Mencken: "People constantly speak of 'the government' doing this or that, as they might speak of God doing it. But the government is really nothing but a group of men, and usually they are very inferior men."

Kaczynski: "It is obvious that [leftists] are not cool-headed logicians systematically analyzing the foundations of knowledge. They are deeply involved emotionally in their attack on truth and reality."
