Freedom, can never be restored. Liberty once lost is lost forever.

John Adams, letter to Abigail Adams, 1775

Some good quotes.

The moment the idea is admitted into society that property is not as sacred as the laws of God, and that there is not a force of law and public justice to protect it, anarchy and tyranny commence. If 'Thou shalt not covet' and 'Thou shalt not steal' were not commandments of Heaven, they must be made inviolable precepts in every society before it can be civilized or made free.

John Adams, A Defense of the American Constitutions, 1787


[L]iberty must at all hazards be supported. We have a right to it, derived from our Maker. But if we had not, our fathers have earned and bought it for us, at the expense of their ease, their estates, their pleasure, and their blood.

John Adams, A Dissertation on the Canon and Feudal Law, 1765


[D]emocracy will soon degenerate into an anarchy, such an anarchy that every man will do what is right in his own eyes and no man's life or property or reputation or liberty will be secure, and every one of these will soon mould itself into a system of subordination of all the moral virtues and intellectual abilities, all the powers of wealth, beauty, wit and science, to the wanton pleasures, the capricious will, and the execrable cruelty of one or a very few.

John Adams, An Essay on Man's Lust for Power, 1763


It has ever been my hobby-horse to see rising in America an empire of liberty, and a prospect of two or three hundred millions of freemen, without one noble or one king among them. You say it is impossible. If I should agree with you in this, I would still say, let us try the experiment, and preserve our equality as long as we can.

John Adams, letter to Count Sarsfield, February 3, 1786

History affords us many instances of the ruin of states, by the prosecution of measures ill suited to the temper and genius of their people. The ordaining of laws in favor of one part of the nation, to the prejudice and oppression of another, is certainly the most erroneous and mistaken policy. An equal dispensation of protection, rights, privileges, and advantages, is what every part is entitled to, and ought to enjoy... These measures never fail to create great and violent jealousies and animosities between the people favored and the people oppressed; whence a total separation of affections, interests, political obligations, and all manner of connections, by which the whole state is weakened.

Benjamin Franklin

That's obviously false.  If it were so, we would never again have had any free countries once the last of the egalitarian hunter-gatherer societies gave way to autocratic agrarian kingdoms back in the early Bronze Age.
