“Ours, too, should be a declaration of difference and distance—"We hold these truths to be self-evident; that all men are created unequal." In the wake of the old world, this will be our proposition.”

Context: South Carolina cites, loosely, but with substantial accuracy, some of the language of the original Declaration. That Declaration does say that it is the right of the people to abolish any form of government that becomes destructive of the ends for which it was established. But South Carolina does not repeat the preceding language in the earlier document: 'We hold these truths to be self-evident, that all men are created equal'.

That is the true genius of America—a faith in simple dreams, an insistence on small miracles.

Context: America is already great. America is already strong. And I promise you, our strength, our greatness, does not depend on Donald Trump. In fact, it doesn’t depend on any one person. And that, in the end, may be the biggest difference in this election — the meaning of our democracy.
Ronald Reagan called America “a shining city on a hill.” Donald Trump calls it “a divided crime scene” that only he can fix. It doesn’t matter to him that illegal immigration and the crime rate are as low as they’ve been in decades — (applause) — because he’s not actually offering any real solutions to those issues. He’s just offering slogans, and he’s offering fear. He’s betting that if he scares enough people, he might score just enough votes to win this election.
And that's another bet that Donald Trump will lose. And the reason he'll lose it is because he’s selling the American people short. We're not a fragile people. We're not a frightful people. Our power doesn’t come from some self-declared savior promising that he alone can restore order as long as we do things his way. We don’t look to be ruled. Our power comes from those immortal declarations first put to paper right here in Philadelphia all those years ago: We hold these truths to be self-evident, that all men are created equal; that We the People, can form a more perfect union.
That's who we are. That’s our birthright — the capacity to shape our own destiny.

1850s, Speech at Chicago (1858)
Context: There is something else connected with it. We have besides these men — descended by blood from our ancestors — among us perhaps half our people who are not descendants at all of these men, they are men who have come from Europe — German, Irish, French and Scandinavian — men that have come from Europe themselves, or whose ancestors have come hither and settled here, finding themselves our equals in all things. If they look back through this history to trace their connection with those days by blood, they find they have none, they cannot carry themselves back into that glorious epoch and make themselves feel that they are part of us, but when they look through that old Declaration of Independence they find that those old men say that 'We hold these truths to be self-evident, that all men are created equal,' and then they feel that that moral sentiment taught in that day evidences their relation to those men, that it is the father of all moral principle in them, and that they have a right to claim it as though they were blood of the blood, and flesh of the flesh of the men who wrote that Declaration, and so they are. That is the electric cord in that Declaration that links the hearts of patriotic and liberty-loving men together, that will link those patriotic hearts as long as the love of freedom exists in the minds of men throughout the world.

BBC News, ' Scottish independence: One million Scots urged to sign 'yes' declaration http://www.bbc.co.uk/news/uk-scotland-scotland-politics-18162832' (25 May 2012).
Context: We unite behind a declaration of self-evident truth. The people who live in Scotland are best placed to make the decisions that affect Scotland. We want a Scotland that's greener, that's fairer and more prosperous. We realise that the power of an independent Scotland is necessary to achieve these great ends... By the time we enter the referendum campaign in autumn 2014, our intention is to have one million Scots who have signed the independence for Scotland declaration. Friends, if we achieve that, then we shall win an independent Scotland.
