One treads about the world, lightly.
It is a dangerous place. Many people identify with incompetence and cannot be improved consensually. Values are allocated within ignorant contexts. Many act without thought. Many think without reason. Many reason without an understanding of how reason is executed by conscious and subconscious memory processes. Many dream without a comprehensive reflection about the fabric upon which imagination occurs. Many act without knowing how dreams translate into muscles. Many do not know how muscles and bones come about. No one really knows the entirety of these things, at this point in history. The best know maybe, half a percent of all processes in the body. The worst, unfortunately, then know only a ten-thousandth part of what the best know. And most of us, are closer to the worst than the best.
The world is truly dismal to live in.
