@spreadingthegoodword,
Even though we may never be able to perfectly prove the Law of Emotional Balance because quantifying all emotions, a person will experience in their lifetime, is impossible, that does not mean that we can't build an extremely strong case to support emotional balance as a law. Even without a way of quantifying all emotions we can still determine if the Law of Emotional Balance is still a possibility or not. In the book Of Grandeur: The Law of Emotional Balance, falsifiable experiments have been added to build a case in support of emotional balance as a law. The fact also remains that in order for the Law of Emotional Balance to be true, certain base requirements would have to be met. The universe would need to have uncertainty programmed into it because without uncertainty, we could predict the future and take in only happiness and no sadness and violate the Law of Emotional Balance. We would need to have dreams where people's defenses are dropped so they could be forced to experience specific emotions to prevent the Law of Emotional Balance from being violated. We would need physiological balance in cells "Homeostasis" because cells are also living organisms that comprise other organisms like humans. We would need unusual/unique cultural structures with flexibility "Sins/penance/religion, laws, punishments, government...... The list goes on... The fact remains that all of the base requirements for the Law of Emotional Balance are in place so why not try to test to see if emotional balance is maintained by a law... Conservation laws prevent charged particles from turning back into pure energy until they are neutral. Emotions and electricity may very well be directly tied together so it is not a too much of a stretch, to say that there is a conservation law that governs emotions. There may very well be a reservoir of emotional energy and this reservoir is forced to follow the Law of Emotional Balance and is what humans have come to worship as God.
