溫特森最新的實驗小說《魔力書》，以網際空間為喻，探討性自由與權力之間的關係；是一本因應千禧年而誕生的作品。故事中的主人翁阿里(Ali)，藉由答覆網上不知名的筆友，為讀者揭示女性主體及性慾自主的議題；作者巧妙地將自己擅長的詩意散文、新奇敘事體，融入哲學思維，與網際網路天馬行空的力量相結合。本論文旨在以宏觀哲學的角度分析女性各個不同時期的處境，並指出《魔力書》除了充溢智慧、想像、力量之外，是一本關切女性處境及主體的小說。 本論文以西蒙•波娃有關女性主體論述為主要理論架構。論文主體可分三部分。第一部分旨在分析權力關係的影響，並以書中網路外遇事件為例，彰顯出已婚女性受傳統意識型態箝制，失去性自主的契機。第二部分從敘事者的角度，以女性特有言說方式，持續探討女性情慾自主的議題。最後一部分處理敘事者不同形式的存在模式，並以宏觀角度分析，不同時期(神話、奇想、網際空間)女性主體的變化性。 對照四十年前的女性處境，處於科技時代的摩登女性仍然受制於傳統女性特質的制約，或是受到強勢意識型態所掌控。面對此情境，女性應藉由參與社會或政治活動，承擔起改變世界的責任，來確保個人主體性的完整；女性應對自我有更多的期許及要求。溫特森在《魔力書》中藉由答覆網路筆友的要求─「自由，給我一晚的自由」─其實真正探討的是確立女性主體性的重要概念。 / Winterson’s latest novel The PowerBook (2000) is an experimental work of fiction that uses the metaphor of cyberspace to portray the issue of sexual freedom and power, a book that greets the challenge of the new millennium in Winterson’s design. By answering to an unknown on-line correspondent’s need, the narrator and e-mail writer Ali explores the very issue on women’s subjectivity and the autonomy of femininity, adroitly connecting the power of the Internet (the imaginary and the virtual) with her poetic prose and inventive narrative in conjunction with philosophical significance. My thesis aims to start a complicated analysis of women’s different situations from a philosophical perspective. I think The PowerBook, invested with wisdom, imagination and power, is a book that concentrates on women’s situation and subjectivity. Simone de Beauvoir’s concept on women’s subjectivity constitutes the most important theoretical framework of my thesis. The main body of the thesis can be grouped into three parts. Firstly, I will probe the effect of power relations on a virtual forbidden love affair, manifesting that the married woman is manipulated by the patriarchal ideology so that she ultimately fails to fulfill her autonomy of femininity. Secondly, I will discuss, mainly in terms of a feminist discourse theory, the issue on the autonomy of femininity revealed in Ali’s narrative. Thirdly, the last section of the main body will not only deal with Ali’s various modes of existence, but also aim at exploring women’s selfhood in respect of myth, fantasy and cyberspace. By contrasting women’s situation at present with that almost forty years ago, I will show that modern women in the technological age are still either bound by the myth of femininity, or conditioned by dominant ideologies. Finally, I will conclude that modern women should not only act as independent subjects, but also demand more and expect more for themselves. By participating in social and political activities, they are able to take the responsibilities for improving the world. It can be interpreted that to answer to the correspondent’s need—“Freedom, just for one night”—is actually to examine the main subject on women’s existence in Winterson’s intention.
