And of names universal, some are of more, and some of less extent; the larger comprehending the less large; and some again of equal extent, comprehending each other reciprocally. As for example: the name _body_ is of larger signification than the word _man_, and comprehendeth it; and the names _man_ and _rational_, are of equal extent, comprehending mutually one another. But here we must take notice, that by a name is not always understood, as in grammar, one only word; but sometimes, by circumlocution, many words together. For all these words, _he that in his actions observeth the laws 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 deaf 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 equal to those two right angles that stand by it. But if another triangle be shown him, different in shape from the former, he cannot know, without a new labour, whether the three angles of that also be equal 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 only 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 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_.
