o receive them. Thus, light and colours come in
only by the eye, all kinds of noises by the ear, the tastes and smells
by the nose and palate. The most considerable of those belonging to the
touch are heat, cold, and solidity--which is the idea that belongs to
the body, whereby we conceive it to fill space.

Simple ideas of divers senses are the ideas of space or extension,
figure, rest, and motion, for these make perceivable impressions both
on the eyes and touch, and we can receive and convey into our minds the
ideas of the extension, figure, motion, and rest of bodies both by
seeing and feeling.

The mind, receiving the ideas mentioned in the foregoing from without,
when it turns its view inward upon itself and observes its own actions
about those ideas it has, takes from thence other ideas which are as
capable to be the objects of its contemplation as any of those it
received from foreign things. The two great and principal actions of the
mind which are most frequently considered, and which are so frequent
that everyone that pleases may take notice of them in himself, are these
two--Perception or Thinking, and Volition or Will. The power of thinking
is called the Understanding, and the power of volition is called the
Will. And these two powers, or abilities, in the mind are denominated
Faculties. Some of the modes of these simple ideas of reflection are
remembrance, discerning, reasoning, judging, knowledge, faith.

It has, further, pleased our wise Creator to annex to several objects
and to the ideas which we receive from them, as also to several of our
thoughts, a concomitant pleasure, and that in several objects to several
degrees, that those faculties which He has endowed us with might not
remain wholly idle and unemployed by us. Pain has the same efficacy and
use to set us on work that pleasure has, we being as ready to employ our
faculties to avoid that as to pursue this.

Existence and unity are two other ideas that are suggested to the
understanding by every object without and every idea within. Power,
also, is another of those simple ideas which we receive from sensation
and reflection; and, besides these, there is succession.

Nor let anyone think these too narrow bounds for the capacious mind of
man to expatiate in, which takes its flight farther than the stars and
cannot be confined by the limits of the world, that extends its
thoughts often even beyond the utmost expansion of matter and makes
