It’s been a year since last Passover, when I sat across from a 14-year-old boy—a friend of my son’s from Jewish day school—who had quietly stopped keeping kosher, stopped observing Shabbat, and decided, without telling his father, that his newfound atheism made Judaism irrelevant. He wasn’t angry. He wasn’t performing rebellion for an audience. He had simply concluded, with the calm rationality of a teenager who has discovered science and respects it, that the whole thing no longer made sense. He was walking away.

My own childhood in the suburbs of Maryland orbited around being Jewish. It was never a question, never a debate. It was the thing I knew in my bones to be essential, even before I could say why. So listening to this boy explain his indifference—politely, intelligently, without hostility—was disorienting. I recognized the honesty of it even as I felt its sting.

In the year that has passed between that Passover and this one, his words stayed with me in a way I hadn’t expected. They reawakened something I’d tried to work out a quarter century ago—a set of ideas about the connection between physical reality and the value of Jewish identity that I’d once tried to commit to paper. That earlier attempt came out reading like a long equation. Dry, inaccessible, lifeless. I put it away and moved on with my life. But this boy’s quiet indifference pulled the whole thing back to the surface, and this time I couldn’t let it go.

Not because his arguments were especially original—I’d heard versions of them all my life—but because I realized that nobody in his world had given him a reason to stay that he could actually respect. The adults around him had offered faith, which he’d lost. They’d offered guilt, which he resented. They’d offered nostalgia, which bored him. What nobody had offered was an argument that started from the ground he was actually standing on: the empirical, the observable, the real.

So I rewrote this idea from scratch. The result—a work I call The OR Axiom—is what I’ve spent this past year building.

This article is not that work. It is the question that made the work necessary.

He is not in the Haggadah, this boy. Every year at the seder we retell the Exodus story through the framework of Four Sons—the Wise, the Wicked, the Simple, and the One Who Does Not Know How to Ask. Each gets addressed in his own language. It is one of our tradition’s most elegant teaching devices: the story changes depending on who is at the table.

But there is a fifth son now, and the Haggadah has no page for him.

He is the one who leaves before the seder begins. Not out of malice. Not out of confusion. He leaves because the entire enterprise feels to him like an artifact of another era. He may be brilliant. He may be deeply ethical. But he does not see why being Jewish should matter more than being a good person who happens to have Jewish parents. And he is honest enough not to pretend otherwise.

I want to say something about this boy that may sound strange: he is not wrong to demand a reason. The tradition itself would not want him to accept something he doesn’t understand. The youngest child at the seder is commanded to ask. The people of Israel are named for a man who wrestled with God, not one who submitted in silence. If this boy says “I don’t see why this matters,” he is, in a way he doesn’t realize, acting out a deeply Jewish impulse—the refusal to take anything at face value, even his own heritage.

The failure is ours, not his. We have not given him a language he can hear.

Consider what we typically offer someone like him.

There is the argument from history: we have survived for 3,500 years, against odds that no historian can fully explain. That persistence must mean something. But survival alone is not an obligation. The fifth son can acknowledge an impressive track record without feeling personally bound by it.

There is the argument from achievement: the wildly disproportionate Jewish contribution to science, literature, medicine, and virtually every field of intellectual endeavor. It is a remarkable pattern, and it demands an explanation. But the fifth son will reasonably respond: “Fine. And I can contribute to all those fields without calling myself Jewish.”

There is the argument from solidarity: after October 7th, after watching the oldest hatred erupt with a savagery that shocked even those who thought they understood it, surely the least we owe our people is to stand with them. But the fifth son might hear this as a case against remaining Jewish. Why volunteer for a target that has been painted on our backs for three and a half millennia? If the identity invites such relentless persecution, isn’t the rational move to set it down?

And there is the argument from God: the covenant is binding, the commandments are real, the Creator chose this people for a mission. For the believing Jew, this settles everything. But for the fifth son, this is precisely the premise he has already abandoned. You cannot use the conclusion he disputes as the starting point for why he should accept it.

So what is left? What can you say to a person who has heard all of these and found each one, on its own terms, insufficient?

I am a physician. I have spent my career watching a very specific contest unfold inside human bodies: the contest between the intricate order of health and the disorder that disease imposes on it. Every diagnosis is a story about boundaries being breached. Every treatment is an attempt to restore a distinction that has broken down. Cancer, the disease I see perhaps most vividly through this lens, begins when a specialized cell—a cell that knows what it is—loses its identity and reverts to something generic, something primitive, something that no longer respects the borders of the tissues around it. The movement from differentiation toward sameness is, in the body, the very signature of destruction.

That pattern is not confined to medicine. It is the most fundamental tendency of the physical universe. Physics has a detailed vocabulary for it. We call it entropy—the Second Law of Thermodynamics—and it governs everything from the cooling of stars to the decay of civilizations. But what physics has been considerably less interested in doing is naming the thing that entropy is always in the process of destroying: concentrated, ordered, structured existence itself. We have meticulous language for the dissolution. We have no comparable term for what is being dissolved. We measure the falling but have never named the height.

What I discovered, over twenty-five years of thinking about this asymmetry—and one intense year of finally writing it down—is that naming it changes everything. Once you give it a name, once you recognize concentrated, structured contrast as a principle in its own right rather than merely the absence of decay, you can track it. Through biology. Through cognition. Through morality. Through the question of what makes a human life sacred. Through the puzzle of what meaning actually is. And through the strange, specific, 3,500-year story of a people who built their entire civilization around a single, radical commitment: the refusal to become the same as everyone else.

I found that the thread doesn’t just connect these things loosely, as metaphor. It connects them structurally, as instances of the same principle operating at different scales. And when I followed that thread to its end, what I found at the bottom was not what I expected.

I am not going to lay the full argument out here. It took an entire work to build, and it would be dishonest to pretend it fits in a Passover essay. But I will say this much about where it leads.

It resolves problems that professional philosophers have struggled with for decades. It offers a grounding for why a human life carries a moral weight categorically different from any other form of life—not because a sacred text declares it, but because of what human beings uniquely do in the structure of reality. It offers an explanation for why the world’s oldest hatred has the specific shape it does—why it is always disproportionate, always paranoid, always casting the Jew not as inferior but as dangerously powerful. And it offers an account of why a small, stubborn people has outlasted every empire that tried to destroy it, while those empires have crumbled to dust.

The argument does not ask you to believe in God as a starting premise, though it arrives at the question of God on its own terms. It does not ask you to accept anything on faith. It begins with a law of physics that any science-minded teenager can verify, and it follows that law, step by step, into territory I believe has never been charted in quite this way.

I wrote it for the fifth son. I wrote it because I believe he deserves an answer that does not insult his intelligence and does not depend on premises he has already abandoned. I wrote it because I sat across from a 14-year-old boy last Passover and realized that if I couldn’t explain to him—in terms he could test, in language he could trust—why his inheritance was worth carrying, then the failure was mine, not his.

The seder teaches that every child must be addressed in his own language.

Our generation has produced a son who no longer hears the old language at all. He is not hostile. He is not foolish. He is not broken. He is simply waiting for someone to meet him where he is and answer his question without flinching.

That question is not “Is there a God?” It is something prior and more pressing: Is there a reason—a real reason, one that doesn’t require me to accept something I can’t verify—for me to remain a Jew?

I believe there is. And I believe it is among the most compelling reasons anyone has ever been given for holding onto this exasperating, magnificent, indispensable identity.

This Passover, I’d like to try to bring the fifth son back to the table. The argument is waiting for him.
