Report on Manufactures (1791)
Context: The expediency of encouraging manufactures in the United States, which was not long since deemed very questionable, appears at this time to be pretty generally admitted. (...) There still are, nevertheless, respectable patrons of opinions, unfriendly to the encouragement of manufactures. The following are, substantially, the arguments, by which these opinions are defended. (...) “In every country (say those who entertain them,) Agriculture is the most beneficial and productive object of human industry. (...) To endeavor by the extraordinary patronage of Government, to accelerate the growth of manufactures, is in fact, to endeavor, by force and art, to transfer the natural current of industry, from a more, to a less beneficial channel. Whatever has such a tendency must necessarily be unwise. Indeed it can hardly ever be wise in a government, to attempt to give a direction to the industry of its citizens. This under the quick-sighted guidance of private interest, will, if left to itself, infallibly find its own way to the most profitable employment; and it is by such employment, that the public prosperity will be most effectually promoted. To leave industry to itself, therefore, is, in almost every case, the soundest as well as the simplest policy.” This policy is not only recommended to the United States, by considerations which affect all nations, it is, in a manner, dictated to them by the imperious force of a very peculiar situation.

“In the long run an opinion often borrows credit from the forbearance of its patrons.”
"Essays in Criticism by Matthew Arnold," North American Review (July 1865).
Context: Grace Jones said this to me when I met her. I washed her feet, and I looked up at her and she said, "No matter what you do in your life, don’t you ever let anybody take your creative people away from you." And what my creative friends always remind me of is they say, "Only value the opinion of those that you respect. And anyone that you don’t respect, pay no mind to their opinion about you or anything else." And that’s how I live my life. If I worried about everything that everyone said, I would not be a good artist.
Variant: Relationship Principle 10
You can tell how much someone respects you by how much he respects your opinion. If he doesn't respect your opinion, he won't respect you.

“The less sure managers are of their opinions, the more vigorously they defend them.”
Source: 2000s, A little book of f-laws: 13 common sins of management, 2006, p. 8, bold text cited in: Gregory H. Watson (2010).
Context: The less sure managers are of their opinions, the more vigorously they defend them. Managers do not waste their time defending beliefs they hold strongly – they just assert them. Nor do they bother to refute what they strongly believe is false.
