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.

Anthony is a theology professor at Seminary of the Southwest in Austin, Texas.

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?

The quantum of leadership: how to flourish in science

Resolving the big questions - a conversation with Andrew Briggs, quantum technology pioneer.
A professor stands next to experimental equipment.
Andrew Briggs beside quantum research equipment.

Professor Andrew Briggs has been at the forefront of quantum technology for decades, pioneering the use of AI and machine learning in quantum computing. Two technologies that will shape our world. 

Andrew has been a leader in a demanding and cutting-edge academic field. In this interview the Oxford-based academic shares his insights on how to lead scientific endeavours and flourish in life. 

Pawel Puczkarski: We meet on Northmoor Road, which, more than any other street, embodies the spirit of Oxford. 

Michał Łuczewski: I sense here the presence of all souls. 

Andew Briggs: Indeed! The Tolkien family first lived at number 22 before moving next door to number 20. Just opposite, in the garden shed of number 27, is where Sir Martin Wood built the first magnets for what was to become Oxford Instruments. Another neighbour was Sir Roger Bannister, the first man to run a mile in under four minutes. 

MŁ: High culture, big business, top sports. What about science? 

AB: Just across the street, Sir Rudolf Peierls spent his final years. He transformed our understanding of nearly every application of quantum theory, including materials science and nuclear energy. Nearby, Erwin Schrödinger was living at number 12 when he received the news that he had won the Nobel Prize; he later moved to number 24. It was also here that he conceived his famous Schrödinger’s cat thought experiment, which illustrated the fundamental insight of quantum physics—that quantum objects can exist in two states at once. The inspiration for the fictitious cat—both dead and alive—was quite alive. Schrödinger’s own cat was allegedly called Milton 

MŁ: What is your main driver in your manifold leadership roles? 

AB: The desire to contribute. And pure curiosity. I am absolutely fascinated by big questions. 

PP: What’s the biggest question that remains for you unanswered? 

AB:  I suppose it might be, “How can I be more loving?”  

MŁ: That’s a big question, how about big answers? 

AB: One thing I’ve learned over time is the ability to live with unresolved big questions while maintaining the curiosity to understand them better. Take quantum physics. Among scientists, there’s still no agreement on what exactly happens during the act of measuring a quantum system. And measurement is the most basic thing we do in experimental science. So, are we being intellectually irresponsible? Now take prayer. I don’t think there’s consensus among people who pray about what exactly happens when they do. I certainly don’t yet have a fully satisfactory answer. But I long for better understanding. Quantum technologies have too much potential to walk away from the mystery. Likewise, prayer is too important to abandon simply because I don’t fully comprehend it. 

MŁ: What is your own understanding of prayer, then? 

AB: Prayer is about developing a relationship with God, just as conversation is part of building relationships with people. Of course, relationships involve more than conversation. But if you never talk to someone, you’re probably missing out on something. There are many ways to engage God. It is our love for God and our experience of His love. Being kind to people is part of our love relationship with God. 

MŁ: How come such a hard-nosed scientist like you speaks about God so openly? 

PP: It brings to mind a story that stretches across more than a century. In 1874, physicist James Clerk Maxwell founded the Cavendish Laboratory in Cambridge. Carved on its entrance doors, he placed a passage from Psalm 111 in Latin. 

AB: As the first Cavendish Professor, Maxwell personally oversaw every aspect of the lab's creation. He was a man of deep Christian faith.  

PP: Fast forward to 1973—you, as a young research student, proposed to the departmental committee carving the same quote in English above the entrance to the new Cavendish Laboratory: 'The works of the Lord are great, sought out of all them that have pleasure therein'

AB: To the Head of Department’s surprise, the committee not only did not reject my audacious idea, but they enthusiastically supported it.  

MŁ: Another half-century passed… 

AB: And that quote still serves as a motto for the next generation—it suggests that those inside the laboratory are discovering how God makes the world work, and that this pursuit is deeply joyful. Science is a God-given resource for faith and for the work of the Church. If the Church is here to serve the world, it must engage with the world as it is. For example, during the pandemic, scientific knowledge was essential in caring for people at risk. Conversely, faith offers wisdom and a voice in public discourse. 

MŁ: What does leadership personally mean for you? 

AB: Leadership, whatever its tools or styles, is ultimately about choosing what values to lead with. You can exercise leadership in many areas. Each of us does it in our own way, within our sphere of influence, using our unique talents. I'm distinguishing between the tools of leadership—whether oratory, intellect, money, or whatever—and the deeper question of which direction you want to lead. The real question is: What kind of leadership will you exercise? 

MŁ: Is that where my responsibility lies? 

AB: Yes, and to implement that responsibility using whatever talents and opportunities we have. If you're a professor at Oxford, you have to excel in your field. But Oxford is full of opportunities beyond academia, and I feel both a responsibility and a pleasure in engaging with the wider implications of my work. 

PP: You were deeply involved in the rapid development of quantum technologies and quantum information processing, within the evolving landscape of Oxford itself. We're no longer solely a research university. There's been a growing emphasis on scientific entrepreneurship and spinning out companies. 

AB: You're absolutely right–it's been a significant cultural shift at the university. In 2021, in my lab we realized that many people wanted to use our techniques, but we had reached the limit of our capacity to help others from our own resources. As academics, we love collaborating and helping, but we hadn’t even begun to meet the commercial need. So, we worked with Said Business School to conduct market research, which confirmed there was a viable market. That’s when we spun out the company, QuantrolOx. 

MŁ: In his recent book From Strength to Strength, Arthur Brooks argues that our careers will end much sooner than we expect and asks how we should prepare for that. It seems you’ve figured that out. You seem to go from strength to strength

AB: Arthur is a valued friend. He spoke at the U.S. launch of the Human Flourishing book in Harvard. And was kind enough to host the U.S. launch of Penultimate Curiosity, the book I co-authored with the eminent artist, Roger Wagner.  

PP: I see his painting behind us. 

AB: Yes, Roger used to have his studio in this house. As you might have noticed, Arthur has been lately placing more and more emphasis on the role of faith for human happiness. 

MŁ: Through his works, Brooks has been undergoing a kind of spiritual conversion. He makes it clear now that the goal of life is happiness and human flourishing, which starts with meaningful work, friends, family and most importantly - faith. For him personally means renewing his Catholic faith daily, moment by moment

AB: And he’s been speaking about that in a way that is completely genuine and comes from the heart. 

MŁ: I think there’s a similar kind of scholarly conversion in your life, where Christian renewal meets the Greek ideal of kalokagathia—the unity of the transcendentals, also reflected in your books. Penultimate Curiosity explores beauty. It Keeps Me Seeking explores truth. Citizenship in a Networked Age explores justice. And beauty, truth, and justice find their unity in your last book: Human Flourishing. How do you see your life? 

AB: I want to keep contributing for as long as I have the energy and the wherewithal. But life is nonlinear and stochastic. 

MŁ: Professor, pray elaborate! 

AB: We make choices and we are subject to events each of which could have been otherwise, and the consequences are often out of all proportion to the causal factors. Randomness is fundamental in quantum theory where the uncertainty is very mathematically rigorously described. I sometimes wonder if today’s rising generation struggles with stress because they expect too much control over their own destiny. 

MŁ: No doubt. 

AB: And that’s where Providence comes in. What traditional spiritual English calls Providence—from the same root as to provide—is, I believe, essential to making sense of a world that is both stochastic and nonlinear. This confidence in Providence, in the idea that we can navigate a world that is chaotic and still thrive, is profoundly important. If you look at the Gospels, when Jesus called people to follow him, they took a risk. They could have been wrong, following someone who was a spoof, but they made a decision—and it turned out to be a good one. And I think it's true of deciding to follow Jesus Christ. Could I be wrong? I suppose so. I don't think I am, but I could be. I don’t have certainty, but I choose. 
 
MŁ: And how do you know it? 

AB: Think of flying. You prepare as much as you can, but unexpected situations always arise. Air traffic control sometimes tells you what to do, but mostly, they ask what your intention is. You can’t hesitate when you're flying a plane. You can't just say, well, I'm not going to decide. That's not an option. You try to make them safe choices. You try to make them wise choices. But you have to make choices. Same with life. Thinking is good. But thought must lead to action. Some say I live my life by my transferable flying skills! 

MŁ: And your final destination? 

AB: Heaven, I hope. I believe this life isn’t all there is. I believe in a future with Trinity—Father, Son, and Holy Spirit—free from pain and suffering. The risk is to focus too much on going to heaven. I think the emphasis should actually be on the other direction: heaven coming to us. 'Thy Kingdom come!' That gives dignity to this world. 

MŁ: This conversation was a foretaste of a heavenly banquet! 

AB: More like Spanish tapas—small plates, not a grand feast. 

PP: A series of little courses? 

AB: Exactly. And when you write this up, make it look like there was a plan. 

MŁ: In your nonlinear, stochastic life, we’ve already found a hidden pattern. A kind of Da Vinci Code of Andrew Briggs. 

AB: And the code is…? 

PP: Have you ever thought about combining your book titles into a life motto? Imagine it inscribed over your Northmoor Road house: Penultimate Curiosity… Keeps Me Seeking… Human Flourishing

AB: Perfect! I love it. That’s my code.
