Suspension of disbelief

Suspension of disbelief is the avoidance—often described as willing—of critical thinking and logic in understanding something that is unreal or impossible in reality, such as something in a work of speculative fiction, in order to believe it for the sake of enjoying its narrative. Historically, the concept originates in the Greco-Roman principles of theatre, wherein the audience ignores the unreality of fiction to experience catharsis from the actions and experiences of characters.

The phrase was coined and elaborated upon by the English poet and philosopher Samuel Taylor Coleridge in his 1817 work Biographia Literaria: "that willing suspension of disbelief for the moment, which constitutes poetic faith".
