Abstract: Due to the poor performance effect and the uncertainty of the ownership of copyright, Yeatss drama The Unicorn from the Stars was neglected by people. From the perspective of literary ethical criticism, this drama, with a focus on Martins identity puzzle and ethical choice, reveals the conflict between rational will, natural will, free will and irrational will of characters. It displays the difficult long journey of Irish people in the pursuit of the dream for hundreds of years. The Unicorn from the Stars embodies Yeatss thought of cultural nationalism, which proved to be morally instructive in the development of Ireland and the whole mankind.

Key words: Yeats, The Unicorn from the Stars, ethical identity, ethical choice, moral teaching

摘要： 叶芝的戏剧《来自星星的独角兽》由于演出效果不佳、作品的作者归属等问题，导致人们对这部作品没有给予足够的重视。但从文学伦理学批评的角度来看，这部戏剧通过马丁的身份困惑和伦理选择，展现了人物身上理性意志与自然意志、自由意志、非理性意志的冲突和博弈，总结了爱尔兰人民数百年来追寻爱尔兰之梦的艰难历程。该剧体现了叶芝的文化民族主义思想, 对爱尔兰和整个人类的发展都有着非常重要的教诲意义。
