Physicality refers to the physical dimension of human consciousness in the range physical-vital-mental. While every person has characteristics of all three levels, a person who is predominately physical in consciousness will exhibit more of the qualities of physicality.
Physicality implies unconsciousness, inertia, resistance to change, mindless, repetition, a refusal to learn from experience, an insistence on impulses even in the face of compelling reasons not to insist, and stubborness.
The mental is conscious, curious and willing to learn. The vital is expansive, eager for change and new experience. The physical is insistent and resistently unconscious.
