Chapter XIII

Of simple Modes; and first, of the simple Modes of Space.
Simple Modes.       §1. Though in the foregoing part, I have often mentioned simple
Ideas, which are truly the Materials of all our Knowledge; yet having
treated of them there, rather in the way that they come into the
Mind, than as distinguished from others more compounded, it will
not be, perhaps, amiss to take a view of some of them again under
this Consideration, and examine those different Modifications of the
same Idea; which the Mind either finds in things existing, or is able
— 167 —
to make within it self, without the help of any extrinsical Object, or
any foreign Suggestion.
      Those Modifications of any one simple Idea, (which, as has been said,
I call simple Modes ) are as perfectly different and distinct Ideas in the
Mind, as those of the greatest distance or contrariety. For the Idea
of Two, is as distinct from that of One, as Blueness from Heat, or either
of them from any Number: and yet it is made up only of that simple
Idea of an Unite repeated; and Repetitions of this kind joined to-
gether, make those distinct simple Modes, of a Dozen, a Gross, a Million.
