Walter Benjiman on how the novel killed the oral tradition of the story:
"The earliest symptom of a process whose end is the decline of storytelling is the rise of the novel at the beginning of modern times.
What distinguishes the novel from the story … is its essential dependence on the book. The dissemination of the novel became possible only with the invention of printing. What can be handed on orally, the wealth of the epic, is of a different kind from what constitutes the stock in trade of the novel.
What differentiates the novel from all other forms of prose literature — the fairy tale, the legend, even the novella — is that it neither comes from oral tradition nor goes into it. This distinguishes it from storytelling in particular. The storyteller takes what he tells from experience — his own or that reported by others. And he in turn makes it the experience of those who are listening to his tale.
The novelist has isolated himself. The birthplace of the novel is the solitary individual, who is no longer able to express himself by giving examples of his most important concerns, is himself uncounseled, and cannot counsel others. To write a novel means to carry the incommensurable to extremes in the representation of human life. In the midst of life’s fullness, and through the representation of this fullness, the novel gives evidence of the profound perplexity of the living."
