The age of reason.

The Age of Reason (French: L'âge de raison) is a 1945 novel by the philosopher Jean-Paul Sartre. It is the first part of the trilogy The Roads to Freedom. The novel, set in the bohemian Paris in 1938, focuses on three days in the life of philosophy teacher Mathieu who is seeking money to pay for an abortion for his girlfriend, Marcelle. Sartre analyses the motives of various characters and their actions and takes into account the perceptions of others to give the reader a comprehensive picture of the main character. The Age of Reason is concerned with Sartre's conception of freedom as the ultimate aim of human existence. The work seeks to illustrate the existentialist notion of ultimate freedom through presenting a detailed account of the characters' psychologies as they are forced to make significant decisions in their lives. As the novel progresses, character narratives espouse Sartre's view of what it means to be free and how one operates within the framework of society with this philosophy. The novel is a fictional reprise of some of the main themes in his major philosophical study Being and Nothingness (1943). One of the notions is that ultimately a person's freedom is unassailable as it is fundamentally part of the nothingness that is the imagination and so cannot be taken away or destroyed.
