“Their coarseness is the sinew of some kind of brute confidence which is the reason England is home to every shade of political exile. They don't give asylum out of respect for asylum-seekers, but out of respect for themselves. They invented personal liberty, and they know it, and they did it without having any theories about it. They value liberty because it's liberty.”

The American Credo: A Contribution toward the Interpretation of the National Mind (1920)
1920s
Context: The American of today, in fact, probably enjoys less personal liberty than any other man of Christendom, and even his political liberty is fast succumbing to the new dogma that certain theories of government are virtuous and lawful, and others abhorrent and felonious. Laws limiting the radius of his free activity multiply year by year: It is now practically impossible for him to exhibit anything describable as genuine individuality, either in action or in thought, without running afoul of some harsh and unintelligible penalty. It would surprise no impartial observer if the motto “In God we trust” were one day expunged from the coins of the republic by the Junkers at Washington, and the far more appropriate word, “verboten,” substituted. Nor would it astound any save the most romantic if, at the same time, the goddess of liberty were taken off the silver dollars to make room for a bas-relief of a policeman in a spiked helmet. Moreover, this gradual (and, of late, rapidly progressive) decay of freedom goes almost without challenge; the American has grown so accustomed to the denial of his constitutional rights and to the minute regulation of his conduct by swarms of spies, letter-openers, informers and agents provocateurs that he no longer makes any serious protest.

As quoted in Michael Bakunin (1937) by E.H. Carr, p. 356<!-- New York: NY, Vintage Books -->
Context: I hate Communism because it is the negation of liberty and because humanity is for me unthinkable without liberty. I am not a Communist, because Communism concentrates and swallows up in itself for the benefit of the State all the forces of society, because it inevitably leads to the concentration of property in the hands of the State, whereas I want the abolition of the State, the final eradication of the principle of authority and the patronage proper to the State, which under the pretext of moralizing and civilizing men has hitherto only enslaved, persecuted, exploited and corrupted them. I want to see society and collective or social property organized from below upwards, by way of free association, not from above downwards, by means of any kind of authority whatsoever.
