The Language of God-5: The nasty problem of miracles

(This series of posts reviews in detail Francis Collins’s book The Language of God: A Scientist Presents Evidence for Belief, originally published in 2006. The page numbers cited are from the large print edition published in 2007.)

As I said before, sophisticated religious believers like Francis Collins and John Lennox always start out by arguing for a God of the Ultimate Gaps. The insurmountable problem that they then face is that their emotional need to believe in a Personal God who communicates with them individually and can answer their prayers requires them to go well beyond the narrow role they initially assigned to a God of the Ultimate Gaps, and results in them getting tied up in all kinds of logical knots.

Because they have to find ways for god to act in the universe, they inevitably make additional assumptions to allow for that. Collins does this by expanding the powers of god, so that miracles violating natural laws are now possible, even though this contradicts his earlier claim that god is not in our universe and thus we should not expect to find tangible evidence of his presence in the universe.

The end of god-12: God and natural disasters

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

In the previous post, we saw how religious believer try to absolve god for his failure to stop wars and genocide by arguing that god gives us free will and that it is therefore our fault when things like that happens. This is a weak argument at best but it does not address another problem of theodicy: how to explain away the massive suffering caused by natural disasters and disease, where no human agency is involved.

Just this week we have immense death and destruction due to the cyclone in Myanmar and the earthquake in China. A few years ago we had the Asian tsunami. And we have had hundreds of millions of deaths over the centuries due to diseases like the plague, malaria, and typhoid. We have horrible diseases even now, afflicting all kinds of people down to the youngest children.

Why does an all-powerful and loving god allow such cruel things to happen? No convincing answer has ever been given for this, though some radical clerics like Pat Robertson and Jerry Falwell are quick to say that these calamities are deliberate punishments by god for people’s sins. Of course they mean the sins of people they disapprove of (like gays) and not their own.

But such weird attitudes do not come just from well-known crackpots like Robertson. Even high dignitaries of so-called mainstream liberal churches like the Church of England are not immune from this kind of childish thinking. Take for example the remarks of some Church of England bishops after floods devastated large parts of England a little over a year ago.

The floods that have devastated swathes of the country are God’s judgment on the immorality and greed of modern society, according to senior Church of England bishops.

One diocesan bishop has even claimed that laws that have undermined marriage, including the introduction of pro-gay legislation, have provoked God to act by sending the storms that have left thousands of people homeless.
. . .
The bishop [of Carlisle], who is a leading evangelical, said that people should heed the stories of the Bible, which described the downfall of the Roman empire as a result of its immorality.

“We are in serious moral trouble because every type of lifestyle is now regarded as legitimate,” he said.

“In the Bible, institutional power is referred to as ‘the beast’, which sets itself up to control people and their morals. Our government has been playing the role of God in saying that people are free to act as they want,” he said, adding that the introduction of recent pro-gay laws highlighted its determination to undermine marriage.

“The sexual orientation regulations [which give greater rights to gays] are part of a general scene of permissiveness. We are in a situation where we are liable for God’s judgment, which is intended to call us to repentance.”

In some sense, radical clerics like Robertson and Falwell and the bishop of Carlisle are only following to their logical conclusion where a belief in an all-powerful god leads them. If god is omnipotent, then he can prevent any natural disaster and if he does not do so, he must have a reason. The only reason they can think of is that this must be an act of retributive justice. Of course, earthquake, tsunamis, and floods that kill vast numbers of people indiscriminately do not look like the acts of a loving god, but these people tend to favor ‘tough love’ doctrines, as long as that tough love is applied to other people and not to them. Jerry Falwell died suddenly while in his office last year but I did not hear his good buddy Robertson suggesting that god had killed him because he thought Falwell was a major sinner in addition to being an annoying pest.

While one can think of many possible social and economic reasons why god might get mad, for some reason radical clerics tend to get really worked up by the thought of sexual (particularly homosexual) activities, and this is usually the reason they bring forward to explain any natural disaster.

Those people for whom the god-is-love idea is more important than the god-is-just idea have a harder time explaining natural catastrophes. They tend to have to resort to saying that god must be having some plan that we mere mortals cannot comprehend. When confronted with the problem of explaining massive numbers of deaths of even infants, believers shrug their shoulders and say the equivalent of “Well, stuff happens, and we don’t know why. We have to just assume god has a good reason for letting it happen even though he could prevent it.”

Some resort to saying that god created the universe and its laws and has simply decided to allow events to unfold according to those laws whatever the consequences (i.e., they invoke the God of the Ultimate Gaps when it is convenient to do so), and that the reasons for his leave-alone policy are inscrutable. This is the infamous ‘mysterious ways clause’, the get-out-jail-free card that religious people play when they are faced with something they cannot explain away.

They do not seem to realize that such a statement of ignorance of god’s intent is in direct contrast to their assured statements at other times: that they know that god is loving and just, cares for each one of us, wants us to be good and join him in heaven, and that it pains him when we stray from the path of righteousness. How could they know all that about the mind of god and yet not know why he allows droughts and floods and earthquakes?

In other words, popular religious apologists try to sidestep the theodicy problem by shifting between the contradictory beliefs of saying they know and understand the mind of god and god’s intentions and nature, while at the same time saying that the reasons for his actions are utterly inscrutable.

One cannot avoid the conclusion that these are the justifications of people who desperately want to believe. Some people have a deep emotional need to believe that there is a mysterious, invisible, father figure looking out for just them, and they will make up any story that allows them to cling to that, however irrational it may be.

Although the model of god-as-loving-father may look superficially more sophisticated than the god-as-authoritarian-puppeteer believed by the woman in Kansas, they both ultimately spring from the same source. First you decide what you want or need to believe, and then you make up some story that allows you to believe just that.

The only way that such people will abandon their beliefs is if they realize for themselves that their beliefs are divorced from reality and that a reality-based belief structure can be far more satisfying.

The end of god-11: Trying to find reasons to believe in god

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

In response to the powerful new evidence and arguments against the existence of god brought forward by the new atheists, the defenders of religion have had to regroup and respond. The next series of posts will look at some of these developments on the pro-religion side.

Today I will look at the popular arguments in favor of god, those advanced by regular people who are not professional theologians or academics. These people are simply trying to figure out for themselves why it is reasonable to still believe in god while living in a world that seems to be functioning as if there is no god at all.

Such people must yearn to return to the days when god would routinely demonstrate his existence and power by burning bushes without them being reduced to ashes, turning water into wine, stopping the sun in its tracks, raising people from the dead, and so on. Alas, those days seem to be permanently gone. The only miracles that seem to occur these days are the occasional reports of a crying statue or an image of Jesus on a piece of burnt toast, hardly the kinds of things to fire the imagination of the devotee. God even passed up the chance to provide evidence for his existence by winning a NASCAR race.

At one extreme of the popular arguments are the religious fundamentalists. Their approach is illustrated by what happened to me after I debated the intelligent design creationism (IDC) advocates in Kansas in 2002. A very earnest woman came to talk to me after the session. She was clearly disturbed by my challenge to the IDC members on the panel to provide the kind of predictions that scientists expect of any theory, and my conclusion that since they had failed to do so, IDC did not belong in science. She wanted very badly to have god as part of science, so she had carefully written out on a piece of paper what she felt was a definition of science that would not contradict the existence of god. Her definition said that everything that had ever occurred and would occur in the future was directly due to god and so everything in the world was due to god’s actions and thus science could never refute god’s existence.

She had made god’s actions synonymous with everything that happens. And she was absolutely right that science cannot provide evidence against such a definition of god. How could it?

But more sophisticated people shy away from such an extreme, and one might even say childish, view of god as it seems to deny the existence of any form of human agency. According to that model of god, we are all just puppets following a rigid script written long ago by an authoritarian puppeteer. The idea of good and evil and free will are casualties of such a model and it is not very flattering to the human self-image as thinking persons.

In order to preserve the concept of morality and that we are agents who can choose how we act, other religious believers replace the model of god-as-authoritarian-puppeteer with that of a god who has given us free will to choose how we act. People also like to think of their god as a loving god who is also all-powerful.

The catch is that with this new model, you immediately run up against the problem of theodicy: why a loving and all-powerful god allows awful things to happen.

When I was growing up as a Christian and struggling with this particularly difficult question, the answer that was offered and that satisfied me at that time (and coincidentally was repeated just this week in a private communication from a reader of this blog) was that while god wants us to do good, he has given us free will and allows us to exercise it to choose whether we do good or evil and some people pick the latter. The lesson we learn from our bad decisions is that we must do better in future.

This model of god is that of a parent who can if he wishes dictate to his child what to do but does not do so because that would be stifling to the child’s growth to adulthood. Instead god lets people learn for themselves from their own actions and mistakes, even if the short-term consequences are appalling. In such a model, the evil acts caused by humans (like the genocides of Native Americans, Jews, Cambodians, Rwandans, etc.) are not the will of god but due to people making bad choices.

In other words, gods don’t kill people, people kill people.

The model of god-as-loving-parent is not without its own serious problems. It assumes that while god has the power to stop this kind of slaughter at any time, he allows massive acts of evil to occur because he views them as learning experiences. Is this argument really credible to anyone except those who want to believe at any cost? If a parent let his child slaughter the neighborhood children in a playground with a machine gun, we would hardly accept his explanation that he was allowing his child to exercise his free will so that he could grow and learn from his mistakes that guns are dangerous and that it is wrong to kill, and thus become a better person in the future.

An interesting feature of this model of god is how such religious apologists are quite confident that they know what god’s intentions are, and they seem sure that he is loving, cares for each one of us personally, that he wants us to use our free will wisely and in good ways, and that it pains him when we stray and do bad things. This is quite an extraordinary level of knowledge of the mind of an omnipotent deity. Of course, they have no evidence for any of these assertions. All the awful events named above can be explained as well (or even better) by saying that god is a vindictive and cruel entity who enjoys pitting one group against another, and seeing the suffering that ensues.

POST SCRIPT: Einstein’s views on religion

Given his well-deserved reputation as a deep thinker and thoughtful and humane person, Einstein’s views on religion have always been a source of great interest and his varying statements have been interpreted as being both supportive and dismissive of a belief in god.

In a little known letter written in 1954, he seems quite unequivocal in his contempt for religion:

In the letter, he states: “The word god is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can (for me) change this.”

Einstein, who was Jewish and who declined an offer to be the state of Israel’s second president, also rejected the idea that the Jews are God’s favoured people.

“For me the Jewish religion like all others is an incarnation of the most childish superstitions. And the Jewish people to whom I gladly belong and with whose mentality I have a deep affinity have no different quality for me than all other people. As far as my experience goes, they are no better than other human groups, although they are protected from the worst cancers by a lack of power. Otherwise I cannot see anything ‘chosen’ about them.”

The history of western atheism-3: The first published atheist

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

In his BBC4 TV series A Rough History of Atheism Jonathan Miller awards the honor of being the first published atheist to France’s Paul Henri Thiery, Baron D’Holbach (1723-1789). As the Encyclopedia Brittanica entry on him says:

His most popular book, Système de la nature (1770) (“The System of Nature”), published under the name of J.B. Mirabaud, caustically derided religion and espoused an atheistic, deterministic Materialism: causality became simply relationships of motion, man became a machine devoid of free will, and religion was excoriated as harmful and untrue. In Le Christianisme dévoilé (1761; “Christianity Unveiled”), published under the name of a deceased friend, N.A. Boulanger, he attacked Christianity as contrary to reason and nature.

It is said that the Baron’s salon was a congenial meeting place for all manner of freethinkers, including Benjamin Franklin during his stay in France, but some of his guests were so alarmed at the inflammatory nature of the speculations that occurred that they stopped coming. Even a nobleman like D’Holbach had to be cautious about his views, as atheism was grounds for persecution and even execution, so his works on these subjects were published pseudonymously.

Buddhism and atheism

Of all the major religions, Buddhism (as originally formulated) probably comes closest to atheism and being scientific. If someone, for whatever reason, cannot believe in god but feels uncomfortable with calling themselves an atheist and feels the need to be part of some well-established religious tradition, Buddhism probably meets that need best.

In is book The World’s Religions (p. 82-153) Huston Smith outlines the basic elements of Buddhist philosophy, as articulated by its founder Siddhartha Gautama, who was born in the region now known as Nepal around 563 BCE and lived for about eighty years. It is important to realize that the name Buddha is technically not that of a specific person but given to anyone who achieves enlightenment, and Siddhartha Gautama did not even claim to be the first one to do so. But over time ‘the Buddha’ has become known as the name of this particular Buddha, similar to the way ‘Jesus the Christ’ has now become simply Jesus Christ, the name of Jesus.

The devil in the details

In one of the classic Peanuts cartoons, Linus says that when he grows up he wants to become a great doctor and rid the world of illness. His sister Lucy tells him he can’t because he doesn’t care enough about humanity. An indignant Linus responds, “I love humanity! It’s people I can’t stand!”

I remembered that cartoon as I was writing the recent series of posts about the difficulties with believing that the mind/soul is a non-material entity that can exist independently of the material body and brain. I wrote about how Descartes struggled with how to understand the actual working of the model.

What the neuroscience community thinks about the mind/brain relationship

The idea that the mind is purely a product of the material in the brain has profound consequences for religious beliefs, which depend on the idea of the mind as an independent controlling force. The very concept of ‘faith’ implies an act of free will. So the person who believes in a god is pretty much forced to reject the idea that the mind is purely a creation of the brain. As the article Religion on the Brain (subscription required) in the May 26, 2006 issue of the Chronicle of Higher Education (Volume 52, Issue 38, Page A14) says:

Pope John Paul II struck a similar theme in a 1996 address focusing on science, in which he said theories of evolution that “consider the mind as emerging from the forces of living matter, or as a mere epiphenomenon of this matter, are incompatible with the truth about man. Nor are they able to ground the dignity of the person.”

As I wrote yesterday, the flagging intelligent design creationism (IDC) movement seems to be hoping for some fresh energy to emerge from the work of psychiatric researcher Dr. Schwartz. Or at the very least they may be hoping that they can persuade the public that the mind does exist independently of the brain. But they are going to have a hard time getting traction for this idea within the neurobiology community. There seems to be a greater degree of unanimity among them about the material basis of the mind than there is among biologists about the sufficiency of natural selection.

Stephen F. Heinemann, president of the Society for Neuroscience and a professor in the molecular-neurobiology lab at the Salk Institute for Biological Studies, in La Jolla, Calif., echoed many scientists’ reactions when he said in an e-mail message, “I think the concept of the mind outside the brain is absurd.”

But the ability of the neurobiology community to do their work unfettered by religious scrutiny may be coming to an end as increasing numbers of people become aware of the consequences of accepting the idea that the mind is purely a product of the brain. People might reject this idea (and be attracted to the work of Dr. Schwartz), not because they have examined and rejected the scientific evidence in support of it, but because it threatens their religious views. As I discussed in an earlier posting, people who want to preserve a belief system will accept almost any evidence, however slender or dubious, if it seems to provide them with an option of retaining it. As the article says:

Though Dr. Schwartz’s theory has not won over many scientists, some neurobiologists worry that this kind of argument might resonate with the general public, for whom the concept of a soul, free will, and God seems to require something beyond the physical brain. “The truly radical and still maturing view in the neuroscience community that the mind is entirely the product of the brain presents the ultimate challenge to nearly all religions,” wrote Kenneth S. Kosik, a professor of neuroscience research at the University of California at Santa Barbara, in a letter to the journal Nature in January.
. . .
Dr. Kosik argues that the topic of the mind has the potential to cause much more conflict between scientists and the general public than does the issue of evolution. Many people of faith can easily accept the tenets of Darwinian evolution, but it is much harder for them to swallow the assumption of a mind that arises solely from the brain, he says. That issue he calls a “potential eruption.”

When researchers study the nature of consciousness, they find nothing that persuades them that the mind is anything but a product of the brain.

The reigning paradigm among researchers reduces every mental experience to the level of cross talk between neurons in our brains. From the perspective of mainstream science, the electrical and chemical communication among nerve cells gives rise to every thought, whether we are savoring a cup of coffee or contemplating the ineffable.
. . .
Mr. [Christof] Koch [a professor of cognitive and behavioral biology at the California Institute of Technology] collaborated for nearly two decades with the late Francis Crick, the co-discoverer of DNA’s structure, to produce a framework for understanding consciousness. The key, he says, is to look for the neural correlates of consciousness – the specific patterns of brain activity that correspond to particular conscious perceptions. Like Crick, Mr. Koch follows a strictly materialist paradigm that nerve interactions are responsible for mental states. In other words, he says, “no matter, never mind.”

Crick summed up the materialist theory in The Astonishing Hypothesis: The Scientific Search for the Soul (Scribner, 1994). He described that hypothesis as the idea that “your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules.”

What many people may find ‘astonishing’ about Crick’s hypothesis is that among neurobiologists it is anything but astonishing. It is simply taken for granted as the way things are. Is it surprising that religious believers find such a conclusion unsettling?

POST SCRIPT: Why invading Iraq was morally and legally wrong

Jacob G. Hornberger, founder and president of The Future of Freedom Foundation has written a powerful essay that lays out very clearly the case of why the US invasion and occupation of Iraq is morally and legally indefensible, and why it has inevitably led to the atrocities that we are seeing there now, where reports are increasingly emerging of civilians being killed by US forces. Hornberger writes “I do know one thing: killing Iraqi children and other such “collateral damage” has long been acceptable and even “worth it” to U.S. officials as part of their long-time foreign policy toward Iraq.”

The article is well worth reading.

Religion’s last stand-2: The role of Descartes

In the previous posting, I discussed two competing models of the mind/brain relationship.

It seems to me that the first model, where the physical brain is all there is and the mind is simply the creation of the brain, is the most persuasive one since it is the simplest and accepting it involves no further complications. In this model, our bodies are purely material things, with the brain’s workings enabling us to think, speak, reason, act, and so forth. The idea of ‘free will’ is an illusion due to the brain being an enormously complicated system whose processes and end results cannot be predicted. (A good analogy would be classically chaotic systems like the weather. Because of the specific non-linearity of the equations governing weather, we cannot predict long-term weather even though the system is a deterministic and materialistic.)

The second model, that of an independently existing non-material mind/soul, separate from the brain and directing the brain, immediately raises all kinds of problems, which have long been recognized. The scientist-philosopher Rene Descartes (1596-1650) of “I think, therefore I am” fame was perhaps the first person to formulate this mind-body dualism (or at least he is the person most closely associated with the idea) and it is clear that he felt that it was necessary to adopt this second model if one was to retain a belief in god.

But he realized immediately that it raises the problem of how the non-material mind/soul can interact with the material brain/body to get it to do things. Princess Elizabeth of Bohemia, with whom Descartes had an extended correspondence, was unable to understand Descartes’ explanation of this interaction and kept prodding him on this very question. Descartes had no adequate answer for her, even though both clearly wanted to believe in the existence of god and the soul. In the introduction to his translation of Descartes’ Meditations and other Metaphysical Writings (which contains extended segments of the Elizabeth-Descartes correspondence), Desmond Clarke writes:

After repeated attempts to answer the question, how is it possible for something which is not physical to interact with something else which, by definition is not physical?, Descartes concedes that he cannot explain how it is possible.

But he tried, using the best scientific knowledge available to him at that time. He argued that the location of the soul’s interaction with the body occurred in the pineal gland.

As is well known, Descartes chose the pineal gland because it appeared to him to be the only organ in the brain that was not bilaterally duplicated and because he believed, erroneously, that it was uniquely human. . . By localizing the soul’s contact with body in the pineal gland, Descartes had raised the question of the relationship of mind to the brain and nervous system. Yet at the same time, by drawing a radical ontological distinction between body as extended and mind as pure thought, Descartes, in search of certitude, had paradoxically created intellectual chaos.

Although Descartes failed in his efforts to convincingly demonstrate the independent existence of the soul, research into the relationship of religious beliefs to the central nervous system of the brain has continued.

Descartes is an interesting character. Much of his scientific work, and even his temperament, seem to indicate a materialistic outlook. But at the same time, he took great pains to try and find proofs of god’s existence. One gets the sense that he was a person trying to convince himself of something he did not quite believe in, and had he lived in a different time might have rejected god with some relief. The article on Descartes in Encyclopaedia Britannica Online, 13 June 2006 says:

Even during Descartes’s lifetime there were questions about whether he was a Catholic apologist, primarily concerned with supporting Christian doctrine, or an atheist, concerned only with protecting himself with pious sentiments while establishing a deterministic, mechanistic, and materialistic physics.

The article points to reasons for the ambiguousness of his views, which could be due to the fact that there was, at that time, considerable fear of the power of the Catholic Church and this may have guided the way he presented his work.

In 1633, just as he was about to publish The World (1664), Descartes learned that the Italian astronomer Galileo Galilei (1564–1642) had been condemned in Rome for publishing the view that the Earth revolves around the Sun. Because this Copernican position is central to his cosmology and physics, Descartes suppressed The World, hoping that eventually the church would retract its condemnation. Although Descartes feared the church, he also hoped that his physics would one day replace that of Aristotle in church doctrine and be taught in Catholic schools.

Descartes definitely comes across as somewhat less than pious, and non-traditional in his religious beliefs.

Descartes himself said that good sense is destroyed when one thinks too much of God. He once told a German protégée, Anna Maria van Schurman (1607–78), who was known as a painter and a poet, that she was wasting her intellect studying Hebrew and theology. He also was perfectly aware of – though he tried to conceal – the atheistic potential of his materialist physics and physiology. Descartes seemed indifferent to the emotional depths of religion. Whereas Pascal trembled when he looked into the infinite universe and perceived the puniness and misery of man, Descartes exulted in the power of human reason to understand the cosmos and to promote happiness, and he rejected the view that human beings are essentially miserable and sinful. He held that it is impertinent to pray to God to change things. Instead, when we cannot change the world, we must change ourselves.

Clearly he was not orthodox in his thinking. Although he tried to believe in god, it was his emphasis on applying the materialistic principles that he used in his scientific work to try and identify the mechanism by which the mind interacts with the brain that has the potential to create the big problem for religion.

To sum up Descartes’ argument, following sound scientific (methodological naturalistic) principles, he felt that if the mind interacted with the brain, then there had to be (1) some mechanism by which the non-material mind could influence the material brain, and (2) some place where this interaction took place. Although he could not satisfactorily answer the first question, he at least postulated a location for the interaction, the pineal gland. We know now that that is wrong, but the questions he raised are still valid and interesting ones that go to the heart of religion.

POST SCRIPT: Documentary on Rajini Rajasingham-Thiranagama

I have written before about the murder of my friend Rajini Rajasingham-Thiranagama, who had been an active and outspoken campaigner for human rights in Sri Lanka. I have learned that a documentary about her life called No More Tears Sister is the opening program in the 2006 PBS series P.O.V.

In the Cleveland area, the program is being shown on Friday, June 30, 2006 at 10:00pm on WVIZ 25. Airing dates vary by location, with some PBS stations showing it as early as June 27. The link above gives program listings for other cities. The synopsis on the website says:

If love is the first inspiration of a social revolutionary, as has sometimes been said, no one better exemplified that idea than Dr. Rajani Thiranagama. Love for her people and her newly independent nation, and empathy for the oppressed of Sri Lanka – including women and the poor – led her to risk her middle-class life to join the struggle for equality and justice for all. Love led her to marry across ethnic and class lines. In the face of a brutal government crackdown on her Tamil people, love led her to help the guerrilla Tamil Tigers, the only force seemingly able to defend the people. When she realized the Tigers were more a murderous gang than a revolutionary force, love led her to break with them, publicly and dangerously. Love then led her from a fulfilling professional life in exile back to her hometown of Jaffna and to civil war, during which her human-rights advocacy made her a target for everyone with a gun. She was killed on September 21, 1989 at the age of 35.

As beautifully portrayed in Canadian filmmaker Helene Klodawsky’s “No More Tears Sister,” kicking off the 19th season of public television’s P.O.V. series, Rajani Thiranagama’s life is emblematic of generations of postcolonial leftist revolutionaries whose hopes for a future that combined national sovereignty with progressive ideas of equality and justice have been dashed by civil war – often between religious and ethnic groups, and often between repressive governments and criminal rebel gangs. Speaking out for the first time in the 15 years since Rajani Thiranagama’s assassination, those who knew her best talk about the person she was and the sequence of events that led to her murder. Especially moving are the memories of Rajani’s older sister, Nirmala Rajasingam, with whom she shared a happy childhood, a political awakening and a lifelong dedication to fighting injustice; and her husband, Dayapala Thiranagama, who was everything a middle-class Tamil family might reject – a Sinhalese radical student from an impoverished rural background. Also included are the recollections of Rajani’s younger sisters, Vasuki and Sumathy; her parents; her daughters, Narmada and Sharika; and fellow human-rights activists who came out of hiding to tell her story. The film rounds out its portrayal with rare archival footage, personal photographs and re-enactments in which Rajani is portrayed by daughter Sharika Thiranagama. The film is narrated by Michael Ondaatje, esteemed author of The English Patient and Anil’s Ghost.

I knew Rajini well. We were active members of the Student Christian Movement in Sri Lanka when we were both undergraduates at the University of Colombo. It does not surprise me in the least that she threw herself with passion into the struggle for justice. She was brave and spoke the truth, even when it was unpalatable to those in power and with guns, and backed up her words with actions, thus putting her life on the line for her beliefs. Such people are rare. I am proud to have known her.

Religion’s last stand: The brain

As almost everyone is aware, the science-religion wars have focused largely on the opposition of some Christian groups to the teaching of evolution. The religious objections to Darwin’s theory of natural selection have been based on the fact that if the universe and the diversity of life that we see around us could have come about without the guidance of a conscious intelligence like god (even operating under the pseudonym of ‘intelligent designer’), then what need would we have for believing in a god?

But while evolution has been the main focus of attention, I see that as more of a preliminary skirmish to the real final battle battleground for religion, which involves the brain.

The crucial question for the sustaining of religious beliefs is the relationship of the mind to the brain. Is the mind purely a creature of the brain, and our thoughts and decisions merely the result of the neurons firing in our neuronal networks? If so, the mind is essentially a material thing. We may have ideas and thoughts and a sense of consciousness and free will that seem to be nonmaterial, but that is an illusion. All these things are purely the products of interactions of matter in our brains. In this model, the mind is entirely the product of the physical brain. This premise underlies the articles selected for the website MachinesLikeUs.com.

Or is the mind a separate (and non-material) entity, that exists independently of the brain and is indeed superior to it, since it is the agent that can cause the neurons in our brain to fire in certain ways and thus enable the brain to think and feel and make decisions? In this model, the ‘mind’ is who ‘I’ really am, and the material body ‘I’ possess is merely the vehicle through which ‘I’ am manifested. In this model, the mind is synonymous with the soul.

If we are to preserve the need for god, then it seems that one must adopt the second model, that human beings (at the very least among animals) are not merely machines operating according to physical laws. We need to possess minds that enable us to think and make decisions and tell our bodies how to act. Most importantly, our minds are supposed to have the capacity of free-will. After all, what would be the value of an act of ‘faith’ if the mind were purely driven by mechanical forces in the brain?

It should be immediately obvious why the nature of the mind is a far more disturbing question for religion than evolution is or ever will be. With evolution, the question centers around whether the mechanism of natural selection (and its corollary principles) is sufficient to explain the diversity of life and changes over time. As such, the debate boils down to the question of weighing the evidence for and against and determining whether which is more plausible.

But plausibility lies in the eye of the beholder and we have seen in a previous posting how the desire to preserve beliefs one holds dear leads people to adopt intellectual strategies that enable them to do so.

Tim van Gelder, writing in the article Teaching Critical Thinking: Some Lessons from Cognitive Science (College Teaching, Winter 2005, vol. 53, No. 1, p. 41-46) says that the strategies adopted are: “1. We seek evidence that supports what we believe and do not seek and avoid or ignore evidence that goes against it. . . 2. We rate evidence as good or bad depending on whether it supports or conflicts with our belief. That is, the belief dictates our evaluation of the evidence, rather than our evaluation of the evidence determining what we should believe. . . 3. We stick with our beliefs even in the face of overwhelming contrary evidence as long as we can find at least some support, no matter how slender.”

In the discussions about evolution, people who wish to preserve a role for god have plenty of viable options at their disposal. They can point to features that seem to have a low probability of occurring without the intervention of an external, willful, and intelligent guidance (aka god). These are the so-called ‘irreducibly complex’ systems touted by intelligent design creationism (IDC) advocates. Or they can point to the seeming absence of transitional fossils between species. Or they can point to seemingly miraculous events or spiritual experiences in their lives.

Scientists argue that none of these arguments are valid, that plausible naturalistic explanations exist for all these things, and that the overwhelming evidence supports evolution by natural selection as sufficient to explain things, without any need for any supernatural being.

But in one sense, that argument misses the point. As long as the debate is centered on weighing the merits of competing evidence and arriving at a judgment, van Gelder’s point is that it does not matter if the balance of evidence tilts overwhelmingly to one side. People who strongly want to believe in something will take the existence of even the slenderest evidence as sufficient for them. And it seems likely that the evolution debate, seeing as it involves complex systems and long and subtle chains of inferential arguments, will always provide some room to enable believers to retain their beliefs.

But the mind/brain debate is far more dangerous for religion because it involves the weighing of the plausibility of competing concepts, not of evidence. The fundamental question is quite simple and easily understood: Is the brain all there is and the mind subordinate to it, a product of its workings? Or is the mind an independently existing entity with the brain subordinate to it?

This is not a question that scientific data and evidence has much hope of answering in the near future. Eliminating the mind as an independently existing entity has all the problems associated with proving a negative, and is similar to trying to prove that god does not exist.

But since the mind, unlike god, is identified with each individual and is not necessarily directly linked to god, discussing its nature carries with it less religious baggage, and its nature can be examined more clinically

POST SCRIPT: Choosing god

I came across this story (thanks to onegoodmove) that illustrates the point that I was trying to make on the way people choose what kind of god to believe in. I have no idea if the events actually occurred, though, or if the story has been embellished to make the point.

The subject was philosophy. Nietzsche, a philosopher well known for his dislike of Christianity and famous for his statement that ‘god is dead’, was the topic. Professor Hagen was lecturing and outside a thunderstorm was raging. It was a good one. Flashes of lightning were followed closely by ominous claps of thunder. Every time the professor would describe one of Nietzsche’s anti-Christian views the thunder seemingly echoed his remarks.

At the high point of the lecture a bolt of lightning struck the ground near the classroom followed by a deafening clap of thunder. The professor, non-plussed, walked to the window, opened it, and starting jabbing at the sky with his umbrella. He yelled, “You senile son of a bitch, your aim is getting worse!”

Suffice it to say that some students were offended by his irreverent remark and brought it to the attention of the Department Head. The Department Head in turn took it to the Dean of Humanities who called the professor in for a meeting. The Dean reminded the professor that the students pay a lot of tuition and that he shouldn’t unnecessarily insult their beliefs.

“Oh,” says the professor, “and what beliefs are those?”

“Well, you know” the Dean says, “most students attending this University are Christians. We can’t have you blaspheming during class.”

“Surely” says the professor, “the merciful God of Christianity wouldn’t throw lightning bolts. It’s Zeus who throws lightning bolts.”

Later the Dean spoke with the Department Head, and said, “The next time you have a problem with that professor, you handle it, and let him make an ass out of you instead.”

The dubious appeal of immortality

During the time I was a Christian, I took it for granted that immortality was not only a Good Thing, it was the thing that mattered most. The idea that if one believes in Jesus (or in some other way meets the needs of Christian doctrine), one is saved and has eternal life is a central tenet of Christianity. The formulation “For God so loved the world that he gave his only begotten son that whosoever believes in him shall not perish but have eternal life” is something that any Christian can recite. It makes up the famous verse John 3:16 which you will often see written on a bed sheet and draped over railings at big sporting events. (This passage is so familiar to Christians that I was able to type it out accurately after all these years without even looking it up.)

What is surprising is that despite all the emphasis on going to heaven as the main point of living, the Bible contains very few actual descriptions of the place and what people there actually do. Even the good folks at Rapture Ready, who are counting the minutes until the world ends and they get taken up, admit that they don’t have much data on this key question. Their page What Heaven Will Be Like is very brief. (Disturbingly, for me personally at least, it says that in heaven the laws of physics do not apply. Why is this information not given to students when they are deciding what to major in? In the unlikely event that I am raptured, all my years of study and work will have been wasted and in heaven I will have to learn a new trade.)

The one really concrete description comes from (where else?) the Book of Revelations and it says that everyone in heaven will live in a place called New Jerusalem, which consists of a cube of side 1,500 miles. Although large (roughly the size of the moon), it should be easy to visit friends since the Rapture Ready website says that people in heaven will be able to travel instantaneously, presumably because of their ability to circumvent the laws of physics that are such restrictive nuisances for us on Earth.

Islam is more detailed than Christianity in its descriptions of heaven. Ibn Warraq writes in Virgins? What virgins? that the Koran gives the following description:

What of the rewards in paradise? The Islamic paradise is described in great sensual detail in the Koran and the Traditions; for instance, Koran sura 56 verses 12-40 ; sura 55 verses 54-56 ; sura 76 verses 12-22. I shall quote the celebrated Penguin translation by NJ Dawood of sura 56 verses 12-39: “They shall recline on jewelled couches face to face, and there shall wait on them immortal youths with bowls and ewers and a cup of purest wine (that will neither pain their heads nor take away their reason); with fruits of their own choice and flesh of fowls that they relish. And theirs shall be the dark-eyed houris, chaste as hidden pearls: a guerdon for their deeds… We created the houris and made them virgins, loving companions for those on the right hand. . .”

So basically heaven for Muslims consists of your choice of food and drink and sex, with no negative after effects. Ibn Warraq’s article describes Muslim commentators who go into even more great detail about the sexual pleasures of heaven, seemingly written exclusively from the male perspective.

I wrote previously that asking questions like where heaven is located and how it is related to life on Earth can make belief complicated because of the scientific problems it creates. First off, how come we cannot detect heaven’s existence although we are now able to probe the far reaches of the universe? Is heaven in some parallel universe, with impenetrable barriers? But they cannot be totally impenetrable since people can get there from here. Since most people believe that people in heaven can see and hear us as we go about on Earth, that means that light and sound waves can travel from Earth to heaven, crossing the barrier. So must it be a one-way barrier? How would such a barrier work to prevent two-way transmission? (This is again the kind of question a physicist would ask, because I have trouble accepting that the laws of physics don’t apply in heaven.)

But another problem is: what is it about heaven that is supposed to make it so attractive? Most people, even if they have no explicit model to work from, envisage eternal life in heaven as where everything is very pleasant and discouraging words are never heard. But surely if everything is perfect, and people in heaven live forever experiencing neither pain nor sorrow, it also has to be dull?

And that is the key problem. I cannot conceive of any way of conceptualizing heaven that is not also mind-numbingly boring. The only way to overcome that is to think that our personalities in heaven also change so that we never get tired of unchanging perfection. (“Wow, this grape is delicious! Wow, so is the next one! And the next one!…”) But then people become boring.

For example, suppose you are an avid golfer and your vision of heaven is where you can play everyday in perfect weather. Does being in heaven mean that you hit perfect shots each time? But if you do and your opponent does too, wouldn’t that take the fun out of the game? Golf is trivial, but I cannot think of anything at all that would not get tedious very quickly if one was assured of constant success. Pleasure in life goes along with failure. Take away failure and pain and loss and I am not sure what pleasure means.

The only thing that I personally can see that is good about immortality is that I may learn the answers to some difficult and unanswered questions that may elude me in my lifetime: Is quantum mechanics the ultimate theory or is there a deeper underlying theory? What exactly happens when the quantum wave function collapses in its interaction with the observer? How can one unambiguously draw the quantum/classical system boundary? How does the brain produce consciousness and the appearance of free will? Why do so many people find Julia Roberts attractive?

So basically, my own idea of heaven is to have the equivalent of unlimited high-speed internet access and subscriptions to science journals. But even that would be boring if I had to wait around a long time for Earth-bound scientists to find (if they ever do) the answers to those questions. On the other hand, if people in heaven already know the answers to these questions and told me as soon as I got there (not that there’s much chance of that), then there would be nothing to look forward to.

I can think of many, many things that would be wonderful to experience for a very short time but all of them would bore me totally if they went on indefinitely. It reminds me of the time, soon after high school in Sri Lanka, when I had a temporary job working in a chocolate factory. I was told that we could eat all the chocolates we wanted and since I loved chocolate, this sounded like heaven, and everyone envied me. But after a week of eating chocolate, I was sick of it.

I am becoming convinced that we have pleasure on Earth precisely because it is unpredictable and transient, it is mixed with pain and failure, and we know that everything, including our lives, will eventually come to an end. We experience happiness and pleasure at moments in time, but for those moments to occur they must be preceded by periods of anticipation, disappointment, and failures. Take those things away and there is no pleasure either

It amazes me that I never asked any of these questions or thought of any of these things until now. Even during the many years I was religious, I never questioned then what form eternal life would take and whether it is such an unequivocal Good Thing after all. This is surprising because I was always curious about other things and trying to make connections.

Is there something in the way we are taught our religious beliefs that gently steers us away from these questions because they are so problematic? Why had I never probed deeply into what heaven might be like?

In the next posting, I will look at what research in cognitive science says about why we don’t ask questions or look for answers to certain questions, even when it might seem obvious that we should do so.
