Differences of opinion that make you angry

July 6th, 2009 Jumile 7 comments

There have been a couple of events over the last week that have given me cause to pause and reflect, and make for an interesting article.

Last week was the Henley Royal Regatta, one of the world’s best known rowing events, that plays merry hell with my daily commute through Henley-on-Thames. So for “regatta week” I take a different route through the equally beautiful Sonning-on-Thames, home of the infamous Uri Geller, over its weak bridge crossing the Thames. This bottleneck causes a queue (i.e. what other countries call a traffic jam) of a mile or so for a couple of hours twice a day. While sitting in this queue and listening to my podcasts, I typically use such time to reflect and enjoy the natural environment in which I’m temporarily stuck, and that includes observing the antics of the cars in front and behind (in my mirror).

On Thursday I noticed the driver of the car behind had that distinctly fundagelical look about him: immaculate goatee and hair, short-sleeved buttoned shirt, oversized car, mirror shades, and gleaming teeth and plastic smile (I’ve been to the US and I’m from Australia, so I know the archetype). I saw his attention fix on my Atheist Bus Campaign sticker (available online):

Atheist Bus Campaign car sticker

He leaned forward to peer at the large text and said a few words, then lifted his sunglasses to read the smaller text and I watched as his face started to go purple and he began gesticulating and shouting to nobody, and I honestly thought that he was going to get out of his car and have a go at me. But for the traffic inching forward shortly after, he may well have done. That would have been interesting.

Last night I watched a show on Channel 4 called Revelations: Muslim School, part 2 of an 8 part series on religion’s impact on the UK, covering the lives of two young schoolgirls in a Muslim faith school. Knowing most of my friends are unaware of what happens in a non-Christian faith school, I sent out a notification on Twitter. I recommend anyone watches it — particularly if you don’t know a great deal about “everyday Islam” in the UK, as it’s remarkably neutral for a British TV documentary, and I felt the children and people portrayed in the show were representative of British Muslims with its heavy Asian influence (post-colonial immigration, etc).

My tweet was noticed by a PhD student in Sheffield, Ruth, who invited me to participate in a post-screening discussion on a website forum. Aside from Ruth and me, those present seemed to consist of a fellow humanist, a non-practising (“default”) Christian, a man who began with “Open disclosure here: I’m a Southern Baptist, proud and true” (or along those lines), and one or two others who lurked. The 60-90 minutes that followed were quite interesting, and I was happy to participate to assist in PhD research, most of which involved answering questions about what we thought of the show, concepts within it, how it was presented, any perceptions of bias or preferences for or against its approach, how we’d like to see it done differently, etc.

What I found amusing was how the Baptist kept trying to steer to conversation into opinions on Muslims, reverting to familiar cultural and religious ad hominems. Invariably we’d ignore the attempt and continue with the conversation, but he persisted for the better part of an hour. He did contribute to the discussion occasionally, but seemed more intent on getting everyone to agree with his opinions on things like the hijab: to him it was extremism — until I reminded him that mainstream Christianity required female head-covering in church until quite recently.

However, in some ways he’s right. The furore over wearing hijab is indicative of a dangerous fundamentalism in Islam, where strict adherence to the letter of the Book is of paramount importance. But he wouldn’t have been able to see that this is essentially no different to dangerous Christian fundamentalism, with some sects becoming ultra-patriarchal, women not speaking in church (1 Corinthians 14:34-35) or covering heads (1 Corinthians 11), or wars and foreign policy decisions when such people become national leaders, etc. Both lead to literal interpretations and cherry-picking of the worst parts of their respective Books, and actively discourage inquiry, investigation and understanding, and advocating Bronze Age knowledge and practises in favour of current knowledge. And in the case of those two religions in particular, they’re replete with awful, violent acts.

For the rest of us, we may not all have agreed with each others’ opinions, but we were able to play together nicely. And that’s what makes for great discussion and debate: differing opinion and the maturity to respect another’s position.

Both of these recent events reminded me of Bertrand Russell’s essay An Outline of Intellectual Rubbish, and this paragraph from it in particular (emphasis mine):

If, like most of mankind, you have passionate convictions on many such matters, there are ways in which you can make yourself aware of your own bias. If an opinion contrary to your own makes you angry, that is a sign that you are subconsciously aware of having no good reason for thinking as you do. If some one maintains that two and two are five, or that Iceland is on the equator, you feel pity rather than anger, unless you know so little of arithmetic or geography that his opinion shakes your own contrary conviction. The most savage controversies are those about matters as to which there is no good evidence either way. Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion. So whenever you find yourself getting angry about a difference of opinion, be on your guard; you will probably find, on examination, that your belief is going beyond what the evidence warrants.

Lastly, one of my company’s salespeople is a Pakistani-British Muslim who, despite being raised Muslim, has chosen to live pragmatically. He may go to mosque some Fridays for Jumu’ah, but all other aspects of at least his professional life are almost indistinguishable from any secular person (I’m not sure if he drinks alcohol or eats pork, nor is it any of my business): he doesn’t let his religion interfere with what he’s paid to do. For that he has my respect.

That’s why it surprised me this morning when he walked into the office and asked if the Peugeot in the carpark was mine, and then commented on the Atheist Bus Campaign sticker. I was pleased that he was able to joke about it, laughing how he’d “never be able to get away with that at the mosque on Fridays” and was non-confrontational about it despite much of the anti-atheist publicity and rhetoric that has flowed from self-appointed “religious authorities” since the Campaign started.

Only one of my fellow team members seems to dislike my take on religion, but then he’s the one who thinks life on earth was deliberately seeded by aliens as an experiment. So I’m crushed by his disfavour, as you might well imagine…

Equatorial delight

July 3rd, 2009 Jumile Comments off

After looking again through the boxes that my new tripod/mount came in, I stupidly realised that I actually had all the parts. That tricky foam packing with its little nooks and crannies!

So naturally I put the whole thing together and stood back to admire it sturdy heftiness, before remembering that I had a Baader solar filter I still hadn’t tried and astronomical sunset doesn’t occur until almost 21:30 local. Seemed like a good opportunity for a twofer, so I attached my 5″ OTA for the first time and took the it outside onto the front porch, where the sun was still well above my local horizon.

Never Look At The Sun

Attaching the solar filter was easy. It slid over the end where the dust cap goes, preventing unfiltered sunlight from entering the OTA, and fastens with 3 grub screws to ensure it doesn’t come loose. After I had done this I looked into the eyepiece socket (without an eyepiece) and pointed the scope at the sun until the view became brilliant, then attached the 25mm wide angle eyepiece and was rewarded with a lovely off-white image of the entire sun in the field of view. I tried the other eyepieces, though didn’t bother with the 2X Barlow, and used the fine-adjustment RA/Dec knobs on the mount to scan the edge and surface of the sun.

Unfortunately, the surface of the sun wasn’t particularly interesting because:

  • We’re in the sun’s 11 year solar minima cycle — and this cycle is particularly deep and quiescent — so there aren’t many sunspots to be seen.
  • Correspondingly, there isn’t a great deal of solar flare activity to be seen. Which is good news for the astronauts in low earth orbit.
  • The wavelengths of light seen via a solar filter provide a white image with little contrast. This can be addressed with an appropriate filter… that I don’t currently have.

What I did see was the sun up close and safely (that in itself is noteworthy) and I did see its boiling surface, particularly at the edge. Some of it would have been due to earth’s atmosphere, but there was enough there to make it enjoyable.

So the next immediate challenges are to learn how to use the equatorial mount correctly (despite inheriting an inexpensive one when I was a teenager, I never learned how to set it up properly), including the formidable setting circles, and to make the most of the plentiful summer sunlight by getting a filter that will enable more detail to be seen.

This is fun!

A new tripod for a world of difference

Celestron CG5 Mount

Posts have been few and far between lately due to being extremely busy with study (adult university distance courses take up a lot of time!), work and other things.

Over the weekend I managed to win an eBay auction for a telescope mount and tripod that I realised I’ve needed for some time: a Celestron CG5 equatorial mount on a “bomb-proof” tripod. It’s essentially what you see to the left, but without the computer and automatic tracking motor.

This became necessary because the motorised mount that came with my telescope is clearly not up to the task of reliably tracking objects — even after deciphering the instructions, carefully levelling the mount base and zeroing the unit, the drift is quite noticeable and requires regular, fiddly adjustment — and astrophotography requires either a fully-computerised AltAz mount that can track an object with pinpoint accuracy, or any level of equatorial mount. Trying to finely-adjust a motor-controlled AltAz mount to track an object is like using an Etch-A-Sketch: bearable for visual viewing, but astrophotography is out of the question. Even a cheap equatorial can track an object easily, providing the gears don’t have too much play in them and the unit is correctly configured.

A barn door mount for a camera would have done the trick, too, but I want to reap the benefits of an equatorial mount via the telescope’s eyepiece, too.

So today I have taken delivery of what appears to be 2/3 of the new mount and tripod assembly, with the joys of eBay meaning multiple packages. It’s definitely a solid, sturdy unit and I can see why the seller stated the need for something “lighter and more portable” — you wouldn’t want to carry this around to your local astronomy society’s evenings.

So once I’ve received all the parts and had a chance to test it out, I’ll post back with some pictures for your stargazing delight…
