Nausea, The Result of Existence In Jean Paul Sartre’s latest novel, Nausea, he presents the idea that “existence precedes essence.” In other words, he is using the novel as a way to say that things exist but that we give things meaning based on our own actions. To do this Sartre uses Antoine Roquentin as the main protagonist. Roquentin is painted to suffer from ‘nausea’ of unknown origin at the beginning of the novel. Later it is learned that this nausea stems from the moments when Roquentin realizes he is creating essence of objects. Sartre allows the reader to follow Antoine Roquentin through his journey to discover the cause of the nausea and cope with the idea that existence precedes essence. Through his journey to find the cause of the nausea, the reader follows along in Roquentin’s journal. He starts off by acknowledging the customers in Café Mably. According to Roquentin, “in order to exist, they also must consort with others.” But he does not talk to anyone. Instead he talks about how he lives entirely alone. Throughout the novel the reader learns this is not entirely true. Roquentin chooses to not rely on words to describe objects and instead lets events low past him.
