Literature was born not the day when a boy crying wolf, wolf came running out of the Neanderthal valley with a big gray wolf at his heels: literature was born on the day when a boy came crying wolf, wolf and there was no wolf behind him. That the poor little fellow because he lied too often was finally eaten up by a real beast is quite incidental. But here is what is important. Between the wolf in the tall grass and the wolf in the tall story there is a shimmering go-between. That go-between, that prism, is the art of literature.
From Lectures on Literature (1980) by Russian author Vladimir Nabokov (1899-1977), best known for his novels Speak, Memory (1951), Lolita (1955), and Pale Fire (1962).
