Mario Vargas Llosa

[A]ll fictions make their readers live “the impossible,” taking them out of themselves, breaking down barriers, and making them share, by identifying with the characters of the illusion, a life that is richer, more intense, or more abject and violent, or simply different from the one that they are confined to by the high-security prison that is real life. Fictions exist because of this fact. Because we have only one life, and our desires and fantasies demand a thousand lives. Because the abyss between what we are and what we would like to be has to be bridged somehow. That was why fictions were born: so that, through living this vicarious, transient, precarious, but also passionate and fascinating life that fiction transports us to, we can incorporate the impossible into the possible and our existence can be both reality and unreality, history and fable, concrete life and marvellous adventure.
