Putting the Humanity Back in Economics

So Professor Jacob Stoll defends the study of the humanities with the thought that all the great economic thinkers from Aristotle to Locke to Adam Smith to Karl Marx to Lord Keynes and so forth and so on have been primarily "humanists."  They thought of economic thinking as a part of thinking about the whole human being and the whole human good.  It was a part that couldn't really be separated from the whole.  So separating economics from politics and philosophy didn't occur to them to be either desirable or possible.  As Professor Stoll explains:


[T]he greatest revolution in economics in the past 50 years involves not only the transformation of the discipline into a more quantitative science but also the separation of the business curriculum from the humanities. Training in economics at the college level no longer forces students to think of people as moral agents shaped by religion, culture, and society, but rather as one-dimensional rational actors blindly pursuing material self-interest. Even behavioral economics, which challenges the rational-actor theory, makes universal claims about human psychology without the deep context of history and culture. (Can there truly be universal or biologically motivated shopping habits or attitudes toward consumerism?)

Now there's something to be said for thinking of human beings, for instructional or experimetnal purposes, as "one-dimensional rational actors blindly pursuing material self-interest," as long as you don't forget that your not thinking about whole, real people.  The philosophers Thomas Hobbes and John Locke even said that human beings would be better off if they more consistently understood their relationships with others in terms of consent and contract in the service of self-interest.  For them, the doctrine of self-interest rightly understood was, in part, reformist or enlightenment propaganda.  It was propaganda that did some good in making the world more prosperous and free, even as had its downsides when it came to moral agency or purposefulness, religion, culture, and philosophy.

But those more "humanistic"—meaning philosophically educated and concerned—economic thinkers of the past were aware of the limits of that kind of explanation, just as they were aware that arguments for so-called "rational choice" are, in part, a kind of liberal (we now say libertarian) propaganda.

What's wrong with economists who only know their technical discipline and no more is they easily forget that limits of what they can explain.  And they easily become dogmatists in the thrall of a combination of scientism (or going beyond scientific knowledge in the direction of ideology) and advocacy.  They really think that they can explain everything through self-interest or demand or whatever, because they haven't learned enough—or studied widely and deeply enough—to know otherwise.

Professor Stoll is also right that when rational-choice is rejected as an unrealistic abstraction, it tends to be replaced by the new forms of scientism of behavioral economics—ones that go in the other direction of abstracting from the real capacity of reason to manage human affairs.

The problem with the purging of the humanities from the study of business generally is that students never attend to the fact that marketing and management—not to mention economics—are forms of sophistry.  The sophist, as Socrates tell us, sells his skills and competencies with the claim that knowledge is for money, power, and individual freedom. He also claims to know more than he really does by claiming that we can know less than we really do. 

Contrary to what the sophists say, it's not true at all that we should rest content with the conclusion that money and power are for nothing more than whatever our personal preferences happen to be, with thinking that leads so easily to the conclusion that there's no human standard we share in common higher than personal productivity.

There's nothing wrong with being a sophist, to a point.  But the point of higher education is acquiring the civilized and humane knowledge of what that point is.  The logic of the market or whatever cannot and should not define whole human lives or enter into every human relationship.  The logic of the market shouldn't be limited or guided by mere "values" (even in the sense of "family values") but by virtues, including (but not only) the ones praised by Adam Smith.

The real problem, as I've said before, is the separation of knowledge into the sciences and the humanities—including the social sciences and the humanities—is based on artificial abstractions that we tend to forget are merely artificial abstractions.  One point of higher education is to see the limits of so-called academic disciplines, and that means being a lot more than merely "interdisciplinary." 

So, for one thing, economists would respect "humanists" more if they truthfully respected the real competence of economists and business leaders.  Professors of the humanities have to acknowledge that they share in the task of preparing students to be members of the productive meritocracy that shapes the 21st century global competitive marketplace.  After doing so, they can remind our economists that our best thinkers and leaders have always been and will remain more than sophists.  And higher education, for us all, is about much more than becoming an efficient sophist, because the world is much more than a marketplace.

An organism found in dirt may lead to an anxiety vaccine, say scientists

Can dirt help us fight off stress? Groundbreaking new research shows how.

University of Colorado Boulder
Surprising Science
  • 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."

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."
