I.A. Richards was an influential 20th century British literary critic who helped pioneer New Criticism. He emphasized close textual analysis and believed criticism should be empirical and focus solely on what is in the text rather than external factors. Richards developed techniques for analyzing how words, metaphors, rhythm and context contribute to a work's meaning and emotional effects. He also explored literature's psychological impacts and believed it could provide readers with emotional balance and organization. Richards' works and experiments analyzing anonymous poems without context helped establish Practical Criticism as a new approach to literary study.
