And this is the second problem with plagiarism. It is not merely extremist. It has also become disconnected from the broader question of what does and does not inhibit creativity. We accept the right of one writer to engage in a full-scale knockoff of another—think how many serial-killer novels have been cloned from "The Silence of the Lambs." Yet, when Kathy Acker incorporated parts of a Harold Robbins sex scene verbatim in a satiric novel, she was denounced as a plagiarist (and threatened with a lawsuit).
