Real time

One Sunday time warped. Oliver Wright explores the conception of real time.

After 15 years as a lawyer in London, Oliver is currently doing a DPhil at the University of Oxford.

“Time’s going really slowly today!” 

“Golly – where’s that week gone?” 

“It felt like time stood still for a moment…” 

“Sorry, I lost track of the time.”

These expressions are common enough to be cliché. I’ve used each of them in the last few weeks. But do they actually make any sense? We all know that time is in seconds, minutes, days, weeks… very reliable, very constant, very scientific. We all know that time doesn’t stand still – how can it?! We know that, don’t we?  

But us modern, scientific cultures can often forget how recent these regimental patterns are. Of course, people and cultures have been measuring time for millennia – Ancient Egyptian sundials, early Medieval monks needing to fit in seven services a day. But time, even in those examples, always said more than just ‘keeping time’… a sundial was especially meaningful in a world where it usually shone every day, and was itself held up as a God; for life in a monastery, worship was the time-keeping device, worship was the rhythm of life.  

Time, and particularly our experience of it, doesn’t easily track onto our clocks. We are constantly experiencing time quickly, slowly, forgetfully, meaningfully. Could there be another account of time, not one governed by the Greenwich Meridian, which is – somehow – more real?  

The Ancient people of Israel were some of the first to realise that there is more to life than clock-watching. It’s hard for us to imagine how revolutionary the idea of a Sabbath is. But when it became the norm for the Jews to observe the Sabbath every seventh day – to keep it holy – this wasn’t just about being religious. This was about justice and the avoidance of exploitation. In a world where slaves and workers in the field were expected to work every single day, the idea that there should be rest and restoration said something distinctive both about the nature of work, and about the nature of what it is to be human. And it also said something distinctive about hope.  

For Christians, hope and the Sabbath are forever now held together in the story of Jesus’ resurrection – the very first Easter day. There’s much that could be said about this. But for our little topic of time, it’s quite explosive. The people of Israel had believed (we think) that death would be defeated by the return of God to his people at the end of time. But here was God – in the flesh – defeating death… and time is still marching on! What are we to make of this?  

Something of the end has come in the middle. Time is now warped.

 

Well, one of many things is that, when Christians confess their belief that ‘on the third day Jesus Christ rose again from the dead’, they are saying that something of God’s ultimate future, his promise one day to be with us forever, what the Sabbath had always pointed towards like a signpost, had now happened once and for all. Something of the end has come in the middle. Time is now warped.  

One of the first signs of this ‘warping’, was another day off. The early Christians by and large slotted into the ongoing Jewish observance of Sabbath. But then – treating it as the start of their week – they observed a second day off, a day of feasting and celebrating, and marching through the towns waving banners. The Lord’s day. Resurrection day. Day one – starting all over again, starting afresh, making something new out of the old.  

A second sign was this. Time held a new power – a new potency if you like. It wasn’t that the days had somehow changed duration, or our lifespans were altered. No – Christians think that there is a new expectancy in the air. They are to live, Paul writes, as if the fixtures which hold them to this world now no longer hold the same power. ‘Time is contracted’ he goes on (not ‘shortened’ as it’s sometimes translated) – ready to pounce like a cat.  

The third sign follows from the second. The Christian experience of time is constantly pulling backwards and forwards. In celebrations and worship, Christians look back and recite God’s mighty deeds from the past. In reciting them in the present, they re-present them. But the point of ‘re-presenting’ these mighty acts was not just to bring comfort to the present; it also reinvigorated hope for the future. Christians – as the Creed goes on – ‘look for his coming again’. The experience of time for a Christian (or, even, a philosophy of history) is not governed by a flat-line Hegelian aufhebung – that every day, every hour succeeds its predecessor. Instead, the past and the future works on the present in a constant swell of recall and expectation.  

Christians see their lives held by God’s time. They’re not a clock-watching, ‘progress-reliant’ people. In the resurrection, Christians believe that God has changed the way we view time once and for all. On that, all their hope is founded.  

That’s real time.

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.
