歐大旭在《沒有地圖的世界》中探討以下議題：在一個後殖民的社會，「家」應該被怎麼定義。本論文旨在探討原文標題中「隱形世界」(the Invisible World)的真意，試圖從主角亞當的故事中，了解歐大旭是否能在「隱形世界」中，標誌出屬於他的家園。論文由空間的角度切入，探討國家空間和家屋各自對身份認同的影響。第一章首先檢視印尼國家整體的空間與民族主義的關係。印尼複雜的組成和歷史導致印尼人對國族家園有不同的想像和認同。然而「想像」的任意性，卻可為新興國家開啟一條共生共榮的道路。第二章說明家屋對身份認同的影響。亞當做為移民—甚至是前殖民主—的第二代，肩負橋樑的職責，他從邊緣來到中心，為印尼帶來新的元素。亞當代表了印尼的過去，印尼只有接受他，擁抱他，才能成就一個真正的國家。第三章將前兩章的國家認同及個人認同連結，討論書中隱形世界的意義和時間的意象。
　　經過二十世紀前半葉的大戰後，世界出現了許多剛脫離殖民的新興國家，這些新興國家及當中的人民如何建立認同，已成許多小說的主題。許多離散及移民主體對於認同及家園的尋找產生焦慮，歐大旭也不例外。他的書寫便是他尋找家的過程，而從他的字裡行間，我們可以了解，對於在地圖上標誌出家園一事，他抱持著一種謹慎的樂觀：唯有擁抱過去，才能擁有共同的未來，此事各國皆然。

This paper centers on two questions raised in Tash Aw’s second novel Map of the Invisible World: As a Malaysia diaspora, why does Aw write a story about Indonesia? Moreover, what and where is this invisible world and what does it imply? By looking into these questions, we will be able to learn what Aw regards as a homeland.
In order to answer these questions, I first borrow Benedict Anderson’s imagined communities to investigate the concepts of nation, nationality and nationalism. Following the first chapter, I move my focus from the nation to individual, adopting Gaston Bachelard’s theory of the house to define what a home is to the protagonist Adam. In the final chapter I use Homi K. Bhabha’s theory of newness to define Aw’s invisible world—the invisible world is the beyond that links the novel’s future with the present in the real world. With the intervention of the beyond to the now, Aw brings the everlasting identity issues from the range of a nation into a whole world, and is thus able to rewrite or redefine our past.
Writing the plight of Adam and Indonesia, Aw is in effect revealing his own anxiety about locating himself in the world. Through writing, Aw offers a revision of the history, which makes it possible for him and people in the modern world to find a homeland of their own.
