The theory that can absorb the greatest number of facts, and persist in doing so, generation after generation, through all changes of opinion and detail, is the one that must rule all observation.
Adam Smith

I think there are many times when it would be most efficient to use nuclear weapons. However, the public opinion in this country and throughout the world throw up their hands in horror when you mention nuclear weapons, just because of the propaganda that's been fed to them.
Curtis Lemay

Atlas was permitted the opinion that he was at liberty, if he wished, to drop the Earth and creep away; but this opinion was all that he was permitted.
Franz Kafka

Stubborn and ardent clinging to one's opinion is the best proof of stupidity.
Michel de Montaigne

The corporate grip on opinion in the United States is one of the wonders of the Western world. No First World country has ever managed to eliminate so entirely from its media all objectivity - much less dissent.
Gore Vidal

Your representative owes you, not his industry only, but his judgment; and he betrays instead of serving you if he sacrifices it to your opinion.
Edmund Burke

Whenever a separation is made between liberty and justice, neither, in my opinion, is safe.
Edmund Burke

I don't always want my opinion known. What little privacy I have left I'd like to maintain.
Calvin Klein

If you are of the opinion that the contemplation of suicide is sufficient evidence of a poetic nature, do not forget that actions speak louder than words.
Fran Lebowitz

Contrary to popular opinion, the hustle is not a new dance step - it is an old business procedure.
Fran Lebowitz

Have a definite opinion.
William Safire

Do not imagine that what we have said of the insufficiency of our understanding and of its limited extent is an assertion founded only on the Bible: for philosophers likewise assert the same, and perfectly understand it,- without having regard to any religion or opinion.
Maimonides

The cleverest of all, in my opinion, is the man who calls himself a fool at least once a month.
Fyodor Dostoevsky

Truthiness is tearing apart our country, and I don't mean the argument over who came up with the word. I don't know whether it's a new thing, but it's certainly a current thing, in that it doesn't seem to matter what facts are. It used to be, everyone was entitled to their own opinion, but not their own facts. But that's not the case anymore. Facts matter not at all. Perception is everything.
Stephen Colbert

Everywhere I go, I'm asked if I think the universities stifle writers. My opinion is that they don't stifle enough of them. There's many a best seller that could have been prevented by a good teacher.
Flannery O'Connor

Between friends differences in taste or opinion are irritating in direct proportion to their triviality.
W. H. Auden

I have been ever of opinion that revolutions are not to be evaded.
Benjamin Disraeli

The first test of a truly great man is his humility. By humility I don't mean doubt of his powers or hesitation in speaking his opinion, but merely an understanding of the relationship of what he can say and what he can do.
John Ruskin

The fewer the facts, the stronger the opinion.
Arnold H. Glasow

Freedom of opinion can only exist when the government thinks itself secure.
Bertrand Russell
