To understand Yeats’s death we should know his concept of daimonism. Yeats’s daimonism was deeply rooted in folklore and mythology. He came to create a daimonism of his own which could provide the scaffolding for his thought and artistic expression. So it shapes a coherent pattern of present and past life. In Yeats’s poetry, the existence of daimon was a great source, a medium of the recreation between soul and body, racial instinct and spirit, the life and death. To Yeats death is a part of “Great Wheel” in “Unity of Being”. Yeats’s damonism is a symbol of perfection and visionary passion of unconsciousness, which grew out of the microcosm and the macrocosm in his poetry. The main function of death in Yeats’s poetry connects reincarnation of our eternity world and rebirth of human being. T. S. Eliot tends to begin his poems with quotations and echoing passages from other philosophies, thoughts, religions and one’s experiences by fusing these ones into the concept of death. Especially, The Waste Land has no narrative and no unifying central character. There is only a heap of broken death images and inaudible voices. The Waste Land juxtaposes various different voices of “Death of Island”. As in inaudible “death” voices, the main tunes and pattern of notes are hinted at, elaborated on, and returned to. We conclude that the unified consciousness is not Eliot’s but the reader’s. In Eliot’s poetry, death stands as a commitment to his search for a universal text by way of deconstruction for reconstruction.
