How Do We Know How To Live? ... How Adulting Schools Arose

Storied skills and a musical analogy might help us update the logic of "virtue ethics." In life, as in jazz, freedom without skills results in a lot foolish noise.

1. How do we know how to live? What to aim for in life? Ways of life vary, but all need storied skills (and their life-structuring logic).

2. Each culture’s “storytelling resources… are of great political and moral importance,” says Alasdair MacIntyre (they’re a “chief means of moral education”; morals = co-living norms; politics = public morality).

3. The “moral of” a story retains an older sense of “practical lesson” taught, from Latin moralis, translating Greek ethikos, “pertaining to character” (neither language had “a word correctly translated by our word moral”).

4. Prior character-forming stories (e.g., from religions or philosophies) face newer story-making agendas e.g., lifestyle vendors, or art-serving and self-serving artists (sometimes oblivious to art’s life-structuring effects).

5. Shifting story-practices caused “something like a mutation in human nature” ~400 years ago. Lionel Trilling says that‘s how once socio-centric, role-and-relationship driven Westerners “became individuals."

6. Harold Bloom amplifies Trilling (over-dramatically)—“Shakespeare… invented the human” (characters narrating inner lives in “modern” ways).

7. Novels spread this “mutation” (they’re a “sophisticated technology of selfhood"—Vikram Chandra). Novelists became “engineers of the soul” (Stalin), transmitting the “big stuff” (Obama).

8. Philosophy once explicitly shaped novels. D. H. Lawrence called Plato’s Dialogues “queer little novels,” lamenting that “philosophy and fiction got split.” Philosopher and novelist Rebecca Goldstein notes that Middlemarch and Moby-Dick were, like her novels, philosophy-fueled. Likewise for Atlas Shrugged (once reportedly 2nd in influence to the Bible).

9. However unfashionable it seems to some artists (e.g., Nabokov didn’t “give a damn about public morals”), stories and art embody and enact moralities, philosophies, and psychologies (often folk not formal, naive not schooled, often tacitly/unwittingly). 

10. But “the only art that escapes social, or ethical, or political effects is art with no audience. Part of what art does is preach… intentionally or not.” Its glorying power often focuses now on what’s prestigious or fun in art (but can be ruinous in life).

11. Soul-engineering is shifting again; MacIntyre notices “new kinds of storyteller and story.”

12. Text-centric “Gutenberg minds” are waning. Ambient ads spread consumerism’s glamorizing how-to-live stories ad-nauseum (with “hidden brain” learning effects). Video game patterns separate players “from their humanity” (Ian Bogost).

13. Economists also preach life-and-world-structuring stories that sometimes increase selfishness (+ untrustworthiness, + see Fiction vs. Economics on Human Nature; + short history of individualism).

14. MacIntyre prefers life-structuring stories leveraging Aristotelian virtues—seeking rationally educated desires, above non-rational appetites/emotions (see, feelings = fast thinking, + Plato’s Pastry).

15. MacIntyre’s “virtue ethics” needs an updated vocabulary. Virtues are logical life skills, and virtue ethics teaches practical ways to avoid low-skill living (some need “adulting school,” or The Marines to teach successful adult" skills—JD. Vance).

16. A musical analogy might resonate—in life, as in jazz, freedom without skills, is just foolish noise. How could unskilled freedom be desirable?

Two MIT students just solved Richard Feynman’s famed physics puzzle

Richard Feynman once asked a silly question. Two MIT students just answered it.

Surprising Science

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.

Our ‘little brain’ turns out to be pretty big

The multifaceted cerebellum is large — it's just tightly folded.

Mind & Brain
  • 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."

Economists show how welfare programs can turn a "profit"

What happens if we consider welfare programs as investments?

Politics & Current Affairs
  • 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.
