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

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.

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

The effect of one good-hearted person is incalculable.

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.

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.

I cannot accept that to be realistic means to tolerate misery, violence and hate. I do not believe that the hungry man should be treated as subversive for expressing his suffering. I shall never accept that the law can be used to justify tragedy, to keep things as they are, to make us abandon our ideas of a different world. Law is the path of liberty, and must as such open the way to progress for everyone.
