Hannah Arendt: Responsabilidad colectiva

We call compassion what I feel when somebody else suffers; and this feeling is authentic only so long as I realize that it is, after all, not I but somebody else who suffers. But it is true, I think, that "solidarity is a necessary condition" for such emotions; which, in our case of collective guilt feelings would mean that the cry "We are all guilty" is actually a declaration of solidarity with the wrongdoers.

Never mind who suffers it [wrong]; your duty is to prevent it.

(Hannah Arendt, "Collective Responsibility")
