New Criticism was a literary theory that emphasized close reading of texts and considered works of literature as self-contained artifacts rather than as expressions of external biographical or historical contexts. It dominated American literary criticism between 1940-1960. New Critics believed the meaning of a text came from analyzing its formal elements like symbols, metaphors, and literary devices rather than the author's intentions or a reader's subjective response. They advocated an objective interpretation based solely on what was contained within the text itself.
