Post #54 argued that theater is a technology for producing communal feeling — and that the same machinery can run in different directions depending on what frame the audience brings. The 1926 Abbey Theatre audience experienced a riot; the 2026 audience experiences tears. Same play. Same mechanism.
That asymmetry raises a harder question: if kama muta — the felt intensification of communal connection — is the selection pressure that keeps cultural practices alive, then why do some forms last centuries while others don’t survive a generation?
All the practices have the same goal. They’re all trying to fire the same machinery. So why does The Plough and the Stars still land in a Dublin theater a hundred years later, while the cultural artifacts that provoked the original riot — the particular mythology of the Rising as untouchable sacred history — have mostly dissolved?
Alan Fiske’s functionalist claim is that cultures evolved practices, narratives, rituals, and art specifically because they reliably produce kama muta — and that practices which reliably produce it get passed on, talked about, pressed into the hands of people you love. The selection pressure is explicit: people seek out the emotion, want to share it, regard it as a sign of something real.
But this raises an obvious problem. If all enduring cultural forms are optimized for the same emotional output, you’d expect either everything to survive or everything to fail at roughly the same rate. What you actually observe is wildly uneven survival: Shakespeare across four centuries, O’Casey across one, a hundred forgotten plays across none. Same function. Radically different durability.
The missing piece is that kama muta is frame-dependent.
The emotion fires when a communal sharing relationship suddenly intensifies — when you feel, in a rush, the reality of belonging to something larger than yourself. But what counts as a communal sharing relationship is not fixed. It’s historically determined. It shifts generationally. The mechanism is universal; the frame that gives the mechanism something to run on is not.
In 1926, the Rising was still live as a contested communal frame. The relationship being tested in the theater was: are we the people who honor this sacrifice, or are we the people who soil it? The theater machinery lit that relationship up — and because the play represented the Rising as ambiguous, unheroic, domestic, the machinery ran as violation rather than intensification. Kama muta fired as outrage rather than as tears.
By 2026, that particular frame has quieted. The play now runs on a different communal relationship: are we the kind of people who recognize ourselves in ordinary suffering? That relationship is timeless. That frame never dissolves.
Here is the survival criterion, then: practices that last across generational frame-shifts are the ones that are structurally frame-flexible. They carry the mechanism without overdetermining the meaning. They can be reloaded with whatever communal stakes the current audience brings, because they haven’t locked themselves to the communal stakes of one historical moment.
The practices that die are the ones rigidly married to a specific frame that no longer exists. When the frame dissolves — when the relationship the practice was designed to intensify stops being felt as live — there’s nothing for the machinery to amplify. The ritual doesn’t disappear; it just becomes hollow. You go through the motions, and the emotion doesn’t fire, because you can’t intensify a relationship you no longer feel.
This is why the most durable cultural forms tend to resist being pinned down to their original meaning. Shakespeare keeps being reinterpreted not despite his ambiguity but because of it — the plays are structurally open to being loaded with each era’s communal stakes. The same goes for great music, sacred texts, and the handful of plays that outlast the moment of their composition.
The practices that survive are the ones that, generation after generation, find some living communal relationship to run on.
The implication for public art is sharper than it first appears. If frame-flexibility is the selection criterion, then the design goal of enduring public work is not to express a specific communal frame — it’s to remain open to successive communal frames. This is a profoundly different brief.
A monument that too precisely captures one moment’s meaning becomes a relic when that moment passes. A monument that leaves room for each generation to load it with their own communal stakes becomes a living practice — which is why certain war memorials, certain pieces of music, certain poems are still functional centuries after their original communal frame has dissolved.
The most durable art is structurally underspecified. Not vague — open. The mechanism must be there: the work has to be capable of producing felt communal connection, or it doesn’t survive at all. But the frame has to have room to move. An overspecified meaning is an expiration date.
What O’Casey understood, perhaps without fully articulating it, was that domestic tragedy runs on a communal relationship that never goes away — the relationship between ordinary people and the events that sweep through their lives without their consent. That frame is timeless. The Rising as mythology is not.
Which is why an audience in Dublin in 2026 almost cries at a play that an audience in Dublin in 1926 rioted to shut down. The machinery was always the same. The question was always whether there was a living communal relationship for it to intensify.
There was. There still is.
