It's our mistakes that make us human

What we learn distinguishes us from tech.

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.

When indulgence and inhibition are on the menu

As the time of feasting concludes, and resolutions start to crumble, Ryan Gilfeather takes some lessons on how and when to say 'no more'.

Advent and Christmas are heroic culinary seasons. They are times of abundant feasting on foods from rich and varied traditions. However, despite the enthusiasm many of us share in this overindulgence, we are, as a society, fairly ambivalent about the pleasures of food. 

Recently, Tim Hayward wrote a vigorous defence of gluttony, claiming that the Church labelling it a sin, because it defied the practice of self-denial in hope of future reward that he claims the Christian faith is predicated upon. Here, Tim represents a prominent belief in our culture, that taking pleasure in an activity cannot be wrong if it doesn’t have negative consequences on others.  

However, despite the prominence of these views, diet culture is still powerful and pervasive. Many of us, perhaps guilt ridden and ashamed, will resolve in the New Year to cut out the pleasures of food in order to drop a few waist sizes.  

This encouragement to say no to the pleasures of food, is an invitation to learn the habit of denying our inner yearnings, if they will lead to emptiness.

Over the years, Christians have also toyed with the question of what pleasure we are to take in food. They are certainly far more cautious than the hedonists among us would like. However, they give us a way to navigate between the Scylla of unrestrained indulgence and the Charybdis of starving ourselves entirely.  

Gregory of Nyssa, a Fourth Century bishop and theologian, argued that indulging the desire for the pleasures of food can replace our pursuit of those things which are truly good in life. Here, Gregory makes a similar point to Graham Tomlin in a recent article for Seen & Unseen. Gregory gives particular insight into the psychological experience of addiction to physical pleasure. In his biography of Moses, he likens the pursuit of physical pleasures to an enslaved person making bricks. The brick maker is entirely consumed, both in mind and body, with filling the brick cast and baking it. But, as soon as the brick is finished, the cast is empty again, and the process must be repeated. We dedicate our thoughts and our actions to achieving physical pleasures, but as soon as we attain them, they disappear. It is a futile process.  

Crucially, some people develop a kind of addiction to pursuing pleasure, they are stuck in the loop of dedicating their minds and bodies to achieving it again and again. They begin to experience emotional turbulence if they can’t attain pleasure, like anger, greed, or anxiety. This pattern of behaviour absorbs these people’s thoughts so much that it replaces their capacity to pursue those things in life which will truly make them flourish. Therefore, this encouragement to say no to the pleasures of food, is an invitation to learn the habit of denying our inner yearnings, if they will lead to emptiness.  

The most salient and pervasive examples of this today are digital content and social media. We tend to think of addiction in clinical terms, an extreme form of behaviour associated with people whose habitual consumption of drugs, alcohol, or gambling has run their lives off of the track. However, some psychologists argue for a broader definition of addiction. One which includes the habituation to compulsively consuming social media, the news, and other forms of digital media. For many of us, our compulsion to consume these kinds of content will occupy a great deal of our time and energy, which we could otherwise spend on activities which would make us thrive. Such as nurturing our relationships with God and with others, creative endeavours, and spending time in nature.  

A well-crafted meal, especially one received from a long culinary tradition, reveals the power of human creativity, which in turn shows us a glimmer of God’s creative act. 

Importantly, Gregory does not suggest that we ought to starve ourselves. A key aspect of learning to say no to the pleasures of food, is learning to say yes to that which our body needs. He explains that our minds are capable of determining how much is sufficient, but our inner yearnings are not. If they are left unchecked, they will cause us to desire to never stop eating. For those of us who are privileged enough to afford it, the solution is to neither punish nor destroy our bodies, but simply to stop when we have had a sufficient amount. 

Admittedly, this vision of eating does not sound like much fun. Food and wine certainly afford me great pleasure, not so much in their quantities but in their qualities; what room is there for people like me in Gregory’s vision of the kingdom of God? 

In his interpretation of the Song of Songs, a book in the Hebrew Bible, Gregory discusses two kinds of pleasure. He says that there are pleasures of the body, which, as discussed, consume our minds and bodies, replace our pursuit of those things which will help us truly flourish and give us turbulent emotions. However, there are also spiritual pleasures. These are experiences which lift our minds up to God and give us a kind of spiritual ecstasy. Although Gregory does not make this connection, I suggest that food can afford us these spiritual pleasures. The occasional feast can point to the abundance of God’s generosity to us. Fine fresh fruit on a summer's day can teach us something about the goodness of God’s creation. A well-crafted meal, especially one received from a long culinary tradition, reveals the power of human creativity, which in turn shows us a glimmer of God’s creative act.  

In this way, Christians have a way of thinking about the pleasures of food which walks the narrow path between the pitfalls of unhealthy overindulgence and mutilation of the body. It is cautious about a pattern of life given over to the pursuit of pleasure instead of those things which will make us thrive. However, it recognises those times in which food can lift up our minds to the divine. So, this New Year, don’t resolve to starve yourself in pursuit of a certain waistline, and certainly don’t give up on discipline altogether. Instead, focus on moderation, and the capacity to say no to unhelpful desires. Let this discipline open up space in your life to say yes to those things which will make you truly flourish.
