Analysis of the Poems of William Butler Yeats; When You Are Old, The Isle of Lake Innisfree, The Whooper Swans at Coole, The Second Coming, and Sailing to ByzantiumIn many poems, short stories, plays, television programs, and novels an author usually addresses one main idea in each of his works. One of the main reasons why they do this is because they strongly believe in that idea or that it is somehow related to an important part of their life in general. For example, author Thomas Hardy likes to address the idea of ​​loss in many different ways in his poems, some positive and some negative. William Butler Yeats has one main philosophical idea that he holds to and which he portrays in his poems: he believes that once you die you return as another form of life, this would be rather than a linear view of life, a spherical view of life . Just as Thomas Hardy deals with loss in his poems, William Butler Yeats likes to play with the idea of ​​change and immutability. A critic named Richard Ellmann explains that Yeats's poetry deals with the opposition of both the "world of change" and the world of "immutability." The idea of ​​change or immutability is in fact included in each of Yeat's poems; When You're Old, The Lake Isle of Innisfree, The Wild Swans at Coole, The Second Coming and Sailing to Byzantium. To begin, When You're Old by William Butler Yeats discusses the idea of ​​change in life. In this poem Yeats is a man who is bitter and angry at the way his woman did not want to marry him. He says some harsh things in a loving way and tends to get his point across. His poem begins by saying on page 1140 lines 1-2, “When you are old and gray and sleepy, and nodding by the fire, take this book,” Here is the Yeats record… in the center of the paper. .....nge. Here Yates confuses by stating that he does not want to change, but since human change is always within reach even after death. In conclusion, Yeats appreciates the idea of ​​change and immutability in the world. Yates obviously addresses the idea of ​​change and immutability differently in each of the poems. Some of the ways the idea of ​​change is used can be more optimistic like the poem The Wild Swans at Coole and some are more pessimistic and eye opening like the poem about The Second Coming or Sailing to Byzantium. In any case, critic Richard Ellmann was right in his statement discussed above.
