By that definition, though, what power produced by human beings isn't internal power? Isn't that just another way of saying "the power we produce"?
We can do the philosophy 101 argument exercise, do we really produce anything?
Human beings don't have power, thinking so is an illusion. Having power is a human ego trip of thinking you are in control. We are all controlled by nature and it's laws. We work nature's biding. If we truely had power our world and the natural world would be vastly different. We would be vastly different.
