“But peace does not rest in charters and covenants alone. It lies in the hearts and minds of all people. And if it is cast out there, then no act, no pact, no treaty, no organization can hope to preserve it without the support and the wholehearted commitment of all people. So let us not rest all our hopes on parchment and on paper; let us strive to build peace, a desire for peace, a willingness to work for peace, in the hearts and minds of all our people.”

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.

His Independence Day Message, quoted on Asian Tribute (February 4, 2016), "Let us pledge to consolidate on peace and freedom achieved and builds this future for our land and people – President Maithripala Srisena" http://www.asiantribune.com/node/88511
Context: As we commemorate independence, let us dedicate ourselves to provide a truly ethical, virtuous, wise and equitable service to all. Let us pledge to consolidate on peace and freedom achieved and builds this future for our land and people. On this day, as we celebrate the 68th anniversary of our Independence, we are proud of the progress made towards safeguarding the freedom, sovereignty, territorial integrity of the Nation and strengthening national reconciliation and economic and political rights of all our citizens. This occasion is of special significance because we commemorate the dawn of freedom, at a time coinciding with the taking of clear and resolute steps to firmly establish democracy and good governance, the Rule of Law, and a truly meaningful parliamentary system; to establish a long lasting and stable structure of good governance, in keeping with the mandate given by the people one year ago. We are resolved to continue on this path to create a socio political environment for all citizens to live securely without fear. After achieving these, we have commenced a new drive for development, of which much remains to be done. It is our belief that the strength of our freedom largely depends on developing indigenous skills and knowledge, while zealously guarding the rich cultural and social heritage of our past and move ahead to the victories of the future. As we celebrate the gaining of Independence, today, we recognize our bounden duty to given all honor and respect to the members of the Security Forces who made great sacrifices to protect our sovereignty and territorial integrity in the battle against terrorism. Our foreign policy of middle path, with a commitment to justice and humanity, has won us friends in the international community who are ready to help us in our march towards prosperity. As we commemorate independence, let us dedicate ourselves to provide a truly ethical, virtuous, wise and equitable service to all. Let us pledge to consolidate on peace and freedom achieved and build this future for our land and people

1990s, Inaugural celebration address (1994)
Context: We succeeded to take our last steps to freedom in conditions of relative peace. We commit ourselves to the construction of a complete, just and lasting peace.
We have triumphed in the effort to implant hope in the breasts of the millions of our people. We enter into a covenant that we shall build the society in which all South Africans, both black and white, will be able to walk tall, without any fear in their hearts, assured of their inalienable right to human dignity — a rainbow nation at peace with itself and the world.

Variant: Total security has never been available to anyone. To expect it is unrealistic; to imagine that it can exist is to invite disaster. I believe the most important aim for humanity at present is to avoid war, dictatorship, and their awful consequences.
Better a Shield Than A Sword : Perspectives On Defense And Technology (1987), p. 241
Context: The preservation of peace and the improvement of the lot of all people require us to have faith in the rationality of humans. If we have this faith and if we pursue understanding, we have not the promise but at least the possibility of success. We should not be misled by promises. Humanity in all its history has repeatedly escaped disaster by a hair's breadth. Total security has never been available to anyone. To expect it is unrealistic; to imagine that it can exist is to invite disaster. What we do have in our technological capacities is an opportunity to use our inventiveness, our creativity, our wisdom and our understanding of our fellow beings to create a future world that is a little better than the one in which we live today.

As quoted in Global History, Volume Two : The Industrial Revolution to the Age of Globalization (2008) by Jerry Weiner, Mark Willner, George A. Hero and Bonnie-Anne Briggs, p. 175
Context: Mexicans: let us now pledge all our efforts to obtain and consolidate the benefits of peace. Under its auspices, the protection of the laws and of the authorities will be sufficient for all the inhabitants of the Republic. May the people and the government respect the rights of all. Between individuals, as between nations, peace means respect for the rights of others.

Context: We are disposed, somewhat by culture and somewhat by nature, to solve our problems by violence, and even to enjoy doing so. And yet by now all of us must at least have suspected that our right to live, to be free, and to be at peace is not guaranteed by any act of violence. It can be guaranteed only by our willingness that all other persons should live, be free, and be at peace — and by our willingness to use or give our own lives to make that possible.
