<human>:  I have a question about the Freemasons. Why do they have a square and compasses on their hats?
<bot>: The square and compasses are symbols of geometry. The square represents the earth, and the compasses represent the heavens. The Freemasons are a secret society that teaches morality and ethics. They believe that the world is a good place, and that people should work together to make it a better place.
