Christmas makes no sense without Easter.

In Jesus of Nazareth, the Creator himself entered his creation to live among us. This is what Christians call the Incarnation. But why? What was the point of this identification with humanity? You might have expected these sorts of answers: he came to found the Christian religion, to teach us how to live and to gather a community of followers. These are true enough but look inside any church building or read any part of the New Testament, and you’ll find that another thing is the focus, something that makes Jesus different to any other founder of a religion. He came to die.

Jesus’ death is the climax of all four gospel stories. It is evident that the point of the narrative is there. The rest of the Bible’s New Testament spends more time describing the machinations that led to Jesus’ death than outlining what he taught. Does that mean it doesn’t matter what Jesus taught? Of course not: Jesus’ teachings matter tremendously to Christians. But his death matters still more.

No doubt you knew that. The first thing anyone learns about Christianity is its symbol, the cross on which Jesus was executed. One of the cruellest forms of capital punishment that has ever been legal, those executed on the cross were called ‘crucified’ – a word which still has its shuddering power even today. Crucifixion was a death reserved for the lowest of the low: common thieves, runaway slaves, rebels, and lawbreakers. Yet this particular death was the ultimate goal of Jesus’ life.

Why? What’s it all about? For Christians, Jesus’ crucifixion strikes at the very root of all that is wrong with the world. To understand it, first we have to understand what Christians believe about that.

If you fall into a pit you can’t climb out of, then lack of information is not your problem. Nor does it matter how many other people are in the pit with you: nobody down there can pull you or themselves out.

Everyone agrees the world in its current state is, to put it mildly, less than ideal. Most put it down to a lack of education, or to the stubborn foolishness of a few isolated individuals.

If you believe that people behave badly because they are ill-informed, then you might think the solution is to teach people what is right. You will put great faith in education: give people the information they need and they will change their ways.

Alternatively, if you believe ‘other’ people are the problem, you can focus your attention on opposing them, imprisoning them, or stripping them of power somehow. But Christians believe that the root of the problem is far deeper, such that these efforts only scratch the surface and will never be effective in the long run.

Christians believe that the whole of humanity has been damaged, cut off from its relationship to what matters by a primordial catastrophe that we call ‘the Fall’. Human beings are not simply ignorant, and the problem does not lie in lack of information, or education. The problem lies in our will, the part of us that chooses what is wrong even when we know full-well that it is wrong. And the problem is not just some people ‘over there’, conveniently set apart from me. Every single human being has been impacted. Including you. And me. Every one of us is part of the problem, which is why no one of us, however smart or well-informed we are, can be the solution. If you fall into a pit you can’t climb out of, then lack of information is not your problem. Nor does it matter how many other people are in the pit with you: nobody down there can pull you or themselves out. You need someone outside the pit who can reach down and grab hold of you.

That is why Christianity is more than a moral programme for self-improvement, or a set of spiritual practices comparable to those of other religions. According to Christians, the human race does not need another set of rules about how to live, or a formula to cultivate mindfulness and inner peace. We need a saviour: someone who does not share our fallen condition, but who can reach down and lift us to safety.

How far down did Jesus have to go? All the way to the bottom, which means death. Even the worst kind of death.

How did Jesus’ death save us? Christians have various theories about that. You may have heard the most common which uses law court imagery: we were guilty and sentenced capital punishment, but Jesus was punished instead so we don’t have to. Some people love this theory and live by it; others find it morally problematic and offensive. But the point is not the theory: the point is the reality to which it points. One way or another, by dying Jesus reconnected us to God and restored the broken relationship.

But it’s stranger still than that, because Jesus’ death is not the end. It was only the preliminary to something far more wonderful and transformative, a sign of a promise beyond our wildest hopes. By dying, Jesus defeated death itself and came back to life. If Christmas makes no sense without the cross, then the cross makes no sense without the resurrection. But more on that in my next article.

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.
