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.

Here's why we need to keep democracy holy

It's much more than a utilitarian deal that benefits the most.

George is a visiting fellow at the London School of Economics and an Anglican priest.

One of the more ludicrous constitutional contributions of late has been the parliamentary petition, with well past two million signatures when I last looked, demanding another general election be called, because the Labour government, elected in July, has “gone back on the promises they laid out in the lead-up to the last election.” 

Prime minister Sir Keir Starmer has surprised precisely no one by saying that he won’t be calling one. And so we’ll move on. But, in passing, what is truly breathtaking is how little our democracy is understood and, apparently, how unseriously democracy in the west is now taken. If that sounds unduly censorious, I have a two-word response: Two million! 

Little time need be spent on demolishing the premise of this spurious petition, other than to wonder how many of those signatories would have appeared on one calling for, say, a fresh mandate after the coalition government of David Cameron and Nick Clegg (where is he now? Ah yes) performed a massive reverse-ferret on a manifesto pledge not to raise university tuition fees. 

Or how many of these same fearless electors believe the result of the Brexit referendum should be voided because of the lies of the Leave campaign, most notable the one painted on the side of Boris Johnson’s battle bus. But no – two million residual, self-righteous righties can only be mobilised against a Labour government. 

This event none the less raises valid questions about what our democracy is (and is not) and why we should want to protect or even cherish it. These questions become the more critical because there’s a tangible feeling of slippage in western democracy, as if we’re growing a bit tired and even contemptuous of it.  

There’s the ominous re-growth of nationalism across Europe. And not a few bien pensants – me included, to my shame – might admit to a feeling after Donald Trump’s re-election as US president that democracy is too important to be left to the people. 

Slightly more seriously, we need to ask ourselves what the qualities of democracy are that we should seek to defend. The first of these is, quite obviously, the rule of law. Should a political actor seek to overthrow a democratically established electoral process, then that is a crime within the rule of law. Witness the horrors on Capitol Hill in Washington DC on January 6 2021.  

That’s the Feast of the Epiphany as it happens, but nothing to do with the coming of wise men. With Trump at the centre of it. Draw your own democratic conclusions – and weep for the rule of law. 

Natural justice is to ensure that vexatious petitions don’t overthrow legally elected governments, either by lobby or violence. 

Again, why does this matter and what is it about democracy that we hold sacred, even holy? It can’t simply be that we hold dear a kind of hard utilitarian ideal that what we elect to do is for the benefit of most of the people, for most of the time, as decided by popular mandate among the demos. 

If we believe in democracy, as I believe most of us do, we’re presented with a choice: We can look to secularism as a solution, universal Enlightenment principles built on citizenship and equality before the law. Or we can look to a multiculturist model, keeping the peace between essentially separate communities and the state. 

Or we can shape something on Augustinian Christianity, that recognises the limits of political democracy, which would eschew undemocratic theocracy, but which would hold that no political order other than the Body of Christ (the Church) can claim divine authority. 

We’re in classic Rowan Williams theological territory here: “[T]he Body of Christ is not a political order on the same level as others, competing for control, but a community that signifies, that points to a possible healed human world.”   

Unsurprisingly, I buy that. Williams goes further to state this spiritual effect on the political environments in which we find ourselves is likely to be “sceptical and demystifying.” Which seems to be a reasonable manifesto in a democracy. 

The principle of election can be a worrying one in theological terms. We don’t “elect” God, though some secularists would claim that the Godhead is our invention. Rather, it has sometimes been perceived to be the other way around historically. 

Reformational Calvinism would hold, among many other things, the rather terrifying view that we’re elected by God. “The Elect” are those who will be saved, while the rest of us (I presume) can rot in hell. Little democracy there. 

Less deterministically, a more modernist worldview would argue that the Christian faith, on which foundation western civilisation is built, offers a viable moral definition of the lawful state, with which politicians of all (democratic) persuasions can tackle issues of global justice. 

One such issue of natural justice is to ensure that vexatious petitions don’t overthrow legally elected governments, either by lobby or violence. That’s an important aspect of Christian witness and will require true grit in in its application during the years ahead. That’s, if you will, our grit in the democratic oyster.
