In nature it is typically the clumsy ones without much skill or fine character who get eaten away. It is the ones with stupid thoughts and not much wisdom of life. Itis the ones who do not live in the moment but think, doze or are with dizzy attention. It is the ones without much social wisdom.
The nature teaches tactics, the beauty of nature does this. The nature is a multitude of shapes with enermous variation from slight tones and small differencies to entirely different kinds of plants and animals.
So the nature teaches a sense of structures which is good for thinking and social skills. One needs to learn to see more structures at a time, understand them, not to miss anything and not to misinterprete anything, observe them also with the sense of atmospheres and turn that into social wisdom.
Trees in a not so tense forest teach one social skills> I live like this and so do the others and like this forest view, we form a natural harmony, each one living one's own life and the distance to others giving room to full life in harmony with others.
The animal who sees deeper, can predict the behaviour of others - either escaping if one is prey oneself, or catching prey if one is a predator.
Much of the stupidity of animals comes from the same source as the stupidity of humans: watching the simplicity of straight lines and boxes instead of the complexity of the nature views.
The more simple is more clumsy and so end up in a social fight more often. The wise is often good natured and llent in survival skills.
