The Emergence of Agency I — When Does Anything Have a Stake?

We usually begin talking about agency when something appears to do something.

An animal hunts. A person decides. A government acts. A machine executes a command. Agency seems to belong to things that can intervene in the world.

But perhaps this starts too late.

Before anything can act on a possibility, something has to make a difference between possibilities. And before a difference can guide action, some possibilities must matter more than others.

This suggests a simpler question:

When does anything have a stake?

A stone can fall. A river can erode its banks. A crystal can grow. None of these processes, by themselves, give us reason to say that anything is at stake. The difference between what happens and what might have happened belongs to our description, not necessarily to the system itself.

An organism is different.

A bacterium can encounter a concentration of sugar and move towards it. It can encounter a toxin and move away. The relevant distinction is not merely that the environment contains two different chemical conditions. The distinction is that the organism's continuing existence is differently related to them.

The environment contains differences.

For the organism, some of those differences matter.

This does not require consciousness. The bacterium need not experience sugar as desirable or toxin as unpleasant. Nothing needs to feel like anything. Mattering can be entirely biological before it becomes experiential.

This gives us a useful distinction between difference and mattering.

A difference is simply a difference between states.

Mattering begins when a difference is incorporated into the organisation of a system such that different states have different consequences for its continuation.

The distinction is subtle but important. A change in temperature is a physical difference. It becomes biologically significant when an organism's capacity to continue depends upon remaining within some range of temperatures.

The organism therefore does not merely occupy a world of differences. It participates in a world of consequences.

And consequences introduce possibility.

For a stone, there may be countless things that could happen next, but none of them is intrinsically preferable to another. For an organism, by contrast, some possible futures are compatible with continued organisation and others are not.

The future has acquired a structure.

This may be one of the earliest beginnings of agency—not because the organism chooses among futures, but because its organisation distinguishes futures according to what they mean for its continuation.

We should therefore be cautious about locating agency in decision-making.

Decision may be a very late form of agency.

At its origin, agency may be much simpler: a system whose own organisation makes a difference to what happens next.

The organism does not merely undergo events. Its state alters the possibilities available to it, while those possibilities feed back into its continued existence.

That creates a rudimentary loop:

what happens → matters to the organism → changes what the organism can do → changes what happens next.

Agency begins to appear not as a thing possessed by an organism, but as a relation between organisation and possibility.

This also changes how we should think about value.

Value need not begin as an idea, a preference, or a judgment. It can begin as a difference in consequence.

For something alive, there can be better and worse conditions before there is anyone capable of saying better or worse.

Life therefore introduces something remarkable into the physical world:

a future that matters to the system that is living it.

That may be the smallest possible stake.

And perhaps agency begins there—not when something first chooses what to do, but when what happens next becomes a matter of consequence for what it is.
