T. S. Eliot`s last play, The Elder Statesman shows the self-realization of the main character Lord Claverton. He was a successful statesman in the past, and suffers the severe problem of identity now. He is harassed by his former friends named Gomez and Mrs. Carghill who make him recall his past. His son, Michael, makes Lord Claverton think of his past, too. This paper focuses on the names of the characters and the change of names in the play. The main character, Lord Claverton changed his name twice, one of his old friends, Gomez once and Mrs. Carghill twice. His son Michael is likely to change his name sooner or later, after he goes abroad. The reason to examine the change of the names is that the change reflects Lord Claverton`s self-realization. Eliot declare that naming is not an easy thing in the poem `The Naming of Cats`. Eliot`s friend Browne told that Eliot was very careful of naming characters in The Elder Stateman. Furthermore, the original name of this play was The Rest Cure and the other alternative was The Man Who Changed His Name. This is enough evidence that Eliot was very conscious of the names of the characters in the play. This play shows the recovery of Lord Claverton`s self through the implication of changing names. His old friends help him to recover his self by calling him by his old names. His son Michael gives him final stroke to realize his self by trying to go abroad and change his name. While Lord Claverton gives advice to his son, he explains the meaning of changing names. And that brings him his self-realization. Through many people`s help, Lord Claverton recovers his self and gets peace in the long run.
