Why I teach over my students’ heads

Successful teaching is a work of empathy that stretches the mind.

I’ve been teaching college students for almost 30 years now. As much as I grumble during grading season, it is a pretty incredible way to make a living. I remain grateful.

I am not the most creative pedagogue. My preference is still chalk, but I can live with a whiteboard (multiple colors of chalk or markers are a must). Over the course of 100 minutes, various worlds emerge that I couldn’t have anticipated before I walked into class that morning. (I take photos of what emerges so I can remember how to examine the students later.) I think there is something important about students seeing ideas—and their connections—unfold in “real time,” so to speak.

I’ve never created a PowerPoint slide for a class. I put few things on Moodle, and only because my university requires it. I’ve heard people who use “clickers” in class and I have no idea what they mean. I find myself skeptical whenever administrators talk about “high impact” teaching practices (listening to lectures produced the likes of Hegel and Hannah Arendt; what have our bright shiny pedagogical tricks produced?). I am old and curmudgeonly about such “progress.”

But I care deeply about teaching and learning. I still get butterflies before every single class. I think (hope!) that’s because I have a sense of what’s at stake in this vocation.

I am probably most myself in a classroom. As much as I love research, and imagine myself a writer, the exploratory work of teaching is a crucial laboratory for both. I love making ideas come alive for students—especially when students are awakened by such reflection and grappling with challenging texts. You see the gears grinding. You see the brow furrowing. Every once in a while, you sense the reticence and resistance to an insight that unsettles prior biases or assumptions; but the resistance is a sign of getting it. And then you see the light dawn. I’m a sucker for that spectacle.

This is how the hunger sets in. If you can invite a student to care about the questions, to grasp their import, and experience the unique joy of joining the conversation that is philosophy.

Successful teaching is, fundamentally, a work of empathy. As a teacher, you have to try to remember your way back into not knowing what you now take for granted. You have to re-enter a student’s puzzlement, or even apathy, to try to catalyze questions and curiosity. Because I teach philosophy, my aim is nothing less than existential engagement. I’m not trying to teach them how to write code or design a bridge; I’m trying to get them to envision a different way to live. But, for me, it’s impossible to separate the philosophical project from the history of philosophy: to do philosophy is to join the long conversation that is the history of philosophy. So we are always wresting with challenging, unfamiliar texts that arrive from other times that might as well be other planets for students in the twenty-first century.

So successful teaching requires a beginner’s mindset on the part of the teacher, a charitable capacity to remember what ignorance (in the technical sense) feels like. To do so without condescension is absolutely crucial if teaching is going to be an art of invitation rather than an act of alienation. (The latter, I fear, is more common than we might guess.)

Such empathy means meeting students where they are. But successful teaching is also about stretching students’ minds and imaginations into new territory and unfamiliar habits of mind. This is where I find myself especially skeptical of pedagogical developments that, to my eyes, run the risk of infantilizing college students. (I remember a workshop in which a “pedagogical expert” explained that the short attention span of students required changing the PowerPoint slide every 8 seconds. This does not sound like a recipe for making students more human, I confess.)

That’s why I am unapologetic about trying to teach over my students’ heads. I don’t mean, of course, that I’m satisfied with spouting lectures that elude their comprehension. That would violate the fundamental rule of empathy. But such empathy—meeting students where they are—is not mutually exclusive with also inviting them into intellectual worlds and conversations where they won’t comprehend everything.

This is how the hunger sets in. If you can invite a student to care about the questions, to grasp their import, and experience the unique joy of joining the conversation that is philosophy, then part of the thrill, I think, is being admitted into a world where you don’t “get” everything.

This gambit—every once in a while, talking about ideas and thinkers as if students should know them—is, I maintain, still an act of empathy.

When I’m teaching, I think of this in a couple of ways. At the same time that I am trying to make core ideas and concepts accessible and understandable, I don’t regret talking about attendant ideas and concepts that will, to this point, still elude students. For the sharpest students, this registers as something to learn, something to be curious about. Or sometimes when we’re focused on, say, Pascal or Hegel, I’ll plant little verbal footnotes—tiny digressions about how Hannah Arendt engaged their work in the 20th century, or how O.K. Bouwsma’s reading of Anselm is akin to something we’re talking about. The vast majority of students won’t be familiar with either, but it’s another indicator of how big and rich and complicated the intellectual cosmos of philosophy is. For some of these students (not all, certainly), this becomes tantalizing: they want to become the kind of people for whom a vast constellation of ideas and thinkers are as familiar and present as their friends and cousins. This becomes a hunger to belong to such a world, to join such a conversation.

This gambit—every once in a while, talking about ideas and thinkers as if students should know them—is, I maintain, still an act of empathy. To both meet students where they are and, at the same time, teach “over their heads,” is an invitation to stretch into new terrain and thereby swell the soul into the fullness for which it was made. The things that skitter just over their heads won’t be on the exam, of course; but I’m hoping they’ll chase some of them for a lifetime to come.

Inheritance and environment's impact on ethics

Once discounted insights are now found important and have ethical consequences. Andrew Davison concludes his series on biology’s current developments.

There’s no more exciting work in biology at the moment than thinking about organisms in terms of their environment. That’s a crucial part of the lively current scene in evolutionary thought (which I described in my previous article), and part of how a new generation of fascinating writers is urging us to throw off the overly narrow perspectives of the twentieth century. It’s not that Darwin’s fundamental insights were wrong, just that some of his followers took them to rule out, or discount, features of biology that turn out to be real and important.

In fact, Darwin was often ahead of the game here. He was more interested in cooperation between species, for instance, than many writers who went on to champion his ideas. He wrote brilliantly about the relationship between moths and orchids, for instance, and between plants and earthworms. Similarly, as Jessica Riskin has recently pointed out, he never dropped the idea that what organisms do during their lifetime affects what they pass on to their offspring (what he called ‘use and disuse’). For much of the twentieth century, that idea, of passing on of acquired characteristics, was biological heresy, but today it’s making a comeback.

The excitement in contemporary evolutionary biology can usefully be gathered under two headings. Alongside ‘organism and environment’, there’s also ‘extended heredity’, although the two are closely related on some points. They’re both important as part of the sort of discussion presented on this site – run in conjunction with the Church of England, of all things – not just because it’s good for religious institutions to demonstrate enthusiasm for science, but also because they’re full of ethical consequences.

Passing on to the progeny

Take ‘extended inheritance’: extended, in the sense that there’s so much more that’s inherited from parent to child than just a DNA sequence. For one thing, every organism bequeaths a world to its progeny, which means a world that’s at least somewhat adapted: at least a little (as with some bacteria, although others are adept at ‘ecosystem engineering’) or massively, as when a beaver completely changes its surroundings by building a dam, or when human beings cover the Earth with marvellous and terrible things. The transformed landscape of the beaver and the human being, even of the bacterium, is part and parcel of what they each pass on to their progeny, and therefore part of biological inheritance. That really puts the environment back at the centre of our thinking about organisms and evolution.

Taking a wider view than genes-are-all-you-pass-on has no lack of consequences. In their accessible and endlessly fascinating 2018 book Extended Heredity, Russell Bonduriansky and Troy Day show that narrow-mindedness on that front has had terrible consequences. They see it behind the Thalidomide birth defect tragedy, for instance, and the strange unwillingness of medics, in the middle of the twentieth century, to take the dangers of foetal alcohol syndrome seriously. If it’s a matter of scientific dogma that all that matters is what genes parents give to their offspring, other factors – like bothering to monitor what effects alcohol have on pregnant women and developing child, or the effects on them of a new medicine – don’t look as important as they should.

Genes aren’t everything, especially in the developmental phase (from conception through childhood and adolescence). Throughout that period, in particular, genes and environment dance an intimate tango, with genes turning on and off in response to its experience of its environment, before and after birth. Moreover, recent science shows that what happens to you during your lifetime can even be passed onto your offspring, and even to their children after them.

That flies in the face of the idea that all you have to pass on is the genetic hand of cards you were delt at conception (or its equivalent, for instance for a plant). On that hallowed view, the most that life has to offer from that moment on is testing your ‘fitness’, to see whether you manage to pass those genes on, or not, or how abundantly. But that’s far too limited a picture. We don’t just pass on genes; we also pass on the pattern of how genes are tagged to be turned on or off, and that is changed by the conditions the organism has experienced.

Hunger lessons

The most striking, but gruesome, example involving human beings is the ‘Dutch Hunger Winter’ of 1944–45, when occupying German forces starved the Dutch population in retaliation for resistance victories. Children conceived during that period grew up with poor metabolism (or, to be more accurate, metabolism that would be good at surviving starvation, but was not well-adapted to healthier post-war life nutrition, which is fascinating in itself). So much for genes being everything. More startling still was the observation that their children also had poor metabolism: the grandchildren of the starved pregnant women. We can pass on acquired characteristics, which really puts the cat among the twentieth century Darwinian pigeons. As the prophet Ezekiel put it, ‘The parents have eaten sour grapes, and the children’s teeth are set on edge’. This is full of ethical freight. The way we treat other people, and ourselves, affects those who come after us: yes, socially and culturally, which is significant enough, but even in how their bodies are programmed to develop.

A stimulating environment

There’s a similar ethical charge to what is perhaps my favourite part of the newly boisterous world of biology: phenotypic plasticity. That’s the simple idea that the same genes (the ‘genotype’) will produce a differently structured organism (the ‘phenotype’) in response to different environments. In one sense, it’s obvious enough. If I go to the gym for a year – a particular kind of environment – I’ll look different afterwards than if I’d spend an equivalent length of time on the sofa.

But it goes much further than that. Various plants will produce different sorts of leaves, for instance, depending on whether they grow in more or less shady situations. Sometimes, one species can be mistaken for two, as happened with fish, called cichlids, in Lake Tanganyika (between Tanzania and the Democratic Republic of Congo). What scientists had thought to be separate species, because their jaws are so different, turned out to be the same species. If a fish grows up at the bottom of the lake, it develops one mouth shape, with large, strong jaws, for munching shellfish; if a it with the same genes grows up at the top of the lake, it develops delicate jaws, useful for eating other kinds of food.

Again, the repercussions of ethics are enormous, and that brings us back to the ugly subject of eugenics, mentioned in the first of these articles. At root, eugenics is based on the assumption that some people just are healthy, and others just are sick, because some have ‘good genes’, while others have ‘bad genes’. You are either blessed with the former, or doomed with the later, and that’s set in stone, from conception. It’s then (supposedly) the ‘right thing’ to promote the former when it comes to reproduction and, at its most horrific, to restrain, sterilise, or even slaughter the latter. Eugenics cast its shadow over more of the twentieth century than we might like to admit. At one time or another, it was the darling of both the political right and the political left. It hasn’t gone away.

Before we say anything else, there’s a moral flaw in thinking that concern for the gene pool trumps concern for suffering individuals. More than that, though, the biology shows eugenics to be flawed even on its own, supposedly scientific, terms. We aren’t just blessed or doomed by the genetic hand of cards we’re delt at conception. Like those plants, growing in sunlight or shade, what our genes will mean is also determined by our setting. Like those African fish, our genes can run more than one programme, so the environment matters.

Eugenics presents the all-to-convenient picture that the sick will be sick, the weak will be weak, and that’s that. But we’re not just doomed or blessed by genes. It matters, for instance, what sort of housing we have, how we’re fed, and whether we have access to fresh air and places for exercise, and to stimulus for the mind, and companionship. Putting people into groups (healthy and sick, or worthy and unworthy), then writing off one of those groups might be politically and economically convenient, but it’s bad science, as well as bad morals.

Reason to be curious

I started this series by mentioning how important the theology and philosophy of the Middle Ages has been for me, in working between theology and science. In one of his little read works, Thomas Aquinas (1224–1274) defended having the expansive curriculum used in training Dominican friars like himself. (It helped that this curriculum was being drawn up, in part, by Albert the Great – perhaps the greatest polymath of his century, and later patron saint of scientists.) One should be open to knowing about everything, Aquinas argued, because you never know what will come in useful later on. We have an excellent, and timely example of that, in how something as obscure as phenotypic plasticity bears on eugenics, and the eminently practical question of proper housing.

Recently, in fact, the Church of England has been working hard on housing. The Bishop of Chelmsford, Guli Francis-Dehqani, has the new housing brief among the bishops. The church’s council for Mission and Public Affairs has also been busy, not least with the publication of Coming Home: Christian Perspectives on Housing in 2020. What might have seemed like rather abstract wranglings among biologists, over where to put the emphasis in their theories about nature, turns out to show how right it is to be passionate about good housing (and, it turns out, about keeping abreast of biology).
