In a traditional manner criticism still covers exegesis, evaluation and interpretation but it is now stretching its range over theory. Whether you consider theory as a discussion or debates on the basis of certain definition, as the search for necessary and sufficient values for critical practice, or consider theory as a process for making social, historical or ideological pre-suppositions. No matter which option you chose, it will be hard to figure out a clear boundary between theory and criticism. However, they stumble into each other on various situations.
