The last walk before dark

The sun went off the far ridge about four minutes before I got to the top of the knob.

I was late and I knew it. I had a whole plan for the last hour of light and I did most of it wrong.

Bo came up past me with the collar going, because of course he did. He has never once walked behind me on purpose.

The wind is doing something unhelpful to the creek. It is the same wind it has been all week, and it has not made up its mind once.

Here’s the thing I got wrong, and I’ve been carrying it for two years. In a notebook of mine, in the back, there is a list of things I thought I knew. There’s a line about the moon in it. The line says the moon has weather on it.

I didn’t know where I got it, and that’s the part I want to be honest about first. I didn’t read it anywhere I can name. I’ve been saying it. I have said it on this ridge, at my own table, and to a man at a shop.

And nobody ever stopped me on it, which is the part that had started to worry me. If it had been something odd I’d have been asked about it. Nobody asks you about the moon.

Tonight I went out to see whether it was true. I didn’t have a telescope. I had my eyes and a dark sky and about an hour, which is not much of a method, and I’ll come back to that.

Here’s what I want to tell you about that first, because it is the good part. Then I’m going to tell you how badly I got the rest of the night. That part is also true, and it is longer.

I got to the knob and the light was already off the creek. That’s a real thing you can watch happen.

The sun leaves the far ridge and the valley doesn’t go dark at once. It goes from having a sun in it to having a colour in it. The colour is the ridge itself, blue, and then the blue runs down the walls.

Then the moon came up over the eastern end and I could see the edge of it. And I want to be exact here, because the whole thing is standing on this one point.

There was no weather on it.

There was no cloud and no wind and no water moving. There was ground.

It was rough ground, hills on it and hollows between them. The light came in sideways at the edge and threw shadows long enough to measure.

I stood on a ridge in the Ozarks with a notebook full of my own wrong sentence.

And I looked at a moon that is doing the one thing the sentence did not allow for. It is a place. Not a plate. Not furniture.

I had been looking at it wrong for years. Not because I was careless, because the sentence was in the notebook and I never went back and looked. That’s the whole of it, and I’m going to spend twenty five minutes proving it.

So here’s the question for today.

Why do we keep saying a thing we have never checked, when checking it would take one walk and a clear sky?

I’m not asking about the moon. Everybody already knows what I’m asking about, and I want to say the second question too, because the first one is the easy one. The second question is why it is so easy. There’s something about a wrong sentence sitting in a notebook that makes it survive two years.

I don’t have an answer for the second question tonight. I have one for the first one, and I’m going to go and get it.

So I went and got the man who did the looking.

Here is where I’m borrowing from. I’m standing outside that whole old way of thinking, and I’m taking one thing out of it.

That’s the polite way of saying I’m borrowing.

The name is Galileo. Italian, fifteen sixty four to sixteen forty two.

We have already had his evening. I’m not going to stand him up again. I told you about the tube he heard about in the summer of sixteen oh nine. I told you about the four lights going round one of the other worlds in January of sixteen ten. And the phases of the nearer one.

And I told you about the book he printed in March of sixteen ten, so that other people could go out and check him.

All of that’s a different walk and it is a done one. Tonight I only want the moon. One moon, one night, twenty minutes of looking.

Because I want to say what he was arguing with, and I’m going to keep it plain. There had been a very long time when the moon was a smooth thing.

Not because anybody had looked at it and found it smooth.

Because it looked smooth, from a long way off, with the wrong kind of eyes.

And then everybody agreed, and then nobody had a reason to go and check.

That’s all. It doesn’t take a villain. It just takes a thing that’s far away and everybody agreeing about it, twice, and then it stops being a question.

The moon was the easiest of them. There are plenty further out.

Because here’s what I found when I went and read him properly, and it is not what my notebook said. He didn’t say the moon has weather. There’s no weather in it anywhere in what he wrote.

He said the moon is the same kind of thing as this ridge. Rough, with mountains, with valleys between the mountains. And he did the thing that put me on the knob tonight.

He looked at the edge of the light, the place where the bright part runs into the dark part, and he measured the shadows there.

A mountain throws a shadow across the flat ground beside it. Near that edge the shadow is long, and from the length of it you can work out how tall the mountain is.

And he did that for months on end. Night after night, in and out of winter, drawing what he could see by lamplight and writing down what he made of it.

I know that because his book is mostly that in it. The moon is several pages of the thing, and most of the pages are the surface.

And the surface is what I’ve been wrong about in my head for two years.

He didn’t glance at it once. He worked at it. He didn’t do it at the middle of the moon, where it is flat and the light is straight down and nothing casts anything. He did it where the light is going. The edge. The line between lit and not lit.

That’s the whole of what I take from him, and I’m not going to say his line. I’m going to say mine.

The edge of the light is where the shadows show the shape.

Everything in the middle is guessable. A bright round thing with dark patches on it. You can look at that at noon from a porch and make up whatever you like and it will fit. Go to the edge and it stops being a description, because the shape has to fit the length of the shadow.

And that’s why my notebook was wrong, and how I know it is wrong. My sentence had no shadows in it. Weather has no shadow, and you can’t check it from a ridge in Missouri with your own two eyes, and neither could he. The sentence was made of the part of the moon I could have made up.

Now, he got the heights badly wrong. I’ve said before that he thought they stood higher than anything on this earth, and it turns out he was very wrong about that.

Here’s what I take from the being wrong, which is a different thing. The edge of the light is what lets you be wrong out loud in a way that can be corrected.

He said a number that was too big, and he printed it. A man with a better instrument could come along later and put a smaller number there. Compare that with the sentence in my notebook. There was no place to put a smaller number, because the sentence had no shadow under it.

Now the price of holding on to that, which is the part I don’t enjoy.

If the only true things are the things with a shadow under them, then most of what I say on a walk has none. The blue going down the valley. The good dog. The four minutes I lost in the morning.

None of that has a number in it. You can’t work out how tall the blue is.

And I notice that I’ve built most of this on the unmeasurable part. On the weather, on the hour, on being out there. If the standard is a shadow with a length in it, then this ridge is a decorative object. With a dog in front of it.

I don’t think that’s the right way round, and here is the honest reason. He looked at the moon for twenty minutes with an instrument and got a wrong answer that could be improved. That’s what the edge is for, and I want that.

But I’ve also got the other half, and I don’t have a name for the man for it yet.

The name is Humboldt. German, seventeen sixty nine to eighteen fifty nine. He was the man who would not let the world be a list of places.

He went round a lot of it. He took instruments with him and came back with numbers, and then he spent the rest of his life arguing that all of it was one thing.

I’m borrowing one idea from him, and it is not his sentence, it is mine. The ridge I’m standing on is not a hill. It is a piece of a whole arrangement, and the whole is bigger than the light on it, and I’m inside the whole.

I want to be careful here, because this is exactly the place where I could slide into something I should not.

I’m not going to stand on a ridge and tell you that I felt the size of it. That’s a thing people say, and I’ve said it, and I don’t know what it means and I can’t measure it.

Here’s what I can say that’s smaller than that. The moon tonight was at the far end of a long evening, and it was a place, and I found that out by walking out in the dark and looking at one edge of it.

The bird in the creek below me right now is not doing that. It is just doing what it does in the last of the light, because that’s the hour it does it.

All of that happened on the same ridge within an hour of each other. The blue going down the wall, and the moon at the edge, and the bird with no idea that either one is going on.

Humboldt’s whole project was saying those are the same arrangement. I’m borrowing that, and I’m not borrowing a feeling about it.

Now back to the ridge, and to what I got wrong. The wind stopped while I was saying that, which is the trick this wind does.

Bo got up off the rock he has been lying on, went about ten feet, and lay down again on a different rock in the cold. So the light is nearly done.

And I want to say one more thing about twilight, because I’ve been wrong about that too, in a smaller way. There’s a habit of calling this hour nothing. The day is over, the useful part is gone, now it is just waiting.

That’s the same mistake as the smooth white plate. You look at the part where nothing is happening.

There’s an old name for the man who disagreed with that, and he’s not the one I’ve been borrowing from all evening.

The name is Basho. Japanese, sixteen forty four to sixteen ninety four. He wrote very short poems, and his whole objection was to a poem that was working too hard.

The one I’m borrowing is not about effort. It is about the hour. A very short poem, in his tradition, is a thing that gets one subject and looks straight at it. And twilight is a subject. It gets a poem of its own, standing on its own, not as the part where the day is over.

I’m not going to read you one, and I’m not going to describe it either. A description is a quote with the edges taken off, and it is just as easy to recognise.

A great many short verses go around under his name that other hands wrote down.

So the record of what a dead poet actually said is not as solid as the record of people wanting it to be his.

So the idea I take is the shape of the argument, not a poem. An hour that’s going doesn’t have to be an absence, it can be the subject.

That’s what I already said about the light along the ground.

And he had got there first, a long time before I had an instrument of any kind.

Something is happening in this hour. It is the only hour of the day when the light is going along the ground instead of down onto it.

Every rock has got a long thin shadow off it. Every stalk. The edge of the creek is a bright line, and it is bright because it is the last thing the light is hitting.

If you only ever walked at noon, you would never know a cove had a shape.

That’s the whole of it. The dark is not the absence of the day, it is the part of the day with a shadow on it. And you can only see the shadow while the light is still there to throw it.

And then the stars come, and I want to say the thing I actually think about them, because it is not what I expected.

They are the most reassuring thing in this whole thing and I cannot give you a reason with a shadow under it.

Why is that? Here’s what I have got instead, and it is smaller than a reason. When the stars are out, the sky is not showing you anything new. There was all of that up there the whole time. The moon out is not new either, it is the same moon, it just has an edge on it now.

Nothing at this hour is added. It is all the same arrangement, out there, with the light off it.

And that’s the only reason I can stand out here at all. If the dark were a new thing, it would be a bad hour. It is not a new thing. It is the day I already had, unlit.

Now, the part I said I’d tell you, and I’m going to say it flat.

I got the walk wrong. I came out late.

I stood on the knob about ten minutes after the light had gone off it. Late enough that the first thing I saw was the moon, and the last thing I saw was my own boots.

I had no business being up there with no light and no telescope. I’ve walked these ridges for years and I know which parts of them have a drop on the right.

I got lucky, and I want that on the record before I say anything else.

And the thing I was actually trying to do, which I never wrote down, was to catch the exact minute the stars came.

Why not? You cannot do that.

You do not stand there and the sky hands you the minute. The light doesn’t have a line in it. You are out there deciding, and deciding is the part that was never the problem.

I’ve been treating that as a thing that happens to me.

It is a thing I do. Every evening, I decide that the day is over about twenty minutes before it is. I’m not wrong about very much, and I’m wrong about that one every time.

The moon told me where I had been wrong for two years. It didn’t tell me where I’m wrong now, which is a different sentence, and it never will. A moon is not going to check my evenings for me. Nobody is.

And that’s why it is worth walking out and looking at one edge of one thing.

Before you get too sure of the rest of it.

Bo has opinions about the wind and they are all the same opinion.

Here’s where this lands, and I’ve thought about it for two days, which is a long time for me.

That sentence in my notebook didn’t survive because it was a good sentence.

It survived because it was easy to say in the dark.

And because nobody ever asked me where I got it, and because I liked being the sort of man who had looked at the moon.

Three things in one wrong sentence. Cheap to say, nobody checking, and a little bit of a story I liked being in.

That’s not a moon problem. I could put that sentence in about a person, or a town, or a thing somebody told me about somebody else, and it would hold just as long.

The moon was the easy case. The moon has an edge on it, and the edge has shadows on it, and the shadows have lengths in them. Most of the sentences I keep don’t have any of that.

And the reason that matters is not that I get things wrong. It is that a wrong sentence with no shadow under it can go out into a room of people. Every one of them will believe it, and it will never once be checked, because there was never a place where a number could go.

That’s what I take from tonight. The place a thing can be proved wrong is not optional. It is the whole difference between saying it and knowing it.

I have two thirds of that and a bad plan for the timing of my evenings. I don’t know that it is all of it.

Here is the thing to try, and it takes one walk out of a door. Don’t do it tonight. You will be standing about in the dark going at things, and that’s what I did.

Do it on a walk in the last hour of light, and pick one thing out on the ground ahead of you. A fence post. A big rock. A tree at the edge of the path.

Look at the edge of its shadow where the shadow meets the grass. Not the middle of the shadow. The edge.

Say out loud one thing you can tell about the shape of the thing from that edge alone. Not its history. Not who put it there. Its shape.

The somebody who could hear you is allowed to be a dog. That’s the whole assignment. One walk, one thing, one sentence about how it is shaped.

And then, if you want the rest of it, the second half. Find one sentence you’ve been carrying that you’ve never once checked. Not a big one, not a thing about yourself you would have to do something about. One about the weather, or a road, or a thing somebody told you at a shop.

Then go and find out whether it has an edge on it. That’s the whole test. Somebody with a better instrument either could put a different number there, or could not. If they could not, the sentence has no place a number could go.

If it doesn’t have a place where a number could go, that’s your answer. The answer is that you’re carrying a guess.

That’s a ten minute walk. It works on the way to the mailbox, and it needs nothing but your eyes and a bit of low light.

If you skip it, you’ve got twenty five minutes of a man admitting he had the moon wrong for two years, which is its own kind of exercise.

And one more thing for anybody going further, and it is optional, so stop reading here if you want. Do it for a week. One thing a night, seven sentences about the shapes of seven things.

On the seventh night, write the seven down. Not the answers. Just the seven words you used for shape.

You will find about four of them are the same word, and you’ll have no idea when you started saying it. That’s the week version. It is not required, and there’s no way to do it wrong.

That’s everything I have. Go and look at one edge of one thing before dark.

Bo is cold. The light is gone. I’m going with it.
