Jean-Jacques Rousseau,
A discourse upon the origin and foundation of the inequality among mankind
(1761)
“ Let us cry up Human Society as much as we please, it will not be the less true that it necessarily engages Men to hate each in proportion as their Interests clash; to do each other apparent Services, and in fact heap upon each other every imaginable Mischief. What are we to think of a Commerce, in which the Interest of every Individual dictates to him Maxims diametrically opposite to those which the Interest of the Community recommends to the Body of Society; a Commerce, in which every Man finds his Account in the Misfortunes of his Neighbour? ”
