“A love of tradition has never weakened a nation, indeed it has strengthened nations in their hour of peril; but the new view must come, the world must roll forward … Let us have no fear of the future.”

1960s, The Quest for Peace and Justice (1964)
Context: The time has come for an all-out world war against poverty. The rich nations must use their vast resources of wealth to develop the underdeveloped, school the unschooled, and feed the unfed. Ultimately a great nation is a compassionate nation. No individual or nation can be great if it does not have a concern for "the least of these". Deeply etched in the fiber of our religious tradition is the conviction that men are made in the image of God and that they are souls of infinite metaphysical value, the heirs of a legacy of dignity and worth. If we feel this as a profound moral fact, we cannot be content to see men hungry, to see men victimized with starvation and ill health when we have the means to help them. The wealthy nations must go all out to bridge the gulf between the rich minority and the poor majority.

1990s, Inaugural celebration address (1994)
Context: We are both humbled and elevated by the honour and privilege that you, the people of South Africa, have bestowed on us, as the first President of a united, democratic, non-racial and non-sexist government.
We understand it still that there is no easy road to freedom
We know it well that none of us acting alone can achieve success.
We must therefore act together as a united people, for national reconciliation, for nation building, for the birth of a new world.
Let there be justice for all.
Let there be peace for all.
