After Possibility had entered the world, the Things began to change.
This did not surprise them.
Things had always changed.
What surprised them was that they began to notice it.
The Tree noticed first.
One morning it discovered that one of its branches was longer than it had been the previous year.
The Bird noticed that its feathers had changed.
The Stone noticed that it had become smoother.
The River noticed nothing in particular, which was one of the reasons the others trusted it.
They began to ask an old question in a new way.
“If we change,” said the Bird, “how can we still be ourselves?”
The Stone considered this.
“I am still a Stone.”
“You were smaller before.”
“I am still a Stone.”
“You were rougher.”
“I am still a Stone.”
“You have been shaped by the River.”
The Stone looked at the River.
“I am still a Stone.”
The River said nothing.
The Bird was dissatisfied.
“You keep saying that you are the same.”
“Yes.”
“But you have changed.”
“Yes.”
“How can both be true?”
The Stone had no answer.
The Things decided to ask the River.
They found it further downstream than usual.
“You are the oldest of us,” said the Tree.
“I am not the oldest,” said the River.
“Older than us, then.”
“Perhaps.”
“You have changed your course.”
“Yes.”
“You have carried away stones.”
“Yes.”
“You have received new waters from tributaries.”
“Yes.”
“You have sometimes flooded and sometimes become shallow.”
“Yes.”
“And yet you remain the River.”
“Yes.”
The Bird became impatient.
“How?”
The River flowed for a while before answering.
“You are asking how I remain the same while everything in me changes.”
“Yes.”
“That is because you are imagining sameness as the absence of change.”
The Things looked at one another.
“What else could it be?”
The River answered:
“A pattern can remain while what participates in the pattern changes.”
The Things did not immediately understand.
So the River gave them a whirlpool.
The whirlpool appeared where the River narrowed between two rocks.
The Things watched it turn.
Round and round it went.
The water entering it was never the same water for long.
Yet the whirlpool remained.
“How long has it been there?” asked the Tree.
“Long enough for you to notice it.”
“How long will it remain?”
“As long as the conditions that sustain it remain.”
The Bird flew closer.
“But the water is always changing.”
“Yes.”
“Then the whirlpool is not the water.”
“No.”
“Is it the rocks?”
“No.”
“Then what is it?”
The River smiled.
“You are beginning to ask better questions.”
The whirlpool continued turning.
The Things watched it persist through change.
For the first time, they saw that persistence did not have to mean remaining untouched.
A thing could remain itself by changing in an organised way.
This discovery unsettled them.
They had always imagined change as something that happened to a Thing.
Now they began to suspect that some Things existed only because change kept happening in the right way.
The Tree took this discovery very seriously.
It had always thought of itself as something that grew.
Now it wondered whether growth was something that happened to it—or whether growth was part of what it meant to be the Tree.
It looked at its leaves.
They appeared.
They unfolded.
They gathered light.
They withered.
They fell.
New leaves came.
The Tree remained.
It looked at its trunk.
Year after year it thickened.
It looked at its roots.
They extended into the earth.
It looked at the creatures living among its branches.
Some arrived.
Some departed.
The Tree understood that none of these things could be separated completely from what it was.
Its being was not hidden underneath its becoming.
Its being was the pattern of its becoming.
The Tree was pleased with this discovery.
Then a storm came.
The storm was enormous.
Wind tore through the forest.
Branches broke.
Trees bent.
Some fell.
The River rose.
The Tree held.
When the storm had passed, the Tree looked very different.
One great branch was gone.
Several smaller branches had been broken.
Its bark was torn.
The Bird's nest had disappeared.
The Tree was shaken.
“Am I still the same Tree?”
The River answered from below.
“That depends.”
“On what?”
“On what you mean by ‘same’.”
The Tree did not like this answer.
“I mean: am I still me?”
The River flowed around the roots.
“Yes.”
“But I have changed.”
“Yes.”
“Then why am I still me?”
“Because the pattern that makes you what you are has changed without yet becoming another pattern.”
The Tree looked at the broken branch.
“So identity has limits.”
“Yes.”
“And change has limits.”
“Yes.”
“What happens when the pattern changes too much?”
The River was quiet.
“Then something else may begin.”
The Tree considered this.
It was not entirely comforting.
But it was true.
Not long afterwards, the Stone disappeared.
The others searched for it.
Eventually they found it downstream.
It had been carried away by the River.
It was no longer beside the clearing.
“This is unacceptable,” said the Bird.
The River said nothing.
The Stone was eventually found lodged among other stones.
“You have moved,” said the Tree.
“Yes.”
“You are no longer where you were.”
“No.”
“Then are you still the same Stone?”
The Stone looked at itself.
It was the same shape, although somewhat smoother.
“I think so.”
The River said:
“Your location was part of your history, not the whole of your identity.”
The Stone was relieved.
Then it noticed something.
The place where it had once rested was now empty.
A small stream had begun to flow through the space.
New possibilities had appeared.
The Stone realised that becoming was not merely something that happened to a Thing.
Its own changes altered the world in which other things could become.
The Things began to notice this everywhere.
A fallen tree became shelter.
The shelter became a home.
The home altered the behaviour of creatures.
Their behaviour changed the forest.
The forest changed the River.
The River changed the valley.
The valley changed the creatures.
The Things had once imagined change as a sequence:
one Thing changes,
then another Thing changes,
then another.
Now they saw something different.
Each becoming altered the conditions of further becoming.
The present was not simply the point between a finished past and an already determined future.
It was a place from which possibilities opened.
And some possibilities closed.
One day a seed fell from a tree.
It landed in poor soil.
The Bird saw it.
“That seed will become a Tree.”
“Perhaps,” said the River.
“Isn't it a Tree already?”
“No.”
“But it can become one.”
“Yes.”
“So it will.”
“Not necessarily.”
The Bird was puzzled.
“What stops it?”
“The soil.”
“The rain.”
“The light.”
“The creatures that may eat it.”
“The seasons.”
“Many things.”
“But if it has the potential to become a Tree, shouldn't it become one?”
The River flowed around the seed.
“Potential is not a promise.”
The seed remained where it had fallen.
Rain came.
Then drought.
The seed did not grow.
Eventually an animal ate it.
The Bird looked disappointed.
“But it could have become a Tree.”
“Yes.”
“And it didn't.”
“No.”
The River continued downstream.
The Bird followed.
“What happened to its potential?”
“It was never a thing stored inside the seed.”
“Then what was it?”
“A possibility.”
“Where?”
The River answered:
“In the relation between the seed and a world in which it might have grown.”
The Bird was silent.
Possibility, it seemed, did not belong entirely to Things.
Another seed fell.
This one landed in good soil.
Rain came.
Sunlight followed.
Roots emerged.
The seed opened.
A shoot appeared.
The Bird watched.
“This one will become a Tree.”
“Perhaps.”
The Bird looked at the River suspiciously.
“You are going to say ‘not necessarily’ again.”
“I might.”
But this seed grew.
Its roots entered the soil.
Its stem rose.
Its leaves unfolded.
Years passed.
It became a young tree.
Then an older tree.
The Bird eventually built a nest in it.
The Tree was pleased.
“You see?” said the Bird to the River. “It became what it could become.”
The River replied:
“No.”
The Bird frowned.
“What do you mean?”
“It became what became possible.”
The Bird looked at the Tree.
The Tree looked at the Bird.
Neither knew what to say.
As the years passed, the Things began to discover that their futures were not waiting for them like hidden rooms.
There were paths.
There were constraints.
There were tendencies.
There were opportunities.
But there was no single road laid down in advance.
The River could change course.
The Tree could break.
The Bird could migrate.
The Stone could be carried downstream.
A forest could burn and become grassland.
Grassland could become forest again.
Every change altered what could happen next.
The world was not a machine carrying out a plan.
Nor was it chaos.
It was something stranger.
The Things were becoming within conditions that mattered without being completely determined by them.
Then the Things encountered Time.
Time was not a Thing.
It had no shape.
It could not be held.
It could not be placed beside another Thing.
Yet it was always there.
At first the Things thought Time was simply what carried them from one moment to another.
But then they discovered something peculiar.
The past did not disappear completely.
The Tree carried its past in its rings.
The River carried its past in its channels.
The Stone carried its past in its worn surface.
The forest carried its past in its soil.
The Bird carried its past in the paths it had learned.
The present was not empty of what had come before.
It was thick with it.
One evening, the Bird sang.
The first note sounded.
Then the second.
Then the third.
A Thing listening from far away said:
“Why is the first note important? It has already ended.”
The Bird answered:
“Because the second note comes after it.”
“That cannot be enough.”
“It is.”
The Thing listened.
The second note changed what the first had meant.
The third changed what the second had meant.
The whole song became something that no individual note had been.
The Thing realised that the past could remain active without remaining present in the same form.
A melody was not a collection of notes.
It was a pattern that became itself through time.
The Things were beginning to understand.
Much later, the Stone asked the River:
“Does the future already exist?”
The River laughed.
“You ask strange questions.”
“Does it?”
“No.”
“Then how do you know where you are going?”
“I don't.”
“But you flow towards the sea.”
“Yes.”
“So you must have a destination.”
“A direction is not a destination.”
The Stone thought about this.
“Then what determines your course?”
“Many things.”
“The land?”
“Yes.”
“The rain?”
“Yes.”
“The mountains?”
“Yes.”
“The tributaries?”
“Yes.”
“Your own previous course?”
“Yes.”
“Can you change?”
“Yes.”
“Can you flow anywhere?”
“No.”
The Stone understood.
The River's future was neither predetermined nor unconstrained.
Its possibilities were structured.
The relations through which it existed opened some paths and closed others.
But within those conditions, something new could happen.
The River could become different.
And when it did, the possibilities of everything downstream would change.
The Things began to see that this was true of themselves.
A relation that changed could change a Thing's possibilities.
A new neighbour could alter a creature's behaviour.
A changed climate could alter a forest.
A new path through the forest could alter where creatures travelled.
A new word could alter what could be thought.
A new idea could alter what questions could be asked.
A new relation could make a possibility visible that had not previously been available.
And when a possibility became actual, it changed the field again.
Possibility could create possibility.
The world was becoming a history of its own transformations.
One day, the River was asked a final question.
“You told us that a Thing can persist through change.”
“Yes.”
“You told us that becoming can be organised.”
“Yes.”
“You told us that possibility depends upon relations.”
“Yes.”
“And you told us that the future is not already waiting for us.”
“Yes.”
The Things gathered around.
“Then what is a Thing?”
The River looked at them.
“A Thing,” it said, “is sometimes what a becoming looks like when it has learned how to persist.”
The Things were silent.
“And what is becoming?”
The River flowed on.
“A becoming is sometimes what a Thing looks like when you remember that it has a history.”
The Things considered this.
It was not an answer that separated the two.
It was an answer that made the separation less necessary.
That evening, the River changed its course.
Not by much.
A few stones shifted.
A bank gave way.
A new channel opened.
The River began to flow through it.
The Things watched.
“Is that still the River?”
The River answered:
“I don't know yet.”
The Things were astonished.
“You don't know?”
“No.”
“How can you not know what you are?”
The River flowed through the new channel.
“Because I am becoming it.”
And as the water moved into places where it had never flowed before, the old channel began to dry.
The landscape changed.
The creatures changed their paths.
The plants changed where they could grow.
New relations formed.
New possibilities appeared.
And somewhere beyond the bend, something that had never existed before became possible.
The River did not know what it would be.
Neither did the Things.
For the first time, they understood that this was not a failure of knowledge.
It was part of what it meant for the world to become.
And so the Things continued.
Not remaining what they were.
Not ceasing to be themselves.
But becoming.
