A fascination with systems

This comes from my general interest in computers.

I love systems: the way they work, what makes them tick, and how a small part can affect everything around it. A computer can look like a single object from the outside. Open it up, and there are layers of specialised parts, each relying on the others to do its job.

That has always felt close to the way my mind works. My interests do not sit in separate drawers. They send signals between one another. An idea from programming can change how I think about a drawing. A song can open a memory. Something I learn in therapy can alter the shape of an old dream. Those connections run both ways. Nothing exists in isolation.

The connections are sometimes inconvenient. They are also where much of the meaning lives.

The board

The image needed a circuit board, a central processor and the green tint usually associated with old technology. The final scene is darker and warmer than that description suggests.

At the centre is a bright circular processor. Copper and green traces radiate from it, carrying points of light through the board. Small components sit everywhere: capacitors, chips, coils and connectors. Some are sharply visible. Others fall out of focus as the board continues beyond what the eye can inspect.

The traces are the most important part. They turn a collection of objects into a system. Each line carries a signal somewhere else, and each junction offers another route through the design.

I like the sense that the board is alive with activity even when no particular event is taking place. Light travels. Parts wait for input. Something is always being passed along.

A part is not the whole

A component in isolation can be beautifully made and still be unable to do much. A processor without power is silent. Memory without a way to communicate with the rest of the machine has nowhere to send what it holds. A light without a circuit is only an object shaped like a light.

The function appears in the relationship.

That is a useful way to describe how I look at myself. I rarely encounter a trait, habit or difficulty on its own. I notice what it is connected to: what feeds it, what interrupts it, and what it sends elsewhere. A part of me becomes more understandable as I follow those connections through the wider system.

A tendency towards precision might be connected to curiosity, fear, care or all three. Withdrawal might be connected to exhaustion, self-protection and a deep fear of people. The same behaviour can carry different signals depending on the circuit around it.

Context does not excuse every effect. It does help me investigate one without pretending that it is the entire machine.

Signal and noise

Circuits are often described in terms of clean signals. A voltage is high or low. A message arrives or it does not. In practice, systems have noise. Components warm up. Connections degrade. A signal can be delayed, distorted or lost.

People are less tidy than diagrams.

I can be trying to communicate and still send something unclear. I can receive a message through the filter of an old fear and hear a different one. Sometimes I know that a reaction is larger than the immediate event, but I cannot yet find the earlier connection that amplified it.

That does not make the reaction imaginary. It means the signal has travelled through more of the system than I could see at first.

Part of therapy has been learning to trace those routes. Where did this feeling begin? What did it touch on the way here? Is it carrying information about the present, the past or both?

The answer is not always available. Following the path is still useful.

The people on the board

The circuit also makes me think about interdependence with other people.

No one builds a complicated system alone. There are designers, technicians, testers, maintainers and people who notice what the documentation missed. Each person contributes a specialised kind of attention. The finished board contains all of those decisions, even when the people themselves are no longer visible.

My own life is full of these hidden contributions. Someone teaches me a word. Someone listens long enough for me to finish a thought. Someone makes a piece of music that gives a feeling somewhere to go. Someone writes a tool I can use to turn an idea into a place.

The connections do not make me less myself. They are part of how I became a self capable of doing anything at all.

There is vulnerability in admitting that. A system that depends on connections can be interrupted by their loss. It can also be repaired, extended and supported. Dependence is not proof that a component is defective. It is a description of how the component participates in a larger design.

Embodied thought

In Source Code, I wrote about instructions: the ideas I can author, run and revise. The Circuit is about what happens when those instructions need a body.

Code can describe a calculation, but a processor has to carry it out. A drawing can express a feeling, but a hand, screen and set of tools have to make marks. A thought can be clear inside me and still need a voice, a message or a page before someone else can receive it.

The board gives thought somewhere physical to travel to, and something physical to travel through. It reminds me that expression is not only an act of will. It depends on materials, energy, time and connection.

When a part fails, the answer is not always to blame the part. I might need to check the power, the route, the interface or the assumptions built into the design.

A larger system

The Circuit represents more than a single thing. It may represent the structure of my mind, the network of people around me, or the way my interests keep crossing paths.

It does not need to choose.

The central processor is not a brain placed on a board. It is a point of coordination. The traces are not a map of every relationship I have. They are a way to show that meaning travels between places that might otherwise look unrelated.

The important part is not the glowing centre. It is the network that lets the glow reach everything else.

Keep the current moving

There are times when I want to isolate myself from the system: switch everything off, stop receiving signals and become a quiet component on a dark board. Rest can be necessary. So can a protected boundary.

But permanent isolation would also cut me off from the things that make life meaningful. Music, learning, friendship, making things and being understood all require some current to move between me and the world.

I am learning to distinguish an overloaded circuit from a dead one. When too much is passing through, I can reduce the load, add support or give the system time to cool. I do not have to destroy every connection to make the noise bearable.

The board keeps glowing in the dark.

Signals move through the traces. Separate parts meet at their junctions. Somewhere in that movement, a system becomes more than its components.
