Let the Bible be the Bible! It’s not about science. It’s not accurate history. It is a grab bag of religious fantasies written by many authors. Some of its myths, like the Star of Bethlehem, are very beautiful. Others are dull and ugly. Some express lofty ideals, such as the parables of Jesus. Others are morally disgusting.

Public infatuation with alternative medicines of all varieties shows no sign of abating. Acupuncture, homeopathy, aromatherapy, herbal remedies, chelation, iridology, therapeutic touch, magnet therapy, psychic healing, and so on are gaining new converts every day. The tragedies occur, of course, when gullible sufferers rely solely on such remedies and avoid seeking mainstream help. It would be good if we had some statistical evidence about the frequency of deaths following reliance on pseudomedicines.

I've never made a discovery myself, unless by accident. If you write glibly, you fool people. When I first met Asimov, I asked him if he was a professor at Boston University. He said no and … asked me where I got my Ph.D. I said I didn't have one and he looked startled. "You mean you're in the same racket I am," he said, "you just read books by the professors and rewrite them?" That's really what I do.

Carlos Castaneda died in Westwood, California, in 1998. “His only real sorcery,” writes Kathryn Lindskoog in her entertaining book Fakes, Frauds, and Other Malarkey (1993), “was turning the University of California into an ass.” The next time you come close to a crow, try calling out “Hello Carlos!” If you are high enough on peyote, you might hear the bird answer.

Debunking bad science should be constant obligation of the science community, even if it takes time away from serious research or seems to be a losing battle. One takes comfort from the fact there is no Gresham's laws in science. In the long run, good science drives out bad.

Biographical history, as taught in our public schools, is still largely a history of boneheads: ridiculous kings and queens, paranoid political leaders, compulsive voyagers, ignorant generals — the flotsam and jetsam of historical currents. The men who radically altered history, the great scientists and mathematicians, are seldom mentioned, if at all.

The curious notion that “truth” does not mean “correspondence with reality,” but nothing more than the successful passing of tests for truth, was dealt a death blow by Alfred Tarski’s famous semantic definition of truth: “snow is white” is true if and only if snow is white. The definition goes back to Aristotle. Most philosophers of the past, all scientists, and all ordinary people accept this definition of what they mean when they say some thing is true. It is denied only by a small minority of pragmatists who still buy John Dewey’s obsolete epistemology.

Suppose, however, there is not enough time for measures to be taken to prevent a collision, and earth is shattered by a giant NEO that will hurt us all into oblivion. What are the philosophical implications of such an event? This obviously is not a problem for atheists, agnostics, or pantheists because they are resigned to the fact that nature does not care a rap about preserving a species.
What about theists? I’m inclined to think that even to them a certain extinction of humanity would be acceptable. The Biblical Jehovah, remember, is said to have drowned every man, woman, baby, and their pets, except for Noah and his family.
If God can allow an earthquake to kill thousands, or the Black Death to wipe out half of Europe, surely she would have no scruples about allowing an asteroid to bring human history to a flaming end.

My attack on Freud brought a raft of angry letters from dedicated Freudians. One reader assured me that Freudianism is “alive and well.” True, but alive and well only among a dwindling remnant of Freud acolytes, not among the majority of today’s psychiatrists or intellectuals.

Ever since I was a boy, I've been fascinated by crazy science and such things as perpetual motion machines and logical paradoxes. I've always enjoyed keeping up with those ideas. I suppose I didn't get into it seriously until I wrote my first book, Fads and Fallacies in the Name of Science. I was influenced by the Dianetics movement, now called Scientology, which was then promoted by John Campbell in Astounding Science Fiction. I was astonished at how rapidly the thing had become a cult.
