We should stop running away from radiation by Wade Allison, Oxford Univeristy

Wade Allison nuclear and medical physicist at the University of Oxford and author of Radiation and Reason (2009) and Fundamental Physics for Probing and Imaging (2006) puts the recent concerns about the radiation from the Japanese nuclear reactors in perspective.

People worry about radiation because they cannot feel it. However, nature has a solution - in recent years it has been found that living cells replace and mend themselves in various ways to recover from a dose of radiation.

These clever mechanisms kick in within hours and rarely fail, except when they are overloaded - as at Chernobyl, where most of the emergency workers who received a dose greater than 4,000 mSv over a few hours died within weeks.

However, patients receiving a course of radiotherapy usually get a dose of more than 20,000 mSv to vital healthy tissue close to the treated tumour. This tissue survives only because the treatment is spread over many days giving healthy cells time for repair or replacement.

In this way, many patients get to enjoy further rewarding years of life, even after many vital organs have received the equivalent of more than 20,000 years' dose at the above internationally recommended annual limit - which makes this limit unreasonable.

The Narratives That Guide Our Lives by Robert James Bidinotto

Robert James Bidinotto has graciously given me permission to link to his post on Facebook about narratives. While his post is aimed at a specific audience (admirers of Ayn Rand) the points he makes applies to anyone trying to convince someone else of their position. We develop narratives about the world then embed them with our emotions. When someone challenges our narrative or don’t see the obvious wisdom of ours the emotions kick in and before you know it you’re enmeshed in a heated argument with no resolution.

The Narratives That Guide Our Lives

Most people of my philosophic persuasion believe that the power that moves individuals and cultures is, at root, philosophy. Specifically, that power lies in the "basic premises" which we accept about the world and ourselves: our beliefs about the nature of existence; about how we know things; about what constitutes good and bad; about how we should live together.


This view of the power of philosophic premises is true. However, those of my philosophic persuasion also make an additional assumption: that to change one's own life, or to "change the world," the most important and effective thing is to adopt and advocate the "right" systematic, abstract philosophy. In practice, this means: addressing thinkers and intellectuals, teaching students formal philosophy, planting "our" kind of professors in university chairs, and otherwise engaging in specifically abstract, philosophical pursuits. The tacit assumption here is that the basic philosophic premises that govern our lives are decisively communicated and absorbed in individuals and cultures by means of formal philosophical education.


That premise is mistaken.


We do not suddenly acquaint ourselves with our core worldviews in college courses, after we are already in our teens or twenties. By that time, our basic premises are usually already well-established and, in many cases, set in psychological cement.


So when, and in what form, do we really encounter and accept our foundational beliefs about ourselves and the world around us?


We do so early in life, and in the form of stories -- or what I call Narratives.


The myths that we learn in childhood, at Mother's knee, in church, in schools, in films and novels, represent primitive, fundamental interpretive stories about our world: how it works, what it means, what is right or wrong, who are the Good Guys and the Bad Guys.


These Narratives are pre-philosophical; in fact, they are acquired in their germinal forms while we are still far too young to subject them to critical analysis. They thus actually tend to determine which abstract philosophies, ideologies, economic theories, and political policies we later find appealing. These latter "feel right" to us largely because they mesh with the myths, fairy tales, parables, and stories we already absorbed during childhood.


Moreover, the more deep-rooted the myth--either personally and/or culturally--the more desperately we cling to it. We cling to it even when it may sometimes be utterly false, and lead us over a cliff. We cling to it because to challenge or criticize it means to unravel a lifetime of investments in values, choices, relationships, careers, emotions, and money. And who wants to do that?


So, like sleepwalkers, most people continue to be directed by Narratives they have never consciously identified, let alone soberly considered. Here are just a few familiar ones:


"Untouched nature is paradise; human choices and actions only upset the natural balance." That's what the Garden of Eden myth declares. Its eventual philosophical fruit? Environmentalism.


"We should take from the rich and give to the poor." That's what the tale of Robin Hood (at least, contemporary versions of it) tells us. Its eventual political fruit? Communism, socialism, and their many "progressive" variants.


"David is morally superior to Goliath." That's what the Old Testament dramatized. Its eventual global fruit? Decades of disastrous U.S. foreign policy, blindly aimed at toppling powerful regimes in favor of the "little guy" in the streets of foreign nations--even if that little guy is a jihadist wearing a suicide vest, and is eager to slaughter us.


So how, exactly, do each of us arrive at our basic Narratives?


When we're infants, we perceive the world around us strictly perceptually, and we react to "good" and "bad" in terms of raw emotions. We either like the way something makes us feels, or we don't; we're comforted, or we're uncomfortable and fearful. As our ability to integrate our perceptions of things improves, we initially do so in the form of primitive concepts.


The next stage of interpretation, though, is at the level of story-telling and myth. We do not graduate from perceptions into concepts, then go directly into philosophy. Long before we ever arrive at the ability to tie all those concepts together into anything like a systematic, abstract philosophy (for those of us who even get to that stage of thinking), we interpret the world through the stories we are told. Those may be bible stories, Aesop's fables, messages in cartoons and picture books, tales told by our parents, good-guys-vs.-bad-guys TV shows.


These provide us with our foundational interpretive template for understanding the world around us. What binds every culture or subculture together are the value-laden messages conveyed by these tales. That's because Narratives work for a culture just as they do for an individual. Looking at the glory that was Greece, for example, it is instructive to note that Homer, that society's seminal poet and storyteller, preceded by hundreds of years Aristotle, who represented the apex of formal Greek philosophical thought. The former was the true father of Greek culture, while the latter lived during its waning days. If abstract, systematic philosophy were the true fountainhead of a culture--or its salvation--then the sequence of their appearances should have been reversed.


And this should tell us where the true "power of ideas" lies: not in concepts and philosophies per se, but in concepts and philosophies as embodied, enshrined, dramatized, and propagated by compelling Narratives. In other words, the narrative medium is just as necessary and potent as the philosophic message.


This explains the enduring power of religion. Religions communicate largely on the narrative level, utilizing the power of myth, parable, and storytelling. Ask yourself: How many people are attracted to a given religion because of the incisive, intellectually satisfying arguments of its clever theologians? By contrast, how many followers instead find themselves gripped, touched, inspired, and persuaded by the stories and parables that the religion offers?


Therefore, let me offer a word of advice to people who share my own secular philosophic outlook, Objectivism.


It's futile to complain about the intractable hold of "mysticism" on people's lives. Trying to argue people out of their reigning Narrative is almost always impossible, because we all need a reigning Narrative. Instead, you have to replacea person's (or culture's) reigning Narratives(s) with something better--something more persuasive, compelling, and inspiring.


You don't have to believe me; Ayn Rand reached the same conclusion. Why did she write fiction? Read closely herRomantic Manifesto, particularly her essay, "The Psycho-Epistemology of Art." In writing about the power of "art," she is really talking about the vital role and indispensable power of Narrativesin our lives.


That is certainly the conclusion I have drawn. Rather than try hopelessly to deprive people of their existing Narratives, mystical or otherwise, I believe the only practical course is to create a rich, compelling, emotionally satisfying counter-Narrative. That is a task Rand began with her own fiction. But it is a task that should be continued by other artists--at least by those artists who wish not only to objectify their own values (which should be their primary focus), but who also would like to help create a better world.


So, a personal note of explanation: If you find less current-events commentary here lately, in part it's because I've found it to be increasingly pointless to argue philosophy, economics, and politics with most people. Why? Because we are talking past each other. You may prove a point with unassailable facts and irrefutable logic. However, the other person replies, "Yes, but . . ." Those words usually signal that you've reached the ultimate barrier to further reasoning and communication: You've challenged his Narrative. And in my experience, that is ground he'll rarely, if ever, concede.


The invisible forces directing the flow and outcomes of such debates, then, are rarely those issues under explicit discussion. Rather, they are the unidentified, unspoken, implicit Narratives that we carry with us, and which are constantly reinforced in the plots of popular novels, films, TV shows, and Sunday sermons. That is the enormous subtext of most arguments, and it poses a virtually insurmountable challenge. After all, it is very, very difficult to joust successfully and intellectually with someone when you are simultaneously fighting Adam, David, and Robin Hood.


That said, I'll return now to the personal pleasure of crafting my own counter-Narratives.

The Decline Effect is Stupid by The Last Psychiatrist

The Decline Effect Is Stupid by The Last Psychiatrist does a nice job revealing the errors in a piece titled The Truth Wears Off: Is there something wrong with the scientific method? by Jonah Lehrer

The problem isn't that the Decline Effect happens in science; the problem is that we think psychology and ecology and economics are sciences. They can be approached scientifically, but their conclusions can not be considered valid outside of their immediate context. The truth, to the extent there is any, is that these fields of study are models, and every model has its error value, it's epsilon that we arbitrarily set to be the difference between the model and observed reality.

The Last Psychiatrist doesn’t touch on this but I believe the New Yorker article is a symptom of postmodernism’s attack on science and objectivity. If the scientific method can be discounted as untrustworthy this opens the door for refusing with impunity to accept conclusions derived from this approach. To be replaced with what? That is the question.

Pajamas Media » Obama and Me

This essay presents an eloquent summary of one disillusioned former Obama supporter.

When I first heard about Obama as a rising star in the Democratic Party, a man so refreshingly different from his predecessors and contemporaries, I was intensely curious and quite favorably disposed toward the youngish, African-American legislator and author. And when I gleaned from my local newspaper that he might harbor aspirations to the White House, I found myself very much in his corner, one of his many Canadian fans. He had an effect similar to the new car smell, appropriately called “outgassing” in the trade, which is often irresistible to prospective buyers.

Naturally, I wished to learn as much as I could about the man who represented an unprecedented phenomenon on the American political scene. I soon discovered that very little of substance was known about this rara avis and so began a disciplined search for more information. Within months I had accumulated a towering stack of articles, commentaries, editorials, and diverse kinds of documentary materials, much of this stuff mere unfocused adulation and adjectival irrelevance but many of these items of a distinctly troubling nature. His autobiographies notwithstanding, I was soon caught in the grip of a profound paradox. It seemed the more I knew, the less I knew. But this “less” was more than enough to convince me, by the time he had won the Democratic nomination, that Obama was everything he presumably was not.

I had finally amassed enough documentation to determine that he was not the centrist he affected to be but a far-left ideologue, that he was a gyrating opportunist who could reverse his proclamations on a dime to suit the occasion, that he had neither knowledge of nor competence in the complexities of foreign affairs, that he was an unabashed plagiarist in his stump speeches, that there was no chance of him becoming a “post racial” president but rather a demagogue who would sharpen racial tensions, that his grasp of real-world economics was shaky to non-existent, that he was an unnervingly ignorant man (e.g. the Austrian language) as well as a showboat (e.g., the fake classical pillars), that he was associated with some of the most dubious people in the political, academic, and religious communities, and that he would waste little time putting the screws on Israel while flattering and appeasing the Islamic world.

As the lies come crashing down

This article covers events in Pakistan that have not received much attention. I found these comments within the article to be particularly enlightening and concerning.

Since taking office, the Obama administration has failed to conceive of a strategy for contending with the situation. One of the main obstacles to the formation of a coherent US strategy is the Obama administration's move to outlaw any discussion of the basic threats to US interests. Shortly after entering office, President Barack Obama banned the use of the term "War against terror," substituting it with the opaque term "overseas contingency operation."

Last April, Obama banned use of the terms "jihad," "Islamic terrorism" and "radical Islam" in US government documents.

Maybe there is an innocent explanation for this change in official language although I'm having a difficult time conjuring one.

Reflections on the Revolution in Egypt - By Victor Davis Hanson - The Corner - National Review Online

Thanks to Robert Bidinotto for this reference. As he commented when he posted this on Facebook:

Like Mubarak, Fidel is a dictator, heads a poodle military, and has been around for decades; but the media here don't call for HIS ouster. In fact, they sing the praises of his Potemkin hospitals practicing socialized "healthcare" -- which of course is denied to beaten and imprisoned dissidents.

So, what's the difference between Castro and Mubarak, which allows the former to get a pass? Simple: He's anti-American. The same goes for the thugocracy in Iran: Western intellectuals, media, and politicians only wanted "regime change" when the regime was headed by the pro-Western Shah. You haven't heard a peep from them about "democratic revolutions" since. And where are the calls for "people power" to depose the communist thug Hugo Chavez in Venezuela? Instead, he's a magnet for Hollywood leftists like Sean Penn, Danny Glover, and Michael Moore.

For the American/western left, the only distinguishing characteristic between "good" dictators and "bad" dictators" seems to be that the former are our sworn enemies, while the latter are our allies against the former. Hey, I'd love to be wrong about this. So please find me some exceptions.

“Altruism: The Moral Root of the Financial Crisis” by Richard M. Salsman

This article presents a different explanation for the current financial mess.Salsman rejects the commonly offered explanation that the inherent flaws of the free market caused the recession. His economic explanation is not unique. Others, like Thomas Sowell, have shown that government policies, not fatal flaws in capitalism, thrust us into the present mess. Salsman takes a critical step not evident in other free market based explanations. He identifies the ethical ideas behind certain policies: these ideas, accepted by Republicans and Democrats, pushed an altruist agenda in order to help folks without the necessary financial means buy houses. This was a recipe for disaster.

Those who claim greed caused are partially (and only partially) right. WhileSalsman explains how banks were "encouraged" by the certain politicians to lower lending standards I'm sure it's also true that some institutions and individuals were motivated by greed to play along and even profit from these lowered standards. This would include those who managed Freddie Mac and Freddie Mae as well as their political buddies who protected them. Greed by itself doesn't explain why the housing market imploded. Otherwise it would happen all the time and not just in the housing market. (Do we see this happening, say, in the cell phone market? Or with PC's? Or food?) You need something to prevent the market from correcting itself. In this case one of the factors was the unhealthy alliance between those who ran Freddie Mac and Freddie Mae and those who "regulated" them and the banking industries. Greed certainly was a factor but not the sole or even the main one.
