Aristotle described a slightly mysterious state of human experience called eudaimonia. The prescise translation of this word is subject to debate. Some say human flourishing, some say good humors, some say high spirits, but I like “having good demons”.
I imagine the source as a light that feeds certain root concepts of reality. Things like geometry and logic form a layer of reality that feeds more complex systems the way that alge and plants, the producer type of organism, feed the chemistry of consumer organisms such as animals.
One way to imagine a demon is as an organism that creates its own food. A fire demon doesn’t exactly survive by consuming fuel. It is sustained by increasing the amount of fire in its sphere of influence. The potential energy of a demon is increased as it expends kinetic energy. These seemingly infinite beings are limited by the other conceptual agents who compete for a rescource that could be described as concepual space.
Eudaimonia is when you’ve got a positive feedback loop going with a conceptual agent, and the two (or more) of you are humming along helping each other out. People can sense when this is happening and we can tell that it helps us survive.
What is a demon?
