the irrationality of Bill Maher

Looks like the main star of Religulous isn't all that "rational" himself.

On Oct. 3, Mr. Maher debuts "Religulous," his documentary that attacks religious belief. He talks to Hasidic scholars, Jews for Jesus, Muslims, polygamists, Satanists, creationists, and even Rael -- prophet of the Raelians -- before telling viewers: "The plain fact is religion must die for man to live."

But it turns out that the late-night comic is no icon of rationality himself. In fact, he is a fervent advocate of pseudoscience. The night before his performance on Conan O'Brien, Mr. Maher told David Letterman -- a quintuple bypass survivor -- to stop taking the pills that his doctor had prescribed for him. He proudly stated that he didn't accept Western medicine. On his HBO show in 2005, Mr. Maher said: "I don't believe in vaccination. . . . Another theory that I think is flawed, that we go by the Louis Pasteur [germ] theory." He has told CNN's Larry King that he won't take aspirin because he believes it is lethal and that he doesn't even believe the Salk vaccine eradicated polio.

Anti-religionists such as Mr. Maher bring to mind the assertion of G.K. Chesterton's Father Brown character that all atheists, secularists, humanists and rationalists are susceptible to superstition: "It's the first effect of not believing in God that you lose your common sense, and can't see things as they are."
