Dad Tip: Teaching Evolution

[I am thinking this will be a semi-regular thing on my blog now. Sure I am not the greatest Dad in the world, and my experience is limited to a single son; but at the end of the day every little step along the way is an important one, and perhaps some of my experiences will have merit beyond my own doorstep. Let me know what you think in the comments below.]

In my six odd years of having a son, I have discovered that one of the hardest things to try and explain to him is the concept of evolution. I see this as a bit of a problem, as being a dinosaur nut like his old man, evolution is vital to his understanding of these creatures.
From our recent trip to the Melbourne Museum, where Harrison could finally tell me most of his favourite dinosaur's names. #DadPride
This problem can be doubly difficult because at its most basic level, the theory of evolution is a very simple concept, however it relies on a lot of concepts and grounding that is just out of reach of young children.
Saying to your child that evolution is how animals change over time to adapt to their surroundings can lead to a lot of misunderstandings of how exactly they change, and how they adapt. I often found myself getting exasperated trying to explain through simple examples such as a giraffes neck; explaining how having a longer neck helps them reach higher food, but then being sure to stress that the individual didn’t get a longer neck because they want one, but that their children, if born with a slightly longer neck, will pass that trait on down.
Before you know it, your explanation has gone on longer than you wanted it to, and has included too many new words and concepts for your child to really stick to the point.
Don’t get me wrong, my son is one bright kid. Ask him what light is made of and he has two answers; a joke one (light is made from torches), and the real one (light is made of photons). It is just that getting kids’ minds to work on the scale of evolution takes a lot of mental effort on their part. Kids very rarely want to think of the consequences of their actions beyond the days play, let alone the consequences of animal’s actions across the generations.
Over the years my son’s understanding of the natural world has progressed quite well, and I am very proud when he talks about biological features as evolved, and ponders what their purpose is in helping the animal survive. But it was just the other day when we were discussing evolution (yes this is what my son and I do sometimes) that I hit on a better way to explain it to him.
I don’t quite recall how we got onto the subject, but I shocked Harry by telling him that our dog was descendant from wolves. Now perhaps this isn’t the most surprising fact for a child, but consider my dogs appearance:
This is why when i write of my dog, i often put inverted commas around the word 'dog'....
 That’s a wolf?!” He exclaimed (with an inflection well worthy of an interrobang).
I explained that back when man was still living somewhat in the wild, we domesticated wolves for companionship and to help make our lives easier.
I reminded him that a lot of traits in animals can be inherited from their parents (he is aware that he got half his DNA from me, and the other half from my wife, but luckily he hasn’t asked how they got mixed yet…), then asked him what would happen if we picked the ‘nicest’ wolves, got them to have babies, and then keep picking the nicer, friendlier, ones to have around us. He was pretty quick in understanding how these traits could be selected, and bred into the population. It was working a treat.
Next example I used was the domestication of the cow. I explained how we domesticated them from Aurochs, creatures that were twice as big, and quite nasty customers. Picking the smaller, more docile ones each time and having only those in your paddock, I was able to show how this selection can likewise change a population over time.
Perhaps I should have caught onto utilising artificial selection as a way of explaining this long ago after all Charles Darwin, the great man himself, used this introduction to his theory of evolution in On the Origin of Species.
Once this fundamental concept is understood, it is pretty easy to cross from artificial, to natural selection. All that has to be explained then it how animals in the wild aren’t selected by people because of the traits they want to propagate, but instead the individuals are ‘selected’ by nature, because they are the ones that survive better and have more kids.
It is a great feeling to see that you have successfully explained something to your kids, when you see that little click of comprehension, and the pride they feel having learnt something new. The only thing that worries me now is that he is garnering all of this information at a rate that much exceeded my own at his age. If our generation isn’t careful, these guys will be taking over in twenty to thirty years……

Dawkins v Pell: My Commentary

I have been away for the Easter holidays (which in some part explains my lack of blogging lately), but was delighted to find that as I came home Monday night, there was to be a televised sparring between the venerable Richard Dawkins, and the........ well, and George Pell.
It is always great to see Dawkins on the fly. So often news reports depict him as a militant atheist, who is rude, or arrogant, and attacks religious belief with wanton disregard. Then when I watch his appearances, I am always reminded of just how polite and British the man is. His worst retorts after all are generally along the lines of an Oxfordian “utter nonsense”, or “patently absurd”.
If this is considered the epitome of a rude atheist, then I must be a positively abhorrent one.
During the show I was surprised at how flimsy Pell arguments were. No doubt I was always going to come out in support of Dawkins, but I had expected there to be more formidable arguments either for religious belief, or else against atheism. Yet I found myself being able to predict the weak arguments before they were pulled out of what must be quite a tattered bag of apologist tropes.
Hitler was an atheist, or social Darwinist; therefore evolution can’t be a good thing. We evolved from Neanderthals. If there were no justice after death, that would be very nice, therefore, there must be. Darwin was a theist. And so on.
All in all I had a great time watching the show, and though I had promised myself that I wouldn’t go into a twitter overload, I ended up tweeting around 22 times during the fifty-odd minute show. Not too bad an outcome though, as I managed to get one of my tweets up on screen to be seen by 863,000 Australians, which is around 4% of the population, so I am happy with that. It also got me a sizable new chunk of followers on twitter, and it is always nice to know that your crazy twitter rants are appreciated.
Then as I decided to write a blog on this episode of Q&A, I quickly found my initial thoughts on the program spiralling out of control into an almost blow by blow account of the interaction. So rather than make this solely a reflective piece, I have decided to make it a sort of running commentary of my favourite bits of the night, supplemented with quotes from the transcript.
This ended up running into around five thousand words (I remember uni days when such a word count would have killed me), but I hope it is somewhat entertaining for those of you who watched the show, and perhaps even those who missed it.
So yes it is rather longer than my usual posts, and doesn't have as many interesting pictures to look at, but it is just a culmination of a lot of stuff i wanted to get off my chest after watching the show.
Here goes.



The first question was quite a stock standard one, regarding whether or not an atheist can essentially be a good person. It is one often brought out in these debates, but also one that most people know the answer to from either side; yes, but with some conditions.
Dawkins points his response that “it is true that Christianity has adopted many of the best values of humanity but they don't belong to Christianity or any other religion”, and goes on to point out the bad things espoused in the Bible, both New Testament and Old. Then Pell counters with a quote which seems to me a bit too understanding of Christianity’s nature as a created religion, not a metaphysical truth:
“We’re Christians, we're New Testament people. There was an evolution in the Old Testament. There are some awful things there. It developed. The notion of God was purified as it went through the Old Testament.”
It seems odd for him to be talking of the notion of God changing, and of parts of the Bibles teachings being awful.
Now on to audience question number two, where things start to get moving along quicker:
“Religion is precisely often blamed for being the root of war and conflict but what about all the good it has done for society. God-centred religion has been the birth place of schools, universities, hospitals and countless developments in science. Richard, if you believe the human drive to seek the truth and to constantly improve ourselves is merely a mechanism for survival, then what’s the point and why should I bother? ”
This second question was a bit all over the place. First it is talking about remembering all the good things that religion has done rather than focusing on the bad things, then after simply stating that as if it should be a powerful point, the questioner quickly darts aside and asks ‘what’s the point’ if we are products of evolution.
I mean, perhaps a pertinent question, but where is the lead up, and what’s more; where is the alternative? It is all well and good to say, ‘what is the point if we are the product of evolution’, but perhaps if you are arguing for religion as the alternative, you should at least offer a reason why us originating from a god’s creation would imbue us with any more purpose, beyond that of merely being created by a god.
As Dawkins said “We have to find our own purposes in life, which are not derived directly from our scientific history”, which I agree with completely because I think that any purpose we want to derive for ourselves should depend on our own qualities and attributes, not just our physical origins.
Pell isn’t brought into the debate here, which was a pity if we wanted to hear an alternative purpose of life. But nonetheless, the third question quickly followed as a bit of an extension of this:
“Okay, my question for you today is: without religion, where is the basis of our values and in time, will we perhaps revert back to Darwin's idea of survival of the fittest? ”
Having read a lot of Dawkins writings, I knew he would have an answer for this which really seems like common sense to anyone who understands science’s place in our lives. That answer is simply that Darwinian principles explain how we got here; they are a physical law and shouldn’t be used to determine how we run our society any more than the theory of gravity should. Dawkins says this, and states emphatically that he would definitely not like to live by Darwinian principles.

The discussion then went towards science, and how it can tell us about why we are here. Pell, being a self stylised authority on why we are here, leapt on this chance, which lead to this little exchange:
GEORGE PELL: Well, it’s interest because I think in the space of about two minutes, Richard has said two different things, one of which is that science can't tell us why we're here and then in the next minute, trying to say that it does.
RICHARD DAWKINS: No. No. I said it can tell us why we're here.
GEORGE PELL: It can't.
RICHARD DAWKINS: Well, I simply contradict you in that case.
Here we begin to see the germ of a core misunderstanding between Pell and Dawkins as one talks about why we are here in a sense of ‘what is our purpose’, and the other talks about why we are here in a sense of ‘what caused us to be’.
Dawkins put it nicely, and with his trademark scientific air:
“Why we exist, you're playing with the word “why” there. Science is working on the problem of the antecedent factors that lead to our existence. Now, “why” in any further sense than that, why in the sense of purpose is, in my opinion, not a meaningful question. You cannot ask a question like “Why do mountains exist?” as though mountains have some kind of purpose. What you can say is what are the causal factors that lead to the existence of mountains and the same with life and the same with the universe.”
This is the age old ‘science can answer how, but not why’ argument, where those in favour of this rhetorical side step fail to elucidate why there must be a why, as opposed to simply just a how.

Then, at around the 9 minute mark I believe it was, Pell proved himself to be quite a premature invoker of Godwin’s Law when he took what is considered a fatal step in internet arguments, and committed a Redictio Ad Hitlerum:
“[...] it’s not Maggie Thatcher who was in the epitome or the personification of social Darwinism. It’s Hitler and Stalin. [........] Because it is the struggle for survival, the strong take what they can and the weak give what they must and there is nothing to restrain them and we have seen that in the two great atheist movements of the last century.”
Not only is this a premature appeal to Hitler, but also the classic mistake of counting him, and his Nazi cronies, as vanguards for atheism. Dawkins of course being a veteran of these unctuous arguments was quick to label this as ridiculous and again pointed out that:
“That’s exactly why I said that I despise Darwinian natural selection as a motto for how we should live. I tried to say we should not live by Darwinian principles but Darwinian principles explain how we got here and why we exist in the scientific sense”
At this point we reach the first of a few instances where a group of the audience flat out laughed at sporadic points during Dawkins explanations, to which he would ask the audience ‘Why is that funny?’ but never got a direct response. The laughter in this case was caused by the statement from Dawkins:
“Now, Cardinal, you said it’s part of human nature to want to ask the question why in the sense of purpose. It may very well be part of human nature but that doesn't make it a valid question.”
They laughed, Dawkins asked why, but I don’t think he got a response.
As this went further, and Dawkins further explained why he believes that a question like “What is the purpose of the universe?” is a silly question, Pell interjected to say “I think it’s a very poignant and real question to ask, “Why is there suffering?””.
Well it may be poignant, and real; but it has nothing to do with the question they were talking about!
On talking about suffering Dawkins later pointed out that “it is a natural part of the living condition. It is a natural part of Darwinian natural selection, which is one of the reasons why I was so keen to say that I didn't want to live by Darwinian principles.”
Again a clear explanation of what he believes to be the place of science and evolution in human affairs, but one which is constantly ignored by his detractors.

Next a question was directed toward Dawkins about his use of the label ‘atheist’ despite the fact that he has self-identified as being an agnostic in the past. Even Tony Jones seemed uncharacteristically uninformed about this distinction, but Dawkins seemed to explain it rather succinctly (with examples from his book The God Delusion), and a nice reference to the Easter season we find ourselves in:
“I live my life as though there is no God but any scientist of any sense will not say that they positively can disprove the existence of anything. I cannot disprove the existence of the Easter Bunny and so I am agnostic about the Easter Bunny. It’s in the same respect that I am agnostic about God”
Though I was happy to see the whole agnostic/atheist thing brought up with regard to Dawkins beliefs, I couldn’t help but think it could have been handled a bit better. I am of the ilk that describes ourselves as agnostic-atheists; we don’t believe in god, but we also don’t claim to know that there is no god. The label agnostic can be applied to any number of propositions, as Dawkins points out, as it deals with claims of knowledge. Atheist however can only be applied to one proposition, namely ones beliefs regarding deities. It deals only with these beliefs, and not the nature of whether or not the validity of such beliefs can be known with absolute certainty.
It is in this way that I think it is pertinent that we use the label atheist to describe ourselves, rather than just agnostic, as it gives a true indication of what our beliefs are, not just how certain we can claim to be regarding them.

The discussion then went towards what proofs would sway Dawkins mind, to which he had no direct answer, and was open in admitting this and the questions tricky nature. Tony then asked Pell whether he would be able to provide Dawkins with some of the proof he would require, to which Pell replied:
“No, because I think he only accepts proof that is rooted in sense experience. In other words he excludes the world of metaphysics, say the principle of contradiction, and he excludes the possibility of arguments that don't go against reason but go beyond it.”
Arguments that go beyond reason....... I don’t know what to make of this.
Tony then presses Pell a bit further with a great question regarding why this god would choose a small group of Jews 2,000 years ago, and make no subsequent proof after that. George Pell then digs himself a nice little hole to sit in when he remarked that the Jews were intellectual inferiors to their contemporaries, which led to a bit of ribbing by the host:
GEORGE PELL: They weren't intellectually the equal of either the Egyptians or the...
TONY JONES: Intellectually?
GEORGE PELL: Intellectually, morally...
TONY JONES: How can you know intellectually?
GEORGE PELL: Because you see the fruits of their civilisation. Egypt was the great power for thousands of years before Christianity. Persia was a great power, Caldia. The poor - the little Jewish people, they were originally shepherds. They were stuck. They’re still stuck between these great powers.
TONY JONES: But that’s not a reflection of your intellectual capacity, is it, whether or not you're a shepherd?
GEORGE PELL: Well, no it’s not but it is a recognition it is a reflection of your intellectual development, be it like many, many people are very, very clever and not highly intellectual but my point is...
TONY JONES: I’m sorry, can I just interrupt? Are you including Jesus in that, who was obviously Jewish and was of that community?
GEORGE PELL: Exactly.
TONY JONES: So intellectually not up to it?
Bazinga!

The next viewer question was my favourite, so I shall show it in its entirety, as well as link to it:
“Question for Richard Dawkins. The big bangers believe that once there was nothing, then suddenly, poof, the universe was created from a big bang. If I have nothing in the palm of my hand, close my fingers, speak the word bang, then open my fingers again, still I find there is nothing there. I ask you to explain to us in layman's terms how it is that something as enormous at the universes came from nothing? ”
First of all, Big Bangers; I love this label.
I like his little experiment, and the challenge he puts forth as if he has shook the foundations of the Big Bang theory, but at the end of the day this guys argument about closing and opening his hand is as laughable as the old ‘Peanut butter proves that there can be no abiogenesis’ argument.
I still cant believe this guy is serious.....
I also have to ponder why it is he thinks that the enormity of the universe would impact on its ability to come from nothing. This is particularly important to note as after all, the Big Bang theory tells us that the universe was once super condensed, and as such was not all that enormous (though still contained all the energy/mater we have today apparently).
People want a simple answer for the beginning of the universe, and then balk at the mention of anything that might sound a bit beyond their understanding. If an answer cannot be understood by them intuitively, then they don’t believe it has any weight as an explanation, This may well be a good argument if you think you live in a world where such explanation usually are intuitive. But talk to any physicist and you will soon find that much of the way the world works isn’t intuitive; just Google quantum mechanics and you will see how far the rabbit hole goes.

When the discussion continues and talk of new theories regarding the appearance of the universe gets moving, Pell attacks some of Dawkins arguments, and invokes what must be one of the biggest cop out arguments in the arsenal of the Christian apologist:
“he dumbs down God and he soups up nothing. He continually talks as though God is some sort of upmarket figure within space and time”
‘Within Space and time’ is the important part there. You will constantly hear people saying that their god is outside of space and time, and thus not subject to its ways, but you never hear an explanation of what this means, and how it can be reconciled with other forms of thinking prevalent in their theology. For instance, if this god is outside of space and time, how can he create a universe? The very act of creation requires time to already exist, after all you can’t have a ‘before and after’ the universe, without having time. And you can’t have a universe, without having space-time.
Regarding the outside of space and time excuse, Dawkins replied:
“it is no good invoking Thomas Aquinis and saying that God is defined as outside time and space. That’s just a cop out.”
FYI, I didn’t realise Dawkins phrased this almost exactly as I did above, but I am nonetheless pleased by it.
I think some more direct audience participation with Dawkins would have been good. After all, so many times when the audience laughed at something he said, Dawkins wanted to know why it was funny, but received no explanation. It made him seem more offended by their laughter rather than genuinely curious and ready to engage, as I believe he was.
This second bit of audience participation was spurred on by this remark:
RICHARD DAWKINS: You can dispute exactly what is meant by nothing but whatever it is it’s very, very simple.
(AUDIENCE LAUGH)
RICHARD DAWKINS: Why is that funny?
GEORGE PELL: Well, I think it’s a bit funny to be trying to define nothing.
Of course you do George, because you are not a philosopher or a scientist, so you don’t have to define or describe things; you are a theologian, and as such simply have to interpret things within your own stationary worldview. The Cardinal talks as if definitions in a philosophical or rational debate aren’t worth ruminating over.
The audience members who were snickered here no doubt consider such things equally absurd, because like most philosophical debates worth having, there is an instinctive answer that some are just willing to accept. We think it is silly to try and define nothing, because we have our own understanding of the word built up since we were a child. Much like if people are asked to define what happy is, or sad, they will probably shy from the task, because rather than question their own personal understanding of the concepts, it is easier to treat them as self-evident truths and be done with it. Perhaps more pragmatic, but by no means philosophically satisfying.

Next came one of Pell’s biggest slip-ups which unfortunately I believe wasn’t properly debunked. That is Pell’s insistence that Charles Darwin was a theist.
The exchange went like this:
GEORGE PELL: Darwin was a theist because he said he couldn’t believe that the immense cosmos and all the beautiful things in the world came about either by chance or out of necessity. He said, “I have to be ranked as a theist.
RICHARD DAWKINS: That just not true.
GEORGE PELL: Excuse me it’s...
RICHARD DAWKINS: It’s just plain not true.
GEORGE PELL: It’s on page 92 of his auto biography. Go and have a look.
Dawkins displays his incredulity at this falsehood, but as the discussion is quickly moved along by Jones; there is no real room for rebuttal. But there is room on this blog for all manner of things I would wish to rant about, and so here I shall!
In a sense Pell is right about Darwin having been a theist, however not in the sense he actually wants people to believe. Darwin was a theist, much like he was a baby: but then he grew up. He was a theist, but then he lost this faith, and the quote in his autobiography as reference by George was clearly talking about beliefs Darwin had had, not ones he maintained at the time of writing. In fact if he had only read a few pages further, to page 94, he would have read Darwin affirming himself as an agnostic, and then elucidating just how one can go about living according to this, without recourse for a god to explain things.
The night of the show I looked up page 92 of his autobiography and got a nice link to Darwin’s online writings. However if you search for a similar thing today, you will find links to heaps of blogs discussing the very thing I am discussing now; the use of this by Pell on Q&A. The misinformation patrols are quick at work for our religious friends however, as one Catholic site is already exclaiming “Cardinal Pell shows up Richard Dawkins ignorance about Charles Darwin”.
Then, having failed to understand the history of Darwin’s religious beliefs despite the fact that he was claiming to have read his autobiography (which is a nice read and like all of Darwin's work, available for free online), Pell exposed his lack of understanding with regard to mankind’s evolutionary history with this startling exchange, which seemed to enliven Dawkins from his jetlag:
TONY JONES: Sorry, can I just bring you, in a sense, to the point of the question? Do you accept that humans evolved from apes?
GEORGE PELL: Yeah, probably. From Neanderthals, yes. Whether...
RICHARD DAWKINS: From Neanderthals?
GEORGE PELL: Probably.
RICHARD DAWKINS: Why from Neanderthals?
GEORGE PELL: Well, who else would you suggest?
RICHARD DAWKINS: Neanderthals were our cousins. We’re not descended from them and we’re both descended from...
GEORGE PELL: These are extant cousins? Where will I find a Neanderthal today if they're my cousins?
RICHARD DAWKINS: They’re not extant, they’re extinct.
GEORGE PELL: Exactly. That’s my point.
RICHARD DAWKINS: Your point is that because they're extinct they can't be our cousins?
GEORGE PELL: I really am not much fussed.
RICHARD DAWKINS: That’s very clear.
GEORGE PELL: Something in the evolutionary story seems to have come before humans. A lot of people say it’s the Neanderthal.
Sure perhaps it is a bit much to attack the Bishop for this mistake; after all he has no expertise in the matter whatsoever. But nevertheless, Pell should have just pushed it aside by saying, ‘oh well, I don’t really know much about mans evolutionary history’, rather than trying to argue about the relevance of this other species of human being extant, or cousins. He even goes on to state how Neanderthals weren’t the equivalent of humans because they didn’t draw on cave walls, even though there is new evidence that they in fact did do just that.
As the discussion continued about mans evolution and the implications of this toward those religions that believe man in unique and has a soul, I think there was further evidence showing Pell’s ignorance of modern evolutionary theory. For example he shows a misunderstanding of the continuous nature of species here:
“so we can't say exactly when there was a first human but we have to say if there are humans there must have been a first one”
There doesn’t have to be a first human at all, just because there is a human now. There is gradual change, so that no parent and offspring would be so dissimilar as to be labelled members of different species, yet these gradual changes would nevertheless compound over time to inevitably change the species (Dawkins in fact goes over this briefly, but adroitly, in a later segment, to which Pell inanely replies “if there is no first person we’re not humans”).
In talking about these ‘first people’ Pell made some headlines (virtual ones at least) in this article when he referred to Adam and Eve as mythology, and not fact.
When he started going over this mythology, Pell highlighted one of the things that I believe is a major difference between a theist’s mindset versus that of an atheist’s:
“[...] the key to the whole of universe, the really significant thing, are humans”
A very self centred view of the nature of existence I would think. What do you know, it is all about me after all. It’s like Phillip J Fry once said: “So I really am important? How I feel when I'm drunk is correct?“
“and, [...], it is a very sophisticated mythology to try to explain the evil and suffering in the world.”
I will just say quickly about the above that I don’t believe it is very sophisticated to assert that sins can be inherited, and that people are born, as Hitchens used to quote "created sick, commanded to be well”.

A while later when the talk again moves towards Richard’s expertise in science my favourite moment of the night appears. Take a look:
George Pell: You have to reason about the facts of science, ask whether you believe the suggestion that, you know, random selection is sufficient and also most evolutionary biologists today don't believe that.
RICHARD DAWKINS: Don't believe what?
GEORGE PELL: They don't believe in random so this crude fundamentalist version of random selection that you propose
RICHARD DAWKINS: I do not propose it and I strongly deny that evolution is random selection. Evolution is non-random selection. Non-random.
GEORGE PELL: So there is a purpose to it is there?
RICHARD DAWKINS: No.
GEORGE PELL: Could you explain what non-random means?
RICHARD DAWKINS: Yes, of course I could. It’s my life's work!
I love it, especially because so many religious apologists seem to forget that these scientists do have a whole lot of research behind what they are doing, and unlike a lifetime built up on theological ideas, they can explain them with due recourse to facts and observations. It just goes to show how much of religious disapproval of evolutionary theory is based on an unchanging image of the science as constructed by apologists, rather than an active understanding of the theory. That evolution is still considered by many who don’t understand it as a random process, is something which must infuriate Dawkins, and other evolutionary biologists, to no end.
Dawkins great strength is how he can explain something so well, in so few words. Take for example the explanation of evolution’s non-random nature which he gives to Pell:
“There is random genetic variation and non-random survival and non-random reproduction which is why, as the generations go by, animals get better at doing what they do. That is quintessentially non-random.”
Next, an atheist asks a question about what will happen when he [the atheist] dies and we get a long response from Pell (prodded by Tony of course) which goes into some of the intricacies of the Christian mythology, but again I like the concise and rational nature of Dawkins response:
“Well, the answer to the question of what’s going to happen when we die depends on whether we're buried, cremated or give our bodies to science.”
Bam, done.
As the discussion delved into more Christian mythology, and Pell defended such things as bodily resurrection and transubstantiation, he again hinted toward the mortal origins of Christianity upon acknowledging the adoption of yet more Greek culture and thinking into the Christian ethos:
“I understand it [edit: transubstantiation], according to a system of metaphysics. It was spelled out by the Greeks before Christ came, which we have adopted [......]”
Though I suppose it could be said that the referrals back to a previous culture don’t just show the human origins of religion, but rather that it may reflect a universal truth not quite grasped correctly by the Greeks. But honestly; which is the simpler explanation?
Dawkins calls out another tricky tactic of the religious apologist when he continually tries to get Pell to explain how some of the language he is using actually applies to real world usage, and our way of employing the English language. When Pell tries to explain how the wafer does become the body of Christ via transubstantiation, but remains as a wafer for all intents and purposes, Dawkins retorts:
“I mean I use - English is my native language. The wafer does not become the body of anybody in the English language.”
However as Pell had previously said:
“I believe it because I believe the man who told us that was also the son of God. He says, “This is my body. This is my blood,” and I’d much prefer to listen to him and take his word than yours.”
It is clear that a rational discussion about language and how it should be employed (with common definitions and syntax) is useless against someone who defines words by divine fiat, not in any proper linguistic fashion.

Seeing that this discussion was going nowhere, Tony interjected with a new, and refreshingly brief, question from the audience:
“Is it okay to tell a child that God doesn't exist? ”
This is one I have thought about a lot as my son is growing up in a culture that frequently talks of God, gods and heaven, albeit generally in a metaphorical or profane (“God damn it!”) sense. Dawkins does well, saying that he would prefer for her to figure it out based on the evidence [he has a great open letter to his daughter, hence the ‘her’, that can be found over here]. After all, he is an agnostic atheist, and would not be willing to tell his child that a god doesn’t exist with 100% certainty anyhow.
Then when Pell was starting his response to this question, he unintentionally got the biggest laugh of the night with this statement, which were it not coming from a member of the catholic church, would barely have registered a stifled giggle:
“I remember when I was in England we were preparing some young English boys”
I smell a meme on the way!
Thank you Sam Dekok for being so on the ball making this
Some people have said that it was a bit crass of Dawkins to laugh when the audience took amusement from Pell reminiscing about ‘preparing’ some English boys, but I think that given the Catholic Church’s history in this regard, it is hardly an unwarranted jest.
Then when the laughter dies down, and he finally gets it out, Pell’s self styled ‘simple’ answer to the question of whether kids should be told they are going to hell is this:
"Hitler. You think Hitler might be in hell? Started the Second World War, caused the death of 50 million or would you prefer a system where Hitler got away with it for free?"
Would you prefer it? As if preference has a bearing upon reality. I am sure the kid would prefer a universe where suffering such as the like committed by Hitler, was simply not possible.
This personal drive for justice to be handed out even after the grave is brought home when Jones presses him further (as he is sooooo good at doing):
TONY JONES: What about a system where he was obliterated and didn't exist anymore?
GEORGE PELL: Well, he would have got away with too much, as far as I am concerned.
But Pell doesn’t give up, he is determined to show that simply wanting the universe to be a preferable and just one is somehow an argument for it actually being such a universe.
“But I believe on behalf of the innocent victims in history that the scales of justice should work out. And if they don't, life is radically unjust, the law of the jungle prevails.”
‘On behalf of the innocent victims’, implicitly suggesting that those atheists who don’t believe there is justice in the universe from some divine after death source, are somehow not on the side of the victims.
True, a world where the Hitler’s and Mengele’s can simply die and escape justice may not be a just world at all. However saying this doesn’t really add weight to the argument to that your idea of what the world could be like is nicer than an alternative, and therefore that it must be true.
I believe that the world is essentially an indifferent place, which is why I don’t think that justice is something to be doled out from beyond the grave, but rather that justice, like ethics and happiness; is an entirely human affair.
Dawkins likewise is having none of this, and simply responds to the question of which reality is more preferential with this little nugget of rationality:
“I’m more interested, however, in what’s true than in what I would like to be true.”
Any talk of suffering or justice in regard to a religious worldview is bound to ask the question of why an omnipotent god would allow such things to happen. Pell offers up the same ‘free will’ argument so often employed, yet very rarely explained:
“That’s a very good question but if God is going to allow us to be good he’s got to give us freedom.”
Freedom perhaps, but ability; no. We can easily be given the freedom to do things, without making every possible action available to be done. For example, we have the ability to kill, and maim; but is this physical reality required in order for our will to be truly free? I don’t think so. We could have bodies incapable of feeling pain, or being killed, whilst retaining our free will, so this reality still needs to be accounted for.
As the night quickly came to an end, I think Pell was beginning to lose interest in the whole affair. He had shot himself in the foot a few times along the way, and then added this nice snafu to the mix when talking about secondary causes in regard to how a perfect god would design a just universe:
GEORGE PELL: It is interesting through these secondary causes probably no people in history have been punished the way the Germans were. It is a terrible mystery.
TONY JONES: There would be a very strong argument saying that the Jews of Europe suffered worse than the Germans.
George Pell, you have been Tony Jones’d.
As if that weren’t enough to highlight Pell’s mounting disinterest in his side of the exchange, his final words for the night consisted of this exchange:
GEORGE PELL: [...] my life would be much simpler and much easier if I didn't have to go to bat for a number of Christian principles.
TONY JONES: Have you ever regretted that you do?
GEORGE PELL: Sometimes I wonder.
TONY JONES: Seriously?
GEORGE PELL: No. No. No. 
Ah yes, if only it was the good old days, when Catholic Cardinals didn’t have to try and explain themselves to the people, and could just force through their will with divine right.

Anyhow, that is my commentary on the Dawkins v Pell episode of Q and A. I hope it was enjoyable.

Oh, and one quick last minute mention of another meme created after George Pell replied to a question about the existence of gays within his god's master plan in this exchange:
TONY JONES: Can I just interpose a quick question on this. We are running out of time. I mean do you believe that homosexuality, since it’s not a question of choice, is part of God's natural order? GEORGE PELL: Creation is messy. I think it’s the oriental carpet makers always leave a little flaw in their carpet because only God is perfect. 
I love the internet

On Moon Landing Evidence and the Dangers of Conspiracy Theories

2010 marked the year of extensive lunar mapping thanks to the launch of the Lunar Reconnaissance Orbiter, and as a result scientists and regular science loving people were quick to come out and use some of this new lunar photography to thwart an old foe, stuck firmly in the popular imagination: the Moon Landing Hoax conspiracy theory.
Back in September of last year images of the Apollo moon landing sites were released, which showed not only the remains left behind from the lunar landers, but also the tracks left by the astronauts themselves (as the moon has no atmosphere to disturb them after 40 odd years).

Then again last week another announcement was made which had one article boasting “refute this hoax lovers; more proof men totally walked on the moon”. This was in response to more images made public which show moonwalkers Pete Conrad and Alan Bean’s tracks from their sojourn to the Surveyor 3 probe while on the moon as a part of the Apollo 12 mission.
Now I love science as much as the next guy, and yes if I meet someone who entertains the idea of a moon landing hoax, I am quick to get an argument going (if only a friendly one). But it seems a bit odd to be touting this new evidence as being in any way convincing to those in the conspiracy theory camp.
After all, they are willing to dismiss photos apparently taken on the moon back in the 60’s-70’s; so why should we feel confident in debunking their theories with photographs taken remotely? Not to mention the more important fact that these new images were produced in the modern age of Photoshop and computer generated imagery. If anything, the release of these images is something that would have been long expected by any forward thinking hoax claimer. Of course NASA and the shadowy government conspiracy (which must be staffed with a lot of very old men these days) would have the ability to fake photos from satellite; after all they even placed laser reflectors on the moon to support their lie.
I wouldn’t even be surprised if when future people return to the moon, and the Chinese explorers there tour the remains of a once mighty America’s space efforts, that there would be people who still maintained that the landing was a fake, and any subsequent evidence was a party to this.
This is always going to be the case, as with most conspiracy theories there are pervasive elements at work that undermine our mental faculties. They are driven by wants and desires; generally of the kind where we don’t want something to be true. We don’t want to believe that an influential person like JFK, who seemingly had such a steadfast place in history set out before him, could be so easily taken from the world by the actions of a lone gunman. So we push our reasoning slightly aside, and delve into the conspiracy theory box to pull out something that agrees with how we want the world to be.
Doyle’s Sherlock Holmes once said “It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts”, which seems to capture the general idea, except that in this case the conspiracy theorist twists the facts to their theories when the alternate theories seem too impalpable.
This abandonment of rational thinking is a dangerous thing, as once you get rid of the tenets of evidence and logical thinking, you will find self referential confirmation and verification all too easily.

It reminds me of that other great conspiracy theory. The one that states that after we die we don’t actually cease to exist, but rather there is some obscure secondary existence awaiting us. Something that is hidden from the world as we know it, but nonetheless must be out there, because if it wasn’t, then we would have to live up to uncomfortable realities.
And the best part about conspiracy theories (and yes, religions too), is that it takes relatively little effort on our behalf in order to ascribe to them, and reap the mental benefits of believing our world is just that little bit better.
It is easy to assert that man didn’t walk on the moon, as you don’t have to give up anything, except perhaps the respect of a few more discerning people.
The problem with conspiracy theories, as with religion, is that you can evoke your powerful external force in order to explain away any objections to the theory. In the Moon Hoax example the external force is some form of government body who are either working to keep the lie undercover, or else have simply succeeded in their goal of fooling the world, and are now inactive.
In the case of most modern religions, the external force is much more potent, as any god can generally be said to have controls over reality, and thus any contrary evidence to the god’s theory can be explained away through magic. This is akin to how people used to claim (and some still do today) that the fossil record is a work of the devil, put there to fool man. The external powerful force at work.
Clearly the work of the devil
Once you start entering in these agents with seemingly limitless abilities, you can work your way around almost any rational argument, or contrary evidence.
This is the crux of the Flying Spaghetti Monster’s theology, where any experiment or evidence which appears contradictory to the word of the Pastafarians only appears so due to the diligent manipulations of ‘his noodly appendage’.
So in closing, though I like these new images being produced from the Lunar Reconnaissance Orbiter, I don’t think it is wise to use this evidence in an argument against conspiracy theorists. Their bag of magic tricks can explain away anything that could be used as proof, especially now that the thing we are talking about is set firmly in the past, and beyond direct investigation.
Rant complete.

P.b. (post bloggedum) 
I also note that Russia has announced plans to get a cosmonaut to the moon by 2030. I guess second place in the space race is still quite an achievement, even if it would mark sixty years since the yanks beat them to it.
Then again, it might get crowded up there, what with the Chinese and Indians hoping to beat the Ruskies to it in 2025 and 2020 respectively.

2012: A good film but a shit doomsday

Yesterday, my wife and I rewatched the 2009 disaster film 2012.
Witty caption pending
Though generally this film was lambasted by critics, I cant help but take the line of US film critic Roger Ebert who at least seems to get these kinds of films, without trying to pretend that they are an exemplary example of what all films should be (which I feel is a problem with many critics out there).
Check out his review here, or just read this quote:
"This is fun. "2012" delivers what it promises, and since no sentient being will buy a ticket expecting anything else, it will be, for its audiences, one of the most satisfactory films of the year. It even has real actors in it. Like all the best disaster movies, it's funniest at its most hysterical. You think you've seen end-of-the-world movies? This one ends the world, stomps on it, grinds it up and spits it out."
Like the man suggests, unless you missed out on Independence Day, Godzilla and The Day After Tomorrow, you should know what a Rolland Emmerich film has in store for you. Leave your brain at the door, and just enjoy yourself. These films aren't looking for realism, they are just looking to entertain; and at the end of the day there isn't anything wrong with that. Not every film needs to be a masterpiece; not every character needs an arc.
I think of films like this as the equivalent of MacDonalds, or one of those microwavable pizzas; its not a great meal, and you wouldn't want to subsist on this for the rest of your life. But every now and then you just want a quick, easy, and tasty meal.
Sometimes its best to just think of these films as set in an alternate reality, where things are different, people always beat the odds, and so on. That way at least you can let a lot of things slide and just enjoy the ride (hey that rhymes).
That all being said, I still cant help but cringe at a few points in the film.
Like the opening montage of shots set in space, showing the alignment of the planets. Now I can look past the whole 'alignment of the planets causing catastrophic problems for earth' theory, but the fact that the solar systems planets are either shown as being much more massive, or else much close to each other, than they effectively are ruins the moment for me (especially when the films plot relies so little on this fact).
Then, right near the start of the film again, we have an astrophysicist talking about neutrinos, and studyting them in a subeterranean laboratory. This had its promise, because I know this is exactly what they do. But then we hear some nice 'sciency' buzz words, as we are informed that these nuclear particles are behaving strangely, and are interacting with matter in a way that they usually dont. The astrophysicists explanation: they are mutating.
Nuclear particles, mutating.
Why not just say they are degrading into other particles, or transforming, or something like that. Anything but mutating, a term which should sit firmly in biology, and not physics.
As you can see, this evidence clearly shows these neutrinos are going through puberty.
I could go on all day about the scientific inaccuracies in the film, but I don't want to give the impression that all of this bothers me too much. As I said, brains at the door fun. Its just that these little things could easily have been avoided or changed without altering the film pretty much at all. I can let the objections to tsunamis making waves in the middle of the ocean big enough to knock over ships, and the improbability of a limousine being able to drive through a building as it collapses, fly out the window; because this is the entertaining stuff I wanted from this kind of movie, and it wouldnt be the same without it. But the  astrophysicist could have just said something more sensible, and the planets aligning could have been shown to look more like stars, than actual planets in the near distance.
On to the next cringe worthy moment, and this time it was due to technical buzz words, as opposed to scientific ones.
In every scene that he is in, much like his role in Zombieland (also released in 2009); Woody Harrelson steals the show. This was a great year for fans of Woody (that doesnt sound right), one of which I happen to be ever since growing up in the 90's when he taught me that in fact white men can jump.
Two prime examples of how not to wear a cap so as to keep the sun out of your eyes
Anyhow, childhood references aside, Woody Harrelson plays Charlie Frost, a deranged conspiracy theorist who turns out to be pretty much right about everything in the end. The thing that bugs me here is only a minor point, but it irked me on re-watching nevertheless.
When Charlie is trying to inform the protagonist of the worlds impending doom, he tells him to 'download my blog', to which John Cusack clicks a few buttons on a laptop, and ends up watching a nice little flash animation outlining the films basic disaster plot.
'Download my blog'? Is that really how we talk about it? Perhaps I am being picky, perhaps I am wrong, or perhaps this was just meant to be the crazy characters quirky way of talking; yet I cant help but be annoyed that he didnt at least say 'look at my blog', or 'watch this video', or something that makes a bit more sense. It really just seems like someone who isnt savvy with todays technology trying to write some dialogue. [p.s. I know Woddy's character to be computer literate as he made the animations himself].
"Stand back; I'm about to do some internets"
My last gripe with this movie involves the President of the United States character played by Danny Glover.
After he gallantly decides to remain with the American public as their nation comes to an end, rather than flee with the other main notable actors to the ships in China, he delivers his stirring last address, and utters this little line:
"We are a nation of many religions, but I believe these words reflect the spirit of all of our faiths: The Lord is my shepherd, I shall..." [dramatic cut-off]
This is what he was quoting, Psalm 23 from the Bible. Tell me, how does that reflect the spirit of all faiths? Also, what about the 30 million atheists in the United States? Do they not warrant a mention here? I know past American presidents have shown a less than accommodating stance toward us unbelievers ("I don't know that atheists should be considered as citizens, nor should they be considered patriots. This is one nation under God" - George Bush Snr.), but at least Obama's inaugural speech mentioned them on equal footing with other citizens ("We are a nation of Christians and Muslims, Jews and Hindus – and non-believers." - Obama).
I mean it isnt really a big deal, but like everything else in this rant; it bugs me all the same. How does such a quote reflect the spirit of Buddhism for instance? They arent really fans of the whole 'Lord is our shepherd' thing. Nor are Hindus, or Sikhs, or to a degree Muslims. And what about the poor Scientologists?
"I'm too old for this comparative religion shit" President Murtaugh
Something I also noticed on the news the other day is this report on the suns solar activity, which is at its highest peak since 2005. Spooky huh? After all, it is 2012, the year the Mayans famously predicted the end of the world.
Except for it isn't. The Mayan long count calendar ends in December 2012, but then again so does the calendar on my desk at work. When that time comes, I wont be cowering with the ones I love, converting into a dodgy Christian and appealing to my shepherd to look after me; I'll just order another calendar.
Note that this is also what happens with the true Mayan calendar. 2012 doesn't signal the end of the world, but rather just the start of a new long count calendar.
So like most end of the world scares, this too is quickly dispersed with a healthy dose of logic. NASA has a great article debunking the whole 2012 over here.


Rant complete.

Bits of the World Trade Center live on


I am a bit late with my obligatory September 11th post, but then again I was around a year late in starting this blog, so I figure I can still get this post out there.
Rather than focusing on the obvious stuff: on the regret, and the sadness, and the reflections of how this day ‘changed everything’; or the resulting wars, and other terrorist attacks; the now seldom mentioned War on Terror, or the ultimate demise of the mastermind of that horrible act a decade ago. Rather than follow suit with a similar post, I am instead focusing on some of the more interesting results of that dark day in 2001.

True to the enterprising spirit that made the United States the capitalist juggernaut of the 20th century (I'm not extending this into the current century because I’m not that optimistic), the wreckage of the Twin Towers has been utilised in two interesting ventures.
The first is perhaps the most American of the two; the building of a warship, the aptly named USS New York. Soon to be followed by two sister ships named after the other crash sites from the terrorist attacks (the USS Arlington and the USS Somerset), the New York was created partially with steel from the collapsed towers.
Ooh-rah!
I guess it is fitting that a relic of the greatest attack on the United States homeland become a part of the navy designed to protect it, but I cant help find it amusing that of all things in Americas arsenal, a warship is probably the last thing that would be useful in combating the threat of terrorists; especially those who hide out inland, be it in caves, or swanky Abbottabad compounds.
The scrap steel utilised from the towers was melted down and now forms part of the ship’s bow, and though it only comprises less that 0.1% of the ships total mass, it was more of a symbolic gesture to go along with the ships name.
There is something true to that war hungry oriented view of the United States which goes along well with this usage of World Trade Centre scrap metal. Even if you don’t look at the militaristic nature of the U.S as a bad thing (it was a thing of pride for many people in watching the forces of ‘freedom’ rise up in opposition to the growing communist war machine many years ago), it is still somewhat fitting that what was once a symbol of American power is now transformed into another, more literal, form of power projection.
However we don’t only associate Americans power and influence with the tip of their metaphorical sword, but also with their technological and scientific reach. That’s why I was again both surprised, but also quite accepting to find out this week that there are parts of the World Trade Centre rubble now on Mars, exploring the red planet.
It seems that one of the contractors working for NASA on their latest Mars Exploration programme was able to incorporate some of the rubble from the towers in their design.
Honeybee Robotics was tasked with the creation of the drilling mechanisms for the Spirit and Opportunity rovers due for launching to the forth rock from the sun in the year 2004. Their offices are located in lower Manhattan, and as such the events of those days really hit home for them, and they decided to honour the spirits of those lost by including some parts from the collapsed towers in the rovers.
They used recovered aluminium to create the cable shield for the rock abrasions tools each of the rovers use to analyse the martial soils. You can see a picture of one of them, stereotypically adorned with the emblem of the flag of the United States, in the image below.
