Pipe organs are one of my favorite instruments. Unlike most other musical instruments, these are built as part of the building that houses them. The building itself is the resonance chamber. Which means that when you enter the building you are entering the instrument.

Last night’s Aurora Borealis display shifted all my social media to photos of crimson ribbons across green skies. I welcomed the mood of delight, and liked every such photo I saw.

For my ancient and medieval philosophy students last night was a bonus. They’re required to stargaze throughout the semester, and to indulge in wonder like that of the ancients who contemplated the “music of the spheres.”

At times like this I am reminded of the words of C.S. Lewis:

“Those who brood much on the remote past or future, or stare long at the night sky, are less likely than others to be ardent or orthodox partisans.”

He doesn’t say we won’t be partisans, but that certain types of contemplation can make partisanship less likely. That is worth considering, and worth practicing.

This morning I spoke to a nature writing class at Middlebury College. The class is about rivers, so I spoke to them about my own writing, and my work in mussel ecology.

Students had good questions, perhaps because they have a good professor, Matthew Dickerson, who has taken them on regular field trips to visit the rivers and streams around their college.

Some of the questions students asked:

• How did you get interested in freshwater mussels?
• What can be done to restore mussels when their habitat has been impaired or they have been extirpated?
• Mussels benefit from host fish. Do the fish get any benefit from mussels?

I want to dwell on that last question for a moment:

Biology textbooks generally talk about symbiosis as being mutualistic (both species benefit), commensalist (one species benefits, one suffers no harm), or parasitic (one species benefits, one suffers harm).

There’s more to it than that, but that’s a big-picture overview: when we talk about symbiosis we want to know whether there is competition for resources (including the lives of the organisms involved), and which organisms gain benefits.

It’s a useful way to discuss the interaction between individuals in the short term.

Another way of looking at it is to think about the effects on populations and on ecosystems over a longer period of time. In other words, we can shift what we mean by “benefit” and examine it over the long run.

Most of the 300 or so species of freshwater mussels native to North America (mostly Unionidae species) have obligate relationships with host fish (or salamanders). A gravid female mussel mimics something fish eat, and when the fish bite, the young mussels (glochidia) are released into the fish’s mouth where they clamp down on the gills and other tissue, catching a free ride to their next home.

For a while, they live inside the fish, protected from predation and kept in the clean water that both fish and mussels need to survive. Eventually, they let go of the fish and find new homes in the river bottom, where they will likely stay for the remainder of their lives.

While the glochidia are attached to the fish, the fish has an immune response to the glochidia that eventually can protect the fish from future parasitism. If it sounds unattractive to have something live safely inside your lungs until it finds a new home, that might be how the fish feel, too.

So we could classify the mussels as obligate parasites. Obligate because they need the fish as both midwives and nurseries for their young, and parasites because the mussels benefit while the fish do not.

But if we expand the timeframe and the notion of benefit, we see a different picture. Mature mussels are filter feeders that can filter gallons of water a day. In a river or lake with a healthy mussel population, the water is cleaner, which makes it easier for the fish to breathe, and for the sunlight to reach further into the water, stimulating growth at a range of depths.

While the individual fish that plays host to the glochidia might be mildly harmed, without the mussels that already exist, that fish might not survive. And the fish’s descendants, perhaps many generations in the future, will benefit from the mussels that their ancestor carried at some personal cost.

In simpler terms: the grandparent might pay a price of hosting mussels in order for their grandchildren to live in a healthy environment. The hosting is a cost, but the thriving of the grandchildren is a benefit. It all depends on whether we are looking at the individual or the population, and whether we are thinking in the short term or the long term.

Of course there are other factors, and not all mussels, not all fish, and not all waterbodies are the same. But hopefully this one oversimplification serves as a counterbalance to another oversimplification in which we think only about short-term benefits for individuals.

I’ll end with a regret: I didn’t get around to talking about the importance of sketching what you see. I even had my sketchbooks and some excellent nature journaling books by my teachers John Muir Laws and Robin Lee Carlson on the desk beside me. But the conversation flowed in a different direction, so we never wound up touching on art. Oh, well. Next time, maybe.

The U.S. has an abundance of good colleges and universities. Many, facing budgetary challenges, choose to eliminate humanities programs.

Those programs (esp languages, history, and other programs teaching about cultural distinctives and communication) can benefit national security, diplomacy, and trade.

But enrollment in those disciplines is trending downwards, in part because they cost the same as any other degree, require hard work, and don’t lead to obvious high-earning jobs.

The benefit to the nation is more people who can help us all understand other nations.

The cost to the individual is money spent on an investment with a very long and potentially thin tail.

I studied languages in high school and college: Spanish, French, German, Russian, Greek, Latin. Also picked up some Nepali, Hebrew, Sanskrit, and a smattering of a few dozen other languages.

If you graduate with a degree in languages, people ask: are you going to teach or are you going to translate?

And I’ve done both of those things, but mostly I’ve used languages for other reasons, like:

• Reading news and scholarship that is not available in my primary language
• Teaching and doing research abroad
• Helping people in other nations to develop businesses
• Simply connecting with local people around the world

And I’ve learned a lot of poetry, scripture, and other literature in other nations. No matter where you are, if a book has lasted centuries, it’s probably got some story worth reading that will help you live a better life.

My students sign up for my humanities classes because they satisfy a general education requirement. Most of them don’t long to study philosophy, great books, history, or literature.

Thankfully, many of them wind up liking what they read. Often, students will take these classes in their final year of university, having put off something they dreaded, only to find they wish they’d taken it earlier so they could study more.

I also find that people who have been out of university for a long time wish they could return to school. Not for the homework and exams, but for the reading and discussion of big ideas.

Maybe fifteen years ago I offered to lead a semester-long in-person discussion at local pubs for people interested in studying Classical Chinese philosophy. I limited it to a dozen people so we could have seminars. Within an hour of offering the seminar on Facebook and Twitter, I had 45 people request to be let in.

It seems to me that universities are stuck in old ways, requiring a four-year degree for recent high school graduates, and then creating internal systems that make faculty across disciplines into rivals competing for curricular turf.

We could do things very differently.

If, instead of regarding students as clients, we regarded them as fellow citizens and fellow learners, we could show them what it looks like to continue to learn (presuming that we faculty do continue to learn, of course).

And we could invite them to study both skills that will help them to earn a living and attitudes about learning that will help them grow into a vocation, a calling, a full life.

We could even offer them tools that the world needs them to have, like deep engagement with old stories that invite a lifetime of reflection, and a useful understanding of the languages, literatures, histories, and cultures of the world.

Our universities are not only like large ships that do not turn easily; they’re also like large ships in narrow canals. Even if the pilots wanted to turn, the walls of the canal prevent changing course frequently.

Thankfully, what happens on individual decks of the ships often has a little more flexibility. Individual departments, honors colleges, and a few of us faculty who are willing to do far more than we are paid for wind up making a difference.

An administrator of one university recently told me that their faculty’s only value to the university is in the easily quantified number of bodies in seats in classrooms. I did not dwell too long on that because I had a grieving student who wanted to talk about her dying parent, and after that I was off to volunteer my time with a global technology challenge that benefits my university in numerous ways that are hard to quantify. I did spend a little time praying for that administrator and her faculty, though, because it sounded like they’re all feeling immense pressure, and responding poorly.

For now I will continue to be one of those faculty who meets with grieving students, who teaches students how to build furniture and how to grow food, who takes students on field trips, who mentors students in building skills, technology, and businesses, who volunteers with my city, with local high schools, and with non-profits. And so much more.

Because I don’t just teach classes. I teach people.

And because I believe that the formal curriculum is a mere shadow of what faculty offer through mentorship, community connection, lived experience, and relationships that grow over time.

And I hope—perhaps naively—that the result will be a long-tailed return for the whole world.

A page in one of the books I am writing for my grandchildren. One of them saw snow for the first time ever this weekend. So I wrote about that, and drew some pictures, and talked a little about how I have learned art and math and science. And about the beauty that emerges in each of those, and in nature.

Serviceberries in my garden, yesterday and today. Today my garden got its first blanket of snow.

Scenes from this morning’s Environmental Philosophy class. We read some Plato, some Henry Bugbee, a little about Maori philosophy, and poems by Billy Collins and Gary Snyder. I also brought hand warmers and a backpack full of wool and extra layers to share. It was warm in the sunlight, and we got to enjoy the shifting colors of autumn.

A morning sketch and watercolor of the view outside my office window. I used this to teach my students who came to my office hours, and to let them know that I am still learning, even at my age and rank. And to show them what I hope they will do in their own journals. What treasures are to be found right in front of us today?

Looking at the cost of informal logic / critical thinking textbooks for my students next spring and it’s absurd how expensive they’ve become. A big part of that is they all want to integrate with an LMS. But seriously, $150 for a textbook they won’t likely keep, or a similarly high price for one they will rent is ridiculous.

Thinking I will simply write my own text (I’ve been teaching logic for 25 years now, have loads of notes and references) using AI to clean it up for LMS integration.

Cost to my students: zero.

Benefit: combination of long experience and current topics and examples.

A link to my (unfortunately paywalled) article on Medium about religion and robots. Also for my students!

A link to my article on what I saw at NeurIPS last year. Putting it here to make it easier for my students to find it!

Today’s sketch, made while listening to a lecture. Decided to try drawing my own hands, my pen, and my sketchbook. Practice, practice, practice.

My wife recognizes the subject so I feel pretty good about this portrait.

Some single-line sketches from the past few days.

I carry this notebook with me almost everywhere these days, and use it to try to make quick renderings of what I see.

I’ve been experimenting with different media and different techniques, and each one has (I think) made me a better artist.

I think they’ve also made me a better scientist, a better philosopher, and a better teacher.

Perhaps most importantly: this practice has been a lot of fun. It feels good to do it, and it helps me slow down and see the beauty all around me.

It’s also interesting to see the accessibility descriptions that micro.blog automatically generates. When it recognizes what I have sketched, it’s a nice affirmation of my growth as an artist.

Today’s shelfie. These are books I used in teaching today.

Your challenge is to guess what I teach.

Shelfie.

These are books that I’ve brought to class this week or have pulled off the office shelves for discussions with students. Quite a few others have already been reshelved.

“Like a woven basket or a clay pot, a story is a container. It provides a shape for holding some character, some act or insight, some lesson we can’t afford to lose.” (Scott Russell Sanders)

Sanders says we are a storytelling species, that we make sense of the world through myths and stories.

Aristotle, two thousand years before Sanders, says “A man who is puzzled and wonders thinks himself ignorant (whence even the lover of myth is in a sense a lover of Wisdom, for the myth is composed of wonders.)”

(The words from Scott Russell Sanders are from the chapter entitled “The Warehouse and the Wilderness” in A Conservationist Manifesto. p 74. Indiana University Press, 2009. The words from Aristotle are taken from his Metaphysics, 982b, and the translation is from The Basic Works of Aristotle, Richard McKeon, ed. New York: Random House, 1941). That phrase “love of wisdom” is another way of saying “philosopher.”

The longer I’ve taught philosophy the more strongly I believe that it is a mistake to teach it outside of historical and cultural context.

Some of today’s delights:

• Chance meeting with a friend I haven’t seen in years, and who is flourishing in a new job.
• A quick visit with an alum who is doing great things with her life.
• Tea with an old friend who has also been an informal mentor.
• Dinner with two friends whose company and conversation fill my soul. (The food was also awesome!)
• Exchange of texts with a few other friends, with the plan to see one of them tomorrow.

Had so much fun I didn’t take photos or sketch, just enjoyed good company and good conversation.

Friendship is like manna.

One of the highlights of my week: singing a lullaby to my grandson in harmony with my son.
