Secondly, when the mind supposes any idea it has in itself to be conforunable to some real existence. Thus the two ideas, of a man and a centaur, supposed to be the ideas of real substances, are the one true, and the other false; the one having a conformity to what has really existed, the other not.

Thirdly, when the mind refers any of its ideas to that real constitution and essence of any thing, whereon all its properties depend: and thus the greatest part, if not all our ideas of substances, are false. The cause

This, as I have elsewhere shown, is the reason why we collect things under comprehensive ideas, with names annexed to them, into genera and species, i. e. into kinds and sorts.

§. 7. If therefore we will warily attend to the motions of the mind, and observe what course it usually takes in its way to knowledge; we shall, I think, tind that the mind having got an idea, which it thinks it may have use of, either in contemplation or discourse, the first thing it does is to abstract it, and then get a name to it; and so lay it up in its store-house, the memory, as containing the essence of a sort of things, of which that name is always to be the mark. Hence

it is, that we may often observe, that when any one sees a new thing of a kind that he knows not, he presently asks what it is, meaning by that inquiry nothing but the name.

As if the name carried with it the knowledge of the species, or the essence of it ; whereof it is indeed used as the mark, and is generally supposed annexed to it.

§. 8. But this abstract idea being some- Cause of thing in the mind between the thing that such referexists, and the name that is given to it; it is in our ideas, that both the rightness of our knowledge, and the propriety or intelligibleness of our speaking, consists. And hence it is, that men are so forward to suppose, that the abstract ideas they have in their minds are such as agree to the things existing without them, to which they are referred; and are the same also, to which the names they give thein do by the use and propriety of that language belong. For without this double conformity of their ideas, they find they should both think amiss of things in themselves, and talk of them unintelligibly to others.

Therefore it is seldom, that any one mistakes in his names of simple ideas; or applies the name red to the idea green; or the name sweet to the idea bitter : much less are men apt to confound the names of ideas belonging to different senses;, and call a colour by the name of a taste, &c. whereby it is evident, that the simple ideas they call by any name, are commonly Vol. II.

But in mixed modes we are much more uncertain ; it being not so easy to determine of several actions, whether they are to be called justice or cruelty, liberality or prodigality. And so in referring our ideas to those of other men, called by the same names, ours may be false; and the idea in our minds, which we express by the word justice, may perhaps be that which ought to have another name.

to be different from those of other men,

which are marked by the same names; this at least is certain, that this sort of falsehood is much more familiarly attributed to our ideas of mixed modes, than to any other. When a man is thought to have a false idea of justice, or gratitude, or glory, it is for no other reason, but that his agrees not with the ideas which each of those names are the signs of in other men. And why.

$. 12. The reason whereof seems to me

to be this, that the abstract ideas of mixed modes, being men's voluntary combinations of such a precise collection of simple ideas; and so the essence of cach species being made by men alone, whereof we have no other sensible standard existing any where, but 'the name itself, or the definition of that name: we having nothing else to refer these our ideas of mixed inodes to as a standard to which we would conform them, but the ideas of those who are thought to use those names in their most proper significations, and so as our ideas conform or differ from them, they pass

Nor do they become liable to any imputation of falsehood, if the mind (as in most men I believe it does) judges these ideas to be in the things themselves. For God, in his wisdom, having set them as marks of distinction in things, whereby we may be able to discern one thing from another, and so choose any of them for our uses, as we have occasion ; it alters not the nature of our simple idea, whether we think that the idea of blue be in the violet itself, or in our mind only; and only the power of producing it by the texture of its parts, reflecting the particles of light after a certain manner, to be in the violet itself. For that texture in the object, by a regular and constant operation, producing the same idea of blue in us, it serves us to distinguish, by our eyes, that from any other thing, whether that distinguishing mark, as it is really in the violet, be only a peculiar texture of parts, or else that very colour, the idea whereof (which is in us) is the exact resemblance. And it is equally from that appearance to be denominated blue, whether it be that real colour, or only a peculiar texture in it, that causes in us that idea: since the name blue notes properly nothing but that mark of distinction that is in a violet, discernible only by our eyes, whatever it consists in ;

ideas at the same time; v. g. if the idea that a violet produced in one man's mind by his eyes were the same that a marygold produced in another man's, and vice versa. For since this could never be known, because one man's mind could not pass into apother man's body, to perceive what appearances were produced by those organs ; neither the ideas hereby, nor the names would be at all confounded, or any falshood be in either. For all things that had the texture of a violet, producing constantly the idea that he called blue; and those which had the texture of a marygold, producing constantly the idea which he as constantly called yellow; whatever those appearances were in his mind, he would be able as regularly to distinguish things for his use by those appearances, and understand and signify those distinctions marked by the names blue and yellow, as if the appearances, or ideas in his mind, received from those two flowers, were exactly the same with the ideas in other men's minds. I ain nevertheless very apt to think, that the sensible ideas produced by any object in different men's minds, áre most commonly very near and undiscernibly alike. For which opinion, I think, there might be many reasons offered: but that being besides my present business, I shall not trouble my reader with them : but only mind him, that the contrary supposition, if it could be proved, is of little use, either for the improvement of our knowledge, or conveniency of life; and so we need not trouble ourselves to examine it.
