Some Views of "A Skeptical Look at Atheism"


As many of you are aware we had Professor Andy McIntosh come and talk to us at Birmingham Skeptics in the Pub on “A Skeptical Look at Atheism”. Andy is an Emeritus Professor in Physics, specialising in thermodynamics and is also a Young Earth Creationist on the speakers list for Answers in Genesis. His talk was, to say the least, different to the usual that we have at Skeptics in the Pub. The Q and A session wasn’t nearly enough to address everybody’s questions and comments and so we thought we would crowd-source a few for interest. I was going to summarise and edit the views sent in but I don’t think I can do that fairly and keep all the excellent points that the contributors made. I apologise therefore for this mammoth post but please stick with it as there are some great points made and some interesting news at the end.

Our first review came from Andy McIntosh himself via none other than Ken Ham of Answers in Genesis! Surely we’re the first Skeptics in the Pub group to get a review by that particular person. Imagine if we could get him over to talk!

You can read Andy’s
review here, he seems to have enjoyed his opportunity of preaching to the largely unconverted and was happy that his combination of scientific and philosophical argument was listened to and may have planted seeds of faith.

Lets contrast that with this excellent review sent in by Mil:

OK, before I start I should mention that I didn't stop for the second, Q&A part. I needed to catch a train - I don't live in Birmingham, because, given the choice, you don't live in Birmingham.

The thing about Professor McIntosh's talk - and I honestly don't say this to mock - is that it felt like watching someone go incrementally insane. Putting aside his opener about the feather (presumably included because he could not resist catching Richard Dawkins saying that he, Dawkins, had 'faith' in something), the first half of the lecture was informative and within striking distance of well-reasoned.  Whether one finds McIntosh's conclusions sound and persuasive or not, it did address the matter of the creationist invocation of the Second Law of Thermodynamics as a bar to evolution. The typical response to a creationist saying entropy must increase is to simply reply by finishing the sentence - 'in a closed (or isolated) system'. And that's generally the end of it: the creationist goes off to find another half of a sentence to use, and you can sit back and have a biscuit while you wait. Professor McIntosh explained why such a brisk dismissal of his position mischaracterised it. He, of course, is aware of what the law states and that the Earth isn't an isolated system; his argument rests, rather, on energy that's 'useable' by what he refers to as 'machines'. This is all fair enough as a clarification of a subtler argument, drawing on established scientific principles and so on.

That was the starting point. The finish was that Jesus is our Lord and the eye-witness accounts in the Bible prove it.

It really was like watching someone descend into delusion before your eyes. My internal response to the things he was saying followed this sort of path: "OK... Ahhh... Um... Eh...? What...? *What*...? WHAT...? ARGGGHHH!" At the beginning what he's saying at least appears plausibly worth addressing; in the middle he's, for example, telling us that atheists have no response to the arguments CS Lewis puts forward in 'Miracles' (so he's now reached what one might - generously - call 'shaky ground'); by the end it's the kind of stuff that wouldn't fly in a Year 10 classroom debate - I expected at any moment to hear the words 'Pascal's Wager', 'There are more of us than you', and 'Hitler'.

Professor McIntosh seems like a decent chap, he has genuinely-held beliefs, he's laudably keen to engage with those of differing views, and he's no doubt orders of magnitude a better mathematician than I am. Yet as the talk went on his reasoning simply fell to bits in breath-taking fashion. The room listened, and everyone really, really wanted to be polite, but towards the end there was a distinct rippling noise from the crowd - no one was actually interrupting, it was rather the sound of two hundred people all furiously trying to bite their tongues.

It was great to have a speaker who wasn't preaching to the choir, though. I'm very glad the Birmingham SitP invited Professor McIntosh, and I'm glad I went to listen. I have, however, not changed my position on the place of 'Intelligent Design' in school science lessons.”

It might come as a surprise to some but not all the skeptic regulars are atheists. One of our greatest supporters is the wonderful Abby who sent us this review from a Christian Skeptic perspective:

“As Christians neither me nor the friends who joined me on Weds, are literal creationists, and I have heard that nearly all mainstream Christians within the sciences refute creationism too (one even wrote of being cured of it) so I had my doubts as to how we’d find the evening, but that particular argument wasn’t really dwelled on during the evening. As I’m not highly qualified in science, here’s a more technical response from a couple of my friends who came along from church,  one’s a physics  teacher, and one’s a biologist, currently doing a PhD in immunology.

Both friends said that there was nothing contained within the evening that they hadn’t already thought about themselves. However, they said the science did seem to have a point:

The physics teacher says that indeed, "Thermodynamics says that entropy will always increase (everything tends to a state of maximum disorder) - which is seen in nature (physics at least).

The biologist tells me; in agreement with a sceptical counter-argument I heard following the talk, that entropy actually increases the amount of information. However, she said we have to ask ourselves what kind information there is in random noise, something structured / self-producing... It’s all very well it being 'information' but it’s got to be the right kind and that’s where the entropy argument comes in as it also refers to energy. To create the structures of life, you have to have energy.

However, both people, like myself, thought that the talk could have been presented in a much more clear and engaging way, making the relevance of what he was pointing out a little more self-evident (without needing a resident physicist and biologist on hand, guilty as charged). The biologist said “I was a little annoyed he didn't delve deeper. He was almost a little patronising constantly saying that he 'wouldn't go into that”. We all said we know this is difficult though, as by its very nature it’s specialist stuff, and he didn’t always have the time to expand.”

From our comments section Tituslivius gave us this succinct and pointed view of the night:

“I was expecting something a bit more heavyweight than this. I was mystified by one of the arguments presented (actually an ad-hominem attack) concerning Richard Dawkins' response to a question about the structure of a feather. We were only given half a sentence, without context, of what Dawkins was supposed to have said, and then invited to draw the inference that his entire stance was thereby compromised. Nothing was proved or even demonstrated by it. I would be interested to hear from people who stayed for the question session”



Also from the comments, Gurbie0 addressed some of the scientific and moral arguments presented by Professor McIntosh:


“His comment on how, according to an atheist view on the human mind (in that atheists don't believe in a separate 'soul' and our thoughts are just 'chemical reactions'), it would be possible to tell what someone was going to think using a large enough supercomputer was very interesting. I don't know enough about brain mapping or supercomputers to know whether this would be possible, but I can see how hypothetically it could be. However, even if it were possible I don't see what McIntosh's point was. He seemed to think that just because he found the idea disturbing that the idea was therefore flawed. He used a similar argument when talking about another aspect of the human mind, where he said that seeing humanity as 'chemical reactions' seemed 'miserable'. I'm sure some people do find the idea miserable, but that does not mean it's not true. Just because you don't like an idea does not decrease its validity.

He spoke about 'information', the point of which (as far as I understood it) was that a 'code' (such as that carried in DNA) could not exist unless a message existed prior to it. Then the message could be put into code, and then interpreted somewhere else. Of course if this were true then DNA could not have evolved or appeared naturally, as it would need a message provided by something else. McIntosh suggested that this initial message must have been provided by God. This idea can be debunked using a simple analogy: I, or a computer, could write down 20 entirely random letters, without any 'message' written into it or any code devised. This could then be given to someone, and that person could devise a random letter substitution system in order to 'decode' my sequence of letters (e.g. a=t, b=e, k=d). This, almost certainly, would just give a sequence of letters just as random as the original code. However, if the person did this 10 million times, devising a new decoding system every time, then one of those time would almost certainly result in a sentence with meaning, and 'information', even though the was no 'information' in the original code. That is how DNA could arise, with natural selection 'picking out' the meaningful sequences from the nonsense.

He seemed to think that atheism gave no explanation for 'morality' or altruism. Of course these things are easily explained by evolution, but since he had already decided the science proved evolution impossible he must not have considered this. He also assumed that atheists agreed with the idea that there is an absolute morality, which of course many do not, and many have very different ideas on the meaning of the term 'morality'.”

Our previous contributor Mil posted this response to Gurbie0’s comments:

“... your mention of McIntosh saying one could “tell what someone was going to think [in fact, be able to tell *everything*, not only thoughts, in advance] using a large enough supercomputer.” What he was doing there was simply giving a microprocessor face to ‘Laplace’s Demon’. The notion can be criticized on the basis of it being, mathematically, impossible for any such ‘all knowing predictive thing’ to exist. Which, IMHO, misses the point very badly – it’s like saying that ‘infinity’ is a false concept because you can’t build infinity as there’d be nowhere to put it. The other major criticism of it is that causal determinism is mugged by quantum randomness. Now, some argue that so called quantum randomness isn’t, or has not been demonstrated (and could never be demonstrated) to be truly random - Galen Strawson, for example. That, IMHO, again, misses the point too, though less badly. What’s at issue here is freewill, and introducing randomness doesn’t save freewill – chance is not choice. So, it doesn’t matter very much that you (and I) aren’t experts on brain mapping and supercomputers. You’re gleamingly correct: the real rubbing nub of the issue is McIntosh’s focus not on whether something is correct or not, but on whether it’s preferable. He might as well say, “Reality worries me, so I’m going to believe in something else instead.” Which – I’m sure you’re ahead of me here – could explain his position on quite a few other things too.”


Personally I wondered how somebody so sure about their ultimate answer (God) could look at any science totally objectively. It seemed to me that the science of the talk quickly gave way to his faith and that the latter was the stronger of the two. He obviously has a better grasp of physics than I do but to establish the kind of belief that he has you would have to discredit or ignore the consensus of scientists from multiple disciplines including geology, biology, astronomy and palaeontology to name but a few.

This topic is far from over and you don’t need to let me have this final word. You can continue to contribute to the discussion, we welcome any comments that you would like to make. For those of you that couldn’t make the event, or aren’t quite sure you did actually hear what you thought you heard, we’ve produced a DVD of the entire talk which should be available at our February meeting. It has a snazzy cover designed by Paul Bryant (@thebigyeti), photos by Simon Brettell (@simonbrettell) and video editing by Chris Richardson (@christheneck). You can watch the talk and the questions unedited, free to throw peanuts or shout at the screen from the comfort of your arm chair Let us know if you want a copy and we'll try to bring enough along. The cost will be £3 if you buy direct in person or with added cost for postage and packing if you live elsewhere. You can email us at skepticaldvds (at) gmail (dot) com or via our contact page.

We’re not uploading the talk because the speaker doesn’t want us to and because we don’t want to. We appreciate the work that our speakers put into their talks so if we do video them we’d rather not dilute their future impact by uploading, (although if it was a homeopath perhaps diluting would make it more effective). If you’re interested in buying one of the videos any profit made will, as always, be put back into Birmingham Skeptics in the Pub so that we can continue inviting great speakers and plan for even bigger and better future events.

Why Nothing Matters


By Ronald Green

Why should nothing matter? If anything matters, why should nothing matter? And yet it does, for there isn’t anything, it seems, that nothing does not touch, or anything that does not touch nothing. History, philosophy, religion, science, art, literature, music – all look towards nothing at some point, stimulating questions that would otherwise not be asked.

What is this nothing, that we can’t actually see, touch or feel? Is it absolute? Is it relative to everything else? If we are able to think about it, write and read about it, is it something, and if so wouldn’t it then not be nothing?

This is precisely the mystery of nothing – that the more we think about it, the more there is to it.

The struggle to understand the concept of absolute emptiness, the absence of everything, has been going on for some two thousand years, for at least as long as there have been written records of what people thought is important. Those who have made it their business to think have been puzzling at "nothing", wondering what it was, whether it was anything at all, whether it existed, in fact, and if it did, how it affected things around it.

Jon Ronson - Time to get Organised

These have been exciting times for us here at Birmingham Skeptics.  We’ve had some brilliant talks over the last few months, word is getting around the midlands and as a result our talks have been getting more and more popular.  Those who were at Ash Pryce’s excellent ‘How to be a Psychic Conman’ show will have noticed how popular it’s become.

On top of this, we’ve got the amazing Jon Ronson doing his talk ‘The Psychopath Test’ for us next week (13th July) at The Victoria.  We’re really looking forward to it, and, looking at the numbers that have responded on Facebook, lots of other people from around the area are too.

As a result of this, we’ve decided that we need to be a little more organised

SCEPTICISM: THE HUMAN ELEMENT

A blog post by Dean Burnett



In my school, we didn’t get that many people trying to encourage us to get interested in science. As a poorly funded, over-populated state-school in a largely ignored area of Wales, we were treated to regular performances by groups trying to get us into Christianity, who apparently subscribe to the same logic as army recruitment officers, worryingly enough. Many a time was the entire school made to sit for hours on the hard floor of the assembly hall while a group of jovial individuals, with expressions that always seemed just the wrong side of psychotic, performed skits, sketches and songs with the intention of convincing us that loving God and Jesus was ‘awesome’. To my knowledge they failed conclusively to leave us with anything beyond the unfortunate yet sometimes prescient association between fundamental Christians and soreness of the posterior.


I had problems with many of the things they said/did even at the tender age of 11/12. One group mimed a sketch where one man was stuck to a chair and his friend was attempting to free him. After several failed efforts, the would-be rescuer knelt down and prayed, and lo, his friend was freed from his sticky four legged prison. The moral was something like ‘in times of crisis, prayer can be of great service’ (as a solvent, apparently).


Another group tried to wow us with a flashy light-show and multi-media presentation, completely missing the irony of using the latest high-tech devices to engender support for a religion which isn’t really keen on the whole ‘progress’ thing. They tried to impress us with facts about the bible, including the pearler “if all the pages in the bible were laid out end-to-end, they would go round the world 1 and a half times!” Even as a child, I reasoned that if this were true it surely says a lot more about the printing press than it does about the bible itself? It isn’t true, by the way, unless they were referring to the deluxe version of the bible, including the books by the 23 missing apostles and printed for visually impaired Ents.


But one thing I will say for these poor deluded people is that they did at least attempt to engage with us on a personal level. Granted, these efforts usually resulted in their audience applying intense scrutiny to the ceiling or their own shoes as what was happening on the stage was so hideously patronising and cringeworthy. But it is my personal belief that this effort to engage on a personal level is something science and scepticism is missing, and attempts should be made to rectify this.


A controversial theory, perhaps, and I fully expect many to disagree with me, but I have reasons for my position. I get my cynical side from my dad, who had a very refreshing approach to scepticism. He isn’t a scientist or anything like that, he was the landlord of the pub I grew up in. One of his hobbies was tormenting the Jehovah’s witnesses who regularly came in to ‘save’ him. If they didn’t leave in tears, he considered himself a failure. And to my knowledge, he’s the only one in the local community that our alcoholic vicar actively wished death upon, apparently as a result of the night that my father dangled him off a bridge by the ankles until he admitted there was no God.


So my sceptical role-model was a bit more ‘hands on’ than most. My own experience is also worth taking into account. I’ve just completed my PhD in Neuroscience after 5 years. For a similar length of time, I’ve been a stand-up comedian, so I have a lot of experience at trying to reach people and gain their approval on a personal level. As a result, I believe the personal element could prove integral to the promotion of rationalism and scepticism.


It’s completely understandable why science tends to avoid the personal element; it’s not very rational, non-quantifiable and differs wildly between individuals. But it is infuriating to me how so many of sciences detractors are free to use the personal, emotional and (depressingly often) hysterical approach in their insane attacks, whereas the ambassadors of science and rationality, bound by the noble but self imposed code of conduct, usually listen to the hysterical diatribe and then point to the evidence and data which supports their position.


Trouble is, although it’s the only acceptable method of debate between scientists, pointing out the evidence and logic is not going to be effective on people who have already decided to disregard it. When someone passionately rants about out their insane theory regarding homeopathy or chiropractic or the healing properties of daily colonic infusions of horseradish broth (give it time), spending hours describing the precise scientific details and flaws in their arguments will be less effective than the four words ‘You are an idiot!’ (And I speak from experience). It won’t convince them of your argument, but it will diminish them and undermine their position; by addressing them in their terms, it could eventually come down to who has the most evidence for their argument. And then sceptics are landed.


Egos are both powerful and fragile things. They prevent people from accepting that, just perhaps, they DON’T have access to some wondrous healing technique that is suppressed by the man. Perhaps most pharmaceutical companies couldn’t care less about alternative medicines. Perhaps their childs disorder is the result of incredibly bad luck and nothing more sinister. Ego must be a contributing factor, as amid all the accusations of conspiracies and closed mindedness, the one accusation that is rarely levelled at those who don’t agree with pseudoscientific claims is that, perhaps, they’re too smart to do agree? Funny that.


But it’s the ego that can be the weak spot. When a heckler has a go at a comedian, it’s their ego which tells them they’re funny enough and have enough support from the audience to do so. But if the comedian responds with a cutting and humiliating comeback, it’s the damage to the ego which shuts them up. Maybe this can work with the pseudoscientists too? Witness the popularity of Tim Minchin’s ‘Storm’ video, or the smash success of Robin Inces gigs which provide celebrations of rationality and reason through the medium of humour and performance. Even my own blog posts poking fun at sciences enemies have proven alarmingly popular, despite my amateurish attempts at writing and humour. By appealing to the personal element rather than just letting data and evidence speak for itself (as it usually speaks to people in a dialect they can’t understand), or even worse, letting the media insert the personal perspective without having any clue as to whether it’s correct or not, Science and rationalism can seem far more approachable and acceptable than it does to many at present.


I’m not saying Science/Scepticism should be offensive and rude, but it’s surely fine to defend itself in the same manner in which it is defamed? And I’d actively encourage this trend in treating the critics with the same scorn that they seem so keen on dishing out. And by showing scientists and sceptics as people with lives and feelings and opinions of their own, it could dispel the negative stereotypes that abound. It’s not scientific or rational or even that logical, but people aren’t, and people are who we’re trying to educate and enlighten.


I remember once when I was at a gig, and a fellow act asked what I did for a living (correctly assuming that I was nowhere near good enough to be paid for doing comedy). I told him, and he pulled an angry face then asked if I did any animal experimentation. I told him that sometimes I do, and he angrily responded by saying;



“You’d better not do any of that round me, I’m a vegetarian”


I didn’t know where to begin with that. The implication that I carry rats around in my pocket on the off chance I’d have a spare 5 minutes in which to conduct research (e.g. waiting for a bus), the implication that I was going to eat it, or the suggestion that I would deliberately ‘do research’ around him in a vindictive manner? In the end, I settled on those four words, ‘you are an idiot!’
Then I dangled him from a bridge until he said sorry. Unlucky for him, I don’t have the upper body strength of my dad.



Dean Burnett has recently acquired a PhD in Behavioural Neuroscience. He has also been a stand-up comedian for 5 years. This bizarre combination of skills has gained him much interest and media attention, but has thus far failed to find him stable employment. As such he spends much of his time writing snarky skeptical articles for anyone who'll read them. Make sure you read his blog Science Digestive.

Science in the News

A Blog Entry by Tulpesh Patel

The relationship between science and the media is a complicated one. The former is concerned with communicating evidence-based knowledge, the latter with providing 'infotainment' to the public. There is the worrying perception, especially among those working in science fields, that science reporting in the media is doing more harm than good; deliberate dumbing down and endless stories that have been misreported, misrepresented, or that over-played the significance of research findings. There's the MMR-vaccine-causing–autism scare, wonder cures for cancer which turn into nightmarish causes of cancer the next week, the Hadron Collider bringing about the End Times and Facebook causing syphilis, to name a few off the top of my head.

It's easy to lump journalists together in one group and demonise them as scoundrels who deliberately go out of their way to sensationalise every news story, so I was looking forward to hearing the other side of the story from David Gregory, the BBC Midlands science and environment correspondent, who was invited as guest speaker for the Birmingham Skeptics in the Pub meeting. David was refreshingly candid about the inner workings of television and was keen to stress its quick-fire and superficial nature. He did his best to reassure us that most journalists do their upmost to present accurate and objective stories, but whilst scientists and journalists could do a better job of communicating science, it's nearly impossible to say anything of note in the two minutes and 100 words afforded to science coverage on the evening news.

A running thread through the discussion was that the media just gives the public what they want: something that grabs their attention, that they feel is directly relevant to them, and, apparently most importantly, nothing too complicated. As a scientist I find it hard not to be disheartened by this pervasive idea that the general public are too dumb or disinterested to engage with science stories – it always is hard to see how other people aren't interested when you really are!

In an environment where editors and the audience want to know whether it's worth paying attention to the story within five seconds, attention-grabbing sound-bites are what it's all about. There is a fine line between making a story accessible and losing the science amongst the wackiness, but if the story doesn't have an eye-catching hook (or if the presenter's clothes or hair are too eye-catching), there is little chance of the scientific message being communicated.

The task for scientists is to perform sound research, report findings and share opinions with due care, accuracy and diligence. For the journalist it is to engage the public with exciting, but easily digestible, science stories; it is obviously not the responsibility of the media to explain the intricacies of every science story. Within science there is the expectation that the media should reflect the scientific concern for the provisional nature of knowledge; nothing is ever set in stone, progress and facts are achieved incrementally and only very rarely through the 'scientific breakthroughs' we often see on the news. It's easy to see how this translates into "scientists" change their minds from week to week, it's hard believe a word they say" in the public mind.

Making stories easily digestible also means that the media cannot spend too much time in the grey area inhabited by science. Stories often necessarily have to be presented as black or white and this leads to the thorny topic of presenting a 'balanced' argument. David expressed the problem that in a democratic organisation like the BBC, everyone who pays the license fee is, in theory, entitled to express their view, however wrong or damaging it may be. It's balance like
this that often leads to one emotive individual having more impact than a panel of scientists – how can you argue with a woman with breast cancer who is convinced it was caused by a nearby phonemast? The question of whether you should always present the other side of the argument, especially when it is unscientific, was one that some of the skeptics in the room got quite heated about, but had no real, workable answer for.

There is cause to be positive, though. With the help of charming, media-friendly personalities like Professor Brian Cox and Dr Ben Goldacre, it seems that science is undergoing a welcome resurgence ('How science became cool', http://www.guardian.co.uk/science/2010/apr/13/science-cool). More importantly, the limitless space and reach of the internet now means that viewers can be directed to follow up two-minute news stories on news sites, blogs and Twitter, and get as much science as they can handle – but only if they want it in the first place of course.

The public's perception of scientists and the science being conducted is vitally important. It is up to scientists, skeptics and sympathetic journalists like David Gregory to collaborate and do their level best to maximise the communicate of good science to the general public.
