The truth and the facts aren't necessarily the same thing. Telling the truth is the object of all art; facts are what the unimaginative have instead of ideas.
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.
If the world were to end tomorrow and we could choose to save only one thing as the explanation and memorial to who we were, then we couldn't do better than the Natural History Museum, although it wouldn't contain a single human. The systematic Linnean order, the vast inquisitiveness and range of collated knowledge and beauty would tell all that is the best of us.
