  The second feature stressed by Arendt has to do with the spatial quality of public life, with the fact that political activities are located in a public space where citizens are able to meet one another, exchange their opinions and debate their differences, and search for some collective solution to their problems. Politics, for Arendt, is a matter of people sharing a common world and a common space of appearance so that public concerns can emerge and be articulated from different perspectives. In her view, it is not enough to have a collection of private individuals voting separately and anonymously according to their private opinions. Rather, these individuals must be able to see and talk to one another in public, to meet in a public-political space, so that their differences as well as their commonalities can emerge and become the subject of democratic debate.
