“What then is Liberty? Liberty, I would answer, so far as it is possible for it to exist in a Society of Beings whose interests are almost perpetually opposed to each other, consists in this, that, every Man, while he respects the persons of others, and allows them quietly to enjoy the produce of their industry, be certain himself likewise to enjoy the produce of his own industry, and that his person be also secure. But to contribute by one’s suffrage to procure these advantages to the Community,—to have a share in establishing that order, that general arrangement of things, by means of which an individual, lost as it were in the croud, is effectually protected,—to lay down the rules to be observed by those who, being invested with a considerable power, are charged with the defence of individuals, and provide that they should never transgress them,—these are functions, are acts of Government, but not constituent parts of 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.
