th, or eighth sense
can possibly be;--which, whether yet some other creatures, in some other
parts of this vast and stupendous universe, may not have, will be a
great presumption to deny. He that will not set himself proudly at the
top of all things, but will consider the immensity of this fabric, and
the great variety that is to be found in this little and inconsiderable
part of it which he has to do with, may be apt to think that, in other
mansions of it, there may be other and different intelligent beings, of
whose faculties he has as little knowledge or apprehension as a worm
shut up in one drawer of a cabinet hath of the senses or understanding
of a man; such variety and excellency being suitable to the wisdom and
power of the Maker. I have here followed the common opinion of man's
having but five senses; though, perhaps, there may be justly counted
more;--but either supposition serves equally to my present purpose.

CHAPTER III.

OF SIMPLE IDEAS OF SENSE.

1. Division of simple ideas.

The better to conceive the ideas we receive from sensation, it may not
be amiss for us to consider them, in reference to the different ways
whereby they make their approaches to our minds, and make themselves
perceivable by us.

FIRST, then, There are some which come into our minds BY ONE SENSE ONLY.

SECONDLY, There are others that convey themselves into the mind BY MORE
SENSES THAN ONE.

THIRDLY, Others that are had from REFLECTION ONLY.

FOURTHLY, There are some that make themselves way, and are suggested to
the mind BY ALL THE WAYS OF SENSATION AND REFLECTION.

We shall consider them apart under these several heads.

Ideas of one Sense.

There are some ideas which have admittance only through one sense, which
is peculiarly adapted to receive them. Thus light and colours, as white,
red, yellow, blue; with their several degrees or shades and mixtures,
as green, scarlet, purple, sea-green, and the rest, come in only by the
eyes. All kinds of noises, sounds, and tones, only by the ears. The
several tastes and smells, by the nose and palate. And if these organs,
or the nerves which are the conduits to convey them from without to
their audience in the brain,--the mind's presence-room (as I may
so call it)--are any of them so disordered as not to perform their
functions, they have no postern to be admitted by; no other way to bring
themselves into view, and be perceived by the understanding.
