The effect of one good-hearted person is incalculable.

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

While the armed forces have intervened in the political affairs of every other Central American country over the past fifty years, with disastrous results, in Costa Rica we have peacefully transferred power from one administration to the next every four years.

War, and the preparation for war, are the two greatest obstacles to human progress, fostering a vicious cycle of arms buildups, violence and poverty.

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.

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.

For ages the world has been living by the stupidity of an old Roman adage that says if you want peace, prepare for war. As if anything said in ancient times must be wise, people have used this phrase to justify some of the most unjustifiable arms build-ups, which, far from creating peace, has only become a self-fulfilling prophecy.
