shape and colour, for so presumptive ideas of several species, that in a good picture, we readily say, this is a lion, and that a rose; this is a gold, and that a silver goblet, only by the different figures and colours represented to the eye by the pencil.

Yet, imperfect as they thus are, they serve for common converse.
But though this serves well enough for gross and confused conceptions, and inaccurate ways of talking and thinking; yet MEN ARE FAR ENOUGH FROM HAVING AGREED ON THE PRECISE NUMBER OF SIMPLE IDEAS OR QUALITIES BELONGING TO ANY SORT OF THINGS, SIGNIFIED BY ITS NAME.

Nor is it a wonder; since it requires much time, pains, and skill, strict inquiry, and long examination to find out what, and how many, those simple ideas are, which are constantly and inseparably united in nature, and are always to be found together in the same subject.

Most men, wanting either time, inclination, or industry enough for this, even to some tolerable degree, content themselves with some few obvious and outward appearances of things, thereby readily to distinguish and sort them for the common affairs of life: and so, without further examination, give them names, or take up the names already in use.

Which, though in common conversation they pass well enough for the signs of some few obvious qualities co-existing, are yet far enough from comprehending, in a settled signification, a precise number of simple ideas, much less all those which are united in nature.
