But why need I go back to Aristotle? Did not the slaveowners of the Southern United States maintain the same doctrine, with all the fanaticism with which men cling to the theories that justify their passions and legitimate their personal interests? Did they not call heaven and earth to witness that the dominion of the white man over the black is natural, that the black race is by nature incapable of freedom, and marked out for slavery? some even going so far as to say that the freedom of manual labourers is an unnatural order of things anywhere. No less an intellect, and one which contributed no less to the progress of human thought, than Aristotle, held this opinion without doubt or misgiving and rested it on the same premises on which the same assertion in regard to the dominion of men over women is usually based, namely that there are different natures among mankind, free natures, and slave natures that the Greeks were of a free nature, the barbarian races of Thracians and Asiatics of a slave nature. But was there ever any domination which did not appear natural to those who possessed it? There was a time when the division of mankind into two classes, a small one of masters and a numerous one of slaves, appeared, even to the most cultivated minds, to be a natural, and the only natural, condition of the human race. Some will object, that a comparison cannot fairly be made between the government of the male sex and the forms of unjust power which I have adduced in illustration of it, since these are arbitrary, and the effect of mere usurpation, while it on the contrary is natural. In The Subjection of Women (1869) John Stuart Mill argues that every form of oppression seems perfectly natural to those who live under it, whether it be slavery in the southern states of America or the lack of property and civic rights for women in 19th century Britain: Found in The Collected Works of John Stuart Mill, Volume XXI - Essays on Equality, Law, and Education
