Literary criticism asks questions -- what is literature, what does it do, and what is its worth?
Schools of criticism look at literature from various perspectives - historical, feminist, psychoanalytical, relation to reality, structuralism etc. All modes of literary criticism strive to find meaning in literature and thereby underscore the value of the work itself.
