The human mind suffers from three ailments as it comes into contact with history, what I call the triplet of opacity:
illusion of understanding
the world that is more complicated (or random) than they realize;
retrospective distortion
how we can assess matters only after the fact, as if they were in a rearview mirror
history seems clearer and more organized in history books than in empirical reality
overvaluation of facts
and the handicap of authoritative and learned people, particularly when they create categories—when they “Platonify.”
