Science fiction allows us to encounter uncomfortable subjects through metaphor. Metaphor: a symbol or idea that stands in for something else. Sometimes these are quick comparisons; sometimes the metaphor is extended throughout a piece of writing. Ex. comparisons: “That man is a tomcat.” “This situation is a timebomb.” Ex. extended : Mars Attacks Mixed metaphors are signs of poor writing. Ex: “I put down roots and spread my wings.” “Checkmate! Touchdown! The eagle has landed!” Allegory: an entire story that exists as a metaphor Ex.: 1984, Animal Farm, Narnia
