What passes for identity in America is a series of myths about one's heroic ancestors.
An identity would seem to be arrived at by the way in which the person faces and uses his experience.
An identity is questioned only when it is menaced, as when the mighty begin to fall, or when the wretched begin to rise, or when the stranger enters the gates, never, thereafter, to be a stranger.
To ask questions of the universe, and then learn to live with those questions, is the way he achieves his own identity.
