Fiction literally means not true.However, a work of fiction can be said to embody truth.Explain how that works?

Fiction is like combining real-life and imagination. Some people write realistic fiction, which is fiction that really could happen, but they don't know if it has, the reason it's called fiction is because it comes from the writer's imagination. When you read a fiction novel that couldn't happen, most of the time writers put much of themselves, their outside influences, ideas, and values into their work of fiction, maybe base characters after real people, and that is why fiction is said to embody truth. The introduction to Frankenstein by Karen Karbiener is a really good example.(I don't know if you could find it online, but it's in the Barnes and Noble Clics version of Frankenstein.)
