Believing Bullshit: How Not to Get Sucked into an Intellectual Black Hole

A philosophy professor at the University of London, Law describes eight "intellectual black holes," traps that seem to lend credence to scientifically or rationally incorrect propositions. Recognizing such black holes as "playing the mystery card" (e.g., arguing that science can tell us whether ghosts exist) will help readers identify and critique illogical arguments. One particularly interesting concept is the "blunderbuss," which cites real but irrelevant illogical elements of, say, certain New Age beliefs. Another concept is what philosopher Daniel Dennett once called a "deepity," which Law defines as "saying something with two meanings"—one true but trivial, the other false but seemingly profound. Law shows how these and other verbal sleights of hand are used in a wide variety of belief systems, including the paranormal, homeopathy, Christian Science, and belief in UFOs. Law includes an entertaining appendix of fictional letters called, pace C.S. Lewis, the "Tapescrew Letters," which recapitulate his eight logical black holes. Though he writes clearly and persuasively, this is not a particularly easy read, but his subject is important and deserving of readers' attention. Illus. (Apr.)
