Nausea (French: La Nausée) is a philosophical novel by the existentialist philosopher Jean-Paul Sartre, published in 1938. It is Sartre's first novel and, in his own opinion, one of his best works.
The novel takes place in 'Bouville' (homophone of Boue-ville, literally, 'Mud town') a town similar to Le Havre, and it concerns a dejected historian, who becomes convinced that inanimate objects and situations encroach on his ability to define himself, on his intellectual and spiritual freedom, evoking in the protagonist a sense of nausea.
French writer Simone de Beauvoir, Sartre's lifelong partner, argues that La Nausée grants consciousness a remarkable independence and gives reality the full weight of its sense. It is one of the canonical works of existentialism.
In 1964 Sartre was awarded the Nobel Prize for literature, but he ultimately declined to accept it. The Nobel Foundation recognized him "for his work which, rich in ideas and filled with the spirit of freedom and the quest for truth, has exerted a far-reaching influence on our age." Sartre was one of the few people to have declined the award, referring to it as merely a function of a bourgeois institution.
The novel has been translated into English at least twice, by Lloyd Alexander as The Diary of Antoine Roquentin (John Lehmann Limited, 1949) and by Robert Baldick as Nausea (Penguin Books, 1965).
