Evolution isn’t just an idea for me; thinking about it has changed the course of my life. I arrived at university in the 1990s having been a member of a house church, full of the kindest people, but fundamentalist when it came to the Bible. I thought that the world was made in six days, six thousand years ago. When I realised that the evidence is stacked against the idea – to say theleast – it almost cost me my faith.

I got through that crisis because friends introduced me to Christian thinkers from the Middle Ages, especially Thomas Aquinas (1224–1274). Far from representing an age of fear and ignorance (the ‘Dark Ages’), I found there an intellectual world that thrived on questions, with such philosophical sophistication that I was sure any of its chief exponents could have taken evolution in their stride. The struggle between faith and science lifted. Eventually, the sorts of questions that had previously kept me awake at night in worry, kept me awake in wonder. That was almost thirty years ago. Today, contemporary developments in evolutionary theory are one of the main strands of my work as a theologian.

In two further articles, I will describe some of what’s so interesting, and disputed, in biology and evolution at the moment. In one, I’ll talk about the shift away from the idea that we can reduce everything down to the working of genes. That’s sometimes called an example of ‘nothing-but-ery’: here, the claim that our destiny is ultimately about ‘nothing but’ genes. In the other, I’ll talk about some of the ethical repercussions that those contemporary evolutionary developments might suggest, on such practical matters as good housing.

In the rest of this piece, however, I will stick with the idea that it’s useful to see the idea of a tension between religion and science, not least over evolution, as being as much personal as intellectual. In particular, tensions over evolution in ‘science vs religion’ are caught up with questions of identity. Seeing oneself as a ‘religious crusader against science’ or a ‘scientific crusader against religion’ is an identity. It’s part of the story you tell about yourself, part of what you take pride in. Since these are also identities that define themselves in opposition to one another, they tend to extremes. Reconciliation involves renegotiating one’s identity.

Nor is money insignificant. There’s money to be made in writing shrill and divisive books, but in calm and conciliatory books, not so much. Angry books create interest on social media. They find to an already energised readership. Moderate books, and authors who try to dampen the flames of animosity, don’t sell that well; neither do books that are willing to say ‘actually, these questions are more complex, or nuanced’.

Evolution and economics

Crucial in these questions of identity is the gulf between those seen as the ‘elite’ and those who don’t see themselves that way (a common theme in politics today). Why is a denial of evolution more common in poorer communities? It’s not only that these are people without educational advantages. It’s also that they feel on the disadvantaged side of an economic and cultural system. In that situation, people are typically all the more invested in what the system can’t take from them, such as their ethnicity, their religion, and its culture. Good on them for that. People in that situation will be all the more unwilling for others – whom they perceive as an elite, who enjoy all sorts of worldly advantages – to tell them what to think about their biological origins, bound up, as they are, with dignity, faith, and self-understanding.

As an economically disadvantaged Muslim man once put it to me, ‘No one’s telling me that my faith’s stupid, or that I’m just some sort of monkey.’ There’s so much more going on in that statement than ‘being wrong about the science’.

Moreover, disadvantaged people, and especially the majority who don’t have white skin, have been on the receiving end of prejudice cast in evolutionary terms. Teaching the theory of evolution – glorious though it is as a work of science – has a checkered moral history. That brings us back to monkeys. The ‘Scopes Monkey Trial’ (1925) has achieved iconic status, as the triumph of science over superstition in rural Tennessee, but it’s more complex than that. The prosecution, with its anti-evolutionary stance, was wrong to dismiss evolution as a matter of science. They weren’t wrong to be repelled by the science textbook at the heart of the case, which was uncomplicatedly racist, and indeed racist on supposedly evolutionary grounds. Evolution, it claimed, had produced lesser (black) and more advanced (white) races. As historians have also shown in recent decades, evolution was a powerful inspiration, into the early century, for advocates of cut-throat economics and politics: winner-takes-all, survival of the fittest, let the poor go to the wall.

I’m not saying that every bit of opposition to evolution among poorer communities rests only on the ways that evolutionary theory has been used against them, but it is useful to remember that some of the religious opposition to evolution in the twentieth century came from a principled response to the unpleasant ethical, political, and economic positions to which – they were told – evolution gave support, including full-on advocacy for eugenic programmes of sterilisation of the poor, and contempt for the physically weak: all clothed in evolutionary garb.

Drama critique

The spectacle of a ‘science vs religion’ drama turns out to be about more than science, and also about more than theology or religious belief. It’s also about identity, advantage and disadvantage, about some deeply unpalatable economic and social positions, and even about making money out of writing books. There’s everything to be said for teaching biology well, and for arguing about the truth of evolution on scientific terms. I do a fair bit of that myself. There’s everything to be said for teaching theology well, and for arguing that it can take evolution in its stride. That’s even more my aim. But neither offers the full picture, and it’s not helpful to think that anyone who doesn’t believe in evolution is simply stupid or wicked. We won’t get very far, not even as advocates of science, unless are willing to listen. Unexpectedly, my experience is that the flagship scientific societies in the United States (where tension over evolution run so high) are better at this than they are in United Kingdom.

Getting trapped in one end of some mutually reinforcing antagonism is hard to shake. It’s difficult to get to a nuanced position when you’re dealing with positions that are defined against each other. Whether arguments about evolution are part of your experience or not, there’s a wider message here, which we might all do well to take on board, asking ourselves whether positions of animosity can become unhelpfully baked into our sense of ourselves.

Accepting evolution does not naturally, or inevitably, lead to brutal social Darwinism, but it’s been used that way in the past, more often than coverage of science today often lets on. We are by no means out of its shadow, even from under the shadow of eugenics. Being aware of that big, historical picture is useful, but it shouldn’t obscure the message from the beginning of this article, that these matters are fundamentally personal, and as much about how we see ourselves, and others, as they are about ideas. Reconciliation and understanding happen person by person, and person-to-person.

You might think the work I’d most relish as a priest and scientist, or think most useful, would be reassuring religious people that evolution isn’t their enemy. That’s a good thing to do, but I’m actually even more thankful for opportunities to reassure scientists that religion can be thoughtful, unafraid, and even downright passionate about science. Turning up to dinner in my college still in my cassock after evensong, sitting next to visiting scientists, and asking intelligent, enthusiastic questions about their science can do as much good as all the lectures I give in churches or to theology students about the irreplicable value of science.

Whether it's AI or us, it's OK to be ignorant

Our search for answers begins by recognising that we don’t have them.

When was the last time you admitted you didn’t know something? I don’t say it as much as I ought to. I’ve certainly felt the consequences of admitting ignorance – of being ridiculed for being entirely unaware of a pop culture reference, of being found out that I wasn’t paying as close attention to what my partner was saying as she expected. In a hyper-connected age when the wealth of human knowledge is at our fingertips, ignorance can hardly be viewed as a virtue.

A recent study on the development of artificial intelligence holds out more hope for the value of admitting our ignorance than we might have previously imagined. Despite wide-spread hype and fearmongering about the perils of AI, our current models are in many ways developed in similar ways to how an animal is trained. An AI system such as ChatGPT might have access to unimaginable amounts of information, but it requires training by humans on what information is valuable or not, whether it has appropriately understood the request it has received, and whether its answer is correct. The idea is that human feedback helps the AI to hone its model through positive feedback for correct answers, and negative feedback for incorrect answers, so that it keeps whatever method led to positive feedback and changes whatever method led to negative feedback. It really isn’t that far away from how animals are trained.

However, a problem has emerged. AI systems have become adept at giving coherent and convincing sounding answers that are entirely incorrect. How has this happened?

This is a tool; it is good at some tasks, and less good at others. And, like all tools, it does not have an intrinsic morality.

In digging into the training method for AI, the researchers found that the humans training the AI flagged answers of “I don’t know” as unsatisfactory. On one level this makes sense. The whole purpose of these systems is to provide answers, after all. But rather than causing the AI to return and rethink its data, it instead developed increasingly convincing answers that were not true whatsoever, to the point where the human supervisors didn’t flag sufficiently convincing answers as wrong because they themselves didn’t realise that they were wrong. The result is that “the more difficult the question and the more advanced model you use, the more likely you are to get well-packaged, plausible nonsense as your answer.”

Uncovering some of what is going on in AI systems dispels both the fervent hype that artificial intelligence might be our saviour, and the deep fear that it might be our societal downfall. This is a tool; it is good at some tasks, and less good at others. And, like all tools, it does not have an intrinsic morality. Whether it is used for good or ill depends on the approach of the humans that use it.

But this study also uncovers our strained relationship with ignorance. Problems arise in the answers given by systems like ChatGPT because a convincing answer is valued more than admitting ignorance, even if the convincing answer is not at all correct. Because the AI has been trained to avoid admitting it doesn’t know something, all of its answers are less reliable, even the ones that are actually correct.

This is not a problem limited to artificial intelligence. I had a friend who seemed incapable of admitting that he didn’t know something, and whenever he was corrected by someone else, he would make it sound like his first answer was actually the correct one, rather than whatever he had said. I don’t know how aware he was that he did this, but the result was that I didn’t particularly trust whatever he said to be correct. Paradoxically, had he admitted his ignorance more readily, I would have believed him to be less ignorant.

It is strange that admitting ignorance is so avoided. After all, it is in many ways our default state. No one faults a baby or a child for not knowing things. If anything, we expect ignorance to be a fuel for curiosity. Our search for answers begins in the recognition that we don’t have them. And in an age where approximately 500 hours of video is uploaded to YouTube every minute, the sum of what we don’t know must by necessity be vastly greater than all that we do know. What any one of us can know is only a small fraction of all there is to know.

Crucially, admitting we do not know everything is not the same as saying that we do not know anything.

One of the gifts of Christian theology is an ability to recognize what it is that makes us human. One of these things is the fact that any created thing is, by definition, limited. God alone is the only one who can be described by the ‘omnis’. He is omnipotent, omnipresent, and omniscient. There is no limit to his power, and presence, and knowledge. The distinction between creator and creation means that created things have limits to their power, presence, and knowledge. We cannot do whatever we want. We cannot be everywhere at the same time. And we cannot know everything there is to be known.

Projecting infinite knowledge is essentially claiming to be God. Admitting our ignorance is therefore merely recognizing our nature as created beings, acknowledging to one another that we are not God and therefore cannot know everything. But, crucially, admitting we do not know everything is not the same as saying that we do not know anything. Our God-given nature is one of discovery and learning. I sometimes like to imagine God’s delight in our discovery of some previously unknown facet of his creation, as he gets to share with us in all that he has made. Perhaps what really matters is what we do with our ignorance. Will we simply remain satisfied not to know, or will it turn us outwards to delight in the new things that lie behind every corner?

For the developers of ChatGPT and the like, there is also a reminder here that we ought not to expect AI to take on the attributes of God. AI used well in the hands of humans may yet do extraordinary things for us, but it will not truly be able to do anything, be everywhere, or know everything. Perhaps if it was trained to say ‘I don’t know’ a little more, we might all learn a little more about the nature of the world God has made.
