Historical criticism seeks to interpret the work of literature through understanding the times and culture in which the work was written. The historical critic is more interested in the meaning that the literary work had for its own time than in the meaning the work might have today. For example, while some critics might interpret existential themes in Shakespeare's Hamlet, a historical critic would be more interested in analyzing the play within the context of Elizabethan revenge tragedy and Renaissance humor psychology.
Biographical criticism investigates the life of an author using primary texts, such as letters, diaries, and other documents, that might reveal the experiences, thoughts, and feelings that led to the creation of a literary work. For example, an investigation of Aldous Huxley's personal life reveals that Point Counterpoint is a roman a clef: the character Marc Rampion is a thinly disguised imaginative version of Huxley's friend, D.H. Lawrence.
Historical criticism and biographical criticism are used in tandem to explicate literary texts. Sometimes the very premise of a novel may seem more probable if the circumstances of composition are understood. For example, students often wonder why the boys in Lord of the Flies are oil the island. Their plane has crashed, but where was it going, and why? The book may be read as a survival adventure, but such a reading would not account for the most important themes. Knowing that William Golding was a British naval commander in World War II and knowing some of the facts of the British involvement in the war help in an understanding of the novel. The most important fact relating to the premise of the novel is that during the London Blitz (1940-1941) children were evacuated from the metropolitan area: some were sent to Scotland, some to Canada and Australia. Golding imagines a similar evacuation happening during his scenario of World War III. The itinerary of
