“Planetary exploration satisfies our inclination for great enterprises and wanderings and quests that has been with us since our days as hunters and gatherers on the East African savannahs a million years ago. By chance—it is possible, I say, to imagine many skeins of historical causality in which this would not have transpired—in our age we are able to begin again.Exploring other worlds employs precisely the same qualities of daring, planning, cooperative enterprise, and valor that mark the finest in military tradition. Never mind the night launch of an Apollo spacecraft bound for another world. That makes the conclusion foregone. Witness mere F-14s taking off from adjacent flight decks, gracefully canting left and right, afterburners flaming, and there’s something that sweeps you away—or at least it does me. And no amount of knowledge of the potential abuses of carrier task forces can affect the depth of that feeling. It simply speaks to another part of me. It doesn’t want recriminations or politics. It just wants to fly.”

“We take off into the cosmos, ready for anything: for solitude, for hardship, for exhaustion, death. Modesty forbids us to say so, but there are times when we think pretty well of ourselves. And yet, if we examine it more closely, our enthusiasm turns out to be all a sham. We don't want to conquer the cosmos, we simply want to extend the boundaries of Earth to the frontiers of the cosmos. For us, such and such a planet is as arid as the Sahara, another as frozen as the North Pole, yet another as lush as the Amazon basin. We are humanitarian and chivalrous; we don't want to enslave other races, we simply want to bequeath them our values and take over their heritage in exchange. We think of ourselves as the Knights of the Holy Contact. This is another lie. We are only seeking Man. We have no need of other worlds. A single world, our own, suffices us; but we can't accept it for what it is. We are searching for an ideal image of our own world: we go in quest of a planet, a civilization superior to our own but developed on the basis of a prototype of our primeval past. At the same time, there is something inside us which we don't like to face up to, from which we try to protect ourselves, but which nevertheless remains, since we don't leave Earth in a state of primal innocence. We arrive here as we are in reality, and when the page is turned and that reality is revealed to us - that part of our reality which we would prefer to pass over in silence - then we don't like it anymore.”

“... he was taking a stab at greatness, that is, if greatness is simply another word for doing something different from what you were already doing — or maybe greatness is the thing we want to have so that other people will want to have us, or maybe greatness is merely the grail for our unhappy, striving selves, the thing we think we need, but don't and can't get anyway.”

“I profoundly believer, as Grammen's experience over twenty years has shown, that personal gains is not the only possible fuel for free enterprise. Social goals can replace greed as a powerful motivational force. Social-consciousness-driven enterprises can be formidable competitors for the greed-based enterprises. I believe that if we play our cards right, social-consciousness-driven enterprises can do very well in the marketplace.”

“The immature conscience is not its own master. It simply parrots the decisions of others. It does not make judgments of its own; it merely conforms to the judgments of others. That is not real freedom, and it makes true love impossible, for if we are to love truly and freely, we must be able to give something that is truly our own to another. If our heart does not belong to us, asks Merton, how can we give it to another?”

“This democracy we have is a precious thing. For all the arguments and all the doubts and all the cynicism that’s out there today, we should never forget that as Americans, we enjoy more freedoms and opportunities than citizens in any other nation on Earth. (Applause.) We are free to speak our mind and worship as we please. We are free to choose our leaders, and criticize them if they let us down. We have the chance to get an education, and work hard, and give our children a better life.None of this came easy. None of this was preordained. The men and women who sat in your chairs 10 years ago and 50 years ago and 100 years ago –- they made America possible through their toil and their endurance and their imagination and their faith. Their success, and America’s success, was never a given. And there is no guarantee that the graduates who will sit in these same seats 10 years from now, or 50 years from now, or 100 years from now, will enjoy the same freedoms and opportunities that you do. You, too, will have to strive. You, too, will have to push the boundaries of what seems possible. For the truth is, our nation’s destiny has never been certain.What is certain -– what has always been certain -– is the ability to shape that destiny. That is what makes us different. That is what sets us apart. That is what makes us Americans -– our ability at the end of the day to look past all of our differences and all of our disagreements and still forge a common future. That task is now in your hands, as is the answer to the question posed at this university half a century ago about whether a free society can still compete.”
