Energy with Negative Entropy is perhaps the most positive thing in the universe, so we decided it needed a positive name.
We took the international unit of energy, the erg (derived from the Greek word for work, ergon), and added a zero to it, inspired by the fundamental energy state E0.
Erg0 led us to a play on words with Descartes' Ergo.
The theomorphic variation Ergod looked to be useful philosophically.
But the powerful adjective Ergodic puts us squarely in conflict with an existing term in statistical physics. We feel it's not the first time that a word takes on an entirely new meaning in a closely related field. See our justification.
Ergodic processes are those that resist the terrible and universal Second Law of Thermodynamics, which commands the increase of chaos and entropy (disorder).
Without violating that inviolable law overall, they reduce the entropy locally, bringing pockets of cosmos and negative entropy (order and information-rich structures).
We call all this cosmic order the Ergo. It is the ultimate sine qua non.
