More Darwin Fish

One of the most popular posts here at Something Surprising was a silly tale about the Darwin Fish symbols that you sometimes see on people's cars.  A School of Darwin Fish has been visited surprisingly often.

Since that time I have gradually collected other versions of the symbol and although I'm not going to weave a story around them again, here are some for your enjoyment.

The Watson inconsistency and the real outrage!

(For background, see the links below)

I have little interest in 'the Rebecca Watson/Skepchick controversy', mainly because I don't care much about her personal opinions.  Unfortunately I do care how these opinions divide the so-called 'atheist community' even if I personally think that to call it a community is something of a misnomer.  I also have a particular aversion to the word Skepchick, and the egregious use of a rising tone at the end of every spoken sentence.

Watson is particularly good at sounding off about things without considering whether her public opinions are consistent with her own public behaviour.

For example, she famously complained about being propositioned by a man in an elevator at a conference, but even her own claim never suggested that she was in any danger.  (The man in question has wisely kept out of the argument.)  Richard Dawkins was drawn into this argument after making a parody of her whinging and regrettably has lost some supporters as a result (although not me).

At other times she herself can hardly be accused of being whiter than white.  A seemingly endless stream of suggestive sounding, innuendo-laden comments come from someone sounding just like her on the SGU podcast, and on her own blog and Youtube videos.  And then there was the matter of her provocative appearance in the Skepchick calendar - in the name of art and protest of course.  When it suits her, she flaunts her femininity.

Now I don't disapprove of any of these behaviours individually, nor do I say that provocative behaviour in any way invites unwanted sexual advances, but I have an uneasy feeling that her behaviours are not exactly consistent with each other.  If I spoke to my female colleagues at work in the way that she speaks, there could be a flurry of complaints.  It is a simple matter of professionalism.  Similarly, my most respected professional female colleagues make progress in life in spite of their femininity - in the sense that they would rightly be outraged if I suggested that they had gained some advantage by being female.

The problem is that being white and male, my opinion does not count for much, but after keeping quiet for so long I feel that I have to say what I think, in response to the ridiculous emergence of Atheism+.

Of course it should go without saying that I agree that it is outrageous for women in atheism and skepticism to be targeted and threatened with rape or murder by some tiny minority of lunatic extremists.  But this isn't a matter of personal opinion.  It is unequivocally a matter of law and order!  Those who threaten violence should be dealt with appropriately by the police and the court system.

Nor do I agree with any form of discrimination, positive or negative, for or against any subset of the human race. 

But it is even more outrageous that this small vocal bunch of atheistic zealots who have their heads too far up their own arses effectively accuse the majority of men of being guilty of all the above.

Isn't it?

Atheism is not a religion, but perhaps Atheism+ IS!

Following on from yesterday's post about the new vile and divisive Atheist+ movement, someone asked the reasonable question "What is the difference between Atheism+ and Secular Humanism?"  From the definition given yesterday there appears to be no big difference.

The charming, respectful and compassionate Richard Carrier says:

The problem with “Secular Humanism” is that it is an umbrella term that includes more than just “Atheists” in the Atheism+ sense: it also includes humanists of other varieties, whom we do not identify with (see related comment). And Secular Humanism as such does not specifically endorse all the elements of Atheism+ but rather a more vague and ambiguous set of values, which we might all agree with, but we happen to embrace more than that, and are less vague about it. Hence, we are Atheists plus. And we are atheists above all because we are principally (just not only) combating religious belief, identifying it (along with secular irrationality as well) as the primary threat to human happiness the world over. This is something that people who self-identify as “Secular Humanist” often don’t endorse or agree with; and even when they do, as many don’t, the label is unclear when adopted, as to which you are. Atheism+ is clear.

And of course he is right on his last point  Atheism+ is clear enough.  It represents exactly those values that we all associate with religious bigots.  I will just whisper one word . . .

Tolerance

and then shout the words of Richard Carrier himself

Reasonableness, compassion, and integrity

All of these are missing from Atheism+.  It reminds me of a religion!

Not what you say but how you say it!

A new movement is appearing in what is sometimes called 'the atheist community' in spite of the fact that it is no more a community than a group of non-stamp-collectors.  Atheism+ is causing quite a stir and it is tempting to wonder what all the fuss is about.

Apparently the movement stands for these values:  
  • Care about social justice,
  • Support women’s rights,
  • Protest racism,
  • Fight homophobia and transphobia,
  • Use critical thinking and skepticism.
Not many of us would disagree with those, although I would personally change the second to say "Support human rights" which, unless I'm mistaken, includes all women and does not discriminate against the often pilloried white, middle aged male demographic.

Richard Carrier goes on - and believe me he really can go on - in a blog post** at Free Thought Blogs, to expand on those values to include
  • Reasonableness, compassion, and integrity
And then in the (frequently offensive and far from compassionate) replies to the comments on that blog post he says:

Do you reject any of the values stated in my article? If so, which ones, and why?
If not, in what way aren’t you a part of Atheism+ movement?
Either you reject some basic human values here, or you are irrationally denying what you are, like someone who said they were sure there was no god but aren’t an atheist. As if they didn’t understand how words work.
So which is it? Are you ... [editorial yawn! I've heard enough.] . . .[basically, with us or against us]
Be honest and say.


OK - I for one will be honest and say.  I don't reject any of those 'basic human values' but I don't want anything to do with Atheism+.

Why not?  You only have to listen to the vituperative outpourings of Richard Carrier and some of his colleagues to realise that compassion is not in their nature at all.

As my mother always told me, "Its not what you say but how you say it!".

More on this topic tomorrow.

Which Atheism plus is the right one?

The new and the old A+ symbol.
The A+ symbol has been used before its recent re-emergence.  The former use was not only benign but positively altruistic.

The new incarnation might be construed as being much less positive than it looks.  Now I am left with a dichotomy.  If I wear my red NBGA tee shirt, will people mistake it for support of the Atheism+ movement?

I don't think I want that.

Just another small step

I was sad to hear last night of the death of one of the great heroes of the last century.  That's an odd sensation really, considering that Neil Armstrong was such an unknown hero to most of us.  We knew what he achieved, but since then he has kept out of the limelight very effectively.

The passing of another hero, Neil Armstrong.
The passing of another hero, Neil Armstrong.

I asked two 14 year-olds who Neil Armstrong was.  One of them knew the right answer, but only revealed it after the other said "is he that guy who was on steroids?"

On an even lighter note, read the amusing urban myth about Neil Armstrong and Mr Gorsky here.

Things Christians say, part 30: Life after death

A weekly series of responses to the things Christians say to atheists, based on the video reproduced here on 30th January 2012.  The aim is to tackle one every weekend, to give both a moderate, polite response to each question ('Piano'), followed by a more forceful rebuttal of the same question ('Forte'). 

I can't stand the idea of there being no life after death. That's why I believe in god.


Piano

The idea of life after death is one that seems common in most cultures.  Some would claim that this observation reinforces the evidence that it is true.

The main flaw with this argument is that there really is no evidence for the claim at all, so reinforcing nothing gives you the same amount of nothing.

If your faith is mainly based on this then it is fragile indeed.

***

Forte

Just because you would like to believe something comforting, it does not make that something true.  Life after death is something that we can never disprove.  All sorts of urban myths about near death experiences fuel the fire, but there are good neurological explanations for the common experiences now, and they seem far more believable than the idea that the soul can somehow survive without a brain.

Honestly!  Just because ancient peasants who knew virtually nothing about the explanation of the world around them wished to have an afterlife, why should anyone think it is true now?

In fact, I'm developing an idea that the only true atheists are the ones who do not expect to survive their own deaths, and in a day or two I will expand on the idea and link it from here.

How many people work here?

When I am asked the question "How many people work here?", my reply depends very much upon the audience.  For various reasons, I would say that this question is not asked nearly often enough.

Very few people immediately get the official answer of "about 500".

Generally my answer is "almost all of them", but . . .

How many people work here?
At least one man working!

. . . sometimes I might say "about half of them".

Some days I actually believe the final answer to be true.  A few are kept very busy (although not always fruitfully) and often they are the people who decline to delegate because they don't trust the people working for them, or because the spirit of empowerment is totally foreign to the ethos of the organisation.

Many, if not most, keep themselves busy in order to avoid being bored, often offering to take on new tasks but unable to do so because their boss falls into the 'very busy' category above.  

A few can be found deliberately avoiding doing anything useful.  Sometimes they get their just deserts.  Just a few years ago a man was bitten by a poisonous snake.  Strangely it was not revealed what he had been doing in an otherwise unoccupied and unused part of the site.  Sunbathing was one of the favorite explanations.

At a previous place of work the following cartoon went the rounds once every few years.

Too many managers
The working ethos!
Sadly not unknown in many medium/large organisations!

It might have been largely true which is very sad and very demotivating.

But at least it was funny.

What do you call a 'born again' atheist?

Evangelical Christian converts have a name for themselves, and we all have our ideas what it means for them to be 'born again'.

But what is the name for people who regain a sense of rationality and escape from religion - or those who find a cure for the 'virus of religion'?

In the case of Christianity of course the escape is not sufficiently life-threatening (for most) for the expression 'dead again' to seem politically incorrect.  After all, whatever can be born is going to die and so it seems not too inappropriate for the process of the death of faith.

Born again atheist tee-shirt

In Islam of course it is a different matter, and although I do know a few Muslim apostates quite well, I think they tend to stay fairly quiet on the matter when they are with their families and those friends who are still Islamic.  Generally they seem quite safe from those who are only 'Islamic' but could find themselves threatened by those who are 'Islamists'.

What other terms might we use?

Many people who no longer believe in the supernatural friend in the sky shy away from the label 'atheist'.  Why label yourself as something that you are not?

I would like to collect phrases that people use to describe themselves, whether serious or humorous.  I'll start off with a few and hope for comments.

I'm a member of the church of Richard Dawkins.

I'm a born-again atheist.

I'm a recovering Christian.

Any more?

Is this a God you recognise?

Here are some interesting verses from the bible.  They might not have been taught to you at Sunday School.  I wonder why.

Exodus 22:4.  If a burglar is fatally injured during the night it is not murder, but if he breaks in after sunrise and is then fatally injured then it is murder.

II Kings 2:22 - Elishah went to Bethel and was teased by 42 children.  He cursed them and they were all killed by two she-bears who came out of the forest.

Lev. 21:23 - on disabled priests.  No descendant of Aaron (the priests) with a physical defect should approach the alter (and thus profane the sanctuaries).

Judges 11:30:40 - Jepthah, son of Gilead by a prostitute, but brought back to the family in a time of crisis, made a vow with God about killing the first living thing that came out of his door if he defeated the Ammonites.  It was his daughter, and she agreed to go through with it, but she was allowed to wander in the hills for 2 months before he killed her.

2 Samuel 21:1-14 - Famine for three years had apparently been visited on the people because of the 'blood guilt' of Saul who had killed some Gibeonites.  When asked how expiation could be made, they demanded seven of Saul's sons.   Mephibosheth, son of Jonathan, son of Saul was spared because of an oath taken between David and Jonathan, but 7 others were put to death instead.  So much for human rights.

Luke 12:47-48 - Jesus teaches about the beating of slaves but completely neglects to mention that keeping those slaves at all is rather more unethical.

Mark 2:23 - Jesus and his disciples roam around the cornfields plucking ears of corn - surely theft.  This was doubly unlawful as it happened on the Sabbath when they should not have been working at all.  When challenged by the Pharisees (not for theft but because it was the Sabbath) Jesus compared it with David taking 'sacred bread' from the temple.  So that makes it alright?

Matt 21: 1-5 - Jesus' disciples took a donkey and its foal, apparently in order to fulfil a prophecy in some strange way.

Genesis 19 - The story of Lot's wife being turned into a pillar of salt is preceded by the mob wanting to rape the angels who visited Lot's family to tell them that they would be saved.   Lot offered his daughters to the mob instead.  Following the mineralisation of Lot's wife, his daughters got Lot drunk and slept with him and had his children.

Judges 19:20-30 - Rather similar to the story of Lot, two women are handed over to be raped by the mob who had initially wanted to rape the visiting men.  After being ill-treated all night, one of the women, a concubine, was cut into 12 pieces.

Proverbs 21:3 - God doesn't want sacrifices, but justice for the poor.  There is not much evidence of this elsewhere!

Psalm 14:1 - The fool hath said in his heart, There is no God.
but Matt 5:22 - . . . whosoever shall say, Thou fool, shall be in danger of hell fire.

Given these parts of the bible that seem to be mentioned rather rarely in sermons and readings in churches, do we get a better impression of the character of God?  He is said to be the source of all morality, but somehow he seems a little deficient in the areas of mercy, equality, sense of humour, and human rights.

Thank goodness he is imaginary!

A bubble of helium for the SGU

You might not know that the moon has an atmosphere, and you could be forgiven for that because we are nearly always told that that is the case.

However, it has a very thin atmosphere which is detectable with very sensitive instruments.  This week's episode #370 of the podcast The Skeptic's Guide to the Universe reported a story about a new observation from one of the satellites that is currently orbiting the moon.  Lunar Reconnaissance Orbiter's LAMP spectrometer detects helium in Moon's atmosphere is an article describing the findings.

The surprising thing about this was not the finding of helium, but that the panel was not able to understand where this helium would come from.  The podcast is generally excellent and I learn a lot from it.  If you are not a regular listener then I would recommend it to you very strongly.  (I know a few people have abandoned it recently because of the unholy row started by Rebecca Watson, but I still listen to it.  I must admit that this week's episode was more to my liking because I found none of the panel members annoying!) 

However, like many great science podcasts, SGU lacks adequate input from anyone who understands the physical sciences adequately, and time after time they miss something really obvious.

Someone else, Brad the Barbarian, beat me to the answer on the SGU forum but that's not unusual since I usually don't get the podcast download until the Saturday or Sunday after the Wednesday release.  He explained that helium is the result of alpha decay of radioactive isotopes.  I'll add a little more detail.

This process happens on the earth too, and it keeps the concentration of helium in the air fairly constant at a few parts per million.  Yes, as they said on the show, helium escapes relatively easily from the atmosphere because it is so light that it can reach escape velocity, but it is constantly being topped up from below, albeit rather slowly.

Helium - light enough to escape
Helium - light enough to escape

One of the best illustrations of this is the observation that helium is a major inconvenience to the industries that drill for natural gas.  In some fields the natural gas contains more than 20% helium.  Helium is inert and does not burn, and if the helium is not removed it has a very detrimental effect on the calorific value, and therefore the economic value of the gas that they wish to sell. 

Fortunately this is where we get most of our industrial helium from.  The unwanted contaminant has value in itself.   At the moment there is a world shortage which is causing some inconvenience. 

The helium collects in natural gas reservoirs for the same reason that the natural gas collects.  Above the oil field there is a rock layer that is impervious to gases, so they collect as a kind of bubble.  By drilling through the top of the bubble the gas is allowed out.

The helium comes from a specific type of radioactive decay of elements in the rocks below - namely alpha decay.  Some elements decay into others releasing an alpha particle.  An alpha particle only needs to collect two electrons from the environment to become a helium atom, and electrons are very easy to find if you have a positive attitude - or should I say a positive charge.

Incidentally, for the SGU panel there was a clue.  The instrument that measured this property of the moon's atmosphere is known by the acronym LAMP.  The A in that acronym is 'Alpha'.

21 Questions for Muslims

Following on from the popular post 21 Questions for Christians, here is a set of questions for Muslims.  You might recognise some of the questions from the previous post, but they apply here just as well.

Ask you about Islam? OK I will!
Ask you about Islam? OK I will!

  1. If you had to choose which comes first, Islam or the laws of the state, what is the role of sharia in a non-Islamic country, and which law takes precedence? And do Muslims have to opt in or opt out?
  2. Are you allowed to ask questions about Islam and if not, how can you ever learn about anything?  ("O ye who believe! Ask not questions about things which if made plain to you, may cause you trouble. Some people before you did ask such questions, and on that account lost their faith." (Surah 5:101-102). )
  3. Is the Qu'ran literally true and infallible?  It is so ambiguous that it is hard to argue this, but many of you do attempt to.
  4. Which verses and surah of the Qu'ran are abrogated?  If you made this clear then it would be . . . well . . . clear! 
  5. In your mosque, in what roles would it be acceptable for women to participate on an equal footing with men?
  6. What does Islam teach about homosexuality, and what are the consequences for the participants?
  7. What does Islam teach about apostasy, and what are the consequences for those who attempt to leave Islam?
  8. What do you know about the pagan origins of the black stone of the Ka'ba?  In the bible, written long before Islam was invented, Acts 19:35 mentions the goddess Diana/Artemis and a meteorite.  Does this sound familiar?
  9. Does hell exist, so that merciful Allah can torture us for ever?
  10. Did humans and apes evolve from a common ancestor?
  11. If Jesus was really rescued from the cross by an angel, wouldn't someone else have mentioned it long before the Qu'ran was written?
  12. How old is the world? (just roughly)
  13. If Allah created the universe just for us, why did he waste so much effort on the other stars and galaxies which we can never hope to reach?
  14. At what moment is the soul created?  (If at conception, please explain what happens to mono-zygotic twins.)
  15. If Islam is a religion of peace, why is there so much talk of jihad?  The inner struggle is different, as you well know, and if you use this argument then you are indulging in taqiyya again!
  16. How often have you personally used taqiyyah - lying for Islam - in your dealing with non-Muslims?
  17. If women are equal in Islam, why is it that all the spokesmen are men,and yet the most noticeable women are the apostates? (like Ayaan Hirsi Ali)
  18. If women are equal in Islam, why does the word of one man count as much as the word of two women?
  19. You probably know that progress in science was led by Islamic scholars for centuries.  Why did that progress falter and die? (If you doubt that it died, then see here.)
  20. Do you really believe in flying horses that can see in the dark?


And finally, question 21 which is the most important of all:

If you are a moderate Muslim who claims that Islam is the religion of peace, why do you not publicly call out the extremists?

It would be easy for you to do this but you don't seem to do it nearly often enough. 


Sunday Selection news

For the last two months, I have been collecting items that have interested me during the week and posting them here as my Sunday Selection.  A few people have commented that they like it, but it has not turned out to be as popular as most of the other posts.

From now on I've decided to do this via Something Surprising's Facebook page, and probably to spread them throughout the week.  You will find various new posts including this one which I found on a (new to me) blog called Nuts and Reasons.  I recommend you to pay it a visit for a selection of interesting posts.

This is athlete Jonathan Edwards talking about his loss of faith.  So many of us have had the same experience haven't we?


You can see the Facebook page without logging in, and indeed without even having a Facebook account, so don't let a dislike of Facebook prevent you from visiting.

Click on this link to go to the Facebook page 

That means that you can expect a regular post here on Sundays again.  Tonight's post will be 21 Questions for Muslims, which is a follow-on from a recent popular post 21 Questions for Christians.

Things Christians say, part 29: Why do you hate God?

A weekly series of responses to the things Christians say to atheists, based on the video reproduced here on 30th January 2012.  The aim is to tackle one every weekend, to give both a moderate, polite response to each question ('Piano'), followed by a more forceful rebuttal of the same question ('Forte'). 

Why do you hate God?


Piano

Do you hate fairies?  Do you hate Zeus, Thor, Mithra, or Osiris?

I rather suspect that the answer is that you are simply indifferent to the concepts of fairies or of other gods than your own.

And that is how atheists feel about them too.  The only difference between you and an atheist is that the atheist takes it one god further than you do. 

In order to be an atheist, we simply don't believe in gods who intervene in the natural world.

There might be another term for someone who hates God and although I can't currently think what that word might be, I do know that 'atheist' is not the one. 

***

Forte

You might think that someone who does hate God is likely to be an atheist too.  To reply to that assertion I would simply say that you need to think a bit harder about what you are saying.  How can you hate something that you do not believe in?

If you hate god you are not an atheist!
If you hate god you are not an atheist!
(Image from here)


I'm not going to ask the same question as above about your feelings toward Allah or Baal as many Christians seem to reserve a special dark place in their hearts for those particular deities.  I assert that this hatred actually demonstrates that you do believe in them and regard them as being a significant threat to your own religion.

I think you would be partly right about the threat, but wrong to believe in their existence.  It is not that it is necessary to believe in any of the deities involved, but the religions that follow other gods tend not to be favourable towards yours.  As such, human religiosity is its own enemy.  I wonder whether any wars have ever been fought over religion! (By the way, as you might have guessed, I only wonder ironically!)


Last week:  There are no contradictions in the bible.
Next week:  I can't stand the idea of there being no life after death. That's why I believe in god.

Russian Repression

Russian punk bunk 'Pussy Riot' were sentenced to 2 years in jail, for criticising Putin in the form of a prayer.  Just think about it.  The new democracy of Russia didn't take long to descend into a mafia style organisation where criticism of the godfather is not permitted.

Repression of Pussy Riot
Fighting Russian repression all around the world,
with symbolic balaclavas.

Worldwide protests were never going to make a difference of course.  Russia is too preoccupied with its own importance and the independence of its judiciary must be in question.

ID - not even a theory

Creationists dress up their wacky beliefs in a variety of ways.  'Intelligent Design' (ID) is one that has been quite popular in recent years, but in USA it was clearly recognised in the Kitzmiller vs Dover trial that is not a legitimate science.  In the findings of the court you can read:

After a searching review of the record and applicable caselaw, we find that while ID arguments may be true, a proposition on which the Court takes no position, ID is not science.

Nevertheless, ID is still heralded by supposedly 'respected' organisations like the Discovery Institute, (deliberately not linked from here as it might make them feel more important).  But even they are going to have to change terminology just as they changed the name of their Center for Science and Culture from its original name of Center for Renewal of Science and Culture (CRSC).  The word 'renewal' in that context must have give the game away!

Just listen to their podcast, 'ID The Future', a few times to hear what I mean.  You will find it a good way to exercise your skills at spotting logical fallacies in seemingly reasonable arguments and exorcise any credibility that you might lend to their point of view.

ID - not even a theory
Intelligent Design. Not even a theory!
ID is not a theory.  It is not even worthy of the name hypothesis!  It is not science, but merely another form of religious dogma dressed up as some sort of science to confuse the gullible.  It is a blanket non-explanation which only leads to regression to the further question of 'who designed the designer?'

Watch out for the next incarnation of creationism and be ready to treat it in the same way.  There are already signs of the way it might go.   We hear whining about how ID is ignored by the scientific press, and claims of discrimination against their pet ideas. We hear them asking for the teaching of the (non-existent) controversy.  I think we can tell that they are developing a new approach to replace the tired idea of Intelligent Design - although they will continue to promote the ID smokescreen in parallel.

Another blog, The Sensuous Curmudgeon, seems to share my amusement and my desire to ridicule the work of the Discovery Institute.  Have a look at this entertaining article for the New Theory of Improvident Design.

What a lot of hot air!

For a change, the hot air that I am talking about does not come from the mouth of a religious apologist, but it is contained in the hundreds of hot air balloons seen in this surprising photo taken by one of my colleagues and published here with his permission.

Hundreds of hot air balloons - a lot of hot air!

He snapped this spectacle at a ballooning event in Belgium in 2011.

Did you know that the air inside a typical hot air balloon weighs about 1 tonne?  You might ask why it still flies. 

The answer is that the cold air that it displaces is even heavier.  Yes - air weighs more that you might expect.  When the balloon is hovering at a steady height, the light, hot air inside plus the weight of the balloon and passengers is exactly the same as the weight of the cold air that it displaces.

To go up, the pilot makes the air in the balloon a little hotter (and therefore lighter), and to go down she allows it to cool a little.  The trick with going down is to avoid doing it too fast, and being able to get back almost to the balance point just before hitting the ground.

Empirical confusion - a lesson about faith based claims

One day recently I was listening to a radio programme where two people were being interviewed.  The subject hardly matters, except that it serves to illustrate a point that applies equally well to the way that people think about faith in god(s).

As it happens, it was about the effects of tobacco advertising.  This is not a subject that I find particularly interesting, but it is one that others have strong feelings about, and I could summarise the two sides of the discussion as follows: 
  • One of the protagonists in the debate was arguing that advertising attracts new people into smoking. Her argument was very much faith based.  It was simply obvious to her that this was true, and she found it impossible to accept any aspects of the opposing view.
  • Her opponent was making the point that advertising was demonstrably unsuccessful at converting people to smoking, but that it was much more successful at redistributing the market share between different brands of tobacco.  Smokers of one brand could be converted to another brand much more easily than non-smokers.  He said that he based his claim on empirical evidence.
Now I'm not going to try to judge the merits of the two arguments.  I'm not a smoker and never have been.  The point that annoyed me was that the faith-based claim was allowed a lot more air time then the evidence-based claim.  The poor guy only had to start a sentence and the interviewer (John Humphrys I think) would immediately interrupt him with another question.  It annoyed me that we were not able to hear enough about the evidence to enable us to form our own opinions.

A little later I was expressing my opinion - my outrage - about it, as sometimes I do!  I was very surprised by the reaction that I received, although in retrospect I shouldn't have been!

I was told - believe it or not - that the guy with the empirical evidence had come across as arrogant and unyielding.  The reason for this was simply that he had used the expression "empirical evidence".

Now I think you can see the parallel that I am drawing.  Those who believe in gods take the faith-based approach and they are sometimes frightened away from even considering the opposite viewpoint because of empirical evidence.  There are at least two aspects to this.
  • First, I have noticed that even intelligent and well qualified people misunderstand the term.  Empirical evidence is not just another faith claim.  It is evidence that has actually been measured, and brings you to a conclusion without having to rely on inference or deduction.  Even if it might later turn out to be wrong, it should not be ignored.  Surely it must at least be useful unless it is shown not to be true by further measurements.
  • Second, if you take the attitude in life that all claims are equally valid, as many do, then the presence or absence of evidence is not of much importance.  This is why such a way of thinking is fundamentally flawed.
The net result is that those who argue with the certainty that comes from putting the effort into detailed analysis of a topic are trumped by those who just know the truth in their hearts.  This very effectively demonstrates that rationality is not the primary trait of the human mind, as mentioned last week in my review of Michael Schermer's book, The Believing Brain.

Wisest words from Bertrand Russell
The wisest words from Bertrand Russell

The words of of one of the greatest philosophers of modern times spring to mind (as you can hear at this link)

When you are studying any matter, or considering any philosophy, ask yourself only "what are the facts, and what is the truth that the facts bear out?" Never let yourself be diverted either by what you wish to believe or by what you think would have benificent social effects if it were believed, but look only and solely at what are the facts. -- Bertrand Russell 

Shouldn't this be our crusade as rationalists?

What UK homeopaths do not want you to know

Having been fleeced by homeopaths in my more believing past (to the value of a few hundred pounds in total), and having been banned from a notable web homeopath's web site for asking perfectly polite questions, I feel that I have an axe to grind.

A few weeks ago the following letter was published on Andy Lewis's excellent site The Quackometer.

As Andy points out, The Society of Homeopaths seems rather keen that you do not see this.  Therefore I feel that it is my moral duty to defy their wishes and reproduce the letter that they sent out to their members, explaining how they have been lobbying for an exclusion to the new law that is being introduced all around Europe.  It seems that the Department of Health has re-assured them a little, but fortunately government departments are not at liberty to issue warrants to break the law, and complaints are very likely to be upheld.

Society meets ministerial team

Dear xxxxxxxx,

Thank you for your continued support with the consolidation and review of the medicines act 1968 MP Letter writing campaign.

As you know, the Society and partners have been working extremely hard behind the scenes to represent members and their best interests in this matter, including taking a leading role on engagement with the Government.

On Wednesday of this week the current campaign resulted in a meeting between our representatives and the Ministerial team from the Department of Health.

The good news is that the Department of Health continues to be in favour of patient choice and access to homeopathy as it currently stands and recognises the potential impact to patients, practitioners and homeopathic pharmacies of any changes to the way the Act is enforced.

Although during the meeting it was discussed that Section 10 would not be part of the consolidation process it was highlighted that current levels of enforcement of the act would continue in the way it has done for the past 40 years and therefore would not seek to restrict the current homeopathic provision/access routes.

To amend Section 10 it would require a unique consultation process and could therefore not form part of the consolidation process.

The Society, together with partners will continue to engage with the relevant Ministers. When the review has continued through the legislative process the Minister has offered to meet with us again to review the situation.

Nearly every MP has now been contacted and I would like to thank those members that have written to and in some cases visited their MPs to highlight the relevant issues.

Parliament is due to recess on the 17th July and we will keep you fully abreast of the situation and let you know of any further action and next steps needed in due course.

In the interim thank you for your continued support

Best regards

Phil Edmonds
Chairman
Society of Homeopaths

Please note this email is intended for Society Members only and we would kindly ask for this email not to be re-produced.

I would like to think that homeopathy is in for a rough time over the next few months.
