“From the Grammar of God to the arithmetic of One”.

The Bracket and the Pencil

Before any of this was philosophy, it was a pencil.

You drew the little roof and tucked the big number under it. You put the divisor outside on the left. Then you started the walk: goes into, how many times, write it up on top, multiply, bring it down, subtract, bring down the next digit, and go again. It was the first piece of real machinery a child was handed, and there was a satisfaction in it that nothing else in the school day offered, because you could watch a large mess get taken apart into an answer one column at a time.

And then, most of the time, you arrived at the bottom and there was something left.

Not enough to go in again. Not nothing. A crumb. And there was a whole convention for it, which is the part I had entirely forgotten until this week: you wrote the answer up top, and then out at the end you added a small r and the amount that would not fit. A lowercase letter and a shrug. A footnote to your own work.

That was the remainder, and I want to say plainly what it taught, because it taught it to every one of us and none of us noticed. It taught that some things do not come out even. It taught that the world is mostly divisible and there is usually a little something at the end that will not go in, and the correct thing to do with that something is to note it and move on.

Seventy years later, a sentence about that crumb came off a calendar and hit me full tilt.

The Calendar on the Counter

It was a Zen page-a-day, and it was Nyogen Senzaki, and it said that there is no remainder in the mathematics of infinity.

All life is one, he went on, and therefore there cannot be God and man, nor a universe and God. A

god not in this world is a false god, and a world not in God is unreal. All things return to one, and one operates in all.

I have believed the oneness of all things for a long time. I did not expect to be handed it as arithmetic.

Which is the first strange thing about this whole business, and worth saying before anything else: the sentence that got me was not an equation. It was a word. And it was not even one of the noble words of mathematics. It was the word for the part that will not fit.

The Boy Who Was Not a Math Person

I was not a good math student. I have said that about myself for most of a lifetime, and I have said it in the easy tone people use for something long settled.

It was, I think, a prophecy that arranged its own fulfillment. Somewhere early a boy decides, or is helped to decide, that he is not a math person, and from that moment a case gets quietly assembled. Every wrong answer is evidence. Every right answer is luck. The verdict is written before the test is handed back, and after that the boy is not learning arithmetic, he is confirming a ruling.

I know that voice now, because I have been introduced to it from another direction. It is the same one that stands in the court and brings the charge, and it never cares which way the ruling goes as long as it gets to hold the gavel. In the classroom it wears a pencil behind its ear.

And there was no Ann Tracey in that room. In 1968 my freshman English professor believed in me before I had earned it and kept slipping the word receive onto my spelling tests, and being received is what first lets a person hope. Nobody ever did that for me over a column of figures. There was no one standing beside the long division saying, you are welcome here too.

But physics I loved, and I have wondered why, and I think the answer is simple. Physics is mathematics that has agreed to be incarnate. It is thisness with numbers on it: this apple, this light, this stone falling now, this water finding its level. The reasoning was never the problem. I wanted the world in it. The man who would later write eleven sections on time out of Rovelli, and an essay on the smell of wet earth, was never going to fall in love with an abstraction floating free of a body. I was waiting for the arithmetic to show up wearing one. It took until this month, and it showed up carrying the leftovers.

What the Word Was Holding

So I did what I do, and turned the word over to see the back of it.

Remainder is re plus the Latin manere: to stay, to dwell, to abide. It is the same root under remain, under permanent, and under mansion, which began simply as a place where somebody stayed. Its Greek cousin is menein, and menein is the word in John 15 — abide in me — and it stands behind the many dwelling places in the Father’s house.

Sit with that for a moment, because I had to.

The term that long division uses for the crumb that will not go in is built from the holiest verb in this entire catalog. Remainder means the part that stays behind. The part that abides.

Which means Senzaki’s sentence can be heard two ways at once, and both of them are true. There is nothing left over. And there is nothing left outside — because at that scale the abiding is not a fragment at the end of the line. The abiding is the whole thing.

The Missing A

Now the part I did not plan, and would not have found on purpose.

Writing to a friend about all this, I nearly misspelled the word. I dropped the a that follows the m, and I caught it in time, and then I looked at what I had almost written.

Take the a out of remainder and you have reminder.

One letter. The word for the thing that is left over, and the word for the thing that calls you back to mind, are separated by a single vowel that nobody hears anyway.

And they are cousins in structure if not in descent. Remainder is to stay behind. Reminder is to bring back to mind — the same re, the turning-again that runs through re-member, through recognize, to know again, and through recognition itself, which is why recognition always feels like remembering something rather than learning it.

This catalog has a history with slips. An aspen grove came out of two people getting one word wrong in sequence. The accuser arrived because I read a friend’s name as something else entirely. I have stopped treating these as noise. When the hand goes somewhere the mind did not send it, I look at where it went.

And here is where it went. Every remainder I ever wrote at the end of a problem was a reminder, missing one letter. The crumb that would not go in was not the failure of the arithmetic. It was the small persistent signal that I was dividing something that does not divide.

Keep Dividing

Because the schoolroom was not finished with us, and the next year it showed us the other move. Do not stop at the crumb. Put a decimal point after the answer, add a zero, and keep going.

And the remainder does not vanish when you do that. It stretches. One divided by three will not resolve

on your paper, ever; you write a three, and you bring down a zero, and you write another three, and you would still be writing them at supper. The teacher says that is enough.

But the endless tail is not the arithmetic breaking down. It is the exact answer, told honestly, by a system that has run out of paper and not out of truth.

And then the fact that ought to be famous and somehow is not: point nine repeating is equal to one. Not nearly one. Not one for practical purposes. It is one, exactly, with a difference of precisely zero between them. The endlessly-not-quite turns out to have been the whole thing the entire time.

There it is, in a fourth-grade notebook. In the finite, there is always a crumb. Extend the very same operation without end, and the crumb resolves into perfection. Same divisor, same dividend, same walk down the columns. The only thing that changed is whether you stopped.

A child with a dull pencil is doing Senzaki’s sentence and has no idea. I certainly did not. I was busy being someone who was not good at this.

The Arithmetic of the Whole

The mathematicians, it turns out, have been saying the strange part out loud for a long time, and they say it without any mysticism at all.

An infinite set is defined by the property that would be a scandal anywhere else: it can be matched, one for one, with a part of itself. Every whole number can be paired off against every even number, forever, with nothing left over on either side — and there are, in the only sense the word can carry here, exactly as many. The part equals the whole. That is not a poetic flourish; that has been the working definition since the eighteen-eighties.

Which is the teardrop and the river with a proof set underneath it. No drop is the river, and the river is every drop.

There is a hotel in the literature with infinitely many rooms, and it is full, and a traveler arrives, and there is room. Move everyone down one. There is always room, forever, and no last guest. I wrote in Liberty that liberty is the room we make so that everyone can stand upright at once. I did not know the arithmetic had already built the lobby.

And the plainest one: infinity minus one is infinity. Nothing can be subtracted from it. The Source minus one soul is not less. The girl in Wheat Ridge whose first name three of us have tried and failed to recover is not missing from the total.

Here I want to put a fence around my own enthusiasm, because this is exactly where a person like me starts borrowing authority he did not earn. None of this is proof of anything I believe. A real infinity

is not a very large number, mathematicians were not doing theology, and I am not going to dress an

analogy in a lab coat. This is what I have called corroboration, not derivation: two people walking in from opposite ends of a field and reporting the same warmth. The finding is not therefore oneness is true.

The finding is that the leftover disappears whenever a system is followed past the finite, and that this is

worth a man’s attention on a Tuesday morning.

Three Words and a Zero

Three more words opened on the way through, and one numeral.

Individual is in plus dividuus: not divisible. Our own word for separateness testifies against itself. It means the thing that cannot be split, and we have been using it for four hundred years to mean the one who is standing apart from everybody else.

Divide I wanted to be dis plus videre, to see apart, because that would have handed me the accuser on a plate — division as a viewing angle before it is an operation. The honest reading does not support it; the

-videre in dividere comes from an older root that means to separate, not from the videre that means to see. The ear hears the other thing anyway. I will note what the ear hears and let the etymology stand as it is.

Integer, the name for a whole number, is in plus the root of tangere: untouched, intact. It is the same word as integrity, and the same word as entire. Mathematics calls a whole number by the name we give a whole man.

And zero is The Missing in a numeral. It arrived late, out of India and then through the Arabic sifr, meaning empty, which is also where we get cipher. For most of human history it was not a thing anybody knew they did not know. It was an unnoticed absence — and the instant somebody noticed it and gave it a name, reality reorganized and arithmetic grew up. A missing is realized by the noticing. Every number you have ever written down is standing on a nothing that had to be seen first.

Nyogen, the Non-Dweller

I went looking for the man on the calendar, and the man matched the sentence.

Nyogen is reported to mean non-dweller. He was a Japanese Zen teacher who came to San Francisco in 1905, and he never had a temple in his life. He hired halls. When he could not hire a hall he taught in somebody’s living room, and he called the whole thirty-year arrangement his floating zendo. He described himself as a mushroom, with no deep root and no branches and no flowers and probably no seeds, and he was wrong about the seeds, because much of Zen on this coast came up out of those rented rooms.

A man named No-Dwelling, teaching that there is no staying-behind, in a hall he did not own. That is the epigraph of this entire collection standing up in a borrowed room: keep showing up to the game even when the stadium is not yours. He belongs beside Roth’s Ruppert Mundys, homeless and still taking the field.

And then the part I will not skip.

From 1942 to 1945 Nyogen Senzaki was behind American wire at Heart Mountain, Wyoming, classified an enemy alien at sixty-five years old for being a Buddhist priest. In those same years my father was a forward observer working from North Africa and Sicily toward the Ardennes. Both of those facts belong to the same country, and both of them belong in this essay, and I am not going to reconcile them for you. I said in Receiving the Country that receiving does not cancel the work, and a more perfect union is never finished. This is what the unfinished part looks like with a date on it.

What he did inside the fence is the hardest half of his own sentence. Rounding people up is precisely the arithmetic of the remainder — somebody deciding which portion of the population is the part that does not go in evenly, and setting it aside with a small letter beside it. He was told he was the leftover. He renamed the camp the Mountain of Compassion, and he named the meditation hall he built there the Meditation Hall of Eastbound Teaching, on the reasoning that the teaching had been travelling east since India and was simply continuing. He refused the category from inside it, and he refused it without a trace of contempt for the country that had put him there.

That is a yes with a no folded into it, wearing a number on a tag.

Beating the Register

There is evidence in this case that I have been sitting on for sixty years, and I did not recognize it as evidence because I have always told it as a joke.

My first job was cashiering in a supermarket. This was before scanners, when the register was a machine with keys that you hit hard, and the customer handed you a ten for a purchase of six dollars and forty-one cents, and the machine told you what to give back.

I beat it. Every time. I had the change worked out in my head before the drawer came open, and the register was not telling me the answer. The register was confirming mine.

I have told that story for decades as a small boast, the way a man tells you he could once throw a football through a tire, and I have told it in the same lifetime in which I have said, flatly and often, that I was not a math student.

Both sentences have been in my mouth for fifty years and I never once put them in the same room.

Look at what that job actually required. Subtraction under load, in public, in front of a stranger, with a line behind him and a manager somewhere in the store. Fast, accurate, continuous, all day. Nobody who cannot do arithmetic lasts a week in that lane.

So the ruling was wrong. Not generous of me — wrong, as a matter of fact.

And I can see now what the difference was between the lane and the classroom, because it was never the arithmetic. In the store there was no red ink. There was no grade, no case being assembled, no file in which every wrong answer became evidence and every right one became luck. The register simply said yes, quietly, several hundred times a day, and asked nothing else of me.

I was not bad at math. I was bad at being graded. Those are entirely different conditions and only one of them is about numbers.

I have written this month about a verdict that arrives before a man does, and about the fact that a case dismissed without prejudice may be brought again. Here is one being brought again. The boy at the arithmetic desk was tried by the same official who tries the man in the parking lot, the ruling was entered before the evidence, and the evidence was standing at a checkout counter in an apron the whole time.

Dismissed. Without prejudice. And this time there is a witness, and the witness is a machine that agreed with me all day long.

Nobody Is the Leftover

So here is what the crumb was for.

An audit produces remainders. That is what an audit is: the honest, rigorous, necessary process of getting the books to balance, which by its nature ends up with a line at the bottom for whatever would not go in. The auditor is not a villain. The auditor is standing at the gate.

The field on the other side does not have any.

Nobody is the leftover. Not the red-haired girl whose name three siblings cannot recover, and who is nonetheless still being carried sixty-five years later by people who never met her. Not my friend Stan, who is gone and whose friendship never lived inside either of us anyway, so there is nothing to have been subtracted. Not the old priest behind the wire in Wyoming. Not the one who cannot make his own books balance, which at one time or another is all of us.

Universe is unus and versus: turned into one. The word for everything is already built on the verb, though it arrives by a different Latin road than our turn does, and I will say so rather than pretend they are family. All things return to one, said the man on the calendar, and one operates in all — operate, from opus, work. The one is not sitting still. It is working in every part of this.

I was not a math student. I was a boy who wrote a small r at the end of the line and thought it meant he had come up short.

The crumb that would not go in was never a failure of the arithmetic. It was a reminder, missing one letter.
