How Shakespeare seasoned justice with mercy

As Shakespeare’s birthday approaches, Anthony Baker explores how the playwright let two ancient enemies fight it out on stage – justice and mercy.

In order to act with mercy toward someone, must I forgo a sense of justice? If I decide to act justly, have I decided to leave mercy behind? These are questions of philosophers and theologians. They also provide some of the thickest philosophical and theological ponderings of William Shakespeare.  

A studied contemplation of mercy and justice does not, of course, originate with the Elizabethan playwright. For as long as humans have pondered how to order their civic spaces, they have puzzled over the demands of each. Around 500 B.C.E, Rabbi Yehudah is recorded as having said that God spends three hours a day on a throne of justice before getting up and crossing over to a throne of mercy, on which he spends an equal length of each day. 200 years later, when Plato devoted his most famous dialogue to the question of justice, he gave only the slightest nod to mercy, acknowledging that the just ruler would need a reputation for generosity.  

Though many of Shakespeare's plays notice the interaction, or lack of interaction, of these two qualities (The Tempest and nearly all of the history plays, for instance), he penned two for what seems to me the explicit purpose of letting these two ancient enemies fight it out on stage. I'll focus on one of these and return briefly below to the other.  

Justice Unbound 

The first, Measure for Measure, takes its title from a line from Jesus' sermon on the mount. This is a signature move of the Bard, to take a religiously charged line, doctrine, or even person, and make theater out of them. While some have argued that this was all he was doing with religion or theology, I have suggested that he is doing more. He is mining the depths of faith language to see if he can find gems that we might be missing if we only pay attention to the identity politics of Reformation era England. "Grace is grace despite of all controversy," one character in this play says. That could be the tagline for Shakespeare's theological interventions.  

We see Shakespeare having some of his typical fun with religion in Measure for Measure. The Duke of Vienna gives away his power in order to go abroad, as he claims, for a piece of international politics. In fact, he sneaks back into the city immediately, now disguised as a friar (a member of a religious order like the Franciscans). He tells the friar who lends him the robes that he is doing this because he has made an irresponsible practice of letting the city's "strict laws and biting statues slip." He has, that is to say, been more of a merciful father than a just ruler. He doesn't want to unbind this "tied-up justice" himself, since he fears this would cause his people to question his integrity. ("But you've always been so merciful before now!") So, he contrives a plan to deputize one of the nobles, Lord Angelo, to be the hammer of justice in his stead. He also hints that there are other reasons for his disguise. I'll come back to that bit of foreshadowing.  

Angelo immediately finds an episode in need of his firm hand. A gentleman named Claudio has got his girlfriend, Julietta, pregnant. There are in fact circumstances that seem worth considering: the two are engaged and are only waiting for her to receive her dowry - arranged before they go to church.  But Angelo will not hear of clemency. He is severe, one noble remarks. This is as it should be, a wise old Lord responds. "Mercy is not mercy that oft looks so," he says, perhaps angling gently at a critique of the Duke's mode of operation.  

Justice only deals with what it can see, in other words. We pick up a jewel on the ground only when it catches the light; buried or soiled, we walk right past it or even trample it.

Merciless Secrets 

At this point in the play we have our two adversarial qualities in neat, separate containers. One container, called The Duke, is only merciful. But this container must be removed from the state so the other, called Angelo, can display its contents of merciless justice. 

But, as this is Shakespeare, things quickly begin to get messy. Angelo turns out to be hiding secrets. The old Lord, having hinted that the Duke is over-merciful, now suggests that Angelo is being a bit hard on Claudio. He cautiously suggests that, had time and place given opportunity, Angelo himself might have come to the wrong side of the law. Angelo's response says more, perhaps, than he means to:  

"What's open made to justice,/ That justice seizes."  

Justice only deals with what it can see, in other words. We pick up a jewel on the ground only when it catches the light; buried or soiled, we walk right past it or even trample it.  

This is our first hint of Shakespeare's subversion of the polarized containers. Listening to Antonio's speech, we've begun to wonder if, lacking the slightest trace of mercy, justice doesn't in fact begin to look a little unfair. 

And then we see Angelo acting on his theory. Claudio's sister comes to him to beg for her brother's life. Angelo is quickly captivated by her beauty, and soon offers her a deal. If she will meet him for sex in the garden—secretly of course, so that the crime cannot be "unjust"— he will let Claudio free.  

This offer obviously shows the rot in his theory of justice, as he is forming a contract, a just bond, around blackmail and rape. But it also ruins mercy, since his proposed pardon of Claudio is not merciful at all, but simply the meeting one end of a "just" bargain.  

The Kiss 

Our neat containers have nearly dissolved around their contents. "Mercy is not mercy that oft looks so," but justice is not justice that only looks so. Justice as merciless as Angelo's turns out to be unjust, in the same way that mercy without justice turns up bereft of mercy. This is why the Duke left, and it's why Angelo fails as his deputy.  

But the Duke has returned, and now we begin to see what his secret purposes are. He goes to visit Claudio for confession and counsel, and also goes to Claudio's sister for comfort and advice. Here is one of the delightful places where Shakespeare plays with religious stereotypes.  The "controversy" of grace that I mentioned above, is for Shakespeare's audience an all-too familiar one, over whether God saves us through our works, and so through a contractual justice, or through grace, which is to say through an act of unearned mercy. The Catholic Church was generally (though not often accurately) associated with the former, the Protestants with the latter. But here it's a Catholic friar (or at least a disguised one!) who enters as the personified mercy.  

The Duke/friar devises a plan, and it nearly goes as awry as the more famous friar's plan in Romeo and Juliet. Which is to say that our comedy nearly becomes a tragedy. I won't give away the ending, if you've forgotten or never made it through. But I'll offer a hint: the Duke, on his return, is no longer an embodiment of unjust mercy as he was before. Now he sees clearly that true mercy is just, and true justice is mercy. The two must kiss, as the Psalm puts it. His clever idea for a resolution is all about allowing mercy and justice to exchange a kiss. 

When Mercy Seasons Justice 

The more familiar play in which Shakespeare lets us watch the battle of justice and mercy is The Merchant of Venice. Here we find the story of maybe the strangest contract made since the dawn of commerce: if a merchant defaults on his loan, the moneylender will claim an entitlement to "a pound of flesh." Is this mutually agreed-upon contract unjust, or simply merciless?  

The religious fun is rampant in this play as well. The lender is a Jew and the merchant is a Christian. But the Jew's strict call for commercial exactitude gets tempered by his excessive love for his daughter, and the Christian's supposed reputation for grace is in fact an excuse to practice favoritism. Eventually we have on stage such a confusion of religious stereotypes that someone asks which character is which.  

Well, the poor merchant can't pay, as we knew already at the moment he made the foolish contract. And so, Portia, this play's mercy persona, comes—also in disguise—from the fairytale land of Belmont with a clever trick to save her beloved merchant. While her solution involves a highly questionable interpretation of the law, she manages to persuade the ruling authority.  

As Portia is making her case, she offers one of the most explicitly theological speeches in all of Shakespeare's works. Earth's rulers might think they are most godlike when they enact the law with authority, she says. But "mercy is above this sceptered sway." In fact, mercy is "an attribute of God himself." She concludes, much as the Duke concludes, that "earthly power doth then show likest God's/ When mercy seasons justice."  

In plays like these we see displayed one of his most enduring gifts to us: the ability to play with the familiar and make it strange and new.

Shakespeare, had he indeed been "for all time" as a contemporary put it, would be celebrating his own 459th birthday this week. In plays like these we see displayed one of his most enduring gifts to us: the ability to play with the familiar and make it strange and new. He gives us philosophical and religious figures and themes, and then just as we assume we know who and what they are, he surprises us by showing what sort of dish you can make if you but swirl the ingredients.  

Our best efforts at justice, whether of the personal or political sort, must be seasoned by mercy. Our acts of mercy, if not ultimately just acts, will turn out to be merciless. Would we have noticed this if no one had had let it happen on stage in front of us?

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.
