"What is fiction? And how does reading fiction affect how we experience the world?
The literary historian Luiz Costa Lima has argued that prior to the invention of fiction, narratives were largely measured against one overriding standard: the perceived truthfulness of their relation to the world. That truth was often a moral or theological one, and to the extent that narratives related the deeds of men, proximity to an image of virtue or holiness would be considered worthy of imitation, and distance from it worthy of opprobrium.
Fiction is different.
For a prose narrative to be fictional it must be written for a reader who knows it is untrue and yet treats it for a time as if it were true. The reader knows, in other words, not to apply the traditional measure of truthfulness for judging a narrative; he or she suspends that judgment for a time, in a move that Samuel Taylor Coleridge popularized as “the willing suspension of disbelief,” or “poetic faith.” Another way of putting this is to say that a reader must be able to occupy two opposed identities simultaneously: a naïve reader who believes what he is being told, and a savvy one who knows it is untrue.

The fictional worldview, then, is one in which we are able to divide our selves to assume simultaneously opposing consciousnesses, and to enter and leave different realities at will, all the while voluntarily suspending judgments concerning their relation to an ultimate reality. This worldview has had an extraordinarily powerful impact on the modern world; in some interpretations it is the very epistemological signature of modernity, affecting equally our thought and politics as thoroughly as it does our art and literature.

As Cervantes realized in the context of the newly born mass culture of the Catholic, imperial, Spanish state, irony expertly wielded is the best defense against the manipulation of truth by the media. Its effect was and still is to remind its audience that we are all active participants in the creation and support of a fictional world that is always in danger of being sold to us as reality."
