In this brilliant book, Neuhouser focused on one of the major and important concepts in Rousseau's philosophy: amour-propre. Amour-propre is a kind of self-love that drives humans to seek esteem and admiration from others. In Rousseau's account, amour-propre is the source of all evils that we see in human societies.
Neuhouser, like Kant, considers Rousseau's theory of amour-propre as a theodicy. Theodicy is an explanation of why good God permits evil to exist. In Rousseau's account, human nature is "good" but the social man is corrupted. He articulates that neither human nature nor human conscious will is responsible for evil. But 'the blindness of man' or a lack of knowledge is responsible for evil. In Neuhouser's view, not only does Rousseau show where human evil comes from but also, he proposes social and domestic remedies for averting the dangers of amour-propre (In Émile and the social contract).
In Neuhouser's interpretation, inflated amour-propre is responsible for human evil. But he insists that, in Rousseau's view, extirpation or suppression of amour-propre is not the answer. It means that cultivation of this passion in the human soul and devising social and political institutions properly could avert the dangers of inflated amour-propre. But Neuhouser goes further and claims that amour-propre is a condition for the possibility of rationality, morality, and freedom.
