And third, medical space research may lead to new safeguards against hazards common to many environments. Specifically, our astronauts will need fund… - John F. Kennedy

I urge all of you today, especially those who are students, to act, to enter the lists of public service and rightly win or lose the prize. For we can have only one form of aristocracy in this country, as Jefferson wrote long ago in rejecting John Adams' suggestion of an artificial aristocracy of wealth and birth. It is, he wrote, the natural aristocracy of character and talent, and the best form of government, he added, was that which selected these men for positions of responsibility.

This day devoted to the memory of Robert Frost offers an opportunity for reflection which is prized by politicians as well as by others, and even by poets, for Robert Frost was one of the granite figures of our time in America. He was supremely two things: an artist and an American. A nation reveals itself not only by the men it produces but also by the men it honors, the men it remembers. In America, our heroes have customarily run to men of large accomplishments. But today this college and country honors a man whose contribution was not to our size but to our spirit, not to our political beliefs but to our insight, not to our self-esteem, but to our self- comprehension. In honoring Robert Frost, we therefore can pay honor to the deepest sources of our national strength. That strength takes many forms, and the most obvious forms are not always the most significant. The men who create power make an indispensable contribution to the Nation's greatness, but the men who question power make a contribution just as indispensable, especially when that questioning is disinterested, for they determine whether we use power or power uses us.

Much time has passed since the first colonists came to rocky shores and dark forests of an unknown continent, much time since President Washington led a young people into the experience of nationhood, much time since President Lincoln saw the American nation through the ordeal of fraternal war — and in these years our population, our plenty and our power have all grown apace. Today we are a nation of nearly two hundred million souls, stretching from coast to coast, on into the Pacific and north toward the Arctic, a nation enjoying the fruits of an ever-expanding agriculture and industry and achieving standards of living unknown in previous history. We give our humble thanks for this. Yet, as our power has grown, so has our peril. Today we give our thanks, most of all, for the ideals of honor and faith we inherit from our forefathers — for the decency of purpose, steadfastness of resolve and strength of will, for the courage and the humility, which they possessed and which we must seek every day to emulate. As we express our gratitude, we must never forget that the highest appreciation is not to utter words but to live by them. Let us therefore proclaim our gratitude to Providence for manifold blessings — let us be humbly thankful for inherited ideals — and let us resolve to share those blessings and those ideals with our fellow human beings throughout the world.
