Atheism is apparently not anti-evolutionary after all

Last week The Times splashed a claim that new research by a British psychologist found that belief in God is intuitive and may be hardwired by evolution. The article included quotes from Bruce Hood, professor of developmental psychology at Bristol University, who told the journalists that his research “shows children have a natural, intuitive way of reasoning that leads them to all kinds of supernatural beliefs about how the world works.” The article claimed human tendency towards supernatural beliefs explains why many become religious as adults, despite not having been brought up within any faith. It claimed scientists believe that the durability of religion is in part because it helps people to bond. (pic adapted from original by stuartpilbrow)

As is often the way with journalism, the article was something of a simplification, not least with the words of Bruce Hood. Writing on his own blog two days later, Hood said he was misrepresented. Hood’s point, which he told The Times, was that humans are born with brains to seek out patterns and infer hidden mechanisms, forces and entities. “That does not make me either religious or a religious apologist,” he said. But Hood’s statements did not fit in with the “Born to Believe in God” angle the paper was pushing and his words were twisted and The Times’s angle was repeated by the Mail Online and the Telegraph.

In the rush to prove that religion was hardwired by evolution, the media glossed over what Hood actually said. He did not say humans evolved to believe in God. Instead, he agrees with Richard Dawkins that religion is a cultural construct. However he doubts that supernatural beliefs can be eradicated by education. The power of beliefs is strong and quite often is a positive force. Life is a balancing act between trusting our beliefs enough to act on them without being so certain about them that we could never ditch them. That predisposes the idea that we act on fallible beliefs. For instance, we cannot wait for all the evidence to come in before we act on global warming.

Nevertheless belief is predicated on a set of assumptions about how the world operates. This construct is central to all of the world’s major religions and has been so ever since humans prayed for rain or sunshine. But absence of belief has long been around as a counteractive force even if atheists were usually treated with scorn, or worse (rhe term comes from the Greek “atheos” meaning “deserted by the gods”). But according to Richard Dawkins we have all deserted the ancient Gods and atheists have simply gone one God further.

But evolutionary biologist David Sloan Wilson believes atheism is a stealth religion. He dubbed Dawkins and Christopher Hitchens “the New Atheists” and said the movement forming around Dawkins in particular was a religion without supernatural agents. For the new atheists, faith is a heresy that must be stamped out. But in truth they are part of an old tradition that goes back two hundred years to when atheism split between those who are primarily concerned with the pursuit of truth and those who are driven by contempt of those who have faith. For those in the latter camp, the fact that citizens could worship their gods in peace supported by the state was an indefensible concession to superstition and prejudice.

Some Christians have gone on the counter-attack and have attempted to demolish atheism’s intellectual credentials. Among the best known of these is Alistair McGrath’s The Twilight of Atheism. McGrath’s book defines atheism not as a suspension of decision but as a principled decision to live and act on the assumption there is no God or any spiritual reality beyond what we know. He says it was inspired by Protestantism which encouraged people to think of a world in which God cannot be experienced. Atheism thrives when Christians get into power and abuse it. But says McGrath, the 20th century godless world of the Soviet Union eroded the imaginative potential of atheism.

But such arguments are unimportant to secular societies such as Australia. The nation’s census doesn’t ask about atheism but the numbers of those who admit to “no religion” are low. From 1901 to 1971, the figure was almost negligible. But it has been rising steadily since and is now 18.7 percent. But active participation in religion is also low. Just 20 percent of adults participated in religious or spiritual groups or organisations in 2006. What the data shows is that materialism rules in this country though people may not necessarily admit to it in census questions.

One category definitely not on the census list is “soft cock atheist”. This is the odd category the author known as “Godless Gross” chose to describe himself in when writing in yesterday’s newly revamped National Times (though unnamed, it is reasonable to describe the writer as male on the evidence). Gross said he represented a “wishy washy” strain of atheism that could easily be swayed into theism if the right faith came along. The author also claims we are “a religious species” with 86 percent of people worldwide believing in some kind of God or other.

But perhaps what we need to become is more of a secular species. Secularism doesn’t necessarily take a side on religion. According to Max Wallace, head of the National Secular Society, the defining characteristic of secular government is separation of church and state. He says that despite the US’s predisposition for creationism (noted again today by a new British film about Darwin which cannot find an American distributor), that country’s government has a better separation than the constitutional monarchy of Australia. Religions get tax exemptions but atheism does not because it is not a form of supernatural belief. Wallace reminds us our government is a soft theocracy “but with a secular twist according to political contingency.” So which is worse, a soft theocracy or a soft cock atheist? God only knows.

Spain gives human rights to great apes

Spain is likely to pass a law giving great apes human rights to life and freedom. Last month a parliamentary environmental committee urged the government to give rights to the closest genetic relatives to humans. With cross party support, it managed to commit the Spanish Government enact a law within 12 months to outlaw harmful experiments on apes. The committee modelled their plan on the declaration of the “Great Ape Project” which has the backing of scientists and philosophers.

The declaration affords rights equal to humans for all the other great apes: chimpanzees, bonobos, gorillas and orang-utans. It promotes the right to life, the protection of individual freedom and the prohibition of torture. The Great Ape Project was founded 15 years based on a book of that name by the philosophers Peter Singer and Paola Cavalieri.

In 1993, Singer and Cavalieri wrote about the rich emotional and cultural lives of non-human great apes. The book recommended the creation of an international body for the extension of the moral community to all great apes. The book compared the slave trade in human and non-human ape societies and expanded the boundaries for legal rights for the other apes based on the evolution of hominids.

Hominids emerged out of the Great Rift Valley. The valley was formed 15 million years ago in a tectonic parting of the ways that stretched 10,000 km from Lebanon’s Beqaa Valley through the Dead Sea, the Red Sea and down to the Great Lakes of Africa that fill its crevasses. Along the rift, are active and inactive volcanos, as well as lakes, deserts and plains. In places, the valley floor is lower than sea level. The crack is widening and will eventually rip Africa apart. But for the now the valleys teem with life.

The Rift is also a theatre of death. At Olduvai Gorge, in what is now Tanzania, archaeologists Louis and Mary Leakey found fossilised hominid skulls some 1.75 million tears old. Mary Leakey would go on to find footprints frozen in wet ash by hominid parents and their child fleeing an eruption that took place almost 4 million years ago. The long lifeline between Ethiopia and Tanzania was the home of human forebears for millions of years before they reached down to pick up a tool.

The valley is also home to many of the great apes including the chimpanzee. Seven million years ago, the common ancestor of chimps and humans lived in the forests of the valley. But no fossil record exists of this creature. Heavy rains leach minerals from the tropical forest grounds before anything can fossilise. But genetics show this creature exists. American physical anthropologist Richard Wrangham gave this ape a name: Pan prior.

The name meant ‘prior to Pan troglodytes’ the scientific name for chimps. Wrangham and others believe that climate change seven million years ago caused an ice age that dried up Africa. One branch of Pan priors moved on to the savannah in a desperate measure to survive. By the time the planet warmed again, these grassland dwellers preferred to stay in the open. While they had lost its ability to live in trees, they had picked up new skills on the savannah.

Those that stayed in the forest evolved into chimpanzees. They are exceptionally bright creatures and superb hunters. Their successful kill rate of 80 percent compares well to the 10 to 20 percent of lions. But like humans, they are also extremely brutal to each other. They will launch raids in other clan territories. There, they will ambush unwary lone males and maul him to death. Once they have carefully picked off all the males in this way, they will claim the females of the territory. Fights will then break out to determine the alpha male in the group.

Much of chimp behaviour is disturbingly similar to human behaviour. To give them the same rights as humans is reasonable, if a little perplexing in Spain which has no native great apes. But the ruling is also likely to be a shot across the bows of other animal related industries, including the bullfighting lobby. Certainly that’s how Pedro Pozas, the Spanish Great Apes Project director, sees it. He said that the vote would set a precedent, establishing legal rights for animals that could be extended to other species. “We are seeking to break the species barrier,” he said. “We are just the point of the spear.”

Richard Dawkins: Evolution and Creationism

In the first part of The God Delusion, Richard Dawkins looked at the phenomenon of Lourdes. Dawkins describes religion as turning untested belief into unshakable truth through the power of institutions and the passage of time. According to Dawkins, this was testament to the power of tradition in religion.

Dawkins examined the Assumption of Mary to hammer home his point. According to Catholic theology, Jesus’ mother Mary did not die, she ascended directly into heaven at the end of her life. There is no evidence for this; it is not mentioned in the bible. The belief she ascended into Heaven emerged in the 6th century AD. The story spread by word of mouth and became established tradition. The longer it kept going, the more it was taken seriously. In 1950 it became authority. The Vatican decreed Catholics must believe in the doctrine of the Assumption of the Virgin. This doctrine was ‘revealed’ to Pope Pius XII by God.

While Catholic doctrine over the assumption of Mary is not in itself harmful, the Pope’s personal convictions about discouraging the use of condoms in Aids-ridden Africa is another story. Here there is an appalling human cost. The Church uses its authority to issue edicts to the faithful without a shred of evidence to back their claims. But Dawkins is at pains not just to blame the Catholics. Fatwas by Muslim imams follow the same trajectory.

Religion thrives on unsolved mysteries. For early humanity what was mysterious and unexplained was so vast, it needed a higher being an ‘alpha male in the sky’ to explain it all. Scientific investigation has rolled back many mysteries. Where once were Sun Gods, science now tells us the Sun is middle-sized star halfway through its 10 billion year life. Revolving round it is the 4.5 billion year old Earth. Science has used evidence, comparing and corroborating evidence, to update old theories about how things work.

Humanity used to resort to supernatural hypotheses for creation myths. Genesis is one of many such myths. God fashioned the world in six days. In the 19th century Charles Darwin hit on what really happened, without any need to invoke the supernatural or the divine. Evolution is a gentle slope; Darwin’s great insight was that life evolved steadily and slowly over four billion years. Natural selection not a divine designer was the sculptor of life. The design hypothesis raises an even bigger problem than it solves: who designed the designer?

Dawkins thought that in his lifetime evolution would be accepted as fact everywhere, backed up as it is by overwhelming evidence. But this evidence cuts no ice with many. Evolution today is under threat. In the bible belt of Middle America, evangelicals are fighting back against science. In the new world, religion is free enterprise. Rival groups set up shop competing against each other to save souls. Fundamentalist Christianity is on the rise in the world’s only superpower. Its power spreads up to and including the president. 135,000 million Americans believe the universe is less than 10 thousand years old.

Dawkins goes to the New Life Church in Colorado Springs where conservative Christians have built an $18 million Church. New Life isn’t just a church but a social network. A 12,000 congregation attend 1,300 organised programs which guide them on everything from marriage to dog walking. It is a New Jerusalem in the foothills of the Rocky Mountains. While it lacks the tradition of Lourdes, it makes up for it in swaggering authority.

Evangelical churches like this have become enormously powerful in the US influencing everything from the teaching of science in schools to foreign policy. New Life Church Pastor Ted Haggard was a powerful man, chairman of the National Association of Evangelicals. Haggard had a hot line not only to God but also to President Bush. He is a staunch Republican. He had also rubbed shoulders with Tony Blair and Ariel Sharon. Dawkins was not to know that Haggart was forced to resign in November 2006 after paying for sex with a gay prostitute and admitting he bought drugs.

When Dawkins and Haggart met, they clashed on the Bible. Dawkins wanted to understand what he called ‘irrational faith’ is spreading and attacking science. In their interview Dawkins began by complimenting Haggart and suggested a lot of money was spent here. Haggard said “I wanted people to be able to worship and enjoy it and be in a setting where the speaker is close to them…so I can look at them”. Dawkins said this was effective and said the sermon reminded him of the Nazi Nuremburg rallies. Haggard laughed and said lots of Americans think of it more as a rock concert.

Dawkins acknowledged that every person needs at the centre some sense of meaning about existence. But most accept that life is complex not the childish certainties of God. Dawkins biggest concern is that evangelicals like Haggart are foisting falsehoods on their flock. They deny scientific evidence just to support a Bronze Age myth. Haggart hit back by accusing “people like Dawkins” of intellectual arrogance and air of superiority because “they know so much more”.

Haggart’s approach is to lets teach evolution as just another theory alongside creationism and intelligent design, which sounds reasonable on first impression. But whereas evolution by natural selection is supported by mountains of evidence, creationism exists on a flimsy base; self-contradictory and supported only by what Dawkins contempuously calls "ancient scribblings".

The Intelligent Design hoax

In the 19th century science was posing a huge threat to religion. Biblical authority and church teachings which had first taken a hammering with Galileo’s theories were now under siege. Geologists had shown that the Earth was very old indeed. Darwin’s Origin of Species in 1859 was followed by the Descent of Man in 1871 and both books advanced a theory of evolution that was at serious odds with the established view of a Creationist world.

By the 1870s, nearly all biologists agreed that life had evolved, and by the time of the Second World War most agreed that natural selection was a key force driving this evolution.

The churches and the powers-that-were didn’t take this challenge lying down. There was always the view that Darwinism represents a thinly veiled attempt to foist a secular religion—godless materialism—on Western culture.

According to a 2001 Gallop poll 45% of Americans concurred with the statement that "God created man in his present form within the last 10,000 years”. But it is harder to sustain outright belief in Creationism in the face of increasing scrutiny of biblical evidence.

In recent years, the Creationists have taken a new tack and have come up with a more sophisticated, pseudo-scientific and beguilingly named product called Intelligent Design. Slickly marketed, it is now the front face of creationism. It has very powerful friends.

US President Bush supported teaching alternatives to evolution in public schools with remarks such as schoolchildren should be taught about intelligent design as well as evolution. He said in August 2005 "Both sides ought to be properly taught . . . so people can understand what the debate is about. Part of education is to expose people to different schools of thought. . . . You're asking me whether or not people ought to be exposed to different ideas, and the answer is yes.”

The theory of intelligent design holds that life and the universe are best explained by an intelligent cause rather than an undirected process such as natural selection. It deliberately does not try to identify or name the specific creation but many of its proponents state that the designer is the Christian god.

The idea is far older than Darwinian evolution. The first recorded arguments for a natural designer come from Greek philosophy. Heraclitus is associated with the philosophy of Logos which describes human knowledge and the inherent rationality of the universe. Plato spoke of a “demiurge”, a deity of supreme wisdom and intelligence who created of the cosmos. Aquinas posited the supernatural designer of the universe in the 13th century. In 1802, English theologian William Paley wrote “If we find a pocket watch in a field, we immediately infer that it was produced not by natural processes acting blindly but by a designing human intellect.” It arose again in the early 1980s with the publication of The Mystery of Life's Origin by creationist chemist Charles Thaxton.

The leading proponent of Intelligent Design today is American biochemist Michael Behe. He advocates the idea that life is too complex at the biochemical level to have evolved. The trigger for his involvement was the 1987 decision in the U.S. Supreme Court barring the teaching of Scientific Creationism from public schools. In his book “Darwin’s Black Box,” Behe maintained that irreducible complexity presents Darwinism with “unbridgeable chasms”.

The Christian think-tank The Discovery Institute was set up in 1990 and is a driving force behind Intelligent Design. Their mission statement is “to make a positive vision of the future practical”. Their agendas are to promote public awareness, lobby for teaching in high schools and instigating pro Design legal actions. They have powerful friends. The Gates foundation has pledged $10 million since 2000. Its major contributors are also the same major contributors to George W. Bush.

The idea is to present evolution as a ‘theory in crisis’ and to poke as many holes in it as possible. The mathematician William Demski, another proponent of ID, holds the concept of specified complexity. When something is both complex and specified, one can infer that it was produced by an intelligent cause. He provides the following example: "A single letter of the alphabet is specified without being complex. A long sentence of random letters is complex without being specified. A Shakespearean sonnet is both complex and specified”.

Despite the rhetoric, many critics say that intelligent design has not presented a credible scientific case. Instead it is seen as an attempt to teach religion in public schools and intelligent design has substituted public support for scientific research. The theory has little support in the scientific community. In October 2005 a coalition of 70,000 Australian scientists and teachers stated "intelligent design is not science" and called on "all schools not to teach Intelligent Design (ID) as science, because it fails to qualify on every count as a scientific theory”.

To date, the intelligent design movement has yet to have an article published in a peer-reviewed scientific journal.

In 2004, the school board of Dover, Pennsylvania, voted to require the teaching of intelligent design alongside evolution in science classrooms. On December 20, 2005, U.S. District Court Judge John Jones ruled that the school district cannot follow through with its plan because it would violate the Constitutional separation of church and state. In his opinion Judge Jones wrote, "We have concluded that it is not [science], and moreover that ID cannot uncouple itself from its creationist, and thus religious, antecedents".

It remains a dangerously powerful and popular bunkum. Intelligent Design is science’s equivalent of junk food. It is the newest evolution of Creationism and teaches us more about politics and religion than science.

It is no more scientific than those who write to the Kansas School board which was leaning towards Intelligent Design. The protesters state that they are of the strong belief that the universe was created by a Flying Spaghetti Monster and it too should be considered for the curriculum. It is as scientific and more amusing.
