“Ever wonder if the opposite was true? That they were insane because of things they witnessed or were privy to?”
I think most humans have a natural “reality filter” that gives them a rosy tint on reality but also limits them in some way.
This is why many of the greatest artists/scientists/etc who gave us new perceptions on reality were depressed and/or “schizophrenic”. They can see things that a “normal” mind suppresses.
Such people are far more likely to medicate with powerful addictive drugs because the whole picture they see is difficult to handle.
The ones that can express what they see to average people and sell it are known as “artists”. The ones that can’t connect to others are called “crazy”.
I would wholly concur with that. Great perspective.
