Symbols are loaded with important meanings. So if a symbol appears repeatedly or at important moments, it may point to the theme of the novel. A good example is the letter “A” in The Scarlet Letter.Since a theme is different from a moral or a lesson, one should avoid reducing a theme to a clich233。Finally, the theme is not to be confused with the subject. The theme is an idea while the subject is a matter or an affair. “Love is invincible” may be a theme, but “l(fā)ove” is only a subject. A subject may be universal. The subjects of The Scarlet Letter, The Great Gatsby, and Women in Love are all “l(fā)ove.” But these novels have different themes. A theme is particular to its novel, though there are many similar themes to be found in other novels.So the theme of a story, then, is whatever general idea or insight the entire story reveals. Foil characters are ones that help enhance the intensity of the hero by strengthening or Aristotle in Poetics lists six basic elements of tragedy. Melody (song) and diction (language) fall in the general category of style, and spectacle is relevant to setting in our discussion of fiction. The other three aspects are mythos or plot, ethos or character, and dianoia, which we generally translate into “thought” in English. According to Aristotle, plot is the “soul” or shaping principle or fiction, and characters exist primarily as functions of the plot. In most of the stories, plot plays the role of principal structure of the story. But, as Northrop Frye points out, besides the internal fiction of the character and his/her society, there is an external fiction consisting of a relation between the writer and the writer’s society. We indeed have literary works by the likes of Shakespeare and Homer in which artistry is pletely absorbed in their internal characters and we can hardly perceive the existence of the author. However, as soon as the author’s personality appears on the horizon, a relation with the reader is established, and sometimes there seems no story at all apart from what the author is conveying to his/her reader. In this case, the primary interest in dianoia, the idea or thought that reader gets from the writer, which in modern criticism we generally call “theme”.people discard the novel when they think that they have got the theme. It should be made clear that the novel is not written to convey an idea but to convey an idea artistically. The novel is a work of art whereas the theme is only an abstract idea. An analogy from daily life may help clarify this question. People all need vitamins and get them from various kinds of vegetables and fruits. Only those with deficiency of one kind or another have to take vitamin pills to get the required amount. The difference between the theme and the novel is much like that between the vitamins and the vegetables. The reader sometimes finds that the theme of a novel is simila
