perduring

How can beings of the moment grasp the perduring?

The perduring cause was peace � a cause he had first championed in his days at Columbia in the 1930s: peace among races, peace in Viet Nam, peace between the superpowers who were to decide the fate of billions of souls.

When you have compassed all weak I began, Diviner poet, and ah! diviner man; The man at feud with the perduring child In you before song's altar nobly reconciled; From the wise heavens I half shall smile to see How little a world, which owned you, needed me.
