Fiction is a form of literature that deals with informations or events that are not factuals but rather imaginary that was created from the imagination of the author.
- Fiction has three main elements that all writers should keep in mind:
- Setting or where the story takes place.
According to your definition of fiction, the accomplishments of fiction would be the creation of a manufactured/fictional "space" where things happen which are believable enough to function as a story that can be experienced as if it were real.
Believability is not a necessary element of good fiction, but it certainly helps in inspiring reader engagement.
A standard answer to this question is that fiction, like other forms of literature, imposes order on experience and thus helps us understand experience more clearly. (This is basically an Aristotelian answer.) Another answer is that fiction gives the writer opportunities to use language in memorable and indeed beautiful ways, thus showing the potential power of language.
Fiction accomplishes many things that are not always possible with other forms of writing. For one thing, fiction lets the reader escape into a world that doesn't really exist. Readers can find an escape from reality in the fantasy world of the author. Readers can also learn and explore concepts or ideals that might be rejected when viewed through a non-fiction piece. Fiction also allows the writer a lot of freedom. The author is not bound by anything other than the elements of the story itself. The author does not have to research facts or stick to histories. They can write whatever they want to write. Anything can exist and anything can happen in fiction. The level of freedom achieved through fiction writing is difficult to accomplish with other forms of writing.
