“Nothing can illustrate these observations more forcibly, than a recollection of the happy conjuncture of times and circumstances, under which our Republic assumed its rank among the Nations; The foundation of our Empire was not laid in the gloomy age of Ignorance and Superstition, but at an Epoch when the rights of mankind were better understood and more clearly defined, than at any former period, the researches of the human mind, after social happiness, have been carried to a great extent, the Treasures of knowledge, acquired by the labours of Philosophers, Sages and Legislatures, through a long succession of years, are laid open for our use, and their collected wisdom may be happily applied in the Establishment of our forms of Government; the free cultivation of Letters, the unbounded extension of Commerce, the progressive refinement of Manners, the growing liberality of sentiment... have had a meliorating influence on mankind and increased the blessings of Society. At this auspicious period, the United States came into existence as a Nation, and if their Citizens should not be completely free and happy, the fault will be entirely their own.

[Circular to the States, 8 June 1783 - Writings 26:484--89]”

“As Mankind becomes more liberal, they will be more apt to allow that all those who conduct themselves as worthy members of the community are equally entitled to the protections of civil government. I hope ever to see America among the foremost nations of justice and liberality.”
― George Washington
