Self-Censorship Rampant: Playwright Arthur Miller says America’s artists are censoring their own works for the sake of government grants. Such self-censorship allows freedom to be “killed without a trace,” Miller said Sunday at a daylong humanities festival called “Expressions of Freedom,” sponsored by the Illinois Humanities Council. Miller, 75, whose works include the plays “Death of a Salesman” and “The Crucible,” said the First Amendment is the artist’s ultimate weapon against censorship.
