10 atheist quotes that will make you question religion
From psychology to neuroscience, what we believe is not nearly as relevant as why we do.
- Belief systems arise to address the time and social conditions of each era and culture.
- Your relationship to your community and environment is very influential in what you believe.
- Neuroscience explains many of the questions as to why we believe in the first place.
When I was studying for my degree in religion, I was most fascinated by what people believe. The fact that members of the same species could invent such diverse ideas about the invisible speaks volumes about the human imagination. During that period, I recognized how essential place and time were in the formation of religious ideologies. Regardless of your belief system, we can agree that the creation of Christianity today would look nothing like the historical accounts we rely on.
It was neuroscience that stopped me from focusing on what and begin to investigate why. Why do we believe in anything metaphysical? What function do gods play in our psychology? Why do we resist the fact that we might not be right, sometimes to the point where we'll murder opposing tribes?
Environmental and genetic conditions conspire to create what we feel (or don't) about the ethereal. I get it: Many religious believers think they've got the special sauce, some hidden insight revealed only to their tribe. Yet so many conflicting ideologies cannot be right; there must be something else at play, and that thing is our unique biology.
The first few quotes below are big-picture social questions, while the remaining come from neuroscience and psychology books. They are not all atheistic per se, but they do point to the fact that humans tend to think very highly of themselves and what we believe, and that there are biological explanations for why we feel the way we do. The more we recognize that, the more likely we are to stop thinking there is only one way to discover truth.
"How much vanity must be concealed—not too effectively at that—in order to pretend that one is the personal object of a divine plan?" — Christopher Hitchens, God is not Great: How Religion Poisons Everything
Here comes logic
"Monotheism explains order, but is mystified by evil. Dualism explains evil, but is puzzled by order. There is one logical way of solving the riddle: To argue that there is a single omnipotent God who created the entire universe—and He's evil. But nobody in history has had the stomach for such a belief." — Yuval Noah Harari, Sapiens: A Brief History of Humankind
The difference is often language
"In America, belief in the unreal seems to be very fungible. Individuals don't so much abandon religious fantasy in favor of reason as find different fantasies that better suit their particular excitement and credulity quotients." — Kurt Andersen, Fantasyland: How America Went Haywire
A Buddhist approach
"Mindfulness accepts as its focus of inquiry whatever arises in one's field of awareness, no matter how disturbing or painful it might be. One neither seeks nor expects to find some greater truth lurking behind the veil of appearances. What appears and how you respond to it: that alone is what matters." — Stephen Batchelor, Confessions of a Buddhist Atheist
"Comprehension, far from being a Godlike talent from which all design must flow, is an emergent effect of systems of uncomprehending competence: natural selection on the one hand, and mindless computation on the other." — Daniel Dennett, From Bacteria to Bach and Back: The Evolution of Minds
The physical can be spiritual
"Evolution simply happened—foresightless, by chance, without goal. There is nobody to despise or rebel against—not even ourselves. And this is not some bizarre form of neurophilosophical nihilism but rather a point of intellectual honesty and great spiritual depth." — Thomas Metzinger, The Ego Tunnel: The Science of the Mind and the Myth of the Self
"Supernatural thinking is simply the natural consequence of failing to match our intuitions with the true reality of the world." — Bruce M. Hood, The Science of Superstition: How the Developing Brain Creates Supernatural Beliefs
Out of body is still in the body
"Out-of-body flight "really happens," then—it is a real physical event, but only in the patient's brain and, as a result, in his subjective experience. The out-of-body state is, by and large, an exacerbated form of the dizziness that we all experience when our vision disagrees with our vestibular system, as on a rocking boat." — Stanislas Dehaene, Consciousness and the Brain: Deciphering How the Brain Codes Our Thoughts
Randomness produces beautiful (or efficient) results
"If you let something tumble long enough, it comes out almost perfect. Such is the power of random collisions and patience, and that constitutes the sum total of nature's intelligence. All the rough edges, the flaws, the things that don't work are systematically dispatched by natural selection. What remains and carries on into the next generation and the next after that and so on are the advantageous aspects, what does work what makes survival easier. And survival is the fuel of natural selection." — Rodolfo R. Llinas, I of the vortex: From Neurons to Self
"Everything happens for a reason"
"A long line of research in cognitive science has documented that people make causal attributions about events as a means of maintaining personal control. It is the feeling that things are spinning out of control that motivates the human brain to find a pattern in events and try to predict what is going to happen next. The left-brain interpreter thus will be activated whenever the individual senses a lack of control. Superstitions and conspiracy theories can be seen as the societal consequences of the interpreter's drive to find a causal explanation for events that are seemingly out of control." — Ronald T. Kellogg, The Making of the Mind: The Nueroscience of Human Nature

Richard Feynman once asked a silly question. Two MIT students just answered it.
Here's a fun experiment to try. Go to your pantry and see if you have a box of spaghetti. If you do, take out a noodle. Grab both ends of it and bend it until it breaks in half. How many pieces did it break into? If you got two large pieces and at least one small piece you're not alone.
But science loves a good challenge<p>The mystery remained unsolved until 2005, when French scientists <a href="http://www.lmm.jussieu.fr/~audoly/" target="_blank">Basile Audoly</a> and <a href="http://www.lmm.jussieu.fr/~neukirch/" target="_blank">Sebastien Neukirch </a>won an <a href="https://www.improbable.com/ig/" target="_blank">Ig Nobel Prize</a>, an award given to scientists for real work which is of a less serious nature than the discoveries that win Nobel prizes, for finally determining why this happens. <a href="http://www.lmm.jussieu.fr/spaghetti/audoly_neukirch_fragmentation.pdf" target="_blank">Their paper describing the effect is wonderfully funny to read</a>, as it takes such a banal issue so seriously. </p><p>They demonstrated that when a rod is bent past a certain point, such as when spaghetti is snapped in half by bending it at the ends, a "snapback effect" is created. This causes energy to reverberate from the initial break to other parts of the rod, often leading to a second break elsewhere.</p><p>While this settled the issue of <em>why </em>spaghetti noodles break into three or more pieces, it didn't establish if they always had to break this way. The question of if the snapback could be regulated remained unsettled.</p>

What possible application could this have?<p>The snapback effect is not limited to uncooked pasta noodles and can be applied to rods of all sorts. The discovery of how to cleanly break them in two could be applied to future engineering projects.</p><p>Likewise, knowing how things fragment and fail is always handy to know when you're trying to build things. Carbon Nanotubes, <a href="https://bigthink.com/ideafeed/carbon-nanotube-space-elevator" target="_self">super strong cylinders often hailed as the building material of the future</a>, are also rods which can be better understood thanks to this odd experiment.</p><p>Sometimes big discoveries can be inspired by silly questions. If it hadn't been for Richard Feynman bending noodles seventy years ago, we wouldn't know what we know now about how energy is dispersed through rods and how to control their fracturing. While not all silly questions will lead to such a significant discovery, they can all help us learn.</p>
The multifaceted cerebellum is large — it's just tightly folded.
- A powerful MRI combined with modeling software results in a totally new view of the human cerebellum.
- The so-called 'little brain' is nearly 80% the size of the cerebral cortex when it's unfolded.
- This part of the brain is associated with a lot of things, and a new virtual map is suitably chaotic and complex.
Just under our brain's cortex and close to our brain stem sits the cerebellum, also known as the "little brain." It's an organ many animals have, and we're still learning what it does in humans. It's long been thought to be involved in sensory input and motor control, but recent studies suggests it also plays a role in a lot of other things, including emotion, thought, and pain. After all, about half of the brain's neurons reside there. But it's so small. Except it's not, according to a new study from San Diego State University (SDSU) published in PNAS (Proceedings of the National Academy of Sciences).
A neural crêpe
A new imaging study led by psychology professor and cognitive neuroscientist Martin Sereno of the SDSU MRI Imaging Center reveals that the cerebellum is actually an intricately folded organ that has a surface area equal in size to 78 percent of the cerebral cortex. Sereno, a pioneer in MRI brain imaging, collaborated with other experts from the U.K., Canada, and the Netherlands.
So what does it look like? Unfolded, the cerebellum is reminiscent of a crêpe, according to Sereno, about four inches wide and three feet long.
The team didn't physically unfold a cerebellum in their research. Instead, they worked with brain scans from a 9.4 Tesla MRI machine, and virtually unfolded and mapped the organ. Custom software was developed for the project, based on the open-source FreeSurfer app developed by Sereno and others. Their model allowed the scientists to unpack the virtual cerebellum down to each individual fold, or "folia."

A complicated map
Sereno tells SDSU NewsCenter that "Until now we only had crude models of what it looked like. We now have a complete map or surface representation of the cerebellum, much like cities, counties, and states."
That map is a bit surprising, too, in that regions associated with different functions are scattered across the organ in peculiar ways, unlike the cortex where it's all pretty orderly. "You get a little chunk of the lip, next to a chunk of the shoulder or face, like jumbled puzzle pieces," says Sereno. This may have to do with the fact that when the cerebellum is folded, its elements line up differently than they do when the organ is unfolded.
It seems the folded structure of the cerebellum is a configuration that facilitates access to information coming from places all over the body. Sereno says, "Now that we have the first high resolution base map of the human cerebellum, there are many possibilities for researchers to start filling in what is certain to be a complex quilt of inputs, from many different parts of the cerebral cortex in more detail than ever before."
This makes sense if the cerebellum is involved in highly complex, advanced cognitive functions, such as handling language or performing abstract reasoning as scientists suspect. "When you think of the cognition required to write a scientific paper or explain a concept," says Sereno, "you have to pull in information from many different sources. And that's just how the cerebellum is set up."
Bigger and bigger
The study also suggests that the large size of their virtual human cerebellum is likely to be related to the sheer number of tasks with which the organ is involved in the complex human brain. The macaque cerebellum that the team analyzed, for example, amounts to just 30 percent the size of the animal's cortex.
"The fact that [the cerebellum] has such a large surface area speaks to the evolution of distinctively human behaviors and cognition," says Sereno. "It has expanded so much that the folding patterns are very complex."
As the study says, "Rather than coordinating sensory signals to execute expert physical movements, parts of the cerebellum may have been extended in humans to help coordinate fictive 'conceptual movements,' such as rapidly mentally rearranging a movement plan — or, in the fullness of time, perhaps even a mathematical equation."
Sereno concludes, "The 'little brain' is quite the jack of all trades. Mapping the cerebellum will be an interesting new frontier for the next decade."
What happens if we consider welfare programs as investments?
- A recently published study suggests that some welfare programs more than pay for themselves.
- It is one of the first major reviews of welfare programs to measure so many by a single metric.
- The findings will likely inform future welfare reform and encourage debate on how to grade success.
Welfare as an investment<p>The <a href="https://scholar.harvard.edu/files/hendren/files/welfare_vnber.pdf" target="_blank">study</a>, carried out by Nathaniel Hendren and Ben Sprung-Keyser of Harvard University, reviews 133 welfare programs through a single lens. The authors measured these programs' "Marginal Value of Public Funds" (MVPF), which is defined as the ratio of the recipients' willingness to pay for a program over its cost.</p><p>A program with an MVPF of one provides precisely as much in net benefits as it costs to deliver those benefits. For an illustration, imagine a program that hands someone a dollar. If getting that dollar doesn't alter their behavior, then the MVPF of that program is one. If it discourages them from working, then the program's cost goes up, as the program causes government tax revenues to fall in addition to costing money upfront. The MVPF goes below one in this case. <br> <br> Lastly, it is possible that getting the dollar causes the recipient to further their education and get a job that pays more taxes in the future, lowering the cost of the program in the long run and raising the MVPF. The value ratio can even hit infinity when a program fully "pays for itself."</p><p> While these are only a few examples, many others exist, and they do work to show you that a high MVPF means that a program "pays for itself," a value of one indicates a program "breaks even," and a value below one shows a program costs more money than the direct cost of the benefits would suggest.</p> After determining the programs' costs using existing literature and the willingness to pay through statistical analysis, 133 programs focusing on social insurance, education and job training, tax and cash transfers, and in-kind transfers were analyzed. The results show that some programs turn a "profit" for the government, mainly when they are focused on children:
This figure shows the MVPF for a variety of polices alongside the typical age of the beneficiaries. Clearly, programs targeted at children have a higher payoff.
Nathaniel Hendren and Ben Sprung-Keyser<p>Programs like child health services and K-12 education spending have infinite MVPF values. The authors argue this is because the programs allow children to live healthier, more productive lives and earn more money, which enables them to pay more taxes later. Programs like the preschool initiatives examined don't manage to do this as well and have a lower "profit" rate despite having decent MVPF ratios.</p><p>On the other hand, things like tuition deductions for older adults don't make back the money they cost. This is likely for several reasons, not the least of which is that there is less time for the benefactor to pay the government back in taxes. Disability insurance was likewise "unprofitable," as those collecting it have a reduced need to work and pay less back in taxes. </p>
