This paper explores the possibility that Hemingway scholars are overlooking the development of Hemingway as a writer by concentrating too much on the autobiographical elements of his writing. I am not suggesting that scholars ignore the autobiographical aspects of the writing, but rather propose that scholars acknowledge and look for the development of Hemingway's craft of writing in his novels by comparing the early texts with his posthumous works. I have chosen to show this development by comparing A Farewell to Arms and The Garden of Eden, especially through his use of the females characters Catherine in both novels. I assert that whether consciously or unconsciously, Hemingway's reuse of the name Catherine in The Garden of Eden was his attempt to address criticism of his writing by invoking a comparison of the two characters he created in an effort to show how he was able to portray a more sophisticated female character when he was an older, more mature writer. The specific writing tools Hemingway employed to accomplish this task include the use of names, details about the physical appearances of his characters, the vocation of his characters, and the dialogue of his characters.
