Atheism is inconsistent with science, says Dartmouth physicist Marcelo Gleiser
Is it saying to much to say somthing doesn't exist when you have no evidence either way?
- Dr. Marcelo Gleiser has become the first Latin American to win the Templeton Prize.
- The prize is given out for "contribution to affirming life's spiritual dimension."
- In an interview about the prize, he argued that atheism is "inconsistant with the scientific method."
Dartmouth College physics professor Marcelo Gleiser has become the first Latin American to win the Templeton Prize in recognition of his "exceptional contribution to affirming life's spiritual dimension, whether through insight, discovery, or practical works."
Prior to winning the 2019 award on March 19, Dr. Gleiser had exhibited his spiritual side to the press, even arguing why he believes atheism is unscientific.
Why saying “God doesn’t exist” is saying too much
In an interview that will shock many atheists, Dr. Gleiser told Scientific American why he finds atheism to be a bridge too far for a scientific mind:
"I think atheism is inconsistent with the scientific method. What I mean by that is, what is atheism? It's a statement, a categorical statement that expresses belief in nonbelief. 'I don't believe even though I have no evidence for or against, simply I don't believe.' Period. It's a declaration. But in science we don't really do declarations. We say, 'Okay, you can have a hypothesis, you have to have some evidence against or for that.' And so an agnostic would say, look, I have no evidence for God or any kind of god (What god, first of all? The Maori gods, or the Jewish or Christian or Muslim God? Which god is that?) But on the other hand, an agnostic would acknowledge no right to make a final statement about something he or she doesn't know about."
He further explains his stance on not trying to claim that we know everything in a well-reasoned defense of humility in science:
"I believe we should take a much humbler approach to knowledge, in the sense that if you look carefully at the way science works, you'll see that yes, it is wonderful — magnificent! — but it has limits. And we have to understand and respect those limits. And by doing that, by understanding how science advances, science really becomes a deeply spiritual conversation with the mysterious, about all the things we don't know."
Is this line of thinking scientifically useful?
In some ways, it is.
Dr. Gleiser reminds us that we are on an "island of knowledge" in the middle of an "ocean of the unknown." As knowledge advances, we become more aware of what we don't know. As he puts it:
The paradox of knowledge is that as it expands and the boundary between the known and the unknown changes, you inevitably start to ask questions that you couldn't even ask before.
His notion that we should not be too proud of what we know and open to the idea that we might discover something tomorrow that changes everything isn't without precedent. Lord Kelvin, a brilliant British scientist of the 19th century, claimed that flight was impossible and that X-rays were a hoax. Albert Abraham Michelson, an American physicist also working just before the relativistic and quantum revolutions in physics, suggested that the laws of physics had all been worked out and that the only task left was to improve accuracy in measurement.
If we listened to these two who thought we'd already figured everything out, we'd be stuck in the 1890s. It may well turn out that the claim "there is no God" could end up being similar to saying, "No balloon and no aeroplane will ever be practically successful" in 1902. Similarly, skepticism of the claim "X doesn't exist" is also important in science since "X" might show up someday.
Russell and Sagan on why he can chill out
While it remains true that humility can be a good thing, that we don't know what we don't know, and that it is impossible to prove the negative statement that "God doesn't exist" Bertrand Russell reminds us that we can still be rational while saying we don't believe in something we cannot disprove the existence of.
Famous for his well-reasoned atheism, Russell acknowledged that he was technically an agnostic and declaring there to be no God was a step too far. However, he pointed out why that step shouldn't bother anybody:
"I ought to call myself an agnostic; but, for all practical purposes, I am an atheist. I do not think the existence of the Christian God any more probable than the existence of the gods of Olympus or Valhalla. To take another illustration: nobody can prove that there is not between the Earth and Mars a china teapot revolving in an elliptical orbit, but nobody thinks this sufficiently likely to be taken into account in practice. I think the Christian God just as unlikely."
That quote refers to his famous teapot analogy, excerpted below:
"If I were to suggest that between the Earth and Mars there is a china teapot revolving about the sun in an elliptical orbit, nobody would be able to disprove my assertion provided I were careful to add that the teapot is too small to be revealed even by our most powerful telescopes. But if I were to go on to say that, since my assertion cannot be disproved, it is intolerable presumption on the part of human reason to doubt it, I should rightly be thought to be talking nonsense."
What Russell is saying is that just because a point that is asserted without evidence cannot be disproved doesn't mean it is unreasonable to think it isn't true. Furthermore, Russell places the burden of proof on the person making the positive claim — God/the teapot exists — and not on the person questioning that claim.
Astronomer and science educator Carl Sagan made a similar point about the dragon in his garage:
"Suppose I seriously make such an assertion to you. Surely you'd want to check it out, see for yourself. There have been innumerable stories of dragons over the centuries, but no real evidence. What an opportunity!
'Show me,' you say. I lead you to my garage. You look inside and see a ladder, empty paint cans, an old tricycle--but no dragon.
'Where's the dragon?' you ask.
'Oh, she's right here,' I reply, waving vaguely. 'I neglected to mention that she's an invisible dragon.'
You propose spreading flour on the floor of the garage to capture the dragon's footprints.
'Good idea,' I say, 'but this dragon floats in the air.'
Then you'll use an infrared sensor to detect the invisible fire.
'Good idea, but the invisible fire is also heatless.'
You'll spray-paint the dragon and make her visible.
'Good idea, but she's an incorporeal dragon and the paint won't stick.'
And so on. I counter every physical test you propose with a special explanation of why it won't work.
Now, what's the difference between an invisible, incorporeal, floating dragon who spits heatless fire and no dragon at all? If there's no way to disprove my contention, no conceivable experiment that would count against it, what does it mean to say that my dragon exists? Your inability to invalidate my hypothesis is not at all the same thing as proving it true. Claims that cannot be tested, assertions immune to disproof are veridically worthless, whatever value they may have in inspiring us or in exciting our sense of wonder. What I'm asking you to do comes down to believing, in the absence of evidence, on my say-so."
Sagan, like Russell, is arguing that the burden of proof is on the person making the claim. Since there is no evidence of the dragon, it is hardly anti-scientific to say you don't believe the dragon is there.
Is it going too far to claim that God doesn't exist? That depends on where you want to place the burden of proof and how much evidence (or the lack thereof) is needed to make a claim. In any case, Dr. Gleiser makes a good point about not claiming to know more than you do and the need for a bit of humility.
I for one still won't believe you if you tell me you're off for a cup of tea on Mars with the dragon that lives in your garage.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Great ideas in philosophy often come in dense packages. Then there is where the work of Marcus Aurelius.
- Meditations is a collection of the philosophical ideas of the Roman Emperor Marcus Aurelius.
- Written as a series of notes to himself, the book is much more readable than the dry philosophy most people are used to.
- The advice he gave to himself 2,000 years ago is increasingly applicable in our hectic, stressed-out lives.
Can dirt help us fight off stress? Groundbreaking new research shows how.
- New research identifies a bacterium that helps block anxiety.
- Scientists say this can lead to drugs for first responders and soldiers, preventing PTSD and other mental issues.
- The finding builds on the hygiene hypothesis, first proposed in 1989.
Are modern societies trying too hard to be clean, at the detriment to public health? Scientists discovered that a microorganism living in dirt can actually be good for us, potentially helping the body to fight off stress. Harnessing its powers can lead to a "stress vaccine".
Researchers at the University of Colorado Boulder found that the fatty 10(Z)-hexadecenoic acid from the soil-residing bacterium Mycobacterium vaccae aids immune cells in blocking pathways that increase inflammation and the ability to combat stress.
The study's senior author and Integrative Physiology Professor Christopher Lowry described this fat as "one of the main ingredients" in the "special sauce" that causes the beneficial effects of the bacterium.
The finding goes hand in hand with the "hygiene hypothesis," initially proposed in 1989 by the British scientist David Strachan. He maintained that our generally sterile modern world prevents children from being exposed to certain microorganisms, resulting in compromised immune systems and greater incidences of asthma and allergies.
Contemporary research fine-tuned the hypothesis, finding that not interacting with so-called "old friends" or helpful microbes in the soil and the environment, rather than the ones that cause illnesses, is what's detrimental. In particular, our mental health could be at stake.
"The idea is that as humans have moved away from farms and an agricultural or hunter-gatherer existence into cities, we have lost contact with organisms that served to regulate our immune system and suppress inappropriate inflammation," explained Lowry. "That has put us at higher risk for inflammatory disease and stress-related psychiatric disorders."
University of Colorado Boulder
This is not the first study on the subject from Lowry, who published previous work showing the connection between being exposed to healthy bacteria and mental health. He found that being raised with animals and dust in a rural environment helps children develop more stress-proof immune systems. Such kids were also likely to be less at risk for mental illnesses than people living in the city without pets.
Lowry's other work also pointed out that the soil-based bacterium Mycobacterium vaccae acts like an antidepressant when injected into rodents. It alters their behavior and has lasting anti-inflammatory effects on the brain, according to the press release from the University of Colorado Boulder. Prolonged inflammation can lead to such stress-related disorders as PTSD.
The new study from Lowry and his team identified why that worked by pinpointing the specific fatty acid responsible. They showed that when the 10(Z)-hexadecenoic acid gets into cells, it works like a lock, attaching itself to the peroxisome proliferator-activated receptor (PPAR). This allows it to block a number of key pathways responsible for inflammation. Pre-treating the cells with the acid (or lipid) made them withstand inflammation better.
Lowry thinks this understanding can lead to creating a "stress vaccine" that can be given to people in high-stress jobs, like first responders or soldiers. The vaccine can prevent the psychological effects of stress.
What's more, this friendly bacterium is not the only potentially helpful organism we can find in soil.
"This is just one strain of one species of one type of bacterium that is found in the soil but there are millions of other strains in soils," said Lowry. "We are just beginning to see the tip of the iceberg in terms of identifying the mechanisms through which they have evolved to keep us healthy. It should inspire awe in all of us."
