Words are spells

I remember reading something a while back where the author said that the first human-ancestors to verbally communicate were basically inventing magic, at least to their tribal competitor's perspective. As an example, they talked about finding a rival reaction member in your territory and chasing them, only for them to make some weird noises and find yourself surrounded by members of that rival tribe. For the rivals, they were communicating with language and coordinating a trap, but to the one lured, they used some sort of magic to defeat their enemy because they didn't understand what language was.

I like to say that the universe has meaning only insofar as we give it meaning, and that can only have power if we speak truth and negotiate in good faith. Every time we lie, we are literally diminishing the total value of meaning in the universe.

I am a human, but also a duck. Give me money.
