I use this blog as a soap box to preach (ahem... to talk :-) about subjects that interest me.

Authors' Mistakes #11 - Vince Flynn

Earlier today, I finished reading American Assassin, by Vince Flynn.


The story, as usual, was very good. But I was disgusted by the poor quality of copy editing and proofreading.

Here below is a list of the mistakes I found in my edition (ISBN 978-1-84737-654-1). And who knows how many I missed, because when I went back to the pages I had marked, I had some difficulties in identifying the mistakes I had seen the first time.

Page 145: After a few minutes he set the alarm on his watch, turned off the bedside lamp, glanced at the loaded pistol, ... What? In the dark? Shouldn’t he first glance at the pistol and then switch the lamp off?

Page 272: The name Ohlmeyer becomes Ohimeyer.

Page 284: “Do want to walk up seven flights of stairs to go to the bathroom?” Who would say that? There should be a “you” between “Do” and “want”.

Page 290: “... you know how they can be when they’re upset. The don’t play nice. ...” Clearly, it should be “They don’t play nice”.

Page 305: Stansfield had been associates deputy director... Shouldn’t associates be singular?

Page 310: He woke up with a start, his heart pounding out of his chest, covered with sweat. Clearly, it was not his heart that was covered with sweat, but this is bad writing.

Page 402 - 1: As his deputy sat in the aisle seat next to him, he noted the way Shvets glanced at his glass of vodka, barely able to hide his contempt. This is bad writing, because you need to interpret the sentence in order to understand it. “his glass” refers to the boss’s glass, while “his contempt” refers to the deputy’s contempt. You only understand that Shvets is not glancing at his own glass of vodka when you read on.

Page 402 – 2: In “Well try, ...” , an apostrophe between “We” and “ll” is missing.

Page 405: The punched, grabbed, and pulled, finally yanking him from the space... A The instead of a They, like on page 290.

Page 421 – 1: “... More than fifty million dollars was stolen. ...” Is that how Americans (or American-speaking Russians, as the speaker was Shvets) speak? I doubt it. It should have been More than fifty million dollars were stolen.

Page 421 – 2: Shvets wanted to get out here with his life... It doesn’t make much sense. I’m pretty sure that it should have been Shvets wanted to get out of there with his life.

Such a long series of mistakes in a “number one bestseller”. This truly is a mass-market paperback. These monopolistic and overbearing publishers are so eager to earn their millions that, despite their resources, they rush books out full of mistakes. What a shame!

This is the second time I list mistakes made by Vince Flynn (see Authors' Mistakes #4).

Creativity and Research in Academia

I have been reading Sue North’s PhD thesis titled Relations of Power and Competing Knowledges Within the Academy: Creative Writing as Research (University of Canberra, 2004). In the conclusion of Chapter 2, The Conflict of the Faculties, she says:

The doxa of creative work and the doxa of research arise from different epistemological underpinnings – creativity from the unexplainable force of the imagination, and research from the logical force of understanding. [my links]

In simple terms, she said that it is common knowledge that creativity is a manifestation of imagination, while research is a process based on studying, understanding, and logical thinking. By using the word doxa, she tells us that these beliefs are so widely accepted that they don’t even need to be expressed. In other words, everybody considers them to be true.

I agree with her: most people think that way. But I believe that they do so because they don’t have a clear understanding of how people tap their creativity and what it means to do research.

The concepts that artists pull their creations out of thin air and that researchers only exercise logic are both wrong.

Let’s look at artists first. They couldn’t create anything without studying the world around them, the work of other artists, and the tools they need to do their work. Ideas don’t just spring out of the mind of an artist fully clothed and armed, like Athena out of Jupiter’s head.

As an example, consider what writing a novel involves.

The author needs to invent characters and design a plot for them, so that they can interact with each other. Some authors start with a plot and others starts with the characters, but, in either case, they must ensure that those two elements are consistent, credible (and interesting). This can only come after years of observing how people interact and trying to understand what motivates them.

And then, authors cannot write their novels with any hope of success unless they know their craft: structure, voice, pace, dialogue, to name some aspects of it. This means that they need to learn techniques, read a lot, and write a lot.

Creative writing is the Cinderella of Academia. This status of affairs reflects the almost universal opinion that, because everybody can write, studying creative writing is a trivial activity pursued by people who want to have it easy at the University.

It is only when people actually try to write something worth reading that they realise how little they know and how much they need to work in order to get any recognition.

Furthermore, to write a novel an author needs logic, discipline, and rigour, otherwise his/her four hundred pages will be full of inconsistencies, loose threads, and untruths.

In order to create realistic characters placed in a realistic environment and doing realistic actions, an author needs to do a lot of research. Most (I would say all, but I don’t want to be so absolute) authors define their characters and their plots to a level of detail that remains below the surface of the finished product. What ends up into the novel is only the tip of the iceberg.

Authors also perform another activity typical of research: experimentation. This can be in the content, the dialogue, or the form. For example, Peter Carey, in his historical novel True History of the Kelly Gang, doesn’t use a single comma, while Alessandro Baricco, in his short novel Silk, uses line breaks to control the pace and convey meaning. And if this seems too literary and abstract, how much research do you think Frank Herbert had to do in order to create the universe in which his Dune stories take place?

I’m talking about creative writing because I had a couple of non-fiction books and a couple of Science Fiction stories published. Therefore, I can talk about it with some credibility. But I’m sure that equivalent concepts apply to other creative activities.

I hope I have convinced you that creative work couldn’t exist without logical thinking, knowledge, and research. If not, think again.

Now, let’s look at research. I shall go out on a limb here and say that without imagination any type of research would be impossible.

It is standard practice in academic papers to present the results of research in a logical fashion: you write about existing results, identify a gap, and explain how your results close it. There is more to it but, in essence, research papers are logical to the core. This is especially true in Physics, the prototypical scientific discipline.

But this is not how research actually works. Most neatly presented conclusions are in reality the result of hunches, leaps, backtracking, crises, and serendipitous events (i.e., strokes of luck). Research works somewhat like solving a jigsaw puzzle: you start from the edges and the pieces you can easily recognise. Then, you fill the gaps to complete the picture. Sometimes, you feel that a piece might be right in a certain spot and place it there, hoping to have it confirmed later. But both academic papers for the scientific community and magazine articles for the rest of us present the research process as if the researchers had started the puzzle from the top-left corner and systematically worked their way to the bottom-right piece.

The key point I’m trying to express is that logic cannot add knowledge. It can be used to extract information that for any reason is still hidden in the data and, sometimes, this leads to surprising and useful results, which in turn can trigger new avenues of research. But, ultimately, truly new discoveries occur when a researcher follows a hunch and jumps over a gap in the logic. This what Edward De Bono calls Lateral Thinking. And what about the creativity that any experimental researcher needs in order to overcome the many technical (e non-technical) problems s/he encounters daily?

In other words, imagination plays an essential role in the progress of Science and Technology. The logical chain of thought is often reconstructed after the discovery has been made or a working solution found. When a scientist gets enamoured with an idea and invents an experiment to verify it, s/he will not necessarily tell you.

Think to Einstein and his special theory of relativity. He postulated the constancy of the speed of light. He certainly didn’t deduce it logically.

To conclude, successful creative endeavours require study, understanding, and logic, while research produces its best results thanks to insights, imagination, and dedication.

So, please, let’s stop perpetuating these stereotypes of wild artists and white-coated scientists!

Being a Toad

Have you ever tried to write on the spot micro-stories of 100 words or less? It’s fun! Pick a word or a phrase and then write a story around it in fifteen minutes or less. You should try it. Anyhow, this is how the following micro-story was born.

It’s not easy being a toad.

At best, people avoid me. But some do their best to crash me under a feet.

The worst are the children. Once I saw one of my friends being dismembered alive by an eager kid with a magnifying glass and a pair of scissors.

And who says that we are ugly? I can’t say that I agree with that.

Come, my dear lady, give me a kiss.

Set me free.

Seventy-six words of almost poetry!  :-)

Faith and Buddhism

I’ve started meeting with a Buddhist group. I’m an atheist, and that’s not going to change. But I don’t see Buddhism as a religion, regardless of what Wikipedia says.

I am an atheist because I don’t believe that some God has created the universe and/or has an interest in human affairs. I realise that my non-believing in God is as unjustified as the belief of Catholics, Muslims, and Jews that a God exists. Without any way of scientifically proving or disproving the existence of God (or Gods), the logical position to hold is Agnosticism.

That notwithstanding, I don’t believe that a God exists. This makes me as illogical as any believer. It annoys me a bit at an intellectual level, but I can’t help it. I also believe that it makes sense to speak of being good and virtuous (there you have a word that is completely out of fashion!), and that being good is ultimately associated to being happy or, at the very least, that you cannot be completely happy if you behave badly.

But what is good and what is bad? Or, to see it from the point of view of change, which pervades all our existences, what is better and what is worse? And more dramatically, what is right and what is wrong? I don’t know. I have been asking myself those same questions all my adult life. Does it make sense at all to speak about right and wrong? It sounds so dogmatic...

And yet, as I said, I do believe that it makes sense to distinguish between good actions and bad actions. After all, there is an almost universal agreement that lying, stealing, and killing are not thing that one should normally do.

Logical thinking doesn’t help much in these moral matters. That’s why when somebody asks me why I am a vegetarian, I reply that it feels right to me. And I’m very strict as well (uncompromising, if you like), which is a very illogical position to hold. I became vegetarian when I started looking for ways of becoming a better person. Did it work? I wouldn’t know, but I still think that it is right for me.

I suppose, following such a self-chosen rule helps me keep chaos at bay, whatever that means.

I base all my relationships on respect, and trust comes natural to me, which obviously exposes me to abuse. Like when a friend of a friend asked me to lend him a non-negligible amount of money (more than a month of my pay). I hesitated, because I didn’t really know that person and, actually, I didn’t like him. I thought I might never see my money again. But then, I asked myself: do I want to be the type of person who says no? I’d be just one more selfish bastard. But if I trust this person, I will be better for it, regardless of whether I will one day get my money back or not. Well, you guessed it: I only got back a fraction of what I lent, and that person even accused me of helping him only because I was paternalistic.

I still remember it three and a half decades later, and it still annoys me, but I know I did the right thing.

My father, whom I, regrettably, didn’t appreciate enough when he was alive, also was a trusting man. I remember that he once acted as the guarantor for a loan to a relative, and then found himself in an extremely tight spot when that relative defaulted on the repayments. My father was a good man. I am very sorry I never told him.

But I’m digressing, as usual.

All three major religions I mentioned before have prophets as emissaries of their Gods. Buddha was not a prophet, though, because Buddhism has no God. According to some tradition, some two and a half millennia ago, a man developed over the course of decades a way of reaching complete happiness. On request of others, he taught his method, thereby starting the Buddhist tradition.

I have read a bit about Buddhism, but I don’t really know much about it. What I know is that when I went to Canberra’s centre of Diamond Way Buddhism, I found myself surrounded by great people. Marvellous human beings. Never in my life had I ever met a group of people so open, so ready to welcome me among them, so eager to help without imposing anything in exchange.

Something clicked at once between us.

Theravada Buddhism teaches you techniques; in Mahayana Buddhism, the teachers act as examples; and in the Vajrayana tradition of Buddhism, to which the Diamond Way belongs, there is more emphasis on the teachers, who are supposed to inspire you.

As one of my newly-found friends said: trust must be earned. You are not expected to believe a teacher upfront. But when you see that his teachings help you again and again, you are bound to listen very carefully to what he says, and expect that a further teaching will also help you. This is what trust means.

Well, I’m new to this, but I do believe that I have in me the capability of being completely happy, and I’m willing to give it a try.

A bit of self-promotion

I know: almost a full month of silence and then only some self-promotion? It’s not so good. But I would like to be sure that you are aware of the other blog I just started.

It’s about Italian POWs held in Australia during WWII who, once repatriated to Italy, returned to Australia as migrants.

I started a PhD on that subject. That’s partly why I neglected this blog. I’ll get back to it. Actually, I’ll write an article immediately after this one.

If you want to know more about my PhD, visit my other blog at ItalianPOW.info.

That's the deal!

Some time ago, at the cafeteria of the University of Canberra, I ordered a muffin and a short black coffee and was asked to pay five dollars.


Yesterday, I went again to the same cafeteria, again ordered a muffin and a short black and was told to pay $6.70. When I picked up the coffee from the lady who was working the espresso machine, I asked: “When is the offer of $5 for a coffee and a muffin valid?”

“Why, always.” She answered.

“Then why was I asked to pay $6.70? I want my 1.70 back!” I said while smiling.

At that point, the lady who had been at the cash register came back and told me that the special offer of $5 for a sweet and a coffee was for a medium-sized coffee, not for a short one.

I pointed out that clearly the offer was designed to exclude large coffees, which cost more, not small black ones, which use less energy, less water, and no milk.

I found it so outrageous that I couldn’t let her get away with such nonsense. Finally, after some insistence from my part, she relented and refunded me my $1.70. But she was clearly annoyed and, while giving me the money, she complained “But that’s the deal...”

Authors' Mistakes #10 - 007 Tomorrow Never Dies


A couple of days ago, I watched Tomorrow Never Dies, the second 007-film with Pierce Brosnan (1997).


I was appalled to detect a huge factual mistake.

Bond is supposed to make a HALO (High Altitude Low Opening) parachute jump. Before he makes the jump, an officer tells him that he needs to keep his oxygen mask on if he wants to avoid dying of asphyxiation, because he will be jumping from five miles of altitude (26,400 feet or 8 km).

While this dialogue is taking place, they are standing in the cargo hold of a military transport airplane with the loading gate completely open. Although they should be enduring conditions comparable to those close to the summit of Mount Everest, they behave and talk as if they were in an office building.

No, no, no...

What surprises me is that the director, the actors, and the dozens/hundreds of people who contribute to making a film didn’t noticed it.

Authors' Mistakes #9 - Donna Leon

Yesterday, I finished A Noble Radiance, the 8th Brunetti novel by Donna Leon.


As usual, Leon’s crime novels with Commissario Brunetti are always a pleasure to read. But this time Leon made a mistake that invalidated the whole plot.

*** WARNING: Spoiler ***

In A Nobel Radiance, somebody dies when he opens a briefcase containing enough fissile material to build a nuclear bomb.

Now, bombs are built with either Plutonium or highly enriched Uranium 235. To build an implosion bomb, in which a volume of fissile material is highly compressed by means of conventional explosives, you need between 5 and 15 kg of fissile material.

As both Uranium and Plutonium are very dense, it is conceivable to use a briefcase to carry enough fissile material for a nuclear bomb. It would be a heavy briefcase, not least because it would be lined with lead.

So far so good, but Leon didn’t consider that fissile materials generate heat, with a power of the order of ½ kW / kg. In other words, the, say, 8kg of fissile material in Leon’s briefcase, would have continuously generated as much heat as four cloth irons set to maximum.

As lead melts at less than 330°C, I’m not even sure that, with so much heat being generated by the fissile material, the radiation-absorbing lining of the briefcase would have remained solid.

Can you imagine going around with a 20kg briefcase too hot to touch? And then shipping it to Istanbul claiming that it is a pack of ten thousand plastic syringes?

There are perhaps other issues, like the partitioning of the material to avoid approaching criticality (which would significantly increase the generated amount of radiation and heat) and the fact that the material was in the form of small blue pellets (while both U and Pu are grey), but the heat is the critical one (pun intended!)

James Kirk Street

As a Trekker, I’d love to live in James Kirk Street, even without the “T.”. Wouldn’t you?


James Kirk Street, less than 5km away from where I live, was named after James Frank Kirk (1920-1997). The ACT (Australian Capital Territory) Planning Authority explains that he was Chief Executive of Esso and of the Australian Bicentennial Authority. Kirk was made a Companion of the Order of Australia, awarded an honorary DSc from Newcastle University and became a champion of the environment as chairman of the Landcare Australia Limited.

Fair enough.

Authors' Mistakes #8 - Graham Tattersall (addendum)

I’ve given up reading Geekspeak. It is too stupid.

In four sentences that appear towards the end of Chapter 11 (pages 103 and 104), Tattersall refers three times to the bomb dropped on Hiroshima as an atomic bomb, and three times to modern multi-megaton bombs as nuclear bombs. He must think that there is a difference between an atomic bomb and a nuclear bomb!

So, here is somebody with a PhD (probably in Math) who doesn’t know that the Hiroshima bomb was a nuclear bomb.

The front flap of the book jacket says: Dr. Graham Tattersall, a confirmed and superior geek, and, later: Math has a new champion, and the Geeks a new King.

BS, I’d say.

Authors' Mistakes #8 - Graham Tattersall

Geekspeak, by Graham Tattersall is a little humorous hard-covered book containing a collection of essays about how to calculate odd things.


Tattersall, in his attempts at making complex calculations easy, cuts too many corners. For the sake of simplicity, he says things that are not right.

For example, at the beginning of Chapter 8, when estimating the number of people who die every year in the UK, he states:

You can estimate the figure quite easily from the average lifespan in this country, which is roughly 75 years — and rising. Imagine for a moment that all births in Britain stopped today, that from now onwards people die off and aren’t replaced.
Each year more die, until, after the time of the average lifespan of 75 years, there will be very few of today’s 60 million people left. So, if ages are evenly spread [my observation: a dubious assumptions, but let’s let it pass], an average of 60 million divided by 75 people will die every year. That’s about 800,000 per year.

He then comments that the actual figure is 500,000 and that the discrepancy can be explained by the fact that our lifespan is growing.

Perhaps. But there is a problem with his estimate due to his erroneous use of statistics: you cannot state that the ages of death are “evenly spread” between 0 and 75 while, at the same time, claim that “very few” live beyond the average. What average is it if there are very few people that live longer?

Tattersall’s assumption that very few people live longer than average is not only conceptually flawed, but also factually wrong, because it turns out that many people happily survive the average age of death. I looked at the US statistics and discovered that almost 60% of people live longer than average.

As an aside, you might wonder how it is possible that more than half survive the average age of death. It seems unreasonable. The reason is that the distribution is highly skewed. I will explain it with an example that, although not completely realistic, proves that for steeply decreasing distributions the number of points above the average can exceed the number of points below the average: Assume that you have a population of 100 people and that 55 of them live 60 years, 30 live 70 years, and 15 live 75 years. The average age of death is (45 x 60 + 35 x 70 + 20 x 75) / 100 = 66.5, with 55 people above average and only 45 below average. Convinced now?

Another example of his “pseudo-scientific” but confusingly imprecise presentations is in the small “Speak Geek” section at the end of Chapter 5. He states that A man who weighs 100kg at the North Pole would weigh only 99.65kg at the equator.

This is roughly correct (it’s actually close to 99.67kg). It is due to the fact that the surface of Earth, which spins at the rate of about 40,000km every 24 hours, is not an inertial system. We are kept in place by the presence of gravity. Otherwise, we would keep moving on a straight line along the tangent. From our local point of you, this appears to us as a force directed away from the axis of the Earth. This is the same apparent force that pushes us away from the centre of a car when we take a curve.

So far so good. Tattersall calls the centrifugal force an “upward ‘flinging’ force”, and that is were I have a problem. After mentioning gravitation, he explains the centrifugal force as follows: The second force is upwards, and is caused by the rotation of the Earth constantly trying to fling your body into space like a stone on a string being swung round your head.

This is misleading in too many ways to be acceptable. First of all, Earth doesn’t try to fling us anywhere. Secondly, the slingshot works because we exercise a pull on it off-centre. Therefore, to compare Earth to a slingshot is not right.

You could dismiss my objections by saying that he explains things in a colourful way and that I am just being my usual hair-splitter and boring self. But when he says that the centrifugal force is upward, he is plainly wrong. The centrifugal force is outward. It is upward at the equator, but to say it in general is badly misleading.

Finally, I would like to report a horrible mistake in Chapter 7. He starts it with the following two sentences: Captain Picard has been sorting out a spot of bother on some planet or other, while the Enterprise orbits at a safe distance. A radio command is sent to the ship: ‘Beam me up, Scotty.’

How can he not know that Scotty was the chief engineer under Captain Kirk? What a shame! And he calls himself a geek? It is painful.

I usually report problems in a book after reading it. In this case, I couldn’t hold back after reading about a third of it. I will probably have to report more...

Authors' Mistakes #7 - Lee Child (again)

Lee Child definitely knows how to write thrilling crime novels. The Visitor, published in the US with the title Running Blind, is a good read, all 500 pages of it.


I’m amazed that, despite Child’s experience and Bantam’s professional editing, a mistake still found its way into the published book. I already reported on this blog a mistake I found in another Lee Child’s book: Die Trying.

What follow is a paragraph in Chapter 22, on page 352 of my paperback edition of The Visitor:

The apartment they wanted was on the eighth floor. Reacher touched the elevator button and the door rolled back. The car was lined with bronze mirror on all four sides. Harper stepped in and Reacher crowded after her. Pressed eight. An infinite number of reflections rode up with them.

Do you see it?

It’s easy enough: When the door opens, it slides away (incidentally, rolled is not the verb I would have used, but then, who am I to criticise?)  Then, how can Reacher see that the interior of the door is lined with a mirror? He is even still standing outside the lift. Child should have swapped the sentence “The car was lined...” with “Harper stepped in...” In fact, Reacher could have only seen the inside of the door after the door closed.

Authors' Mistakes #6 - Michael Crichton & Richard Preston

I just read Micro, the novel left unfinished by Michael Crichton when he died and completed by Richard Preston.


Crichton is a great author and I enjoyed several of his novels, and especially Timeline, Airframe, and Jurassic Park. Micro is also a very entertaining story, but this time, in my opinion, he went too far with his scientific (or not) speculations.

That an extremely high magnetic field can shrink objects is difficult to take, but what happens when objects are shrunk violates the basic laws of Physics in an unacceptable way.

According to Crichton and Preston, when people are compressed, they become very light and strong. This might make for a nice story, with people jumping around like fleas and falling from great heights without getting hurt, but it is not scientifically credible.

For one thing, where does the mass go? The principle of conservation of energy-matter has been proven correct uncountable times. Even if we accept that the space between the molecules and atoms (and perhaps subatomic particles?) is reduced, why should the mass of a person be reduced as well? It doesn’t make any sense.

Then, there is the issue of body temperature and thermoregulation. Crichton and Preston mention that shrunken humans have some problems with maintaining their body temperature, but it is not an issue that one can dismiss easily.

If you reduce the linear dimensions of something by a factor of 1000 while maintaining its shape, its volume is reduced to one billionth of the original one and its surface to one millionth. This means that the surface per unit of volume would grow by a factor of 1000. No way that the human body could function under those condition. It would lose all its heat and die.

Finally, the authors don’t even try to explain how the shrinking process can be reversed. To shrink people to 1/1000 of their original size, they apply three times a strong magnetic field. Every time, the people shrink by a factor of ten. Then, without any explanation, when they apply again a magnetic field, the people return to their original sizes. This goes against logic. What is it? Three is a charm? Give me a break...

Authors' Mistakes #5 - Academic textbook on research methods

I have been reading Practical Research Methods for Media and Cultural Studies: Making People Count, by Máire Messenger Davies & Nick Mosdell, Edinburgh University Press 2006, ISBN 978-0-7486-2185-9.


On page 62, to explain methods for random sampling, the authors describe how to make a sample of 50 students from a population of 150.

When they explain the stratified method for random sampling, they say: your population list may be divided into two lists of seventy-five males and seventy-five females and you sample each list randomly until you have twenty-five of each.

The statement that out of a total population of 150 students the genders are equally split is in general not correct. You might think that it doesn’t really matter whether the two lists don’t have exactly the same length, and that the method remains valid. But this is not the case, because if there are, say, 90 males and 60 females, a sample built with 25 males and 25 females would obviously not represent the population.

Now, rather than studying a sample that represents the whole population, you might like to investigate differences between male and female students, regardless of how many of each gender are present in the population. Then, it would make sense to do the split and pick equal numbers of students from the two lists.

But how they put it, they are definitely wrong. And they keep doing it. Here is how the text continues: You then subdivide the two lists into age groups to ensure you have sufficient numbers of, say under- and over-thirties (assuming that age is relevant to your research question). As you can see, if you are going to subdivide your sample into particular demographic subgroups, your subgroups will become smaller and smaller the more categories you include, until the sample size for these subgroups cannot be seen as reliably representative.

So far so good, but now comes the blunder: For instance twenty-five females, split equally into under- and over- thirties will give you only twelve or thirteen people in each group.

How can you split equally 25 students on the basis of age (if you define the discriminating age in advance)? It’s plainly wrong.

And they go deeper and deeper in their nonsense: If you want to look at four age categories, you will get only six or so people in each age and gender subgroup.

You might think that with a couple of “on average” added in the crucial places, everything would make sense. But that is not the case, because their explanation would still imply that the age distribution of students is flat, which is not.

It’s sad to see such mistakes in academic textbooks...

Kill, kill, kill!


In memory of Emilie Parker, one of many.


The second amendment to the US Constitution says:

A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

It was adopted on 15 December 1791.

Today, we wouldn’t place a comma between subject and predicate, but grammar is not the only thing that has changed over the past 221 years.

In 1791, the USA had been independent for five years and counted fourteen states (Massachusetts, New Hampshire, Vermont, New York, Rhode Island, Connecticut, Pennsylvania, New Jersey, Delaware, Maryland, Virginia, North Carolina, South Carolina, and Georgia), plus the District of Columbia, two territories, and land disputed by Spain in the South and the U.K. in the North.

According to the 1791 census, the population of the fourteen states was 3,723,418, including 681,850 slaves. The current population of the 50 states is approximately 315 millions.

Much has been said about the American citizens’ right to bear arms. I only want to make a couple of points.

Firstly, the US doesn’t need a militia, as it was perhaps the case in 1791. They have federal, state, and local police, whose work is actually made more difficult and dangerous by all the weapons that are in circulation (an average of almost one per person).

Secondly, assault automatic weapons, contrary to what the lobby groups like the National Rifle Association claim, have nothing to do with sportsmanship. Cheap weapons designed for high fire power to kill at short range might be suitable for criminals, but have nothing to do with a civilised society.

I say: ban all automatic weapons, standardise and enforce registration laws, and make it difficult to buy ammunition.

A Prank

I don’t get it.

Two DJs called the hospital where Kate Middleton was being treated and claimed to be Queen Elizabeth.  A nurse believed them.  Then, the next day, apparently, the nurse felt so humiliated that she committed suicide.  Now, everybody blames the DJs.

It seems to me that somebody who commits suicide for having been duped must have some psychological problems.  I know that what I’m saying is not politically correct, but who in her right mind would kill herself for being victim of a prank?

I am really sorry for the nurse.  Nobody should be so desperate and alone to arrive to the point of taking their own life.  But the prank was only a trigger.  Probably the small stress that brought the nurse’s state of mind over a tipping point.  The fact that that particular nurse answered the phone was an unfortunate and tragic accident.

The DJs only did their job.  They didn’t even expect that their prank would succeed.  I understand that they feel bad.  I would too.  But they should be reassured that they are not to be blamed.

Nobody could have possibly considered the possibility that a prank call would result in a suicide.  After all this hoopla, the poor DJs will probably live the rest of their lives thinking that they caused the death of a vulnerable nurse.  But they did not.  They are not responsible for it and should receive our sympathy instead of our scorn.

Every act, even the most insignificant, can have horrible consequences, and we focus on the consequences of an act because they are observable and measurable.  The tendency of focussing on what can be measured is understandable, but in many cases also completely wrong, because very often, people “get away” with unconsidered acts that could have very serious consequences.

For example, we are always shocked when we see on TV horrific pictures of car accidents, but how many times people drive dangerously and are not caught only because, by chance, they don’t cause any carnage?  In my opinion, whether an accident occurs or not is less important than what could have happened if it had occurred.
