The Declaration of Independence announces the sublime truth, that all power comes from the people. This was a denial, and the first denial of a nation, of the infamous dogma that God confers the right upon one man to govern others. It was the first grand assertion of the dignity of the human race. It declared the governed to be the source of power, and in fact denied the authority of any and all gods. Through the ages of slavery — through the weary centuries of the lash and chain, God was the acknowledged ruler of the world. To enthrone man, was to dethrone God.
— Robert Ingersoll, Individuality, 1873
