本篇論文想離開傳統哲學或神學觀點,重新理解作為事實性此有(Factical Dasein)的奧古斯丁是如何從存有論的科學(ontological science)轉向存有者的科學(ontic science)來建構自己的世界觀。筆者主要透過海德格早期在《宗教生活現象學》中所提及的形式指引(Formal indication)方法討論聖奧古斯丁的轉宗經驗(conversion experience)。其主要論述的走向為,根據奧古斯丁在《懺悔錄》第十冊當中描述世俗世界的三種誘惑(desire of flesh, curiosity, be feared and loved) 配合海德格的事實性生活經驗(Factical life experience)的三層世界(surrounding world, communal world, self-world),爬梳奧古斯丁如何透過自身存有論式(ontological)的語言踐行(the enactment of language)逐步在共同世界中建構一個屬己歷史(ownmost history)的前信仰世界觀(pre-faithful worldview),接著又如何因為好奇的踐行(the enactment of curiosity)逐漸消耗屬己歷史的可能性(possibility),最後接納非屬己的歷史-基督的歷史事件以及其共同世界(communal world)的語言,進而以存有者式的語言踐行構成傳統意義上基督神學的世界觀。
This thesis wants to leave the traditional philosophical or theological viewpoint and rediscover how Augustine, as factical Dasein, turned from ontological science to ontic science to constitute his own worldview. I mainly discuss St. Augustine’s conversion experience through the method of formal indication mentioned in Heidegger’s early work Phenomenology of Religious Life (1921). The main thread of my discussion is based on Augustine’s description of the three temptations of the secular world in the tenth book of Confessions in conjunction with Heidegger’s three-level lifeworld reading through how Augustine uses the verbal enactment to constitute his pre-faithful worldview. Eventually, because of the enactment of curiosity gradually consumed the possibility of his ownmost history, and finally accepted the Christian history, and then having the verbal enactment to constitute a traditional theological worldview.
