What Did God Have in Mind? Antoine Arnauld and the Puzzle of Why Bad Things Happen

Imagine you’re building a sandcastle. You have a perfect vision of what it could be—towers, a moat, a drawbridge. You have all the sand and water you need. And you’re the best sandcastle builder in the world. Nothing could stop you from building the most amazing sandcastle ever.

But you don’t. You build something just okay. It’s a little lopsided. The moat fills with muddy water. Part of it collapses. Anyone watching would say, “Wait—why didn’t you build it better? You could have.”

That’s a strange question. But it’s the same question that philosophers have asked about God for centuries. If God is all-powerful and all-good, why didn’t God make a better world? Why is there suffering? Why do bad things happen to good people? And—for a particular group of thinkers in the 1600s—why aren’t more people saved?

This last question might sound weird if you’re not used to thinking about it. But imagine sitting in a room with people who believe that God wants everyone to be happy with God forever. Now look around. Not everyone believes that. Not everyone lives that way. Some people seem to reject it completely. Does that mean God failed? Or does God not actually want everyone to be saved?

A French philosopher named Antoine Arnauld (said “Ar-NO”) spent his whole adult life tangled up in questions like these. He was a brilliant, fierce debater who got kicked out of the University of Paris for defending ideas the Church didn’t like. He argued with everyone—other philosophers, theologians, even his friends. And at the center of all his arguments was a single, stubborn question: What kind of being is God, and how should we talk about God?

How Do You Talk About Something You Can’t Fully Understand?

Arnauld had a simple rule: there are two ways to know things, and you shouldn’t mix them up.

One way is philosophy. In philosophy, you use reason. You think carefully, you argue logically, and you try to figure things out with your own mind. The other way is theology. In theology, you start with what God has revealed—through sacred writings, through religious tradition—and you defend those truths.

The problem, Arnauld thought, was that people kept confusing the two. They’d take a philosophical idea and pretend it came from God. Or they’d take a religious belief and try to prove it with logic, when it couldn’t be proven. He called this a dangerous mess.

His biggest target was another philosopher named Nicolas Malebranche (said “mal-BRONSH”). Malebranche was also a brilliant thinker, and he and Arnauld had once been friends. But then Malebranche published a book called Treatise on Nature and Grace, and Arnauld got furious.

Why? Because Malebranche tried to explain why God doesn’t save everyone—and Arnauld thought his explanation made God sound like a human being.

The Car-Buying God

Here’s what Malebranche said, in simple terms.

God wants everyone to be saved. But God also wants to act in the simplest, most elegant way—like a master craftsman who doesn’t use complicated tools when simple ones will do. And here’s the thing: if God tried to save everyone individually, that would require a lot of special, one-off actions. It would be messy. It would be like building a new sandcastle for every single person.

Instead, God sets up general laws—like the laws of nature—and lets those laws play out. Some people get saved, some don’t, depending on how the laws happen to work. God could intervene to save more people, but that would mean using particular, special actions, which would be less elegant. And God’s wisdom won’t let Him do that.

Malebranche gave an analogy that might help. Imagine you’re buying a car. The best car costs $50,000. But there’s a second-best car for $20,000. If you buy the best car, you can’t afford anything else. If you buy the second-best, you have money left over. Which is the smarter choice? Probably the second-best car.

In the same way, Malebranche argued, God chooses a world that isn’t the best possible but is the best combination of goodness and simplicity. If God made a world where everyone was saved, that would be like buying the most expensive car—but God would have to act in complicated, unworthy ways to make it happen. So God chooses a simpler approach and accepts that some people won’t be saved.

Arnauld thought this was not just wrong, but insulting to God.

Does God “Consult” His Wisdom?

Arnauld’s central objection was this: Malebranche talks about God as if God were a human being making decisions.

Malebranche says things like “God consults His wisdom before acting.” He says God “chooses” the simplest ways. He says God “wills” to save everyone but “cannot” because His wisdom stops Him.

Arnauld pounced on this language. “As if God needed to consult His wisdom so that what He wills should be wise!” he wrote. “As if His will were not His wisdom!”

Think about it this way. When you decide something, you have to think about it first. You weigh options. You consider what’s possible. You might change your mind. That’s because your will and your understanding are separate things—you can know something is good but not want to do it, or want something without knowing how to get it.

But for God, Arnauld insisted, that’s not how it works. In God, will and wisdom are the same thing. God doesn’t have to think about what’s wise and then decide to do it. Whatever God wills is wise, simply because God wills it. To imagine God “consulting” His wisdom is to imagine God as a very powerful human being, not as God.

This might sound like Arnauld is just nitpicking about words. But he thought the stakes were enormous. If you start talking about God as if God were a person, you end up with a God who is limited, who has to compromise, who can’t get what He wants. And that, Arnauld believed, was not the God of Christianity. It was a made-up God, a human invention.

The Puzzle of Grace and Freedom

There’s a deeper problem here, and it shows why Arnauld was such a complicated thinker. He believed two things that seemed to pull in opposite directions:

God’s grace (help) is irresistible. When God decides to save someone, it happens. No one can resist God’s will.
People are free. If someone does something good and gets saved, they deserve credit for choosing freely.

So which is it? If God makes you do something, how can you be free? And if you’re free, how can God’s will be irresistible?

This puzzle has bothered philosophers and theologians for centuries. Arnauld’s solution was both clever and humble.

He said: We know from scripture and tradition that grace is irresistible. And we know from our own experience that we are free. Both are true. We just can’t fully understand how they fit together.

“But that’s cheating!” you might say. “You can’t just say ‘both are true’ and stop thinking.”

Arnauld would agree that it’s frustrating. But he thought the frustration was honest. God, he said, “dwells in inaccessible light”—meaning we can’t see into God’s mind. We can know that God saves people freely and that people are free, but we can’t know how that works. To pretend we could explain it would be to make God small enough for our minds to grasp. And that, Arnauld thought, was the real mistake.

How to Think About a Perfect Being

At the end of his life, Arnauld was still arguing about these questions. He wrote a short treatise on free will, defending the idea that freedom means having “the power to do otherwise.” If you couldn’t have chosen differently, you weren’t really free. That sounds straightforward. But the puzzle remained: how can God’s grace be irresistible and leave people free to choose differently?

Arnauld’s answer was basically: “I don’t know, but I know it’s true.”

Some philosophers today find this unsatisfying. Others find it deeply honest. Arnauld wasn’t trying to explain everything. He was trying to say: when you’re talking about something as big as God, you have to be careful not to shrink it down to human size.

Maybe that’s the most important thing Arnauld has to teach us. When we try to understand difficult questions—about why bad things happen, about whether we’re really free, about what God is like—we can be tempted to make the answer too simple. We can say, “Oh, it’s just like when a human being makes a choice.” Or, “God is just like a really powerful parent.”

Arnauld would say: stop. The thing you’re trying to understand might be bigger than that. The honest thing to do is to say what you know, admit what you don’t know, and refuse to pretend you understand what you don’t.

That’s a hard discipline. But maybe it’s the only way to avoid making the universe smaller than it really is.

Key People

Antoine Arnauld (1612–1694) – A French philosopher and theologian, so fierce in debate that people called him “the Great Arnauld.” He argued that God’s actions can’t be understood by comparing them to human choices.
Nicolas Malebranche (1638–1715) – A French philosopher and priest who argued that God always acts in the simplest way, even if that means not saving everyone. Arnauld thought he made God sound too human.
René Descartes (1596–1650) – The famous French philosopher (“I think, therefore I am”) whose ideas about mind and body Arnauld defended but also modified in important ways.
Thomas Aquinas (1225–1274) – A medieval philosopher and theologian whose writings Arnauld used as ammunition against Malebranche, especially on the topic of free will and God’s nature.

Things to Think About

If you believed God was all-powerful and all-good, how would you explain why bad things happen? Are you satisfied with your explanation? What would Arnauld say about it?
Arnauld said we shouldn’t talk about God as if God were a human. But if we can’t use human concepts to understand God, how can we talk about God at all? Is there a way to describe something that’s completely beyond human experience?
Do you think people can be free even if their choices are guaranteed to happen? For example, if your parents know you so well that they can predict exactly what you’ll choose in a situation, are you still making a free choice? What if God knows?
Arnauld said we should admit when we don’t understand something, rather than pretending we do. Is that always the right approach? Are there times when we need to push for an explanation even if it’s hard?

Where This Shows Up

The problem of evil (why bad things happen if God exists) is still a major topic in philosophy and religion today. You’ll hear versions of it in debates between believers and atheists.
Free will vs. determinism is debated in courtrooms (are criminals responsible for their actions if their brains made them do it?), in psychology (is personality fixed?), and in everyday life (can people really change?).
The idea that we shouldn’t anthropomorphize things shows up in debates about artificial intelligence (is AI actually thinking, or are we just imagining it thinks like us?) and about animals (do animals feel things the same way humans do?).
Philosophers still argue about “divine hiddenness” – if God exists and wants us to know Him, why is it so hard to be sure? This is basically the same puzzle Arnauld wrestled with, just in different words.
