"Regarding slavery... that slow poison, which is daily contaminating the minds and morals of our people. Every gentlemen here is born a petty tyrant. Practiced in acts of despotism and cruelty, we become callous to the dictates of humanity, and all the finer feelings of the soul. Taught to regard a part of our own species in the most abject and contemptible degree below us, we lose that idea of the dignity of man, which the hand of nature had implanted in us, for great and useful purposes... George Mason, July 1773"
