Trace, Depth, Form. What Thought Leaves Behind

Marco Raimondo

The thinking machine

The thinking machine in The Human Thinking Machine is not artificial. It is the human brain, the oldest and most complex machine we know.

The project starts from pen sketches made in everyday life, outside any artistic intention: traces of the brain at work before it becomes thought. The artistic act comes afterwards, in gathering, choosing and layering them.

This triptych follows a single fragment through three states, to look at one precise moment: when a thought takes shape, and what it leaves behind.

One fragment, three states

Trace is the original. Grey lines on white, lighter and darker, crossing without hierarchy. Everything is still present: no mark counts more than another. It is thought while it is still forming.

Form is derived from Trace. Many lines disappear; others thicken into a solid black that stands sharply against the white. Only what was chosen remains. The image is clearer, more legible, and also poorer. The thought has become conscious and has found a way to express itself.

So far this is a familiar story: from confusion to clarity, from sketch to work. We usually look only at the second term, the result.

Depth: the difference

Depth, at the centre, is not a third state added to the other two. It is obtained by subtracting Trace from Form.

The procedure is simple. Where Form is black, the black remains. Where Form is white, where form gave something up, the negative of Trace appears: the lines that had been left out, now light on a dark ground. Depth is literally the difference between the two outer panels.

This is why saying that meaning "happens between the images" is not a metaphor here. It is how the work is built. And the result does not depend on a filter applied from outside: it depends on that specific overlay of marks. Another fragment would produce another depth.

To decide is to lose

Every thought that takes shape loses something. Choosing a form means excluding others: details, directions, possibilities that were present in the trace and that the form did not keep.

Usually this loss stays invisible. Depth gives it an image. The details set aside are not erased: they have sunk into the dark, but they are still there. They are not waste. They are the ground the form stands on.

In this sense the triptych makes visible something that happens throughout my work. When I return to a sketch and rework it, the surface absorbs, filters and reflects back. Usually we see only what is reflected back. Here we also see what was filtered out.

An image seen before

I once saw my own heart projected on a large white screen: a network of grey lines, lighter and darker, branching out. It looked very much like what my hand has been drawing for years. Trace takes me back to that image.

The centre

The centre of the triptych is not a result but a difference. This is why the order is fixed: Trace, Depth, Form. The eye moves from the original to the form by passing through what the form has lost.

Meaning is not fixed in any of the three panels. It happens between them, and between the work and whoever is looking. The human thinking machine does not delete what it sets aside: it keeps it below the surface.
