璜．荷西．米亞斯(Juan Jose Millas, 1946-)被批評家一致認為是當今西班牙文壇中最傑出的作家之一，他大部份的作品皆探討文學、寫作及批評等理論性之主題。本文的主旨在於分析真實、虛構與後設小說如何運用於璜．荷西．米亞斯的暢銷小說－《你那紊亂的名字》(El desorden de tu nombre, 1988)，而本論文將針對作品的結構、人物及主題等部份作深入的討論。《你那紊亂的名字》試圖證明文學是真實與虛構的再創造。真實、虛構與後設小說在本作品裏時而並列共存，時而錯綜複雜地困惑讀者。藉著小說主角胡利歐．歐爾卡思(Julio Orgaz)的故事，米亞斯玩弄"真實"的生活與"虛構"的生活兩者平行交錯的概念，他們的巧合，完全歸於後設小說的運用，透過後設小說，作者跨越生活與文學，真實與虛構的邊界。 Juan Jose Millas(1946- ) has been considered by the critics as one of the leading writers in the contemporary Spain and most of his works center on theoretical reflections on literature, writing and criticism. The present study aims to analyze how reality, fiction and metafiction function in El desorden de tu nombre (The Disorder of Your Name, 1988), the most popular novel by Millas, in terms of the structure, characters and themes. El desorden de tu nombre attempts to show us that literature is the re-creation of reality and fiction/imagination. The conclusion proposes that the elements of reality, fiction and metafiction in the novel are juxtaposed as well as correlated intricately. Through the story of the main character, Julio Orgaz, Millas plays with the idea of the "real" life parallel to the "fictional" life, whose coincidences are attributed to the use of metafiction, which allows the writer to break the borders between life and literature, between reality and fiction.
