"adical Islam is heir, above all, to Nazism. The destruction of the World Trade Center was meant not only to wreak terror. Like the smashing of the Bamiyan Buddhas, it was meant to obliterate greatness and beauty, elegance and grace. These artifacts represented civilization embodied in stone or steel. They had to be destroyed. This worship of death and destruction is a nihilism of a ferocity unlike any since the Nazis burned books, then art, then whole peoples. Goebbels would have marvelled at the recruitment tape for al Qaeda, a two-hour orgy of blood and death: image after image of brutalized Muslims shown in various poses of victimization, followed by glorious images of desecration of the infidel-mutilated American soldiers in Somalia, the destruction of the USS Cole, mangled bodies at the American embassies in Kenya and Tanzania."

“Courage is not a quality one normally associates with mathematicians. Yet it should apply to people who work in their attics in secret for seven years without cease on a problem that has eluded the greatest mathematical minds since first proposed in 1637.”

“Affluent enviros are all for wind farms, until one is proposed that might mar the serenity of a sail from the crew-necked precincts near Nantucket Sound. Then it's clean energy for thee, not for me.”

“In explaining any puzzling Washington phenomenon, always choose stupidity over conspiracy, incompetence over cunning. Anything else gives them too much credit.”
