To Kill a Mockingbird, War and Peace, The Grapes of Wrath, The Lord of the Rings, Murder on the Orient Express, whatever your current and longtime favorite fiction may be: where do such great stories come from? Whether a story comes largely from the writer’s imagination or directly from true life experience, great works of fiction are never just raw reports of events, whether real-life or imagined. Every fiction is shaped by a multitude of artistic choices designed to give readers an experience, a sense of craft, or even beauty. Often, a great novel or short story shares a new way of thinking about life. In fact, most fiction we cherish as classic is shaped by interesting and weighty ideas. To enjoy these works to the fullest, be on the lookout for ideas that guide the narrative—in other words, its Themes.
