I have to disagree. I see there being four sources of power, with some small degree of overlap.
You have the power of society, which incorporates money, status, and structure.
You also have the power of the mind, which includes experience, intelligence, education, and wisdom.
There is also physical power, which stems from our bodies in terms of strength, speed, and fortitude.
Lastly, there is the power of spirit, which cannot be measured or defined by science, and usually the purview of the gods, spirits, or supernatural forces.
