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.

But the use of words in registring our thoughts, is in nothing so evident as in Numbering.  A naturall foole that could never learn by heart the order of numerall words, as One, Two, and Three, may observe every stroak of the Clock, and nod to it, or say one, one, one; but can never know what houre it strikes.  And it seems, there was a time when those names of number were not in use; and men were fayn to apply their fingers of one or both hands, to those things they desired to keep account of; and that thence it proceeded, that now our numerall words are but ten, in any Nation, and in some but five, and then they begin again.  And he that can tell ten, if he recite them out of order, will lose himselfe, and not know when he has done:  Much lesse will he be able to add, and substract, and performe all other operations of Arithmetique.  So that without words, there is no possibility of reckoning of Numbers; much lesse of Magnitudes, of Swiftnesse, of Force, and other things, the reckonings whereof are necessary to the being, or well-being of man-kind.
