According to the Internet Encyclopedia of Philosophy, literary theory is "the body of ideas and methods we use in the practical reading of literature. By literary theory we refer not to the meaning of a work of literature but to the theories that reveal what literature can mean. Literary theory is a description of the underlying principles, one might say the tools, by which we attempt to understand literature. All literary interpretation draws on a basis in theory but can serve as a justification for very different kinds of critical activity."
