“Traumatic events destroy the sustaining bonds between individual and community. Those who have survived learn that their sense of self, of worth, of humanity, depends upon a feeling of connection to others. The solidarity of a group provides the strongest protection against terror and despair, and the strongest antidote to traumatic experience. Trauma isolates; the group re-creates a sense of belonging. Trauma shames and stigmatizes; the group bears witness and affirms. Trauma degrades the victim; the group exalts her. Trauma dehumanizes the victim; the group restores her humanity.
Repeatedly in the testimony of survivors there comes a moment when a sense of connection is restored by another person’s unaffected display of generosity. Something in herself that the victim believes to be irretrievably destroyed — faith, decency, courage — is reawakened by an example of common altruism. Mirrored in the actions of others, the survivor recognizes and reclaims a lost part of herself. At that moment, the survivor begins to rejoin the human commonality.”
