Discourse Upon The Origin And The Foundation Of The Inequality Among Mankind

A Discourse Upon The Origin And The Foundation Of The Inequality Among Mankind is a classic political science text on the subjects of natural law and equality by the great French wrter and philosopher Jean-Jacques Rousseau.
"'Tis of man I am to speak; and the very question, in answer to which I am to speak of him, sufficiently informs me that I am going to speak to men; for to those alone, who are not afraid of honouring truth, it belongs to propose discussions of this kind. I shall therefore maintain with confidence the cause of mankind before the sages, who invite me to stand up in its defence; and I shall think myself happy, if I can but behave in a manner not unworthy of my subject and of my judges.
I conceive two species of inequality among men; one which I call natural,or physical inequality, because it is established by nature, and consists in the difference of age, health, bodily strength, and the qualities of the mind, or of the soul; the other which may be termed moral, or political inequality, because it depends on a kind of convention, and is established, or at least authorized, by the common consent of mankind. This species of inequality consists in the different privileges, which some men enjoy, to the prejudice of others, such as that of being richer, more honoured, more powerful, and even that of exacting obedience from them."
