Although amour propre has its origins in sexual competition and comparison within small societies, it does not achieve its full toxicity until it is combined with a growth in material interdependence among human beings. In the Discourse on Inequality, Rousseau traces the growth of agriculture and metallurgy and the first establishment of private property, together with the emergence of inequality between those who own land and those who do not. In an unequal society, human beings who need both the social good of recognition and such material goods as food, warmth, etc. become enmeshed in social relations that are inimical both to their freedom and to their sense of self worth. Subordinates need superordinates in order to have access to the means of life; superordinates need subordinates to work for them and also to give them the recognition they crave. In such a structure there is a clear incentive for people to misrepresent their true beliefs and desires in order to attain their ends. Thus, even those who receive the apparent love and adulation of their inferiors cannot thereby find satisfaction for their amour propre. This trope of misrepresentation and frustration receives its clearest treatment in Rousseau's account of the figure of the European minister, towards the end of the Discourse on Inequality, a figure whose need to flatter others in order to secure his own wants leads to his alienation from his own self.
