The distinction between technology and human beings has become blurry: AI seems to be able to listen, answer our questions, even respond to our feelings. It becomes increasingly easy to confuse machines with humans. In this situation, it is increasingly important to ask: What makes us human, in distinction from machines? There are many answers to this question, but for now I would like to focus on just one aspect of what I think is distinctively human: As human beings, we live and learn in time.

To be human means to be intrinsically temporal. We live in time and are oriented towards a future good. We are learning animals, and our learning is bound up with the taking of time. When we learn to know or to do something, we necessarily make mistakes, and we take practice. But keeping in view something we desire – a future good – we keep going.

Let’s take the example of language. We acquire language in community over time. Toddlers make all sorts of hilarious mistakes when they first try to talk, and it takes them a long time even to get single words right, let alone to try and form sentences. But they keep trying, and they eventually learn. The same goes with love: Knowing how to love our family or our neighbours near and far is not something we are good at instantly. It is not the sort of learning where you absorb a piece of information and then you ‘get’ it. No, we learn it over time, we imitate others, we practice and even when we have learned, in the abstract, what it is to be loving, we keep getting it wrong.

This, too, is part of what it means to be human: to make mistakes. Not the sort of mistakes machines make, when they classify some information wrongly, for instance, but the very human mistake of falling short of your own ideal. Of striving towards something you desire – happiness, in the broadest of terms – and yet falling short, in your actions, of that very goal. But there’s another very human thing right here: Human beings can also change. They – we – can have a change of heart, be transformed, and at some point in time, actually start to do the right thing – even against all the odds. Statistics of past behaviours, do not always correctly predict future outcomes. Part of being human means that we can be transformed.

Transformation sometimes comes suddenly, when an overwhelming, awe-inspiring experience changes somebody’s life as by a bolt of lightning. Much more commonly, though, such transformation takes time. Through taking up small practices, we can form new habits, gradually acquire virtue, and do the right thing more often than not. This is so human: We are anything but perfect. As Christians would say: We have a tendency to entangle ourselves in the mess of sin and guilt. But we also bear the image of the Holy One who made us, and by the grace and favour of that One, we are not forever stuck in the mess. We are redeemed: are given the strength to keep trying, despite the mistakes we make, and given the grace to acquire virtue and become better people over time. All of this to say that being human means to live in time, and to learn in time.

So, this is a real difference between human beings and machines: Human beings can, and do strive toward a future good.

Now compare this to the most complex of machines. We say that AI is able to “learn”. But what does it mean to learn, for AI? Machine learning is usually categorized into supervised learning, unsupervised and self-supervised learning. Supervised learning means that a model is trained for a specific task based on correctly labelled data. For instance, if a model is to predict whether a mammogram image contains a cancerous tumour, it is given many example images which are correctly classed as ‘contains cancer’ or ‘does not contain cancer’. That way, it is “taught” to recognise cancer in unlabelled mammograms. Unsupervised learning is different. Here, the system looks for patterns in the dataset it is given. It clusters and groups data without relying on predefined labels. Self-supervised learning uses both methods: Here, the system uses parts of the data itself as a kind of label – such as, for instance, predicting the upper half of an image from its lower half, or the next word in a given text. This is the predominant paradigm for how contemporary large-scale AI models “learn”.

In each case, AI’s learning is necessarily based on data sets. Learning happens with reference to pre-given data, and in that sense with reference to the past. It may look like such models can consider the future, and have future goals, but only insofar as they have picked up patterns in past data, which they use to predict future patterns – as if the future was nothing but a repetition of the past.

So this is a real difference between human beings and machines: Human beings can, and do strive toward a future good. Machines, by contrast, are always oriented towards the past of the data that was fed to them. Human beings are intrinsically temporal beings, whereas machines are defined by temporality only in a very limited sense: it takes time to upload data, and for the data to be processed, for instance. Time, for machines, is nothing but an extension of the past, whereas for human beings, it is an invitation to and the possibility for being transformed for the sake of a future good. We, human beings, are intrinsically temporal, living in time towards a future good – which machines do not.

In the face of new technologies we need a sharpened sense for the strange and awe-inspiring species that is the human race, and cultivate a new sense of wonder about humanity itself.

Budgeting for discontent

The Chancellor can't please everyone, but is contentment possible?

As the Chancellor Rachel Reeves seeks to raise billions in this Autumn budget, the news media are all over the downsides. Poor pensioners freezing during winter and businesses complaining of the tax burden are political headlines. Tough choices must be made, but we are rarely happy when it comes to money.

Economic discontent is ironically a cultural norm in first world countries. In the west we have become used to what psychologists call the hedonic treadmill – adjusting our expectations to any new benefits and finding ourselves wanting even more, to try to maintain the same level of happiness. It’s a mentality that dooms us to discontent. Socrates said, ‘He who is not contented with what he has, would not be contented with what he would like to have.’

Contentment seems to be a forgotten virtue today, and increasingly elusive in a society striving for happiness through wealth. Yet being content in life is a more valuable form of wealth than money. There is something enormously attractive about a tranquil state of mind and heart. Contentment does not mean passive acquiescence; there is a noble side to being passionately discontented about something that is unjust – especially when we are fighting for others. William Wilberforce demonstrated that with his campaign for the repeal of laws allowing slavery.

Our personal challenge is to be content in ourselves, whatever the circumstances. Oscar Wilde said, ‘True contentment is not having everything, but being satisfied with everything you have.’ Practising paying attention to what we do have and being thankful for it. That attitude of gratitude is a recognised way to lift our mood and strengthen our resilience. But thankfulness doesn’t solve every problem. Warm words may help warm hearts, but they don’t heat cold homes. Although gratitude is proven to improve our wellbeing, it’s not enough to compensate for all the problems of life. Because here’s the deal; life is tough and then you die, and there are many worse things than economic woes.

Pain, grief and loss are all too common, and they can test our resilience beyond what feels like our ability to endure. Chronic physical or mental illness for example; or being permanently disabled. Or the life-sapping effort to parent children with special needs; or caring for a parent/partner with dementia - especially when it goes on and on. Sometimes horrible events happen like violent abuse, or the deep grief of relationship breakdown or bereavement. This level of suffering pushes us to the end of ourselves, to the place where something more than psychological self-help is needed. What is the secret of contentment then?

I don’t envy the Chancellor, and I do not trivialise the very real challenges raised by having to make tough economic choices.

This is where the secular and the Christian worldview are radically different. Secular philosophers call people to show their own self-sufficiency and superior reason when enduring suffering. This can feel principled and stoic, but it lacks empathy and hope. Christianity accepts the reality of our own weakness and insufficiency, recognising that we can’t fix everything ourselves. Instead of trusting in humanity, we choose to trust God both for this life and the life to come. And this trust and hope is linked to a deeper form of contentment, which transcends pure rationality.

Of course, sceptics say this is just psychological comfort from an imaginary friend, and it doesn’t make sense, because surely any good God would not allow us to suffer in the first place. But any realist must acknowledge that a lot of human suffering comes from the damaging exercise of our own free will. Wars and slavery are examples. If God were to override our free will, we would be robbed of the authentic capacity to love, which makes us fully human. The coexistence of free will, suffering and God is a complex issue.

The experience of millions of Christ followers is that trusting God is much more than imaginary comfort. God is real and prayer changes things; the most ordinary, natural and chance experiences can be affected by it. And prayer changes us. In our vulnerability, if we choose to trust God something changes, we begin to relax, things become a bit easier to bear. In fact, the apostle Paul claimed that Christ’s power was perfected in his own weakness.

Contentment is a strange peace that comes from trusting God in the middle of difficult circumstances. One of the great old hymns was written by a man who lost his four daughters in an accident at sea, and also lost all his money in a fire. The refrain says, ‘It is well, it is well with my soul.’ This isn’t denial or delusion, it is the inner sense of quietness that God can give. Only an eternal perspective allows for that kind of contentment.

I don’t envy the Chancellor, and I do not trivialise the very real challenges raised by having to make tough economic choices. Britain is clearly in a place where some stringent fiscal discipline is needed, and that will inevitably cause some hardship and difficulties. But in the face of all the discontent that is so freely shared in the news, there is another way to respond. Instead of complaining about our flawed Government or moaning about our circumstances, we can change our perspective to put our trust in the ultimate Authority. And in doing so can find a peace that the world cannot give. Contentment is a treasure beyond the wealth of nations.
