I would like to see the U.S. fighting another war, perhaps in addition to that against terror: a war on poverty, illiteracy, disease and environmental degradation. It is certainly within the power of your country to act on all of these fronts, but, unfortunately, your leaders have become obsessed with a single issue.

The effect of one good-hearted person is incalculable.

Peace is a never ending process... It cannot ignore our differences or overlook our common interests. It requires us to work and live together.

The existence of nuclear weapons presents a clear and present danger to life on Earth.

Peace is not a dream; it is hard work, and there is nothing naive, glamorous or simplistic about it.

Peace consists, very largely, in the fact of desiring it with all one's soul. The inhabitants of my small country, Costa Rica, have realized those words by Erasmus. Mine is an unarmed people, whose children have never seen a fighter or a tank or a warship.

It is essential that justice be done, and it is equally vital that justice not be confused with revenge, for the two are wholly different.
