  Arendt establishes the connection between action and plurality by means of an anthropological argument. In her view just as life is the condition that corresponds to the activity of labor and worldliness the condition that corresponds to the activity of work, so plurality is the condition that corresponds to action. She defines plurality as “the fact that men, not Man, live on the earth and inhabit the world,” and says that it is the condition of human action “because we are all the same, that is, human, in such a way that nobody is ever the same as anyone else who ever lived, lives, or will live ” (HC, 7–8). Plurality thus refers both to equality and distinction, to the fact that all human beings belong to the same species and are sufficiently alike to understand one another, but yet no two of them are ever interchangeable, since each of them is an individual endowed with a unique biography and perspective on the world.
