 Rousseau thought that "amour-propre" was subject to corruption, thereby causing vice and misery.The term "amour-propre" predates Rousseau and is found in the writings of Blaise Pascal, La Rochefoucauld, Pierre Nicole, Jacques Abbadie and many others.Pascal detested self love, self esteem, ego, vanity as well perhaps, which are interchangeable terms for him, because it puts the self in the place of God.
