"For the first time in memory, places like Egypt, Tunisia, and Yemen are starting to understand what Thomas Jefferson meant when he wrote that "when the people fear their government, there is tyranny; when the government fears the people, there is liberty." Middle East citizens have long been fearful -- but now with protesters overwhelming the streets, the regimes finally are too. Yet as people power has swept autocrats out of Tunis and Cairo, Middle Eastern regimes aren't the only ones getting nervous. Beijing is also paying rapt attention. "

"How do we tell the difference between real threats and bogus ones? (This is important for many reasons; for one, chasing fake threats takes away resources from real issues.) But it's tough to do, since evolution has given us a brain with what scientists call a "negativity bias" that makes it prone to feeling threatened. This bias developed because the ancient mammals, primates, and early humans that were all mellow and fearless did not notice the shadow overhead or slither nearby that CHOMP! killed them. The ones that survived to pass on their genes were nervous and cranky, and we are their great-grandchildren, sitting atop the food chain, armed with nuclear weapons. Your brain is continually looking for bad news. As soon as it finds some, it fixates on it with tunnel vision, fast-tracks it into memory storage, and then reactivates it at the least hint of anything even vaguely similar. But good news gets a kind of neural shrug: "uh, whatever." In effect, the brain is like Velcro for negative experiences but Teflon for positive ones. All this makes human beings super-sensitive to apparent threats. Basically, in evolution, there are two kinds of mistakes: (1) You think there is a tiger in the bushes but there isn't one, and (2) You think the coast is clear, no tiger in the bushes, but there really is one about to pounce. These mistakes have very different consequences. The first one will make you anxious, but the second one will kill you. That's why Mother Nature wants you to make the first mistake a thousand times over in order to avoid making the second mistake even once. This hard-wired tendency toward fear affects individuals, groups (from couples to multinational corporations), and nations. It makes them overestimate threats, underestimate opportunities, and underestimate resources. "

"For the second time in just over two decades, China's Communist leaders watch anxiously as a series of popular revolutions in another critical area of the world sweep out entrenched dictators and threaten to reverberate in the People's Republic. In the late 1980s and early 1990s, it was fellow Communist regimes in Eastern Europe and the Soviet Union that toppled under people power. Now it is Arab and Persian tyrants who face the wrath of the people they have oppressed for generations. Events have seemed to reach the critical tipping-point when the regime's fear of the people exceeds the people's fear of the regime. Chinese bloggers have been quick to raise the obvious question - could it happen in China? - and to begin testing the waters. Internet postings have called for silent protests in several Chinese cities to emulate Tunisia's "jasmine revolution." They have spawned a few sporadic gatherings that the authorities quickly snuffed out before they could grow - but it was a surprisingly early indication that the spark of hope for freedom in China is not extinguished."

Once, experts feared that young children exposed to more than one language would suffer "language confusion," which might delay their speech development. Today, parents often are urged to capitalize on that early knack for acquiring language. Upscale schools market themselves with promises of deep immersion in Spanish - or Mandarin - for everyone, starting in kindergarten or even before. Yet while many parents recognize the utility of a second language, families bringing up children in non-English-speaking households, or trying to juggle two languages at home, are often desperate for information. And while the study of bilingual development has refuted those early fears about confusion and delay, there aren't many research-based guidelines about the very early years and the best strategies for producing a happily bilingual child. But there is more and more research to draw on, reaching back to infancy and even to the womb. As the relatively new science of bilingualism pushes back to the origins of speech and language, scientists are teasing out the earliest differences between brains exposed to one language and brains exposed to two. Researchers have found ways to analyze infant behavior - where babies turn their gazes, how long they pay attention - to help figure out infant perceptions of sounds and words and languages, of what is familiar and what is unfamiliar to them. Now, analyzing the neurologic activity of babies' brains as they hear language, and then comparing those early responses with the words that those children learn as they get older, is helping explain not just how the early brain listens to language, but how listening shapes the early brain. Recently, researchers at the University of Washington used measures of electrical brain responses to compare so-called monolingual infants, from homes in which one language was spoken, to bilingual infants exposed to two languages. Of course, since the subjects of the study, adorable in their

Last week, the highly regarded medical journal, The Lancet, retracted a much debated 1998 study that had linked the measles, mumps and rubella vaccine to autism. The study was retracted after concerns about ethical breaches by one of the study authors. In addition, 10 of the 13 co-authors have disavowed the study's conclusions. "We fully retract this paper from the published record," The Lancet editors said in a statement. But the damage has been done. The paper has fueled fears about the risks of childhood vaccinations and autism, particularly the M.M.R. vaccine, despite numerous studies showing no link.

"Now, as the United States and other Western nations struggle to recover from a debt and property bubble of their own, a growing number of economists are pointing to Japan as a dark vision of the future. Even as the Federal Reserve chairman, Ben S. Bernanke, prepares a fresh round of unconventional measures to stimulate the economy, there are growing fears that the United States and many European economies could face a prolonged period of slow growth or even, in the worst case, deflation, something not seen on a sustained basis outside Japan since the Great Depression. "

The TOK question here is can you compare Japan of the 1990s with the US and Western Europe of today? To what degree can economists, or any human scientists, suggest that one complex situation is "like" another one?

""The kernel, the soul - let us go further and say the substance, the bulk, the actual and valuable material of all human utterances - is plagiarism." The combinatorial nature of creativity is something I think about a great deal, so this 1903 letter Mark Twain wrote to his friend Helen Keller, found in Mark Twain's Letters, Vol. 2 of 2, makes me nod with the manic indefatigability of a dashboard bobble-head dog. In this excerpt, Twain addresses some plagiarism charges that had been made against Keller some 11 years prior, when her short story "The Frost King" was found to be strikingly similar to Margaret Canby's "Frost Fairies." Heller was acquitted after an investigation, but the incident stuck with Twain and prompted him to pen the following passionate words more than a decade later, which articulate just about everything I believe to be true of combinatorial creativity and the myth of originality: Oh, dear me, how unspeakably funny and owlishly idiotic and grotesque was that 'plagiarism' farce! As if there was much of anything in any human utterance, oral or written, except plagiarism! The kernel, the soul - let us go further and say the substance, the bulk, the actual and valuable material of all human utterances - is plagiarism. For substantially all ideas are second-hand, consciously and unconsciously drawn from a million outside sources, and daily use by the garnerer with a pride and satisfaction born of the superstition that he originated them; whereas there is not a rag of originality about them anywhere except the little discoloration they get from his mental and moral calibre and his temperament, and which is revealed in characteristics of phrasing. When a great orator makes a great speech you are listening to ten centuries and ten thousand men - but we call it his speech, and really some exceedingly small portion of it is his. But not enough to signify. It is merely a Waterloo. It is Wellington's battle, in some de

Samuel Beckett, born in a suburb of Dublin in 1906, was a native English speaker. However, in 1946 Beckett decided that he would begin writing exclusively in French. After composing the first draft in his second language, he would then translate these words back into English. This difficult constraint - forcing himself to consciously unpack his own sentences - led to a burst of genius, as many of Beckett's most famous works (Malloy, Malone Dies, Waiting for Godot, etc.) were written during this period. When asked why he wrote first in French, Beckett said it made it easier for him to "write without style." Beckett would later expand on these comments, noting that his use of French prevented him from slipping into his usual writerly habits, those crutches of style that snuck into his English prose. Instead of relying on the first word that leapt into consciousness - that most automatic of associations - he was forced by his second language to reflect on what he actually wanted to express. His diction became more intentional. There's now some neat experimental proof of this Beckettian strategy. In a recent paper published in Psychological Science, a team of psychologists led by Boaz Keysar at the University of Chicago found that forcing people to rely on a second language systematically reduced human biases, allowing the subjects to escape from the usual blind spots of cognition. In a sense, they were better able to think without style. The paper is a tour de force of cross-cultural comparison, as the scientists conducted six experiments on three continents (n > 600) in five different languages: English, Korean, French, Spanish and Japanese. Although all subjects were proficient in their second language, they were not "balanced bilingual." The experiments themselves relied on classic paradigms borrowed from prospect theory, in which people are asked to make decisions under varying conditions of uncertainty and risk. For instance, native English

"VANDALS have struck a painting that depicts South African President Jacob Zuma with his genitals hanging out. Two men defaced the picture with gobs of paint, as Mr Zuma and his African National Congress sought a court order yesterday to have the painting removed from an art gallery. The case is spiced with freedom of expression on the one hand and the right to dignity on the other. It took centre stage after the painting by Brett Murray went on display in a Johannesburg gallery this month and was reported on in local media. Mr Zuma, who has a reputation for promiscuity, took the depiction of him with his private parts exposed very personally and compared himself to a rape victim. Mr Zuma himself was put on trial for rape, and acquitted, in 2006. "The portrayal has ridiculed and caused me humiliation and indignity," Mr Zuma contended in an affidavit filed yesterday with the South Gauteng High Court in Johannesburg. Presiding over the hearing in a courtroom a few kilometres from the gallery, Judge Fayeeza Kathree-Setiloane said the full three-judge bench should hear the case because the national interest and constitutional issues are at stake. South Africa's constitution protects the right to dignity as well as to freedom of expression. She said the hearing would recommence tomorrow. Mr Zuma and the ANC sought to have the painting, titled "The Spear," removed from the Goodman Gallery and to stop the newspaper City Press from displaying a photo of it on its website. Just before the hearing was scheduled to begin, two men wielding cans of red and black paint calmly walked up to the painting hanging on a gallery wall and took turns defacing it. "Now it's completely and utterly destroyed," said Iman Rappetti, a reporter for a South African TV channel who happened to be on the scene at the time as her camera rolled. Her channel showed a man in a tweed jacket painting a red X over the president's genital area and then his face. Next, a man in a hoodie smeared bl

"The only constant is change. It's the most basic fact of human existence. Nothing lasts, nothing stays the same. We feel it with each breath. From birth to the unknown moment of our passing, we ride a river of change. And yet, in spite of all evidence to the contrary, we exhaust ourselves in an endless search for solidity. We hunger for something that lasts, some idea or principle that rises above time and change. We hunger for certainty. That is a big problem. It might even be THE problem. Religions are often built around this heartache for certainty. In the face of sickness, loss and grief, a thousand dogmas with a thousand names have risen. Many profess that if only the faithful hold fast to the "rules," the "precepts" or the "doctrine" then certainty can be obtained. Fate and future can be fixed through promises of freedom from immediate suffering, divine favor or everlasting salvation. Scriptures are transformed into unwavering blueprints for an unchanging order. These documents must live beyond question lest the certainty they provide crumble. When human spiritual endeavor devolves into these white-knuckle forms of clinging they become monuments to the fear of change and uncertainty. It would be symmetrical if I could point to science as the pure antidote to the rigid rejection of uncertainty. Science, in the purest forms of its expression as a practice, holds to no doctrine other than that the world might be known. In the ceaseless pursuit of its own questioning path, science asks us to allow for ceaseless change in our ideas, beliefs and opinions. It's this aspect of science that I value more than any other. But science does not exist alone as practice. It's also a constellation of ideas that exist within culture and those ideas can gain value, in and of themselves, without connection to actual practice. In this way science becomes something more and less. For some people the idea of Science offers a trumped up certainty that yields its own false de
