nable, far. jects themselves make on our minds, by the proper inlets appointed to each sort. If plained. they are not received this way, all the words in the world, made use of to explain or define any of their names, will never be able to produce in us the idea it stands for. For words being sounds can produce in us no other simple ideas, than of those very sounds; nor excite any in us, but by that voluntary
connexiori which is known to be between them and those simple ideas, which common use has made them signs of. He that thinks otherwise, let him try if any words can give him the taste of a pine-apple, and make him have the true idea of the relish of that celebrated delicious fruit. So far as he is told it has a resemblance with any tastes, whereof he has the ideas already in his meinory, imprinted there by sensible objects not strangers to his palate, so far may he approach that resemblance in his mind. But this is not giving us that idea by a definition, but exciting in us other simple ideas by their known names; which will be still very different from the true taste of that fruit itself. In light and colours, and all other simple ideas, it is the same thing; for the signification of sounds is not natural, but only imposed and arbitrary. And no definition of light, or redness, is inore fitted, or able to produce either of those ideas in us, than the sound light or red by itself. For to hope to produce an idea of light, or colour, by a sound, however formed, is to expect that sounds should be visible, or colours audible, and to make the ear's do the office of all the other senses. Which is all one as to say, that we might taste, smell, and see by the ears; a sort of philosophy worthy only of Sancho Panca, who had the faculty to see Dulcinea ly hearsay. And therefore he that has not betore received into his mind, by the proper inlet, tachy the simple idea which any word stands for, can never come to know the signification of that word by any other words or sounds whatsoever, put together according to any rules of definition. The only way is by applying to his senses the proper object, and so producing that idea in lim, for which he has learned the name already. A studious blind man, who had mightily beat his head about visible objects, and made use of the explication of his books and friends, to understand those names of light and colours, which often came in his way, bragged one day, that he now understood what scarlet significd. Upon which his friend demanding, what scarlet was? the blind man answered, It was like the sound of a trumpet. Just such an under
standing of the name of any other simple idea will he have, who hopes to get it only from a definition, or other words made use of to explain it.

er of words complex standing for the several ideas that make that instanc composition, to imprint complex ideas in a statue and the mind, which were never there before, rainbow. and so, make their names be understood. In such collections of ideas, passing under one name, definition, or the teaching the signification of one word by several others, has place, and may make us understand the names of things, which never came within the reach of our senses; and frame ideas suitable to those in other men's minds, when they use those names: provided that none of the terms of the definition stand for any such simple ideas, which he to whom the explication is made has never yet had in this thought. Thus the word statue may be explained to a blind man by other words, when picture cannot; his senses having given him the idea of figure, but not of colours, which therefore words cannot excite in him. This gained the prize to the painter against the statuary : each of which

$. 13. Tle that should use the word rainbow to one who knew all those colours, but yet had never seen that phænomenon, would, by enumerating the figure, largeness, position and order of the colours, so well define that word, that it might be perfectly understood. But vet that definition, how exact and perfect soever, would never make a blind man understand it; because several of the simple ideas that make that conplex one, being such as he never received by sensation and experience, no words are able to excite them in his mind. The same of

know the names for them, then we are in a condition to define, and by definition to understand the names of complex ideas, that are made up of them. But when any term stands for a simple idea, that a man has never vet had in his mind, it is impossible by any words to make known its meaning to him. When any term stands for an idea a man is acquainted with, but is ignorant that that term is the sign of it; there another name, of the same idea which he has been accustomed to, may inake him understand its meaning. But in no case whatsoever is any name, of any simple idea, capable of a definition. 1. Names of N. 15.

that hinders not but that they are generally less doubiful and uncertain, than those of mixed modes and substances: because they standing only for one simple perception, men, for the most part, easily and perfectly agree in their signification; and there is little room for mistake and wrangling about their meaning. lle that knows once that whiteness is the name of that colour he has observed in snow or milk, will not be
apt to misapply that word, as long as he retains that idea; which when he has quite lost, he is not apt to mistake the meaning of it, but perceives he understands it not. There is neither a multiplicity of simple ideas to be put together, which makes the doubtfulness in the names of mixed modes; nor a supposed, but an unknown real essence, with properties depending thereon, the precise number whereof is also unknown, which makes the difficulty in the names of substances. But, on the contrary, in simple ideas the whole signification of the name is known at once, and consists not of parts, whereof more or less being put in, the idea may be varied, and so the signification of name be obscure or uncertain,

The reason whereof is, that the lowest species being but one simple idea, nothing can be left out of it ; that so the difference being taken away it may agree with some other thing in one idea common to them both; which, having one name, is the genus of the other two: v. g. there is nothing that can be left out of the idea of white and red, to make them agree in one common appearance, and so have one general name; as rationality being left out of the complex idea of man, makes it agree with brute, in the more general idea and name of animal: and therefore when to avoid unpleasant enumerations, men would comprehend both white and red, and several other such simple ideas, under one general name, they have been fain to do it by a word, which denotes only the way they get into the mind. For when white, red, and yellow, are all comprehended under the genus or name colour, it signifies no more but such ideas as are produced in the mind only by the sight, and have entrance only through the eyes. And when they would frame yet a more general term, to comprehend both colours and sounds, and the like simple ideas, they do it by a word that signifies all
