Atheist Bus Campaign. Meh.

Friday, December 11th, 2009

As someone who believes in critical thinking, scepticism and rational enquiry it is with a little trepidation that I want to address the recent announcement of the Atheist Bus Campaign here in New Zealand.

I’ve given more thought than most would on the issue of the existence of God and, after many years of deep belief, have come to the difficult conclusion that it is just not true. For many this question is simply not an issue; they’re either completely ambivalent and would see someone as a bit wonky for believing or they know ‘deep down’ that God exists.

The campaign represents my beliefs nicely. I even respect the use of the word ‘probably’ in the opening line “There’s probably no God”. It’s nice and accurate and less like the dogma we mistrust so much in religion.

You’d think that I’d be quite enthusiastic about the campaign but I’m just not.

I think that replicating the campaign here in New Zealand smacks of an identity crisis fuelled by a little too much US Internet consumption. We just don’t have the same problems they do. A person can become the leader of our nation and not believe in an imaginary God. People don’t seem to think I’m a morally inferior person when they find out that I’m an atheist.

Sure, we have our problems. The main one I can think of regarding religion is that religions are tax exempt by default; all they have to do is “further their religion”. And there is the occasional exorcism/murder but that’s pretty much down to pig-stupidity and I doubt any amount of buses with signs would stop that. Most of our problems are down to a lack of critical thinking. Whether it be alternative medicine that just doesn’t work or our embarrassing statistics on global warming denial or our deep fear of anything not ‘natural’ (whatever that means). Here in New Zealand we have a deep distrust of science and we lack the ability to carefully weigh facts. It’s almost like we’ll back whoever comes out with the most anti-scientific sentiment as if we are backing the number-8-wire-underdog who will come through in the end with their wacky but revolutionary ideas.

I feel that the closest thing to a ‘magic bullet’ here in New Zealand is to teach children how to think critically, how to examine evidence, how not to be fooled in life, at a primary school level. Methods that we can all agree on that they can apply later in life when someone tells them about the latest healing remedy or their life-transforming revelation or the magnets that help them sleep, etc, etc.

I feel that all an Atheist Bus Campaign will do is make those who are ambivalent think that atheists are wannabe martyrs and give a platform for media-desperate fundamentalists who will come off looking semi-respectable in contrast.

To those running the campaign I say good luck and that I agree with what you are saying. I just don’t think it’s going to achieve what you think it’s going to achieve.

Dogma

Thursday, April 16th, 2009

No one believes that they are dogmatic. We’re all far too reasonable for that carry on. But we can all point to a number of other people who we would term as dogmatic and, with a little imagination, we should be able to understand that they probably don’t think they are dogmatic. This leaves us with a dilemma; how do we know that we are not being dogmatic ourselves? If we can see others acting dogmatically who are unaware of it then, chances are, we could be too.

By ‘dogmatic’ I am describing an absolutist kind of belief that, if I could summarise in my own words, boils down to the fact that you would really rather hold to what you believe than accept an alternative even if the alternative is true. Dogma is the belief you refuse to interrogate.

Dogmatism can get in the way of new truths. The reason for this is that if you are unwilling to honestly put a belief to the test then you will never find out if that belief happens to be false. A valid argument can be made that perhaps there are some beliefs that we’d be better off clinging to rather than risking finding out a truth that would cause you great unhappiness. Would you like to find out that your partner cheated on you all those years ago? What if we discover that we are really just a brain in a jar somewhere living a simulation? What if God really is imaginary? What if God really is real? Whether we dare to search for the truth of a particular matter is a personal decision. But if we refuse to honestly put our beliefs to the test then we ought to show a little more humility when telling others what we ‘know‘ to be true.

So, assuming we do want truth, how do we avoid dogmatism? The best way I can think of is to actually value truth over any existing belief. This can be excruciating, especially when a belief is foundational to any meaning you get out of life. I found it very difficult many years ago to say to myself in all honesty that I would hold truth higher than my belief in the existence of God. If you’ve never believed in God you’ll probably struggle to understand the significance of this but, to a believer, God is truth and so it can seem a kind of fundamental blasphemy to say that you would even challenge the idea. If you do believe in God, fear not, many respectable people have done what I did and kept their belief afterwards and I greatly respect them for it.

Other than valuing truth over existing beliefs I’ve come across another technique that can help to break the emotional attachment we often develop with our dearly-held beliefs. That is to regularly switch perspectives or, “state the opposite”. An example of this is to first say what you believe i.e. “Labour has the best health policies” and then say the opposite i.e. “National has the best health policies” or, “Act has the best health policies” and try to mean it. You can do this with just about any belief in which you are tempted to take sides and it really can help to make you more objective because it can lessen the effects of the ‘in-group/out-group’ factor.

Does anyone have any other good tips or tricks for finding truth that can be used by anyone regardless of their starting assumptions?

How Polarisation Can Get In The Way Of Truth

Wednesday, April 15th, 2009

In a perfect world, when faced with a contentious issue, we would assimilate the facts, weigh them against each other and come to a reasonable consensus (pending further information, of course). We don’t live in a perfect world however and I’ve observed in myself and in others that we often tend to treat our existing beliefs about the way the world works as if it were our favourite football team; we’ll stand behind them through good times and bad, through confirmatory and contradictory evidence.

This is a fairly natural thing to do and if we are aware of our own confirmation bias we can do a lot to gradually eliminate those ideas we previously held to be true but which were, in fact, false.

However, I’ve noticed that when two people attempt to discuss a contentious issue from two very different starting assumptions, instead of fostering a willingness to seek the truth regardless of the impact to our existing beliefs, we are driven further toward defending them against this new ‘enemy’.

I think that if our goal is truth then we ought to spend most of our time challenging our existing beliefs in dialogue with people with whom we have much in common. That way we’ll be less inclined to go into defensive mode and more likely to gracefully discard what was previously an incorrect belief.

This would mean that in many cases there would have to be a certain level of exclusivity to discussions but I think it would go a long way toward self-improvement even though it may take a very long time to unravel long-held presuppositions.

I want to be able to thrash out what I see as difficulties to do with consciousness or first causes without having to deal with the distraction of religious dogma or new age pseudo-science and, more importantly, I’d imagine that there are many conversations that other people would like to have without me jumping in and blurting out what I know must be true.

So, for those of you who have found me an irritation in the past, I hope to be less in your face with what I perceive to be the absolute truth. If you think I’ve got something wrong and you hold very similar starting assumptions to me then please feel free to rigorously discuss your ideas with me. If you hold very different starting assumptions please try to allow for the fact that you may be wrong and I will try my best to do likewise. We may, after all, both be wrong.

In a perfect world we should be happier to learn that we have been wrong than that we have ‘won’ an argument.

Steorn’s Orbo

Friday, April 3rd, 2009

orboBack in August 2006 a company called Steorn took out a full-page advert in The Economist claiming they had developed a free energy device – charmingly called an Orbo – and were looking for qualified scientists to be a part of their validation process. Steorn is based in Dublin, Ireland and is headed up by a guy called Seán McCarthy.

The claim of free energy is a big one. Many people have attempted it – even Da Vinci tried his hand at it – but so far no one has succeeded. Free energy isn’t the same as solar energy or wind energy, it’s an entirely different beast. There is a law in physics called The Conservation of Energy which says that the energy contained within a closed system will remain constant. This is not a law to be trifled with as it has an enormous amount of strong scientific evidence to support it and, so far, not a shred of evidence against it. Some physicists have even said that a violation of this law “would undermine not just little bits of science – the whole edifice would be no more”.

What Steorn are claiming is that they have a device which, isolated from any external energy source, will produce more energy than it requires to run. This is huge. This would solve all of the world’s energy problems. Imagine it; hook this thing up to a 9 volt battery and it will produce more than 9 volts which you will be hook up to another Orbo (or even back into itself, thus removing the need for a battery in the first place) and so on, giving you potentially infinite energy.

So, should we believe them? After all, scientific knowledge is continually being added to and there have been plenty of times in the past where the ’scientists’ of the day have scoffed at a new idea. Could this be the next major development in our understanding of the universe? A whole new paradigm? They seem like really genuine people and qualified engineers have been singing their praises. There doesn’t seem to be any overt financial scam going on either.

What we should do is be sceptical (or, ’skeptical’ if you live in the US). This simply means that we should demand good evidence before believing the claim. And there are some strong warning signs that we should heed as well:

  1. So far there have been thousands of claims of free energy but none have succeeded
  2. The most alluring of these claims have involved magnets, the Orbo does too
  3. We have not heard back from their panel of science validators
  4. Good science is usually done in the public domain where peer review is encouraged rather than by going directly to the media
  5. They attempted a demonstration in July 2007 but it was a complete failure
  6. They have provided no explanation for how they have been able to achieve free energy
  7. So far all we have is anecdotal evidence
  8. It goes against some of the best-established science

My thoughts are that they probably genuinely believe in what they are doing (I like to look for the good in people) but that they are either accessing an external source of energy they hadn’t considered or that they are subconsciously allowing themselves to overlook another critical issue in their excitement. I’m deeply suspicious given their reluctance to demonstrate the technology and their unconventional approach of avoiding the public rigour of the scientific community and instead choosing to talk to the media (who are much more gullible).

I would love for them to have broken a strongly-held law of physics, especially given the potential benefit our world could gain. But I’m going to need some very strong evidence before I’m convinced.

I’ll leave you with Robert Park’s Seven Warning Signs of Bogus Science:

  1. The discoverer pitches the claim directly to the media
  2. The discoverer says that a powerful establishment is trying to suppress his or her work
  3. The scientific effect involved is always at the very limit of detection
  4. Evidence for a discovery is anecdotal
  5. The discoverer says a belief is credible because it has endured for centuries
  6. The discoverer has worked in isolation
  7. The discoverer must propose new laws of nature to explain an observation

Review of The Secret

Friday, January 9th, 2009

Here’s an excellent review of that over-read sack of cack, The Secret that I found on Amazon by user Ari Brouillette.

Please allow me to share with you how “The Secret” changed my life and in a very real and substantive way allowed me to overcome a severe crisis in my personal life. It is well known that the premise of “The Secret” is the science of attracting the things in life that you desire and need and in removing from your life those things that you don’t want. Before finding this book, I knew nothing of these principles, the process of positive visualization, and had actually engaged in reckless behaviors to the point of endangering my own life and wellbeing.

At age 36, I found myself in a medium security prison serving 3-5 years for destruction of government property and public intoxication. This was stiff punishment for drunkenly defecating in a mailbox but as the judge pointed out, this was my third conviction for the exact same crime. I obviously had an alcohol problem and a deep and intense disrespect for the postal system, but even more importantly I was ignoring the very fabric of our metaphysical reality and inviting destructive influences into my life.

My fourth day in prison was the first day that I was allowed in general population and while in the recreation yard I was approached by a prisoner named Marcus who calmly informed me that as a new prisoner I had been purchased by him for three packs of Winston cigarettes and 8 ounces of Pruno (prison wine). Marcus elaborated further that I could expect to be [...] raped by him on a daily basis and that I had pretty eyes.

Needless to say, I was deeply shocked that my life had sunk to this level. Although I’ve never been homophobic I was discovering that I was very rape phobic and dismayed by my overall personal street value of roughly $15. I returned to my cell and sat very quietly, searching myself for answers on how I could improve my life and distance myself from harmful outside influences. At that point, in what I consider to be a miraculous moment, my cell mate Jim Norton informed me that he knew about the Marcus situation and that he had something that could solve my problems. He handed me a copy of “The Secret”. Normally I wouldn’t have turned to a self help book to resolve such a severe and immediate threat but I literally didn’t have any other available alternatives. I immediately opened the book and began to read.

The first few chapters deal with the essence of something called the “Law of Attraction” in which a primal universal force is available to us and can be harnessed for the betterment of our lives. The theoretical nature of the first few chapters wasn’t exactly putting me at peace. In fact, I had never meditated and had great difficulty with closing out the chaotic noises of the prison and visualizing the positive changes that I so dearly needed. It was when I reached Chapter 6 “The Secret to Relationships” that I realized how this book could help me distance myself from Marcus and his negative intentions. Starting with chapter six there was a cavity carved into the book and in that cavity was a prison shiv. This particular shiv was a toothbrush with a handle that had been repeatedly melted and ground into a razor sharp point.

The next day in the exercise yard I carried “The Secret” with me and when Marcus approached me I opened the book and stabbed him in the neck. The next eight weeks in solitary confinement provided ample time to practice positive visualization and the 16 hours per day of absolute darkness actually made visualization about the only thing that I actually could do. I’m not sure that everybody’s life will be changed in such a dramatic way by this book but I’m very thankful to have found it and will continue to recommend it heartily.
