I am not a pacifist, however I do believe that the U.S. tends to resort to force too quickly. I am not referring only to the current administration; the same thing happened in the Balkans, and on other occasions.

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

The effect of one good-hearted person is incalculable.

Hope is the strongest driving force for a people. Hope which brings about change, which produces new realities, is what opens man's road to freedom. Once hope has taken hold, courage must unite with wisdom. That is the only way of avoiding violence, the only way of maintaining the calm one needs to respond peacefully to offenses.

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.

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

The most deadly disease truly is the failure of the heart.
