In which, and the like cases, the power we consider is in reference to the change of perceivable ideas. Power, active and passive. Power thus considered is two-fold, viz. The one may be called active, and the other passive power.

Power includes relation.
Figure and motion have something relative in them much more visibly. All which include some kind of relation in them. The clearest idea of active power had from spirit. We are abundantly furnished with the idea of passive power by almost all sorts of sensible things. In most of them we cannot avoid observing their sensible qualities, nay, their very substances, to be in a continual flux.
