There is a liberty of a corrupt nature which is effected both by men and beasts to do what they list, and this liberty is inconsistent with authority, impatient of all restraint; by this liberty ‘sumus omnes deteriores’: ‘tis the grand enemy of truth and peace, and all the ordinances of God are bent against it. But there is a civil, a moral, a federal liberty which is the proper end and object of authority; it is a liberty for that only which is just and good. For this liberty you are to stand with the hazard of your very lives and whoever crosses it is not authority, but a distemper thereof.-- Tocqueville, Democracy in America, Vol. 1 (1835). [Via: Michael Novak].
While our country remains untainted with the principles and manners which are now producing desolation in so many parts of the world; while she continues sincere, and incapable of insidious and impious policy, we shall have the strongest reason to rejoice in the local destination assigned us by Providence. But should the people of America once become capable of that deep simulation towards one another, and towards foreign nations, which assumes the language of justice and moderation while it is practising iniquity and extravagance, and displays in the most captivating manner the charming pictures of candor, frankness, and sincerity, while it is rioting in rapine and insolence, this country will be the most miserable habitation in the world; because we have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge, or gallantry, would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.
John Adams, "To the Officers of the First Brigade of the Third Division of the Militia of Massachusetts". 11 October 1978.
