［流派概述］存在主义小说是第二次世界大战以后文坛上影响较大的派别之一，它早在３０年代便已出现，后来在加缪与萨特的宣传和介绍下，才在战后真正形成了一个举足轻重的流派。存在主义小说的思想基础是存在主义哲学，小说作者不是存在主义哲学家就是信奉存在主义哲学之人。 [Outline of the genre] Existentialism is one of the most influential factions in the literary world since the Second World War. It appeared as early as the 1930s, but was later promoted and introduced by Camus and Sartre before the end of the war. A truly important school has been formed. The ideological foundation of existentialism novels is existentialism philosophy. The author of the novel is not an existentialist philosopher, who believes in existential philosophy.
