본 논문은 윌리엄 버틀러 예이츠(W. B. Yeats)의 시 나는 그대의 주 (“Ego Dominus Tuus”)에 나타난 니체적 예술관과 자아 이론을 분석한다. 예이츠는 니 체의 사상을 긍정하며 자아와 반자아의 갈등을 창조적 에너지로 전환하고, 이를 통해 예술적 자아와 이상적 삶의 가능성을 탐구한다. 본 논문은 예이츠가 마스크 이론(Mask theory)을 통해 자아를 재구성하고자 한 의도를 조명하며, 자아의 분열과 대립을 예술 적 이상화 과정의 필수적 요소로 이해했음을 논의한다. 또한, 나는 그대의 주 에 나타 난 예이츠의 창조적 긴장과 자아의 변형 과정을 통해, 그의 시 세계가 지향하는 이상 적 삶과 예술의 상호작용을 규명한다. 이를 통해 예이츠가 니체의 예술로서의 삶을 어 떻게 자신의 시적 비전에 통합했는지를 밝힌다.

Per Amica Silentia Lunae (Yeats translated it into Through the Friendly Silences of Moon) was written between January and May of 1917, and consists of a Prologue and an Epilogue for Iseult Gonne, "Ego Dominus Tuss," Anima Hominis and Anima Mundi. In Anima Mundi Yeats said, "I have always sought to bring my mind close to the mind of Indian and Japanese poets, old women in Connacht, mediums in Soho, lay brothers whom I imagine dreaming in some mediaeval monastery the dreams of their village, learned authors who refer all to antiquity: to immerse it in the general mind where that mind is scarce separable from what we have began to call 'the subconscious'... ." In the background of his theory of anti-self there are Indian and Japanese Religious thought, Celtic folklore, Spiritualism, the Order of Golden Dawn, and the great poet Dante. "Ego Dominus Tuss" is a dialogue between two men, Hic and Ille, who discuss poetry and creative process. Ille, like Yeats, is a daimonic poet walking in the moonlight. For Yeats, lunar and subjective were always the antitheses to solar and objective. Poesis called for complete subjectivity, for entry into the friendly silence of the moon. The moon is always associated with feminine divinity. With the help of a mask, Ille is calling to the opposite of his daily self, his anti-self. In the end of the poem, Ille found his anti-self. In Anima Hominis Yeats said that the saint like Christ and Buddha, and the poets like Dante and Keats attained the anti-self. The anti-self is a egoless self, the higher self. Saint, hero, and poet are all inspired. Yeats said, "Saint or hero works in his own flesh and blood and not in paper or parchment, have more deliberate understanding of that other flesh and blood." Only when Yeats became the anti-self could he become a totally subjective mind, overcome the illusion of duality, and find a "revelation of realty." Yeats could receive daimonic inspiration only during visionary experiences. Finally Yeats found the anti-self he felt ecstasy. According to his theory, the production of art was an expression of the artist's longing for "Unity of Being." In Per Amica silentia Lunae Yeats said "the poet, because he may not stand within the sacred house but lives amid the whirlwinds that beset its threshold, may find his pardon."
