Differences of opinion that make you angry

July 6, 2009 Comments off

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):

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…

Unexpected Saturnian delight

March 9, 2009 Comments off

Since my initial test use of the telescope last Thursday evening, the weather here has been… let’s call it sub-optimal. Aside from the usual rain and such one gets this time of year, the British Isles seem to get more than its fair share of high-level total blanket cloud cover. It’s so frequent and pervasive that I long ago began referring to it as “English blue”. I suspect it’s something to do with the Gulf Stream that also makes this little part of the world far warmer that it should otherwise be, and makes the west coasts of Ireland and Scotland quite verdant and… soggy. Swings and roundabouts, I suppose.

Yesterday afternoon I was visiting friends for Sunday lunch (how civilised!) and we were amused by the blustery weather and hail for much of the afternoon. So I was completely unprepared, when I finally left later that evening, to look up at a crystal clear sky with only minimal, fast-moving cirrus. I drove home liked an excited little boy, knowing I’d very soon be stargazing. Since my last viewing I’ve set the telescope up correctly, read the manuals, and have an idea of what I want to view this time. It was also a good time to test my back garden as a viewing platform – the street lighting at the front being prohibitive soon after night vision is gained.

On the mental list tonight was Betelgeuse, Rigel, Orion Nebula (M42), Horsehead Nebula (IC434), Aldebaran, Sirius, Procyon, Pleiades (M45), Andromeda Galaxy (M31), Saturn and the Moon. There were a few more I’d have liked to see, but the Moon was far too bright.

With the 2 eyepieces and Barlow, I had 60-273X magnification available to me. Neither Rigel nor Sirius were visible, as the former had set below my roofline to the west and the latter hadn’t risen above the valley wall to my south, but Betelgeuse, Aldebaran and Procyon came up nicely. Though even at 273X they were just slightly brighter lights, with the exception of Betelgeuse and Aldebaran whose redness became nicely visible. The Pleiades were also very nice.

When I setup to view the Orion Nebula, because of the inversion of the image I didn’t realise at first that I was actually viewing the Running Man Nebula (NGC1977) but was very impressed with the 5 bright stars I could see against the cloudy background. I think it is more impressive than the Orion Nebula when view through a telescope.

The reason is that it appears black and white to the eye, as there’s something about the colours being indiscernible in real-time over those distances, whereas a camera’s long exposure can pick up the colours. I’d read about this, but it’s the first time I’d experienced it. I also think it was the first nebula I’d ever seen, as I don’t recall ever seeing one when I did astronomy as a child.

Next was an attempt to view the Horsehead Nebula, but I couldn’t remember exactly where it sat relation to Alnitak. So instead of viewing it, I ended up viewing the lovely Flame Nebula (NGC2024). Again, it was in black and white, so my mind’s eye filled in the colour gaps, and it was most impressive.

Then there was the Moon, and again it took my breath away. It was almost full, but there was enough shadow left to allow me to focus on the craters at the shadow’s edge and observe them in relief against the background. It was amazing to see. And when I added the 11mm eyepiece with 2X Barlow, I was able to see a very high level of detail. Smaller impact craters were easy to examine, and each Sea took up the entire view.

Tonight I was determined to view Saturn, as I missed it last week. For those of you familiar with the fantastic but now-departed TV series Firefly, you’ll know the camera technique of showing a dot in the distance, then there’s like a “click zoom” which shows the identifiable object at a distance, then another “click zoom” and it will be closeup (in the show it’s typically used in space scenes outside the ship). That’s exactly what it was like viewing Saturn. To the naked eye and when lining it up in finder-scope it was just a bright ‘star’, then viewing with a 25mm eyepiece it ‘clicked’ as a tiny but clearly identifiable yellow/biege planet with a –strikethrough– line of flattened rings, and then with a 5.5mm eyepiece (11mm with Barlow) it was much bigger and breathtaking. It just sat there, quietly inspiring awe.

And much to my surprise, I was able to identify 3 of its moons: Tethys, Titan, and Iapetus. I was initially unsure of Tethys and Iapetus, but a check of Starry Night and online confirmed it was.

Lastly, I planned to have a look at the Andromeda Galaxy, but at exactly the wrong moment my neighbours decided it was their bedtime, so switched on every light on their top floor which – when combined with the British dislike for closed curtains – meant that my back garden (the lawn part is raised) was completely flooded with bright white light for about 30 minutes. This, along with the almost full Moon, washed out my night vision – it was time to call it a night.

Even packing up under such circumstances, I was extremely happy with the night’s viewing. I’d seen most of what I’d intended, and had replaced some of the desired objects with other ones, and I’d had good opportunity to practice my constellation identification.

I’ll not pretend that I didn’t have some help, and that came in the form of the brilliant GoSkyWatch planetarium software for the iPhone. Not only does it look great, but it has an excellent database of objects and is extremely easy to use. And its “night mode” ensures that your night vision doesn’t suffer (my only niggle is that the searching and setting screens are still full brightness black/white), making it easy to use during your stargazing activity. I find this easier to see and more convenient that a planisphere, as with that I’d need to juggle the red torch, too. The software is worth every penny of its £5.99 (US$9.99) price tag.

A great evening, in all. And as the title says, both Saturn and the opportunity to view at all was an unexpected delight. Can’t wait until next time!
