In history you read about elves, fairies, little people, spirits. It was an accepted part of reality.
But now that’s obvious nonsense and if you see fairies then you need a doctor.
Are we insane now?
Yes I know, nutrition, literacy and the scientific enlightenment. But still.
Ah, so when we scrape off the wit it is just an accusation of insanity.
You conform closely to the conventions of the hour. Like a fungus to the bark of a tree.
