Report on Manufactures (1791)
Context: To cherish and stimulate the activity of the human mind, by multiplying the objects of enterprise, is not among the least considerable of the expedients, by which the wealth of a nation may be promoted. Even things in themselves not positively advantageous, sometimes become so, by their tendency to provoke exertion. Every new scene, which is opened to the busy nature of man to rouse and exert itself, is the addition of a new energy to the general stock of effort.

1900s, The Moral Equivalent of War (1906)
Context: The war-party is assuredly right in affirming and reaffirming that the martial virtues, although originally gained by the race through war, are absolute and permanent human goods. Patriotic pride and ambition in their military form are, after all, only specifications of a more general competitive passion. They are its first form, but that is no reason for supposing them to be its last form. Men are now proud of belonging to a conquering nation, and without a murmur they lay down their persons and their wealth, if by so doing they may fend off subjection. But who can be sure that other aspects of one's country may not, with time and education and suggestion enough, come to be regarded with similarly effective feelings of pride and shame? Why should men not some day feel that is it worth a blood-tax to belong to a collectivity superior in any respect? Why should they not blush with indignant shame if the community that owns them is vile in any way whatsoever? Individuals, daily more numerous, now feel this civic passion. It is only a question of blowing on the spark until the whole population gets incandescent, and on the ruins of the old morals of military honor, a stable system of morals of civic honor builds itself up. What the whole community comes to believe in grasps the individual as in a vise. The war-function has grasped us so far; but the constructive interests may some day seem no less imperative, and impose on the individual a hardly lighter burden.

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.
