A Story of Systems

What Became Possible

Opening

The Window

Begin reading

The moth keeps striking the window.

Outside, the evening is open. There are leaves to settle under, damp places, other moths. The insect can see the world it belongs to. Between its body and that world is something its ancestors never had to understand: a surface that is solid and looks like air.

It climbs a little. Tries again. Its wings make a sound too small to reach the other end of the room.

A child notices.

What happens next is ordinary enough to miss. The child finds a glass and a piece of paper. There is a brief, awkward pursuit. The glass knocks against the pane. The moth folds itself into a corner, then suddenly fills the glass with wings. The paper slides underneath.

Now the child is carrying a small frightened animal toward a door.

We will leave them there for a while.

There is a great deal to account for before they reach it.

The glass, for example. The wings. The fact that there is an outside with air in it. The muscular precision that holds the paper against the rim without crushing anything. And somewhere behind the child’s eyes, a recognition: that small life over there is having trouble, and I can do something about it.

No atom in the room could do that alone.

Once, there were no atoms.

The history between those two facts is our story. It contains fires larger than worlds, oceans without fish, an atmosphere made dangerous by life, and animals whose long history of moving through darkness helped shape their senses. It contains accidents that erased entire futures. It also contains meetings after which the things that met could never quite be understood separately again.

We call a collection of interacting parts a system. The word is plain. What it describes can be startling. A pile of parts becomes something with a way of behaving that depends on how the parts are joined. Separate a heart into its molecules and every molecule is still there. The heartbeat is gone.

Across this history, the joining changes. Gravity gathers. Chemistry binds. Cells inherit. Animals learn. People agree, argue, remember, and sometimes help one another carry what would otherwise be too heavy.

Each kind of joining makes a different world possible.

None of this guarantees a child, a moth, or kindness. Almost all of the universe has gone its entire history without any of them. But here, on one small planet, they have happened. The child is holding the glass carefully. The paper is beginning to bend.

To understand how much is being carried, we have to go back beyond the first thing that could be held.
