"If men through fear, fraud or mistake, should in terms renounce and give up any essential natural right, the eternal law of reason and the great end of society, would absolutely vacate such renunciation; the right to freedom being the gift of God Almighty, it is not in the power of Man to alienate this gift, and voluntarily become a slave."

-- Samuel Adams, Rights of the Colonists, 1772
 
 
"All, too, will bear in mind this sacred principle, that though the will of the majority is in all cases to prevail, that will to be rightful must be reasonable; that the minority possess their equal rights, which equal law must protect, and to violate would be oppression."

-- Thomas Jefferson, First Inaugural Address, 1801


 
 
"In disquisitions of every kind there are certain primary truths, or first principles, upon which all subsequent reasoning must depend."

-- Alexander Hamilton, Federalist No. 31, 1788


 
 
"Excessive taxation ... will carry reason and reflection to every man's door, and particularly in the hour of election." 

-- Thomas Jefferson

 
 
"Freedom had been hunted round the globe; reason was considered as rebellion; and the slavery of fear had made men afraid to think. But such is the irresistible nature of truth, that all it asks, and all it wants, is the liberty of appearing."

--Thomas Paine, Rights of Man, 1791

 
 
"Man, once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. With such persons, gullibility, which they call faith, takes the helm from the hand of reason and the mind becomes a wreck."

--Thomas Jefferson, letter to James Smith, 1822
