Philanthropy, charity, giving voluntarily and freely... call it what you like, but it is truly a jewel of an American tradition.

I ask particularly that those of you who are now in school will prepare yourselves to bear the burden of leadership over the next 40 years here in the United States, and make sure that the United States - which I believe almost alone has maintained watch and ward for freedom - that the United States meet its responsibility. That is a wonderful challenge for us as a people.

Above all, we are coming to understand that the arts incarnate the creativity of a free people.

We must live our lives in such a way that our children, and their children after them, will form a natural and lasting commitment to the vigorous life. Only in this way can we be assured that the spirit and strength of America will be constantly replenished.

So let us begin anew -- remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. Let us never negotiate out of fear, but let us never fear to negotiate. Let both sides explore what problems unite us instead of belaboring those problems which divide us.

There are many people in the world who really don't understand, or say they don't, what is the great issue between the free world and the Communist world. Let them come to Berlin. There are some who say that communism is the wave of the future. Let them come to Berlin. And there are some who say in Europe and elsewhere we can work with the Communists. Let them come to Berlin. And there are even a few who say that it is true that communism is an evil system, but it permits us to make economic progress. Lass' sie nach Berlin kommen. Let them come to Berlin.

To each of us is entrusted the heavy responsibility of guiding the affairs of a democratic nation founded on Christian ideals.
