本文首先討論孤獨、自由與鄭愁予詩作的關係。貫串於其一生詩中的,隱含着一個精神(遊/俠精神)、兩個觀點(虛無/殉道),以及四種面向:面向個人時,是浪子;面向人間時,是情俠、是仁俠(儒俠);面向宇宙時,是無常觀;面向語言時,是「俠之最高形式的遊」,也是最高形式的自由。「遊」是形式,「俠」是「憂」是動力;「遊」是內外空間的拓延和探勘,「俠」是時間的悲憫凝視和綻放;詩則是此「時空因緣和合」的人間之花,實即宇宙之花,遊/俠精神即隱匿的宇宙精神。其次討論此精神在時空中的三度轉折:起先是於「他在他為」的時空中設下象徵(障礙及變形);其後是在「自在自為」的時空中付諸實踐,一度成為著人議論的靈魂;最後是在「無在無為」的時空中朝向生命的冥合境界、建構自身的生命美學。此精神之極致表現是:殉於詩、殉於美(包括性)、殉於「一」。
This essay discusses the relationship among loneliness, freedom and Zheng Chou-Yu's poetry. There are one spirit, two viewpoints and four aspects connecting his works. He is a wanderer when facing himself, and a chivalrous person while facing society. He holds the sense of ”anicca” towards the universe and performs ”the most advanced travel of chivalrous person”, which is the highest level of freedom, when he is writing poems. This essay then discusses the three dimensional inflextion of Zheng's spirit within the time and space. The ultimate manifestation of this spirit is sacrificing for poetry, for beauty (including sex) and for ”one”.
