Many things cannot be understood. Either because they are beyond
our comprehension or we see a pattern to things that doesn’t exist or is merely coincidental. However, human beings must live in frames of meaning to stay mentally strong and physically well.
As such, our propensity for reading meaning into things, finding the key for that imaginary lock, can make a gull of us. But do otherwise is to risk personal crisis, and as "meaning structures" are scaffolds to build individual and societal achievements. Unfortunately, they can also serve as a hanging platform when their bottoms give out!
