從「真如緣起」到「法界緣起」的進路－「一心」觀念的確立

在中國大乘佛學思想中，華嚴宗的「法界緣起觀」，可以說是最其有中國思惟特色的佛教哲學。〈華嚴經〉中也常吉道：三界虛妄，唯是一心作。這種把一心看作是顯現「法界緣起」的真心觀念，更不禁讓人對佛教的形上學系統，產生一股油然的欽佩之情！然而，一個思想的產生，它絕對不可能是孤立而起或一頓即成的；換言之：佛教的思想發展，也必須要有一段漫長的思想史背景作為蘊釀，最後才會開花結果，枝葉茂盛。因此，從思想史的角度而言：華嚴思想雖然是體系龐雜，牽涉的範閏甚廣，但總有一條思想史的脈絡可循！而本論文的寫作目的，便是希望能透過「思想史的溯還法」，分別探討「法界緣起」「真如緣起」之間的思想關僚，作為整個「法界緣起」的思想序曲。事實上，「法界緣起」的思想,主要是以前期的「業感緣起」、「賴耶緣起」、「真如緣起」乃至「如來藏緣起」作為理論的伏線。因此，研究「法界緣起」的思想史，事實上，就等於在研究「緣起」思想，在不同時期的詮釋史；由於佛教的「緣起」思想，在不同時期當中，就分別有不同的詮釋態度，所以，集合了這不同時期的詮釋內容，便正好構成了整個「緣起」思想的詮釋史。

As we know the idea of Dharma-Dhatu-Pratitya-Samutpada ( 法界緣起 ) Hua-Yen Buddhism is a kind of ＂Chinese style thinking＂ Buddhist philosophy in Chinese Mahayana Buddhism. The Gandavyuha-sutra always said ＂the three categories of life ( tri-dhatu；三界 ) is unreal, they are only created by one-mind ( eka-citta；一心 )＂ ( 三界虛妄，唯是一心作 ). Therefore, this one-mind seen as a real-mind to generate the Dharma-Dhatu-Pratitya-Samutpada ( the relative existence of the world), so we may feel very surprise to those metaphysical systems of Buddhism. However, it is impossible for the isolation or the great jump of the formation of idea, in other words, the formation of the idea of Buddhism must depend on the long historical development. According to the historical view, even though the structure of the idea of Hua-Yen Buddhism is very complicated, indeed, we still believe that we can also find out the historical route of the idea. So the end of this Dissertation is trying to find out the historical route of the idea between Dharma-Dhatu-Pratitya-Samutpada and Tathata-Pratitya-samutpada ( 真如緣起 ) by the historical reductive method. Therefore, the idea of Dharma-Dhatu-Pratitya-Samutpada really depents on the long historical development of Karma- Pratitya-Samutpada ( 業感緣起 ), Alaya- Pratitya- Samutpada ( 賴耶緣起 ), Tathata-Pratitya-Samutpada ( 真如緣起 ), even of the Tath ata-Pratitya-Samutpada. In this way, the historical research of Dharma-Dhatu-Prati tya-Samutpada is equal to the ＂Hemeneutical History of Pratitya-Samutpada＂ ( 緣起的詮釋史 ), indeed. So the ＂Hemeneutical History of Pratitya-Samutpada＂ represents the different explanation of Pratitya-Samutpada ( 緣起 ) in different historical ages.
