“We’re going to have to dig deep into our souls, confront our own self-doubt, and recognize that our destiny is in our hands – that our future is what we make of it. So let’s build the future we all know is possible. Let’s prove to our children that they really can reach for their dreams.”

Games for Actors and non-Actors (1992)
Context: In truth the Theatre of the Oppressed has no end, because everything which happens in it must extend into life…. The Theatre of the Oppressed is located precisely on the frontier between fiction and reality – and this border must be crossed. If the show starts in fiction, its objective is to become integrated into reality, into life. Now in 1992, when so many certainties have become so many doubts, when so many dreams have withered on exposure to sunlight, and so many hopes have become as many deceptions – now that we are living through times and situations of great perplexity, full of doubts and uncertainties, now more than ever I believe it is time for a theatre which, at its best, will ask the right questions at the right times. Let us be democratic and ask our audiences to tell us their desires, and let us show them alternatives. Let us hope that one day – please, not too far in the future – we’ll be able to convince or force our governments, our leaders, to do the same; to ask their audiences – us – what they should do, so as to make this world a place to live and be happy in – yes, it is possible – rather than just a vast market in which we sell our goods and our souls. Let’s hope. Let’s work for it!

2011, Address on interventions in Libya (March 2011)
Context: For generations, we have done the hard work of protecting our own people, as well as millions around the globe. We have done so because we know that our own future is safer, our own future is brighter, if more of mankind can live with the bright light of freedom and dignity. 
Tonight, let us give thanks for the Americans who are serving through these trying times, and the coalition that is carrying our effort forward. And let us look to the future with confidence and hope not only for our own country, but for all those yearning for freedom around the world.

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.
