Kurt Vonnegut on the conventions found in plots

From David Hayman, David Michaelis, George Plimpton, & Richard Rhodes’s interview of Kurt Vonnegut in “The Art of Fiction No. 64” (The Paris Review: Spring 1977, No. 69):

INTERVIEWER Let’s talk about the women in your books.

VONNEGUT There aren’t any. No real women, no love.

INTERVIEWER Is this worth expounding upon?

VONNEGUT It’s a mechanical problem. So much of what happens in storytelling is mechanical, has to do with the technical problems of how to make a story work. Cowboy stories and policeman stories end in shoot-outs, for example, because shoot-outs are the most reliable mechanisms for making such stories end. There is nothing like death to say what is always such an artificial thing to say: “The end.” I try to keep deep love out of my stories because, once that particular subject comes up, it is almost impossible to talk about anything else. Readers don’t want to hear about anything else. They go gaga about love. If a lover in a story wins his true love, that’s the end of the tale, even if World War III is about to begin, and the sky is black with flying saucers.
