“Peaceful coexistence cannot be limited to the powerful countries if we want to ensure world peace. Peaceful coexistence must be exercised among all states, regardless of size, regardless of the previous historical relations that linked them, and regardless of the problems that may arise among some of them at a given moment.”

Address to the United Nations (1964)

Context: The strategy of peaceful coexistence and collaboration must be deepened in every way. Scientific methods and principles of international policy will have to be worked out, based on scientific prediction of the immediate and more distant consequences.
The initiative must be seized in working out a broad program of struggle against hunger.
A law on press and information must be drafted, widely discussed, and adopted, with the aim not only of ending irresponsible and irrational censorship, but also of encouraging self-study in our society, fearless discussion, and the search for truth. The law must provide for the material resources of freedom of thought.
All anti-constitutional laws and decrees violating human rights must be abrogated.

Context: In order for the world to become peaceful, people must become more peaceful. Among mature people war would not be a problem — it would be impossible. In their immaturity people want, at the same time, peace and the things which make war. However, people can mature just as children grow up. Yes, our institutions and our leaders reflect our immaturity, but as we mature we will elect better leaders and set up better institutions. It always comes back to the thing so many of us wish to avoid: working to improve ourselves.

Address at the opening of the Exhibit on the World's Religions at Santa Clara University (31 March 2005) note: Elaborations and extensions of this declaration occur in Küng's later writings, including: There will be no peace among the nations without peace among the religions. There will be no peace among the religions without dialogue among the religions. There will be no dialogue among the religions without global ethical standards. There will therefore be no survival of this globe without a global ethic.
