In this paper I challenge the opinion that literary theory should not be taught at upper secondary level. According to French literary theorist Tzvetan Todorov, the teacher at this level should aim at teaching literary works, not theory. Theory should only be used as an invisible instrument. My hypothesis is that literary theory can be used successfully at upper secondary level. A certain insight in theory can help the pupils become better readers. A possible way to do this is by using an inductive approach, that is starting with examples from literary works and get to the theory instead of the other way.
