"I am apt to suspect the Negroes, and in general all the other species of men, to be naturally inferior to whites. There never was any civilized nation of any other complexion than white, nor even any individual eminent in action or speculation. No ingenious manufactures among them, no arts, no sciences....Such a uniform and constant difference could not happen, in so many countries and ages, if nature had not made an original distinction betwixt the breeds of men."
