Issue 40: Imperfect Traces

Humans have been leaving deliberate marks for a very long time. Before writing, before cities, and long before anything we would recognize as an institution, we were drawing animals on cave walls, carving forms into bone and stone, and making objects whose purpose seems to have extended beyond their immediate usefulness. Somewhere in this activity lies a transition that is difficult to reconstruct, but extraordinary once we consider what it involves: something perceived in the world, and retained in the mind, had acquired a material existence outside it.

I wonder whether one path towards this ability may have begun with marks that were not deliberately made at all. For a hunter, a footprint is evidence of something no longer there: from its shape, direction and relation to other traces, an absent animal can be reconstructed in the mind. The connection with representation is necessarily speculative, but prehistoric engravings of animal tracks make it more than a purely imaginative one. Studies of such engravings in Namibia have shown that Indigenous trackers can identify remarkably specific information in them, including species, sex and age group. People highly skilled at reading traces in the landscape were also choosing to reproduce those traces deliberately.

Whatever its origin, making an image introduces something different. The footprint is left by the animal; the drawing is left by someone thinking about the animal. The importance of the image may therefore lie less in whether we call it art than in the separation it makes possible: the animal and its representation can now occupy different places and different moments.

Once separated from what it depicts, the image can also be attended to in its own right. Its outline, proportions and relations can be emphasized, altered or recombined. This is familiar territory in photography: a person, a building or a tree remains recognizable inside the frame while simultaneously becoming shape, colour, depth and relation. The photograph can therefore produce meanings that were never present in quite the same way in the situation from which it was made.

Perhaps abstraction is one consequence of this separation. Rather than taking us away from reality, representation allows us to isolate elements and relationships that were harder to perceive while they remained embedded in it. What we call abstraction may be less a departure from reality than a different way of taking it apart.

Once a representation exists outside the mind, something more consequential becomes possible: it can be encountered by someone who was not present when the original experience occurred. An image can remain after its maker has left; an object can travel; a story can be repeated. Experience has acquired a form in which at least part of it can move between people and, eventually, between generations.

This changes where memory can reside. Something previously dependent on a living mind can now be deposited, however imperfectly, in the material world. But what is transmitted is never the original experience. Someone encountering an image has to interpret it; someone hearing a story has to reconstruct it. Even when the physical object survives unchanged, the mind encountering it is different, as are the context and the associations brought to it.

Writing would eventually make this problem particularly visible. A sequence of marks can survive almost perfectly for thousands of years while the language, metaphors and material world surrounding those marks change beyond recognition. We can still read ancient references to shepherds and sheep, for example, but we reconstruct them from within a culture in which most of us have never tended a flock. Writing can preserve the sign with extraordinary fidelity without preserving the world that gave the sign its meaning.

Every act of cultural transmission therefore contains an act of reconstruction. Even perfect copying cannot produce perfect continuity of meaning, because meaning does not reside entirely in the object being copied. It emerges again in the encounter between that object and another mind. Wherever reconstruction occurs, variation becomes possible: something can be emphasized, omitted, misunderstood or deliberately transformed.

What appears, from the perspective of communication, to be an imperfection may therefore be one of the conditions that allows representations to develop histories of their own.

Not every variation survives. Not every image is preserved, every story retold, or every interpretation carried forward. Some disappear with the people who made them; others persist long after the circumstances that first gave them meaning have vanished.

Why some representations persist is unlikely to have a simple answer. Usefulness, emotional force, memorability and the authority of those preserving them may all matter. Repetition itself may favour further repetition: what becomes familiar is easier to recognize, and what is already shared provides common ground for communication. Over time, this produces something more substantial than surviving objects or stories. It produces an inherited environment of meaning.

There is an obvious resemblance here to biological evolution, although the analogy has limits. Cultural forms can be copied, modified and selected, but their variation need not be random, and people can deliberately choose what to preserve or transform. Still, the underlying relationship is intriguing. For culture to accumulate, representations need continuity across generations; for culture to change, that continuity cannot be perfect. Preservation and variation are not opposing processes. Culture seems to require both.

This also helps explain how communities occupying the same physical world can gradually come to inhabit very different cultural ones. What one group repeatedly preserves may disappear in another. Different stories become familiar, different distinctions acquire importance, different images become recognizable. The material environment still matters, but layered over it is an inherited environment assembled from countless acts of selection and transmission.

Each new generation encounters that accumulation before it has had much opportunity to choose it. We are born into languages we did not invent, distinctions we did not devise and categories that can feel natural precisely because they were already waiting for us. What began as a way of placing something from the mind into the world has become part of the world into which subsequent minds are born. And that inheritance begins to participate in the perception from which new representations are made.

We do not encounter the world without preparation. By the time we are able to describe what we see, we have already learned names, distinctions, categories and associations from people who encountered it before us. This does not mean that culture determines perception completely, or that the physical world disappears behind language and symbols. It means that attention is partly learned. A hunter may perceive tracks where someone else sees disturbed soil. The sensory information may be available to both, but attention has been trained differently.

Images participate in the same process because every representation contains a selection. Photography makes this particularly explicit. A photograph isolates a position, a moment and a fragment of the visible world; when photographs accumulate across families, newspapers, archives, advertising, museums or social media, those selections accumulate with them. They do not merely preserve fragments of what people once saw. They help establish patterns in what is considered worth seeing and in how particular things are expected to look.

The direction of influence has therefore reversed without replacing the original one. We make representations because something in the world attracts our attention, but inherited representations also participate in directing attention back towards the world. What is repeatedly represented becomes easier to recognize; what has rarely been represented can remain difficult to notice even when it is directly in front of us.

We begin by making images of the world, but eventually we encounter the world partly through images, stories and categories made by people who came before us. The external world has not changed merely because we represented it. The conditions under which we perceive it have.

There is another consequence of this process that seems particularly relevant now. We usually treat the imperfections of communication as problems to be solved. We want greater fidelity, less ambiguity, faster transmission. Today it is possible to imagine taking this ambition considerably further: interfaces between brains and machines, increasingly precise forms of translation, perhaps eventually ways of transmitting aspects of experience that language can only approximate.

The advantages are easy to imagine. But if transmission has always required reconstruction, some of the inefficiencies we are trying to eliminate may also have been sources of variation. From the perspective of communication, these inefficiencies are noise. From the perspective of cultural evolution, they may also be variation.

Biology offers an uncomfortable analogy. A monoculture can be remarkably efficient because variation has been reduced, but that uniformity can become a vulnerability when circumstances change. Cultural diversity does not operate according to the same mechanisms, yet the comparison raises a question worth considering. If difference, reinterpretation and imperfect reproduction have contributed to the generative capacity of human culture, what happens when efficiency begins to remove them?

Perhaps perfect communication, if such a thing were possible, would simply allow us to understand one another better. But the history of representation suggests that some of what we call misunderstanding may belong to the process through which new meanings appear. What looks like noise at the level of communication may be variation at the level of culture.

The first marks humans learned to interpret were imperfect traces of things no longer there. Much of what followed—images, stories, languages, cultures—grew in the distance between an experience and its representation. We have spent thousands of years finding ways to narrow that distance. It seems worth asking what might disappear if we ever succeeded in closing it completely.
