The Strange Case of Dr. Jekyll and Mr. Hyde talks about the <em>duality of human nature</em>. What is Duality? It's a philosophical theory that the world can be divided in two basic entities.<u> In the novel it's good versus evil</u>. As we go through the novel, we realize that humans have both good and evil and one without the other can't exist.
Dr. Jekyll has a socially accepted behavior, but he also wants to do things he has been told all his life not to do. That's why he creates Mr. Hyde, and in a way he releases all his demons. Mr. Hyde takes joy in being evil and doing bad things. But soon Dr. Jekyll realizes that <em>good and bad balance each other, </em>as evil starts to take over.
Basically, the novel talks about the good and evil that exits in every person. We need both to have a balanced life.
