A fechada da menta americana

The Closing of the American Mind

There are dangerous signs that the U.S. is turning its back on the principles of a free and open society that fostered the nation’s rise.


I was born in the midst of the Great Depression, when no one could imagine the revolutionary technological advances that we now take for granted. Innovations in countless fields have transformed society and radically improved individual well-being, especially for the least fortunate. Every American’s life is now immeasurably better than it was 80 years ago.
What made these dramatic improvements possible was America’s uniquely free and open society, which has brought the country to the cusp of another explosion of life-changing innovation. But there are dangerous signs that the U.S. is turning its back on the principles that foster such advances, particularly in education, business and government. Which path will the country take?

Over on Quora, more than 100 people have answered the question "What are the common traits of highly intelligent people?"
Some users claim to know from personal experience; others are just taking an educated guess.
As it turns out, many users gave answers that researchers would agree with.
We pulled eight of the most intriguing Quora responses and explained the science behind them -- and let's just say that we feel a lot smarter now.
Here's what we learned:

They're highly adaptable

Several Quora users noted that intelligent people are flexible and able to thrive in different settings. As Donna F Hammett writes, intelligent people adapt by "showing what can be done regardless of the complications or restrictions placed upon them."
Recent psychological research supports this idea. Intelligence depends on being able to change your own behaviors in order to cope more effectively with your environment, or make changes to the environment you're in.

They understand how much they don't know

The smartest folks are able to admit when they aren't familiar with a particular concept. As Jim Winer writes, intelligent people "are not afraid to say: 'I don't know.' If they don't know it, they can learn it."
Winer's observation is backed up by a classic study by Justin Kruger and David Dunning, which found that the less intelligent you are, the more you overestimate your cognitive abilities.
In one experiment, for example, students who'd scored in the lowest quartile on a test adapted from the LSAT overestimated the number of questions they'd gotten right by nearly 50%. Meanwhile, those who'd scored in the top quartile slightly underestimated how many questions they'd gotten right.

They have insatiable curiosity

Albert Einstein reportedly said, "I have no special talents, I am only passionately curious."
Or, as Keyzurbur Alas puts it, "intelligent people let themselves become fascinated by things others take for granted."
Research published in 2016 suggests that there's a link between childhood intelligence and openness to experience -- which encompasses intellectual curiosity -- in adulthood.
Scientists followed thousands of people born in the UK for 50 years and learned that 11-year-olds who'd scored higher on an IQ test turned out to be more open to experience at 50.
 

They're open-minded

Smart people don't close themselves off to new ideas or opportunities.Hammett writes that intelligent people are "willing to accept and consider other views with value and broad-mindedness," and that they are "open to alternative solutions."
Psychologists say that open-minded people -- those who seek out alternate viewpoints and weigh the evidence fairly -- tend to score higher on the SAT and on intelligence tests.
At the same time, smart people are careful about which ideas and perspectives they adopt.
"An intelligent mind has a strong aversion to accepting things on face value and therefore withholds belief until presented with ample evidence," says Alas.

They like their own company

Richard He points out that highly intelligent people tend to be "very individualistic."
Interestingly, recent research suggests that smarter people tend to derive less satisfaction than most people do from socializing with friends.
 

They have high self-control

Zoher Ali writes that smart people are able to overcome impulsiveness by "planning, clarifying goals, exploring alternative strategies and considering consequences before [they] begin."
Scientists have found a link between self-control and intelligence. In one 2009 study, participants had to choose between two financial rewards: a smaller payout immediately or a larger payout at a later date.
Results showed that participants who chose the larger payout at a later date -- i.e., those who had more self-control -- generally scored higher on intelligence tests.
The researchers behind that study say that one area of the brain -- the anterior prefrontal cortex -- might play a role in helping people solve tough problems and demonstrate self-control while working toward goals.

They're really funny

Advita Bihani points out that highly intelligent people tend to have a great sense of humor.
Scientists agree. One study found that people who wrote funnier cartoon captions scored higher on measures of verbal intelligence. Another study found that professional comedians scored higher than average on measures of verbal intelligence.
 

They're sensitive to other people's experiences

Smart people can "almost feel what someone is thinking/feeling,"says He.
Some psychologists argue that empathy, being attuned to the needs and feelings of others and acting in a way that is sensitive to those needs, is a core component of emotional intelligence. Emotionally-intelligent individuals are typically very interested in talking to new people and learning more about them.

A Man's LifeManly Knowledge

The 35 Greatest Speeches in History

If a man wishes to become a great orator, he must first become a student of the great orators who have come before him. He must immerse himself in their texts, listening for the turns of phrases and textual symmetries, the pauses and crescendos, the metaphors and melodies that have enabled the greatest speeches to stand the test of time.
There was not currently a resource on the web to my liking that offered the man who wished to study the greatest orations of all time-from ancient to modern-not only a list of the speeches but a link to the text and a paragraph outlining the context in which the speech was given. So we decided to create one ourselves. The Art of Manliness thus proudly presents the “35 Greatest Speeches in World History,” the finest library of speeches available on the web.
These speeches lifted hearts in dark times, gave hope in despair, refined the characters of men, inspired brave feats, gave courage to the weary, honored the dead, and changed the course of history. It is my desire that this library will become a lasting resource not only to those who wish to become great orators, but to all men who wisely seek out the great mentors of history as guides on the path to virtuous manhood.

Matemática errada

Cantor Was Wrong | There Are No Infinite Sets

The foundations of modern mathematics are flawed. A logical contradiction is nestled at the very core, and it’s been there for a century.
Of all the controversial ideas I hold, this is the most radical. I disagree with nearly all professional mathematicians, and I think they’ve made an elementary error that most children would discover.
It’s about infinity. I’ve written about infinity herehere, and here, and each article points to the same conclusion:
There are no infinite sets.
Not only do infinite sets not exist, but the very concept is logically contradictory – no different than “square circles”.
Infinite sets are quite literally enshrined into the modern foundations of math – with what’s called “The Axiom of Infinity”. It simply states that, “At least one infinite set exists.” Specifically, the set of natural numbers (1, 2, 3, 4, 5, and so on).
Superficially, it seems like the answer to the question, “How many numbers are there?” is “Infinity!”, but that’s not a precise answer – especially if we do not carefully define our terms.

Falsificação de preferências

Private Truths, Public Lies: The Social Consequences of Preference Falsification Reprint Edition

Preference falsification, according to the economist Timur Kuran, is the act of misrepresenting one's wants under perceived social pressures. It happens frequently in everyday life, such as when we tell the host of a dinner party that we are enjoying the food when we actually find it bland. In Private Truths, Public Lies Kuran argues convincingly that the phenomenon not only is ubiquitous but has huge social and political consequences. Drawing on diverse intellectual traditions, including those rooted in economics, psychology, sociology, and political science, Kuran provides a unified theory of how preference falsification shapes collective decisions, orients structural change, sustains social stability, distorts human knowledge, and conceals political possibilities.
A common effect of preference falsification is the preservation of widely disliked structures. Another is the conferment of an aura of stability on structures vulnerable to sudden collapse. When the support of a policy, tradition, or regime is largely contrived, a minor event may activate a bandwagon that generates massive yet unanticipated change.
In distorting public opinion, preference falsification also corrupts public discourse and, hence, human knowledge. So structures held in place by preference falsification may, if the condition lasts long enough, achieve increasingly genuine acceptance. The book demonstrates how human knowledge and social structures co-evolve in complex and imperfectly predictable ways, without any guarantee of social efficiency.
Private Truths, Public Lies uses its theoretical argument to illuminate an array of puzzling social phenomena. They include the unexpected fall of communism, the paucity, until recently, of open opposition to affirmative action in the United States, and the durability of the beliefs that have sustained India's caste system.

Espiões comunistas no governo de Roosevelt

"... What we learn from Evans and Romerstein is that the Soviet war and post-war gains at the West’s expense were hardly an accident.  They had ample assistance from a Roosevelt administration that was thoroughly laced with Stalin’s agents.  The agents were sufficiently numerous and highly placed that almost any theft of secrets they might have accomplished was small potatoes compared to their influence upon policy.  A central message of the book—never explicitly stated—is that there was an international conspiracy to, in effect, overthrow Western civilization.  (The authors would never point it out, but readers of the book will notice that a high percentage of the people involved were Jewish.  Readers of this review will notice, as well, that some of the key brave people sounding the alarm over this subversion were also Jewish.)  Not only was the U.S. government penetrated at the highest level, but this organized Communist network also apparently controlled key positions in the U.S. opinion-molding business...

A busca do poder

The Pursuit of Power: Technology, Armed Force, and Society since A.D. 1000 1st Edition

In this magnificent synthesis of military, technological, and social history, William H. McNeill explores a whole millennium of human upheaval and traces the path by which we have arrived at the frightening dilemmas that now confront us. McNeill moves with equal mastery from the crossbow—banned by the Church in 1139 as too lethal for Christians to use against one another—to the nuclear missile, from the sociological consequences of drill in the seventeenth century to the emergence of the military-industrial complex in the twentieth. His central argument is that a commercial transformation of world society in the eleventh century caused military activity to respond increasingly to market forces as well as to the commands of rulers. Only in our own time, suggests McNeill, are command economies replacing the market control of large-scale human effort. The Pursuit of Power does not solve the problems of the present, but its discoveries, hypotheses, and sheer breadth of learning do offer a perspective on our current fears and, as McNeill hopes, "a ground for wiser action."

"No summary can do justice to McNeill's intricate, encyclopedic treatment. . . . McNeill's erudition is stunning, as he moves easily from European to Chinese and Islamic cultures and from military and technological to socio-economic and political developments. The result is a grand synthesis of sweeping proportions and interdisciplinary character that tells us almost as much about the history of butter as the history of guns. . . . McNeill's larger accomplishment is to remind us that all humankind has a shared past and, particularly with regard to its choice of weapons and warfare, a shared stake in the future."—Stuart Rochester, Washington Post Book World 

"Mr. McNeill's comprehensiveness and sensitivity do for the reader what Henry James said that Turgenev's conversation did for him: they suggest 'all sorts of valuable things.' This narrative of rationality applied to irrational purposes and of ingenuity cannibalizing itself is a work of clarity, which delineates mysteries. The greatest of them, to my mind, is why human beings have never learned to cherish their own species."—Naomi Bliven, The New Yorker

Bastille - a grande ruptura

Solzhenitsyn Mourned Bastille Day. So Should All Christians.

The French Revolution invented radical nationalism and socialism, and launched the first modern genocide, aimed at Christians.

"... the first such modern genocide in the West took place in France, beginning in 1793. It was undertaken by modern, progressive apostles of Enlightenment and aimed at pious peasants in the Vendée region of France. By its end up to 300,000 civilians had been killed by the armies of the Republic.
This story is little discussed in France. Indeed, a devout historian who teaches at a French university once told me, “We are not to mention the Vendée. Anyone who brings up what was done there has no prospect of an academic career. So we keep silent.”

Uma nova lei estatística



Imagine an archipelago where each island hosts a single tortoise species and all the islands are connected — say by rafts of flotsam. As the tortoises interact by dipping into one another’s food supplies, their populations fluctuate.
In 1972, the biologist Robert May devised a simple mathematical model that worked much like the archipelago. He wanted to figure out whether a complex ecosystem can ever be stable or whether interactions between species inevitably lead some to wipe out others. By indexing chance interactions between species as random numbers in a matrix, he calculated the critical “interaction strength” — a measure of the number of flotsam rafts, for example — needed to destabilize the ecosystem. Below this critical point, all species maintained steady populations. Above it, the populations shot toward zero or infinity. Little did May know, the tipping point he discovered was one of the first glimpses of a curiously pervasive statistical law.

Confusões com a ciência

Why scientists believe what they do, and why the public too often doesn’t go along.
By David J. Eicher
There’s a sickness over the land. It may not, as the biblical plagues did, kill anyone. But it is corrupting millions of people with an unrealistic, warped view of the universe around them.
Every hour, every day, every week, and every month, the quality of information shared between people is seemingly getting worse, plagued by inaccuracies, exaggerations, overreactions, and outright lies. It happens in newspapers, in magazines, on television, on the Internet, and especially on social media, more and more, seemingly, as time goes on.
It’s a gross misrepresentation of science, the rational thinking process that allows us to interpret the world.
And it shows absolutely no signs of stopping. In fact, it seems to accelerate as time rolls on.
“The Big Bang never happened!”
“GMOs are bad for you and there’s a huge conspiracy to push them at consumers.” 
 “Global warming doesn’t exist.” 
“Vaccines are killing children.” 
In far too much of the media, let alone individual writings and postings, wholesale, anti-scientific sentiments seem to be winning the day.
Why, exactly, is this?

Think Twice: How the Gut's "Second Brain" Influences Mood and Well-Being

The emerging and surprising view of how the enteric nervous system in our bellies goes far beyond just processing the food we eat
U.C.L.A.'s Mayer is doing work on how the trillions of bacteria in the gut "communicate" with enteric nervous system cells (which they greatly outnumber). His work with the gut's nervous system has led him to think that in coming years psychiatry will need to expand to treat the second brain in addition to the one atop the shoulders.

O mito da superpopulação

“What most frequently meets our view (and occasions complaint) is our teeming population. Our numbers are burdensome to the world, which can hardly support us . . . . In very deed, pestilence, and famine, and wars, and earthquakes have to be regarded as a remedy for nations, as the means of pruning the luxuriance of the human race.”
This was not written by professional doomsayer Paul Ehrlich (The Population Bomb,1968). It is not found in the catastrophist works of Donella and Dennis Meadows (The Limits to Growth, 1972; Beyond the Limits, 1992). Nor did it come from the Council on Environmental Quality and the Department of State’s pessimistic assessment of the world situation, The Global 2000 Report to the President (1980).
It did not even come from Thomas Malthus, whose Essay on Population (1798) in the late eighteenth century is the seminal work to which much of the modern concern about overpopulation can be traced. And it did not come from Botero, a sixteenth-century Italian whose work anticipated many of the arguments advanced by Malthus two centuries later.
The opening quotation was penned by Tertullian, a resident of the city of Carthage in the second century, when the population of the world was about 190 million, or only three to four percent of what it is today. And the fear of overpopulation did not begin with Tertullian. One finds similar concerns expressed in the writings of Plato and Aristotle in the fourth century B.C., as well as in the teachings of Confucius as early as the sixth century B.C.

O que significa "fascismo"?

"... Fascismo é provavelmente um dos conceitos mais repetidos e pouco compreendidos da história dos dicionários políticos. Veja você mesmo. Quantas vezes você ouviu essa expressão nos últimos meses? Eu poderia apostar que não seria possível listar nos dedos de uma mão. E isso para não falar da possibilidade que você mesmo tenha sido acusado disso. Eu vivo lendo isso por aqui. Quando não como crítica aos textos que escrevo, como resposta aos comentários dos próprios leitores. Todos devidamente catalogados como fascistas. A questão é: alguém saberia realmente explicar o que exatamente é o fascismo? Ou será que todo mundo repete essa palavra sem ter a mais remota noção do que ela significa?

Guerras napoleonicas


Somewhere in the range of 3.5 million to 6 million people died as a result of the Napoleonic Wars, which lasted from 1803 to 1815. This includes both military and civilian casualties, and encompasses death from war-related diseases and other causes. Estimates of the number of soldiers killed in battle range from500,000 to almost 2 million. What happened to all of those bodies? What did Napoleonic battlefield cleanup entail?

10 Forgotten Conquerors From Ancient History

In Shelley’s famous poem Ozymandias, a broken statue lies in the empty desert, its pedestal hollowly boasting, “My name is Ozymandias, king of Kings; Look on my Works, ye Mighty, and despair!”
The conquerors on this list boasted that they had “all the lands at [my] feet” or promised to make “Egypt taste the taste of my fingers!” But in the end, they, too, have been largely forgotten. Look upon their works and despair.

O que significa ser "conservador"?

"Ser conservador, então, é preferir o conhecido ao desconhecido, o experimentado ao não experimentado, o fato ao mistério, o atual ao possível, o restrito ao irrestrito, o próximo ao distante, o suficiente ao superabundante, o conveniente ao perfeito, o sorriso presente ao êxtase utópico. Relações familiares e de lealdade serão preferidas ao fascínio de ligações mais rentáveis. Adquirir e ampliar serão menos importantes do que manter, cultivar e desfrutar. A dor da perda será mais aguda do que a excitação da novidade ou da promessa. É para igualar-se à própria sorte, para viver segundo os próprios meios, para contentar-se com o desejo de maior perfeição que tanto pertence a si mesmo quanto à própria circunstância. Em algumas pessoas essa é uma escolha natural; em outras uma disposição que se manifesta, frequentemente ou em menor grau, nas preferências e nas aversões, não sendo uma escolha intrínseca ou especificamente cultivada".

-- Michael Oakeshott (1901-1990)

Escravidão e capitalismo

The 18th-century thinkers behind laissez-faire economics saw slavery as a great example of global free trade
by Blake Smith
"... It is only in the past few decades that scholars have come to grips with how slavery and capitalism intertwined. But for the 18th-century French thinkers who laid the foundations of laissez-faire capitalism, it made perfect sense to associate the slave trade with free enterprise. Their writings, which inspired the Scottish philosopher Adam Smith’s Wealth of Nations (1776), aimed to convince the French monarchy to deregulate key businesses such as the sale of grain and trade with Asia. Only a few specialists read them today. Yet these pamphlets, letters and manuscripts clearly proclaim a powerful message: the birth of modern capitalism depended not only on the labour of enslaved people and the profits of the slave trade, but also on the example of slavery as a deregulated global enterprise..."
