The French philosopher Serge Audier has perhaps become the leading authority on the history of liberalism in France. However, he is largely unknown in the United States. This article attempts to provide the first critical overview of Audier's work in English. It does so by suggesting that the major aim of Audier's work is to revive a forgotten strand of social liberalism in France. The article illustrates this by looking at Audier's writings on the works of Léon Bourgeois and Raymond Aron and also his critical studies on the history of neoliberalism in France and beyond.
