Nausea is both the story of the troubled life of a young writer, Antoine Roquentin, and an exposition of one of the most influential and significant philosophical attitudes of modern times - existentialism. The book chronicles his struggle with the realization that he is an entirely free agent in a world devoid of meaning; a world in which he must find his own purpose and then take total responsibility for his choices. A seminal work of contemporary literary philosophy, Nausea evokes and examines the dizzying angst that can come from simply trying to live.
