A rational, physical, objective view of life requires the common senses of sight, hearing, taste, smell & touch.
To a spiritually unaware person, common sense is what is common knowledge to everyone. It is what normally happens according to what is believed to be normal behaviour and is the normal effect that is experienced by what is being caused to happen.
Common sense requires an unemotional view of life. Irrational and emotional behaviour are considered to lack common sense.
An awakened spiritual perspective of life uses the common senses of intuitively seeing, feeling and knowing.
A spiritually aware person knows that nothing is normal, everything is continually changing, and a belief in faith allows miracles to happen. Metaphysics and the paranormal make sense.
To a non-spiritual person, intuition is not a common sense. What is not common sense is seen as nonsense because their common sense determines it to be so.
Common sense is a subjective perspective of life dependent on what senses, physical and spiritual, are commonly being used by an individual.
The irony is that emotion, intuition and sensitivity are not common sense to most people.
