The word criticism is derived from Greek word meaning ‘Judgement’. It is an exercise in judgement. Literary criticism is the exercise of judgment on works of literature. To examine the excellences and defect and finally to evaluate the artistic worth is the function of criticism. It is not as simple as it appears because we have a host of conflicting views, theories and definitions. Cause of such diversity bring out the complexity of nature of criticism. Critics vary in their attitude, intellectual pre-occupation, prejudices and predilections. A critic with religious beliefs and a set of ethical values will hold a view consistent with his aesthetic appreciation.

Theory of criticism is also closely connected with the theory of poetry. This in turn is connected with the spirit of the age.
