“The Democrats had long labeled the impeachment debate a distraction from the urgent business of a great nation. But the Republicans argued that the pursuit of justice is the business of a great nation. In winning this point, they caught the falling flag, producing a triumph for the rule of law, a reassertion of the belief that no man is above it, and a rebuke for an arrogance that had grown imperial.”

Connections (1979), 1 - The Trigger Effect
Context: An invention acts rather like a trigger, because, once it's there, it changes the way things are, and that change stimulates the production of another invention, which in turn, causes change, and so on. Why those inventions happened, between 6,000 years ago and now, where they happened and when they happened, is a fascinating blend of accident, genius, craftsmanship, geography, religion, war, money, ambition... Above all, at some point, everybody is involved in the business of change, not just the so-called "great men." Given what they knew at the time, and a moderate amount of what's up here [pointing to head], I hope to show you that you or I could have done just what they did, or come close to it, because at no time did an invention come out of thin air into somebody's head, [snaps fingers] like that. You just had to put a number of bits and pieces, that were already there, together in the right way.

All for Australia (1984)

1970s, First Presidential address (1974)
Context: My fellow Americans, our long national nightmare is over.
Our Constitution works; our great Republic is a government of laws and not of men. Here the people rule. But there is a higher Power, by whatever name we honor Him, who ordains not only righteousness but love, not only justice but mercy.
As we bind up the internal wounds of Watergate, more painful and more poisonous than those of foreign wars, let us restore the golden rule to our political process, and let brotherly love purge our hearts of suspicion and of hate.

2013, "Let Freedom Ring" Ceremony (August 2013)
Context: The test was not, and never has been, whether the doors of opportunity are cracked a bit wider for a few. It was whether our economic system provides a fair shot for the many -- for the black custodian and the white steelworker, the immigrant dishwasher and the Native American veteran. To win that battle, to answer that call -- this remains our great unfinished business.
