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.

The effect of one good-hearted person is incalculable.

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

Action had to be taken in response to the terrorist attacks on September 11, but I am very concerned about the current administration's rhetoric and apparent zeal to expand military action to other places. I'm afraid that terrorism is being used as an excuse, not only for possible military action in such places as Iraq, Iran, and the Philippines, but also for exorbitant increases in defense spending that have nothing to do with terrorism.

My country is a country of teachers. It is therefore a country of peace. We discuss our successes and failures in complete freedom. Because our country is a country of teachers, we closed the army camps, and our children go about with books under their arms, not with rifles on their shoulders. We believe in dialogue, in agreement, in reaching a consensus.

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

The problem with basing weapons sales on strategic interest is that these interests tend to shift over time, while weapons are durable goods that do not evaporate as quickly as some alliances do. Once supplied, they can't be taken back. That leads to situations such as the ones we have seen in Iraq, Somalia.
