Sharpened, Not Erased

1.

On his thirtieth birthday, September 11, 1933, Theodor Adorno’s right to teach was revoked.

The German term is venia legendi, the permission to read. Not permission to hold an office or draw a salary. Permission to read aloud, in a room, to people who came to listen. It was taken from him along with the credentials of every other professor the Nazi regime classified as non-Aryan, and what he lost that day was not a job. He lost the ability to say what he thought, in a room of any number of people, and have his thoughts heard, engaged with, argued with.

I want to begin there, in a room like the one he lost.

I am often on Zoom with my chevruta partner for an hour or two, both bent over the same few lines. While studying Yoma last year, I said the sugya was building toward one conclusion. She said it seemed to be building toward another one. We went back through those four lines again and again, each time slower, as if the words might change their mind if we pressed them right. In the SVARA method, we often find this to be the case, that pressing deeper into a word reveals something yet to be seen. So we kept turning the text, and turning it again. Neither of us was trying to win, to make the other’s reading smaller or, worse, to make it disappear. What we both wanted was for the text to give up more of itself than it had given us the moment before.

The tradition has a name for this kind of encounter: milchemet haTorah, the war of Torah. Before asking what kind of war this actually is, it’s worth asking what has to happen inside of us before we’re capable of waging it in the first place.

II.

Bamidbar, the book of Numbers, opens with the people in the wilderness, and midrash asks why Torah could only be given there:

כָּל מִי שֶׁאֵינוֹ עוֹשֶׂה עַצְמוֹ כַּמִּדְבָּר, הֶפְקֵר, אֵינוֹ יָכוֹל לִקְנוֹת אֶת הַחָכְמָה וְהַתּוֹרָה

“Anyone who does not make themselves like the wilderness, ownerless (hefker), cannot acquire the wisdom and the Torah.” — Bamidbar Rabbah 1:7

Hefker is a technical term in halacha, meaning property that belongs to no one, and is for that reason available to anyone. The wilderness has no fences, no titles or deeds, no name carved or flag staked into it. To receive Torah, the midrash insists, a person has to become like that terrain: unclaimed, holding no fixed opinion they need to defend.

I have returned to this teaching over the course of my summer break because I think it names something more foundational than a precondition for a certain mode of study. It’s closer to a description of what our relationship to Torah has to be, structurally, if it’s going to remain alive rather than become a possession. A tradition that could be owned outright—settled, fenced, deeded to whoever got there first—would stop being able to surprise the people inside it. Hefker is what keeps the field open for someone to find something in it that hasn’t been found before. To put it in yeshivish terms, hefker makes chiddush (new insight) possible.

And it is worth noticing, before we go further, that hefker is something a person declares. It is a speech act. You say the words over a field and the field stops being yours, and anyone may walk into it. The midrash says anyone who does not make themselves so cannot acquire Torah. We have to do something to attain the posture of hefker.

Adorno’s dismissal was also a speech act, but not his own. A document, a signature, a statute within racial law, and a room he had been permitted to speak in became a room he could be arrested for entering. One utterance opens a field to everyone; the other closes a person out of one. The difference isn’t in the vocalizing. It’s in who holds title to what’s being released.

III.

Once ownerlessness is in place, our tradition permits something that would otherwise look like simple aggression. For this, we can turn to how Rashi reads a line from Tehillim, “Gird your sword upon your thigh, mighty one, in your glory and majesty” (45:4), as an address to the Torah scholar:

חֲגוֹר חַרְבְּךָ עַל יָרֵךְ — לְהִלָּחֵם מִלְחַמְתָּהּ שֶׁל תּוֹרָה, וְהוּא הוֹדְךָ וְהוּא הֲדָרֶךָ

“Gird a sword on your thigh — to wage the war of Torah, and that is your majesty and that is your glory.” — Rashi on Psalms 45:4

The sword is literal in the verse and figurative in the reading. The discipline of staying inside a difficult argument is itself the majesty the verse describes.

Rashi names the war. The Gemara, reading one phrase further into the same psalm, names its mechanism. The next verse opens v’hadarcha tzlach, “and in your majesty, prosper,” and in Shabbat 63a, Rabbi Yirmiya in the name of Rabbi Elazar declines to read hadarcha, majesty, at all:

אַל תִּקְרֵי וַהֲדָרְךָ אֶלָּא וְחַדֵּדְךָ… שְׁנֵי תַּלְמִידֵי חֲכָמִים הַמְחַדְּדִין זֶה לָזֶה בַּהֲלָכָה — הַקָּדוֹשׁ בָּרוּךְ הוּא מַצְלִיחַ לָהֶם

“Do not read v’hadarcha (your majesty) but v’chadedcha (your sharpening)… Two Torah scholars who sharpen each other in halacha, the Holy One makes them succeed.” — Shabbat 63a

Two consecutive phrases of one verse, and between them the whole argument: here is the war, and here is what the war actually consists of. The majesty Rashi found in the sword turns out, one phrase later, to be a whetstone. 

Machadedin is a friction verb from the root חדד that means to be sharp, pointed, or wheted. Nothing gets sharp resting beside something else; it gets sharp by being drawn against it, at an angle, repeatedly. Both parties leave the encounter changed. Hefker is what makes that friction survivable rather than corrosive, because neither person has a fixed position left to defend, the sharpening can’t turn into a contest over who keeps theirs intact.

Adorno’s book Negative Dialectics is built in the same fashion. I’ve been working my way through the book slowly, glacially really, for almost a year and have yet to finish. It isn’t just a book about philosophical problems; it’s a book sharpening against philosophers, chapter by chapter—against Heidegger, against Hegel, against Kant. These being some of the biggest names in philosophy still today. Adorno sharpens himself on named opponents the way the Gemara does. One of those opponents, Heidegger, joined the Nazi party in 1933, the same year Adorno’s teaching license was revoked. Adorno was not trying to preserve Heidegger’s position in the record. He wanted it gone.

I’ll note that the same daf holds a second teaching in tension with this one. A few lines down, Rabbi Yirmiya in the name of Reish Lakish says that when two scholars are nochin zeh la-zeh, pleasant, easy with each other, in halacha, the Holy One listens to them. Sharpening and gentleness, stacked on the same page, neither toppling the other. Our tradition urges us to refuse to choose.

IV.

This week in the Torah we read Eikev, where Moses, standing at the threshold of the land, issues a warning with surgical precision:

אַל־תֹּאמַר בִּלְבָבְךָ… לֵאמֹר בְּצִדְקָתִי הֱבִיאַנִי ה’ לָרֶשֶׁת אֶת־הָאָרֶץ הַזֹּאת

“Do not say in your heart… ‘because of my righteousness G-d brought me to inherit this land.'” — Deuteronomy 9:4

Moses uses two important words in his warning. The first is the word בִּלְבָבְךָ, bilvavcha, which means the interior space inside a human where no one else can hear. What Moses identifies is the story a person tells themselves quietly, a private narrative of earned arrival. But, there is a second word holding a heavy load, בְּצִדְקָתִי, betzidkati. This word points to a sense of righteous vindication. Together, we can begin to see exactly what Moishe Rabbeinu has come to teach.

He repeats the warning twice more, in the two verses that immediately follow. He finishes with a line that leaves nowhere to stand:

וְיָדַעְתָּ כִּי לֹא בְצִדְקָתְךָ ה’ אֱלֹהֶיךָ נֹתֵן לְךָ אֶת־הָאָרֶץ הַטּוֹבָה הַזֹּאת לְרִשְׁתָּהּ כִּי עַם־קְשֵׁה־עֹרֶף אָתָּה

“Know, then, that it is not because of your righteousness that G-d is giving you this good land to possess, for you are a stiff-necked people.” — Deuteronomy 9:6

Three times in three verses. A prohibition that has to be stated three times is a prohibition against something that keeps pushing back up.

What keeps pushing back up is a kind of deed, an entitlement born of self-righteousness. Not the deed to a plot of land. Rather, an interior deed, the kind a person writes in the secret of their own story: I arrived at this reading through careful attention. I have earned my place at this table. I know what this text says. This is the betzidkati move. The word comes from the root צָדַק, meaning to be righteous and justified. The move Moses warned against at the edge of the river Jordan can just as easily capture us when we open up a masechet.

I should note, importantly, that the Torah explains that while the land is not being earned by the people’s righteousness, it is being granted with the excuse of its current inhabitants’ wickedness. That is a painful but meaningful exploration of the tradition that I want to return to in a future essay, but will not explore here. What I will say is that the land was never fully granted to the people of Israel and it always remained deeded to Hashem themself as the Torah comes to teach: 

וְהָאָ֗רֶץ לֹ֤א תִמָּכֵר֙ לִצְמִתֻ֔ת כִּי־לִ֖י הָאָ֑רֶץ כִּֽי־גֵרִ֧ים וְתוֹשָׁבִ֛ים אַתֶּ֖ם עִמָּדִֽי׃ 

But the land must not be sold beyond reclaim, for the land is Mine; you are but strangers resident with Me. — Leviticus 25:23

The connection to hefker is structural, and the geography is no mistake. The wilderness was the space where ownership couldn’t be staked, where the ground itself refused title and deed. Hefker is what that terrain produces in a person: an interior cleared of the story of one’s own merit. What Moses is warning against is the closure of that clearing. The moment of arrival, when what was promised has been sighted, and the heart quietly begins to claim it.

This is why bilvavcha, the interior state of someone, is the operative word. The warning is aimed not at behavior but at orientation. Hefker is also an interior state. It is not just the condition of ownerless property, but, as the midrash and Torah come to teach us, it is the condition of a person who has set aside the private story of their own deservingness. Its opposite is not pride performed in public. It’s the quieter story that runs in the background, shaping how you hold everything you encounter next.

Bring this inside the beit midrash: the person who comes to a sugya with the conclusion already settled—not because they’ve studied the text but because they need it to say something particular—has not arrived at the page in the wilderness. They’ve written the deed before the study began. The sharpening the two chevruta partners are supposed to do to each other can’t function, because there is no open space left to receive it. Milchemet haTorah requires that both people are still capable of being surprised by what the text does.

I invited us to imagine this kind of moment in the beit midrash at the beginning of this essay. That isn’t a stretch for any svaranik. We have honed ourselves through shiur to notice our biases or when we are mistakenly overworking a text to make it bend to our will. Despite our intentional honing of hefker at SVARA, I still catch myself writing deeds before I’ve even cracked the masechet open.

That is one way the wilderness closes: from the inside, quietly, in a sentence nobody else can hear.

Theodor Adorno was born in Frankfurt in 1903, to a Jewish father and Catholic mother. Under Nazi racial law he was classified as Jewish. After the revocation of 1933 he went to Oxford in 1934 and was admitted to Merton College as an “advanced student”, a graduate student once again after having already earned the credential that had just been stripped from him. He kept returning to Frankfurt, because his loved ones were there, until 1938, when returning stopped being a thing a person could do. He emigrated to New York, then to Los Angeles, where he wrote the aphorisms he would collect as Minima Moralia and subtitle Reflections from Damaged Life. In the eighteenth of them, called “Refuge for the Homeless,” he wrote that it has become part of morality not to be at home in one’s own home.

Adorno wrote in a voice that never stopped sounding like a man apologizing for the accident of his own survival. The loss of friends and loved ones to death camps and displacement subsumed him at times. And out of all of that, Adorno wrote a book arguing that a foundational error in Western thought is the assumption that a concept can own the thing it names.

That book is Negative Dialectics. His target is what he calls identity thinking, the western philosophical habit of subsuming a particular thing under a general concept and treating the fit as complete, as though the concept had captured the thing without remainder. Adorno’s claim is that this habit is not ethically neutral, or philosophically viable. A system that resolves everything into a higher synthesis has to discard whatever refuses to fit, and he published this after surviving a regime that had applied exactly that logic to human beings, sorting people into categories, and deciding anyone who didn’t fit could be erased. Negative Dialectics is his refusal to let philosophy repeat that gesture: rather than resolving a contradiction into false coherence, thought has to stay with what he calls the non-identical, the part of the object that the concept fails to absorb. A tidy resolution, for Adorno, is not a transcendent truth. That would be the same coercive maneuver that made, and continues to make, concentration camps thinkable, performed now at the level of a sentence instead of a society.

VI.

I bring Adorno into a conversation about milchemet haTorah because he diagnosed, from the wreckage of a specific historical catastrophe, a problem the Talmud had already built structures to prevent.

Adorno’s fear is that a system oriented toward synthesis will eventually need to erase what doesn’t fit. The Talmud’s own answer to that fear is not merely tolerance for disagreement, it’s a mechanism for permanently recording the side that loses. The mishnah in Eduyot asks directly why the tradition preserves a minority opinion once the law has been decided against it:

וְלָמָּה מַזְכִּירִין דִּבְרֵי הַיָּחִיד בֵּין הַמְרֻבִּין, הוֹאִיל וְאֵין הֲלָכָה אֶלָּא כְּדִבְרֵי הַמְרֻבִּין? שֶׁאִם יִרְאֶה בֵּית דִּין אֶת דִּבְרֵי הַיָּחִיד וְיִסְמֹךְ עָלָיו

“And why do they record the opinion of a single person among the many, when the halacha follows the many? So that if a court later sees the words of the individual, it may rely on them.” — Mishnah Eduyot 1:5

The rejected position is not discarded once the ruling goes the other way. It’s kept, on the books, precisely so that a future court can reach for it. This is the same instinct behind the more famous claim in Eruvin 13b, where a bat kol declares that both Beit Hillel’s and Beit Shammai’s positions, not just the one that becomes applied law, are “the words of the living G-d.” Halacha follows one house. The record preserves both. The tradition doesn’t treat the losing position as a stage that gets sublated into a higher unity; it treats it as something that has to survive the ruling against it, intact, on the page, waiting.

That is what makes Adorno the right philosopher for my curiosity on these texts. He isn’t offering a foreign vocabulary that happens to fit. He’s naming, from outside the tradition, the exact ethical stake the tradition had already built structure around: that resolving a disagreement is not the same as making the losing side disappear, and that a system which cannot tell the difference has already taken the first step toward something dangerous.

It also names what the tradition is protecting against when it insists on hefker first. A person who arrives at the daf holding the deed has something to lose, and a person with something to lose will eventually need the other position gone. The emptying is not humility theater. It is the precondition for a fight that everyone survives.

VII.

This is why the “war” in milchemet haTorah cannot be allowed to calcify into something it was never meant to be. The Zohar, reading the phrase “the Book of the Wars of the Lord” (Numbers 21:14), draws the sharpest possible distinction:

כָּל קְרָבִין דְּעָלְמָא, קְטָטָה וְחוּרְבָּנָא. וְכָל קְרָבִין דְּאוֹרַיְיתָא, שְׁלָמָא וּרְחִימוּתָא

“All the wars of the world are strife and destruction. And all the wars of the Torah are peace and love.” — Zohar, Beshalach 17

An ordinary war has a loser who stops existing in one way or another. Milchemet haTorah, done as the tradition intends it, refuses that outcome on principle. Both sides remain sharpened, not erased. 

Adorno spent his life tortured by the former, surviving two world wars with incalculable strife and destruction. His negative dialectic describes something closer to milchemet haTorah, where friction is generative and neither side is erased in the final synthesis. My wager, and maybe Adorno’s too, is that we could live in a world that recognizes this distinction and refuses the easier path of one position cancelling out the other.

Though all of this surfaces a question I painfully cannot resolve: does the Zohar’s distinction describe a discipline available mainly to people who are safe? Is preserving the losing opinion and letting the war end in love the architecture of a room where nobody is trying to wage a genocide or burn the olive groves of their neighbor? 

VIII.

I want to end here without pretending things are wrapping up cleanly.

The same tradition that requires a person to become ownerless before Torah can be received also calls the whole of Torah study kinyan, acquisition. Pirkei Avot’s sixth chapter, devoted to praising Torah, lists forty-eight things by which it is acquired: not a single deed or transfer among them, but study, attentive listening, humility, joy, service to the sages, argument with colleagues, a life of relational practice, insistently named this an acquisition.

I don’t think this is careless language. I think the tradition needs a word for what happens when Torah becomes yours, and acquisition is perhaps the only one available, even though everything else it teaches about getting there—becoming hefker, urgent warnings from Moses, holding contradiction, these and these are the words of Hashem, let the war end in love—describes something that cannot end in ownership at all.

Return to me and my chevruta. An hour has passed. Neither of us won. What exists now, instead of a resolution, is a sugya that is sharper than it was, and two readers who are, in some small way, no longer exactly who they were when they sat down. Whatever we have acquired, neither of us owns it. Yet it is ours.

The truth is that the wilderness can close in different ways. One kind of closing happens in an internal utterance nobody else can hear. Against that, I can keep learning in order to catch myself. Some seek to close it through interpretations and applications of our tradition that lead to literal death and destruction. We don’t control every closure and we must still contend with every one. The stakes are too high to stop with what happens in chevruta.
