The people of the First Country had begun to speak differently about possibility.
They had learned that possibility belonged to the world.
A door could leave a passage open.
A road could leave a journey open.
A river could leave a crossing open.
The shape of things, and the relations between them, determined what could happen.
But then another question began to trouble them.
What, exactly, did it mean to say that something had a potential?
The question first arose in the King's garden.
There was an old gardener who had planted a seed beneath the soil.
“This seed will become a tree,” he said.
The youngest philosopher looked at the earth.
“Is the tree already there?”
The gardener laughed.
“No.”
“Then where is it?”
“In the seed.”
She knelt beside the soil.
She dug carefully until she found the seed.
She held it in her hand.
It was small.
There was no miniature tree inside it.
No tiny branches.
No leaves.
No hidden trunk.
Yet everyone in the garden still spoke as though the tree were somehow already there.
She carried the seed to the oldest philosopher.
“If the tree is not inside the seed,” she asked, “what does it mean to say that the seed has the potential to become a tree?”
The old philosopher took the seed from her.
“Let us see.”
He placed it upon a stone.
Nothing happened.
He placed it in dry sand.
Nothing happened.
He placed it beneath the shade of a wall.
Nothing happened.
Then he returned it to the garden.
The gardener planted it again.
He gave it water.
The sun warmed the soil.
Days passed.
The seed changed.
A small root appeared.
Then a shoot.
Then leaves.
The youngest philosopher watched.
“Was the tree hidden in the seed after all?”
The old philosopher shook his head.
“Look around.”
She looked.
The soil.
The water.
The sunlight.
The air.
The warmth.
The passing of time.
The gardener's care.
The creatures living beneath the ground.
The seed was not becoming a tree alone.
It was becoming a tree in a world.
The philosopher understood.
The potential had never been a little future object stored inside the seed.
It had belonged to the seed in relation to everything around it.
The old philosopher pointed toward the garden wall.
“Change the soil.”
The youngest philosopher imagined the seed lying in dry stone.
“Then it may not grow.”
“Change the water.”
“It may wither.”
“Change the temperature.”
“It may cease to develop.”
“Remove the light.”
“Its becoming changes again.”
The old philosopher nodded.
“Then where is its potential?”
The youngest philosopher looked at the seedling.
“Not simply inside it.”
The gardener overheard them.
“Where, then?”
She touched the young stem.
“In the relation between what it is and the world in which it grows.”
The news spread through the country.
Soon people began testing the idea.
A swimmer came to the river.
He was strong and knew how to swim.
But the river had dried.
He stood upon the stones.
His ability remained.
Yet there was no swimming.
The youngest philosopher watched him.
“Does he still have the potential to swim?”
The old philosopher considered this.
“He has the capacity.”
“But no possibility?”
“Not here.”
The swimmer looked at the empty riverbed.
Nothing about his body had changed.
The world had changed around him.
His readiness remained, but the opportunity had disappeared.
Later they came to a deep lake.
The water was clear and calm.
Swimming was possible.
But beside the lake stood a child who had never learned.
The water opened a possibility.
The child could not yet take it up.
The possibility was present.
The relevant potential was not.
The youngest philosopher began to see that the two words had been describing different things all along.
Possibility belonged to the field.
Potential belonged to the participant within the field.
Neither was sufficient by itself.
An open door did not make everyone capable of passing through it.
A capable traveller did not make every door open.
A river did not make every creature a swimmer.
A swimmer did not create a river.
The two had to meet.
But even then, the meeting was not guaranteed.
For the world could change.
The participant could change.
The relations between them could change.
And with every change, what was possible for that participant could change as well.
One afternoon, the King brought a strange machine to the Hall of Inventions.
It was the first of its kind in the First Country.
It could carry messages farther than a horse could travel.
The people gathered around it.
The machine made something possible that had never been possible before.
But not everyone could use it.
Some understood it immediately.
Some needed to learn.
Some could not reach it.
Some were forbidden to touch it.
Some had no reason to use it at all.
The machine had changed the field of possibility.
But it had not given every participant the same potential.
The youngest philosopher thought about this.
“When a new possibility appears,” she said, “it does not automatically become an achievement.”
The old philosopher nodded.
“It changes the field in which potential can operate.”
“And if someone learns to use the machine?”
“Then the participant's relation to the field changes.”
“And if the machine disappears?”
“The possibility changes again.”
She was beginning to understand something even more subtle.
Potential did not have to change because the participant itself had changed.
Sometimes the world changed around it.
The locked door had not made the traveller less able to walk.
The opening of the door had not given him the ability to walk.
It had changed the relation through which his existing ability could be exercised.
The youngest philosopher returned to the garden.
She found the seedling had grown taller.
She touched its leaves.
“What does this tree have the potential to become?”
The gardener smiled.
“That depends.”
“Upon what?”
“Upon the world.”
She looked around.
The tree had space to grow.
The soil was rich.
The river still flowed.
Birds nested in its branches.
Bees visited its flowers.
Children rested beneath its shade.
The tree's future was not written inside it.
Nor was it arbitrary.
It arose from the relations in which the tree participated.
The youngest philosopher remembered the great sequence they had discovered:
RELATION → DIFFERENCE → CONSTRAINT → POSSIBILITY → BECOMING → NEW RELATION
She had once wondered whether potential should be added to the sequence.
Now she saw that this was the wrong question.
Potential was not another step in the journey.
It appeared wherever a participant stood within a field of possibility.
She wrote in the earth:
POSSIBILITY
Then:
What does the world leave open?
Beside it she wrote:
POTENTIAL
What can this participant take up within that opening?
She looked at the two questions.
They faced one another.
The first looked outward, toward the field.
The second looked from the participant into the field.
Neither could be reduced to the other.
And neither was yet becoming.
For possibility was not an achievement.
Potential was not an achievement.
Both concerned what had not yet happened.
But they concerned it from different sides.
The world said:
This remains open.
The participant answered:
This I may be able to take up.
And somewhere between those two statements, the future began to acquire a path.
The youngest philosopher walked to the river.
The swimmer was there again.
This time the water had returned.
He stepped into it.
His capacity had not created the river.
The river had not created his capacity.
But now the two stood in a relation through which swimming could occur.
He pushed away from the bank.
The possibility became an action.
The action became an event.
The event changed the swimmer.
It also changed the river's relation to him.
And the youngest philosopher realised that this was why neither possibility nor potential could be the whole story.
Something happened when they met.
Something became actual.
And what became actual could change the relations from which the next possibilities arose.
That evening, the philosophers gathered beneath the growing tree.
The old philosopher looked at the seedling.
“Do you still think the tree was hidden inside the seed?”
The youngest philosopher smiled.
“No.”
“Then what did the seed have?”
She thought for a long time.
“At first I would have said a potential.”
“And now?”
She looked at the tree, the soil, the river, the sky.
“It had a readiness for certain forms of becoming, constituted through its relations with the world.”
The old philosopher nodded.
“And does that readiness stay the same?”
“No.”
“Why?”
“Because the relations change.”
“And can the relations change without the seed itself changing?”
She thought of the locked door.
“Yes.”
The old philosopher smiled.
“Then we have learned something important.”
The youngest philosopher looked at him.
“What?”
He pointed toward the path leading from the garden.
“Potential is not what lies before becoming.”
She followed his gaze.
“Then what is it?”
He looked at the seedling.
“Perhaps it is what becomes visible when a participant encounters a possibility.”
The wind moved through the leaves.
The tree had once been a seed.
The seed had once been nothing that anyone would have called a tree.
And yet the future had not been hidden inside it.
It had emerged through the changing relations between the seed and its world.
The youngest philosopher stood beneath the branches.
Then she asked the question that seemed to open another door:
What happens when potential meets possibility?
