图书馆、书和词语是博尔赫斯用以表现世界本质的系列象征。《巴别图书馆》 表现了博尔赫斯的宇宙模式，《沙之书》等小说视“书”为世界之本质，“唯一的词”则是 博尔赫斯在作品中浓墨重彩追问的万物本源。图书馆、书和词语这一系列意象的形成受到 犹太神秘主义派别喀巴拉的影响，同时，博尔赫斯的唯心主义世界观和神秘主义倾向是其 哲学基础。 Libraries, books and words are a series of symbols that Borges uses to express the essence of the world. The Babel Library expresses the cosmic pattern of Borges. The novels such as The Book of Sa regards the book as the essence of the world, and the only word is Borges’s thoroughgoing inquiry in his works origin. The formation of a series of images of libraries, books and words is influenced by the Jewish mystic sect Kashala, while Borges’s idealist world outlook and mysticism are its philosophical foundations.
