VII. The Cry Across the Forest

The traveller had been following the birds for several days.

He had begun to recognise their movements.

When they flew low, the forest seemed open.

When they rose into the canopy, something had changed.

When they became still, he became still.

But he did not yet understand their cries.

One morning he was walking beneath the trees when the flock suddenly scattered.

A sharp sound passed through the forest.

The traveller stopped.

He looked around.

Nothing had moved.

The branches were still.

The leaves were still.

The path was empty.

Then another bird cried.

The flock disappeared deeper into the trees.

The traveller looked upwards.

At first he saw nothing.

Then, high above the forest, he caught sight of a dark shape moving between the clouds.

A great bird of prey.

It passed silently overhead.

The traveller watched it vanish.

“So that was what the cry was for,” he said.

But he immediately corrected himself.

For.

That sounded too much like intention.

He waited.

The birds did not return.

By afternoon, the forest had become quiet again.

The traveller walked on.

The following morning he heard the same cry.

This time he was ready.

He looked towards the sky.

Again, he saw nothing.

Yet the birds fled.

He remained where he was.

A little later, the predator appeared.

The traveller stared upwards.

He had not seen it when the bird cried.

But the bird had somehow made the danger relevant before he could see it himself.

He began to wonder what had happened.

The forest had not changed.

The predator had been elsewhere.

The sound had been here.

Yet the possibility of the predator had crossed the distance between them.

The traveller followed the flock.

He found them gathered in a dense part of the forest.

One bird called.

Another moved.

Then another.

Soon the whole flock was shifting through the branches.

No bird touched another.

No branch moved because of them.

And yet each seemed to alter what the others could do.

The traveller sat beneath a tree and watched.

He thought of the garden.

There, a plant had turned towards light.

A root had grown around a stone.

The world had changed what the plant could do.

Then he thought of the bird.

The branch had made landing possible.

The forest had made flight possible.

But this was different.

One bird had made something absent relevant to another.

The traveller looked towards the empty sky.

Nothing was there.

And yet the birds were acting as though something were.

He wondered whether the cry itself was dangerous.

He listened.

It was only a sound.

The wind made sounds.

Branches made sounds.

Water made sounds.

None of these sounds caused the flock to flee.

This one did.

The traveller began to understand that the important thing was not simply that the cry was connected to the predator.

Many things were connected to many things.

The important thing was that the cry participated in the lives of the birds in a particular way.

It could alter what they did.

It could bring something distant into the possibilities of those who heard it.

The traveller picked up a fallen twig.

It had a footprint pressed into the mud beside it.

He looked at the print.

Something had passed through the forest.

The print told him so, in a manner of speaking.

But the animal had not made the print in order to tell him.

The twig beside it had no relation to the animal at all.

The traveller began to see a difference.

The footprint could indicate that something had passed.

The cry could do something more.

It belonged to a world in which one bird could alter another bird's possibilities.

He looked towards the flock.

One bird flew.

Another followed.

Then another.

The first bird had not carried the predator with it.

It had carried only a difference.

And somehow that difference was enough.

The traveller sat quietly.

Perhaps, he thought, this was how the world began to become larger.

Not because more things appeared in it.

But because things that were elsewhere could begin to matter here.

The predator could be absent and yet enter the flock's world.

A distant event could alter a present action.

A sound could mediate between one creature and another.

The traveller felt the old temptation returning.

“Then the bird means predator.”

He stopped.

He had learned enough by now to distrust that sentence.

Perhaps the cry meant nothing in the way a word meant something.

Perhaps no bird thought a thought that could be translated into human words.

Perhaps the cry simply belonged to an organised pattern of relations in which certain differences could alter what other birds did.

That was enough.

More than enough.

For something new had happened.

The bird had not merely responded to the world.

It had altered another bird's relation to the world.

The traveller stood.

He looked across the forest.

The landscape was unchanged.

The same trees stood in the same places.

The same paths wound between them.

The same sky stretched above.

But now the possibilities available to the birds could be changed by something another bird did.

The traveller smiled.

Until now, he had thought of affordances as things the world offered to creatures.

Now he wondered whether creatures might afford things to one another.

A bird could make flight possible.

A cry could make hiding possible.

A warning could make an absent danger present.

And perhaps this was the beginning of a different kind of country.

A country in which possibilities did not merely arise between a creature and its surroundings.

They could travel between creatures.

The traveller followed the flock into the trees.

Behind him, the forest remained unchanged.

Ahead of him, something invisible had already arrived.

VI. The Bird's World

The traveller had remained in the garden for many days when he began to notice the birds.

They seemed to move through the forest by paths he could not see.

A bird would rise from the ground, fly between two trees, turn sharply, and land upon a branch scarcely wider than the traveller's hand.

He watched one bird in particular.

It flew towards a tree.

The traveller saw bark, leaves, branches and open air.

The bird saw something else.

It altered its wings.

Its body tilted.

Its feet extended.

And without hesitation it landed.

The traveller looked at the branch.

“Why that one?”

The bird flew away.

He followed it as best he could.

The bird moved through the forest with astonishing ease.

A gap appeared between two trees.

The bird crossed it.

A narrow branch extended over a stream.

The bird landed upon it.

Another branch was hidden among leaves.

The bird found that one too.

The traveller stopped.

There were branches everywhere.

Yet the bird did not seem to see a forest full of branches.

It moved through a forest full of places to land.

The traveller tried to imagine what this would be like.

He looked at the branch again.

Its surface was rough.

Its colour was brown.

It divided into smaller branches.

Leaves grew around it.

He could describe all these things.

But none of the descriptions explained why the bird had flown towards it.

The bird returned.

This time it landed on a different branch.

Then another.

Then another.

The traveller noticed something.

The bird rarely landed on branches that were too thin.

It avoided those that moved too much.

It preferred certain heights.

Certain angles.

Certain spaces between neighbouring branches.

It was not merely flying through the forest.

It was finding its way through what the forest made possible.

The traveller remembered the garden.

The plants had responded to light without needing to represent it.

But the bird seemed different.

It was not merely being changed by the forest.

It was moving through it.

Finding.

Selecting.

Turning.

Landing.

The traveller watched until he could no longer tell whether the bird first saw a branch and then discovered what it could do with it.

Perhaps, he thought, for the bird the two things were never separate.

Perhaps the branch appeared as a possibility.

He stopped.

The word troubled him.

As.

It was a dangerous little word.

He could say that the bird saw the branch as a place to land.

But what did that mean?

Did the bird possess an image of a branch?

Did it possess another image of a place to land?

Did it compare the two?

The traveller imagined a tiny room inside the bird in which pictures were being examined.

He laughed aloud.

The bird flew away.

“No,” he said. “That cannot be the only possibility.”

He watched it disappear among the trees.

Perhaps seeing was not first making a picture and then deciding what the picture meant.

Perhaps seeing was already shaped by the life of the one who saw.

The bird had wings.

Its body had a particular weight.

Its feet could grasp branches.

Its eyes were sensitive to features the traveller might overlook.

Its whole life had been shaped by moving through this kind of world.

What the traveller saw as a collection of objects, the bird encountered as a landscape of possible movement.

The forest had not changed.

The bird had not invented it.

But the bird's way of being organised made certain possibilities visible.

The traveller looked at the same branch.

He could sit beneath it.

He could climb it.

He could break it.

He could use it for a fire.

The bird could land upon it.

Neither of them was wrong.

They were simply capable of different encounters.

Later that afternoon, the traveller heard a sudden cry.

The birds vanished.

He looked around.

At first he saw nothing.

Then a shadow passed between the trees.

The traveller looked towards the sky.

Nothing.

He looked again.

Still nothing.

Yet the birds remained hidden.

Something had changed.

The forest now felt different.

The traveller remembered the old woman's words.

What can happen between this thing and something else?

He waited.

Then he heard the cry again.

This time he noticed where it came from.

A bird was perched high above him, watching the sky.

The traveller looked in the same direction.

Far away, almost invisible against the brightness, a larger bird was circling.

The traveller had not seen it.

But the first bird had.

The traveller stood very still.

The predator was not merely present.

Its presence had altered the possibilities of the forest.

Branches that had moments before been places for landing had become places for hiding.

Open sky had become dangerous.

The flock moved deeper into the trees.

The traveller followed.

But now something puzzled him.

The predator had been too distant to see clearly.

Yet its approach had already become part of the birds' world.

How?

He looked at the bird that had cried.

It had not pointed.

It had not spoken.

It had not shown the others a picture.

It had simply cried.

The others had responded.

The traveller listened.

The cry came again.

And suddenly the forest seemed to contain a new kind of possibility.

A sound could change what another creature did.

Not because the sound itself was dangerous.

The sound was only a sound.

But something else was happening.

The sound made something absent relevant.

The predator was not here among the trees.

Yet the cry had somehow brought its possibility into the flock's world.

The traveller stood beneath the branches.

For the first time, he sensed that the country was changing.

A difference could matter.

A creature could be sensitive to it.

A creature could perceive possibilities through it.

But now one thing seemed capable of making another thing available without being that thing itself.

The bird called again.

The flock disappeared into the forest.

The traveller followed.

He had the strange feeling that he was approaching something he had been warned not to name too soon.

Not meaning.

Not yet.

But something close.

Something that could point beyond itself.

Something that could make the absent present.

And somewhere ahead, he thought, there must be a difference between being responsive to a sign and understanding what a sign means.

The forest remained silent.

But for the first time, something within it had begun to stand for something else.

V. The Garden That Did Not Speak

At the far edge of the forest, the traveller found a garden.

It was not enclosed by walls.

No one had planted its borders.

Plants grew wherever the ground permitted them, climbing fallen trees, spreading across stones and turning their leaves towards the open sky.

The traveller stayed there for several days.

On the first morning, he noticed a vine growing beside a tall post.

At dawn, it lay close to the ground.

By afternoon, its newest tendrils had curled around the post.

The following day they had climbed higher.

The traveller watched carefully.

“You have found something to climb,” he said.

The vine continued growing.

He touched the post.

It was rough wood.

He touched the vine.

It was soft and green.

Neither seemed to contain the idea of the other.

Yet together they had produced a strange result.

The vine had changed its direction.

The traveller remembered the old woman.

What can happen between this thing and something else?

He watched the vine for a long time.

Then he saw something stranger.

A young shoot was growing towards the light.

As the sun moved across the sky, the shoot slowly altered its direction.

Morning found it leaning east.

By evening, it had turned towards the brighter opening between the trees.

The traveller followed its movement.

“You know where the light is,” he said.

The shoot continued turning.

The traveller frowned.

Perhaps know was too strong.

He tried again.

“You can find the light.”

The shoot continued turning.

He sat beside it.

There was no face to read.

No eye looking towards the sky.

No voice.

No gesture that said there.

Only the slow alteration of the plant's growth.

The next day a stone was lying in the path of a root.

The root approached it.

Then, over many days, divided around it.

One part passed to the left.

The other to the right.

Eventually they met again beyond the stone.

The traveller crouched beside them.

“You have found an obstacle.”

The root did not reply.

He laughed.

“What am I doing?”

He stood and walked on.

At midday he came upon a patch of plants whose leaves had closed.

He returned in the evening.

They had opened again.

The next morning they were closed.

He watched for several days.

Something in the changing conditions altered the plants.

But what?

He thought of the words people used in the villages he had passed through.

Sensing.

Detecting.

Responding.

Knowing.

Reading.

He tried each word against what he had seen.

The words seemed too large.

He returned to the vine.

The vine had not read the post.

It had not recognised the post as a support.

It had not decided that climbing would be useful.

Yet its growth had changed when the post entered its world.

The plant had been organised in such a way that something in its surroundings could alter what happened next.

The traveller looked towards the light.

The light was still light.

It had not become a message.

The stone was still stone.

It had not announced itself as an obstacle.

The post was still wood.

It had not offered itself as a ladder.

And yet each had entered into the life of the plant.

The traveller began to wonder whether this was what the old woman had meant when she said that the country was not one country.

Perhaps there were forms of life for which the world was full of differences that never became thoughts.

Differences that simply altered what happened next.

He found a small plant growing beside a rock.

Its stem had turned away from the rock and towards the open ground.

The traveller moved the rock.

The next day the stem had altered its direction again.

He replaced the rock.

After several days, the plant had turned once more.

The traveller stood over it.

“Do you understand what I am doing?”

The plant did not answer.

He smiled.

“No. That was the wrong question.”

He left the rock where it was.

That evening, as the sun disappeared, he sat among the plants.

The garden was full of responses.

Leaves opened and closed.

Roots divided and changed direction.

Stems bent towards light.

Vines found supports.

Flowers opened at particular times.

Nothing spoke.

Nothing needed to.

The traveller began to understand that there was another kind of relation between a being and its world.

A difference could matter without becoming a message.

The world could alter what a living thing did without first being represented inside it.

There did not have to be a picture of the stone somewhere within the root.

There did not have to be an image of the light inside the leaf.

There did not have to be a little voice saying this way.

The plant changed because the plant was the kind of thing that changed in such circumstances.

That was all.

Yet it was not little.

The traveller looked around the garden.

He had entered it expecting to find silence.

Instead he had found something stranger.

A world in which everything seemed to be responding to something, while almost nothing seemed to be saying anything.

He remained there until nightfall.

The stars appeared.

The plants continued their quiet work.

The traveller lay back upon the ground.

For the first time, he wondered whether meaning might not be the beginning of responsiveness after all.

Perhaps responsiveness came first.

Perhaps a being could be changed by the world long before the world became something it could recognise.

And if that were true, then there was a place between the silent country and the world of meanings.

A place where differences mattered.

A place where possibilities changed.

A place where nothing yet had to stand for anything else.

The traveller closed his eyes.

The garden remained awake.

But it did not speak.

IV. The Many Countries

Beyond the mountain pass, the traveller entered a forest.

At first he was pleased.

Here, he thought, was a country he understood.

The trees gave shade.

Their fallen branches provided firewood.

Their trunks marked the distance between one place and another.

Their roots could be stepped over, though sometimes with difficulty.

The traveller walked for several hours before remembering the old woman's question.

What can happen between this thing and something else?

He stopped beneath a great tree.

A branch stretched above him.

“A good branch,” he thought.

But then he was not sure what he meant.

A bird descended and landed upon it.

The branch bent.

The bird remained.

Soon another arrived.

Then another.

The traveller watched them move along the branch, leaping from one place to another.

“A resting place,” he said.

The birds continued their business.

A squirrel appeared from the trunk.

It ran along the same branch and disappeared among the leaves.

“A road,” said the traveller.

From somewhere beneath the bark came the faint sound of movement.

He placed his ear against the trunk.

Something small was feeding within the wood.

“A house,” he said.

Then he looked down.

At the foot of the tree, a pale fungus spread across the roots.

“To you,” he said, “it is something else again.”

The traveller sat beneath the tree and waited.

As the day passed, the tree became many things.

A shelter from rain.

A ladder for the squirrel.

A hunting place for the birds.

A dwelling for insects.

Food for the fungus.

A source of warmth for the moss growing on one side of its trunk.

By evening, a fox had curled among its exposed roots.

The traveller could no longer decide what the tree was.

At last he climbed onto a low branch.

He sat there for some time.

The branch was firm.

For him, it had become a seat.

Then he remembered the great stone.

He climbed down.

The next morning he followed a narrow track through the forest.

Soon the path disappeared.

He stood uncertainly among the trees.

Above him, a bird passed from branch to branch without touching the ground.

A squirrel followed another route through the canopy.

An insect travelled beneath a sheet of bark.

A root pushed slowly through the earth.

The traveller suddenly understood.

There was no forest.

Not one forest, at least.

There were many.

The ground was his country.

The branches were another.

The spaces between the branches belonged to the birds.

The bark contained passages he could not enter.

The soil concealed routes he could not see.

The air itself had paths.

He stood in the middle of all these countries without having known they were there.

That afternoon he found the old woman beside a small pool.

“I thought I had entered a forest,” he told her.

“And?”

“Now I think the birds live in a different one.”

The old woman smiled.

“Do they?”

“The same trees are here. But what they can do is different.”

She nodded.

“The squirrel also.”

“And the insects.”

“And the roots.”

The traveller looked towards a young plant growing beside the water.

“And this?”

The old woman knelt beside it.

“It cannot walk.”

“No.”

“It cannot climb.”

“No.”

“It cannot fly.”

“No.”

The traveller waited.

“But it grows.”

“Yes.”

She pointed upwards.

“Light comes from there.”

The traveller watched the leaves.

“They turn towards it.”

“Sometimes.”

“Then the light is a path for the plant.”

The old woman looked at him.

“Perhaps.”

“A possibility?”

“Perhaps.”

The traveller frowned.

“But the plant does not know where the path is.”

“Must it?”

He thought of the bird moving through the branches.

Of the squirrel.

Of the insect.

Then of the root moving beneath his feet.

“No,” he said slowly.

The old woman touched the soil.

“This one finds water.”

The traveller looked at the small plant.

“Does the water mean anything to it?”

The old woman stood.

“That is another question.”

And she walked away.

The traveller remained beside the pool.

For the first time, he tried to imagine the country without imagining himself at its centre.

The light fell differently upon the leaves.

The ground held water.

The roots entered the soil.

The branches bent beneath the birds.

None of these things seemed to require an audience.

Yet each entered into the lives of creatures organised differently from himself.

The traveller looked again at the forest.

Nothing had multiplied.

The trees were still trees.

The ground was still ground.

The light was still light.

But the possibilities had become innumerable.

Or rather, he thought, perhaps they had always been innumerable.

He had simply mistaken his own country for the whole of it.

As evening came, the traveller climbed a hill overlooking the forest.

From above, he could see the dark canopy stretching to the horizon.

He thought of the birds moving through its upper paths.

The animals moving below.

The insects beneath the bark.

The roots entering the earth.

The plants turning slowly towards light.

All inhabiting the same country.

All inhabiting different fields of possibility.

The traveller sat quietly.

For once, he did not ask what the forest meant.

He wondered instead:

What could happen here—

and for whom?

III. The Mountain Does Not Yield

Beyond the gate, the traveller came at last to a range of mountains.

For many days he had followed the path between them, and the path had become narrower until it ended at a steep wall of rock.

The traveller stood before it.

“There must be a way through,” he said.

He walked along the foot of the mountain.

The wall continued.

He climbed a little way, but the stone was smooth and offered no hold.

He tried another place.

Then another.

By midday, his hands were bleeding.

“This mountain affords no passage,” he said.

At once he remembered the stone seat.

Perhaps, he thought, that was only true for him.

He sat down and waited.

Before long, a goat appeared high above him.

It descended a slope the traveller would not have dared to approach.

Its hooves found narrow ledges invisible from below.

Within moments it had crossed the face of the mountain and vanished among the rocks.

The traveller watched in amazement.

“So,” he said, “the mountain affords passage after all.”

He began climbing again.

The mountain did not agree.

He slipped.

He fell.

He tried another route.

The stone turned him back.

At last, exhausted, he sat beneath an overhang.

A bird flew across the valley.

The traveller looked at the mountain, then at the bird.

“For you,” he said, “there is no mountain at all.”

The bird did not answer.

Later that day, he found the old woman gathering water from a narrow stream.

“The mountain refuses me,” he said.

She looked towards the cliffs.

“Does it?”

“I have tried to climb it.”

“And?”

“I cannot.”

She filled her vessel.

“A goat can.”

“Yes.”

“A bird can cross it.”

“Yes.”

“And the stream has found a way through.”

The traveller looked down.

Far below the mountain, the water had cut a narrow channel through the stone.

“So the mountain permits some things and refuses others.”

The old woman shook her head.

“The mountain does not permit.”

“But surely—”

She placed her hand against the rock.

“It stands.”

The traveller was silent.

“It has height,” she continued. “Weight. Hardness. Shape. Some parts crumble. Others do not. Water finds weaknesses. Roots enter cracks. Goats find ledges.”

“And I?”

“You have hands.”

The traveller looked at them.

“And feet.”

He looked at the steep rock above him.

“And no wings.”

The old woman lifted her vessel.

“Between what the mountain is and what you are, some things can happen.”

“And others cannot.”

“Yes.”

The traveller thought about this.

“Then the possibilities come from both.”

The old woman smiled.

“That would be too easy.”

He frowned.

She pointed to the mountain.

“Suppose you decide that you can walk through it.”

“I cannot.”

“Why not?”

“Because it is solid.”

“And if you decide very strongly?”

The traveller laughed despite himself.

“Still no.”

“Then your deciding is not enough.”

She pointed towards the stream.

“Suppose the water decides to flow uphill.”

“It cannot.”

“And the goat?”

“It cannot fly.”

The old woman nodded.

“Then perhaps the country is not waiting for its inhabitants to imagine what is possible.”

The traveller looked again at the mountain.

For a moment he felt relieved.

The stone had not misunderstood him.

It had not ignored his wishes.

It had simply been stone.

Yet this did not make the mountain meaningless.

The traveller thought of the goat.

Of the bird.

Of the stream.

Of himself.

The same mountain stood before them all.

But it was not the same country for each.

For the goat, there were paths where he saw only walls.

For the bird, there was open air.

For the water, there were cracks.

For him, there was resistance.

The mountain had not changed.

Neither had they.

And yet what could happen was different.

That evening, the traveller walked along the valley until he found a narrow pass.

There, the mountain could be crossed.

He stopped at its entrance.

The path did not invite him.

The mountain had not decided to become helpful.

The pass was simply there: wide enough for his body, firm enough for his feet.

He entered.

As he walked between the high walls of stone, he began to understand something he had not understood before.

The country did not contain possibilities like objects stored in rooms.

Nor did its inhabitants carry possibilities inside themselves like secret tools.

Possibility appeared in the meeting.

But the meeting was not a negotiation.

The mountain brought its shape.

The traveller brought his body.

The world did not yield to him.

He did not invent the world.

Between them, a path either became possible—

or it did not.

And high above, where the goat moved easily among the ledges, the mountain remained entirely indifferent to the lesson it had given him.

II. The Stone Seat

The next morning, the traveller came upon a great stone beside the path.

It was flat on top and broad enough for a person to rest upon.

He sat down.

After some time, a child came along.

Without hesitation, she climbed onto the stone, jumped from it, climbed back again, and jumped once more.

“What are you doing?” asked the traveller.

“Playing,” she said.

“But it is a seat.”

The child looked surprised.

“No,” she said. “It is a rock.”

She jumped down and ran away.

The traveller remained seated.

A little later, an old man came carrying a bundle of wood.

He stopped beside the stone, placed the bundle upon it, and began to rearrange the branches.

“Useful table,” he said.

The traveller looked up.

“It is a seat.”

The old man laughed.

“Not from this side of it.”

When he had finished, he lifted the bundle and continued along the path.

The traveller was beginning to feel that the country had become unreasonable.

By midday, a fox appeared from the grass.

It climbed onto the stone, curled itself against the warmth gathered there, and fell asleep.

The traveller watched in silence.

Later still, a small bird landed upon the stone.

It pecked at an insect crawling across the surface.

For the bird, the stone had become a hunting ground.

By evening, rain began to fall.

The traveller crouched beside the stone, where its great bulk broke the wind.

The stone, he thought, was now a shelter.

The following morning, he found a young man standing beside it with a hammer and chisel.

“What are you doing?” asked the traveller.

“Breaking it.”

“But it is a seat.”

The young man looked at him strangely.

“Is it?”

The traveller stood.

“It is broad and flat. It supports a person.”

“Yes.”

“Then it is a seat.”

The young man tapped the stone with his hammer.

“It is also stone.”

“That tells me what it is made of.”

“And seat tells me what you do when you meet it.”

The traveller was silent.

The young man placed the chisel against the rock.

“I need smaller stones for the wall.”

He struck the chisel.

A sharp sound rang through the valley.

The traveller felt something almost like outrage.

“You are destroying the seat.”

The young man smiled.

“I thought you said it was a stone.”

And with another blow, he split away a piece.

The traveller walked on.

For several days he thought about the stone.

He remembered the child climbing it.

The old man using it as a table.

The fox sleeping in its warmth.

The bird hunting insects.

The young man breaking it apart.

He himself had sat upon it.

None of them had asked what the stone meant.

They had simply encountered it.

Yet none had encountered quite the same thing.

At last, the traveller returned to the place where he had first entered the country.

The wooden gate still stood between its posts.

He looked at it for a long time.

A fox passed beneath it.

A bird flew over it.

The traveller opened it and stepped through.

Then he stopped.

What was it?

A gate?

A barrier?

A frame?

A source of firewood?

A piece of timber standing upright in the ground?

He remembered the old woman.

What can happen between this thing and something else?

For the first time, the question seemed less like an answer than a door.

The gate had not changed.

It was still wood.

It still had hinges.

It still stood between two posts.

But what could happen there depended partly upon what approached it.

The fox did not need to open it.

The bird did not need to pass through it.

The traveller could open it, close it, lean against it, climb over it, or tear it down.

But he could not walk through it while it remained shut.

Something belonged to the gate.

Something belonged to him.

And somewhere between the two, possibilities appeared.

The traveller placed his hand upon the wood.

It did not tell him what it was.

It did not contain a list of uses.

It did not wait for him to discover its true purpose.

It stood there with its weight, its shape and its grain.

And he stood before it with hands, legs, memories and habits.

Between them was the possibility of opening.

Or not opening.

For a long time, the traveller remained there.

Then he smiled.

The country, he realised, was not made of things with instructions hidden inside them.

Nor was it made of shapeless stuff waiting for creatures to invent its possibilities.

It was something more troublesome.

Things met things.

And in the meeting, some ways became possible.

Others did not.

He opened the gate.

The gate said nothing.

But this time, neither did he expect it to.

I. The Silent Country

There was once a traveller who came to the edge of a country no map had named.

Before him stood a wooden gate.

Beyond it ran a path between low hills.

The traveller looked at the gate and smiled.

“Come in,” it seemed to say.

So he opened it and passed through.

The path continued before him.

“Follow me,” it seemed to say.

So he followed.

For many days the traveller moved through the country, and everywhere he found instructions.

A fallen tree seemed to tell him where to cross a stream.

A broad stone seemed to invite him to rest.

A narrow gap between two rocks seemed to offer a way through the hills.

When rain came, an overhanging ledge seemed to offer shelter.

The traveller began to think the country unusually hospitable.

Then, one morning, he came upon a great cliff.

He stopped at its edge.

Below him was nothing but distance.

“Do not come this way,” the cliff seemed to say.

The traveller stepped back.

By evening he had become convinced that the country was full of voices.

It told him where to go.

It showed him where to rest.

It warned him where not to step.

He began to wonder who had made it.

On the following day he met a fox.

The fox was standing beside a fallen tree.

“A fine bridge,” said the traveller.

The fox looked at him.

“A bridge?”

“Yes,” said the traveller. “It leads across the stream.”

The fox glanced at the water and then disappeared into the undergrowth.

The traveller watched it go.

“How strange,” he thought. “It does not understand the country's instructions.”

Later he came upon a bird resting on the branch of a tree.

“There,” said the traveller, “the branch has invited you to perch.”

The bird flew away.

The traveller stood beneath the tree.

The branch remained.

It did not repeat the invitation.

That evening he met an old woman gathering roots.

“The country is very generous here,” said the traveller. “It is always telling me what I may do.”

The woman looked around.

At the trees.

The stones.

The stream.

The distant cliff.

“Is it?” she said.

“Of course,” said the traveller. “That gate invited me to enter. The path invited me to follow. The cliff warned me away.”

The old woman said nothing.

The traveller waited.

At last she pointed to the path.

“Can you follow it?”

“Yes.”

She pointed to the stream.

“Can you cross it?”

“In places.”

She pointed to a narrow hole beneath a rock.

“Can you enter there?”

“No.”

The old woman nodded.

“Then perhaps the country has not been speaking.”

The traveller frowned.

“But these things make things possible.”

“Yes.”

“And some things impossible.”

“Yes.”

“Then what is the difference?”

The old woman picked up a stone and placed it in his hand.

“This,” she said, “will not carry you across the river.”

She pointed to the fallen tree.

“That may.”

She looked towards the bird now circling above them.

“For the bird, the branch carries something else.”

“And for the fox?”

“The stream has no bridge.”

The traveller looked again at the country.

Nothing had changed.

The gate stood where it had stood.

The path ran between the hills.

The branch reached over the water.

The cliff fell away into the distance.

Yet the voices had gone.

The gate was no longer saying enter.

The path was no longer saying follow.

The cliff was no longer saying beware.

There was only wood.

Earth.

Stone.

Water.

And the different things that different beings could do among them.

The traveller felt suddenly less certain that he understood the country.

“Then nothing here is meant for me?”

The old woman smiled.

“I did not say that.”

She placed the basket of roots upon her shoulder.

“You asked the wrong question.”

And she walked away.

The traveller remained beside the path until nightfall.

For the first time, he listened carefully.

The country said nothing.

But the gate could be opened.

The path could be followed.

The branch could bear weight.

The cliff could be fallen from.

And as the darkness gathered, the traveller began to understand why this silence was more difficult than speech.

For if the country gave no instructions, then he would have to discover what was possible.

And if what was possible depended partly upon what he was—

then another creature might inhabit the same country differently.

The traveller looked down the path.

It did not ask him to follow.

Nevertheless, he went.

And the country remained silent.

When Does a Difference Make a Difference?: X. The World of Differences

We began with a simple thought.

Nothing happens without difference.

But by the end of our journey, the thought no longer seems simple.

The world is full of differences.

Yet differences do not all do the same thing.

Some alter physical processes.

Some constrain what can happen.

Some matter to living systems.

Some become perceptually available.

Some indicate.

Some become signs.

Some acquire meaning.

Some become concepts through which still other differences become consequential.

There is therefore no single way in which a difference makes a difference.

There are worlds within worlds.

A temperature difference can alter the state of water.

For a plant, a temperature difference can affect growth.

For an animal, it can become perceptually significant.

For a scientist, it can become a measurement.

For a community, it can become evidence of climate change.

The physical difference has not disappeared at any point.

But neither has it remained the same kind of difference.

Its consequences have multiplied.

This suggests that reality is not divided neatly into separate domains.

The physical, the biological, the perceptual, the social and the conceptual are not different universes.

They are different organisations of relations.

A physical difference can enter into a living process.

A living process can generate sensitivities.

Sensitivities can support indications.

Indications can become signs.

Signs can participate in meaning.

Meanings can become concepts.

Concepts can become practices.

Practices can alter the world in which new differences arise.

The direction is not one-way.

It is a circulation.

And this means that later forms do not simply replace earlier ones.

Meaning does not abolish mattering.

Concepts do not abolish perception.

Signs do not abolish indication.

Biology does not abolish physics.

The same difference can participate in several orders at once.

A sound is a physical event.

It may become a signal.

It may become a word.

It may become an argument.

It may become a memory.

The sound has not ceased to be physical.

But its possibilities have changed.

Perhaps this is the central lesson.

A difference does not acquire a new significance by leaving one world behind and entering another.

It acquires new possibilities by entering new relations.

And relations have histories.

The footprint has a history.

The animal has a history.

The practice of tracking has a history.

The concept of evidence has a history.

Each history changes what the difference can do.

This is why possibilities have histories too.

What can happen now depends partly upon what has already happened.

A distinction once introduced can become a category.

A category can become an institution.

An institution can become part of the environment.

The environment can then make new differences available.

The world we encounter is therefore partly inherited.

Not only its rocks and rivers.

Not only its organisms.

But its paths, categories, practices, signs and concepts.

We inherit landscapes of possibility.

And we alter them.

This is where the question of mattering becomes especially interesting.

We have learned that not every consequence is mattering.

Something matters when a difference becomes significant within the continuation or organisation of a living system.

But human worlds add another layer.

Through signs and concepts, we can make differences matter to one another.

We can decide that a distinction is important.

We can organise institutions around it.

We can teach it.

Record it.

Measure it.

Argue about it.

We can even discover that the distinctions through which we have organised our world are no longer adequate to the differences we encounter.

Then the conceptual landscape itself can change.

A new distinction can open possibilities that were previously difficult to see.

An old distinction can become a constraint.

A neglected difference can become consequential.

The world can appear different without having become a different physical world.

This is perhaps why we should be suspicious of both extremes.

The first says that meaning is already everywhere, waiting to be discovered in the physical world.

The second says that meaning is something minds simply impose upon an otherwise indifferent reality.

Our journey suggests something stranger.

The world gives us differences.

Organisms enter into relations with them.

Life makes some differences matter.

Sensitivity makes some differences available for differential response.

Indication makes some differences informative.

Signs make some differences stand for others.

Meaning makes those differences available for shared construal.

Concepts organise the resulting field of distinctions.

And through action, those distinctions can become part of the world itself.

Nothing has been added from outside.

Nothing was secretly present from the beginning.

Something has become possible.

That may be the deepest continuity running through everything we have explored.

The world does not begin with meanings.

It begins with differences.

But differences can enter into relations.

Relations can become organised.

Organisation can become sensitive.

Sensitivity can become signification.

Signification can become meaning.

Meaning can become conceptual organisation.

And conceptual organisation can alter the conditions under which future differences occur.

The process has no obvious starting point.

Nor does it have a final form.

Every achieved organisation becomes part of the conditions for something else.

Every distinction opens some possibilities and closes others.

Every new possibility can generate new differences.

Every new difference can begin another history.

Perhaps, then, the world is not best imagined as a collection of things with properties.

Nor as a blank field upon which significance is later projected.

Perhaps it is better understood as a history of differences becoming consequential.

Some differences vanish without a trace.

Some redirect a river.

Some sustain a life.

Some guide an organism.

Some leave a footprint.

Some become signs.

Some become words.

Some become concepts.

And some concepts eventually change what a world is capable of being.

We began by asking:

When does a difference make a difference?

Perhaps we can now answer.

A difference makes a difference whenever it enters into a relation that changes what can happen next.

But that answer contains a world of possibilities.

Because what can happen next depends upon what kind of relation has been formed.

And relations themselves can become transformed.

So perhaps the better question is not simply:

When does a difference make a difference?

It is:

What can a difference become?

That question has no final answer.

Fortunately.

For every answer is another difference.

And every difference may be the beginning of something new.

When Does a Difference Make a Difference?: IX. How Concepts Change What Matters

Meaning allows differences to become available for shared construal.

But concepts do something more.

They organise distinctions.

And when distinctions become organised, some differences begin to matter in new ways.

Consider a forest.

Physically, it contains trees, soil, water, organisms, light and countless differences among them.

But there is no single way of construing what those differences amount to.

The forest can become timber.

Habitat.

Wilderness.

Property.

Carbon store.

Sacred ground.

Recreation.

Each construal makes some differences more consequential than others.

If the forest is timber, the size and quality of trees may matter.

If it is habitat, the presence of particular species may matter.

If it is property, boundaries and ownership may matter.

If it is wilderness, human disturbance may matter.

The physical forest has not changed simply because we have changed the concept through which we construe it.

But the landscape of human action has.

This is the peculiar power of concepts.

They do not merely add information to experience.

They organise what counts as relevant.

A distinction that was previously invisible can become decisive.

A difference that previously passed unnoticed can become evidence.

A feature that once seemed incidental can become a reason for action.

The concept changes the field in which differences can make a difference.

This is why conceptual change can be consequential without being magical.

Suppose we begin to think of a stretch of river as an ecosystem rather than merely as water.

Nothing has been added to the river.

But new relations become visible.

Fish populations matter.

Nutrient cycles matter.

Upstream activity matters.

Seasonal variation matters.

The river can now be understood as part of a larger organisation.

The concept has not created these relations.

It has made them available within a particular way of construing the world.

And once they become available, action can change.

This is where concepts begin to acquire histories of their own.

A concept can be built into a practice.

A practice can be built into an institution.

An institution can alter the environment.

The altered environment can then make different things matter.

The process is circular.

Concepts change what we attend to.

What we attend to changes what we do.

What we do changes the conditions under which future differences occur.

Those differences then become available for further conceptualisation.

The landscape of mattering can therefore be transformed without the underlying world becoming a different world in every respect.

A species can become endangered because its habitat has changed.

But the concept endangered species can also change what counts as a relevant difference.

A population that might once have been merely declining can now become an object of measurement, concern, regulation and protection.

The concept does not cause the animal's biology.

It changes the social consequences of knowing about it.

This distinction matters.

Concepts do not manufacture physical significance out of nothing.

They reorganise the relations through which differences become consequential for human practices.

A medical category can change how symptoms are interpreted.

A legal category can change what an action permits or prohibits.

An economic category can change what counts as a resource.

A scientific category can change what counts as an observation.

The world does not become whatever the concept says it is.

But the concept can change which differences we build our actions around.

This is why conceptual systems can become powerful.

They provide pathways through which some differences travel further than others.

A difference can become a measurement.

A measurement can become a statistic.

A statistic can become a policy.

A policy can become an institution.

An institution can change the lives of people who never encountered the original measurement.

The difference has travelled.

And by the time it reaches them, it may no longer resemble the difference from which the process began.

This is perhaps one of the strangest properties of meaning.

A distinction can acquire consequences far beyond the circumstances in which it was first made.

And because concepts can be inherited, these consequences can persist.

We may continue to organise the world according to distinctions whose origins we have forgotten.

The conceptual landscape can therefore become part of the environment.

It can constrain.

It can afford.

It can make some possibilities visible and others difficult to see.

It can determine what counts as a problem before anyone has begun looking for a solution.

But this does not make concepts omnipotent.

They remain constrained by the world.

A concept cannot make a forest grow faster.

It cannot make a species exist.

It cannot make a river flow uphill.

What it can do is alter the human pathways through which physical differences become consequential.

And this brings us back to the central question.

When does a difference make a difference?

Sometimes because it changes a physical process.

Sometimes because it constrains a possibility.

Sometimes because it matters to a living system.

Sometimes because an organism becomes sensitive to it.

Sometimes because it indicates something else.

Sometimes because it stands for something.

And sometimes because a concept has taught a community that the difference matters.

The progression is not a ladder from primitive to advanced.

These forms coexist.

A physical difference can remain a physical difference while simultaneously becoming a matter of life, a perceptual distinction, an indication, a sign and a conceptual category.

The same difference can participate in several worlds at once.

Perhaps this is why the world can seem so full of meaning.

It is not that everything inherently means something.

It is that layers of organisation have accumulated around differences.

Physical systems.

Living systems.

Perceptual systems.

Semiotic systems.

Conceptual systems.

Each can make differences consequential in its own way.

And each can alter the conditions under which further differences become consequential.

We began with the simple observation that nothing happens without difference.

We can now see that the really interesting question was never simply whether differences exist.

It was how differences acquire trajectories.

Some disappear.

Some constrain.

Some matter.

Some indicate.

Some signify.

Some become concepts.

And some concepts eventually change what a whole community takes to matter.

That leaves one final question.

If the world is continually generating differences, and organised beings are continually turning some of them into consequences, meanings and concepts, then perhaps the deepest question is not:

What differences exist?

but:

What happens to differences once they begin to matter?

When Does a Difference Make a Difference?: VIII. Why Meaning Makes a Difference

A difference can stand for another.

That is already remarkable.

But why does it matter?

Why does meaning make a difference?

The answer is not simply that meaning allows us to communicate.

Communication is important.

But something more fundamental is happening.

Meaning changes what a difference can do.

A physical difference can affect a process.

A constraint can alter what is possible.

A living system can come to matter.

A difference can indicate something absent.

A sign can stand for something else.

But once a difference has meaning, it can enter a world of shared possibilities.

Consider a word such as danger.

The sound itself is only a physical event.

Within a language, however, it can make a situation available for a particular kind of construal.

Something can now be dangerous.

Someone can warn us about danger.

We can remember it.

Anticipate it.

Deny it.

Exaggerate it.

Argue about it.

The word has not merely indicated a condition.

It has made that condition available within a system of distinctions and relations.

And because the system is shared, the possibility can travel.

One person can make something available to another.

Something experienced here can become relevant there.

Something that happened yesterday can guide action tomorrow.

Something that has never happened can nevertheless become an object of thought.

Meaning therefore stretches the temporal and spatial reach of possibility.

This is one reason language is so powerful.

A physical constraint operates where it operates.

A sign can travel beyond the event that produced it.

A meaningful sign can travel even further.

It can be detached from the immediate situation and brought into new relations.

A word can be written down.

Copied.

Stored.

Quoted.

Translated.

Recombined.

It can become part of another sentence, another argument, another story.

The original event may disappear.

The meaning can remain available.

Meaning therefore gives differences a kind of historical mobility.

But it also gives them combinatorial power.

A single sign can participate in many relations.

Words can be combined into clauses.

Clauses into arguments.

Arguments into theories.

A small number of linguistic resources can therefore generate an enormous space of possible construals.

The sign has become productive.

It no longer merely points towards something.

It participates in the construction of possibilities that did not previously exist in that form.

This is why meaning cannot be reduced to information.

Information can tell us that something is the case.

Meaning allows us to ask what follows from it.

It allows us to relate it to other things.

To evaluate it.

To question it.

To imagine alternatives.

To formulate possibilities that are not yet actual.

Meaning therefore changes the temporal structure of action.

We can act on what is absent.

We can prepare for what has not happened.

We can organise ourselves around what might happen.

We can preserve what happened long ago.

A meaningful distinction can become part of the conditions for future action.

And here we encounter another feedback loop.

The world makes differences possible.

Living systems become sensitive to some of them.

Signs allow some differences to stand for others.

Meaning allows signs to participate in shared systems of construal.

Those systems organise practices.

Practices alter the world.

The altered world generates new differences.

And those differences become available for further meaning.

Meaning therefore does not sit on top of the world like a commentary.

It becomes part of the world's history.

This is why concepts can eventually change landscapes.

A meaningful distinction can become a rule.

A rule can become an institution.

An institution can alter behaviour.

Behaviour can alter material arrangements.

The material arrangements then become part of the environment in which new meanings arise.

Meaning has entered causality indirectly, through the practices it makes possible.

But we should be careful here.

Meaning does not make everything possible.

The physical world remains stubborn.

Words cannot remove gravity.

A description cannot dissolve a wall.

A concept cannot make every action feasible.

Meaning operates within constraints.

Indeed, perhaps meaning is powerful precisely because it operates through constraints.

A map does not create the terrain.

It makes some possibilities of movement available within the terrain.

A timetable does not create trains.

It organises possibilities for coordinating with them.

A law does not abolish physical reality.

It changes what people can legitimately do within a social order.

Meaning therefore does not replace affordance.

It creates new kinds of affordance.

A written instruction affords a different kind of action from a physical doorway.

A promise affords a different kind of expectation from a weather forecast.

A concept affords a different kind of inquiry from a perceptual distinction.

The meaningful world is therefore not a second world added to the physical one.

It is a new organisation of possibilities within the world.

And perhaps this is why meaning makes such a difference.

It allows differences to become available not merely to individual organisms, but to communities, histories and systems of practice.

It allows possibilities to be inherited without the original experience being inherited.

A child can learn a word for something that happened before the child was born.

A scientist can reason about an entity no human has directly encountered.

A society can organise itself around possibilities that exist only as legal, moral or political constructions.

Meaning allows a world to become cumulatively organised.

Each generation inherits not only a physical environment, but a landscape of distinctions.

Some are useful.

Some are misleading.

Some open possibilities.

Some close them.

Some have become so familiar that they are almost invisible.

The important point is that they have histories.

And once meanings have histories, they can evolve.

They can be extended.

Repurposed.

Combined.

Rejected.

Transformed.

The difference that means something today may mean something different tomorrow.

Meaning therefore does not end our story.

It accelerates it.

It gives becoming another medium.

The world contains differences.

Living systems become sensitive to them.

Signs make some differences stand for others.

Meaning makes those signs available for shared construal.

And shared construal can change what becomes possible next.

Which brings us to a curious reversal.

We began by asking how a difference can make a difference.

Now we can ask something more specific.

How can a way of construing difference change what matters?

That is where concepts enter the story.
