A metaphor is a literary figure of speech that describes a subject by asserting that it is, on some point of comparison, the same as another otherwise unrelated object. Metaphor is a type of analogy and is closely related to other rhetorical figures of speech that achieve their effects via association, comparison or resemblance including allegory, hyperbole, and simile.

One of the most prominent examples of a metaphor in English literature is the All the world's a stage monologue from As You Like It:

This quote is a metaphor because the world is not literally a stage. By figuratively asserting that the world is a stage, Shakespeare uses the points of comparison between the world and a stage to convey an understanding about how the world works and the lives of the people within it.

The Philosophy of Rhetoric (1936), by I. A. Richards describes a metaphor as having two parts: the tenor and the vehicle. The tenor is the subject to which attributes are ascribed. The vehicle is the object whose attributes are borrowed. In the previous example, "the world" is compared to a stage, describing it with the attributes of “the stage”; "the world" is the tenor, and "a stage" is the vehicle; "men and women" is a secondary tenor, "players" is the secondary vehicle.

Jane Hirshfield (born 24 February 1953) is an American poet.

Jane Hirshfield was born in New York City and received her bachelor's degree from Princeton University in the school's first graduating class to include women. She later studied at the San Francisco Zen Center, including three years of monastic practice at Tassajara Zen Mountain Center. She received lay ordination in Soto Zen in 1979.

Hirshfield has worked as a freelance writer, editor, and translator. Her seven books of poetry have each received numerous awards. Her fifth book, Given Sugar, Given Salt, was a finalist for the National Book Critics Circle Award and her sixth collection, After, was shortlisted for the T.S. Eliot Prize (UK) and named a "best book of 2006" by The Washington Post, The San Francisco Chronicle, and the Financial Times. She has written a book of essays, Nine Gates: Entering the Mind of Poetry. The Ink Dark Moon, her co-translation of the work of the two foremost women poets of classical-era Japan, was instrumental in bringing tanka (a 31-syllable Japanese poetic form predating the better known haiku) to the attention of American poets. She has three edited books collecting the work of women poets.

George P. Lakoff ( /ˈleɪkɒf/, born May 24, 1941) is an American cognitive linguist and professor of linguistics at the University of California, Berkeley, where he has taught since 1972. Although some of his research involves questions traditionally pursued by linguists, such as the conditions under which a certain linguistic construction is grammatically viable, he is most famous for his ideas about the centrality of metaphor to human thinking, political behavior and society. He is particularly famous for his concept of the "embodied mind", which he has written about in relation to mathematics. In recent years he has applied his work to the realm of politics, exploring this in his books. He is a member of the scientific committee of the Fundacion IDEAS, Spain's Socialist Party's think tank. He was the founder of the now defunct progressive think tank the Rockridge Institute.

Lakoff began his career as a student and later a teacher of the theory of transformational grammar developed by Massachusetts Institute of Technology professor Noam Chomsky. In the late 1960s, however, he joined with others to promote generative semantics as an alternative to Chomsky's generative syntax. In an interview he stated:
