“Hope is the bedrock of this nation. The belief that our destiny will not be written for us, but by us, by all those men and women who are not content to settle for the world as it is, who have the courage to remake the world as it should be.”

2008, A World that Stands as One (July 2008)
Context: People of Berlin — and people of the world — the scale of our challenge is great. The road ahead will be long. But I come before you to say that we are heirs to a struggle for freedom. We are a people of improbable hope. With an eye toward the future, with resolve in our hearts, let us remember this history, and answer our destiny, and remake the world once again.

2004, Democratic National Convention speech (July 2004)
Context: In the end, that's what this election is about. Do we participate in a politics of cynicism or a politics of hope? I'm not talking about blind optimism here... No, I'm talking about something more substantial. It's the hope of slaves sitting around a fire singing freedom songs; the hope of immigrants setting out for distant shores; the hope of a young naval lieutenant bravely patrolling the Mekong Delta; the hope of a millworker's son who dares to defy the odds; the hope of a skinny kid with a funny name who believes that America has a place for him, too. Hope in the face of difficulty, hope in the face of uncertainty, the audacity of hope: In the end, that is God's greatest gift to us, the bedrock of this nation, a belief in things not seen, a belief that there are better days ahead.

Speech to the South Carolina Legislature, Columbia, SC (16 April 1947); Baruch said that the phrase "cold war" was suggested to him by H. B. Swope, editor of the New York World; the term had earlier been used by George Orwell (1945)
Context: Let us not be deceived — we are today in the midst of a cold war. Our enemies are to be found abroad and at home. Let us never forget this: Our unrest is the heart of their success. The peace of the world is the hope and the goal of our political system; it is the despair and defeat of those who stand against us.
