And of Names Universall, some are of more, and some of lesse extent; the
larger comprehending the lesse large: and some again of equall extent,
comprehending each other reciprocally. As for example, the Name Body is
of larger signification than the word Man, and conprehendeth it; and the
names Man and Rationall, are of equall extent, comprehending mutually
one another. But here wee must take notice, that by a Name is not
alwayes understood, as in Grammar, one onely word; but sometimes by
circumlocution many words together. For all these words, Hee That In
His Actions Observeth The Lawes Of His Country, make but one Name,
equivalent to this one word, Just.
By this imposition of Names, some of larger, some of stricter
signification, we turn the reckoning of the consequences of things
imagined in the mind, into a reckoning of the consequences of
Appellations. For example, a man that hath no use of Speech at all,
(such, as is born and remains perfectly deafe and dumb,) if he set
before his eyes a triangle, and by it two right angles, (such as are the
corners of a square figure,) he may by meditation compare and find, that
the three angles of that triangle, are equall to those two right angles
that stand by it. But if another triangle be shewn him different in
shape from the former, he cannot know without a new labour, whether the
three angles of that also be equall to the same. But he that hath the
use of words, when he observes, that such equality was consequent, not
to the length of the sides, nor to any other particular thing in his
triangle; but onely to this, that the sides were straight, and the
angles three; and that that was all, for which he named it a Triangle;
will boldly conclude Universally, that such equality of angles is in
all triangles whatsoever; and register his invention in these generall
termes, Every Triangle Hath Its Three Angles Equall To Two Right Angles.
And thus the consequence found in one particular, comes to be registred
and remembred, as a Universall rule; and discharges our mentall
reckoning, of time and place; and delivers us from all labour of the
mind, saving the first; and makes that which was found true Here, and
Now, to be true in All Times and Places.
