“Mathematicians call it “the arithmetic of congruences.” You can think of it as clock arithmetic. Temporarily replace the 12 on a clock face with 0. The 12 hours of the clock now read 0, 1, 2, 3, … up to 11. If the time is eight o’clock, and you add 9 hours, what do you get? Well, you get five o’clock. So in this arithmetic, 8 + 9 = 5; or, as mathematicians say, 8 + 9 ≡ 5 (mod 12), pronounced “eight plus nine is congruent to five, modulo twelve.”

“The ordinary modes of human thinking are magical, religious, social, and personal. We want our wishes to come true; we want the universe to care about us; we want the approval of those around us; we want to get even with that s.o.b. who insulted us at the last tribal council. For most people, wanting to know the cold truth about the world is way, way down the list.”

“Nonmathematical people sometimes ask me, “You know math, huh? Tell me something I’ve always wondered, What is infinity divided by infinity?” I can only reply, “The words you just uttered do not make sense. That was not a mathematical sentence. You spoke of ‘infinity’ as if it were a number. It’s not. You may as well ask, 'What is truth divided by beauty?’ I have no clue. I only know how to divide numbers. ‘Infinity,’ ‘truth,’ ‘beauty’—those are not numbers.”

“What does the Right have to show for eight years of a Republican presidency? I supported George W. Bush in 2000 because I thought he had a conservative bone in his body somewhere. I supported him in 2004 because I thought him the lesser of two evils. At this point, I wouldn't let the fool park his car in my driveway. Bruce Bartlett was right, every damn word.”

“The job of conservatives is to keep the Republican Party driving on the right-hand side of the road. There are many ways we do this. We argue, we publish, we lobby, we campaign for conservative candidates. Another thing we do is, when the GOP goes off the rails on really key issues - size of government, the National Question, Wilsonian adventures - we stay home on election day.”

“Steve Sailer gives us the real Barack Obama, who turns out to be very, very different - and much more interesting - than the bland healer/uniter image stitched together out of whole cloth this past six years by Obama's packager, David Axelrod. Making heavy use of Obama's own writings, which he admires for their literary artistry, Sailer gives the deepest insights I have yet seen into Obama's lifelong obsession with 'race and inheritance,' and rounds off his brilliant character portrait with speculations on how Obama's personality might play out in the Presidency.”
