  The space of appearance must be continually recreated by action; its existence is secured whenever actors gather together for the purpose of discussing and deliberating about matters of public concern, and it disappears the moment these activities cease. It is always a potential space that finds its actualization in the actions and speeches of individuals who have come together to undertake some common project. It may arise suddenly, as in the case of revolutions, or it may develop slowly out of the efforts to change some specific piece of legislation or policy. Historically, it has been recreated whenever public spaces of action and deliberation have been set up, from town hall meetings to workers’ councils, from demonstrations and sit-ins to struggles for justice and equal rights.
