Technical knowledge, divorced from what it is supposed to be knowledge of, yields only the illusion of understanding. It's like being able to reel off the locations in a baseball field -- first base, second base, third base, home plate, left field, right field, center field, pitcher's mound -- without having the slightest clue as to how they function in a game. You can talk the talk, but you can't walk the walk.
