These words have been much on my mind of late.

(abridged and condensed)

There are few earthly things more beautiful than a university -- wrote John Masefield in his tribute to English universities -- and his words are equally true today. He did not refer to towers or to campuses. He admired the splendid beauty of a university, because it was, he said, a place where those who hate ignorance may strive to know, where those who perceive truth may strive to make others see.

I have, therefore, chosen this time and place to discuss a topic on which ignorance too often abounds and the truth too rarely perceived -- and that is the most important topic on earth: peace.

What kind of peace do I mean and what kind of a peace do we seek? Not a Pax Americana enforced on the world by American weapons of war, not the peace of the grave or the security of the slave.

I am talking about genuine peace -- the kind of peace that makes life on earth worth living -- and the kind that enables men and nations to grow and to hope and build a better life for their children -- not merely peace for Americans but peace for all men and women -- not merely peace in our time but peace in all time.

Our problems are man-made. Therefore, they can be solved by man.

So let us persevere. Peace need not be impracticable -- and war need not be inevitable. By defining our goal more clearly -- by making it seem more manageable and less remote -- we can help all people to see it, to draw hope from it and to move irresistibly towards it.

So let us not be blind to our differences, but let us also direct attention to our common interests and the means by which those differences can be resolved. And if we cannot end now our differences, at least we can help make the world safe for diversity.

For, in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's futures. And we are all mortal.

- President John F. Kennedy, at American University, 10 June 1963
