In January 1926, a theatrical premiere in Dublin ended in chaos. Audience members shouted down the actors. Hecklers filled the hall. W.B. Yeats came out on stage to address the crowd, famously telling them they had disgraced themselves.
The play was The Plough and the Stars by Sean O’Casey. Its offense, in the eyes of those who rioted, was depicting the Easter Rising through the lives of ordinary tenement people — drinkers, prostitutes, squabbling families — rather than as the sacred national myth it was supposed to represent. The flag of the Irish Republic appeared, briefly, inside a pub. That was enough.
This past week, on the play’s centenary, audiences sat in the same city and watched the same play. Some of them were moved to tears.
Both responses were sincere. Both were to the same work. What changed?
There’s a psychological framework for what happened in that theater — both times.
Researchers call it kama muta, from the Sanskrit for “being moved by love.” It describes a specific emotion: the sudden felt sense of communal closeness, oneness, belonging. It’s evoked not by beauty exactly, but by perceived intensification of communal sharing — the moment when the membrane between self and community thins. Physiologically, it presents as warmth in the chest, tears, goosebumps, a catch in the throat. Behaviorally, according to a 2025 postural study, it stabilizes the body. When you’re moved, you go still.
The 1926 audience went the opposite direction. They shouted. They stormed. They moved.
What distinguishes the two responses isn’t the presence or absence of kama muta; it’s the direction of the disruption the play produced. Kama muta theory locates the emotion in the sudden intensification of communal sharing relationships. Its opposite — the feeling that a communal bond is being violated, mocked, desecrated — produces something more like moral outrage. The same social circuitry, running backward.
In 1926, the communal frame was still hot. The Rising was barely a decade past. The martyrs were recent. The Republic was new and fragile and contested. Into this context, O’Casey brought tenement irony — characters who drink while the rebellion burns, who squabble about furniture, who are neither heroic nor villainous but simply human in the ordinary, unspectacular way that history never quite lionizes. To an audience whose communal identity was still partly structured around the sacred narrative of the Rising, this felt like violation. The machinery of theater — which is precisely designed to intensify communal feeling — ran backward, amplifying outrage instead of connection.
A century is long enough for the frame to cool.
By 2026, the nationalist scaffolding around the Easter Rising has become historical rather than existential. What remains in the play is not the political content — it was never really about politics, and the rioters were wrong to read it that way — but the human scale. Ordinary people caught in the gears of large events. Grief that isn’t noble. Love that doesn’t make anyone a martyr. The same scenes that once registered as mockery now register as recognition: yes, that’s what it was like, that’s how it actually feels from inside history rather than from the bronze plaque afterward.
That’s intensification of communal sharing, not violation. The same play, different frame. The body goes still.
O’Casey, famously, refused to apologize. He thought the rioters were wrong about what his play was doing, and he was right. But there’s something worth noticing in their error: it was a kama muta error. They misread the play’s effect on their communal frame. They thought it was tearing something down. It was doing the opposite — placing the ordinary human beings of the Rising into a shared emotional space where audiences would feel their fates as their own. That’s what survived.
Theater is a technology for producing communal feeling. The Abbey existed to do this — to gather people in a room and intensify their sense of shared humanity. What O’Casey understood, and the rioters didn’t yet, is that mythologized heroism actually works against this mechanism. Heroes are abstract. Abstraction distances. The closer you get to the ordinary, the more available the communal feeling becomes — not just to one generation with a particular ideological stake, but to any audience with a human nervous system.
The rioters were protecting a mythological frame. The play was dismantling it to reach something underneath. A century of audiences, finding tears where the original crowd found outrage, is the proof of which one lasts.
Both the riot and the tears are physiological responses to confrontation with communal stakes. One was the feeling of violation; one is the feeling of recognition. The same machinery. The same theater. One frame that expired, and one that didn’t.
The body, in the end, knows the difference.
