Brief

Chris Lakin (2026-08-05) argues that boundaries—like a bacterium’s membrane with pores regulating nutrients and waste—create and preserve autonomy by maintaining separation from the environment. He claims boundaries provide causal distance (safety without physical distance), enabling closer interaction and cooperation between agents, so maintaining boundaries is essential to preserving autonomy.

Why it matters

On 2026-08-05, Chris Lakin uses a bacterium analogy: a membrane (boundary) with pores controls what comes in and out (nutrients and waste) and thus maintains the cell’s separation from its environment, creating autonomy.

Key details

  • Boundaries grant ‘causal distance’—safety without physical distance—so an agent can be protected from a threat while remaining physically close (author labels agent as blue and threat as red).
  • Because suitable boundaries enable safety and closer interaction, they allow agents to cooperate more; therefore, to preserve autonomy, preserve boundaries (don’t let membranes dissolve).

Why boundaries are essential: they create autonomy

Imagine a bacterium:
It has insides: its guts.

It has outsides: its environment.

And in between, a membrane.

The membrane is what attempts to control what comes in or goes out. For example, pores can guide nutrients and waste.
The membrane is what maintains the bacterium’s separation from the environment.

Boundaries can grant autonomy.
For a bacterium to stay autonomous, its membrane must not dissolve.

In general, for an agent to stay more autonomous, its boundaries must not dissolve.

(A bacterium is just one kind of agent, and “boundaries” are just another term for “membrane”.)

Suitable boundaries grant more autonomy.

Boundaries can provide safety without physical distance.
Let’s say an agent (blue) is endangered by a threat (red).

What could make blue safe?

One way is physical distance:

(Typically it’s harder for something to hurt you/cause effects on you if it’s far away.)

Another way is suitable boundaries:
Boundaries can provide “causal distance”.
In this way, suitable boundaries provide causal distance without physical distance.

Boundaries can allow cooperation.
When agents can rely on boundaries for safety (as opposed to relying on physical distance), they can interact more closely with each other.

And when agents interact more closely, they can cooperate more!

To preserve autonomy, preserve boundaries.
