7 Free Documentaries: One Second to the Next, Evolution vs. God, DEFCON, Turnstile, BioBricks, Modern Spies, Nazi Concentration Camps.


If the videos aren't visible in the emails, see them on the website:  http://www.dustcircle.com

From One Second to the Next
These are some of the stories that Werner Herzog portrayed in this It Can Wait documentary dedicated to horrors and victims of texting and driving.



















Evolution Vs. God
Evolution Vs. God is a documentary trying to challenge the theory of evolution. Evangelical leader Ray Comfort, known as the bananaman, interviews evolution proponents (mostly students) from different universities in the United States and tries to expose the so called “unscientific nature” of evolution which he refers to as a “blind faith”, not science. The film tries to show intelligent design as a competing theory and suggests that the academe continues to bully intelligent design as an option. The film also aims to get some evidence for Macroevolution.



















DEFCON: The Documentary
DEFCON is the world’s largest hacking conference, held in Las Vegas, Nevada. In 2012 it was held for the 20th time. The conference has strict no-filming policies, but for DEFCON 20, a documentary crew was allowed full access to the event. The film follows the four days of the conference, the events and people (attendees and staff), and covers history and philosophy behind DEFCON’s success and unique experience.


Turnstile
Turnstile is focused on women involved in the criminal justice system and drug policy reform. The 36 minute film offers an exploration of three women’s experiences with addiction and incarceration, and interviews with other women that have been working for decades on criminal justice reform.


BioBricks: Building Blocks of Life
In the race to decode the human genome, scientists have long developed the tools that allow them to read and influence the building blocks of life. Scientists at the Max Planck Institute are able to decode the genome of Neanderthals and compare it with the human genome. Synthetic biology is no longer just practiced in university laboratories anymore. The next step could be for scientists to bring extinct species back to life – maybe even Neanderthals. Things that aren’t ethically defensible today could become normal in the future.


Modern Spies
From James Bond to Jason Bourne, the fictional world of spying is a world of danger and deception, glamour and lies. But how does the myth compare with the reality?


Nazi Concentration Camps
The Nazi Concentration Camps documentary was filmed in 1945 and entered as evidence at the Nuremberg Trials of Rudolf Hess, Hermann Göring, and 22 other Nazi officials in the aftermath of World War II. It revealed a stark, horrifying image of the atrocities of the Holocaust and ensured than no one would ever doubt the meaning of the charge, “crimes against humanity.”

President Obama to United Nations: ‘We Do Not Ban Blasphemy’

President Obama has disappointed nonbelievers and those who take seriously the concept of church-state separation many times. In his participation in the National Prayer Breakfast, in his continuation and expansion of the Bush-spawned “faith-based initiatives,” and his general pandering to religious figures, such has his inclusion of the risible Rick Warren at his inauguration.

Why are Internet Freedom Fighters always fighting against the Internet Freedom of Artists?

We’re always a little amazed when site like Hypebot takes up the fight for internet freedom, as long as that freedom does not include artists rights.

Will Israel Blow Up Something and Falsely Blame It On Iran?

According to U.S. officials, Israel is training and supporting Iranian terrorists who are trying to topple the Iranian government. Those Israeli-funded terrorists have faked documents to falsely indicate that Iran is building a nuclear bomb. Israel has admitted to previous use of false flag attacks to justify war against Middle Eastern nations.

It's Time for Conservatives to Stop Whining About Relativism! (And Take on the Experts!)

The Continuing Battle Over Blasphemy Laws

I'm surprised to still be writing about blasphemy laws, but it seems the idea just won't die. At the United Nations this week, the elected leaders of newly democratic Egypt and Yemen called for restrictions on free speech, in addition to similar demands from Turkey and other Islamic-majority nations. Russia, too, is advocating for laws that would criminalize criticism of religion, saying that "the feelings of the faithful must be protected by the state" (HT: IHEU). Unfortunately this doesn't surprise me, since under Vladimir Putin, Russia has basically reverted to the theocratic dictatorship it was in the days of the czars. Even Greece is prosecuting a man for the most harmless poke at religion imaginable, using archaic blasphemy laws.

Climate change already harming the global economy

According to the Climate Vulnerability Monitor – a report by Spanish non-profit organisation DARA – in 2010 climate change shaved 1.6 per cent off global gross domestic product. The figure was calculated by adding the harmful effects of climate change to the problems of the carbon-based economy, such as air pollution.

Does the Universe Need God?
In many religious traditions, one of the standard roles of the deity has been to create the universe.  The first line of the Bible, Genesis 1:1, is a plain statement of this role.[1] Much has happened, both in our scientific understanding of the universe and in the development of theology, since that line was first written.  It's worth examining what those developments imply for the relationship between God and cosmology.


Financially troubled parts of Europe consider taxing church properties

Cash-strapped officials in Europe are looking for a way to ease their financial burden by upending centuries of tradition and seeking to tap one of the last untouched sources of wealth: the Catholic Church.

On the Freedom to Offend an Imaginary God

The latest wave of Muslim hysteria and violence has now spread to over twenty countries. The walls of our embassies and consulates have been breached, their precincts abandoned to triumphant mobs, and many people have been murdered—all in response to an unwatchable Internet video titled “Innocence of Muslims.” Whether over a film, a cartoon, a novel, a beauty pageant, or an inauspiciously named teddy bear, the coming eruption of pious rage is now as predictable as the dawn. This is already an old and boring story about old, boring, and deadly ideas. And I fear it will be with us for the rest of our lives.

Nothing, however vile, justifies censorship

Evangelicals Question The Existence Of Adam And Eve : NPR

by Barbara Bradley Hagerty
[REPRINT]

Download Audio

Let's go back to the beginning — all the way to Adam and Eve, and to the question: Did they exist, and did all of humanity descend from that single pair?

According to the Bible (Genesis 2:7), this is how humanity began: "The Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul." God then called the man Adam, and later created Eve from Adam's rib.

Polls by Gallup and the Pew Research Center find that four out of 10 Americans believe this account. It's a central tenet for much of conservative Christianity, from evangelicals to confessional churches such as the Christian Reformed Church.

But now some conservative scholars are saying publicly that they can no longer believe the Genesis account. Asked how likely it is that we all descended from Adam and Eve, Dennis Venema, a biologist at Trinity Western University, replies: "That would be against all the genomic evidence that we've assembled over the last 20 years, so not likely at all."

Researching The Human Genome

Venema says there is no way we can be traced back to a single couple. He says with the mapping of the human genome, it's clear that modern humans emerged from other primates as a large population — long before the Genesis time frame of a few thousand years ago. And given the genetic variation of people today, he says scientists can't get that population size below 10,000 people at any time in our evolutionary history.

To get down to just two ancestors, Venema says, "You would have to postulate that there's been this absolutely astronomical mutation rate that has produced all these new variants in an incredibly short period of time. Those types of mutation rates are just not possible. It would mutate us out of existence."

Venema is a senior fellow at BioLogos Foundation, a Christian group that tries to reconcile faith and science. The group was founded by Francis Collins, an evangelical and the current head of the National Institutes of Health, who, because of his position, declined an interview.

And Venema is part of a growing cadre of Christian scholars who say they want their faith to come into the 21st century. Another one is John Schneider, who taught theology at Calvin College in Michigan until recently. He says it's time to face facts: There was no historical Adam and Eve, no serpent, no apple, no fall that toppled man from a state of innocence.

"Evolution makes it pretty clear that in nature, and in the moral experience of human beings, there never was any such paradise to be lost," Schneider says. "So Christians, I think, have a challenge, have a job on their hands to reformulate some of their tradition about human beginnings."

'Fundamental Doctrines Of The Christian Faith'

To many evangelicals, this is heresy.

"From my viewpoint, a historical Adam and Eve is absolutely central to the truth claims of the Christian faith," says Fazale Rana, vice president of Reasons To Believe, an evangelical think tank that questions evolution. Rana, who has a Ph.D. in biochemistry from Ohio University, readily admits that small details of Scripture could be wrong.

"But if the parts of Scripture that you are claiming to be false, in effect, are responsible for creating the fundamental doctrines of the Christian faith, then you've got a problem," Rana says.

Rana and others believe in a literal, historical Adam and Eve for many reasons. One is that the Genesis account makes man unique, created in the image of God — not a descendant of lower primates. Second, it tells a story of how evil came into the world, and it's not a story in which God introduced evil through the process of evolution, but one in which Adam and Eve decided to disobey God and eat the forbidden fruit.

Albert Mohler, president of Southern Baptist Theological Seminary in Louisville, says that rebellious choice infected all of humankind.

"When Adam sinned, he sinned for us," Mohler says. "And it's that very sinfulness that sets up our understanding of our need for a savior.

Mohler says the Adam and Eve story is not just about a fall from paradise: It goes to the heart of Christianity. He notes that the Apostle Paul (in Romans 5 and 1 Corinthians 15) argued that the whole point of Jesus' crucifixion and resurrection was to undo Adam's original sin.

"Without Adam, the work of Christ makes no sense whatsoever in Paul's description of the Gospel, which is the classic description of the Gospel we have in the New Testament," Mohler says.

Intellectual Rift

That's only true if you read the Bible literally, says Dennis Venema at Trinity Western University. But if you read the Bible as poetry and allegory as well as history, you can see God's hand in nature — and in evolution.

"There's nothing to be scared of here," Venema says. "There is nothing to be alarmed about. It's actually an opportunity to have an increasingly accurate understanding of the world — and from a Christian perspective, that's an increasingly accurate understanding of how God brought us into existence."

This debate over a historical Adam and Eve is not just another heady squabble. It's ripping apart the evangelical intelligentsia.

"Evangelicalism has a tendency to devour its young," says Daniel Harlow, a religion professor at Calvin College, a Christian Reformed school that subscribes to the fall of Adam and Eve as a central part of its faith.

"You get evangelicals who push the envelope, maybe; they get the courage to work in sensitive, difficult areas," Harlow says. "And they get slapped down. They get fired or dismissed or pressured out."

Harlow should know: Calvin College investigated him after he wrote an article questioning the historical Adam. His colleague and fellow theologian, John Schneider, wrote a similar article and was pressured to resign after 25 years at the college. Schneider is now beginning a research fellowship at Notre Dame.

'A Galileo Moment'

Several other well known theologians at Christian universities have been forced out; some see a parallel to a previous time when science conflicted with religious doctrine.

"The evolution controversy today is, I think, a Galileo moment," says Karl Giberson, who authored several books trying to reconcile Christianity and evolution, including The Language of Science and Faith, with Francis Collins.

Giberson — who taught physics at Eastern Nazarene College until his views became too uncomfortable in Christian academia — says Protestants who question Adam and Eve are akin to Galileo in the 1600s, who defied Catholic Church doctrine by stating that the earth revolved around the sun and not vice versa. Galileo was condemned by the church, and it took more than three centuries for the Vatican to express regret at its error.

"When you ignore science, you end up with egg on your face," Giberson says. "The Catholic Church has had an awful lot of egg on its face for centuries because of Galileo. And Protestants would do very well to look at that and to learn from it."

Abandoning Theology?


Fuzale Rana isn't so sure this is a Galileo moment: That would imply the scientists are correct. But he does believe the stakes are even higher in today's battle over evolution. It is not just about the movement of the earth, but about the nature of God and man, of sin and redemption.

"I think this is going to be a pivotal point in Church history," he says. "Because what rests at the very heart of this debate is whether or not key ideas within Christianity are ultimately true or not."

But others say Christians can no longer afford to ignore the evidence from the human genome and fossils just to maintain a literal view of Genesis.

"This stuff is unavoidable," says Dan Harlow at Calvin College. "Evangelicals have to either face up to it or they have to stick their head in the sand. And if they do that, they will lose whatever intellectual currency or respectability they have."

"If so, that's simply the price we'll have to pay," says Southern Baptist seminary's Albert Mohler. "The moment you say 'We have to abandon this theology in order to have the respect of the world,' you end up with neither biblical orthodoxy nor the respect of the world."

Mohler and others say if other Protestants want to accommodate science, fine. But they shouldn't be surprised if their faith unravels.

Defending Wishful Thinking in Science

by Jerry A. Coyne, Ph.D
[REPRINT]

On June 25 I took issue with a piece by Scientific American columnist John Horgan. Horgan attacked biological determinism on the grounds that it was both wrong (empirically and morally!) and robbed us of free will:
Biological determinism is a blight on science. It implies that the way things are is the way they must be. We have less choice in how we live our lives than we think we do. This position is wrong, both empirically and morally.
I responded that truth is truth, and that Horgan’s view that all biological determinism—including studies of evolutionary psychology—is “pseudoscientific ideology,” is simply silly. Clearly at least some of our modern behaviors—most notably sexual behavior—reflect selection pressures on our ancestors.

At any rate, Horgan has responded to my critique on his website, in a piece called “In defense of wishful thinking.“ Horgan’s defense is this: “Actually, science itself demonstrates that our hopes and fears about reality often shape it.”

He gives some examples of how “hopes and fears about reality” change our behavior:
  • The placebo effect: if patients think a pill or spray will work, even if it’s completely inert, it will work to some degree.

  • Denigrating ethnicity or gender adversely effects the performance of members of the maligned groups. Women do better on math tests when they’re told in advance that both men and women score equally well on such tests.

  • Students who believe that “wars are inevitable because human beings are naturally aggressive” tend to be less involved in disarmament and antiwar activities. (Horgan uses this result to argue against the idea that war stems from the innate aggression of males. I agree with Horgan in part, for war doesn’t necessarily reflect individual aggression, but the machinations and ambitions of politicians—and many soldiers are conscripted unwillingly.) Nevertheless, evolved male aggression is a viable hypothesis, supported by evidence that the hormones associated with human “maleness” induce aggressive behavior. It’s also a reasonable hypothesis that this connection was created by natural selection in our distant past. We may not like this, but that doesn’t falsify it a priori.

  • Denying free will has adverse consequences. As Horgan notes,
    A recent experiment shows that belief in free will has measurable consequences. The psychologists Kathleen Vohs and Jonathan Schooler asked subjects to read a passage by Francis Crick , co-discoverer of the double helix, that casts doubt on free will. Crick wrote in The Astonishing Hypothesis (Charles Schribner’s Sons, 1993) that “although we appear to have free will, in fact, our choices have already been predetermined for us and we cannot change that.” Subjects who read this passage were more likely to cheat on a test than control subjects who read a passage about brain science that did not mention free will. Mere exposure to the idea that we are not really responsible for our actions, it seems, can make us behave badly.
Note: most of these students probably conceive of free will as a “ghost in the machine,” not in the way that most compatibilist philosophers conceive of it.

To me, none of these assertions pose the slightest problem for biological determinism. Let us first dispose of the “problem” that scientific truths may sometimes induce adverse behavior. That may be the case, but empirically-determined truths do that all the time. A woman who gets proof that her spouse is cheating may poison him, but that doesn’t change the facts. We always must worry about the consequences of scientific truths, but let us not argue that things are less likely to be true because of their consequences. I know that I am going to die, and I really don’t like that truth, but it doesn’t make me deny the fact or embrace the notion of an afterlife.

More important, biological determinism reflects not just our genetic endowment, but our environments (both physical and social), and the interactions between our genes and our environments. As a biological determinist, I believe that these factors completely explain our behaviors. All of the observations mentioned above above are simply environmental interventions that affect our behaviors. That they do so is not an argument against biological determinism, any more telling than the argument that when you hit someone on the head, he becomes unconscious.

Horgan then takes up “free will” again. (I’ve previously given my notion of free will, which involves our ability to really make choices; that is, rerun a situation and you could just as well have chosen otherwise.) Horgan, however, ascribes to Dennett’s notion of free will, one that I’ve previously discussed:
(Horgan): This finding supports a sensible defense of free will mounted by the philosopher Daniel Dennett in his 2003 book Freedom Evolves (Viking Adult, 2003). Dennett argues, first, that free will is “not what tradition declares it to be: a God-like power to exempt oneself from the causal fabric of the physical world.” Free will, he contends, is an emergent property of the brain, like consciousness, that allows us to perceive, mull over and act on choices; in fact, choice, or even freedom, are reasonable synonyms for free will. Dennett calls free will “an evolved creation of human activity and beliefs” that humanity acquired recently as a consequence of language and culture as well as consciousness. Our free will grows along with our knowledge, material well-being and political freedom. Dennett’s most subtle, profound point is that free will is both an “objective phenomenon” and dependent on our belief in and perception of it.

In other words, the more we value and believe in free will, freedom and choices, the more we actually have. This is both wishful thinking and an objective, empirical truth. Wishful thinking works!
I do like Dennett’s pithy definition of “traditional” free will, but I’m not on board with either Dan’s solution or Horgan’s agreement with it. What they are saying is that the mere appearance of choice (an appearance that Dennett sees as reaching its acme, via evolution, in the complex ruminations of the human brain) is the same as “free will.” (As I remember Dan’s discussion in Freedom Evolves, he doesn’t think that any animals have free will.)

To be frank, I regard these conceptions of free will as attempts to evade the depressing fact that we really don’t make choices—that, with perhaps some quantum-induced but irrelevant exceptions—our choices have already been made before we think we’ve made them. (There is, of course, some neurological evidence for this.) Yes, if you define free will as the appearance of choice—that a woman stands before a gelato counter and appears to ruminate about which flavor she wants—and that human choice involves more complex “calculations” than that of, say, a bacterium (“Hmm. . . . I had the lemon last week. I’ll try the blackcurrant now”), then yes, we have free will. But that’s a definitional ploy, meant to keep us from thinking about the inescapable fact that such decisions are “made” long before we think we make them, and to preserve the status of humans as unique and morally responsible animals.

Horgan’s assertion that the more we think we have free will, the more free will we have, is simply wrong. We don’t have free will, at least not in the way everyone thinks we do. We are biologically determined creatures, with “biology” conceived broadly as “genes + environments + gene/environment interactions). Our brains—and therefore our choices—are as biologically determined as are our livers or kidneys. The appearance of choice is no more “real choice” than the “appearance” of a Western movie town, with its thin storefront facades buttressed from behind, is identical to a real town. Biological determinism is a fact, and Horgan should deal with it. But let no one think that biological determinism means that our behavior isn’t influenced by our environments.
