Irrationality is roughage in your diet

Irrationality is not the enemy of civilization, but is its closest friend..   Rationality is not the enemy, either, as those of postmodernist persuasion have been convinced.   The lack of any dialectical relationship between the two is the enemy of human, organic life.   Where one does not acknowledge and integrate the irrational parts of life, one runs the danger of ill health.   This is where shamanism differs from contemporary ways of thinking.   One cannot continue to make everything about life more efficient, more protected, more controlled, without running the risk of losing the very essence of what makes life meaningful.   Those aspects of life that are not anticipated, not devised for one's experience by a superior power, which involve possible danger or hardship, provide far more of the substance of life than managed and efficient thinking.

You can't protect life too much without destroying it.  One can eliminate certain hardships and it is rational to do so, but never deny yourself or others the chance to engage with aspects of life that you cannot control because they are unpredictable.

Too much refined sugar in one's diet leads to heart disease.   Too much containment and control leads to a diseased spirit. Humans were meant to run around and experience novelty, not be confined to a desk.
