Forgive this long post but Richard Dawkins was the star attraction of the Atheist Convention and I assume readers would prefer more rather than less of his presentation.

“The fact of your own existence is the most astonishing fact you will ever have to face. Don’t you ever get used to it.”

With those words Richard Dawkins launched an interesting, and less-polemical-than-the-others, talk spanning the origins of  species, of life, of the universe and perhaps of billions of universes.

The universe we live in and the fact of our existence is truly a cause for gratitude. Gratitude for our individual existence and for the process of evolution which from the blind forces of physics produces all that we know and gives it the illusion of design.

Dawkins spoke of predictability and luck as the two halves of the creative process (although, no, I don’t think he used that loaded phrase). “Natural selection is the great engine of the predictable half of what I am talking about today,” he said, while blind chance is the other half.

“If some catastrophe wiped out the mammals today, the surviving vertebrates would evolve into a similar range of ecological types.” Dawkins referred to the work of Simon Conway Morris Cambridge Professor of Evolutionary Palaeobiology who argues that humans would have evolved again if the tape of life had been rerun. Perhaps he is right, says Dawkins, although he parts from Conway Morris who uses it “as evidence for his weird belief in Christianity.”

But, said Dawkins, the predictable engine of natural selection requires luck at certain critical points, the most obviously at the origin of life (self replication coded information that influences the world) is the most obvious case. This first step in the chain of evolution might have been a very lucky step indeed. How lucky? Dawkins asked.

We don’t know. Theories of the origin of life are hardly plausible at this stage. To ask the question is tantamount to asking how many times life has arisen around the universe. Do we live in a universe teeming with life or, at the other extreme, one where life has arisen only once? “For what it’s worth, and that is not very much,” Dawkins said, “my gut feeling is that life is probably reasonably common.” But the number of planets is so vast, that even a million independent planets with life might have no contact with one another.

But one thing is clear: if you believe that life has arisen only once, then a consequence is that the event that we call the origin of life has to be of such stupefying probability that any chemist looking for it is wasting their time. Any plausible theory would result in life arising many times. Only an implausible theory would result in life arising only once in the universe.

Dawkins spoke of what physicists call the ‘fine tuning’ of the universe explaining that there are a number of physical constants such as the gravitational constant that govern the laws of the universe. He referred to Martin Rees, the Cambridge Cosmologist and Astrophysicist who wrote Just Six Numbers. These are numbers that we can calculate but which we don’t have a rationale for why they have these particular values. We might think of them as six dials that have to be set exactly right at the very beginning. Many physicists have argued that the origins of the universe and laws of physics result from a stroke of blinding luck that left each of these dials at exactly the right position. Any other setting on any one of the dials would have given a no universe result.

Dawkins rebuffs any divine conclusions from fine tuning of the universe. This is not proof of conscious intelligence he says. “To postulate a divine knob twiddler who knew the exact value doesn’t explain anything.”

Rees resorts to what is known as the anthropic principle, “which theists think is their domain,  but is deeply atheistic.” It holds that all universes that are observed must have the correct values (or there would be no observers). This can be combined with multiverse theory which holds that the one universe we observe is only one of billions of universes mutually incommunicado, all of which have different values of the fundamental constants. Now, with billions of universes with different values of fundamental constants, we can say that we live in the one that has the fine tuned properties necessary for us to be around to observe it.

Dawkins also cited a more Darwinian theory of the origin of the universe, the idea that universes “give birth to baby universes” which are slightly mutated versions of the parent. This is evolution on a universal scale where fitness is defined as the ability for a universe to last long enough to give birth to offspring. While not popular amongst physicists, Dawkins said, it’s hard to find strong objections.

From cosmology Dawkins moved back to human evolution emphasising that both seem to owe their beginnings to an enormous shot of luck. Both are wondrous, amazing and a cause to give thanks. But to whom? To providence? The gods?

What are the evolutionary roots of gratitude and of religion? The fact that such characteristics of humans seem to be universal demands an explanation. Dawkins suggested that religion might be a by-product of another predisposition. For example, the child mind is predisposed to obey authority, a characteristic which has strong survival value. But a by-product of this predisposition might be vulnerability to “mental viruses such as religion,” just as a computer is vulnerable to viruses because it has no way of knowing whether a program is good or bad.

As for gratitude, Dawkins suggested it might be the by-product of the need, prior to the use of money, to keep mental accounts of what is owed and owing. Children  early on develop a sense of fairness and in some cases it operates without a real target, for example, “it’s not fair that it is raining on my birthday.” Sexual lust too still operates although its original reproductive benefit is no longer ‘the target.’

Dawkins suggests “we have a similar lust to calculate debt, gratitude, fairness and it’s so powerful that it goes off in a vacuum.” Such psychological dispositions might also lead us to postulate God, he said. In a pastoral moment Dawkins assured us that “this sort of vacuum activity is nothing to be ashamed of” and that the first part of his talk gave sufficient reason for gratitude to be alive even though it is “gratitude in a vacuum.”

One of the questions after the talk gave the audience a lesson from the master communicator when a Christian prefaced her question about DNA with her gratitude to God. The crowd started heckling but Dawkins quietly calmed the storm and went on to answer the question with seriousness and at length.

Another questioner asked whether Australia getting its first saint would do us any harm. “That’s pure Monty Python,” said Dawkins referring to the Pope as “Pope Nazi.” And, he said, it’s the sort of thing that “gives the lie to the claim that sophisticated theologians should be able to look down on fundamentalist wingnuts. They are all the same.” [See below for a correction to this paragraph.]

When asked when he would be willing to criticise Islam as he did Christianity, the response was pragmatic. “I personally believe we shouldn’t go out of our way to do things that will get our heads cut off.” To the Islamist he would make it clear that this reticence is “because I fear you. Don’t think for one moment it’s because I respect you.”

A question about how to talk to Christians “when let’s face it we think we are smarter than them?” brought the following reply and applause from the audience: “We aren’t necessarily smarter than them. Respect them and honour the reasons why they believe.”

Another question about the differences between atheism and agnosticism was answered: “I don’t actually call myself an atheist in that sense: I’m a 6.9 on the scale of 0 to 7. We are all agnostic about almost everything. I’m an atheist in the same way I’m afairyist.”

And: “Might there be a chink in my arguments? Of course there are all sorts of chinks, but the onus is on those who want to believe in religion. … It’s odd that people who in everyday life use perfectly logical reasoning don’t do so when it comes to religion… Religion certainly poisons your ability to use your brain.”

Overall an interesting talk with vitriolic moments but less polemic than I expected and tempered with the mellifluous tones of an Oxford don.

[Correction: After listening to an audio version of Richard Dawkins' answer it seems clear that when he used the phrase 'Pope Nazi' he was not referring to the current Pope but to Pope Pius XII, the Pope during the Second World War. Click here for the question and Dawkins' response.]
