“The basis of all true cosmic horror is violation of the order of nature, and the profoundest violations are always the least concrete and describable.”

Speech (3 January 1834), quoted in Lafayette in Two Worlds: Public Cultures and Personal Identities in an Age of Revolutions (1999), p. 256
Context: True republicanism is the sovereignty of the people. There are natural and imprescriptible rights which an entire nation has no right to violate, just as national sovereignty is above the secondary agreements of the government.

1830s, The Lyceum Address (1838)
Context: Let every American, every lover of liberty, every well-wisher to his posterity swear by the blood of the Revolution never to violate in the least particular the laws of the country, and never to tolerate their violation by others. As the patriots of seventy-six did to the support of the Declaration of Independence, so to the support of the Constitution and laws let every American pledge his life, his property, and his sacred honor — let every man remember that to violate the law is to trample on the blood of his father, and to tear the charter of his own and his children's liberty. Let reverence for the laws be breathed by every American mother to the lisping babe that prattles on her lap; let it be taught in schools, in seminaries, and in colleges; let it be written in primers, spelling-books, and in almanacs; let it be preached from the pulpit, proclaimed in legislative halls, and enforced in courts of justice. And, in short, let it become the political religion of the nation; and let the old and the young, the rich and the poor, the grave and the gay of all sexes and tongues and colors and conditions, sacrifice unceasingly upon its altars. While ever a state of feeling such as this shall universally or even very generally prevail throughout the nation, vain will be every effort, and fruitless every attempt, to subvert our national freedom.

Zen and the Art of Motorcycle Maintenance (1974), Afterword (1984)
Context: Uncle Tom's Cabin was no literary masterpiece but it was a culture-bearing book. It came at a time when the entire culture was about to reject slavery. People seized upon it as a portrayal of their own new values and it became an overwhelming success.
The success of Zen and the Art of Motorcycle Maintenance seems the result of this culture-bearing phenomenon. The involuntary shock treatment described here is against the law today. It is a violation of human liberty. The culture has changed.
