“The questions we face today -- how to promote equality and justice; how to uphold freedom and human rights; how to end conflict and sectarian war -- these things do not have easy answers. But there were no easy answers in front of that child born in World War I. Nelson Mandela reminds us that it always seems impossible until it is done. South Africa shows that is true. South Africa shows we can change, that we can choose a world defined not by our differences, but by our common hopes. We can choose a world defined not by conflict, but by peace and justice and opportunity.”

2009, A World without Nuclear Weapons (April 2009)
Context: Now, I know that there are some who will question whether we can act on such a broad agenda. There are those who doubt whether true international cooperation is possible, given inevitable differences among nations. And there are those who hear talk of a world without nuclear weapons and doubt whether it's worth setting a goal that seems impossible to achieve.
But make no mistake: We know where that road leads. When nations and peoples allow themselves to be defined by their differences, the gulf between them widens. When we fail to pursue peace, then it stays forever beyond our grasp. We know the path when we choose fear over hope. To denounce or shrug off a call for cooperation is an easy but also a cowardly thing to do. That's how wars begin. That's where human progress ends.

As quoted in Voices of Liberation: Albert Lutuli (1993).
Resist apartheid! (1954)
Context: The laws and policies of white South Africa are no doubt inimical to this development. And so I call upon our people in all walks of life ministers of the Gospel of Christ, who died to save human dignity, teachers, professional men, business men; farmers and workers to rally round the congress at this hour to make our voice heard. We may be voteless, but we are not necessarily voiceless; it is our determination more than ever before in the life of our congress, to have our voice not only heard but heeded too. Through gatherings like this in all centres, large and small, we mean to mobilize our people to speak with this one voice and say to white South Africa: We have no designs to elbow anyone out of South Africa, but equally we have no intention whatsoever of abandoning our divine right, of ourselves determining our destiny according to the holy and perfect plan of our Creator. Apartheid can never be such a plan.

1990s, Victory speech (1994)
Context: The calm and tolerant atmosphere that prevailed during the elections depicts the type of South Africa we can build. It set the tone for the future. We might have our differences, but we are one people with a common destiny in our rich variety of culture, race and tradition.
People have voted for the party of their choice and we respect that. This is democracy.
I hold out a hand of friendship to the leaders of all parties and their members, and ask all of them to join us in working together to tackle the problems we face as a nation. An ANC government will serve all the people of South Africa, not just ANC members.
