We must first bring others to see their own true interests better than they do today. - John F. Kennedy

You have responsibilities, in short, to use your talents for the benefit of the society which helped develop those talents. You must decide, as Goethe put it, whether you will be an anvil or a hammer, whether you will give to the world in which you were reared and educated the broadest possible benefits of that education. Of the many special obligations incumbent upon an educated citizen, I would cite three as outstanding: your obligation to the pursuit of learning, your obligation to serve the public, your obligation to uphold the law.

Commander Shepard has pointed out from the time that this flight began and from the time this flight was a success, that this was a common effort in which a good many men were involved. I think it does credit to him that he is associated with such a distinguished group of Americans whom we are all glad to honor today, his companions in the flight into outer space, so I think we want to give them all a hand. ... I also want to take cognizance of the fact that this flight was made out in the open with all the possibilities of failure, which would have been damaging to our country's prestige. Because great risks were taken in that regard, it seems to me that we have some right to claim that this open society of ours which risked much, gained much. ... This is a civilian award for a great civilian accomplishment, and therefore I want to again express my congratulations to Alan Shepard. We are very proud of him, and I speak on behalf of the Vice President, who is Chairman of our Space Council and who bears great responsibilities in this field, and the Members of the House and Senate Space Committee who are with us today.

With all of the history of war, and the human race's history unfortunately has been a good deal more war than peace, with nuclear weapons distributed all through the world, and available, and the strong reluctance of any people to accept defeat, I see the possibility in the 1970's of the President of the United States having to face a world in which 15 or 20 or 25 nations may have these weapons."
