. . . A convincing impossibility in mimesis is always preferable to an unconvincing possibility. The burden is instantly placed not on simple verisimilitude or reference . . . but on mimetic persuasion: it is the artist’s task to convince us that this could have happened. Internal consistency and plausibility then become more important than referential rectitude. And this task will of course involve much fictive artifice and not mere reportage.
