    The Trace I Left Behind

    This summer I spent several weeks in and around Lake Clark National Park doing research on trout, salmon, and char. 

    Sometimes I get quizzical looks when I say that I, a philosophy and classics professor, am researching fish.  Let me explain.

    I teach environmental philosophy and a range of classes in what I call "environmental humanities."  These include courses in environmental ethics, nature writing, philosophy of nature, and even a course on environmental law and policy for first-year undergraduates, as an introduction to being a university student. 

    I also teach courses in field ecology, including a monthlong course in tropical ecology in Guatemala and Belize.  I teach in Greece over my spring break, and this year we will be looking at the expansion of fish farms in the Mediterranean and how fishing has changed there over the last six thousand years.

    Closer to home, I teach and practice what Norwegians call friluftsliv, or life in the free air.  Whenever possible, I teach outdoors.  Most years, I take my ancient philosophy students camping in the Badlands National Park to watch the Orionid meteor shower while we lie on sleeping bags under the stars.

    In all of this, my aim is to make sure that nature is not an abstraction to my students, nor to me.  I want to know the places the fish live, the grasslands the bison roam, the forests where the jaguar and the ocelot hunt, the tundra rivers where the Dolly Varden chase the salmon under the watchful gaze of the bears.

    In other words, my aim is to stay in contact with wildness, and to do so in a way that allows me to take something valuable home: intimate knowledge.  I am not a scientist, so I don't bring samples back to a laboratory.  I do bring home photographs, and I do spend a lot of time making observations of the places I work, so that I can bring home notebooks full of writing to share with my students. And of course, I write books and articles to share with others.

    This summer, I was sorely tempted to bring something else home from Lake Clark: a tiny fossil.  I had chartered a float plane to take me to a fairly remote lake, and there my fellow researchers and I walked the shore to the mouth of a stream full of spawning salmon and rainbow trout.

    Salmon preparing to spawn


    As I often do, I sat down on the gravel and started to turn over rocks to see what invertebrates were living there.  The salmon are bright red and eye-catching, but the bugs and spiders tell an important part of the story of a place, as Kurt Fausch has written about in his recent book, For The Love Of Rivers. Who was it - J.B.S. Haldane, perhaps? - who quipped that God has "an inordinate fondness for beetles." The world is full of wonderful, tiny lives that are easy to overlook.

    I don't try to bring beetles home, but one insect tempted me this summer.  Really, it was just a trace of an insect, just the trace of its wings, in fact.  I can't even tell you what insect it was.  All I can tell you is that somewhere near that river, probably millions of years ago, something like a dragonfly died in the mud, and the river graced its delicate wings with the cerement of silt.  That silt took the form of the wings, those wings left a fingerprint - a wingprint - on the earth.  And this summer, I found that print, that delicate, wonderful trace.

    Fossilized trace of an insect's wing


    While my son and my friend and our pilot walked, I sat with that stone in my hand and thought about pocketing it.  Here I was in the wilderness, and no one would know.  It's one tiny stone in the largest state in the union; who would miss it?

    Ah, but it is one tiny stone that does not belong to me.  It is one tiny stone in a vast wilderness that belongs to all of us, and to all who will come after us.  It is one tiny piece of rock with an incomplete fossil of a little odonata. The river there has held it and cared for it since time immemorial.

    Now I am back in South Dakota, but a tiny trace of my heart remains along the strand of that stream in Alaska. It lies there, wrapped around that delicate trace of insect wing, and I will never find it again in that vast wilderness.

    But perhaps someone else will.  Until then, perhaps it is best not to let Midas' longings turn our hearts to stone too soon.  Let's walk the shores together, I will continue to say to my students.  And let's bring something intangible home in our memories.  And let's do the hard work of leaving behind the beautiful, delicate traces that wildness has safeguarded for so many, many years.

    National Park Law - Knopf and Stegner

    Those who would protect the Parks and Monuments must rest their case always on the organic law that created the National Park Service. Any attempt to change that law would certainly bring on an instant and nation-wide and wholly bi-partisan explosion of protest. The danger is not that the law will be repealed or changed but that it will be whittled away through special concessions and permits. It is necessary to bear in mind Stephen Mather’s wise warnings when an advocate of whittling insists that he intends to create no precedents. With the best intentions in the world, he could not help creating a precedent. His successors in office might not agree with him about precedents, and they would have to use his own precedent against him.

    “The people, to whom the Parks belong, should be given the full facts on which to base a judgment, whenever the question of intrusion on Park lands arises. The people, as taxpayers who foot the bill, should also know, with fair exactness, and from a responsible reviewing body, how much a reclamation project is going to cost them, whether in a Park or not. [....]

    “The attitude of Americans toward nature has been changing—slowly, perhaps, but inexorably. Fifty thousand persons camped out in one Park, the Great Smokies, in a single summer month of 1954. That same summer I spent a night at Manitou Experimental Forest, in which a near-by campground, run by the Forest Service and at that moment without a water supply, was expected to be used by fifty thousand people before winter. In 1951 Glacier National Park had a half-million visitors; in 1953 it had more than 630,000. In that same year, the last for which total figures are available, Grand Canyon had 830,000 odd, Yellowstone 1,300,000, and Yosemite just short of a million. Those figures are impressive no matter how you take them. They mean that what the Parks and Monuments provide and preserve without impairment is increasingly appreciated and increasingly needed by more and more millions of American families.”

    South Fork, Eagle River

    After breakfast we put sack lunches in the cooler and threw our backpacks in the fifteen-passenger van. Half an hour later we were piling out at the state park on the South Fork of the Eagle River.

    The houses here are ugly. Taken on their own, any one of them is a beautiful building. Plainly this is spendy real estate in God’s country. But the houses look like they were lifted from the pages of some little-boxes-full-of-ticky-tacky architectural lust propaganda and carpet-bombed on the hillside, then allowed to remain wherever they fell. There is no order, no sense that the houses were built for the place. Every one of them is a garish, angular excrescence on the opposite hillside. No doubt their inmates would disagree with my assessment; they only see the houses up close, and from the inside. They must have no idea how out of place their unnatural rectangles look against the sweeping slope of the Chugach Range. No doubt, when you’re on the other side of those big plates of glass, gazing over here at the state park over your morning K-cup, the view is precious. But when you’re in the state park, looking back, there is nothing on the opposite hillside to love. Over here, there is only regret that these people believed that you could buy both the land and the landscape.

    It’s about three miles’ hike in to first bridge in state park. A fairly easy up-and-down walk. It’s raining. Spitting, really, what they call chipichipi in Guatemala, a constant drizzle. The sky is a palette of cottony grays that have lowered themselves onto the mountaintops. There is a clear line below which the mountains are visible. Above it, clouds roll and shift.

    I shiver a little in my heavy raincoat and think about putting on my rain pants, but I know I’ll be too hot if I do. Some of my students are wearing shorts.

    At the footbridge we sit and eat our lunches. The university has packed us red delicious apples (a mendacious name), bags of honey Dijon potato chips, and turkey sandwiches with lettuce and onions. It’s not good turkey, but no one cares. This is a lovely place. We have other food in this place.



    The river is only fifteen feet wide here, and it is the color of chalk, like diluted Milk of Magnesia. Taking off my shoes, I wade in.  Immediately my feet start to ache with cold. Turning over a stone, I look at its underside.  The gray water drips off and a tiny larva wriggles to get out of the light. It's too small to identify it, maybe a miniscule stonefly.  A huge blue dragonfly cruises over the river, darting past me.

    There are lots of wildflowers up here. One of my students is on the ground with her laminated guidebook, puzzling over one specimen. I've been carrying these guides everywhere, but they're only helpful for about seventy-five percent of the common stuff. There's just too much life here to get it all in a book.

    The flowers grow in so many colors, so many strategies for getting the scarce pollinators' attention in the brief summer. Yellows, purples, and blues predominate. The guidebook warns me about several of the purples: DO NOT EAT THIS! Some of them are poisonous.  So are a few of the yellows. This is a beautiful place, but it's also a harsh place, and life clings to the edge. Poison is one good way not to get eaten, I suppose. Looking up the mountain, the trees give way to shrubs a hundred yards above us.  A hundred yards more and there's only grass.  Above that, I can only see rock.

    Some of these plants have another strategy: rather than avoiding getting eaten, they invite it. Berries are the way some plants make use of animals to carry their seeds to new places.  Bear scat, full of seeds, is all along the trails here.  Each mound is a nursery where some new plant may grow in the fertile dung.

    There is a kind of berry like a blueberry that grows on something that looks like a mix between evergreens and moss, only a few inches high.  Some people call it "mossberry," appropriately.  Some locals call it a blackberry.  Matt tells us they're crowberries, as he gathers a handful. He eats some and then the students tentatively pick and eat some too.

    We spend three hours there at the bridge, observing. There's so much to see.  Some of us write, some draw, some stare at the peaks that surround us.  A few doze off.  I get out my watercolors and try to paint the landscape, but I'm quickly frustrated. There are so many greens and grays and blues, and I'm no good at mixing colors.  I keep painting anyway.  I can at least try to get the shapes right, I think, but I'm wrong about that, too.  The mountains are stacked up in layers, and the lines look clean and clear at first, but when I try to focus on them they blur into one another.  The hanging glacier at the end of the valley looms over us, silent and white and yet so eloquent.  The glaciers are what made all of this, and even though they have retreated, the river runs with their tillage, the plants grow in their finely ground dust, the smooth slopes were ground smooth by millennia of ice.

    Upstream, Brenden hooks his first-ever dolly varden. This is his first fish in Alaska. He is positively glowing with delight. He cradles it in his hand and then quickly returns it to the water pausing only to admire this vibrant glacial relic of a char.  It too depends on the glacier.

    The temperature is constantly shifting as the sun comes in and out of the clouds. Each part of the valley takes its turn being illuminated: the river shines like silver; the mountainside glows bright green and the rocks and bushes above the tree line cast sharp shadows; high in the valley small glaciers are bright ribbons streaking the blue granite. The clouds push the sunlight in ribbons across the valley. When we are suddenly in the light, we are warm.

    After a few hours we walk back to the car. No one wants to go. For a while we drive in luminous silence.

    Nature As A Classroom

    For the last two weeks my students and I have been in Petén, Guatemala, studying the ecology of the region. For half that time we stayed with local families. Our homestays were arranged by the Asociación Bio-Itzá, an indigenous Maya conservation organization that runs a Spanish school to support their work in preserving a section of the Maya Biosphere Reserve. The other half of the time we spent on the reserve and hiking the Ruta Chiclera, a forty-mile trek through the Zotz and Tikal reserves, vast areas of largely unbroken subtropical forest.

    These are not always easy conditions. Many hard-working Guatemalans live in poverty that is hard to conceive in our country; it is hot and wet except for when it is cold and wet; biting insects are everywhere; disease and snakes and thorny vines like bayal are constant threats.

    But it is also a beautiful place with astonishing biodiversity and remarkable people whose resilience and generosity always make me want to improve my own character. They welcome us into their homes and into their lives, and they are glad to see us come to appreciate the place they live.

    I expect that my students will forget much of what I say in my lectures and much of what they read in books. But I doubt very much that they will forget the people they have met here. Guatemala has gone from being an abstraction to a concrete reality. When they meet kind people of good character who have walked across Mexico and made it into the USA only to be caught and deported, "illegal immigrants" now have a face, a home, a family at whose table my students have received a nourishing and welcoming meal.

    Likewise, they will not likely forget the sound of howler monkeys at night or the experience of scrambling up Maya temples still covered in a thousand years of trees and soil. They won't forget the long walk in a deep green forest and the smells of tortillas and beans cooked over a wood fire.

    It is expensive to bring students so far. One could object that the money could be better spent on viewing the forest online or donating it to rainforest conservation. I disagree. I'm not in the business of dispensing information; I'm in the business of transforming lives, and not much transforms like full-bodied experience. Before we leave for Guatemala my students read papers written by wildlife conservation researchers. In Guatemala they meet those researchers in person and get to hear their stories. They hear in their tone and see in their eyes what brought them to Guatemala and what keeps them here. In such times my students go from taking in data to rethinking their lives.

    It is my hope - my exuberant, perhaps not wholly rational hope - that out of such lived experience of nature my students will become people who comfort orphans and widows in their distress, who receive the foreigner into their own homes, who marvel and the world's diversity and who, for the rest of their lives, work to preserve it.

    Wendell Berry: Past A Certain Scale, There Is No Dissent From Technological Choice

    “But past a certain scale, as C.S. Lewis wrote, the person who makes a technological choice does not choose for himself alone, but for others; past a certain scale he chooses for all others. If the effects are lasting enough, he chooses for the future. He makes, then, a choice that can neither be chosen against nor unchosen. Past a certain scale, there is no dissent from technological choice.”

    Walking In Nature - In Sioux Falls

    Thoreau writes that not many people know the art of Walking.  I am trying to learn it, and I think part of it involves learning to see what is there.  My friend Scott Parsons has helped me to see better by teaching me to draw, since the pencil forces me to pay attention to what I actually see rather than just what I think I see.

    Lately I have been trying to walk more - that is, to Walk more - in and around my city, Sioux Falls.  I find, as I step off the sidewalks and walk a little more transgressively, the city is transformed.  The habits of sidewalks and cars speed up the world around us until much of it vanishes in a blur.

    Thoreau recommends trans-gressing, that is, stepping across paths and fences rather than letting them herd us to the destinations that habit and tradition and fetishized commerce want to lead us.  Once he wrote that we should sometimes bend over and look at the world upside down.  Sometimes this is all the "transgression" that is needed to overcome the aggressive habits that constrain us in daily life.

    Another tool I have used lately is the camera, peering down its glassy pipe at single, simple things, trying to break up the landscape by gazing intently at just one point.  Or, at times, using the lens to draw the world together, to see how much I can gather into its frame.

    When I first moved to Sioux Falls almost ten years ago I thought it was a homely place, a city that did not care for design or good planning or beautiful architecture.  Slowly, one frame at a time, I am changing my own mind.  As I Walk through and around it, I am coming to see that it is, at times and in places, quite a lovely place to live.






    Evolution and Education

    Sometimes I meet students who are afraid that evolutionary science poses a threat to their belief in God.  I think it is helpful for them to ask themselves this question:
    Is God capable of creating through natural processes?
    There are only two answers to this question.  If you say no, you make God too small to be worth worshiping.  If you say yes, then you see that there's no prima facie reason why belief in God and belief in evolution need to be opposed to one another.

    Of course, this doesn't clear up all the obstacles to reconciling religious belief and confidence in science, but it's a start.

    ***** 


    *****


    If you're a teacher of students who also grapple with this, and you don't understand them, this might help.  Some of them will certainly be unreasonable.  For them, sometimes all you can do is be an example of reasonable beliefs and hope it sinks in someday.  But many of them are concerned about a few big questions, like these:
    • The trust they've placed in their community.  Think about it: if your parents or your pastor or someone else you trusted taught you that there's an irreconcilable conflict between science and faith, you might distrust anyone who said otherwise.  It might help such students to go back to that community and ask the question I posed above.  This may take time, because there's a lot at stake here.
    • An even bigger concern is the question of human dignity.  I think that's what's behind the old complaint that "I'm not descended from monkeys."  If the student is simply concerned about being descended from unwashed furry critters, they should probably look more closely at their family trees.  Monkeys are often nicer than our actual relatives.
    • But there's another concern here that's actually quite positive, because it means that they care about ethics, and they're trying to preserve that in the face of a perceived threat.  Some students correctly intuit that what's at stake in evolution is not merely a theory of descent but a whole theory of knowledge, and of metaphysics.  Natural sciences rest upon an assumption of methodological naturalism.  That is, they assume that it is possible to explain natural phenomena by appeal to nature and nothing else.  So far, so good.  But sometimes we then make a little leap to saying that therefore whatever naturalism cannot explain is unknowable or nonexistent.  This is not just naturalism but a kind of reductionistic naturalism, and it's tricky territory, because it might imply that there is no real basis for ethics, or for valuing others' lives.  I'm not saying we're not free to value others' lives; I'm just saying that some of these students want to believe that there are good reasons to expect everyone to value everyone, not merely a world of subjective interests.  And many of them are reasonably suspicious that reductionistic naturalism cannot itself be supported by science; after all, how could natural science prove that what it can't see isn't there?  Such claims sound a bit like the misdirection of Wizard of Oz: "Pay no attention to the man behind the curtain!"  We'd be better off avoiding such claims, both because we cannot prove them and because they do a disservice to science.
    Acknowledging your students' concerns will help them to see that you care about them as people and not just as names or numbers on a page.  Which will already begin to address their deepest concerns.

    The Course Of Nature and Laws of Nature

    As part of the sabbatical leave I am currently enjoying I am spending a lot of time reading ancient and medieval texts, mostly on science and mathematics.  The plan is to incorporate them into my ancient and medieval philosophy class next fall.  I teach that class more as a history of texts than as a class on philosophical problems.  The historical development of astronomy is one of the main threads we follow, tying it to discoveries in geometry, optics, metaphysics, ethics, epistemology, and politics.

    Today I was reading this text from Book I of Manilius' AstronomicaI'll translate the relevant part below.
    Nam neque fortuitos ortus surgentibus astris
    nec totiens possum nascentem credere mundum
    solisve assiduous partus et fata diurna,
    cum facies eadem signis per saecula constet,
    idem Phoebus eat caeli de partibus isdem
    lunaque per totidem luces mutetur et orbes
    et natura vias servet, quas fecerat ipsa,
    nec tirocinio peccet, circumque feratur
    aeterna cum luce dies, qui tempora monstrat
    nunc his nunc illis eadem regionibus orbis,
    semper et ulterior vadentibus ortus ad ortum
    occasumve obitus, caelum et cum sole perennet.
    The boldface text could be (loosely) translated like this: "Nature follows paths that she herself has made, and she does not stray as the inexperienced do." 

    On the one hand, this sounds like an early articulation of the idea of laws of nature.  If nature follows paths laid down by nature itself and from which it does not deviate, that would be compatible with our idea of a natural law.

    Yet there's an important difference between law and path. As you walk along a path, your feet may fall more to one side of the path or the other; and over time, paths may shift, broadening with use or narrowing with desuetude. Charles Peirce, responding to advocates of Hume's argument against miracles, argues that nature is like this as well, and that what we now call laws were once called  the course of nature, and Peirce thinks of them as habits that nature has taken on.

    The name makes a difference, if only a slight one. Peirce was not trying to argue for particular miracles, but he was urging students of science not to insist that nature behave according to their preconceptions of law.  Manilius' idea is not so far-fetched: the laws might not have been there at all, but nature took them on and then, once they became habits, nature has stuck to them. Thinking about science this way alerts us to two possibilities: first, that things might not always have been as they are, and second, that nature might still be taking on new habits.  We shouldn't expect nature to stray far from its habitual paths, but on the other hand, what would prevent it from doing so?

    Do You Know The Phase Of The Moon?



    I like to begin my class on ancient and medieval philosophy with two questions: (1) Do we know more about the moon than they knew five centuries ago?  (2) Do you know what phase the moon is in right now?



    Of course, most of us would say "yes" to the first question, and with good reason.  After all, we've been to the moon several times, and we've brought samples back.  We have remarkable technologies for remote sensing.  The sciences have gone beyond what most people even a century ago could have imagined.

    The second question might be harder to answer without looking up the answer somewhere.  When I ask my students, usually none of them know the current phase of the moon.  A recent facebook poll I gave my friends yielded many more positive replies to the second question.  Not a very scientific poll, since it might be that many who did not know simply chose not to reply out of shame.  Still, fewer than half of those who replied said they did know the moon's current phase.

    I can think of no reason to be ashamed of not knowing the phase of the moon.  Most of us have no need to know it, and I don't ask the question in order to scold my students, but to point out something about how our knowledge has changed. It seems likely to me that five hundred years ago many more people would have been aware of the phase of the moon.  Children who play outside, farmers, fishers, sailors, and soldiers all wind up depending on the moon, or at least having considerable exposure to it.  Today, very few of us have reason to notice it, because our lives have changed so much. 


    This brings me back to my first question: do we know more about the moon today than they knew five centuries ago?  In one sense, the answer is still obviously "yes."  But in another way, it has to be "no."  Most of us (myself included) don't pay much attention to the moon.  Our knowledge of its phase is not the knowledge of familiarity but rather confidence that, if we needed to know, we could look it up somewhere.  We have confidence in the knowledge of our community, and of its possession of data.

    Which leads me to a third question: Is it enough to know that someone else knows the answer?  Sure, we don't need to know what the moon looks like right now.  But if you haven't taken a little time to stare at it lately, you might have forgotten something worth knowing: the moon is beautiful.  Go have a look.

    The Ethics of Hunting

    According to the myth, Actaeon the hunter was turned into a stag and torn to pieces by his own dogs.   Many versions add that this was because Actaeon offended Artemis.  He viewed her as she bathed, or he attempted to violate her.  His punishment was to be transformed from hunter to hunted.  His own dogs did not recognize him as they devoured him, (though Apollodorus adds that they later grieved as they searched for their master.)


    Just as there are many versions of the myth, so there are many interpretations, and many things that Actaeon and Artemis might symbolize.  The divinity of Artemis suggests to some that hunters seek something much loftier than meat for their table.  Her femininity and virginity suggest to others that hunting represents sexual violence in another guise.

    Both of these may be correct, but let me offer a third possibility: perhaps this is a story about virtue.  Actaeon acts without virtue, and he then becomes the victim of his own plans.  He makes the mistake of thinking that a hunter is the rightful possessor of all he sees, and so he fails to act with humility and gratitude.  As a result, he loses everything, including those relationships that were most dear to him.

    The myth of Actaeon is a vivid picture of what good hunters know: the hunter is not lord of the forest nor master of nature.  Most of us live our lives as far from predation as we can arrange.  A certain type of hunter attempts to erase some of that distance.  The best hunters may be those who, in doing so, discover their true place in nature and emerge from the forest and field remembering their place with humility and gratitude.  Actaeon forgets who he is when he attempts to take Artemis as his own, and his forgetfulness is absolute.  


    Socrates and the Trees

    It's always dangerous to assume one knows what Plato thinks, since Plato goes out of his way not to tell us what he thinks.  Nevertheless, inasmuch as Socrates is his mouthpiece, here is one place where I think Socrates is mistaken.  Socrates, speaking to Phaedrus, says, "I'm a lover of learning, and trees and open country won't teach me anything, whereas men in the town do." (230d)

    I disagree with what Socrates says here, and it is an unfortunate fact of history that many Platonists have taken a similar position to this one.  I just read this line in an otherwise very good book, David Keller and Frank Golley's The Philosophy of Ecology: From Science To Synthesis.


    It's a fine collection of key articles in environmental philosophy.  In the introduction, however, they contrast Socrates with Thoreau - something Thoreau himself did - and make Thoreau out to be the one more interested in trees.  Thoreau was interested in trees, especially at the end of his life, but that does not make the comparison apt.

    The irony of this line is that it comes from a dialogue in which Socrates continues to point out to his interlocutor just how much one can learn from a close observation of nature.  He repeatedly draws attention to the trees, the water, and the cicadas.  Socrates and Plato are not known as fathers of empiricism, but the view that their heads are so far in the Clouds that they cannot see the well they're about to step into has occupied too much of our attention.  We would do better to notice that Socrates pays attention to the trees.  We would do better still to pay some attention to the trees ourselves.
