The New Left: The Anti-Industrial Revolution is a 1971 collection of essays by the philosopher Ayn Rand, in which the author argues that religion, the New Left, and similar forces are irrational and harmful. A revised edition appeared in 1975, and an expanded edition edited by Peter Schwartz was published in 1999 under the title Return of the Primitive: The Anti-Industrial Revolution. Most of the essays originally appeared in The Objectivist.
