If you run out of time or can’t find the time or need more time … stop worrying:

Time might not exist, according to physicists and philosophers – but that’s okay ….. (the link is to article in The Conversation by Sam Baron)

….. developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously.

How can that be, and what would it mean? It’ll take a little while to explain, but don’t worry: even if time doesn’t exist, our lives will go on as usual.

and it gets somewhat philosophical….

…. we know we need a new physical theory to explain the universe, and that this theory might not feature time.

Suppose such a theory turns out to be correct. Would it follow that time does not exist?

It’s complicated, and it depends what we mean by exist.

and then….

There is a way out of the mess.

While physics might eliminate time, it seems to leave causation intact: the sense in which one thing can bring about another.

Perhaps what physics is telling us, then, is that causation and not time is the basic feature of our universe.

So Jesus has already come and if someone says I’m late I can reply on the grounds of a good physics hypothesis that I am not and if someone wants to book me for parking over-time I will tell the judge….

Another great program from the ABC’s Radio National, this time from the Science Friction program. The interviewer is Natasha Mitchell. This one is about 25 minutes.

Science FAIL! A perilous story of why it’s good to do

From the concluding minutes:

Dr Ben de Haas: . . . . Ideally that’s what makes the difference between science and other pursuits of truth – that we correct our errors.

Natasha Mitchell: But the current culture of science could be undermining that ideal, and is taking a toll on the mental health of early career scientists especially, — short term grants, a publish or perish culture, promotion being contingent on journal papers, job insecurity, short PhD scholarships, and a focus on only publishing positive findings.

Professor Alan Love: In recent years there have emerged movements for the publication of negative results where some journals will do that. However, it’s still clearly the case, what is expected from scientists is to break through, be the first to discover something, . . . There’s a deep tension there.  Then the only people who can secure those positions that are few and far between are the ones who “grab the golden ring” of the results that everybody wants to tweet, not the person who says, “I discovered that everything I was doing was based on an artefact.” . . . You can’t build a career on that.

artefact: something observed in a scientific investigation or experiment that is not naturally present but occurs as a result of the preparative or investigative procedure.
“the curvature of the surface is an artefact of the wide-angle view”

Mitchell: But perhaps that announcement, that everything I’ve just done for the last three years is based on an artefact, is actually the most powerful finding of all for subsequent experiments.

Love: It could be, absolutely. That’s the picture of science that we really need society to have. If they only get what they see in the movies, if they only get the sort of Era[?] stories, or the recounting of the Nobel prize lecture about how you found that amazing discovery, they’re going to really misunderstand the enterprise and why we should trust it, why we should think that it generates reliable knowledge.

If they read the front page news and they see one week, “Oh look, coffee’s good for me”, and next week, “Oh look, coffee’s bad for me” and then next week, “Oh look, coffee’s good for me again” and they become jaded if the expectation is somehow that the scientists are going to deliver some sort of inviolate factoid about coffee, can we reset those expectations? If we can, I think we can make some serious progress in how we understand the role of science in society.

And given the anti-intellectual, anti-science views that appear to be pervading very large swathes of our supposedly enlightened communities, that is surely an urgent task.

Scholarly Consensus: Some Questions Are More Important Than Others

Tags: , , ,

A few years ago, I was visiting a customer site in Denver, Colorado. Early one morning, while sitting in a cold conference room, I overheard a conversation about a guy who had recently quit. Apparently, he was the lone subject matter expert on an important project.

A: I hope he documented what he was doing. 

B: He’s pretty good about it.

A: You know what they say . . .

B: “In case you get hit by a bus”?

A: Heh-heh. Yeah.

C: We had a guy just this past year who got hit by a bus. Literally, hit by a bus.

B: He died?

C: Yeah. 

A: Oh, man.

C: You know how they tell you to look both ways, especially to the right, when you’re in India?

B: So he stepped out and didn’t see it.

C: Yeah.

B: Damn.

Double-Decker Bus

I can remember being warned about looking in the correct direction back in the military. When we sent people TDY to England, we reminded them to look both ways. If you grew up in a country where people drive on the right, you instinctively check to the left just before you step off the curb. It’s the opposite for people who grew up in left-side countries. In the split second you spend looking in the wrong direction, a vehicle can suddenly come around the corner and kill you.

This story reminds us that some decisions have more consequence than others, and some problems require an immediate decision. If you’re deciding on the color of the curtains in your living room, you may regret your choice, but it probably won’t kill you. You might even delay your choice to the point where you never get around to changing the draperies before you sell the house.

On the other hand, some questions are more pressing. Even not making a decision is still a decision. When I think of life-or-death decisions that demand a choice, I can’t help but recall the series Danger UXB. Imagine the stress of needing to make the right decision as the seconds tick away. Which wire? How does this work? Can I stop it?

I would argue that global climate disruption has become that kind of problem. Unfortunately, it stands at the convergence of science, politics, sociology, and religion. Something needs to be done immediately, the wrong choices will be deadly, and not deciding what to do about it is in itself a decision.

Some problems demand an immediate response. However, other questions — e.g.: Did Jesus exist as a historical figure? Did Josiah suppress the original Israelite pantheon, which included a mother goddess? Did the Jews of the Second Temple period ever conceive of a dying, suffering, sacrificial messiah? — do not.

From The bad news on human nature, in 10 findings from psychology by Christian Jarrett

A few excerpts:

We favour ineffective leaders with psychopathic traits. The American personality psychologist Dan McAdams recently concluded that the US President Donald Trump’s overt aggression and insults have a ‘primal appeal’, and that his ‘incendiary Tweets’ are like the ‘charging displays’ of an alpha male chimp, ‘designed to intimidate’. If McAdams’s assessment is true, it would fit into a wider pattern – the finding that psychopathic traits are more common than average among leaders. Take the survey of financial leaders in New York that found they scored highly on psychopathic traits but lower than average in emotional intelligence. A meta-analysis published this summer concluded that there is indeed a modest but significant link between higher trait psychopathy and gaining leadership positions, which is important since psychopathy also correlates with poorer leadership.

Another one of the ten says we are moral hypocrites. I know that’s true. I’m one myself. I like to think I’m a vegetarian for ethical reasons but I continue to eat fish.

This one is so depressing. I have spent most of my adult life believing in the power of education, only to learn it probably only has an effect on those who want to be better anyway.

We are blinkered and dogmatic. If people were rational and open-minded, then the straightforward way to correct someone’s false beliefs would be to present them with some relevant facts. However a classic study from 1979 showed the futility of this approach – participants who believed strongly for or against the death penalty completely ignored facts that undermined their position, actually doubling-down on their initial view. This seems co occur in part because we see opposing facts as undermining our sense of identity. It doesn’t help that many of us are overconfident about how much we understand things and that, when we believe our opinions are superior to others, this deters us from seeking out further relevant knowledge.

And do be careful not to tread on any ants from now on because they have feelings too, you know …. Bee-brained (Are insects ‘philosophical zombies’ with no inner life? Close attention to their behaviours and moods suggests otherwise).

And if you thought things really are getting worse it’s not simply concept creep either. The world really is going the way of the tediously saintly young. So says Matt Ridley whose books I once found happily enlightening.

That’s enough wallowing in misery for one weekend.

Concept Creep

Tags: , , , ,

When I hear of how Russia “attacked” the USA in the 2016 elections, and when I hear of verbal abuse being labeled a form of “violence”, and when I think a purple dot is blue because fewer blue dots have been appearing lately, then I think of “concept creep”. And then I recall how many of those of us leaving cults or other extreme fundamentalist churches were said to be experiencing the same disorder as returning soldiers with war experiences, “post traumatic stress disorder”.

From The Conversation: When Your Brain Never Runs Out of Problems….

Concepts that refer to the negative aspects of human experience and behavior have expanded their meanings so that they now encompass a much broader range of phenomena than before. This expansion takes “horizontal” and “vertical” forms: concepts extend outward to capture qualitatively new phenomena and downward to capture quantitatively less extreme phenomena. The concepts of abuse, bullying, trauma, mental disorder, addiction, and prejudice are examined to illustrate these historical changes. In each case, the concept’s boundary has stretched and its meaning has dilated. A variety of explanations for this pattern of “concept creep” are considered and its implications are explored. I contend that the expansion primarily reflects an ever-increasing sensitivity to harm, reflecting a liberal moral agenda. Its implications are ambivalent, however. Although conceptual change is inevitable and often well motivated, concept creep runs the risk of pathologizing everyday experience and encouraging a sense of virtuous but impotent victimhood.

—

Why do some social problems seem so intractable? In a series of experiments, we show that people often respond to decreases in the prevalence of a stimulus by expanding their concept of it. When blue dots became rare, participants began to see purple dots as blue; when threatening faces became rare, participants began to see neutral faces as threatening; and when unethical requests became rare, participants began to see innocuous requests as unethical. This “prevalence-induced concept change” occurred even when participants were forewarned about it and even when they were instructed and paid to resist it. Social problems may seem intractable in part because reductions in their prevalence lead people to see more of them.

Why I Am (Still) Against Nuclear Power

People on the Internet who like to style themselves as rational, worldly, and clever members of the intelligentsia enjoy poking fun at people for their irrational beliefs. The usual targets of their (our) jabs are fish in a barrel: creationism (young Earth and old Earth), homeopathy, climate-change denial, and so on.

We see, for example, groups of people dedicated to poking fun at those who are supposedly afraid of chemicals by calling water by its unfamiliar sciency name: dihydrogen monoxide. I’m not necessarily opposed to poking fun at people for their ignorance, but I can’t really support the DHMO thing, because it’s a one-joke wonder that’s too clever and far too satisfied with itself.

Punching down

There’s a sociological reason why it provokes a smug smile, but not actual laughter. It breaks one of the few rules of comedy — punching up is funny; punching down is not. We should try not to make fun of people who cannot understand science (the dumb) while we’re justifiably ridiculing those who refuse to understand science (the deliberately ignorant) or who exploit the ignorance of others for their own gain (the malicious).

Atomic Energy Town

On social media rational people enjoy posting on subjects like the anti-vaccine movement and the rejection of anthropogenic global warming. And that’s good; these are threats to human survival. However, I’ve noticed a trend in the past few years in which the proponents of the nuclear power industry have successfully made supporting “green nuclear energy” one of our merit badges.

A recent USA Today article (“People trust science. So why don’t they believe it?“) demonstrates a now-mainstream tactic: namely, juxtaposing AGW-denial with the supposed AGW solution, nuclear power.

Many conservatives reject the science of man-made climate change, just as many liberals reject the science that shows nuclear energy can safely combat it. The views we express signal which political group we belong to. The gap between what science shows and what people believe, sociologists say, is about our identity.

Do some liberals oppose nuclear power for unscientific, political reasons? Probably. Ignorance exists in all quarters. Some social liberals believe in healing crystals. Others may fear vaccines. Conservatives and liberals have irrational beliefs.

Is it safe?

The key word in the excerpt above, I suppose, is “safely.” People, we are told, have an irrational fear of nuclear power because they think it isn’t safe, which, we are further told, is ridiculous, because it’s extremely safe. And if you don’t think it’s safe, you must be a nut job. As Richard Carrier writes: Continue reading “Why I Am (Still) Against Nuclear Power”

Mega Millions tickets
Mega Millions tickets (Photo credit: Wikipedia)

Several years ago, my much-adored and much-missed mother-in-law came to visit us. This was back when we lived in Ohio. I loved her almost as much as my own mother, which is the only reason I agreed to buy her lottery tickets. She had a different, perhaps “old-world” view of the universe. Dreams could tell a person what number to play the next day. Doing certain things in a certain order might cause desired numbers to “come up.” The future was foreordained, and if you were lucky, God might drop you a hint.

As a materialist and well-documented anti-supernaturalist, of course, I consider the investment in the lotto as a tax on people who don’t understand math. With great embarrassment, I asked the clerk at the counter for the tickets. Climbing back into the car, I handed them over and said, “I hope you realize you’re the only person on Earth I’d ever do this for.” And she smiled.

I don’t recall exactly what happened after that, although I can tell you she didn’t win. Normally, when the local station showed the pick-3 and pick-4 numbers during Jeopardy!, she’d claim those were the numbers she was going to play. “Shoulda played it. Nuts. Tsk-tsk.”

Earlier, I referred to that kind of thinking as old-world. But maybe “old-school” is more apt. In any case, if you think God can affect or predict the outcome of random events — if you think he runs a rigged table — then this is the logical conclusion. God plays dice, and they’re loaded.

When James McGrath takes potshots at Mythicism or Young-Earth Creationism (YEC) (often comparing one with the other), I’m often reminded of those lottery tickets I bought over a decade ago. Was my mother-in-law right? Is my view of randomness wrong?

Take a look at what the people over at BioLogos have to say on the subject. Continue reading “How Widespread Is McGrathian Old-Earth Creationism (MOEC)?”

Grants for serious studies

Yesterday (13 February), James McGrath posted a congratulatory note to two winners of the latest Evolution & Christian Faith (ECF) grant competition. [biologos blog is undergoing reorganizing: hopefully the link (currently at http://biologos.org/blog/evolution-and-christian-faith-grantees-announced?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication)  will be restored before too long. Neil – 23rd July, 2019]. The ECF panel faced some hard choices. They fielded requests from scores of applicants, but had only about $3 million to shell out.

You’ll be happy to learn that a number of the fortunate grantees will be working on important projects related to “questions about Adam and Eve, the Fall, human identity, and Original Sin—some of the most critical interpretive issues for evangelical theology.”

BioLogos: Who are these guys?

I suppose on the face of it, nonbelievers shouldn’t care if Christians want to embrace biological evolution. In fact, it sounds like a promising idea. However, if that embrace suffocates the scientific method, then we can hardly call it a victory. Indeed, if we look at the BioLogos charter do we find science and religion viewed as a partnership of equals? Hardly.

Under the heading “What We Believe,” they state:

7. We believe that the methods of science are an important and reliable means to investigate and describe the world God has made. In this, we stand with a long tradition of Christians for whom Christian faith and science are mutually hospitable. Therefore, we reject ideologies such as Materialism and Scientism that claim science is the sole source of knowledge and truth, that science has debunked God and religion, or that the physical world constitutes the whole of reality. (emphasis added)

All right. It isn’t something I would sign onto. And I confess I get a little uncomfortable when Christians use the term Scientism, since it’s clearly an invented derogatory term that doesn’t mean much outside their echo chamber.

Science is useful, as long as it conforms to what we already “know”

But it’s their deal. So if it gets them on board, “no harm, no foul,” right? Maybe not.

Science CAN say something about the supernatural

Physicist Victor Stenger argues in HuffPo that

Scientists and science organizations are being disingenuous when they say science can say nothing about the supernatural. They know better. Their policy of appeasing religion for presumably political reasons only empowers those who are muddling education and polluting public policy with anti-scientific magical thinking.

His article is Science and Religion. I was alerted to it through Jerry Coyne’s post on Why Evolution Is True.

Stenger opens with

I find it surprising that most scientists, believers and nonbelievers alike, refuse to apply their critical thinking skills to matters of religion. . . . . Scientists prefer to follow Stephen Jay Gould’s dictum that science and religion occupy two “non-overlapping magisteria.”

That, of course, means individuals are required to leave moral and ethical questions to “scholars who interpret ancient texts.” Provocative Stenger opines that such a situation sounds to him like “Sharia law”. Moral behaviour certainly is observable and a matter of scientific understanding. (It was my own realization that all social animals have “moral codes”, including punishments meted out to those who break them, that helped me on my own journey towards atheism.)

Stenger addresses two (of several) types of scientific experiments that have been conducted to test what should be the observable effects of the supernatural on the natural world: the phenomena of answered — or unanswered — prayer and near-death experiences.

why science is not a faith

Reading the same old “tu-quoque/you too!” fallacy from fundamentalist supernaturalists that science or any position questioning the Bible is itself “a faith” or “belief” puts a responsibility however tedious, I suppose, on naturalists with a scientific disposition to continually make accessible the answer to that fatuous canard:

Tamas Pataki, from Against Religion (pp.117-118 )

The charge of scientific dogmatism is so contrary to fact and so foolish that it calls for diagnosis. Richard Dawkins is a favourite bogeyman, and McGrath and Eagleton are two of those who stalk him. How can Dawkins ‘be so sure that his current beliefs are true, when history shows a persistent pattern of the abandonment of scientific theories as better approaches emerge?’ asks McGrath. But Dawkins, of course, is not ‘so sure’: ‘My belief in evolution is not faith, because I know what it would take to change my mind, and I would gladly do so if the necessary evidence were forthcoming.’ He’s not sure (in McGrath’s sense) because although his beliefs may be indubitable in light of currently available evidence, he knows that they are not infallible. That is what science is about: conjecture (or hypothesis) and refutation.

But the religious apologists are imputing a religious conception of knowledge, characterised by inerrancy – just as the Bible is supposed to be inerrant – which allows them to stretch science on the horns of a false dilemma: either science presumes to provide incorrigible knowledge, in which case it is shamelessly dogmatic, or it is just a matter of faith, just like their turf. They have no conception of the difference between warranted but fallible belief, and faith. Finding to their satisfaction that science falls short of incorrigibility, they conclude that, after all, science and religion are in the same boat-just matters of faith.

(Pataki here footnotes by way of illustration Alister McGrath’s The Twilight of Atheism (2004), pp.93-97, 179-83. Unfortunately I have not run across a copy of McGrath’s book, so can only leave this reference here for others to follow up. But I have certainly read many of the sorts of ignorant claims Pataki refers to.)

And Anthony Grayling, from Against All Gods: Six Polemics on Religion and and an Essay on Kindness (p.34)

People who do not believe in supernatural entities do not have a ‘faith’ in ‘the non-existence of X’ (where X is ‘fairies’ or ‘goblins’ or ‘gods’); what they have is a reliance on reason and observation, and a concomitant preparedness to accept the judgement of both on the principles and theories which premise their actions. The views they take about things are proportional to the evidence supporting them, and are always subject to change in the light of new or better evidence. ‘Faith’ – specifically and precisely: the commitment to a belief in the absence of evidence supporting that belief, or even (to the greater merit of the believer) in the very teeth of evidence contrary to that belief – is a far different thing.
