A well considered and nicely written article. I’m not sure if it’s intended as a persuasive piece, or quasi instructional. There is a single “defining characteristic”, universal to all people I feel could have been touched on directly. Human Nature (fallibilities and all) is where our collective and individual best and worst potentials share a room with habits, fears and/or an irrational desire to escape. Even when there’s no compelling requirement to do so. The human nature floorshow is always colorful, but not always pretty. I perceive human nature to be where individual predictability can to some extent be observed and perceived by others.
