“Whether Protection is a universal poison, or whether it may be conceived to operate as food in cases where it is granted for a few years in order to shelter the first investments in a new industry, I do not now inquire. We at least have never seen or known it in that mitigated form. With us it has sheltered nothing but the most selfish instincts of class against the just demands of the public welfare. These it has supplied with strongholds, from whose portals our producers have too generally marched forth in the day of need, armed from head to foot with power and influence largely gotten at the expense of the community, to do battle with a perverted prowess, against nature, liberty, and justice.”

Seton Hall Address (2002)
Context: They killed in the name of God. But they are not the first. This began in pre-history; the tragedy is that it persists today.
Some would characterize the events of 9-11 as a clash of civilizations, and a conflict of religions. And to many it seems a simple and satisfying explanation.
But others would suggest, correctly in my view, that such an interpretation is both wrong-headed and dangerous. They recognize a civil war within Islam itself, as contending factions compete for power. They would argue that we must influence the struggle where we can, by supporting greater attention to the secular structures in the Islamic world, and by encouraging our own American Islamic community to speak out in support of America’s democratic values.
Ultimately, your generation will have the decisive voice. You will determine whether rage or reason guides the United States in the struggle to come. You will choose whether we are known for revenge or compassion. You will choose whether we, too, will kill in the name of God, or whether in His Name, we can find a higher civilization and a better means of settling our differences.
And this is not a new choice, not for your generation — it is a choice that many others have faced throughout history. Only now, we can hope that with your help and engagement we can find a new answer.

1962, Rice University speech
Context: The growth of our science and education will be enriched by new knowledge of our universe and environment, by new techniques of learning and mapping and observation, by new tools and computers for industry, medicine, the home as well as the school. Technical institutions, such as Rice, will reap the harvest of these gains. And finally, the space effort itself, while still in its infancy, has already created a great number of new companies, and tens of thousands of new jobs. Space and related industries are generating new demands in investment and skilled personnel, and this city and this state, and this region, will share greatly in this growth.
