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).

Critics and curators are missing this about contemporary artists

An interview with Jonathan Anderson

Jonathan Evens

Jonathan is Team Rector for Wickford and Runwell. He is co-author of The Secret Chord, and writes on the arts.

Throughout much of the twentieth century, many modern artists engaged with religion in and through their work but art critics and art historians routinely overlooked or ignored those aspects of the work when writing about it. They did so because of a secularisation agenda that overrode reflection on key elements of the art that artists were creating.

In Modern Art and the Life of a Culture, Jonathan A. Anderson, together with William Dyrness, recovered some of the religious influences explored in the work of key modern artists by writing an alternative history of modern art. Now, with The Invisibility of Religion in Contemporary Art, Anderson has addressed the central issue, which is the way in which art critics and historians have written about modern and contemporary art.

JE: What is it about this situation – that modern art has often wrestled with God, but critics and curators haven’t always shared that focus – that engages your interest and motivates you to write so compellingly about it?

JA: The more I have studied and circulated through the worlds of contemporary art (first as an artist, then as a critic), the more attentive I became to significant disconnects in the ways we talk and write about religion in modern and contemporary art. Many prominent artists working today and over the past century have been shaped by religious traditions, and their works are in serious dialogue with those traditions in various ways and from various perspectives. Their relationship to religion might be highly conflicted or nuanced—it often is—but it is a live issue in their work and one can talk with them about it in their studios or in informal settings. But when one moves to the critical writing and public discussions about these artists’ works, this aspect either disappears altogether or is discussed in ways that are clumsy, stifled, or shapeless.

The aim of a lot of my work is to understand in a non-superficial way why this has been the case, why there has been a recent resurgence of discussions of religion and spirituality, and how we might develop more substantive ways of thinking and speaking about these topics.

JE: What did you find most surprising as you undertook the research for both books?

JA: I am consistently surprised at how sprawling and dense this topic is. Once one begins rethinking ‘the strange place of religion’ in the histories of modern and contemporary, the more one finds that there is an enormous amount of material that deserves renewed investigation. Both books give a strong sense of this, but chapter three in my new book is especially full of sign-pointers toward items that require further exploration.

To give one concrete example, I found myself referring to several major curated group exhibitions that, in one way or another, significantly address topics of religion and spirituality in twentieth- and twenty-first-century art. As I began to look more seriously at the history of such exhibitions, this curiosity swelled into a huge endeavour. Over the course of several years, I assembled a long list of exhibition catalogues and other documentation—the most comprehensive list of its kind that I’m aware of—which in turn helped me not only to recognize how prevalent interest in these topics has been but to think through the diversity of approaches. A version of this list is published in The Invisibility of Religion in Contemporary Art as an appendix, and the full, updated list is also available on my website. I hope it’s a valuable resource for others.

JE: Both books offer ideas and suggestions for constructive ways to understand, address and write about the relationship between art and religion going forward. In Modern Art and the Life of a Culture there is the idea of a charitable hermeneutic, while in The Invisibility of Religion in Contemporary Art you offer substantial new frameworks for discussing art and religion. Why is it important that the dialogue between art and religion finds paths to conversation rather than conflict?

JA: This is an important question. The public dialogue between contemporary art and religion has been relatively dysfunctional for much of the past century, often riddled with mutual antagonisms, melodramatic controversies, misunderstandings, and mutual unintelligibility. But art and religion are complex, vital domains of meaning that have continued to deeply shape each other up to the present and that have an enormous amount to ‘say’ to one another today, both critically and constructively. My own experience is that the more the participants in this conversation become attentive to and conversant in the other’s history, vernacular, and ways of thinking, the more highly constructive and mutually enriching the dialogue becomes.

I think this kind of dialogue has everything to do with cultivating mutual care and love of neighbour. The art world is a series of loosely connected communities full of people who are your and my neighbours. I happen to really care about these communities who make, exhibit, and talk about art, despite their problems. And the same might be said about various religious communities, who have their own problems and who often have more complicated interrelations with those art communities than is generally recognized. Wherever you’re coming from—the arts, the church, or otherwise—I’m interested in expanding dialogue oriented toward loving one’s neighbours, or even one’s enemies if that’s how it must be. At the most basic level, that means listening in a way that tries to discern others’ animating cares and concerns.

JE: Do you see any parallels or differences between the way the relationship between secularism and religion has played out in the world of art and the way the broader relationship between the two has been shaped in Western society in the same period?

JA: This is a fascinating but complicated question. For some people, the whole point of the artistic avant-garde was to enact and exemplify, in a highly concentrated way, the secularization of Western society. At the same time, however, it was also widely recognized that the arts have, in almost all places and times, been deeply interconnected with religion and spirituality, and this was, in some conflicted or repressed way, still likely the case for much of the avant-garde as well.

Secularization has meant the pressurizing and pluralizing of religious belief, sometimes corresponding to disaffiliation from traditional organizations, but this has relatively little to do with an eradication or obsolescence of religious belief. Indeed, any notion of what Rosalind Krauss memorably described as an ‘absolute rift’ between ‘the sacred’ and ‘the secular’ is really just shorthand for some kind of social conflict, because there’s not really any rational way to absolutize these as mutually exclusive. Whether acknowledged or not, religion still provides the metaphysical and ethical groundings of modern secularity, and modern secularity provides the social conditions for contemporary religion. In this context, distinctions between religiosity and irreligiosity are often ambiguous, running through each of us in unexpected and ever-changing ways (rather than simplistically separating us from each other). In my view, contemporary art is highly illuminating to these broader dynamics. Anyone who has spent any extended time in the worlds of modern and contemporary art knows that they are full of spiritual and theological struggle. To put it succinctly: contemporary art is not an art of unbelief and nonpractice but an art of conflicted, pressurized belief and practice, which is theologically significant if attended to as such.
