Some highlights: despite being so "brilliant", Scalia was unsure about the pronunciation of the word "ukase" and wasn't familiar with the term "tell" as applied to poker. I am neither a lawyer nor a poker player, but I knew both of these. And I'm not particularly bright.
Scalia also knew nothing about linguistics, if he thought "Words have meaning. And their meaning doesn’t change." That's an extremely naive view of language and meaning. In reality, the meaning of words is fuzzy and smooshed out. And meaning changes all the time. Compare our current understanding of "nubile" with the dictionary definition from a dictionary 50 years ago.
Scalia read the Wall Street Journal and the Moonie-controlled Washington Times, but stopped reading the Washington Post because it was "slanted and often nasty". He didn't read the New York Times at all. Talk about being unaware of your own biases!
Scalia believed that the "Devil" is a real person because it is Catholic dogma (and by implication, because one cannot be a Catholic without accepting all of Catholic dogma). That's exactly the kind of black-and-white extremist viewpoint it takes to be an originalist. He thought this being was occupied in getting people not to believe in the Christian god. And he liked The Screwtape Letters, easily the stupidest of C. S. Lewis's output (and that's saying something). Scalia justified his belief by saying "Many more intelligent people than you or me have believed in the Devil." Yeah, well, many more intelligent people than I believe in Scientology, Bigfoot, and alien abductions, but that isn't a good argument for them. He also said that the Devil's becoming cleverer was "the explanation for why there’s not demonic possession all over the place. That always puzzled me. What happened to the Devil, you know? He used to be all over the place." The other explanation -- that there is no Devil and demonic possession never happened (it was health conditions misinterpreted by an ignorant and superstitious populace) -- was too obviously correct for him to consider.
Scalia thought that the only two possible choices after his death were "I'll either be sublimely happy or terribly unhappy." The obvious correct choice -- namely that he would simply cease to be -- did not even enter his mind as a possibility.
Scalia thought he was "heroic" by not recusing himself in a case where he clearly should have recused himself.
Reading this interview I could only think: What an asshole! Good riddance.
