Let's start first with some basics of thesis writing. According to a basic definition of the concept of thesis, it is a "statement or theory that is put forward as a premise to be maintained or proved." But we really want to take this a step further. According to Marcie Sims, a colleague of mine. in her textbook, THE WRITE STUFF, she notes that a thesis statement "establishes a narrowed scope of your topic, provides at least one controlling idea or analytical purpose."
But you still might be questioning why a writer would put a thesis statement into his or her essay. You will note that in no way am I saying you would actually put a thesis statement in the essay. You should, however, know why you are writing the story and what you want the readers to leave with when they finish your novel. Marcie goes on to note that even in narrative writing, you would have a purpose to your story. In fact, the definition of narration in her book is a story that provides insight or truth gained from the experience.
Too often, writers just simply write, but without that controlling purpose or goal, the story ends up being pretty flat. This is very apparent when editors and agents discuss a prospective novel or read a submission from a new author. When the author just tells us the plot of the story and we are left with this question of "So what?" that is generally a story without a purpose.
Taking this a step further, we can see that having a thesis in your mind, both before you write the story and as you write it, will actually tie all of the events in your book together. It will give each scene your write and each passage of dialogue you have a meaning. The elements in your story should have some sort of meaning that advances the reader closer to that ultimate insight you want them at when they finish the book.
If we look at Jean Love-Cush's novel ENDANGERED we can see how the author has done just this. For those of you who are not familiar with this book, it is clearly one that needs to be read during these tough times here in the United States. Let me give you the "blurb" about the book from Amazon:
