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.

It's clear to me that many weapons sales are very short-sighted. The U.S. and other arms-producing countries sell weapons for a variety of reasons, but most sales involve strategic interest or profit motivation, or both.

I am constantly challenged by pessimists who insist that military solutions are the only way to go. This was true in the 1980s, and it is true today. You should know that I do not consider myself a pacifist; there are times, in my view, when military action may be necessary.

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.

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 is a never-ending process, the work of many decisions by many people in many countries. It is an attitude, a way of life, a way of solving problems and resolving conflicts. It cannot be forced on the smallest nation or enforced by the largest. It cannot ignore our differences or overlook our common interests. It requires us to work and live together.
