named it a triangle; will boldly conclude universally, that such equality of angles is in all triangles whatsoever; and register his invention in these general terms, "every triangle hath its three angles equal to two right angles." And thus the consequence found in one particular, comes to be registered and remembered, as a universal rule, and discharges our mental 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 registering our thoughts is in nothing so evident as in numbering. A natural fool that could never learn by heart the order of numeral words, as "one," "two," and "three," may observe every stroke of the clock, and nod to it, or say "one," "one," "one," but can never know what hour it strikes. And it seems, there was a time when those names of number were not in use; and men were fain 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 numeral 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 himself, and not know when he has done. Much less will he be able to add, and subtract, and perform all other operations of arithmetic. So that without words there is no possibility of reckoning of numbers; much less of magnitudes, of swiftness, of force, and other things, the reckonings whereof are necessary to the being, or well-being of mankind.

When two names are joined together into a consequence, or affirmation, as thus, "a man is a living creature"; or thus, "if he be a man, he is a living creature"; if the latter name, "living creature," signify all that the former name "man" signifieth, then the affirmation, or consequence, is "true"; otherwise "false." For "true" and "false" are
