Power includes Relation.       §3. I confess Power includes in it some kind of relation, (a relation to
Action or Change,) as indeed which of our Ideas, of what kind so-
ever, when attentively considered, does not? For our Ideas of Exten-
sion, Duration, and Number, do they not all contain in them a
secret relation of the Parts? Figure and Motion have something
relative in them much more visibly: And sensible Qualities, as
Colours and Smells, etc. what are they but the Powers of different
Bodies, in relation to our Perception, etc. And if considered in the
things themselves, do they not depend on the Bulk, Figure, Texture,
and Motion of the Parts? All which include some kind of relation in
them. Our Idea therefore of Power, I think, may well have a place
amongst other simple Ideas, and be considered as one of them, being
one of those, that make a principal Ingredient in our complex Ideas
of Substances, as we shall hereafter have occasion to observe.
