There is a peculiar anachronism at work in how we think about reality. In physics, we still talk as if atoms were tiny marbles. In everyday life, we talk as if selves were little pilots steering our bodies through time. In both cases, we know better. And in both cases, we can’t seem to stop.
Consider the atom. Every chemistry textbook shows them as colorful spheres, electrons orbiting like planets. We teach children to build molecules with ball-and-stick models. Yet modern physics dismantled this picture a century ago. What we call ‘particles’ are really excitations in quantum fields—mathematical patterns, not things. They’re events masquerading as objects, processes dressed up as nouns.
The language persists because the maths doesn’t care what we call things, and humans need something to picture. ‘Electron’ is easier to say than ‘localised excitation in the electromagnetic field’.
The self enjoys a similar afterlife.
We speak of ‘finding yourself’ or ‘being true to yourself’ as if there were some stable entity to find or betray. We say ‘I’m not the same person I was ten years ago’ while simultaneously assuming enough continuity to take credit – or blame – for what that ‘previous person’ did.
But look closer. Strip away the story we tell about ourselves and what remains? Neural firing patterns. Memory fragments. Social roles shifting with context. The ‘you’ at work is not quite the ‘you’ at home, and neither is the ‘you’ from this morning’s dream. The self isn’t discovered so much as assembled, moment by moment, from available materials.
Like atoms, selves are inferred, not found.
This isn’t just philosophical hand-waving. It has practical teeth. When someone with dementia loses their memories, we wrestle with whether they’re ‘still themselves’. When we punish criminals, we assume the person in prison is meaningfully continuous with the person who committed the crime. Our entire legal and moral framework depends on selves being solid enough to bear responsibility.
And here’s the thing: it works. Mostly.
Just as chemistry functions perfectly well with its cartoon atoms, society functions with its fictional selves. The abstractions do real work. Atoms let us predict reactions without drowning in field equations. Selves let us navigate relationships, assign accountability, and plan futures without collapsing into existential vertigo.
The mistake isn’t using these abstractions. The mistake is forgetting that’s what they are.
Physics didn’t collapse when atoms dissolved into probability clouds. Chemistry students still balance equations; medicines still get synthesised. The practical utility survived the ontological revolution. Similarly, ethics won’t collapse if we admit selves are processes rather than things. We can still make promises, form relationships, and hold each other accountable.
What changes is the confusion.
Once you see both atoms and selves as useful fictions – pragmatic compressions of unmanageable complexity – certain puzzles dissolve. The ship of Theseus stops being paradoxical. Personal identity becomes a matter of degree rather than an all-or-nothing proposition. The hard problem of consciousness softens when you stop looking for the ghost in the machine.
We’re pattern-seeking creatures in a universe of flux. We freeze processes into things because things are easier to think about. We turn verbs into nouns because nouns fit better in our mental hands. This isn’t a bug in human cognition – it’s a feature. The problem comes when we forget we’re doing it.
So we end up in the peculiar position of defending little billiard balls in a field universe, and little inner captains in a processual mind, long after the evidence has moved on. We know atoms aren’t solid. We know selves aren’t fixed. Yet we persist in talking as if they were.
Perhaps that’s okay. Perhaps all language is a kind of useful betrayal of reality – solid enough to stand on, but not so solid we can’t revise it when needed.
The half-life of knowledge keeps ticking. Today’s insights become tomorrow’s anachronisms. But some fictions are too useful to abandon entirely. We just need to remember what they are: tools, not truths. Maps, not territories.
And every once in a while, it helps to check whether we’re still navigating by stars that went out long ago.
