“The parallel between 1787 and 1948 is naturally not exact. Even if it were, 1787 would have no authority over 1948. Each age must make or keep its own government and determine its own future.”

Context: Now, make no mistake: History is on the side of these brave Africans, not with those who use coups or change constitutions to stay in power. Africa doesn't need strongmen; it needs strong institutions. Now, America will not seek to impose any system of government on any other nation. The essential truth of democracy is that each nation determines its own destiny.

On claims of waterboarding as being impedimental in as quoted in "John McCain to Bush apologists: Stop lying about Bin Laden and torture" by Greg Sar in The Washington Post (12 May 2011) http://www.washingtonpost.com/blogs/plum-line/post/john-mccain-to-bush-apologists-stop-lying-about-bin-laden-and-torture/2011/03/03/AF10AnzG_blog.html - YouTube video of McCaine's speech http://www.youtube.com/watch?v=3I94Yb4KUic

Context: We did not learn Abu Ahmed’s real name or alias as a result of waterboarding or any "enhanced interrogation technique" used on a detainee in U. S. custody. None of the three detainees who were waterboarded provided Abu Ahmed’s real name, his whereabouts, or an accurate description of his role in Al-Qaeda. … In fact, not only did the use of "enhanced interrogation techniques" on Khalid Sheikh Mohammed not provide us with key leads on bin Laden’s courier, Abu Ahmed; it actually produced false and misleading information. Khalid Sheikh Mohammed specifically told his interrogators that Abu Ahmed had moved to Peshawar, got married, and ceased his role as an Al-Qaeda facilitator — which was not true, as we now know. … It was not torture or cruel, inhuman, and degrading treatment of detainees that got us the major leads that ultimately enabled our intelligence community to find Osama bin Laden. … we are again engaged in this important debate, with much at stake for America’s security and reputation. Each side should make its own case, but do so without making up its own facts.

1860s, Fourth of July Address to Congress (1861)
Context: And this issue embraces more than the fate of these United States. It presents to the whole family of man the question whether a constitutional republic, or democracy — a government of the people by the same people — can or can not maintain its territorial integrity against its own domestic foes. It presents the question whether discontented individuals, too few in numbers to control administration according to organic law in any case, can always, upon the pretenses made in this case, or on any other pretenses, or arbitrarily without any pretense, break up their government, and thus practically put an end to free government upon the earth. It forces us to ask, Is there in all republics this inherent and fatal weakness? Must a government of necessity be too strong for the liberties of its own people, or too weak to maintain its own existence?

Section III, "Of Civil Liberty"
Essay on the First Principles of Government, 2nd Edition (1771)

Obergefell v. Hodges http://www.supremecourt.gov/opinions/14pdf/14-556_3204.pdf (26 June 2015).
2010s
Context: The Court's decision today is at odds not only with the constitution, but with the principles upon which our Nation was built. Since well before 1787, liberty has been understood as freedom from government action, not entitlement to government benefits. The framers created our constitution to preserve that understanding of liberty. Yet the majority invokes our Constitution in the name of a 'liberty' that the framers would not have recognized, to the detriment of the liberty they sought to protect. Along the way, it rejects the idea—captured in our Declaration of Independence—that human dignity is innate and suggests instead that it comes from the Government. This distortion of our Constitution not only ignores the text, it inverts the relationship between the individual and the state in our Republic. I cannot agree with it.
