gospels, focusing on those elements of the Bible that seemed to call for an end to oppression. But while there was this grass root effort to change the relationship of religion to state power, what was the church doing in those days, apart from a few brave priests and nuns? How many Catholic eminences took stands similar to even the limited calls for justice that Archbishop Romero took, or even came out in support of him while he was alive? Why did the Vatican and the Catholic Church not call for massive protests and agitation to overthrow the government of El Salvador when Romero was gunned down, in his own cathedral no less, by government death squads? If liberation theology was considered a good Christian thing, why was it not officially adopted by the Vatican?
