We thought putting wisdom in short, memorable chunks was a good idea
We called them "proverbs" and found them satisfying to repeat
All cultures have them, many of us have had this same good idea in different times and places
Some of transparent and obvious, others are mysterious, opaque to an outsider
If space aliens had proverbs, we wouldn't understand them
Or maybe we would, the way we understand this one from Spain:
"If the jug hits the rock, it's bad for the jug
And if the rock hits the jug, it's bad for the jug."
