John Adams: Where Our Rights Really Come From

"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."
--John Adams, Rights of the Colonists, 1772
