More than two decades before Brittany Maynard’s public advocacy for death with dignity inspired lawmakers in Washington, D.C., and at least 16 states to introduce legislation authorizing the medical practice of aid in dying for the terminally ill, Senator Frank Roberts of Oregon sponsored one of the nation’s first death-with-dignity bills.

"Metaphorical thinking—our instinct not just for describing but for comprehending one thing in terms of another—shapes our view of the world, and is essential to how we communicate, learn, discover and invent. ... Our understanding of metaphor is in the midst of a metamorphosis. For centuries, metaphor has been seen as a kind of cognitive frill, a pleasant but essentially useless embellishment to 'normal' thought. Now, the frill is gone. New research in the social and cognitive sciences makes it increasingly plain that metaphorical thinking influences our attitudes, beliefs, and actions in surprising, hidden, and often oddball ways." Geary further unpacks metaphor's influence in his foreword: "Metaphor conditions our interpretations of the stock market and, through advertising, it surreptitiously infiltrates our purchasing decisions. In the mouths of politicians, metaphor subtly nudges public opinion; in the minds of businesspeople, it spurs creativity and innovation. In science, metaphor is the preferred nomenclature for new theories and new discoveries; in psychology, it is the natural language of human relationships and emotions."

The upshot of the boom in metaphor studies, Geary makes clear, is the overturning of that presumption toward literalism: Nowadays, it's believers in a literalism that goes all the way down (so to speak) who are on the defensive in intellectual life, and explorers of metaphor who are on the ascendant. As a result, Geary hardly feels a need to address literalism, devoting most of his book to how metaphor connects to etymology, money, mind, politics, pleasure, science, children, the brain, the body, and such literary forms as the proverb and aphorism.

According to a new report by Calvin College assistant professor Jonathan Hill, many Americans do not think it's that important to have the "correct beliefs" on the origins of human life.

"No creationist wakes up in the morning and says, 'I have really strong opinions about whether Archaeopteryx is the ancestor of modern birds,'" he said.* "Who are we as people? That’s the question that they think evolution is answering. What does it mean to be a person? What does it mean to be an animal?"

What that means is that "debates" about evolution and creationism actually might not be that effective

LYING may be an age-old part of politics, but it’s becoming easier to spot the fibs, fictions and falsehoods. A growing army of fact-checkers around the world is busy debunking falsehoods from presidents, prime ministers and pundits — and if their results are indicative, 2014 was a banner year. Some of the claims were so absurd that fact-checking groups honored them with awards, like Australia’s Golden Zombie and Italy’s Insane Whopper of the Year.Such lies are fun to read, but identifying them is serious business: Misinformation, unchecked, can turn elections, undermine public health efforts and even lead countries into war.

It seems we may all be vulnerable to moral illusions the ethical equivalent of the bending lines that trick the eye on cereal boxes and in psychology textbooks. Illusions are a favorite tool of perception scientists for exposing the workings of the five senses, and of philosophers for shaking people out of the naïve belief that our minds give us a transparent window onto the world (since if our eyes can be fooled by an illusion, why should we trust them at other times?). Today, a new field is using illusions to unmask a sixth sense, the moral sense.

The first hallmark of moralization is that the rules it invokes are felt to be universal. Prohibitions of rape and murder, for example, are felt not to be matters of local custom but to be universally and objectively warranted. One can easily say, “I don’t like brussels sprouts, but I don’t care if you eat them,” but no one would say, “I don’t like killing, but I don’t care if you murder someone.”The other hallmark is that people feel that those who commit immoral acts deserve to be punished.

Until recently, it was understood that some people didn’t enjoy smoking or avoided it because it was hazardous to their health. But with the discovery of the harmful effects of secondhand smoke, smoking is now treated as immoral. Smokers are ostracized; images of people smoking are censored; and entities touched by smoke are felt to be contaminated (so hotels have not only nonsmoking rooms but nonsmoking floors). The desire for retribution has been visited on tobacco companies, who have been slapped with staggering “punitive damages.” At the same time, many behaviors have been amoralized, switched from moral failings to lifestyle choices.

Which religion will have the toughest time reconciling aliens with its beliefs?

Which religions are more open to the idea of alien life?

Let’s say you discover some aliens on some other planets and you decide that you should convert them to Christianity. A reasonable question should be why? If they live on planet Earth, they could be descendants of Adam and Eve but if they are Klingons living on planet whatever, they couldn’t suffer from original sin because they’re not descendants of Adam and Eve. Christianity would make no sense for these creatures, unless our understanding of original sin makes no sense.

Students who learned that great scientists struggled, both personally and intellectually, outperformed those who learned only of the scientists’ great achievements, new research shows.

A team of researchers walked every street in 228 census tracts around Los Angeles and New Orleans and recorded every outdoor ad they saw. Another group surveyed 2,881 residents of the same census tracts by telephone, paying them to report their height, weight and other information. After analyzing this hard-won data, the authors conclude: “For every 10 percent increase in food advertisements, the odds of being obese increased by 5 percent.” That is, areas with more outdoor food ads have a higher proportion of obese people than ones with fewer ads.

The problem is that their policy recommendations rest on a crucial but unjustified assumption: that any link between obesity and advertising occurs because more advertising causes higher rates of obesity. But the study at hand showed only an association: people living in areas with more food ads were more likely to be obese than people living in areas with fewer food ads. To be fair, the researchers correctly note that additional steps would be needed to prove that food ads cause obesity. But until those steps are taken, talk of restricting ads is premature. In fact, it is easy to imagine how the causation could run the opposite way (something the article did not mention): If food vendors believe obese people are more likely than non-obese people to buy their products, they will place more ads in areas where obese people already live. Suppose we counted ads for fitness-oriented products like bicycles and bottled water, and found more of those ads in places with less obesity. Would it then be wise anti-obesity policy to subsidize such ads? Or would the smarter conclusion be that the fitness companies suspect that the obese are less likely than the fit to buy their products?

When we seek to base policy on evidence, we must remember that not all “evidence” is created equal. Taken at face value, the study on ads and obesity provides some indication that the two are linked, but no evidence that food ads cause obesity. The fact that the causal conclusion may coincide with a moral belief — that it is wrong to tempt people who overeat by showing them ads for food — does not make it valid.

The Danish Medical Association said it had considered suggesting a legal ban on the procedure for children under the age of 18, because it believed circumcision should be “an informed, personal choice” that young men make for themselves.ADVERTISINGinRead invented by Teads When parents have their sons circumcised, it robs boys of the ability to make decisions about their own bodies, and choose their cultural and religious beliefs for themselves, the organisation said.

As the doctor Mark Tonelli has argued, distinct forms of knowledge can’t be judged by the same standards: what a patient prefers on the basis of personal experience; what a doctor thinks on the basis of clinical experience; and what clinical research has discovered — each of these is valuable in its own way. While scientists concur that randomized trials are ideal for evaluating the average effects of treatments, such precision isn’t necessary when the benefits are obvious or clear from other data.

Distrusting expertise makes it easy to confuse an absence of randomized evaluations with an absence of knowledge. And this leads to the false belief that knowledge of what works in social policy, education or fighting terrorism can come only from randomized evaluations. But by that logic (as a spoof scientific article claimed), we don’t know if parachutes really work because we have no randomized controlled trials of them.

Experiments, of course, are invaluable and have, in the past, shown the consensus opinion of experts to be wrong. But those who fetishize this methodology, as the flossing example shows, can also impair progress toward the truth. A strong demand for evidence is a good thing. But nurturing a more nuanced view of expertise should be part of that demand.
