An organism does not live in the world as we describe it.
It lives in the world that its organisation makes possible.
A bacterium encounters chemicals, but only some chemical differences are relevant to what it can do. A plant encounters sunlight, gravity, water and countless other physical conditions, but these do not all enter equally into its life. A spider encounters a space in which vibrations, surfaces and gaps have consequences that would be invisible to us.
The organism therefore does not simply inhabit an environment.
It inhabits a field of possibilities.
This does not mean that the organism constructs an imaginary world. The external conditions are real. What changes is the relation between those conditions and the organism's capacities.
Water affords something to a fish that it does not afford to a terrestrial mammal.
A vertical surface affords something to a spider that it does not afford to a tree.
A particular wavelength of light can afford photosynthesis to a plant without being perceived as light at all.
An affordance, in this broad sense, is not a property of the object alone. Nor is it a projection of the organism alone.
It is a relation between what exists and what the organism can do.
This gives us another way of understanding the emergence of agency.
An organism's possibilities are not unlimited. Its structure selects among the possibilities offered by its environment.
A membrane permits some exchanges and prevents others. A digestive system makes some substances usable and others irrelevant or harmful. Muscles, limbs, roots, wings and sensory systems each open some possibilities while closing others.
To be an organism is therefore already to inhabit a structured space of possible action.
And this space is not fixed.
An organism changes as it acts.
A plant's roots alter the soil around them. A beaver changes a river. A spider changes its surroundings by constructing a web. An animal's repeated movements can turn a previously irrelevant feature of its environment into a usable resource.
The organism does not merely respond to its world.
It helps to make the world it can subsequently respond to.
This creates a reciprocal relation:
the environment constrains what the organism can do, while the organism changes the conditions under which it can act.
Agency therefore cannot be located entirely inside the organism.
Nor can it be located entirely outside it.
It arises in the relation between the two.
This also clarifies the connection between mattering and possibility that we began with.
Something matters to an organism partly because it changes what the organism can afford to do.
Food matters because it can sustain future activity. Shelter matters because it changes the possibilities of survival. A threat matters because it constrains the organism's future.
Mattering is therefore not simply a reaction to the present.
It is oriented, however primitively, toward what can happen next.
An organism lives in a world of affordances because it lives in a world of possible futures.
And those futures are not abstract possibilities. They are possibilities for this organism.
The distinction is important.
There is the possibility of climbing a tree.
And there is the possibility of climbing a tree for a squirrel.
The first is a statement about the world.
The second describes a relation between the world and an organism's capacities.
This may be the beginning of perspective in a very elementary sense. Not consciousness, not representation, not a private point of view—but a world organised according to what is possible here, for this system.
Agency begins to look less like a power added to life and more like a consequence of being alive.
To live is to be constrained.
To be constrained is to have some possibilities and not others.
And to have possibilities that differ in their consequences is already to have something at stake.
The organism inhabits, therefore, not simply a world of things, but a world of what it can afford to do.
And that world is continually changing because the organism is changing it.
Agency may begin precisely in that circularity:
the organism acts upon a world of possibilities, and in acting, changes the possibilities upon which it can act.
