CONCEPT
The Public Realm (Arendt)
Arendt's space of appearance — the common world where actors encounter one another through deed and word, and where action becomes possible because others are present to witness, judge, and respond.
The public realm, for Arendt, is the space constituted by the encounter of distinct persons acting and speaking together. It has two features: it is a space of appearance where each actor reveals who she is to others, and it is a common world — a shared durable reality of institutions, practices, and artifacts that persists across generations. The public realm is not a geographical location but a condition: wherever plural persons gather to act and speak, a public realm comes into being; when they disperse or are silenced, it dissolves. Arendt's diagnosis was that modern conditions — mass society, consumerism, privatization — had been hollowing out the public realm for a century, and the AI transition threatens to complete the erosion by moving creative and productive activity into private dialogue with a machine.
