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.[1] 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.[2]
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".[3]
