Rewriting Earth's Creation Story “We as a scientific community created an origin myth that has no more intellectual value than Genesis.”

From the Atlantic

...Ever since Apollo astronauts toted chunks of the moon back home, the story has sounded something like this: After coalescing from grains of dust that swirled around the newly ignited sun, the still-cooling Earth would have been covered in seas of magma, punctured by inky volcanoes spewing sulfur and liquid rock. The young planet was showered in asteroids and larger structures called planetisimals, one of which sheared off a portion of Earth and formed the moon. Just as things were finally settling down, about a half-billion years after the solar system formed, the Earth and moon were again bombarded by asteroids whose onslaught might have liquefied the young planet—and sterilized it.

Geologists named this epoch the Hadean, after the Greek version of the underworld. Only after the so-called Late Heavy Bombardment quieted some 3.9 billion years ago did Earth finally start to morph into the Edenic, cloud-covered, watery world we know.But as it turns out, the Hadean may not have been so hellish. New analysis of Earth and moon rocks suggest that instead of a roiling ball of lava, baby Earth was a world with continents, oceans of water, and maybe even an atmosphere. It might not have been bombarded by asteroids at all, or at least not in the large quantities scientists originally thought. The Hadean might have been downright hospitable, raising questions about how long ago life could have arisen on this planet.

“Although, if you go back to the original Greek Hell, Hades, you had to cross a river. It’s a cool, wet place. So maybe the joke is on us,” says Mark Harrison, a geologist at the University of California at Los Angeles...

...“So maybe the Hadean was not so Hades-like,” Reimink says.

Wadhwa says lunar samples and zircon samples are so limited that we still can’t paint a full picture of the Earth’s turbulent early days. In one sense, everyone might be a little bit right. Earth might have been nice and calm in the time between major impacts. Or some areas might have been molten, while some areas might have been solid and covered in oceans, she says.
One thing is clear, however: Harrison says there has never been any evidence to support the canonical hellish vision of magma lakes and tar-colored volcanos showered in fiery meteors.

“There is absolutely not a single scrap of observational evidence that requires that scenario ever took place. We as a scientific community created an origin myth that has no more intellectual value than 1 Genesis,” Harrison says. “Although we’re very quick to criticize those that operate on faith, that’s exactly what we did.”

Theology of glory vs theology of the cross ... in the ratings

"...To use another TV analogy, given the choice between the life of Mad Men‘s Don Draper (glamorous, wealthy, powerful, ascendant) and FNL‘s Eric Taylor (gritty, financially tenuous, scrutinized, downwardly mobile), most of us would choose Draper’s. But given the choice of which man we would rather be, the tables turn (ht RJH). Draper is defined by deceit, self-hatred, cold-hearted manipulation and loneliness, while Taylor is fiercely loved, has a strong backbone (and knows how to use it), genuine self-respect and is capable of meaningful relationships with others. He is the happier and healthier person, by far. The kicker here (pun intended) is that, as human beings/sinners, we are instinctually drawn to a theology of glory – to cast ourselves as the hero of our particular story, the master of our domain, if you will. We want to believe that we’re on the side of the angels, that if we dig deep enough, we can summon what we need to triumph. We don’t like stories about pain or defeat, however touching/honest they may be – we tolerate suffering only to the degree that it pays off – we want our Easter sans Good Friday, thank you very much. The urge is to see through our Calvary, rather than take it for what it is: a death. 
The theology of glory will trump the theology of the cross every time… in the ratings..."

Morality Binds and Blinds

From Jonathan Haidt's The Righteous Mind
Morality binds and blinds. This is not just something that happens to people on the other side. We all get sucked into tribal moral communities. We circle around sacred values and then share post hoc arguments about why we are so right and they are so wrong. We think the other side is blind to truth, reason, science, and common sense, but in fact everyone goes blind when talking about their sacred objects… If you want to understand another group, follow the sacredness.”

Why Sam Harris is Unlikely to Change his Mind - Jonathan Haidt

From Jonathan Haidt and the rest here from the Evolution Institute

The New Atheist Sam Harris recently offered to pay $10,000 to anyone who can disprove his arguments about morality. Jonathan Haidt analyzes the nature of reasoning, and the ease with which reason becomes a servant of the passions. He bets $10,000 that Harris will not change his mind. 
Reason has long been worshipped by philosophers and intellectuals. In Plato’s dialogue Timaeus, the gods created humankind with a soul of perfect rationality and inserted it into our spherical heads, which were “the most divine part of us and the lord of all that is in us.” (The Gods then realized that they had to create necks, to keep reason insulated from the seething passions of the rest of the body.) During the “age of reason,” the French revolutionaries pulled the Christs and crucifixes out of the cathedrals and replaced them with images of reason. And in our own time, the New Atheists have written books and started foundations urging people to fight religion with reason.
The New Atheist Sam Harris has even gone so far as to argue, in his book The Moral Landscape, that reason and science can tell us what is right and wrong. Morality is—in his definition—limited to questions about “the well-being of conscious creatures.” Well-being can be measured objectively, he says, by methods such as fMRI scans. Therefore, whatever practices, customs, and ways of living maximize those measurements are morally correct; others are morally wrong. He does not say that there is a single best society (hence the image of a landscape, with multiple peaks). But he claims that moral values are facts, no different from the kinds of facts discovered by chemists. Scientific methods give correct answer to questions in chemistry, and they can therefore do so for morality as well. Harris’s confidence in his reasoned argument is so strong that he has issued The Moral Landscape Challenge: He will personally pay $10,000 to anyone who submits an essay so logically compelling that it makes him change his mind and renounce his views. (The contest closes February 9.) 
Critics of religion are right that science has a long track record of undermining claims about God’s role in the material world. Miracles don’t seem to occur as frequently as they used to. But the funny thing is that in the last 40 years, science has also undermined claims about the role and reliability of reason in our daily lives. In the 1960s, psychologists began studying the mind as a kind of computer. But in the 1970s, Daniel Kahneman and Amos Tversky began documenting the many bugs, or intuitive biases, in the software. For example, people are more likely to choose a surgical procedure when the outcome is framed in terms of the odds of survival, rather than the (equivalent) odds of death...
...In the 2000s, in my own area of research—moral judgment—it became clear that people make judgments of right and wrong almost instantly, and then make up supporting reasons later. The intuitive dog wags its rational tail, which explains why it is so difficult to change anyone’s mind on a moral issue by refuting every reason they offer. To sum it all up, David Hume was right in 1739 when he wrote that reason was “the slave of the passions,” rather than the divine master, or charioteer, as Plato had believed. 
I’m not saying that we can’t reason quite well about many unemotional situations where we really want to know the right answer, such as whether it is better to drive or take the train to the airport, given current traffic conditions. But when we look at conscious verbal reasoning as an evolutionary adaptation, it begins to look more like a tool for helping people argue, persuade, and guard their reputations than a tool shaped by selection pressures for finding objective truth. Hugo Mercier and Dan Sperber synthesized the large bodies of research on reasoning in cognitive and social psychology like this: “The function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade…. Skilled arguers are not after the truth but after arguments supporting their views.” When self-interest, partisan identity, or strong emotions are involved, reasoning turns into a lawyer, using all its powers to reach the desired conclusion... 
...If reasoning is so easily swayed by passions, then what kind of reasoning should we expect from people who hate religion and love reason? Open-minded, scientific thinking that tries to weigh the evidence on all sides? Or standard lawyerly reasoning that strives to reach a pre-ordained conclusion? When I was doing the research for The Righteous Mind, I read the New Atheist books carefully, and I noticed that several of them sounded angry. I also noticed that they used rhetorical structures suggesting certainty far more often than I was used to in scientific writing – words such as “always” and “never,” as well as phrases such as “there is no doubt that…” and “clearly we must…” 
To check my hunch, I took the full text of the three most important New Atheist books—Richard Dawkins’ The God Delusion, Sam Harris’s The End of Faith, and Daniel Dennett’s Breaking the Spell and I ran the files through a widely used text analysis program that counts words that have been shown to indicate certainty, including “always,” “never,” “certainly,” “every,” and “undeniable.” To provide a close standard of comparison, I also analyzed three recent books by other scientists who write about religion but are not considered New Atheists: Jesse Bering’s The Belief Instinct, Ara Norenzayan’s Big Gods, and my own book The Righteous Mind...


...Reason is indeed crucial for good public policy and a good society. But isn’t the most reasonable approach one that takes seriously the known flaws of human reasoning and tries to work around them? Individuals can’t be trusted to reason well when passions come into play, yet good reasoning can sometimes emerge from groups. This is why science works so well. Scientists suffer from the confirmation bias like everybody else, but the genius of science as an institution is that it incentivizes scientists to disconfirm each others’ ideas, and it creates a community within which a reasoned consensus eventually emerges.
 
I agree with Harris that the historical shift away from revealed religion as the basis of society and toward democracy, individual rights, reason, and science as foundations of moral and political authority has been overwhelmingly good for people in Western societies. I am not anti-reason. I am also not anti-religion. I am opposed to dogmatism. I am skeptical of each person’s individual powers of reasoning, and I’m even more skeptical of the reasoning of groups of activists, hyper-partisans, and other righteous reformers who would remake society according to their own reasoned (or revealed) vision... 
...If we want to improve our politics and our society, let’s be reasonable about reason and its limitations. Of course, I have used my powers of reasoning (and intuition) to write this essay, and I have drawn on scientific studies to back up my claim that Harris is unlikely to change his mind and renounce his claims about morality. But people are complicated and it’s always hazardous to use scientific studies to predict the behavior of an individual. I could well be wrong.
Sam Harris's fair response can also be found here where he addresses the findings of "certainty" words and when he did change his mind.

Let's condemn religion...?

Condemn religion

"All major religions are equally valid and basically teach the same thing."To assert that the doctrinal differences between religions are insignificant is itself a doctrine, and one that is indefensible.
"Each religion sees part of spiritual truth, but none can see the whole truth. "From what absolute vantage point can you claim to relativize the absolute claims of the different scriptures?
"Religious belief is too culturally and historically conditioned to be 'truth'"If you say "no belief can be held as universally true for everyone", then by your own rules you can't say that this statement is universally true.
"It is arrogant to insist your religion is right and to convert others to it."If you say "all religious claims to have a better view of things are arrogant and wrong", then by your own rules that statement is arrogant and wrong.

Peter Hitchens (the late Christopher Hitchens Brother) on why he wrote The Rage Against God

"I want to explain how I became convinced, by reason and experience, of the necessity and rightness of a form of Christianity that is modest, accommodating and thoughtful - but ultimately uncompromising about its vital truth. I hope very much that by doing so I can at least cause those who consider themselves to be atheists to hesitate over their choice. I also hope to provide Christian readers with insights they can use the better to understand their unbelieving friends, and so perhaps to sow some small seeds of doubt in the minds of those friends."

Barack Obama on different points of view

I don’t agree that you, when you become students at colleges, have to be coddled and protected from different points of view. I think you should be able to — anybody who comes to speak to you and you disagree with, you should have an argument with ‘em. But you shouldn’t silence them by saying, “You can’t come because I’m too sensitive to hear what you have to say.” That’s not the way we learn either.

California's State Religion

From and the rest at the Orange County Register 
In a state ruled by a former Jesuit, perhaps we should not be shocked to find ourselves in the grip of an incipient state religion. Of course, this religion is not actually Christianity, or even anything close to the dogma of Catholicism, but something that increasingly resembles the former Soviet Union, or present-day Iran and Saudi Arabia, than the supposed world center of free, untrammeled expression. 
Two pieces of legislation introduced in the Legislature last session, but not yet enacted, show the power of the new religion. One is Senate Bill 1146, which seeks to limit the historically broad exemptions the state and federal governments have provided religious schools to, well, be religious. 
Under the rubric of official “tolerance,” the bill would only allow religiously focused schools to deviate from the secular orthodoxy required at nonreligious schools, including support for transgender bathrooms or limitations on expressions of faith by students and even Christian university presidents, in a much narrower range of educational activity than ever before. Many schools believe the bill would needlesslyrisk their mission and funding to “solve” gender and social equity problems on their campuses that currently don’t exist... 
...For the record, I am neither a Christian, nor do I deny that climate change could pose a potential serious long-term threat to humanity. What worries me most is the idea that one must embrace official orthodoxy about how to combat this phenomenon, or question its priority over so many other pressing concerns, such as alleviating poverty, both here and abroad, protecting the oceans or a host of other issues. Similarly, I have always disagreed with holy rollers like Sen. Ted Cruz, who would seek to limit, for example, abortion or the rights of gay people to marry, or would allow school prayer. 
But the new progressive intolerance now represents, in many ways, as great, if not more pervasive, a threat to the republic than that posed by either religious fundamentalists or even the most fervent climate change denier. It violates the Madisonian principle that assumed that religious and moral ideas “must be left to the conviction and conscience of every man; and it is the right of every man to exercise it as these may dictate.” To revoke that principle is to reduce the United States to just another authoritarian state, even if the official ideology is couched in scientific research or estimable embrace of racial or gender differences... 
...Ultimately, we as Americans – and Californians – will pay a price for this. History is replete with stories of decline brought on by enforced official orthodoxy, from Byzantium to China’s Qing dynasty, the Spain of the Inquisition, Nazi Germany, the Soviet Union or the current religious autocracies of the contemporary Middle East. As we seek to limit options and ways of thought about everything from marriage and bathrooms to how the planet operates, we don’t just persecute dissenters. We also undermine our ability to innovate, adapt and evolve as a society.

Neil deGrasse Tyson thinks there's a 'very high' chance the universe is just a simulation

We trust the scientists around us to have the best grasp on how the world actually works.
So at this year's 2016 Isaac Asimov Memorial Debate at the American Museum of Natural History, which addressed the question of whether the universe is a simulation, the answers from some panelists may be more comforting than the responses from others.
Physicist Lisa Randall, for example, said she thought the odds that the universe isn't "real" are so low as to be "effectively zero."
A satisfying answer for those who don't want to sit there puzzling out what it would mean for the universe not to be real, to be sure.
But on the other hand, astrophysicist Neil deGrasse Tyson, who was hosting the debate, said that he thinks the likelihood of the universe being a simulation "may be very high."

Tyson points out that we humans have always defined ourselves as the smartest beings alive, orders of magnitude more intelligent than species like chimpanzees that share close to 99%of our DNA. We can create symphonies and do trigonometry and astrophysics (some of us, anyway).
But Tyson uses a thought experiment to imagine a life-form that's as much smarter than us as we are than dogs, chimps, or other terrestrial mammals.
"What would we look like to them? We would be drooling, blithering idiots in their presence," he says.
Whatever that being is, it very well might be able to create a simulation of a universe.

No such thing as a Philosophy-Free Science?

Scientists sometimes deceive themselves into thinking that philosophical ideas are only, at best, decorations or parasitic commentaries on the hard, objective triumphs of science, and that they themselves are immune to the confusions that philosophers devote their lives to dissolving. But there is no such thing as philosophy-free science, there is only science whose philosophical baggage is taken on board without examination.

Thoughts on the Thoughts and Prayer Issue, and on "foundational and tradition-dependent assumptions"

From and the rest at CNN
"...America is deeply divided along the transcendence line. Tens of millions of Americans profess belief in a transcendent God. They include Christians, Jews, Muslims and people of many other faiths. Yet these generic labels are also imprecise; many self-identifying Christians and Jews reject the idea that God intervenes in the world in miraculous and supernatural ways.  
They may participate in religious practices. They may even pray. But they do not believe that prayer "works." They do not have a category of "forgiveness" that appeals to transcendent justice and mercy.  
They do not anticipate a transcendent world to come. Each of them lives out a kind of faith, but the content and contours of that faith is focused on the present physical world and the people in it. 
The transcendence line is not the difference between "belief" and "unbelief." Each of us lives according to strongly held commitments and values-infused beliefs. The liberal atheist who stands up for "equality" and "dignity" relies on foundational and tradition-dependent assumptions in much the same way as the religious conservative who defends "morality" and "truth."
