No one on the planet can pretend not to care about death or about a way to overcome it. The heart of the Christian message is that death has been overcome. This isn’t just about immortality. It’s about Resurrection: the triumph of life over death. If we want to see why that matters we need first to face the reality of death squarely and without flinching. The best person to help us do that is Martin Heidegger.

It is unfortunate that one of the most influential philosophers of the twentieth century is also among the hardest to understand. There are even philosophy professors who avoid Heidegger’s work and refuse to talk about it (his associations with Nazism and antisemitism don’t help either). Yet for all that, his fame and influence continue unabated. Why? Perhaps it is due to the bold way he points to realities at the heart of the human condition. Realities like death.

Nobody can avoid death. No matter how rich, healthy, successful, or famous you are, death comes to you as it came to everyone before you.

If you dare to open Heidegger’s most renowned work, Being and Time, you will find a description of human existence as being-towards-death. What on earth does that mean? It starts with Heidegger’s claim that time is part of our very essence. We are time-bound beings. And the way in which we are time-bound has a direction: the future. Anxiety about the future constitutes our existence. We never stop being anxious: about where our lives are going, whether we will achieve our goals and dreams, whether our loved ones will be safe and happy, even (for some) whether we will survive another day. Only the most downtrodden and dehumanised in society have lost this forward-looking drive. The rest of us live most of our lives in our own projected future. Earning money, getting engaged, buying a house, getting a secure job, raising children: almost everything we do is future-oriented.

Yet our ultimate future faces us all as a horrifying reality we can’t avoid, that we spend most of our lives trying to ignore. We are all going to die.

Nobody can avoid death. No matter how rich, healthy, successful, or famous you are, death comes to you as it came to everyone before you. The greatest emperors, the wealthiest entrepreneurs, and the most famous superstars in literature, music or art have no advantage over the lowliest peasant. Death is the great leveller. And what of all that achievement then? What does it mean?

Death puts an end not only to ‘worldly’ ambitions like the above, but also to more meaningful pursuits like love, family, and relationships. Whoever you love will die too. This was the terrible truth that the Russian novelist Leo Tolstoy learnt. After decades of promoting family as the true meaning of life, he realised that he was simply passing the buck to the next generation. Unless each individual life had its own meaning, he had nothing to offer his children: like him they would end their lives six feet under the ground. He could neither stop them from dying nor give them a meaning to their lives that outlasted their death.

Heidegger said we should spend more time in graveyards. He believed that facing the inevitability of our death would make us live more authentic lives. No doubt he was right. But wouldn’t something else change how you lived your life? Namely, if you believed death was not the end?

There’s a point being made here that goes far beyond immortality: it is about the restoration of life by the author of life who defeated death.

The Christian tradition is founded on an event with a unique promise. Christians claim that Jesus defeated death by dying and rising again. This means that even though we still die we will one day rise with him and never die again. There is no greater hope on offer. Nothing could be more relevant, more urgent, more meaningful than this central Christian claim. It is equally relevant to someone gasping for breath on a sinking ship and to someone bursting with health in the prime of life.

If Heidegger is right, the Christian message strikes at the heart of the most horrifying and cold reality of the human condition. The event of the Resurrection has the power to transform every anxious future-oriented human being facing their inevitable death. The reality is cold and horrifying no more. Jesus’ death broke the curse of death and robbed it of its power. If we follow him in dying, we will also follow him in rising. Just as Jesus rose again (and because Jesus rose again), we will rise again one day and death will be no more.

But is the Christian claim really unique? Don’t other religions believe in life after death?

Not like this. Not bodily resurrection. We must not confuse the Christian claim with a general belief in immortality, though that is an essential part of it. Other religions hold that our souls continue after death. Some teach reincarnation, an endless cycle of birth and death. But there’s something more to the Christian claim. The Gospel accounts tell that Jesus died and was buried in a tomb. If all Jesus wanted to prove was that the spirit outlives the body, then his body could have remained in the tomb. No big deal: it’s just a dead body. His ghost could have still wandered around and appeared to people.

All four Gospel accounts begin their scandalous news with the inability to find Jesus’ dead body. Three days after he dies, the women go to his tomb, and the tomb is empty. When the risen Jesus appears to the disciples, he takes pains to prove he is not a ghost. He invites them to touch him. He eats breakfast with them. He walks among them as flesh-and-blood. There’s a point being made here that goes far beyond immortality: it is about the restoration of life by the author of life who defeated death.

That’s why the Christian teaching on immortality is unique: because immortality is just the beginning. It’s about far more than that. It’s about restoration to life in the world God made: the bodily world in which we live. God created it. He doesn’t want us to leave it after we die. He wants us still to live in it. Jesus’ death empowered us so that we can live in it forever.

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.
