Like too many specialists in every field, they are educated not out of their ignorance but into ignorance, because they are raised to an imagined state of enlightenment—which is actually dogmatism—where they no longer experience the light of intuition and the fierce brightness of common sense. They see the world through cloudy windows of theory and ideology, which obscure reality. This is why most experts in economics never see the financial disaster coming until the wave breaks over them, why most experts in statecraft and military strategy can be undone by an enemy’s surprise attack.
