"Let us reach for the world that ought to be – that spark of the divine that still stirs within each of our souls.
Somewhere today, in the here and now, in the world as it is, a soldier sees he's outgunned, but stands firm to keep the peace. Somewhere today, in this world, a young protestor awaits the brutality of her government, but has the courage to march on. Somewhere today, a mother facing punishing poverty still takes the time to teach her child, scrapes together what few coins she has to send that child to school – because she believes that a cruel world still has a place for that child's dreams.
Let us live by their example. We can acknowledge that oppression will always be with us, and still strive for justice. We can admit the intractability of deprivation and still strive for dignity. Clear-eyed, we can understand that there will be war, and still strive for peace.
We can do that – for that is the story of human progress; that's the hope of all the world; and at this moment of challenge, that must be our work here on Earth."
(Last part of Obama's 2009 Peace Nobel Prize speech)
