It's a great historical joke that when the Spanish met the Aztecs, it was a blind date made in serve-you-right heaven. At the time, they were the two most unpleasant cultures in the entire world, and richly deserved each other. Still, the story of how stout Cortes blustered, bullied and bludgeoned his way to collapsing an entire empire with a handful of contagious hoodlums is astonishing.
History is, and has always been trameled by facts. It may ignore some and deny others; but it cannot accommodate itself unreservedly to theories; it cannot be stripped of things evidenced in favor of things surmised.
The subject of history is the life of peoples and of humanity. To catch and pin down in words--that is, to describe directly the life, not only of humanity, but even of a single people, appears to be impossible.
