The thing that will put 99% of people in hospitals? Everybody can read eachothers mind. That is why it will take decades for the whole thruth to come out. It needs it be controlled or else 99% of people would commit suicide or murder.
The biggest part of it is body language and facial expressions. We dont need spoken language for expressing our thoughts and we never had. One of the things that spoken language is good for is lying.
Imagine that. That you find out one day everybody is able to read your mind and knew when you were lying or telling the thruth. That everybody knows your deepest secrects. All the good and all the bad that you did. How would you react to learn that thruth?
Thats why my philosophy is: dont think of something that you would not say to someones face. Because they already know subcounciously that you lie. Why they dont say anything to you is that most likely they also lie to themselves about it. Because a beautiful lie is easier to swallow then the hard thruth.
Be best to eachother. Be honest. It does not matter if the thing you say or do is good or bad. Good and bad are subjective and their meaning has changed drasticaly throughout history and will continue to change. The only thing that has stayed constant and always will be is honesty.
