In my Critical Responses to Poetry course, we were discussing theories of identity in literature, and how literature not only expresses/records the world around us, but consciously shapes it by the very act of description. That is, people read these works and then imitate them, making a second-hand version of life into a performance of life itself. In Chapter 8 of his book, Literary Theory: A Very Short Introduction, he writes,
“Literature has not only made identity a theme; it has played a significant role in the construction of the identity of readers...Literary works encourage identification with characters by showing things from their point of view. Poems and novels address us in ways that demand identification, and identification works to create identity; we become who we are by identifying with figures we read about” (113).
