叶芝是希腊思想的热枕信仰者，他相信，正是通过创造和艺术才可激发、激活一个人的“意志”，而意志反过来又诉诸悲剧美来面对和战胜痛苦。叶芝的一首诗《库勒的野天鹅》即为典例，它有着可惧却愉悦的美。在这首诗中，诗人用他朴素的语言、深厚的哲思，讲述了他生命对艺术永恒的关注。失落感、瞬间的怀旧和对昔日爱情的沉思被宣泄出来。此外，叶芝抓住了时间的停顿和流动，他将动静巧妙地结合在一起，传达了一种如画的艺术美感。在这首诗中，天鹅的形象唤起了他的沉思和痛苦，如同醉梦。然而，深深浸淫了希腊和尼采乐观的悲剧思想的叶芝最终接受了变迁的不可避性，内心变得恬淡。在本文中，笔者将解释叶芝在这首诗中对尼采思想的反映，并对叶芝反复跳动但最终不可动摇的乐观主义即超人思想进行解剖。

W. B. Yeats, an earnest devotee of Greek thoughts, believes that it is by creation and art to energize or activate one’s “will”, which in turn, resorts a tragic beauty to face and fight against agony. One of Yeats’ poem “Wild Swan at Coole” is of no exception of such terrible but pleasant beauty. In this poem, the poet, (also the homodiegetic narrator), with his chastity of diction and deep philosophy ideas, relates to one constant concern in his life- the art, in which a sense of loss, instantaneous nostalgia and contemplation of the erstwhile love are expressly given a vent to. What’s more, Yeats grasped the pause and flux of time, with his delicate combination of stillness and motion, conveyed a picturesque and artistic sense of beauty. In this poem, it is the image of swans that evoked his meditation and agony as if he had been drunk. However, deeply tinged with Greek and Nietzsche’s buoyant idea of tragedy, Yeats in the end accepted the inexorability of change and enjoyed a treasured tranquil inner peace. In this paper, the author is going to interpret Yeats’ reflection of Nietzsche’s thought in this poem and plays an autopsy on Yeats’ twisted but finally unshaken optimism or superman philosophy.
