Nausea is both the story of the troubled life of an introspective historian, 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 realisation 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.
